Embodiment Construction

[0027] The present invention will be described in detail below in combination with specific embodiments.

[0028] The invention relates to a beam-type adjustable ballastless track system, which comprises a beam-type track slab 1 and a rail support platform 4 arranged on the upper surface thereof. The beam-type track slab 1 is a prestressed structure, and two structures, solid slab and frame slab, can be used as required. In order to improve the strength and rigidity of the slab, the beam track slab 1 is a prestressed structure, and the beam track slab 1 can be made of concrete factory prefabrication, steel structure, resin material or other types of materials. At the four corners of the side of the beam track slab, there are bolt holes for lifting support, which can be used for transportation, fine adjustment and maintenance of the beam track slab. There are pre-embedded bolt sleeves in the rail support platform for installing fasteners and fixing rails.

Abstract

The invention relates to a beam type adjustable ballastless track system. The beam type adjustable ballastless track system comprises a beam type track plate and a rail bearing station arranged on theupper surface of the beam type track plate, an adjustable supporting seat is arranged between the lower part of the beam type track plate and a foundation, and the adjustable supporting seat comprises an adjustable supporting seat top plate, an adjustable supporting seat middle support and an adjustable supporting seat bottom plate from top to bottom. A heightening base plate is arranged betweenthe adjustable supporting seat top plate and the beam type track plate and is bolted through the adjustable supporting seat top plate, and bearing pad stone is arranged between the adjustable supporting seat bottom plate and the foundation and is bolted through adjustable supporting seat feet. According to the beam type adjustable ballastless track system, after a circuit foundation deforms, a fastening piece, the adjustable supporting seat and a grouting material leveling layer can be separately adopted for adjustment according to the magnitude of the foundation deformation amount, the adaptability of the ballastless track system for offline foundation deformation can be greatly improved, so that the ballastless track system is rapidly and conveniently repaired after spatial deformation occurs to the foundation engineering, and maintenance workloads are reduced.

Description

technical field [0001] The invention belongs to the field of track engineering, and in particular relates to a beam-type adjustable ballastless track system. Background technique [0002] The common ballastless track is poured on the concrete foundation or subgrade. When the foundation engineering suffers from settlement, arching and other diseases, it is generally repaired by demolition and reconstruction, bottom filling and adjustment layer, etc. The implementation is difficult, time-consuming, and costly. Operational disruption is high. [0003] The structure of the existing ballastless track system to limit the vertical and lateral displacement of the track slab is in the form of convex stops, grooves, and limit stops on both sides. After the foundation is deformed, the track geometry is adjusted by fasteners, and the adjustment ability is very small. Poor adaptability to foundation deformation.
