Grid structure for renovating ballast sinking of existing operating railway and construction method
The invention provides a grating structure for renovating railway ballast sinking of an existing operating railway. A foundation bed grating is laid between a railway ballast bottom layer and a subgrade foundation bed surface layer; the foundation bed grids are connected through connecting rods, and hot clay cloth is laid below the foundation bed grids and connected with the foundation bed grids; the road shoulder grids are arranged on the two sides, perpendicular to the line direction, of the foundation bed grid, and the road shoulder grids and the foundation bed grid are connected through connecting rods. The side slope grids are arranged on the two sides, perpendicular to the line direction, of the road shoulder grid, and the side slope grids and the road shoulder grid are connected through connecting rods. According to the method, the problems caused by railway ballast sinking of the existing operating railway are solved, the bearing capacity of a foundation bed is improved, the service life of the ballast bed is prolonged, the quality and stability of railway ballast particles are effectively ensured, and the potential safety hazard of railway driving is eliminated.
本发明提供了一种用于整治既有运营铁路道砟下沉的格栅结构，基床格栅铺设于道砟底层及路基基床表层之间；基床格栅与基床格栅之间通过连接杆连接，基床格栅下铺设有热粘土工布，热粘土工布与基床格栅相接；路肩格栅设置于基床格栅垂直于线路方向两侧，路肩格栅与基床格栅之间通过连接杆连接；边坡格栅设置于路肩格栅垂直于线路方向两侧，边坡格栅与路肩格栅之间通过连接杆连接。本发明解决了既有运营铁路由道砟下沉产生的病害，提高了基床承载力，延长了道床使用周期，有效的确保了道砟颗粒的质量和稳定，消除了铁路行车安全隐患。
