摘要
某36层建筑基坑最深17m，影响范围内有多条管线和建筑物，地下水位埋深7．40—8．70m。通过计算分析，采用循环钻机成孔大口径管井降水。施工实践证明降水井数量及布置满足地下工程施工需要。
The foundation pit of a 36-storey building is 17m deep and there are multiple pipelines and buildings within the influencing scope where the groundwater level depth is 7.40m to 8.70m. After calculation and analysis, circulation drill boring large-diameter pipe well dewatering technique is adopted. Construction practices show that number and arrangement of dewatering wells of such technique could satisfy the requirements of underground engineering construction.
