Ballastless rail turnout open joint renovation structure and method
The invention discloses a ballastless rail turnout open joint renovation structure and method. The ballastless rail turnout open joint renovation structure comprises a base plate, a turnou trail plateand a sleeper, and an open joint exists between the base plate and the turnout rail plate. The structure is characterized in that the structure further comprises a plurality of PVC pipes penetratingthrough the open joint, grouting pipes inserted into the two ends of the PVC pipes, a plurality of exhaust holes which are perpendicular to the PVC pipes and distributed at equal intervals, soft air pipes inserted into the top ends of the exhaust holes and colloid filled in the open joint, and the two ends of the PVC pipes and the ends, away from the PVC pipes, of the exhaust holes are sealed through edge sealing glue; A plurality of vertically crossed through holes are formed in the PVC pipes, the defects in the prior art are overcome, the interior of the open joint can be blocked, construction can be conducted within an effective skylight time point, train operation of an existing line does not need to be interrupted, the influence on the existing line is small, and speed limiting does not need to be adopted.
本发明公开了一种无砟轨道道岔离缝整治结构及方法。该一种无砟轨道道岔离缝整治结构，包括底座板、道岔轨道板和轨枕，所述底座板与道岔轨道板之间存在离缝，其特征在于：还包括多个贯穿离缝的PVC管、插接在PVC管两端的注浆管、垂直于PVC管的多个等距分布排气孔、插接在排气孔顶端的软气管和填充于离缝内的胶体，所述PVC管的两端和排气孔远离PVC管的一端均采用封边胶封堵，所述PVC管上开设有多个垂直十字交叉的通孔，克服了现有技术的不足，能够实现对离缝内部进行封堵，能在有效的天窗时间点内进行施工，无需中断既有线的列车运营，对既有线的影响较小，不用采取限速。
