多支护形式在复杂环境深基坑中的应用

Comprehensive Application of Multi-support Structure in the Deep Foundation Pit with Complicated Surroundings

介绍了某深基坑的施工,根据场地周边不同条件分别采用不同支护方案的设计施工要点。支护桩、水泥土墙、高压喷射注浆止水帷幕、深层搅拌桩止水帷幕、挂网喷护和井点降水等多种支护手段的综合利用,降低了成本,缩短了工期。

The design and construction essentials of the different support structures are adopted according to the different field conditions of the deep foundation pit with complicated surroupdings, such as retaining pile, cement-soil wall, waterproof wall with high pressure jet grouting, waterproof wall with deep mixing pile, wire-netting shotcrete, well-point dewatering. The comprehensive application of these different support structures is helpful to lower costs and shorten time.
