Ballastless track roadbed slab rebuilding construction transition structure and construction method
The invention relates to the technical field of railway construction, in particular to a ballastless track roadbed slab rebuilding construction transition structure and a construction method, a plurality of wooden sleepers are arranged in parallel at equal intervals in the extending direction of a track, and the lower portions of the two ends of each wooden sleeper are connected with sleeper blocks; the filling bag is arranged between the sleeper block and the roadbed slab rebuilding base plane, and the filling bag is filled with filler, so that the load borne by the sleeper block downwards acts on the roadbed slab rebuilding base plane through the filling bag. The overall transition structure is composed of the wooden sleepers, the sleeper blocks and the filling bags, transition operation and use of a business line can be met through simple installation and connection, a fixed pouring structure is not formed on the roadbed slab rebuilding base face, and when roadbed slab rebuilding is conducted in the later period, only simple disassembly is needed, and the construction cost is reduced. And the rebuilding construction time of the ballast track roadbed slab of the business line is saved.
本发明涉及铁路施工技术领域，尤其涉及一种无砟轨道道床板重筑施工过渡结构及施工方法，多个木枕沿着轨道延伸方向等间距平行排列，每个木枕的两端下部均连接枕木块；填充袋设置于枕木块与道床板重筑基面之间，填充袋内充填有填充物，以使枕木块受到的载荷通过填充袋向下作用于道床板重筑基面。整体过渡结构由木枕、枕木块和填充袋组成，通过简单地安装连接即可满足营业线过渡运营使用，而且，没有在道床板重筑基面上形成固定的浇筑结构，后期进行道床板重筑时，只需要进行简单拆除即可，节约了营业线砟轨道道床板重筑施工时间。
