Deviation correction method for CRTS III type slab ballastless track structure
The invention relates to the technical field of track deviation rectification, in particular to a deviation rectification method for a CRTS III type slab ballastless track structure, which comprises the following steps of: determining the horizontal transverse deviation rectification quantity and the horizontal vertical deviation rectification quantity of the track structure; the steel rail is pushed aside, and the track plate and the self-compacting concrete layer adhering to the lower portion of the track plate are jacked and moved away; three-dimensional size parameters of the self-compacting concrete layer limiting block and the limiting groove in the base are obtained; trimming a self-compacting concrete layer limiting block and/or a limiting groove in the base according to the horizontal transverse deviation correction amount, the horizontal vertical deviation correction amount and the three-dimensional size parameters of the self-compacting concrete layer limiting block and the limiting groove in the base; isolating layers are arranged on the surface of the base and the limiting groove; and the track plate and the self-compacting concrete layer are moved back, the steel rails are recovered, fasteners are finely adjusted, open joint grouting is conducted, and a line is opened. According to the method, the distance of the deviation rectifying section is not limited, the single track plate can be independently constructed, the construction efficiency is high, and the structural performance of the track is not affected.
本发明涉及轨道纠偏技术领域，具体涉及一种CRTSⅢ型板式无砟轨道结构的纠偏方法，包括如下步骤：确定轨道结构的水平横向纠偏量、水平竖向纠偏量；拨开钢轨，顶升并移开轨道板及粘附于所述轨道板下方的自密实混凝土层；获取自密实混凝土层限位块以及底座上的限位凹槽的三维尺寸参数；根据所述水平横向纠偏量、水平竖向纠偏量、自密实混凝土层限位块以及底座上的限位凹槽的三维尺寸参数，修整自密实混凝土层限位块和/或底座上的限位凹槽；在底座表面及限位凹槽上设置隔离层；移回轨道板和自密实混凝土层，恢复钢轨并精调扣件，离缝注浆，开通线路。本发明对纠偏区段距离没有限制，单块轨道板可独立施工，施工效率高，且不影响轨道结构性能。
