Technical principle:

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

The basic technology types of high-pressure rotary jet grouting pile include: single pipe method, double pipe method, triple pipe method and multiple pipe method.

Super high pressure rotary jet grouting pile machine can be provided30MpaAbove the grouting pressure, cut and reinforce the formation formed by the pile diameter up to2mThe 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.
