The scale of construction, which is gaining momentum every year, stimulates the development of technology. At construction sites, to facilitate and speed up work, a variety of equipment appears.

On large construction sites, the use of a concrete pump makes the job especially easier. The use of modern technology for the supply of concrete solution significantly increases the productivity and quality of work.

1 Features of using concrete pumps

A concrete pump is a difficult technique to use. Using the device has the following features:

• work with the unit is permitted only to high-class specialists;
• it is necessary to comply with technology and operating rules;
• be responsible for organizing and preparing work;
• use special concrete mortar, taking into account the diameter of the supply hose, the conditions for supplying the mixture to a certain place and the distance.

Having considered the features of the use of such equipment, we can conclude that the concrete pump is mainly used in impossible or difficult conditions for supplying the mixture. For example, dense buildings, it is difficult to drive to a construction site, or you need to pump the solution to a large height - the concrete pump can easily cope with such difficulties.

1.1 Types of pumps

During operation, the principle of displacement operates on the unit; a volume is created in the system, which can change. This principle divides pumping devices into two types: piston and gerotor.

1.2 Concrete pump in operation (video)

1.3 Piston devices

In piston machines, concrete is supplied continuously. Today, equipment can supply concrete mixture to a height of 6-65 m, the volume of solution supplied reaches 180 m³/h. Small particles of cement sometimes get caught between the surfaces of the pistons that rub, so the piston device has a short service life.

The concrete solution flows in spurts. There are devices with hydraulic device, which are characterized by durability and deliver concrete softer. At the same time, the feed speed does not change, and the high pressure makes it possible to deliver over long distances. The operation of two-cylinder devices is so soft that it is almost unnoticeable.

1.4 Gerotor pumps

These are auger devices with a continuous supply of concrete solution. The characteristics of gerotor technology allow you to work silently with a composition of any hardness. When a blockage forms in the hose, it is removed using a motor that can change the direction of rotation. The main disadvantage of the gerotor design is the rather rapid wear of the hose for supplying the mixture. But the advantage is the low cost of repairs, which can be done without the intervention of specialists.

1.5 Concrete mixer

Delivering concrete mix to a construction site is not an easy task. Incorrect actions may well ruin the quality of the solution. Using a concrete mixer truck prevents such nuances. A concrete mixer with a pump is attached to a car chassis. The inside of the iron barrel is equipped with blades. The clockwise movement of the barrel helps the mixture move inward, and when the reverse process is turned on, it pushes the concrete mixture along the blades to the discharge hole.

Advantages of using a mixer:

• the homogeneity of the mass is maintained and stratification of the solution is prevented;
• the solution is constantly in motion, even with delays, which helps maintain the technical characteristics of the material.

The capacity of the barrel allows you to move or prepare up to 9 m³ of concrete solution. The concrete mixer is equipped with a loading tray for pumping ready mixture to the construction site. They use such transportation when you can easily drive up to the construction site. If there is no access to the building site, a pipeline is used, which is an in-building technique. The use of such a device has the following technological advantages:

• horizontal and vertical movement using one equipment;
• ease of work in hard-to-reach places.

Pipeline equipment – ​​devices for supplying concrete mixture or a separate type of construction equipment. A separate technique involves installing a pump on a car using a rotating boom. Such devices allow transportation of the solution in a vertical or horizontal position for auxiliary structures.

The delivered mixture is moved through trays to the pump receiver, and through a pipe, which consists of three parts, the solution is supplied to heights and to hard-to-reach places.

1.6 Stationary pump

Based on the principle of operation, the devices are divided into standard, trailed, mobile, or truck-mounted concrete pumps. The equipment can be equipped with a mechanical or hydraulic drive. The main parameters of construction units: feed height, productivity and distance.

A stationary concrete pump can be made in several versions and installed on a flatbed truck or a special platform, which is responsible for ease of movement. It is worth noting that the design is made in the form of a trailer with a chassis, and ensures a continuous supply of the mixture. It is very easy to transport such equipment by hooking it up to a truck.

