摘要
结合工程实例,介绍在裂隙和溶洞发育的岩溶地区,采用冲击反循环钻进、钢护筒护壁、压密注浆等工艺的冲(钻)孔灌注桩施工技术。
Combining practical projects,authors introduce the construction technology of punched and drilled grouting piles,which combines several construction method such as impulse reverse circulation drilling,steel cylinder protection and pressed grouting,and which can be used in karst areas having many rock cracks and cavities.This technology is a feasible and effective method for foundation construction of piles embedded on rock under similar geologic conditions.
