Introduction of high-pressure injection pump

The pressure grouting method of high-pressure injection pump refers to the use of hydraulic pressure to evenly inject the solidified slurry into the filling formation. The slurry fills, infiltrates, and compacts, etc. to drive off the moisture and air between the soil particles and then fill it. After a certain period of time, the slurry cements the loose soil particles into a whole, thereby strengthening the soil foundation and reducing post-construction settlement.

First, the use of injection pump GZB-40C-type high-pressure injection pump for high-pressure rotary injection equipment, mainly for high-pressure rotary jet to provide high-pressure cement slurry. It is used to strengthen and reinforce weak foundations such as newly-built buildings, highways, high-speed railways, and underground railways, and is used for anti-seepage treatment around foundation pits, hydroelectric cofferdams, and dams for reservoirs.

Second, the characteristics of injection pump GZB-40C high-pressure injection pump is based on the original GZB-40A, GZB-40B gradually improved. Compared with similar products, its shaft-type transmission can avoid the sudden accident of the needle-type transmission, and the working life of the power end is extended; its thick crankshaft guarantees that no crankshaft breakage will occur; the hydraulic end is reasonable in structure and easy to disassemble. , The accessories are durable. It is a very mature and suitable high-pressure mud pump.
