The invention relates to the technical field of tunnel waterproofing and drainage, and more particularly, to a visual and maintainable road tunnel silting prevention and drainage system. It is used to solve the problem that the existing tunnel drainage system is easy to block and seepage during the drainage process, and it is difficult to find the blockage point. This visible and maintainable highway tunnel anti-silting drainage system includes road drainage system, side ditch well point dewatering system and side wall visual drainage system; Blind pipe, vertical drainage blind ditch, visible well and visible cover; side ditch well point dewatering system includes side ditch and dewatering well, and the dewatering well is built in the side ditch; side wall visual drainage system includes side wall blind ditch, Side wall drain pipe, combined permeable pipe and visual water receiving box, side wall blind ditch is set inside the tunnel side wall. Through this solution, the technical effect of easy drainage and fast finding of siltation points, targeted maintenance and dredging, and reduction of water leakage in the tunnel can be achieved.
Description
technical field [0001] The invention relates to the technical field of tunnel waterproofing and drainage, and more particularly, to a visual and maintainable road tunnel silting prevention and drainage system. Background technique [0002] Due to the complex geological conditions of surrounding rocks of expressway tunnels passing through mountainous areas, common diseases such as lining leakage water and road surface water will appear after the tunnel has been in operation for many years, which will have a certain impact on the safety of tunnel operation. In severe cases, the tunnel drainage system will be blocked, a large amount of accumulated water behind the lining cannot be discharged, and the water pressure behind the lining will increase, threatening the safety and stability of the lining structure. [0003] A large number of engineering investigations and experimental studies have shown that there are two main reasons for the blockage of the tunnel drainage system: on...
