Insulation of a well made of concrete rings. Insulating a well for the winter with your own hands. How to properly insulate a well: various options

The harsh climate of our country has long been known throughout the world. Because of it, our compatriots often have to do work from which people from other countries are exempt. One of these problems is freezing of wells. This can be very serious problems owners and those who use.

Fortunately, in most cases, you can do the insulation of a well yourself, so as not to involve specialists and not pay them a lot of money. But first you need to figure out why, in general, you need to insulate wells.

Many people who prefer to live outside the city both in summer and winter try to insulate wells immediately after construction, because this is the main source drinking water. Those who live in a country house only in the summer do not understand at all why they need to do this. Since they are not going to use them in the cold season, it means that they do not need to insulate the wells for the winter. In fact, this fully applies to everyone.

So, if the water level in the well is quite high, and on the coldest winter days the water can freeze, this leads to the following consequences:

Sometimes arriving in the spring country house, the owners are faced with the need to repair the well, and the cost of such work is quite comparable to the cost of building a new well.

Which wells do not need insulation?

However, it is not always worth spending your time and money to insulate a well. And knowing about this will be very useful. When can you do without insulating a well?

First of all, you should pay attention to the material that was used in its construction. Have you chosen a tree? Then you have nothing to worry about. The water never freezes.

After all, our ancestors built such wells for many centuries and did not encounter any problems. This is due to the fact that wood has excellent thermal insulation properties.

Even if the soil outside the well freezes to a depth of several meters, the water coming from the springs will warm the well to an acceptable level, and wooden walls will reduce heat loss to a minimum.

The only thing that can be recommended in such a situation is to install a cover on the well. This will not only reduce heat loss, but also eliminate the risk of foreign objects getting into the well.

In addition, pay attention to what maximum level the water in the well reaches. If it is located at a depth of 6–8 meters, then you don’t have to worry: the water will never freeze in your well. This becomes possible due to the fact that below the soil freezing level, the temperature never drops to sub-zero levels.

An example of insulating a well from the outside

And finally, it is worth considering in which region of our country the well is located. In the southern regions, winters are often quite warm, so the soil never freezes more than a meter to one and a half meters. Of course, under such conditions, any well, even if it is built from concrete rings and the water is only 2-3 meters from the surface, it will not freeze.

External insulation of wells

When talking about external insulation of wells, experts usually mean at least the covers.

Of course, construction decorative house or a cabin is a rather complicated and expensive matter, especially if you make it attractive so that the well becomes real. But as a result, you get a comfortable cabin that will allow you to comfortably use the well even when difficult conditions- wind, rain and so on.

Example of a well cabin

But still, most people prefer to just install the cover. Even a simple cover made of wood can reduce the heat loss of the well several times. Well, every person can insulate the well cover using polystyrene foam, polyurethane foam or ordinary rags with his own hands. After this, you can be sure that even on the coldest winter days, the well that supplies you with water will not freeze or be damaged.

However, in some cases external insulation not enough. Therefore, experts recommend internal insulation.

A clear example of using a well in winter.

What does internal insulation of wells mean?

For regions where the water in wells lies at a depth of about 3–5 meters, and winters are especially harsh, it is very relevant high-quality insulation well. Installing a cover alone is not enough here - you need to insulate the entire well, including the water pipes. In this case, you can use different materials.

But it is best to insulate the well during construction, so as not to waste extra effort and money on additional excavation work in the future.

As mentioned above, it is not necessary to insulate a wooden well, even one built in a very harsh climate. Therefore, only concrete wells will be discussed here. Let's start with the lid. Of course, a reinforced concrete cover is best suited for a concrete well. She has a very high thermal conductivity, which means it needs additional insulation.

Example of a concrete well cover

Foam plastic has proven itself very well here - cheap, lightweight, easy to install and has a very high thermal insulation. Alas, such insulation cannot be done with your own hands. This means that you will have to order both the material and its transportation and installation. As a result, you will have to shell out a considerable amount.

Another popular option is suspended ceiling. It is very easy to make, the materials can be purchased at any hardware store, which means you don’t have to spend extra money, since you can do all the work yourself.

