重庆歇马隧道ZK7+292涌水处治施工技术

The Water Burst Treatment Technique for ZK7+292 of Chongqing Xiema Tunnel

随着高速公路、铁路等大规模基础设施的建设,在复杂地质条件下修建的隧道工程也越来越多。在施工过程中,注浆法是一项必备的辅助工法,常用于处理隧道内突泥、涌水、软弱岩层等复杂地质,为隧道安全、顺利地掘进提供有力保障,同时,也保护了地下(表)水生态环境。论文结合重庆市歇马隧道工程实例,介绍了山岭隧道超前帷幕注浆施工中的关键技术,为同类工程施工提供技术参考。

With the construction of highway, railway and other large-scale infrastructure, in the complex geological conditions of the tunnel construction is also more and more. In the construction process, grouting is an essential auxiliary method, which is often used to deal with the complicated geology such as burst mud, gushing water, weak rock strata in the tunnel, provide a powerful guarantee for the safe and smooth tunneling. At the same time, also protected the underground(surface) water ecological environment. This paper combined with the example of Chongqing Xiema tunnel, introduced the key technology of advanced curtain grouting construction of mountain tunnel, and provided the technical reference for similar project construction.
