西气东输延水关黄河隧道工程注浆堵水施工

Watertight construction by grout injection of Yanshuiguan tunnel works passing through Yellow river of West-East Gas Transport project

随着科学技术的发展 ,很多特大型穿越工程已经越来越多地采用隧道方式。但在大型河流下进行隧道挖掘施工 ,涌水处理的方法仍为难点。涌水处理主要根据设计文件中关于隧道可能出现涌水地段的涌水量的大小、补给方式、变化规律及水质成分的资料 ,结合工程实际情况因地制宜 ,选择既经济合理 ,又能确保围岩不受破坏 。

Along with the development of science and technology, the tunnel scheme is more and more used in large type of crossing works. But, the water springing treatment is still a difficult issue for the tunneling construction under large river. The water springing treatment scheme which is not only economic and reasonable but also does no damage to the surrounding rock and meantime is up to the requirement of environment protection should be selected in accordance with the quantity, supplement mode, variation law and component of springing water at possible sites inferred by design document and practical condition.
