Staged diversion cofferdam construction method for rubber dam
The invention relates to the technical field of hydraulic engineering, in particular to a rubber dam staged diversion cofferdam construction method which comprises the following steps: (1) preparation work; (2) surveying and setting out; (3) earthwork backfilling and compacting; (4) geomembrane laying; (5) laying bagged soil; (6) removing the cofferdam; by the adoption of the staged diversion cofferdam construction method for the rubber dam, a large amount of construction cost is saved, meanwhile, compared with excavation of diversion ditches, the water cross section is large, safety is higher, and the earthwork excavation and backfilling amount is reduced; and meanwhile, construction is completed before drainage of the upstream of the river channel, reworking is avoided, the cost of cofferdam filling and dismantling, site dewatering, cleaning and the like is saved, the construction period can be effectively shortened in flood control projects with high construction period requirements, and great significance is achieved for the whole project.
本发明涉及水利工程技术领域，具体涉及一种橡胶坝分期导流围堰施工方法，包括：(1)准备工作；(2)测量放样；(3)土方回填压实；(4)土工膜铺设；(5)袋装土铺设；(6)围堰拆除；通过采用本发明提供的橡胶坝分期导流围堰施工方法，节省了大量的施工成本，同时与开挖导流沟相比过水断面较大，安全性更高，减少开挖回填土方量；同时在河道上游放水前施工完成，避免了返工，节省了围堰填筑、拆除和场地降水、清理等费用，在对工期要求紧的防洪工程中能有效缩短工期对整个工程具有重要意义。
