摘要
当沿海软土地区的基坑开挖达到一定深度后,常规地下连续墙的设计和施工方法已不能满足工程需要,超深地下连续墙的施工难度也越来越大。结合天津滨海新区于家堡交通枢纽工程的地下连续墙工程,研究探讨超大型地下连续墙钢筋笼的吊装方法,通过多方案比较总结出行之有效的施工方案,在实际工程施工中取得良好效果。
In the coastal soft soil area, when the conventional design and construction method of concret foundation pit is excavated up to a certain depth, the e diaphragm wall can＇t satisfy the project requirement, and it is more difficult to construct the ultra-deep concrete diaphragm wall. Based on the construction of concrete diaphragm wall of Yujiabao Traffic Hub Project in Tianjin Binhai New area, the lifting cage of ultra-large concrete diaphragm wall are compared and researched. In addition, plan are summarized and applied well in some projects. options for the reinforcing the effective construction
