南水北调中线一期穿黄工程南北岸连接渠道共有跨渠渡槽2座,跨渠桥梁7座,有6座跨渠建筑物桥墩与总干渠过水断面相交,总干渠采用PE复合土工膜防渗,桥墩与渠道相接部位防渗设计是本工程设计的难点,本工程设计采用KS胶粘剂并对桥墩局部位置进行特别设计,较好解决了桥墩与渠道相接部位的防渗问题。
There are 2 cross-channel aqueducts and 7 cross-channel bridges in the connecting channel of the South-North Water Diversion Middle Route Phase 1 project. There are 6 cross-canal bridge piers intersecting with the cross-section of the main canal. The PE composite geomembrane in the main canal is impervious to seepage, The seepage control design of bridge piers and channels connecting parts is the difficulty of this project design. The design of this project adopts KS adhesive and specially designs the local position of piers, which solves the problem of seepage prevention at the connecting parts of piers and channels.
