Ballast track subgrade structure with ballast blocking measure and construction method of ballast track subgrade structure
The invention relates to a ballast track roadbed structure with a ballast blocking measure and a construction method of the ballast track roadbed structure. A ballast track subgrade structure with ballast blocking measures comprises a railway ballast, a subgrade bed surface layer and a drainage system, ballast blocking strips are arranged on the upper portion of the subgrade bed surface layer and on the slope toes of railway ballast side slopes on the two sides of the railway ballast, the ballast blocking strips are embedded into the subgrade bed surface layer and arranged in the longitudinal direction of the subgrade bed surface layer, and road shoulder hardened layers are arranged on the outer sides of the ballast blocking strips. A plurality of drainage holes penetrating through the inner side and the outer side of the ballast blocking strip are formed in the ballast blocking strip in the longitudinal direction of the foundation bed surface layer at intervals and higher than the road shoulder hardened layer, and a plurality of first drainage channels are formed in the road shoulder hardened layer in the longitudinal direction of the foundation bed surface layer at intervals, transversely arranged along the foundation bed surface layer and communicated with drainage systems on the corresponding sides. The device integrates ballast blocking, road shoulder hardening and drainage, can play a certain role in protecting the loose surface layer of a ballast bed structure, can meet the requirement for road shoulder hardening, and can smoothly drain water in the ballast to a drainage system.
本发明涉及一种含挡砟措施的有砟轨道路基结构及其施工方法。一种含挡砟措施的有砟轨道路基结构，包括道砟、基床表层和排水系统，位于基床表层的上方且位于道砟两侧的道砟边坡的坡脚均设有挡砟条，挡砟条嵌入基床表层，挡砟条沿基床表层的纵向设置，挡砟条外侧设有路肩硬化层，挡砟条沿基床表层的纵向间隔设有若干贯通挡砟条内外侧的泄水孔，泄水孔高于路肩硬化层，路肩硬化层沿基床表层的纵向间隔设有若干第一排水通道，第一排水通道沿基床表层横向设置，第一排水通道连通对应侧的排水系统。其集挡砟、路肩硬化和排水一体，既能够对道床结构表层松动起到一定的保护作用，又能满足路肩的硬化，还可以顺畅将道砟内的水排至排水系统。
