在常规设计理念中,顶管工程均由始发井-接收井对应构成。而在上海虹桥能源中心项目中,由于特大直径钢顶管须衔接南站和北站(一项两站)两个单体,且须穿越新角浦河,施工难度极大。EPC承包商团队在综合分析南站、北站地下室建筑结构、深基坑围护墙形式以及所在地理位置周边环境、地形地貌的基础上,决定利用南站地下室结构取代钢顶管施工接收井。省略了接收井设计及其结构施工。从设计源头改变了传统套路,使之更科学、更合理,并以结构变形缝软型-硬型-柔性接口等技术创新,解决了既有建筑防渗漏问题,不仅缩短了项目施工周期,还节省了巨额建筑投资。
In conventional design concepts, the jacking works consist of the originating well-receiving well. However, in the Shanghai Hongqiao Energy Center project, it is extremely difficult to construct due to the oversized diameter steel pipe jacking that connects two units of South Station and North Station (one station and two stations) and crossing the new Kok Pu River. EPC contractor team decided to replace the steel receiving pipe construction with the basement structure of South Station on the basis of comprehensive analysis of the building structure of basement of South Station and North Station, the form of retaining wall of deep foundation pit and the surrounding environment and topography of the location. The design of receiving well and its construction are omitted. From the design of the source to change the traditional routines to make it more scientific and more reasonable, and the structural deformation of soft-type - hard-flexible interface technology innovation to solve the existing building leakage prevention, not only shorten the project construction cycle, Also saved a huge investment in construction.
