Classification and application of concrete pumps
Concrete pumps are indispensable equipment in modern construction, mainly used to transport concrete to high or far places. According to the working principle and structural characteristics, concrete pumps are mainly divided into the following types, each of which is suitable for different construction scenarios and needs.
1. Piston concrete pump
The piston concrete pump is the most common type, which sucks in and squeezes out concrete through the reciprocating motion of the piston. Its advantages are high delivery pressure and long delivery distance, which are suitable for large projects such as high-rise buildings, bridges and tunnels. According to the power source, piston concrete pumps can be divided into electric and diesel drives.
2. Extrusion concrete pump
The extrusion concrete pump uses the rotation of the extrusion roller to squeeze the rubber hose to push the concrete out. It has a simple structure and is easy to operate. It is suitable for small and medium-sized construction projects and short-distance delivery. However, its delivery pressure and distance are relatively limited, and it is not suitable for large-scale construction.
3. Screw concrete pump
The screw concrete pump pushes the concrete forward through the rotation of the spiral blade, and has the characteristics of good delivery continuity and stable pumping pressure. It is suitable for occasions where continuous concrete delivery is required, such as underground projects and tunnel construction. Screw concrete pumps have high requirements for the fluidity of concrete.
4. Truck-mounted concrete pumps
A truck-mounted concrete pump is a concrete pump installed on a car chassis. It has good maneuverability and flexibility and is suitable for construction projects that require frequent site transfers. Its delivery height and distance can be adjusted according to the vehicle model and configuration, and is widely used in urban construction, road construction, and bridge construction.
5. Trailer concrete pumps
Trailer concrete pumps are usually installed on trailers and need to be towed and moved by other vehicles. It has a simple structure and low cost, and is suitable for small and medium-sized projects and short-distance delivery. Trailer concrete pumps are easy to operate, but require additional traction equipment.
Conclusion
Different types of concrete pumps have their own advantages in construction. Choosing the right type of concrete pump can improve construction efficiency and reduce construction costs. With the development of the construction industry, the technology of concrete pumps is also constantly improving, providing more efficient and reliable solutions for various engineering projects.
