Concrete-filled steel tube sleeper type ballastless track with vibration reduction function and construction method
The invention discloses a concrete filled steel tube sleeper type ballastless track with a vibration reduction function 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, a plurality of roadbed slabs and a plurality of steel bottom plates. And a plurality of concrete filled steel tube sleepers are inserted into the roadbed slabs in parallel at intervals. A plurality of upper steel pipes and a plurality of steel springs are inserted into each roadbed slab, the upper steel pipes are arranged in two rows, the steel springs are inserted into the corresponding upper steel pipes, and the upper steel pipes and the steel springs protrude out of the roadbed slabs. A plurality of lower steel pipes are fixedly arranged on the top face of each steel bottom plate, the bottom ends of the upper steel pipes are coaxially inserted into the corresponding lower steel pipes in a sliding mode, and the bottom ends of the steel springs are inserted into the corresponding lower steel pipes. According to the concrete-filled steel tube sleeper type ballastless track with the vibration reduction function, the geometric shape and position keeping capacity of the sleeper can be improved, and the buffering and vibration reduction effects on the sleeper can be effectively achieved.
本发明公开了一种具有减振功能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。所述无砟轨道包括两个钢轨、多个扣件、多个钢管混凝土轨枕、多个道床板和多个钢底板。多个钢管混凝土轨枕平行间隔插装在各道床板中。各道床板插装多个上钢管和多个钢弹簧，多个上钢管呈两列布置，各钢弹簧插装在相对应的上钢管中，且上钢管和钢弹簧均凸出道床板布置。各钢底板的顶面固定布置有多个下钢管，各上钢管的底端可滑动地同轴插装在相对应的下钢管中，且各钢弹簧的底端插装在相对应的下钢管中。本发明实施例提供的一种具有减振功能的钢管混凝土枕式无砟轨道，不仅可以提高轨枕几何形位保持能力，还能有效对轨枕起到缓冲减振的作用。
