改进式高压旋喷防渗墙在砾石土坝的应用OA

In view of the high permeability of gravel soil dams,this paper proposes the use of high-pressure jet grouting for seepage prevention,utilizing-pressure cement slurry instead of high-pressure water to cut the surrounding soil,forming a sealed cement-filled chamber in advance.This effectively controls the overflow of subsequent low cement slurry,solving the problem of multiple re-grouting in the traditional triple-tube method,saving the amount of cement used for grouting,and improving grouting efficiency.
