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 flow to impact the cutting soil. The soil and cement slurry are stirred to form a mixed slurry, forming 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.
Advantages of process:
(1The construction machinery and equipment are simple and easy to construct.
(2) has good durability, and the material source is broad, low price.
(3The construction occupies less land, has little vibration and low noise.