The suspended ceiling must be installed below the soil freezing level. However, you should make sure that the lid does not come into contact with water. To make it you will need moisture-resistant plywood, film and suitable insulation. Measure the diameter of the well and cut out two panels of a suitable shape and size.

Sample of an insulated cover for a well

One of them must be wrapped in film: it will protect against splashes, thereby increasing the service life, and also prevent the occurrence of mold on the plywood.

Insulation must be laid on top of this shield. Polyurethane foam or polystyrene foam is best. You can also insulate the lid with foam. But mineral wool, which has proven itself as insulation, will not work here. It will probably crumble and fall down. As a result, water saturated with mineral wool particles will become completely unsuitable for use.

A second plywood panel is laid on top of the insulation. Here the opinions of experts differ significantly. Some recommend doing a small air gap between the insulation and the second shield, motivating this by strengthening thermal insulation characteristics. Others advise laying plywood directly on the insulation, arguing that the thermal insulation of the cover will be sufficient anyway. Which of these options should you choose? Only you can make the final decision.

To avoid problems with freezing of the well, it should be properly insulated. IN winter time Frost and ice form on the outside of the shaft neck. This occurs due to the temperature difference between inside and outside.

Icing of the chamber walls creates additional difficulties in the operation of the water supply and sewerage system, and also impedes repair work.

Here are some ways:

Well insulation.
Construction of a small house made of wood or stone over the chamber.
Thermal insulation of the collector cover, if the well itself is located below the freezing level of the soil.
Insulation with natural materials.
By using construction funds, foam plastic or basalt insulation.
Install a well or caisson below the freezing level of the soil.

Wooden house

A common option for the cold season, if the site is located in a place where the average depth of soil freezing is no more than 1.5 meters.

Installed on the very top of the well or sewer. An integral element construction is the installation of a door or window that opens as needed. It must be correctly positioned in the front part or in the slope itself. It all depends on technical capabilities.

Important: during construction everything wooden parts It is worth treating with a protective compound against the formation of mold in a humid environment.

Before starting construction of the hut, the source will still have to be insulated (foam plastic, expanded polystyrene, covering material, old sweatshirts).

Protective waterproofing is laid along the entire perimeter of the shaft walls.

Thermal insulation of the cover

This happens in several stages.

First stage . To make a pie, you will need two panels of plywood or moisture-resistant chipboard and a piece of polystyrene foam or polystyrene foam. A round washer is cut out of plywood to match the inner diameter of the well ring. If the chamber is square, then cut out a square according to the internal markings of the caisson. A piece equal to the rest is also formed from the foam.

Stage two. Using wood glue, the pie is held together, leaving foam between the panels. To further secure these layers, you can screw in screws. A handle is installed on the top of the washer, making it easier to remove and reinstall the lid.

Third stage. Insulation of the well summer cottage complicated by rare inspection of the inside of the collector. Not all owners audit the source. Therefore, the installation of the insulated cover must be securely fastened. To prevent the puck from falling into the water or onto pumping equipment, but remains at ground level and needs to be secured. Four holes are drilled crosswise in the shaft wall at a depth of 50–60 centimeters from the lid, and a small piece of reinforcement is driven into them. 2-3 centimeters should stick out inside the ring. The insulated pie will rest on these ledges.

Important: if the ground freezes below 2 meters, you should make two such washers and install them 15 centimeters apart. This will create an additional air curtain.

How to insulate a mine made of concrete rings for the winter

This question torments all summer residents and owners. country houses. There is no need to insulate the entire well. It is enough just to cover the topmost concrete ring.

Polystyrene foam or expanded polystyrene are similar in shape and installation method. These materials are produced in rectangular slabs.

For a tight fit, they will have to be sawn lengthwise into smaller strips. Having previously been lubricated with foam or special glue, they are pressed against the walls of the reinforced concrete rings from the outside.

We coat all cracks and joints with foam from a balloon. It is advisable to protect the foam from exposure to soil and moisture.

A layer of roofing material or waterproofing material. Afterwards you can bury it.

