地下连续墙内侧结构空腔单侧支模施工工艺

Construction Technology of Single Side Formwork of Inner Structure Cavity of Diaphragm Wall

结合南京华新城AB地块项目地下室外墙施工实践,介绍了一种新型空腔支模的构造设计、施工工艺及质量控制要点。通过采用空腔单侧支模、单元式嵌入模板,解决了空间不足情况下的模板支设难题。经过现场试验及大面积施工的验证,新支模方法具有良好的工效,可为同类工程施工提供借鉴。

Combined with the construction practice of basement exterior wall of Nanjing Huaxin City AB plot project,the paper introduces the structural design,construction technology and quality control points of a new type of cavity formwork.By adopting cavity single side formwork and embedded formwork unit,the difficult problem of formwork erection under the condition of insufficient space is solved.After field test and large-scale construction verification,the new formwork support method has good work efficiency,which can provide reference for similar engineering construction.
