Railway road and bridge transition section abutment back assembly type buffer structure and construction method thereof
The invention discloses a railway road and bridge transition section abutment back assembly type buffer structure and a construction method thereof.The buffer structure comprises a roadbed longitudinal frost heaving deformation coordination plate which can elastically deform and retract under longitudinal extrusion, and the roadbed longitudinal frost heaving deformation coordination plate is of a partitioned assembly type structure; the roadbed longitudinal frost heaving deformation coordinating plate is tightly attached to the back of the bridge abutment; the drainage structure is used for collecting and draining water infiltrated from the roadbed and the top surface of the bridge abutment, and the drainage structure is arranged on the longitudinal frost heaving deformation coordination plate of the roadbed. According to the method, the adverse effects of longitudinal frost heaving deformation and frost heaving force of the abutment back roadbed filler on the bridge abutment and the bridge structure can be remarkably reduced, and the problem that the transition section damage of abutment deformation caused by three-way frost heaving of the road and bridge transition section roadbed in the cold region is rarely considered at home and abroad is solved; the method is of great significance in improving the service performance of the abutment back of the railway road and bridge transition section in the cold region.
本发明公开了一种铁路路桥过渡段台背装配式缓冲结构及其施工方法，其缓冲结构包括受纵向挤压可弹性变形以及回缩的路基纵向冻胀变形协调板，所述路基纵向冻胀变形协调板为分块组装式结构，路基纵向冻胀变形协调板紧贴桥台台背设置；还包括用于将路基内及桥台台顶面渗下水分汇集排出的排水结构，排水结构设在路基纵向冻胀变形协调板上。本发明可显著减少台背路基填料的纵向冻胀变形和冻胀力对桥台和桥梁结构的不利影响，弥补了国内外鲜有考虑寒区路桥过渡段路基三向冻胀引起墩台变形的过渡段病害问题，这对于提高寒区铁路路桥过渡段台背的服役性能具有十分重要的意义。
