高速公路隧道引水洞施工技术研究

Research on Construction Technology of Water Diversion Tunnel of Expressway Tunnel

在鄂西高速公路隧道运营过程中,庙垭隧道发生突水,大量积水从预埋洞室涌出,造成交通中断。为了保障隧道通行安全,决定平行于庙垭隧道新增一条引水洞用于排水。基于此,论文主要对隧道引水洞施工技术进行了探究。

During the operation of tunnel ofWest Hubei expressway,water inrush occurred inMiaoya tunnel,a large amount ofwater gushed out from the buried chamber,which caused traffic interruption.In order to ensure the safety of the tunnel,it was decided to add awater diversion tunnel parallel toMiaoya tunnel for drainage.Based on this,this papermainly explores the construction technology of tunnel diversion tunnel.