DIY sewer insulation

The same technologies and materials are used as for aquifer chambers. The only difference is in the depth of laying the main systems. The sewer line is located above the water pipeline, so the likelihood of freezing is more pronounced.

In thermal insulation of a sewer well, it is important to combine several methods, for example, to insulate not only the top ring, but also the collector cover.

What to do if you're already frozen

Having opened the well, it is clear that frost has covered the entire area of the walls of the ring and has tightened the pumping equipment. Perhaps the installation depth of the cover was incorrectly calculated, or the source was not insulated correctly.

If there are signs of freezing, but water is still flowing into the house, nothing needs to be done until the air temperature rises. Then it should be properly insulated.

Frozen equipment can be warmed up with a hair dryer right on the spot, or, after removing it, bring it into a warm place and let it stand for a day.

Insulated cover:

Well water is considered clean and healing.

The owners monitor its quality through constant repair work.

Today, a well made from a well has become a common type of installation of a water source. concrete rings.

One of the requirements for its use is insulation for the winter period.

To do such work yourself, you should study the recommendations and advice of experts, those who have already carried out similar actions on their site.

Why is well insulation required?

Ice not only prevents you from getting water from a well, it contributes to the formation cracks and chips in concrete. If the well is brought cable or pipe, their quality also deteriorates.

Cable rupture and pipe freezing will require repairs, which will be both complicated and expensive. It is especially dangerous if the log house is not insulated, freezes and thaws several times during the winter.

Rings are destroyed and grow old. The concrete structure itself won't last a person as much as he expected.

Measures against freezing

When installing a well on a site, experts advise to think in advance about the possibility of it freezing in winter period.

Already during the work of digging out a source of drinking water and its construction, a number of works are carried out for protection concrete structure

Even if it is used for a short period of time, a number of protective measures must be taken.

processing of log walls disinfectants means;
pumping out water and drying the log house;
laying water pipes on the right level: below the soil freezing level;
additional pipe installation and fastenings of pumping equipment;
protection of concrete from impact natural phenomena , destroying its quality.

Insulation methods

The main requirement when carrying out construction work – conservation ecology of the internal environment and water composition.

All materials used for insulation must not violate quality water. In addition, materials are divided according to functional tasks.

What is used outside, not necessarily suitable for internal processing.

Cover insulation

The cover can be made from various materials:

wood;
reinforced concrete;
plastic.

Tree - unique material, it does not require additional insulating layer.

A lid can be made from wood double: inside the concrete ring and outside

Internal will moderate temperature changes. External protects from dirt, snow and debris.

The second material (reinforced concrete) differs in durability operation, strength and reliability.

Plastic ceiling is installed inside concrete frame, approximately at the level of the top layer of soil.

Manufacturing method insulating structure closing:

Two shields are cut out, the material is plywood moisture resistant quality.
One is being processed waterproof mixture, wrapped in film, cellophane or other material to protect against moisture penetration.
3attached inside the rings metal rods, on which the first shield is laid.
Spreads out insulation, Any will do building material other than mineral wool.
The second one is fixed shield, also treated with insulation.
All layers are fastened and wrapped waterproof cloth or cellophane.

The lid made in this way is supplemented with a pen, it is needed for ease of lowering and raising.

Insulation of well walls

Options There are quite a lot of insulating materials offered by trade organizations.

The choice remains with the developers. To insulate the walls, they dig outside trench. Its depth depends on level soil freezing.

There are few types of insulation that are popular:

There are many advantages of the material:

not subject to rotting;
does not deform under mechanical influence;
withstands the statement coming from the soil;
easy;
easy to install;
wear-resistant;
difficult to burn.

The last stage of work, after selecting the material and insulating the concrete structure with it, is digging a trench

Now the well will not be afraid of severe winter cold.

For the safety of the manufactured log house, when getting water with buckets or through hoses, they try to prevent water from getting on wall surface. Ice will damage the concrete and reduce its service life.

External insulation

On the outside, various types of insulation are built houses. Their shape depends on the wishes of the developers.

Nadkolodezny the wooden frame will serve both as a design for the concrete structure and as insulation.

