摘要
在陕京输气管道穿越北拒马河工程中,采用了浮桶漂管法,成功地完成了此次穿越施工。指出在适宜的水文地质条件下可选用浮桶漂管法,并对其施工方法、施工程序及各程序的具体做法均作了较详细的介绍。该施工方法可缩短工期、降低造价,对于地下水位高、渗水速度快的砂卵石层河床优先推荐选用。
The pipe-floating method used to cross the North Jumahe River proved to be completely successful in Shannjing Gas Transmission Pipeline. It is pointed out that this method can be selected under the specific hydrogeologic conditions. The paper introduces in details the execution method,procedure and concrete operation of the pipe-floating river crossing construction. This method can shorten the crossing period and reduce costs. It is suggested that the method should be selected prior to the high underground water level and pebble-riverbed with high water permeability.
