Prestressed concrete filled steel tube sleeper and preparation method thereof
The invention discloses a prestressed concrete-filled steel tube sleeper and a preparation method thereof, and belongs to the technical field of ballastless track concrete sleepers, the prestressed concrete-filled steel tube sleeper comprises two sleeper blocks arranged in the transverse direction, and a concrete-filled steel tube member is arranged between the two sleeper blocks; two ends of each concrete filled steel tube member are respectively and fixedly connected with the two sleeper blocks, each prestress connecting piece is fixedly connected with the two sleeper blocks, and at least one prestress connecting piece penetrates through two side wall surfaces of the sleeper along the transverse direction. The invention also discloses a corresponding preparation method. According to the prestressed concrete-filled steel tube sleeper and the preparation method thereof, the prestressed concrete-filled steel tube sleeper has high bending resistance, impact resistance and fatigue resistance, the end sleeper concrete structure can be effectively prevented from being broken or cracked in the train impact load bearing process, the stability of a ballast bed structure is guaranteed, the ballast bed maintenance cost is reduced, and the service life of the ballast bed is prolonged. And the safety and the stability of high-speed rail operation are further improved.
本发明公开了一种预应力钢管混凝土轨枕及其制备方法，属于无砟轨道混凝土轨枕技术领域，预应力钢管混凝土轨枕，包括沿横向设置的两块轨枕块，并在两块轨枕块之间布置有钢管混凝土构件，各钢管混凝土构件的两端分别与两块轨枕块固定连接，还包括具备预应力的预应力连接件，且各预应力连接均与两块轨枕块固定连接，至少一个预应力连接件沿横向贯穿轨枕的两侧壁面。还公开了对应的制备方法。本发明提供了一种预应力钢管混凝土轨枕及其制备方法，其具备较高的抗弯、抗冲击、抗疲劳性能，能够在承载列车冲击载荷过程中，有效避免端部轨枕混凝土结构出现破碎或裂纹，保障道床结构稳定性，降低道床维护成本，进而提高高铁运行的安全性和稳定性。