Tree retains heat and is easy to work with. Any design can be made from wood; it lends itself to painting and other design details.

Such houses become decorative decoration total personal plot. Concrete rings round in shape, wooden log houses have corners.

Therefore, air remains between the rings and the tree. space. Experts advise filling it out expanded clay, it will complement the insulating functions of the external log house.

Any heat insulator, properly used for insulation, will protect against frost and temperature changes. In the instructions describing the steps construction activities, a list is given necessary tools.

You can get ready, experiment on small areas, then proceed to the main work. Insulation is considered completed after insulating the lid, walls and outer surfaces.

All work is simple in technology and is possible for independent execution. The water will be protected from severe frosts and will remain clean and healthy at any time of the year.

The coolness of the water will delight users and lovers clean water from the bowels of the earth.

Uninsulated the construction of a concrete frame will require urgent capital repairs. The cost of the work will correspond to the installation of a new one.

Pumping equipment is better stored and operates during insulation.

Preface. In the article we will examine the important issue of how to insulate a well for supplying water to a house, how to insulate sewer well in a private house for the winter. First, let’s look at why insulation of a concrete well is necessary, what an insulating cover for a well consists of, and what materials can be used to insulate a well for the winter with your own hands. At the end we will show a video on insulating a well.

Wells made of concrete rings, in which the groundwater level is quite high, often freeze in winter. An ice plug is created, the thickness of which reaches up to 50 cm in cold weather; often the water supply and sewer wells completely freeze to the bottom. Due to the fact that it is often impossible to remove the plug, it is necessary to carry out proper insulation water well with your own hands, so as not to encounter such a problem again.

Why is it necessary to insulate a water well?

Why is everyone so afraid of a well freezing? If this disaster happens, then you will have to invest a lot of money in repairing the well on the site and restoring the area around it. Under the pressure of expanding ice, the concrete rings shift and collapse - cracks appear, and the concrete collapses much faster. Here are the most common reasons for freezing of wells in country houses in winter:

displacement of concrete deck rings;
rupture of seams between concrete rings;
freezing of the water supply system;
broken pipes and power cable pump;
failure of the soil around the well.

How to insulate a well with your own hands for the winter

We insulate the top ring (insulating cover for the well) using plastic cover from combined thermal insulation materials. Of course you can do it decorative log house in the form of a house, it all depends on your financial capabilities and imagination in this matter.

Inexpensive way To insulate a well for the winter with your own hands is to make a sandwich lid, which includes: top layer wood, in the middle there is a layer of polystyrene foam and the bottom layer is moisture-resistant plywood, which is not afraid of moisture and condensation.

No less convenient and effective solution, if you decide to insulate the well yourself, install a reinforced concrete cover on the well with a polymer-sand hatch.

It does not need to be removed for the summer - the service life of such a cover is equal to the service life of the well itself, so there should be no problems with operation. And the question of how to insulate a well made of concrete rings for the winter can be safely resolved in the summer.

How to insulate a concrete well with foam plastic with your own hands

If you do not want to pay extra money and contact specialists, then you can insulate a water supply well using polystyrene foam on your own. To do this, you need to stock up on polystyrene, which is sold in the form of a semicircular shape (“shell” made of polystyrene foam). The range of insulation is presented different diameters and thickness, from which you can easily select the desired option.

Insulation with foam plastic or penoplex

Polystyrene is resistant to moisture, the appearance of fungi and mold, and mechanical soil pressure. It does not rot, does not absorb water, does not emit harmful substances, and no mice live in it. That is why polystyrene foam can be easily used even after possible repairs well for the second time.

Before insulating a concrete well with polystyrene foam, you need to dig a trench 1.5 meters deep along its perimeter or to the freezing depth of the soil in your region. Then, we select a polystyrene “shell” to match the diameter of the concrete rings and install insulation around the source. After this, the trench is buried. Semicircular polystyrene has a convenient tongue-and-groove fastening, so they are often used when insulating water pipes in the basement.

How to insulate a sewer well with your own hands

According to the standards, a sewer well must be sealed, that is, the bottom and walls of the well must be tightly concreted. But in practice, for the construction of sewage wells they use various materials– red or sand-lime brick, sewer wells from car tires. But it is better to use reinforced concrete rings for the construction of sewer wells.