The operating principle is based on continuous pumping of a large amount of concrete mass. The design of the device has two modes: supply of the mixture under high pressure (in this case, work productivity is significantly reduced), and low pressure mode (with greater productivity).

1.7 Pumping solution with a gerotor pump Sosna

The mechanical engineering company StroyMechanika offers the buyer a gerotor (screw) unit CO 78.300/500/1000 Pine. The Pine gerotor pump pumps viscous and abrasive masses, materials that differ in density (foam concrete, polystyrene concrete), and cellular concrete solutions. The device is used for pressure supply of multicomponent and complex masses that are sensitive to mechanical stress. Also, the device supplies paste and liquid solutions with solid particles or fibers.

2 Design

The mortar pump is equipped with a hopper for receiving material from the mixing plant. The presence of a supply hopper makes it possible to continuously supply material when using cyclic mixing technology. This is an important condition for work where interruption is unacceptable (filling forms, mechanical application of plaster material, etc.). To facilitate transportation, the devices are equipped with a wheeled chassis.

The feed part of the screw technology consists of a gerotor steam and a feed auger. The single-thread screw (moving part of the steam) makes planetary motion in the stator, which has an internal double-thread surface with a pitch twice the pitch of the screw. With constant contact, the screw and the cage create several closed cavities.

As the screw moves, the cavity on the suction side increases, in which a vacuum is formed. Under the influence of such a vacuum, the cavity is filled with the pumped material. This design helps to move foam concrete, plaster and polystyrene concrete mixtures as carefully as possible.

Gerotor concrete pumps, with their small dimensions, have high performance; they allow you to pump working material into voids, pump mixtures for self-leveling floors, and supply and apply plaster solutions.

2.1 DIY concrete pump

Before assembling the main components of the device, you need to create a plan or make a drawing. This will help to assemble all the equipment into one unit. The main elements of the mechanism are the piston and cylinder.

All components and parts of the concrete pump are made using a lathe. When adjusting key parts, the accuracy of the error must be at least ±0.1 mm. The base for the case is made of stainless steel sheet, which will help avoid corrosion and chemical influences. The valve is adjusted using a screwdriver. The structure is being assembled wrench required diameter. The drive part of the device is performed hydraulically or electromechanically.

The choice of method depends on the financial capabilities of the master. After all, a hydraulic drive has a more complex design and a high price level. Therefore, you should make your choice in favor of an electric drive unit.

Basically, a three-phase asynchronous electric motor is used, which is connected to the piston head rod. A mechanical converter and torque reduction gearbox are used to reduce the load.

2.2 Installation of the unit

The electric motor is mounted on the axial base of the trailer. The gearbox is mounted on the motor shaft using a coupling. The converter is connected to the pump piston and the output shaft of the reduction gearbox. Then connect the motor to the power cable.

When assembling the concrete pump you will need following materials:

• drawing supplies;
• iron sheet up to 6 mm;
• blanks for piston and valves;
• metal pipe with a diameter of 400 mm;
• three-phase electric motor with starter;
• a set of locksmith tools;
• gearbox with reducing torque;
• car trailer or welded base.

Concreting is the most common type of work in construction; it is used in most areas. To make working with heavy mortar easier, special devices for preparing and transporting cement have become widespread. The simplest but most expensive way to move mortar is with a concrete pump, but the cost of installation puts off small firms. It is possible to create a concrete pump with your own hands, and the costs will be 30-40% less.

Operating principle of a concrete pump

A concrete pump is a device with the sole task of preparing and delivering concrete from the mixing point to the target area. The installation is based on pipelines or concrete pipes that transfer the solution to any location. The greatest need arises in monolithic construction and when creating reinforced concrete structures.

