Rain-shed-free large-gradient railway tunnel segmented intercepting drainage system
The invention relates to a rain-shed-free large-gradient railway tunnel segmented intercepting drainage system. Side ditches are formed in the two sides of the roadbed surface of a railway tunnel, andthe side ditches gather rainwater to a water collecting well at a tunnel portal; a water sealing layer is arranged from the top of the foundation bed surface layer of the railway tunnel to the outerwalls of the side ditches and is positioned below the roadbed surface; L-shaped water blocking grooves are formed in the foundation bed surface of the railway tunnel at an interval d being equal to ormore than 10 m and equal to or less than 20 m in the longitudinal direction of a line, the water blocking grooves are located between sleepers, the highest elevation of the water blocking grooves isflush with the bottoms of the sleepers, the water blocking grooves are filled with a water permeable material, the gradient of the bottoms of the water blocking grooves is consistent with that of thefoundation bed surface, and water is drained to the side ditches; transverse water retaining dams are arranged at entrances and exits of the railway tunnel and are located in holes between the two sleepers, and the two transverse ends of each water retaining dam are connected with the side ditches; and a combined detachable water retaining wall is arranged at the tops of the water retaining dams.Drainage is intercepted in a segmented mode, the water flow path is changed, and the advantages of being high in strength, high in crack resistance, good in waterproof performance and easy to construct are achieved.
本发明涉及一种无雨棚大坡度铁路地道分段拦截排水系统，铁路地道路基面两侧设置侧沟，所述侧沟汇集雨水至隧道口的集水井；铁路地道的基床表层顶部至侧沟外壁设置封水层，所述封水层位于路基面下方；铁路地道路基面沿线路纵向间隔10=<20m设置L型拦水槽，所述拦水槽位于轨枕之间，拦水槽最高标高和轨枕底平齐，所述拦水槽内填有透水材料，拦水槽底坡度同路基面一致并向两侧排水到所述侧沟；铁路地道隧道进出口均设置横向挡水埝，所述挡水埝位于两道轨枕之间的孔隙，所述挡水埝横向两端与侧沟相接；所述挡水埝顶部设置组合可拆卸式挡水墙。本发明分段拦截排水，改变水流路径，具有强度大、抗裂性能高、防水性能好以及施工简单的优点。
