摘要
反滤排水系统是边坡挡护工程的重要组成部分,如何在对既有边坡挡护工程进行加固的同时修复其反滤排水系统,需要进行研究。文章提出了一种用于既有边坡补强加固的兼具加固和排水功能的新型加固结构——排水锚杆,并阐述了排水锚杆加固既有边坡挡护工程的工作原理及构造——通过连接构件形成轴向可拆卸对接的排水管、锚固管,排水管管壁上分散开设排水小孔用于汇集地下水,在排水管外端部连接有用于锚固的外锚钢板,并提出了排水锚杆施工方法。
The inverse filter drainage system is an import part of slope retaining work. It pair the inverse filter drainage system when reinforcing the existing slope retaining work. is necessary to study how to re- In this paper, the drainage an- chor rod-a new reinforcement structure with the functions of reinforcement and drainage is put forward for reinforcement of existing slope and the structure and construction method of drainage anchor rod for reinforcement of existing slope re- taining work is described. The principle of the anchor rod is to form the axial detachably-butted drainage pipe and an- choring pipe by jointing element, open dispersedly the small drainage holes on the wall of drainage pipe to collect the underground water and connect the external anchor steel plate for anchoring at the external end of drainage pipe.