To understand the method of constructing the installation, you should know how a concrete pump works. The operating principle of a concrete pump is based on the properties of the liquid - it displaces and fills the changing volume of the system. If the volume is completely filled with the mixture, the solution is discharged into the concrete pipeline and then to the target area.

The design and principle of operation of a concrete pump is divided into several groups:

• piston Perform a constant feed at various distances. Modern devices are capable of displacing liquid to a height of 6-65 m. The volume of the supplied mixture reaches 180 m3/h. It is not durable due to the risk of small elements of cement getting in. Has a jerky delivery principle.
• hose (screw). Provide continuous transportation. The gerotor pump for concrete provides a large volume of transported material. The installation is characterized by silent operation when pumping compounds of any consistency. If a blockage occurs, it is broken through by reversing the engine. A gerotor pump for pumping concrete has one significant drawback - the hose has a short service life, but the structure can easily be repaired independently;
• with hydraulics. If there are hydraulic units for working with concrete, the devices become more durable and smoothly transfer the solution (without jerking or changing speed). Hydraulics help pump liquid to heights and long distances. The hydraulic drive is made as simple as possible; the device results in low energy consumption. Hydraulic pumps help pump mortar containing lightweight aggregates and are easy to operate and maintain.

Drawings of concrete pumps for DIY production differ significantly depending on the type. All models differ in design, but have similar disadvantages to a greater or lesser extent:

• the use of rolling stock is mandatory;
• limited transportation range;
• demands on the composition of the solution.

The price of a homemade concrete pump directly depends on the required power and pipe diameter. For larger pipes the pressure decreases. Recently, concrete pumps (the ability to supply concrete to a target area of ​​​​various distances) and concrete pumps (smaller dimensions and mobility) have become very popular.

Unit types

Conventionally, devices are divided into 2 categories: with a mechanical unit or a hydraulic element. Rotary and piston concrete pumps have their own operational advantages and disadvantages.

Operation of the piston system

Piston systems operate on the same principle in all applications. At the stage of downward movement, a certain volume of liquid and concrete receiver is sucked in; in the second cycle of work, the solution is pushed out into the transfer sleeve. The mixture is supplied to the working area through the pipeline.

The operation requires the use of a slide gate, which opens the concrete receiver during the suction stage and closes it during the ejection process. The gate regulates the direction of fluid flow. During testing, it is necessary to add machine oil to the working mixture.

The design includes a mechanical drive or a hydraulic system. Modern concrete pumps work with hydraulics, since the system is highly efficient, it leads to the formation of greater pressure and increased pump power. Compared to the connecting rod assembly, hydraulic system provides a larger piston stroke range and smoother movements. A potential problem is loose contact between the piston and the chamber. Microscopic particles of cement penetrate between the piston and cylinder, accelerating wear many times over.

Devices with 1 cylinder are practically not used, as they lead to a pronounced pulsation of the solution supply. Mostly, two cylinders are built into the system; they work alternately - so the concrete is supplied smoothly and continuously. Also, a mechanism with two cylinders wears out less.

Rotor system operation

The use of rotary concrete pumps is much more common, since pistonless systems are more reliable. It is based on a rotor with fixed rollers (covered with rubber). As the rotor rotates, the rollers move, transferring the mixture from the concrete receiver to the working hose. An important advantage is the reverse function to remove air pockets and blockages.

Equipment operation and repair are easier. The weak point of the structure is the wear of the hose or seals - both faults can be easily eliminated with your own hands. Other disadvantages include low power (compared to the piston type) and poor tolerance of coarse filler.

There are also screw pumps for pumping concrete, but they are inferior in durability and performance. Their operating principle is elementary: a screw is placed in a through chamber, which displaces the substance during rotation.

Rotary mechanisms are presented in many modifications, the main difference is the method of placement: stationary and automotive.

Unit mounting options

Stationary pumps

Before making a concrete pump with your own hands, you should decide on the type of base it will be based on. The stationary option is a separate station for pumping the substance. Dimensions vary widely; there are concrete pumps for small-scale construction and the construction of industrial facilities. A chassis is often installed for movement.

