──Jun 04 , 2021What is high pressure rotary jet pile? Introduction of high pressure rotary jet grouting pile.

Technical principle:

High pressure rotary jet pileIt is a kind of high-pressure jet grouting method, which inserts the grouting pipe with a special nozzle into the designed soil depth, and then shoots the cement slurry from the nozzle in the form of a high-pressure jet to impact the cutting soil. The soil and cement slurry are stirred to form a mixed slurry, which then forms a continuous lap cement plus solid.

High pressure rotary jet pileThe basic process types include: single pipe method, double pipe method, triple pipe method and multiple pipe method.

superHigh pressure rotary jet pileMachines and tools can be supplied30MpaAbove the grouting pressure, cut and reinforce the formation formed by the pile diameter up to 2mThe above.

Micro turbulence jet grouting pile: using control jet grouting construction of formation pressure, through the sensor monitoring pressure and suction pulp mouth back to cooperate, will be in the process of rotary spray waste slurry and mud discharge, control the formation pressure within the design value, thereby reducing the disturbance of formation, but also increased the diameter of the jet grouting pile and pile strength.

Technical advantages:

(1) Construction machinery and equipment is light, construction movement is simple;

(2) Construction materials from a wide range of sources;

(3The construction occupies less land, has little vibration and low noise.
