预制墩台湿法安装是一项全新的施工工艺,止水技术是其关键控制要素,分离式胶囊柔性止水是对原设计整体式胶囊止水工艺的优化改进,试验研究围绕分离式胶囊柔性止水技术、双峰GINA套箱止水技术展开。结果表明,分离式胶囊柔性止水技术可成功实现10~20m水深情形下的止水要求,并有效控制了失效风险。钢套箱自重力压缩GINA止水带可成功实现钢套箱与预制承台间的止水。 Prefabricated piers wet installation is a new construction technology, water-stop technology is the key control element, the flexible sealing of separate capsules is the original design of integrated capsule sealing technology optimization and improvement, the experimental study around the separation of flexible capsules Water stop technology, Bifeng GINA box water stop technology to start. The results show that the flexible capsule sealing technology can successfully seal the water in the depth of 10 ~ 20m and effectively control the failure risk. Steel Goss self-compressing GINA water stop can successfully stop the water between the steel glove box and the prefabricated cap.
