Adjustable concrete filled steel tube sleeper type ballastless track and construction method
The invention discloses an adjustable concrete filled steel tube sleeper type ballastless track and a construction method, and belongs to the technical field of ballastless tracks. The ballastless track comprises two steel rails, a plurality of fasteners, a plurality of concrete filled steel tube sleepers and a track bed. And the steel rails are mounted on the fasteners. The concrete filled steel tube sleepers are arranged in parallel at intervals, each concrete filled steel tube sleeper comprises an adjusting pipe and a sleeper unit, each sleeper unit comprises a steel pipe and a sleeper block, one end of each steel pipe is inserted into the corresponding sleeper block, the steel pipes are filled with concrete filler, and the sleeper blocks and the corresponding concrete filler are integrally formed through concrete in a pouring mode. The two steel pipes are movably and coaxially inserted into the two ends of the adjusting pipe respectively, and the ballast bed is of a plate-shaped structure formed by cast-in-place concrete among the multiple steel pipe concrete sleepers. According to the adjustable concrete-filled steel tube sleeper type ballastless track provided by the embodiment of the invention, not only can the preparation of the sleeper units be completed in advance through pouring, but also the gauge of the two steel rails can be adjusted.
本发明公开了一种可调的钢管混凝土枕式无砟轨道及施工方法，属于无砟轨道技术领域。无砟轨道包括两个钢轨、多个扣件、多个钢管混凝土轨枕和道床。各钢轨安装在扣件上。多个钢管混凝土轨枕平行间隔布置，各钢管混凝土轨枕均包括调节管和轨枕单元，各轨枕单元均包括钢管和轨枕块，钢管的一端插装在轨枕块中，且钢管内充设有混凝土填充料，各轨枕块和相对应的混凝土填充料通过混凝土一体浇筑成型，两个钢管分别可活动地同轴插装在调节管的两端，道床为在多个钢管混凝土轨枕之间现浇混凝土成型的板状结构。本发明实施例提供的一种可调的钢管混凝土枕式无砟轨道，不仅可以提前通过浇筑完成轨枕单元的制备，还能调节两个钢轨的轨距。
