Research on Construction Technology of Full-section Rock breaking Pipe Jacking for Water Conservancy Engineering Undercrossing Expressway
With the rapid development of expressway construction in China,water conservancy engineering often needs to pass under the expressway.Pipe jacking construction technology is widely used in such engineering because of its advantages of simple construction and little impact on the environment.Taking a flood control and water diversion project as an example,this paper analyzes the construction technology of full-section rock breaking pipe jacking,including construction preparation,hole entrance sealing,working well construction,pipe joint interface treatment,etc.,aiming to explore a scientific and reasonable pipe jacking construction scheme and provide reference for the construction of water conservancy engineering projects.
