论可回收预应力锚索在基坑支护中的应用研究

Research on the application of recoverable pre-stressed anchor cable in the foundation pit support

深基坑支护工程中预应力锚索技术应用较多,但锚索若永久残留在地下,将给后续临近建筑物的施工带来困难,影响地下区域的开发建设。基此,文章结合工程实例,探究可回收式预应力锚索工作机理及其工艺特点,总结分析质量控制要点。实践证明,采用可回收式预应力锚索基坑支护技术安全可靠,回收工效高,对周边环境影响小,节约环保,具有推广价值。

There are many applications of pre-stressed anchor cable technology for the deep foundation pit on construction site.But if the anchor cable were permanently left underground which brings difficulties to the subsequent construction of nearby buildings and affects the development and construction of underground areas.Base on this reason,this article explores the working mechanism and technological characteristics of the recoverable pre-stressed anchor cable.Practices have proved that the use of recyclable pre-stressed anchor cable foundation pit support technology is safe and reliable.It brings high recycling efficiency and small impact on the surrounding environment.This technology has promotion value.
