Introduction of high pressure rotary jet grouting pile, high pressure rotary jet grouting pile construction technology

High-pressure rotary jet grouting pile 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 injected from the nozzle in the form of high-pressure flow to impact and cut the soil. Under the action of high pressure jet flow, the soil is destroyed, and the soil particles are spalling off from the soil layer and mixing with cement slurry to form a mixed slurry.

What is high pressure rotary jet pile? Introduction of high pressure rotary jet grouting pile.

High-pressure jet grouting pile is a kind of high-pressure jet grouting method. The grouting pipe with 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.

How to do foundation pit support? 8 kinds of common foundation pit supporting methods.

Foundation pit support is to adopt retaining, reinforcing and protecting measures for the side wall of foundation pit and surrounding environment to ensure the safety of the surrounding environment of foundation pit and the stability of soil, at the same time to ensure the construction of the underground structure of the building, to meet the requirements of basement construction with enough space. There are many forms of foundation pit support, each of which has its own advantages and disadvantages.

Introduction to SMW construction pile, what is SMW construction pile?

SMW is the abbreviation of the soil mixing wall, the construction method is also known as the steel cement soil mixing (pile) wall, is using multi-axis mixing pile machine in the project site one by one construction. The cement slurry or soil curing agent is spouted from the drill bit and mixed repeatedly with the foundation soil to form a continuous and complete underground wall with certain strength and stiffness without joints. Suitable for building foundation pit retaining wall, water curtain or soft foundation soil reinforcement.
