摘要
顶管始发井接收井深基坑开挖和泥水顶管掘进过江施工是上海复兴东路越江电力管道施工的关键技术,特别是深基坑开挖施工,涉及到坑底土体和边坡的稳定,以及施工期间的流砂和管涌问题。讨论了基于始发井接收井周边工程地质环境保护的降水加固施工技术和顶管掘进过程中的自动测量控制技术,通过工程实践和施工同步监测数据表明,该施工技术是有效的。
The excavation of a deep foundation pit for the starting or receiving well and the slurry pipe jacking tunnelling underground Huangpu River are the key technology of the construction on Fuxing East Road Electric Power Tunnel Project of Shanghai.The former,specially,involves the stability of soil body at the bottom and the slope of the deep fundation pit,as well as the shifting sand and piping during its construction.It is dicussed the reinforcement technology by lowering water level based on the environmental protection of engineering geology and construction site around the starting or receiving well,and the auto surveying control technology of pipe jacking tunnelling.It proves effective by construction practicing and synchronism monitoring to the ground and the building.
