加筋旋喷桩在基坑支护中的应用

Reinforced Chemical Churning Pile Application in Foundation Pit

高压旋喷桩常用于基坑截水帷幕,现通过在旋喷桩内置无缝钢管的方式来增强旋喷桩体的抗弯能力,使其同时达到止水和支护的功效。通过实际工程应用对该支护形式的特点及施工技术进行了阐述,为类似基坑支护设计和施工项目提供一定的借鉴。

The chemical churning pile is often used in the cutoff curtain.It is now used to enhance the anti-bending capacity of the pile by means of the seamless steel tube inside the chemical churning pile,so as to achieve the effect of stopping water and supporting.The characteristics and construction technology of this support form are expounded through practical engineering application,which provides reference for similar projects.