Whatever material the fecal well is made of, it must be insulated for the winter. In order to insulate cesspool for the winter, you effectively need to do the following set of actions that will really protect the sewer well from frost:

1 . it is necessary to protect the upper part of the cesspool

The first step is to insulate the well cover; in addition, it will not be superfluous to insulate sewer pipe, through which sewage from the house flows into a cesspool.

2 . install insulation around the cesspool

This procedure is identical to the procedure described above when insulating a well for supplying water to a house.

There is nothing complicated about the question of how to insulate a sewer or water well for the winter. The work can be done by everyone. The most important thing to remember is that the well freezes because there is access to cold air to the water. When there is a tight lid on top, on which you can throw a pile of snow in winter to dig up, then the water in the well will never freeze in the most severe frost.

How to properly insulate a well for the winter video instructions

When building a private house, an autonomous water supply is installed. A well or borehole serves as a source for it. The system should work uninterruptedly, but in winter problems may arise due to freezing of hydraulic structures. They need thermal insulation. Let's consider how to properly organize the insulation of a well or borehole in order to save as much effort, time and money as possible.

Which structures need insulation and why?

Some wells do not need additional thermal insulation; it is enough to cover them with a sealed lid. These are structures built according to old technology- With wooden walls and a log house. Wood holds heat well. If the shaft is covered with insulated wooden lid and build a house, the problem is solved automatically. The water in such a well will not freeze even in the most severe frosts.

The situation is completely different with structures made of metal and concrete. These materials are durable and can cope with any mechanical loads, but do not have any special heat-insulating properties. It is necessary to think about how to insulate a well made of concrete rings. If the aquifer lies relatively deep, a decrease in temperature will not affect the operation of the water supply system, but in shallow wells the water becomes covered with an ice crust.

Scheme autonomous water supply from the well

Low temperatures and differences negatively affect the performance of the well: in cold weather, pumping equipment fails, casing and supply pipes freeze and perform their functions worse. To prevent interruptions in water supply, it is necessary to select effective insulating materials and install them correctly.

Advice. It is best to carry out measures to insulate a water supply well immediately after its construction and arrangement. In unfavorable conditions, the structure may not survive even one severe winter and will require overhaul.

How to insulate a well for the winter with your own hands

Ground parts of hydraulic structures, as well as those located at ground level, need thermal insulation. When insulating a well for the winter special attention pay attention to the top ring and cover. In most cases, it makes sense to build a house.

The following nuances need to be taken into account:

Top ring. This part of the structure must be insulated, because... Temperature changes over time can lead to cracks. Through them they enter the mine surface water and pollute the drinking well. Polystyrene foam, polyurethane foam, isolon are usually chosen as insulation materials. mineral wool.

Cover for a well. In addition to the top cover, a special cover is made for the well at ground level. It protects the mine from debris, atmospheric water, and temperature changes, so it must be durable, without cracks or cracks. For better thermal insulation, this cover can be additionally trimmed with any available insulation. Polystyrene foam is often used.

Little house. In regions with harsh climates, the house must protect the entire above-ground part of the well. Ideal option, if it is made of wood and additionally insulated from the inside. In areas where winters are mild, you can build a light roof or do without a house at all.

Stage 1: making a warm cover for the well

For the lid you will need plywood, good glue, wire, foam plastic with a thickness of 5 cm, polyurethane foam. It is advisable to immediately take care of ventilation, because... A tightly closed well often rots. Bacteria multiply in the water, making it unsuitable for drinking and cooking. A small section is used as ventilation plastic pipe suitable diameter.

Work order:

Two circles are cut out of plywood. Their diameter must match the diameter of the top of the well.

In both plywood circles, holes with a diameter of no more than 6 cm are cut under ventilation pipe and a hose. You will also need to drill 4 small holes for the wire on which the structure will be supported.

The same circle should be cut out of the insulation as from plywood, and the corresponding holes should be made in it.

The insulating layer is placed between sheets of plywood and firmly glued on both sides. Seams and joints are sealed polyurethane foam.

