Adjustable ballastless track adapting to foundation deformation and adjusting method
The invention belongs to the technical field of railways, and discloses an adjustable ballastless track adapting to foundation deformation and an adjusting method.The adjustable ballastless track comprises a base on which a plurality of limiting bosses are poured; a plurality of prefabricated track plates, each prefabricated track plate is provided with a first rectangular limiting hole, the first rectangular limiting holes are inserted into the limiting bosses, and each prefabricated track plate is provided with a plurality of height adjusting holes; the height adjusting layer is connected between the base and the prefabricated track plate in a pressing manner; the horizontal adjusting layer is crimped between the first rectangular limiting hole and the limiting boss; the plurality of pre-embedded sleeves are pre-embedded in the corresponding height adjusting holes; and the plurality of height adjusting screw rods are in threaded connection with the corresponding embedded sleeves. By arranging the height adjusting layer and the horizontal adjusting layer, the height and transverse adjusting capacity of the ballastless track is improved, the problem that the deformation adjusting capacity of an existing ballastless track is insufficient when an offline foundation deforms greatly is solved, and the ballastless track deformation adjusting device can be applied to ballastless track construction in a complex geological section and disease treatment caused by operation line foundation deformation.
本发明属于铁路技术领域，公开了一种适应基础变形的可调整无砟轨道及调整方法，包括：底座，其上浇筑有多个限位凸台；多个预制轨道板，每个预制轨道板上有第一矩形限位孔，第一矩形限位孔插接在限位凸台上，每个预制轨道板上有多个高低调整孔；高低调整层，其压接在底座和预制轨道板之间；水平调整层，其压接在第一矩形限位孔和限位凸台之间；多个预埋套管，其预埋在对应的高低调整孔内；多个高低调整螺杆，其螺纹连接在对应的预埋套管上。通过设置高低调整层和水平调整层，提高了无砟轨道高低、横向调整能力，解决了线下基础大变形时现有无砟轨道变形调整能力不足的难题，可应用于复杂地质区段无砟轨道建造，运营线路基础变形引起的病害处置。
