RJP constrution methods

1. Overview of constrution methods 

RJP is called double high pressure rotary jet engineering method, which is a new high pressure rotary jet engineering method with high construction efficiency and small disturbance to the surrounding environment . RJP construction method mainly lies in that it has carried out two cuttings on the stratum, the first is the ultra-high pressure water injection in the upper section, the space caused by cutting can smoothly discharge mud with the effect of releasing internal pressure, and the second is the ultra-high pressure hardened materials and air injection in the lower section, which further effectively cuts the soil layer and forms consolidated pile.

The supporting drilling tools of RJP engineering method are divided into nozzle body, spiral jet triple pipe/swing jet triple pipe, flow diverter and so

on.Our company has successfully obtained the national utility model patent authorization.
