High pressure jet grouting pile technology

High-pressure jet grouting pile is a kind of high-pressure jet grouting method. It inserts a 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 and cut the soil. . The soil and cement slurry are stirred to form a mixed slurry, which then forms a continuous overlapped cement and solid.

The basic process types of high-pressure jet grouting piles are: single-tube method, double-tube method, triple-tube method and multiple-tube method.

The ultra-high pressure jet grouting pile machine can provide a spray pressure of more than 30Mpa, and the diameter of piles formed by cutting and strengthening the ground can reach more than 2m.

Technical advantages:

(1) The construction equipment is light and easy to move;

(2) Extensive sources of construction materials;

(3) The construction area is small, the vibration is small, and the noise is low.
