摘要
在邻海地区富含高承压水的土层中施工预应力锚杆支护工程的难度很大。介绍了锚杆的构造、作用机理、施工工艺以及决定锚杆施工质量的关键技术。以深圳某商住楼基坑施工为例,探讨了在承压水土层中采用锚杆支护的方法,创造性地提出了“先堵水后注浆”的施工工艺,可供沿海、沿江地区的类似工程借鉴。
This paper introduces the structure, working principle, construction process of anchored bar and the most important factor affecting constructing quality of anchored bar. It is very difficult to construct prestress anchored bar in the area near sea that contains many highly confined aquifers. The paper discusses methods of anchored bar supporting in soil with confined aquifer and puts forward creatively constructing process of blocking up first and then grouting for a case of excavation, which can be refered by similar engineering located in the area near seas or rivers.
