Reinforcing structure for alleviating tramcar trackside asphalt pavement cracking

Abstract

The invention relates to the technical field of tramcar track construction and in particular to a reinforcing structure for alleviating tramcar trackside asphalt pavement cracking. The reinforcing structure comprises sleepers, wherein the sleeper is arranged in equal distances on a ballast covering; the sleepers are buried into the ballast covering; steel rails are arranged on the sleepers; bucklecovers are arranged on buckles; protection plates are arranged on the buckles; flexible wrapping materials are arranged on both the sleepers and parts beside the steel rails between adjacent sleepers; transverse baffle plates are fixed on the outer sides of the flexible wrapping materials through anchoring bolts; pre-embedded bolt sleeves are arranged on the anchoring bolts in positions corresponding to a concrete adjusting layer; the concrete adjusting layer and an asphalt paving layer are sequentially arranged above the ballast covering. As steel plates are additionally arranged above the buckle covers, so that isolation and protection of buckle covers can be enhanced, the buckle covers are small in load and slight in deformation, asphalt of trackside can be effectively transversely protected by the steel plates on the outer sides of the flexible wrapping materials, the construction compactness of asphalt paving can be improved, and the cracking influence of transverse impact of trains to trackside asphalt can be alleviated.

Description

technical field [0001] The invention relates to the technical field of tramway track construction, in particular to a reinforcing structure for improving cracking of asphalt pavement beside the tramway. Background technique [0002] At the crossing of municipal roads, the trams usually use flexible wrapping materials made of rubber on both sides of the rails and set nylon fastener covers on the fasteners to protect the rail components and isolate the rails from the municipal asphalt pavement structure. , to buffer the impact of rail vibration on asphalt pavement, and to protect the normal working performance of fasteners. [0003] There are following defects in this technology: [0004] (1) Since the fastener cover needs to be installed above the rail fastener, the fastener cover is a cavity structure made of nylon material, which leads to the continuous rolling of this part when the road vehicle passes the rail in the later stage, and the fastener cover is deformed, result...

AI Technical Summary

Problems solved by technology

[0004] (1) Since the fastener cover needs to be installed above the rail fastener, the fastener cover is a cavity structure made of nylon material, which leads to the continuous rolling of this part when the road vehicle passes the rail in the later stage, and the fastener cover is deformed, resulting in The deformation of the asphalt surface is uncoordinated, subject to complex stresses such as tension and shear, and the top of the fastener cover is prone to cracking

[0005] (2) The trackside is equipped with flexible wrapping material, which has a certain degree of elasticity. When the asphalt pavement is constructed and rolled by the railside, the wrapping material will be deformed by lateral extrusion, making it difficult to meet the compaction degree of the asphalt pavement. Due to the design requirements, this part will be continuously impacted and rolled when the road vehicles pass the rails in the later stage, and the asphalt beside the track will easily peel off and loosen the asphalt concrete due to insufficient compaction.
