Concrete Pump

Pumping starts with the pouring of concrete from the ready mix truck into a tank large enough to hold a small amount of fresh concrete. In the mixing drum, the mixer allows fresh concrete to flow smoothly into the pumping cylinder. Concrete piston pump works on the same principle as a twin piston engine in which a cylinder removes concrete from the cylinder on its rotational stroke. And another is pushed into the line The pistons in both cylinders work in opposite directions, so there is constant pressure on the concrete in the line and in continuous flow. The piston operated hydraulic cylinder is driven by the hydraulic pump. The synchronization valve holds the concrete from two cylinders to a drain pump. This valve is often used to separate one pump type from another. Some common types of valves are rock gate, rotary ball pipe or C pipe.

Frequently Asked Questions (FAQ’s)

Q: What kind of pump does concrete use?

It is known as a concrete ■■■■ pump because it uses a remote control dovetail robotic arm. (Called the ■■■■) to place the concrete precisely. ■■■■ pumps are used in most large construction projects because of their ability to pump very high volumes and the labor-saving nature of the placing ■■■■.

Q: How does a concrete pump work?

Concrete pump is a vehicle for transporting liquid concrete.

For more than half a century, concrete pumps have been gradually adopted by other transfer methods of liquid concrete. Several concrete pump designs were developed in the first half of the 20th century, but Friedrich Wilhelm Schwing’s company Schwing GmbH invented the double-cylinder hydraulic concrete pump in 1957, the principles of this design were given. Certifications from almost all other manufacturers and continues to be a design that meets world standards

Pump operation demonstration The pump pulls the liquid concrete from the tank into the cylinder with one piston while the other pushes the concrete into the drain at the same time. The valve, which determines which cylinder opens to the concrete cylinder and which opens to the drain pipe, is changed every time the piston reaches the end. (See the stone hatch below and animation on the left - click to enlarge) and the process will continue. The first cylinder empties and the second cylinder draws fresh concrete from the tank.

While craning concrete in the construction of high-rise buildings, concrete pumps were of great importance in the construction revolution of large buildings. Previously, a crane was used to lift (or cross) large tanks filled with concrete to the point of need. The crane can lift one bucket at a time, usually about 2 yards of concrete.

This concrete pump has many advantages over bucket and crane system. In addition to being able to pump concrete much faster than the bucket can handle, it means a continuous supply of concrete on top, and laying pipes can be placed wherever needed to keep the concrete liquid. It can be poured directly from the pipe. When necessary, without having to lay two cubic meters of concrete in the desired area

Q: How far can a concrete pump truck reach?

About 150 meters
The ground line hydraulic pump can change the concrete at a rate of 1 m3 per minute and can be extended up to about 150 meters to reach the pouring location.

Q: Is the pumped concrete weaker?

It has been believed for many years that the pump mix will soften as it has to be mixed with less coarse sand and more sand and maybe a little more than cement and mixing would be better.

Q: How does a concrete pump work?

The science behind concrete pumping

It works by means of a valve system and basic principles of hydraulics. When concrete is needed, the concrete mixer truck first mixes the concrete inside the rotating drum.The truck will then pour the liquid concrete into the tank, which will continue to rotate the concrete so that it does not solidify.

Q: How much money can you make with a concrete pump?

How much does a concrete pump operator earn in the USA? Concrete pump operators in the United States earn an average of $43,086 a year or $20.71 per hour. People at the bottom of this spectrum earn about $26,000 per year, while the absolute bottom 10% earn about $70,000 a year.

Final Verdict

We hope that all your answers about concrete pumps and their types are now clear. Concrete pump trucks help make construction projects easy and efficient by efficiently transferring concrete from one place to another. If you are in a large construction project then using a ■■■■ pump would be the best option and a line pump would be the right choice for a small construction project.

A line pump gives you more flexibility as you can deliver concrete in locations that are inaccessible. You can save more when you use a line pump instead of a ■■■■ pump. Make sure you always hire a professional concrete service to get the most out of your construction project.