A mobile structure without a chassis predominantly has high power; it is recommended to use a concrete pump to supply large-scale construction, most often high-rise buildings, with the substance. If there is a chassis, transportation over long distances is not provided; they are intended for movement within one area.

Today, a new type has been developed - a towed device; it is distinguished by a powerful chassis that allows the installation to be moved over long distances by a tractor. For the construction of private housing or household structures, a mini concrete pump with a piston mechanism has been created, less commonly found with a pneumatic drive. It helps when working with small orders or in cramped conditions.

The pneumatic installation is designed to work with homogeneous cellular solutions; it is characterized by low power and the need to connect a compressor, but a stable supply of solution.

Pumps on a car base

The automotive type of pump is the most common in all areas of construction. Like other gardening equipment on wheels, the concrete pump can be easily moved independently, and also has characteristic differences:

• a stationary station with high power is applicable exclusively for large-scale construction; it is expensive to maintain and unmaneuverable. Automotive option able to drive to most objects;
• for stationary type units, special power supply is required; in construction conditions it can be difficult to create suitable conditions. In a concrete pump truck, power comes from the machine installation;
• a small pump has low performance, and the cost of installation is not affordable for all contractors. In terms of savings, renting a car unit is cheaper, and in addition it helps to complete the job many times faster;

Concrete pump – buy or make it yourself?

There are many offers on the used special equipment market, but first you should think about the feasibility of the purchase, because there is an option to make a concrete pump yourself. Basic skills will be required to create the installation. Homemade installations are less powerful and have a simpler design, but when properly manufactured they work properly and smoothly.

Initially, it is important to decide on the operating principle of the concrete pump: piston or hydraulics. The piston type is the simplest, but leads to rapid wear of the unit elements due to constant friction. Hydraulics are much better in performance, but are more difficult to manufacture. It is possible to make an automatic concrete pump, but they are less powerful.

Before starting to make a concrete pump with your own hands, important attention is paid to the gate - this is a kind of valve that ensures high-quality adhesion between the concrete pipe and the pump. The operation of the structure depends on the correct choice of gate.

How to make a concrete pump - production technology

During the work process you will need auxiliary tools, the desired measure is thermal insulation. A do-it-yourself gerotor pump is made according to a single scheme. Key points for assembling a concrete pump:

• Assessment of the feasibility of production. For large-scale construction, it makes sense to purchase your own installation. For small and medium volumes of work, it is profitable to rent a concrete pump. A homemade concrete pump is a relatively complex and expensive process.
• Creating a drawing. The concrete pump diagram is simple; its design will require minimal design skills or use existing diagrams. Do-it-yourself production is a more difficult method, but it allows you to create a design for specific needs. The use of ready-made diagrams is convenient due to the reduction in time costs and the ability to study reviews about the shortcomings of the drawing or find ways to improve the design in them.
• Selection of cylinder and piston. Key element systems should be selected with power reserves. The maximum cylinder diameter is 400 mm, it is better to choose smaller models. The piston stroke estimate is from 50 cm. If the parameters do not match, the number of working cycles increases, and as a result, rapid wear.
• Adjustment of piston and cylinders. In order for the pump to serve for a long time, it is necessary to perform high-precision fitting and eliminate roughness.
• Selection of node type. An electromechanical pump will help reduce the complexity and cost of manufacturing the device. The hydraulic option can be prepared manually, but this will increase costs and complicate the process.
• Gearbox installation. The mechanism must include a gear ratio to reduce and convert rotational movements into translational ones.
• Installation of the king pin. The element is connected to the mechanism. A metal corner is used to prepare the welded frame. The system incorporates alloy steel check valves and is wear-resistant.

After preparing the parts and assembling the pump, all that remains is to check the functionality of the installation. It is prohibited to start the device without concrete or a specialized starting mixture (manually made from cement with water and the addition of automobile oil).

