Method for adjusting elevation of ballastless track
The invention provides a method for adjusting the elevation of a ballastless track. The ballastless track structure at least comprises a track, a sleeper, a track plate and a supporting layer which are arranged from top to bottom. The method is characterized by comprising the following steps that: a track falling amount is determined; a cutting layer is cut from the supporting layer and removed, so that a cutting seam can be formed in the supporting layer, the thickness of the cutting layer is designed to be larger than the falling track amount, and the upper surface and the lower surface of the cutting layer are designed to be parallel to the surface, facing the supporting layer, of a track plate; an elevation control cushion block is provided in the cutting seam, the thickness of the elevation control cushion block is the difference value between the thickness of the cutting layer and the track falling amount; the ballastless track structure above the cutting seam is enabled to slowly fall on the elevation control cushion block; and grouting is conducted in the cutting seams. According to the method, the elevation of the track is adjusted with low cost and high efficiency, and influence on driving is small.
本发明提供了一种调整无砟轨道高程的方法，所述无砟轨道结构至少包括由上至下布置的轨道、轨枕、轨道板以及支承层，其特征是，所述方法包括以下步骤：确定落道量；从所述支承层上切取切割层并将其移除以在所述支承层上形成切割缝，其中所述切割层的厚度被设计为大于落道量，所述切割层的上表面和下表面被设计为平行于所述轨道板朝向所述支承层的表面；在所述切割缝内提供高程控制垫块，所述高程控制垫块的厚度为所述切割层的厚度与落道量的差值；使位于所述切割缝上方的无砟轨道结构缓慢落在所述高程控制垫块之上；向所述切割缝中灌浆。该方法实现了实现低成本、高功效且对行车影响小地调节轨道高程。
