摘要:

河北省某铁矿竖井采用钻井法施工，拆除井筒钢护壁后出现井筒漏水。先后采用井内填土、井底注浆，横向钻孔、壁后注浆，砌筑混凝土止浆墙等治理措施，最终达到了止漏的目的。

Abstract:

An iron ore shaft in Hebei was constructed by drilling. After removal of steel casing in the shaft, water leaked around the shaft wall. Several methods, such as filling the shaft with mud, slip casting on the bottom of shaft, lateral drilling and slip casting behind the wall of the shaft and laying an water leakage wall, were take to stop the leakage. Finally the water was blocked.
