Concrete Pump

 

a construction machine for the forced pumping of concrete mix through a conduit to the location where it is to be placed.

Concrete pumps are distinguished according to design (one- and two-cylinder) and type of drive (crank and hydraulic). In both types the plunger sucks concrete mix from the pump hopper while the delivery valve (gate) is closed and the suction valve is open; on the return cycle it ejects the mix into the conduit. Hydraulically driven concrete pumps have a longer plunger stroke in the working cylinder than do crank-driven pumps; they also have a constant plunger speed, which provides a steady, even movement of the concrete mix and reduces the resistance to movement of the mix in the conduit and the power requirements for the electric motors. In the USSR concrete pumps are manufactured with production capacities of 5, 10, and 40 m3/hr, feeding concrete mix up to 40 m vertically and up to 300 m horizontally. The equipment of a concrete pump includes a concrete conduit of separate pipes with quick-release connections.

There exist 2 main reasons of why concrete pump was chosen as a construction machine in this study: (i) it is inevitable to employ concrete pumps in construction projects including concrete-based products; (ii) it is a highly risky decision whether to purchase concrete pumps, requiring a great financial investment that can be measured with a million dollars.
