地连墙钢筋笼吊装技术控制要点

Key Points of Control on Hoisting Technology of Steel Cage of Ground Wall

本工程为天津地铁8号线一期工程起点站,特点是地连墙钢筋笼质量大,异型钢筋笼数量较多,对吊装要求更加严格。钢筋笼吊装作业是地连墙施工的关键环节,也是施工过程中危险性较大的环节之一。根据地连墙施工的实际情况,简要分析地连墙钢筋笼吊装技术,为安全施工提供参考。

This project is the starting point of the first phase of Tianjin Metro Line 8. It is characterized by the large weight of ground wall reinforcement cages, the large number of special-shaped reinforcement cages, and more stringent requirements for lifting. The lifting and installation of reinforcement cage is the key link in the construction of Diaphragm Wall, and it is also one of the most dangerous links in the construction. According to the actual situation of underground diaphragm wall construction, this paper briefly analyzes the lifting technology of reinforcement cage of underground diaphragm wall, and provides certain technical guidance for safe construction.
