矿山法隧道防排水设计和施工若干问题探讨

为防止和减少矿山法隧道的渗漏水病害,应从防排水设计和施工方法等方面进行改进和创新,以不断提高隧道工程的防排水效果。本文从隧道防排水的设计原则、注浆防水、结构排水体系、防水层防水效果检验等多个方面,分析了存在的主要问题,提出相应对策,供类似工程参考。

Discussion on Waterproofing&Drainage Design and Construction Issues for Tunnels Constructed by Mining Method

To prevent and reduce the leakage danger of tunnels constructed by mining method,the waterproofing and drainage design and construction methods should be improved and innovated in order to enhance the waterproofing and drainage effect of tunnel projects constantly.This article,from the aspects of waterproofing and drainage design principles,grouting waterproofing,structural drainage system,effect testing of waterproofing layer et cetera,analyzes the main problems existed and puts forward corresponding countermeasures for reference of similar projects.
