龙口合龙是大型围堤工程的关键，尤其对于水流急、土质差的工况，能否一次性合龙直接关系到围堤大坝的安全。文章针对恶劣工况，创新采用构建扭王字块透水连续墙结合抛石的工艺，简化了合龙工序，降低了合龙风险，取得了较好的经济与社会效益。

Closure gap construction has played a key role in cofferdam project. Especially for the large flow velocity and soft soil property conditions, whether the closure gap can be smoothly closed in one time is related to the security of the entire cofferdam. Based on poor working conditions, we innovatively used accropodes diaphragm wall and rock rip-rap techniques, which can simplify the closure gap process, reduce the risk, and obtain good economic and social benefits.