Application of concrete pumps in construction

Monolithic high-rise buildings are almost always built using a concrete pump. The installations help deliver concrete to any floor with minimal time and physical costs.

With regard to private construction, the situation is somewhat more complicated, since access to the site for special equipment is limited, and manual preparation of the solution is an extremely lengthy procedure. Automotive installations are quite large; in working condition, the equipment takes up up to 12 m in width; the use of the boom requires more more space, up to 70 m. Mini concrete pumps will help eliminate the problem, simplifying the task and speeding up construction.

Order concrete with a concrete pump for small construction possible in combination with a KamAZ truck on which the line is fixed: 2 pipes with connecting clamps. An improvised concrete pump with a KamAZ truck is the largest version of a concrete pump.

If no truck arrives at the site, assembly must be done manually, but the participation of 2 or more people is required. Potential problems with manual installation:

• line rupture. There is a lot of pressure in the system, the clamps are not always able to withstand the pressure. Pulling out the fastener creates a hole. You will have to stop the system, clean the pipeline and make a more durable fastening;
• relocation of the highway. When changing jobs, it is necessary to move the pipe, but this cannot be done together with the solution. The lines will have to be disassembled, cleaned and reinstalled.

The long time it takes to set up the operation of the equipment is still significantly less than mixing the mixture manually.

Advantages of automatic concrete pumps

Production automatic installations have numerous advantages:

• There is a built-in electronic control unit that monitors the correctness and continuity of operation. The operator selects the operating mode, and the unit independently regulates the operation of the installation;
• independent flushing system for pipes and pump. Reduces time spent on maintenance and clearing congestion;
• lighting the surrounding area for working with the concrete pump after dark;
• sound alerts about major events;
• adjustment of gaps in the concrete distribution unit;
• all pumping units are supplied with a flushing system, special software and a concrete pipeline of up to 80 m;
• as an option, manufacturers offer a concrete distribution boom, which simplifies the delivery of concrete to the target location;
• full compliance of engines with EURO-4 standards;
• Reliable spare parts are used to increase durability and reduce maintenance costs.

The construction of even small structures requires the use of a variety of tools and techniques:

• The most common area of ​​use for a concrete pump is foundation formation. For the pile type it is convenient and cheap to use;
• at the core monolithic design A metal base is always used. will speed up the creation of the frame;

• Concreting is often combined with the use of other building materials. If the amount of work is large enough, it will be useful or;
• After erecting a structure, you always have to drill holes for electrical wiring, fixing equipment, etc. - it's simple and reliable way laying communications in the walls, the method is applicable for any other drilling work;
• at the final stage of arranging the building, it will be useful; with its help, the holes will be even, and a box for an outlet can easily be placed in them.

Conclusion

A concrete pump is a complex construction equipment that is not easy to make on your own, but if you have the skills and time, the work is quite doable. Manufacturing options are more functional and efficient, but are expensive. If you want to save money, you often rent a concrete pump.

The ever-increasing scale of construction stimulates the development of modern technologies that facilitate and speed up the work of workers. A variety of construction equipment appears on construction sites. One of the most popular equipment, especially in large-scale construction, is a concrete pump. Usage modern method the flow of solution significantly increases productivity and quality of work.

Features of application

A concrete pump is a difficult piece of equipment to use. Despite its productivity, the use of a concrete pump has certain features:

• attracting high-class specialists to the process;
• strict adherence to rules and technologies;
• responsibility in organizing and preparing the process;
• the use of special concrete solutions, taking into account the diameter of the hose for supplying the mixture; distance, conditions for supplying the solution to the building site.

Taking into account the peculiarities of using the equipment, it is easy to conclude that it is appropriate to use a concrete pump in conditions that are difficult or impossible to supply the mixture:

• access of equipment to the construction site is difficult;
• delivery of the solution to a high altitude is necessary;
• building density.

