摘　　要：由于使用绞吸式挖泥船对水下充填袋围堰拆除时普遍存在袋布缠绕绞刀现象,使得拆除工作难以寸进,施工难度大,严重影响船舶施工效率,无成功经验借鉴。为解决上述问题,通过研究挖掘方式和工程的适用性,此次对铰刀进行设计改进,充分解决了这一难题,极大程度上提高了功效,可为类似工程提供参考。The reamers are always entangled with geotextile while cutter suction dredgers are used to dismantle a cofferdam built with underwater sand bags, which results in great construction difficulty and much lower efficiency. Due to no successful experience to be referred to, the dismantling way and its applicability are studied, and the design of reamers is improved, which solves the problem, raises the efficiency greatly, and provides a reference for similar projects.
