浅谈浅埋富水膨胀土隧道施工止水技术

On the Waterproofing Technology in the Construction of Shallow Buried Expansive Soil Tunnel

在隧道施工过程中,地质条件是影响施工进度和质量的重要因素。因此,在施工前充分考虑地质条件,采用合理的施工方法尤为重要。结合皂树岭一号、二号两座隧道施工,提出深孔注浆堵水的方法及施工注意事项,对今后类似工程的施工具有指导意义。

In the process of tunnel construction,geological conditions are important factors affecting the construction progress and quality.Therefore,it is particularly important to fully consider the geological conditions and adopt reasonable construction methods before construction.Combined with the construction of the No.1 and No.2 tunnels in Zaoshuling,the method of blocking water in deep hole grouting and construction precautions are proposed,which will be instructive for the construction of similar projects in the future.
