不良地质条件下顶管始发井逆作法施工技术研究OA
Study on Top-down Construction Technology of Pipe Jacking Starting Well under Bad Geological Conditions
以内蒙古引绰济辽工程为例,阐述了该工程顶管始发井在不良地质条件下采用的逆作法施工工艺,辅以超前灌浆、井点降水、监控量测以及信息反馈等施工手段成功解决不良地质条件下始发井逆作法开挖支护及混凝土施工带来的一系列质量与安全问题,有效地避免了采用传统竖井基坑施工存在的各种风险,总结出不良地质条件下逆作法施工工艺和关键工序以及控制要点,所取得的经验可为今后类似工程参考.
Taking the Diversion Project from the Zhuoer River to the Xiliao River in Inner Mongolia as an exam-ple,this paper expounds the top-down construction technology of the pipe jacking starting well under bad geo-logical conditions,by means of advanced grouting,well point dewatering,monitoring,measuring,and informa-tion feedback,a series of quality and safety problems under bad geological conditions have been solved by exca-vation and support and concrete constr…查看全部>>
