【摘要】 樟涧水库除险加固过程中,临时围堰施工时遇到较深的淤泥质流砂土层,围堰的设计与施工无法完全满足规范要求.经方案比较,采用挤压法施工临时围堰,不仅施工进度快、运行安全,而且满足了工程工期要求.同时又降低了施工成本,可供类似工程参考.更多还原

【Abstract】 The deep silt sand soil was encountered in constructing temporary cofferdam for Zhangjian Reservoir Reinforcement Project. The design and construction of the cofferdam cannot fully meet the requirements of specification. By scheme comparison,the extrusion method is adopted to construct temporary cofferdam. It has the characteristics such as fast construction progress and safety operation. It meet the requirement of time limit for the project and reduce construction cost. It can be referred for similar projects.更多还原
