Three-dimensional reinforcing device and reinforcing method for ballastless track sleeper of high-speed railway
The invention discloses a high-speed railway ballastless track sleeper three-dimensional reinforcing device and method, the device comprises a claw type steel frame, self-locking bolts and embedded steel bar anchoring, self-leveling quick-hardening mortar is poured on the surface of a roadbed slab for leveling, the claw type steel frame is fixed in an embedded steel bar anchoring mode, then the longitudinal self-locking bolt, the transverse self-locking bolt and the vertical self-locking bolt are sequentially and synchronously tightened, and the embedded steel bar anchoring mode is adopted. The self-locking bolt is tightly attached to the sleeper surface, three-dimensional reinforcement of the sleeper and safety and stability of a track structure are achieved, and the self-locking bolt has the advantages of being easy to disassemble and capable of being repeatedly used. The device solves the practical problems that an existing reinforcing device cannot achieve transverse, longitudinal and vertical three-dimensional reinforcing and is not suitable for the reinforcing requirement of a long-strip-shaped sleeper structure and the like, and is suitable for structural reinforcing during replacement or emergency repair of ballastless track sleepers and switch sleepers of high-speed railways.
本发明公开了一种高速铁路无砟轨道轨枕三维加固装置及加固方法，该装置包括爪式钢架、自锁螺栓和植筋锚固，通过在道床板表面浇筑自流平快硬砂浆找平，采用植筋锚固形式固定爪式钢架，然后依次同步拧紧纵向、横向、竖向自锁螺栓，使自锁螺栓与轨枕面紧密贴合，实现轨枕的三维加固和轨道结构的安全稳定，具有易于拆卸，可重复使用的特点。本发明解决了现有加固装置无法实现横、纵、竖向三维加固，不适用于长条状轨枕结构的加固需求等现实问题，适用于高速铁路无砟轨道轨枕、岔枕更换或应急抢修期间的结构加固。