Of course, no one prohibits the use of a pump in favorable conditions. It all depends on the developer’s budget.

Types of equipment

Concreting of structures in different conditions requires the use of pumps different types. There is a huge selection of equipment suitable for transporting liquid solution. Three types of installations are most often used.

Stationary

The concrete pumping piston machine is located on a support with wheels. Used in long-term construction, construction of high-rise buildings. The equipment is installed for a long period of time and started by a gasoline or diesel engine. Using stationary equipment it is possible to:

• more than 4 meters;
• the speed of supplying the solution is 90 m³ per hour.

A stationary installation has its advantages:

• small sizes;
• Possibility of installation almost anywhere;
• rental cost is low.

Trailed

Mobile installation of low power. It is very convenient to transport and fits anywhere on the construction site.

Mobile

The equipment is secured to the support of a special truck. The advantages are undeniable:

• significant power allows the delivery of 150 m³ of solution per hour;
• , maneuverability;
• excellent performance, possible reduction in construction time.

The inconvenience of a mobile structure is its price. Large people can afford to buy such a car. construction companies. This option is not available to a private developer. The solution may be rent, which is calculated for 1 hour of labor or delivery of 1 m³ of solution.

Pump types

When working on a concrete pump, the principle of displacement is triggered; a volume is formed in the system, which can change. The process principle divides concrete pumps into:

• Piston (concrete is supplied continuously). Modern technology is capable of delivering concrete to a height of 6 to 65 m, the volume of solution supplied reaches up to 180 m³ per hour. Cement particles can get stuck between the rubbing surfaces of the pistons, so the piston type is subject to rapid wear. The solution flows in jerks. There is equipment with a hydraulic device. It is characterized by soft concrete delivery and high wear resistance. The feed speed does not change, and high pressure significantly increases the distance. The operation of two-cylinder units, unlike a machine with one, is so soft that it is almost unnoticeable.
• Gerotor (screw with continuous supply of solution). The technical capabilities of the gerotor design make it possible to silently supply concrete of any hardness. Possible blockage in the hose is eliminated by the ability of the motor to change the direction of rotation. Rapid wear of the hose for supplying solutions is the main disadvantage of the gerotor design, but this is compensated by the low cost of repairs, without the involvement of specialized personnel.

Practical experience in comparing two types of concrete pumps shows that despite the ease of repair of the gerotor design, the hydraulic piston device is more durable and more productive.

Moving concrete

Delivering concrete to a construction site is not an easy task. Incorrect actions can significantly damage the quality of the mixture. Problems can be prevented by using a concrete mixer truck. A concrete mixing structure is attached to the vehicle chassis. Inside iron barrel blades are welded. Rotating the barrel clockwise helps move the solution inward, and turning on the reverse process pushes the solution along the blades to the discharge hole.

Advantages of using a mixer:

• maintaining homogeneity, no stratification of the solution;
• constant movement of the solution, even with temporary delays, can preserve technical specifications composition.

The volume of the mixer barrel allows you to prepare or transport from 5 to 9 m³ of concrete mixture. To ensure that the finished product arrives at the construction site, the machine is equipped with a special loading tray. It is possible to use this type of transportation when the car can easily drive up to the construction site.

What to do when it is impossible to safely reach a built-up area? In this case, a pipeline is used, which belongs to special in-building equipment. Its technological advantages are undeniable:

• vertical, horizontal transportation using one mechanism;
• Easily reach hard to reach places.

Pipeline equipment - machines for supplying concrete or a separate type of construction equipment. The installation of separate equipment involves mounting a concrete pump on the base of a vehicle, using a full-rotating boom. This type of equipment allows you to transport the liquid mixture in a horizontal or vertical position for auxiliary structures.

Concreting floors in multi-story construction is impossible without the use of special equipment. The delivered solution is loaded via trays into the concrete pump receiver. Through a pipe consisting of three connected parts, the mixture is delivered to a height, to hard-to-reach places.
