Study On The Freeway Tunnel's Drainage Technologies And Processes

China in building the road tunnel technology has made considerable progress and raise,but a good road tunnel in the existence of varying degrees in which, through infiltration water on safe driving in effect,but also threaten the stability of the tunnel structure and lowers the efficiency of operations.Therefore, in order to improve the present very good road tunnel;the water seepage through with the road tunnel for drainage development and research and analysis on the basis of the summary of the tunnel for the technology of the main problem。And the practice and test and made to the concrete surface down the construction process,to protect the integrity of waterproof layer;also made of plastic component waterproof layer water and construction processes to improve the road tunnel waterproof layer construction。In the gaps between the "three" the drainage and be buried in the back to the end of the rubber,and dwelled on its working mechanism and construction processes;the seam of the "three protection" the technology to further improvement。The two new technique and technology studies,greatly improving the road tunnel in a drain on the rationalization of the process of construction。in the future of the tunnel,using the role playedfor the design and construction...