All that remains is to install the ventilation pipe and pass the hose into the hole.

The finished well cover is attached to a wire through 4 holes and lowered to the required depth (to ground level).

Covering from moisture resistant plywood

Stage 2: how to insulate a well “under a fur coat”

To insulate a well with polystyrene foam, you will need to buy the heat insulator itself, polyurethane foam, paint and plaster. It is best to take polystyrene foam in the form of blocks with a tongue-and-groove connection. It is necessary to insulate two concrete rings: the first completely, the second partially. Since this provides earthworks, you will need a shovel and tools with which you can clear the soil from the concrete.

Mounting polystyrene foam on a ring

Insulation of a well with polystyrene foam:

The well rings are dug to a depth of about 0.5 m. The width of the hole should be at least 20 cm. The concrete is thoroughly cleaned of clods of earth, after which the first layer of “coat” is made. The cracks are filled with polyurethane foam.

A heat insulator is mounted on top of the finished coating. It is attached with glue, and the gaps that form during operation are filled with foam.

Insulated rings are plastered. When the solution is completely dry, apply a layer on top of it facade paint. It is needed to protect the inner layers of the insulating cake from getting wet.

After the paint has dried, the hole is filled with the excavated soil and compacted well. Expanded clay can be used as an additional insulating layer.

Expanded polystyrene is not the only material that is used to insulate a well. You can use mineral wool or any other insulator. An excellent option is polyurethane foam. To apply it you will need a special sprayer, and the technology itself is quite complex. However, the result is worth the money and effort spent: the heat insulator does not rot, is not afraid of water, rodents, insects, fungus, mold. It can last for many years without losing its properties.

Insulating a well for the winter with your own hands using polyurethane foam:

A pit about 0.5 m deep and 10 cm wide is dug around the structure, after which the bars are installed in increments of 40 cm.

Next, make formwork from sheet steel and carefully close it plastic film. This is necessary so that the formwork can be removed later. Polyurethane foam firmly adheres to any materials, so the film will stick to it forever.

When the material hardens, it expands, so the entire pit cavity will be filled. If gaps and voids remain, they can be filled with foam. The insulation layer must be complete, without cracks.

When the polyurethane foam has dried, the formwork is removed, and the surface is plastered and painted in the same way as when insulating with foam plastic. The hole is filled with earth and compacted.

Pay attention! Insulating a well with polyurethane foam is always reliable, but it is better to make an additional cover at ground level. In severe frosts it will be useful.

Polyurethane foam is a reliable heat insulator

Stage 3: building a warm house for the well

There are several options for arranging a well house. Good choice– hexagonal structure, insulated with polystyrene foam. This shape is best suited for finishing with insulating material: it will firmly adhere to surfaces. To build a house of this type you will need sheets of plywood, insulation, waterproof film, logs, wire (preferably aluminum), nails, and tools. A drawing with dimensions is shown in the figure below.

Diagram of a hexagonal house with a roof

Work order:

The top ring of the well is covered with a waterproof film.

Insulation sheets are cut into 6 identical rectangles so that during installation they tightly surround top part well.

The insulating material is mounted around the ring and secured with wire.

The next stage is the construction of a hexagonal frame around the top of the well. It is also advisable to make a roof so that rain and snow do not fall on the cover.

The finished structure can be decorated with carvings, decorative elements. Such a house will serve not only as protection for the well, but also as a landscape decoration.

Video: installation of roll insulators

You can also thermally insulate the upper ring of the well using isolon or other rolled materials. How to do it yourself is shown in the video below:

Basic methods of well insulation

Water in wells rarely freezes, because... structures are drilled to quite great depths. If the water supply is used only seasonally, it is better to preserve the well for the winter. And in private houses, where it is necessary to ensure uninterrupted water supply, the upper part of the pipe and the supply line to the house are insulated.

When considering options for how to insulate the upper part, it is better to choose a caisson for a well. It is installed below the soil freezing level. If the structure is sealed, then additional protective measures will not be required. You can also build an insulated box that will cover the head of the well. Equipment is also located here.

