自钻式高压旋喷工艺在止水帷幕中的应用

Application of Auto Rotation Type High Pressure Jet Grouting Technology in Waterproof Curtain

常规的高压旋喷工艺在砂砾地层中特别容易引起塌孔而导致效率低下和成桩质量下降,而采用自钻式高压旋喷工艺则解决了这个难题。自钻式高压旋喷工艺对处理淤泥、淤泥质土、黏性土、粉土、砂土、人工填土、碎石土等具有良好的效果。

Ordinary high jet pressure technology may cause hole collapse easily in the gravel stratum, resulting in low efficiency and poor bore quality. The problem can be solved by using auto rotation high pressure jet grouting technology. The paper describes the application of auto rotation high pressure jet grouting technology to treat silt, silt soil, clay, sandy soil, artificial fill, spall, and its good results.
