Study on Top-down Construction Technology of Pipe Jacking Starting Well under Bad Geological Conditions
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 construction of top-down starting well,it effectively avoids all kinds of risks in the construction of traditional shaft foundation pit,sums up the construction technology and key procedures of top-down construction method under bad geological conditions and control points,and the experience obtained can provide reference for similar projects in the future.
