Concrete choice depends on the amount of work. For example, concrete pump, capacity 10 m3 / h is used in the volume of concrete not less than 1500 m3, 20 m3 / h - 4000 m3 and 40 m3 / h - 10 000 m3. The installation consists of concrete, with a hopper vibroreshetkoy, which does not allow to take concrete and Delivery line large particles aggregate concrete. Pump power is chosen [...]
Concrete Delivery line with the system and are useful for Pneumatic supply concrete to inaccessible areas of concreting in construction with gustoraspolozhennoy valves, narrow and long structures with large areas of concentrated volume of concrete. Concrete coverage of 300 m horizontally, vertically, - 40 m. In the Soviet Union used mainly single-cylinder piston pumps makes the C-252, BN-5, [...]
The use of belt conveyors useful for concreting facilities located close to the concrete plant. The concrete mixture from the dispensing tank mixing plants fed to main conveyor, which connects with the transverse light mobile or transportability transporters located in the area of concrete work, which is produced by the distribution and laying of concrete. Conveyors can be used in combination with dump trucks, concrete pumps and vibrating feeders. [...]
