摘要
介绍了广西北海市合浦县总江水闸除险加固工程的基本情况。对"膜袋充砂围堰+钢板桩防渗心墙"和"土石围堰+高压旋喷灌浆防渗心墙"全断面围堰施工导流方案进行了综合比较。结合总江水闸挡河闸坝施工导流实践,论述了膜袋充砂围堰+钢板桩防渗心墙全断面围堰施工导流的施工方法。
An introduction was made on the general information of Zongjiang Water Gate Reinforcement Project at Hepu County, Beihai City of Guangxi. Two full-section cofferdam diversion alternatives were compared. The determined scheme incorporates cofferdam constructed by membrane bag filled with sand and steel piling impervious core. Another alternative incorporates earth-rock cofferdam and high pressure jet grouting impervious core. Combined with the construction diversion practice at Zongjiang water gate, the author discussed the construction methods of the determined scheme.