Advice. In areas with a warm climate, it is quite possible to get by with a protective box-house, but where there are severe frosts, it is better not to skimp on insulation and install a caisson.

Sometimes wells are thermally insulated using improvised means - sawdust, straw, etc. Such half measures only save you for a couple of years. Natural materials quickly rot and lose their heat-insulating properties. You will have to replace them very quickly, otherwise problems with water intake will arise. It makes sense to spend money on high-quality insulation, but ensure reliable protection source for many years.

Option #1: building a caisson from a barrel

How to insulate a well for the winter with your own hands? The most reasonable solution is to buy a ready-made insulated caisson industrial production and entrust its installation to the specialists of the selling company. However, this is the most expensive option. If you want to save money, but get no less reliable design, the caisson can be made independently.

You will need a plastic or metal barrel for 200-500 l. You can take a used one if the walls are not damaged or corroded by rust, and the lid closes tightly.

As for the volume, you should choose based on the functions that the improvised caisson will perform. A 200-liter pump can accommodate a maximum pump, but a volume of 500 liters should be enough to install everything necessary equipment.

How to insulate a well on the street using a caisson:

A pit is dug around the pipe to the level of soil freezing plus another 40 cm. The width of the trench should correspond to the size of the barrel plus another 50 cm. The bottom of the hole is covered with a 10-centimeter layer of sand and gravel mixture.

Holes are cut in the container for the well head and water pipe. After this, the barrel is put on the well pipe and lowered.

When the structure is installed, you can connect the water supply pipe and install a condensate drain pipe.

For additional insulation The caisson uses polystyrene foam, mineral wool, and isolon. The heat insulator is mounted on the outside of the barrel and secured.

A hole is cut in the lid of the barrel and a ventilation tube is installed. The lid itself is insulated with the same material as the walls.

At the end of the work, the pit is filled with the excavated soil and compacted thoroughly. The caisson is ready for operation.

Option #2: arrangement of a box-house

To insulate a well, you can build a wooden, metal or brick box with your own hands. It is made in the form of a small house with a pitched roof to protect it from snow and rain. They are insulated from the inside - with polystyrene foam or mineral wool. The dimensions of the box should be such that everything fits freely in it. downhole equipment.

Insulated box for the well head

Work order:

The walls of the box are laid out from bricks, blocks or made of plywood.

The surface of the walls is leveled, if necessary. Polystyrene foam is mounted on adhesive composition. Seams, gaps and joints are sealed with polyurethane foam.

The insulation is closed chipboard sheet, fasten.

The lid is made in the form pitched roof, insulated, hung on hinges. If necessary, you can close the box with a padlock.

Option #3: use scrap materials

How to insulate a well in a region with a mild climate? If the temperature in winter does not drop below 15 degrees, and the owner of the well does not want to install a box, you can make do with sawdust, straw or dry leaves. The first option is preferable.

Sawdust as insulation

Insulating a well for the winter with your own hands:

Around casing pipe dig a pit 0.5 m deep below the freezing level of the soil. The width of the hole depends on the amount of materials with which it is planned to fill it.

Dry insulation is laid in layers in the foundation pit and compacted.

When the insulation layer is almost equal to the ground level, soil is poured on top and compacted thoroughly.

Advice. You can equip not just an insulating, but also a waterproofing pillow. To do this, sawdust is mixed with liquid clay. The resulting mixture is placed in a pit and covered with soil. Clay will additionally strengthen the soil around the hydraulic structure.

There are often disputes on the Internet about the advisability of insulating wells and boreholes for the winter. Some users believe that in the southern regions this is an unnecessary waste. However, sensible owners are well aware that even in the warmest region there are severe winters, and measures to thermally insulate the source are much cheaper than repairs. It is necessary to insulate the water intake, and this must be done efficiently.

If a hydraulic structure is insulated, the temperature in it does not fall below 5 degrees. Water does not freeze even in severe frosts, and the walls of the structure suffer less from temperature changes. The biggest trouble that can happen is freezing of the supply pipe at the entrance to the house. The ice plug is simply melted using hot water, and system operation resumes. Otherwise, no problems.
