基坑螺旋钻孔灌注桩止水支护工艺的应用研究

摘要

Combining with the construction conditions and surrounding buildings of some project,the paper selects the waterproof support craft for the spiral drilling bored piles of the foundation pits,illustrates the construction techniques and precautions in the construction,avoid its damages for surrounding buildings and save construction cost by ensuring the construction quality,so as to shorten the construction time.%结合某工程施工条件及周围建筑情况，选用了基坑螺旋钻孔灌注桩止水支护工艺，阐述了其施工技术及施工中的注意事项，在保证施工质量的同时避免了对周围建筑物的破坏，且节约了施工成本，缩短了施工时间。
