Fabricated elastic ballastless track for passenger and freight collinear railway and construction method
The invention discloses an assembly type elastic ballastless track for a passenger and freight collinear railway and a construction method, belongs to the field of track construction, and aims to enhance the connection between an elastic supporting block and a roadbed slab and improve the integrity of a structure. Comprising a track panel and a roadbed slab arranged on an inverted arch backfilling layer. The track panel comprises a steel rail, a fastener and an elastic supporting block, and the elastic supporting block is assembled at the bottom of the steel rail through the fastener; a groove is formed in the roadbed slab, and the elastic supporting block is arranged in the groove; a filling cavity is formed between the groove wall of the groove and the outer surface of the elastic supporting block, and an elastic sleeve shoe is formed in the filling cavity in a cast-in-place mode. The elastic sleeve boots are cast in situ between the groove walls of the grooves of the elastic supporting blocks and the outer surfaces of the elastic supporting blocks, so that the phenomena of gaps and cavities can be effectively reduced, interlayer connection is enhanced, the structural integrity is improved, the risk of looseness of the elastic supporting blocks is reduced, and the service life of the assembly type elastic ballastless track is prolonged.
本发明客货共线铁路用装配式弹性无砟轨道及施工方法，属于轨道施工领域，目的是增强弹性支承块和道床板间的连接，提高结构的整体性。包括轨排和设置于仰拱回填层上的道床板；所述轨排包括钢轨、扣件和弹性支承块，所述弹性支承块经扣件组装于钢轨底部；所述道床板上设置有凹槽，所述弹性支承块设置于凹槽内；在凹槽的槽壁与弹性支承块外表面之间形成填充腔，填充腔内现浇形成弹性套靴。采用弹性支承块的凹槽的槽壁与弹性支承块外表面之间现浇弹性套靴，能有效减少空隙空洞现象，增强层间连接，提高了结构整体性，从而降低弹性支承块松动的风险，利于提高装配式弹性无砟轨道使用寿命。
