高速公路低瓦斯隧道施工技术及控制要点

Construction Technology and Control Points of Low Gas Tunnel in Expressway

隧道工程在公路工程建设中占有重要地位,在施工中,难免会遇到低瓦斯现象,若处理不当,则会影响施工安全,同时诱发一系列的安全事故,所以低瓦斯隧道怎样进行施工、如何进行有效排放瓦斯及监测瓦斯就至关重要。以贵州凯里环城高速公路项目洛邦隧道为例,对高速公路低瓦斯隧道的施工技术及控制要点进行介绍。

Tunnel engineering plays an important role in highway engineering construction.During construction,it is inevitable to encounter low gas phenomenon.Improper treatment will affect construction safety and induce a series of safety accidents.Therefore,how to construct low-gas tunnel,how to effectively discharge and monitor gas is very important.Taking Lobang Tunnel as an example,this paper introduces the construction technology and control points of low gas tunnel of expressway.
