Concrete-filled steel tube sleeper type ballastless track and construction method thereof
The invention discloses a concrete-filled steel tube sleeper type ballastless track, and the ballastless track comprises a base, a roadbed slab and a concrete-filled steel tube double-block sleeper, and is characterized in that a plurality of upward concave grooves are formed in the lower part of the roadbed slab, the base is provided with a plurality of upward convex bosses formed during self-pouring, and a vibration reduction layer surrounding the bosses is arranged between the base and the roadbed slab. Movement of the roadbed slab is limited by the roadbed slab groove and the base boss, the contact area of the roadbed slab and the base is increased, and the integrity of the track structure is improved. Meanwhile, the thickness of the base is reduced, and the height of the rail structure is reduced. A rubber anti-vibration pad is additionally arranged between the roadbed slab and the base, so the anti-vibration performance of the track structure is guaranteed, and the novel ballastless track structure can be applied to the field of urban rail transit with high environmental requirements. An elastic base plate is arranged between the roadbed slab groove and the base boss, so thevibration reduction performance can be enhanced, a buffering effect can be achieved, and adverse effects of stress concentration on a track structure are reduced.
本发明公开了一种钢管混凝土枕式无砟轨道，包括底座、道床板、钢管混凝土双块式轨枕，其特征在于：道床板下部设有若干向上内陷的凹槽，底座具有自身浇筑时形成的若干向上凸起的凸台，底座与道床板之间设有围绕凸台的减振层。道床板凹槽、底座凸台限制了道床板的移动，增加了道床板与底座的接触面积，提高了轨道结构的整体性。同时，底座厚度也有所减小，降低了轨道结构的高度。在道床板和底座之间增加橡胶减振垫，保证了轨道结构的减振性能，使得新型无砟轨道结构可应用于对环境要求较高的城市轨道交通领域。道床板凹槽和底座凸台之间设置弹性垫板不仅能增强减振性能，也可以起到缓冲作用，减小了应力集中对轨道结构产生的不利影响。