So it is now clear when to use a line pump and when to use a ■■■■ pump. Let’s make the next project more advanced and efficient.

Pump priming

Concrete pumps are instruments used to transport newly mixed liquid concrete to the appropriate area on a building site. Before concrete pumps, builders had to have buckets of concrete lifted by cranes; now, concrete may be pumped up to the topmost levels.

What Exactly is a Concrete Pump?

A concrete pump is a machine that uses pumping to move liquid concrete. Concrete pumps are classified into two categories.

:black_small_square: The first type of concrete pump is mounted on a truck, while larger units are mounted on semi-trailers. It is known as a resonance concrete pump because it correctly places concrete using a remote-controlled articulating robotic arm (called a resonance).

:black_small_square: The second most frequent form of concrete pump is a line pump or trailer-mounted concrete pump, which is either installed on a truck or placed on a trailer. This pump necessitates the hand attachment of steel or flexible concrete laying hoses to the machine’s outlet.

History of Concrete Pump

Until the early twentieth century, concrete was mixed on the construction site and delivered in wheelbarrows or buckets lifted by cranes from the cement mixer to the formwork.

This took a significant amount of time and effort. Max Giese and Fritz Hull, two German engineers, invented the idea of pouring concrete through pipes in 1927.

They poured concrete to a height of 38 meters (125 feet) and a length of 120 meters (130 yd). Shortly after, Jacob Cornelius Kweimn patented a concrete pump in Holland in 1932. (Jacobus Cornelius Kooijman). The developer’s earlier German patent was included into this invention.

Mechanism of Concrete Pump

Because concrete is heavy, viscous, abrasive, includes particles of hard rock, and hardens if not maintained flowing, concrete pump designers confront several obstacles.

The Piston pumps are commonly utilized because they can generate hundreds of atmospheres of pressure. These piston-style pumps can move cylinders containing heterogeneous concrete mixtures (aggregate + cement).

How Concrete Pumps Operate

A concrete pump operates on the basis of a valve system and fundamental hydraulic principles. The concrete pump draws liquid concrete via a valve system and into the area where it has to be placed down after a mixing truck pours liquid concrete into a hopper.

Material Quantity in Kg/M³
M-20 M-25
Cement 320 360
Fine Aggregate 862 847.5
Coarse Aggregate 1097 1077.50
05 mm 438.8 430.83
20 mm 658.2 646.67
Water 188.8 205.2
Admixture 2.56 5.41

Most concrete pumps will also include a twin-cylinder hydraulic system, which is made up of two parallel cylinders. The first cylinder is referred to as the material cylinder. It draws concrete from the hopper. The discharge cylinder, which pushes concrete out of the pump, is the second.

Line pumps typically pump concrete at lesser volumes than resonance pumps and are utilized for lower volume concrete placement applications such as swimming pools, walkways, single family dwelling concrete slabs, and most ground slabs.

There are also skid mounted and rail mounted concrete pumps, however they are unusual and primarily utilized on specialist job sites like mines and tunnels.

Summary

Concrete pumps are becoming commonplace on construction sites because they improve the efficiency of construction projects, particularly those involving high-rise buildings.

Concrete Pumps of Various Types

Various types of Concrete pump are as follows:

:one: Pumps on Wheels

Pumps on Wheels

This pump is made up of a concrete pump and a placement resonance installed on a truck chassis. The benefit of employing this pump is that the resonances can be adjusted in size, allowing concrete to be pushed swiftly to any point within the resonance range.

:two: Pumps that are stationary

Pumps that are stationary

This pump is installed on a trailer, and concrete is transported to the site via a separate pipeline that is also linked to the trailer. The pipe is then linked to a putting resonance for accurate placement of the concrete.

