摘要
工程建设中经常遇到地下室结构外墙紧贴基坑围护桩(地下连续墙)的情况,因而只能使用单侧支模的方法进行墙体施工,从而加大了施工难度。在南京市圣和酒店及六朝博物馆项目地下室结构施工中,采用钢管扣件排架斜撑体系进行单侧支模施工,获得了良好的效果。通过对该方法在构造设计、受力体系、优缺点和施工质量安全控制要点方面的总结,以期为同类工程施工提供借鉴。
It is common that the basement exterior wall is close to the foundation pit supporting pile during the construction. As a result, the only solution to the wall construction is to use the unilateral formwork method, however it increases the construction difficulty. Such unilateral formwork with steel pipe fastener and diagonal support system has been applied to the construction of basement structure for the Shenghe Hotel and the Oriental Metropolitan Museum in Nanjing, which has achieved good effect. This paper summarizes the structure design, applied force system, merits and demerits, as well as key control essentials of construction quality, so as to provide references for similar projects.
