摘要
以上海虹桥枢纽水系新角浦河道深基坑施工为例,针对在软土基础和周边特定条件下,深基坑施工过程中的围护钢板桩施工、深井井点降水、基坑土方开挖、型钢腰梁和对称钢管支撑系统的形成和后期拆除等工序工法,及过程控制和技术要求进行了简要阐述,并对施工过程中突发的状况和应急处理措施进行了总结。
For the deep foundation excavation on the Xinjiaopu river in Shanghai Hongqiao river system as an example,under soft soil foundation and special surrounding environment,this paper briefly introduces some key construction points of the deep foundation excavation which mainly include construction of steel sheet pile,deep well dewatering,soil excavation and production and removing of profile steel as waist beam and symmetrical steel pipe support system.At the same time,this paper also summarizes requirement for construction process control and technical requirements,and moreover summarizes emergency situation and treatment measures during construction.
