Comprehensive pipe gallery foundation pit supporting method for weathered rock stratum area
The invention belongs to the technical field of foundation pit supporting, discloses a comprehensive pipe gallery foundation pit supporting method for a weathered rock stratum area. The method aims to solve the problems that a foundation pit in the weathered rock stratum area cannot be embedded and fixed by adopting a steel sheet pile, and construction cost is high due to the fact that a dewatering well or a waterproof curtain needs to be constructed independently by adopting a row pile independently. The method comprises the following steps that (1) a hole is formed in the weathered rock stratum through rotary digging; (2) cement soil is poured into a pile hole; (3) a steel sheet pile is driven into a cement soil pile formed by the poured cement soil; (4) the earth of the foundation pit is excavated until the foundation pit meets the design requirements; and (5) the foundation pit is backfilled, and the steel sheet piles are recycled.
本发明属于基坑支护技术领域，公开了一种用于风化岩层地区的综合管廊基坑支护方法，为了解决在风化岩层地区的基坑采用钢板桩无法嵌入固定以及单独采用排桩需要单独施工降水井或止水帷幕而导致的施工成本高的问题。本发明方法包括：（1）在风化岩层中旋挖成孔；（2）在桩孔中浇筑水泥土；（3）向浇筑的水泥土形成的水泥土桩内打入钢板桩；（4）基坑土方开挖直至基坑满足设计要求；（5）基坑回填，并回收钢板桩。
