深厚砂层地区管桩用于基坑支护的探讨

Study on the Application of Pipe Pile in Foundation Pit Support in Deep Sand Layer

以佛山市某工程基坑施工为例,通过预应力管桩结合扩大头预应力锚索进行支护,验证了7m深基坑支护采用管桩支护的可行性,并且采用管桩支护可提高工程速度,降低造价,对深厚砂层地区的类似基坑工程具有借鉴作用.

Taking the construction of a foundation pit in a project in Foshan as an example,the feasibility of using pipe piles to support 7m deep foundation pit is verified by combining prestressed pipe piles with extended prestressed anchor cables.The application of pipe pile support can improve the project speed and reduce the cost,and it can be used for reference for similar foundation pit projects in deep sand layer areas.