:three: Static Pump on a Truck

Static Pump on a Truck

A static or stationary pump is positioned on a truck bed, but it lacks placement resonances, so workers must use separate placing hoses to transfer the concrete to the proper location. These are ideal for rapid projects since they can be driven immediately to construction sites.

:four: Concrete Pump Truck Mixer

Concrete Pump Truck Mixer

This is an all-in-one type that includes a concrete mixer and a pump. As a result, both mobile and static pumps will have a huge hopper from which to draw concrete.

The Technology Behind Concrete Pumping

:black_small_square: A concrete pump is a gadget used to transport newly mixed liquid concrete to the desired position on a building site. It operates on the basis of a valve system and fundamental hydraulic principles.

:black_small_square: When concrete is needed, a mixing truck first mixes the material within its revolving drum. The truck then drops its liquid concrete into a hopper, which continues to churn the concrete, preventing it from solidifying.

:black_small_square: The concrete pump then draws the liquid concrete out of the hopper, through a valve system, and into the area where it will be placed down, often with the help of auxiliary hoses.

:black_small_square: The internal workings of a twin-cylinder hydraulic concrete pump are normally made up of two parallel cylinders. Inside the cylinders are driving pistons that propel them back and forth in opposite directions.

:black_small_square: As one cylinder advances, the other recedes. As one cylinder recedes, the other advances.

:black_small_square: The first cylinder, also known as the material cylinder, is responsible for pulling concrete from the hopper. The second cylinder, the discharge cylinder, pushes the concrete from the pump to the desired spot.

:black_small_square: The two pistons function in unison, drawing in and pushing out their respective quantities of liquid concrete. The two cylinders alternate back and forth due to the hydraulic flow caused by the continuous flow of concrete. This constant flow is also necessary to prevent the liquid concrete from hardening.

Summary

Concrete pumps are employed on the majority of bigger construction projects due to its ability to pump at very high volumes and the labor-saving nature of the placement resonance. They are a game-changing alternative to line-concrete pumps.

Concrete Pump Common Applications

Concrete pumps may be used in a wide range of construction applications.

:small_blue_diamond: Slab building foundations: The foundations of buildings that do not have basements are flat slabs of concrete. It is critical to have a stable foundation that will not leak, break, or droop.

Concrete pumps are essential for ensuring that the task is completed swiftly and efficiently, and that the concrete is placed exactly where it should be. In this manner, no flaws in the foundation may arise.

:small_blue_diamond: Building foundations with basements: The procedure of establishing the foundation for structures with basements is more involved.

Concrete pumps, such as resonance pumps, are essential to ensure that there are no time delays during which mistakes can occur or portions of the concrete solidify before they are ready.

The use of resonance pumps for basement foundations aids in the completion of the building project on schedule.

:small_blue_diamond: High-rise structures: Because of the elevation and reach it gives, a resonance pump is frequently required for high-rise buildings. Resonance lifts allow construction companies to rapidly, efficiently, and safely pump concrete to upper levels while keeping the building process on time.

:small_blue_diamond: Highway overpasses and tunnels: To handle the daily tonnage of traffic that passes over them, highway overpasses must be composed of robust, reinforced concrete.

Roadway tunnels must also be robust enough to withstand the weight of the ground above them. Using a concrete pump ensures that the operation is completed swiftly and successfully.

Overpasses and tunnels sometimes need working at an elevation, and the use of a concrete pump, particularly a resonance pump for its increased lift, makes the operation go faster and simpler.

:small_blue_diamond: Bridges and dams: Bridges and dams must be huge, sturdy, and stable in order to withstand the weight of heavy vehicle traffic and high water pressure. Resonance pumps, in particular, have the benefit of allowing concrete to be pumped swiftly to the top of a tall bridge or dam due to their lift and extension.

:small_blue_diamond: Parking structures: Parking garages typically have many levels, and it is difficult to move concrete to the top levels without a concrete pump. The use of a concrete pump allows the building of a tall parking structure to be finished swiftly and with minimal waste.

