摘要
采用单袋叠筑法封堵龙口闭气施工,可确保龙口封堵一次性成功,避免了因封堵龙口失败所造成的重大经济损失,降低了施工风险。本文以余姚市海塘除险加固治江围涂二期工程小曹娥块、曹朗北块围涂工程为例,详细介绍了单袋叠筑法具体的施工准备、操作要点以及质量和安全控制措施,供其他类似工程参考。
Single bag staking method is adopted for closure gap sealing water tightne6s construction, which can ensure one- time success of closure gap sealing, thereby avoiding significant economic losses due to failure in sealing closure gap, and lowering construction risk. Xiaocao＇e block and Caolangbei block reclamation works in Yuyao seawall risk removal reinforcement river control reclamation stage II project are adopted as example in the paper. Concrete construction preparation, operation essentials as well as quality and safety control measures for single-bag stacking method are introduced in detail, thereby providing reference for other similar projects.
