公路隧道防排水施工控制方法

Method on Water Control and Drainage of Road Tunnel

隧道施工期间防排水施工不达标,对于隧道后期运营以及隧道使用寿命存在很大的影响,且进行防排水处理难度大、费用高,效果差。本文以新七道梁隧道(下行线)为例,介绍了公路隧道防排水施工,铺设PVC复合土工布防水板工艺、排水管道施工等,希望对相关领域工程设计与施工实践等能起到一定的借鉴作用。

The construction of tunnel drainage which didn＇t reach the standard can cause a great influence on later operation and the tunnel＇s service life. And it is difficult, costly and ineffective in its treatment construction. Taking New-7th Dao-liang tunnel for example, the article introduces the construction of water control and drainage of road tunnel by laying PVC complex geotextile repelling board and drain line construction, which could serve as a reference for project design and practice.