:small_blue_diamond: Sidewalks and driveways: When building a new home, many homeowners are primarily concerned with the house itself. However, the sidewalk and driveway are also important components. Some homeowners are tempted to pour their own driveways and sidewalks, but hiring a professional construction business with a concrete pump, such as a resonance pump, is frequently the best chance for a smooth, sturdy, and fully cured driveway and sidewalk.

:small_blue_diamond: In-ground swimming pools: An in-ground swimming pool, like a basement, has a concrete foundation. Concrete pumps, particularly resonance pumps, have a distinct edge when it comes to the construction of backyard swimming pools.

No one likes a huge truck driving through their back yard, but a resonance pump can easily reach over the house from the street and pour the concrete with no inconvenience.

:small_blue_diamond: Patios and garden shed foundations: Just like backyard swimming pools, patios and garden shed foundations are ideal for concrete pumps such as resonance pumps. Resonance pumps can easily reach into the backyard from the street and quickly pour the concrete slabs for these features.

:diamond_shape_with_a_dot_inside: How Concrete Pumps Affected the Construction Industry?

:small_blue_diamond: The usage of concrete stretches back to Roman times — both the Colosseum and the Pantheon include substantial amounts of concrete — but pouring concrete was a labor-intensive process until the early twentieth century, when the concrete pump was invented.

:small_blue_diamond: Concrete pumps have been a huge boon to the building sector. Consider a construction worker in the early 1900s hauling a wheelbarrow full of concrete, making trip after trip after arduous, sweating journey until he had finally poured the project’s tiny amount of concrete.

:small_blue_diamond: This procedure is inefficient, labor-intensive, and time-consuming. The concrete pump makes transporting concrete considerably easier and faster.

:small_blue_diamond: Concrete pumping vehicles have been especially influential in high-rise construction. Cranes had to hoist huge buckets of concrete into the air onto higher floors before the advent of the concrete pump.

Because a bucket only stores a limited amount of concrete, this method was inefficient. Modern concrete pumps can pump concrete quicker than cranes can lift buckets and provide a constant supply of concrete. They also allow concrete to be poured straight from a laying resonance rather than being sloppily moved in a bucket.

Summary

A concrete pump may be put up fast and operated by a minimal number of people. All of these characteristics combine to make concrete pumps indispensable user-friendly, efficient, and time-saving elements on any construction site today.

Frequently Asked Questions

People usually ask many questions about Concrete pump. A few of them are discussed below:

1. What does it mean to pump concrete?

Pumped concrete is concrete that is moved to greater heights by the use of concrete pumps. This approach is employed when there is a big amount of concrete work to be done at a higher elevation and other modes of transportation are not readily available.

2. Is it possible to pump concrete through a house?

The concrete pump pipeline can be simply routed through the front door, the interior of the house, and out into the yard - with minimal disturbance and trouble. The same is true for other difficult-to-access regions, such as basements and sites with tiny entrances and down alleyways.

3. Is it possible to pipe concrete?

Yes, by employing long-reach pipes, a concrete pump allows you to reach locations that require concrete placement. It saves time and decreases labor requirements, making it more cost efficient.

4. Is concrete harmful to PVC pipe?

Small surface fractures would have no effect if the pipe was completely enclosed in concrete. If the fractures extend all the way through, as in a foundation crack, the pipe may be damaged. The pipe will be destroyed if the concrete shifts along the crack line.

5. Is it possible to pour concrete over plumbing?

No, Never pour concrete on PVC conduit or water pipes unless they are wrapped in a form wrap to allow for expansion and contraction and any perforation through the concrete, or unless a 4in or 6in sleeve is installed under the slab to enable the pipes to pass through.

Conclusion

Concrete pumps provide several more advantages. Because they work continually, they can pump large amounts of concrete at once. Because the concrete is continually flowing, personnel are never idle, never standing around waiting for it to come by other means.
