Application of Pipe Jacking Construction Technology in Urban Water Supply and Transportation Supporting Renovation
In response to the problems of low water supply guarantee rate and lack of guarantee for water safety in Ruyuan Yao Autonomous County,a water supply network for Nanshui Reservoir will be constructed to solve the water use problem for residents.In recent years,long-distance pipe jacking technology has been widely used in the construction of pipeline networks.Taking the top pipe construction section of the expressway section in Nanshui Reservoir water supply project as an example,this paper provides a detailed introduction to the layout of the top pipe construction plan,construction principle,selection of the top pipe machine,top force calculation,and equipment installation in the top pipe construction process of the engineering construction top pipe construction technology,and proposes contingency plans to deal with settlement.
