组合式围堰在雷州青年运河灌区续建配套与节水改造工程中的应用

摘要

The comparison is made among three kinds of cofferdam construction scheme of lining project of Leizhou youth canal irri-gation channels. Combined cofferdam and construction method can make full use of steel, plywood, color of the cloth structure per-formance. Combined cofferdam retaining water diversion problem is solved, and the risk and difficulty of construction cofferdam are greatly reduced, also the cofferdam construction speed is accelerated, the total cost of the cofferdam is reduced. Construction experi-ence of combined cofferdam has been summarized, which providing the reference for the similar engineering combined cofferdam construction and arrangement of the technical problems.%对雷州青年运河灌区渠道衬砌工程中3种围堰施工方案进行对比，最后确定的组合式围堰及其施工方法能够充分利用槽钢、夹板、彩条布自身结构性能的特点，解决组合式围堰挡水导流问题，降低了围堰被破坏的风险和施工难度，加快了围堰施工速度，降低围堰总造价；总结组合式围堰的施工经验，为类似工程组合式围堰施工及布置等技术问题提供借鉴。
