Tramcar track paving structure in transition area of level crossing and construction method of tramcar track paving structure

Abstract

The invention relates to the technical field of road pavement, in particular to an electric vehicle track pavement structure in a level crossing transition area and a construction method of the electric vehicle track pavement structure. A polyurethane high elastomer and an ultra-high performance concrete block are filled between a pavement layer and a steel rail, and the ultra-high performance concrete block is arranged above a roadbed layer; the polyurethane high elastomer is arranged above the ultra-high performance concrete block, and the polyurethane high elastomer and the ultra-high performance concrete block are combined to form a buffer energy absorption transition section of the pavement layer. The invention has the advantages that the problems of cracking, delaminating, slippage, rutting, poor durability and the like can be effectively solved; the structure has high flexibility and self-adaptability, is high in the durability, realizes smooth connection and high-efficiency waterproof performance, can be repaired together with a connected pavement, is free of maintenance and long in the service life, and can rapidly be delivered for traffic, and is simple in maintenance.

Description

technical field [0001] The invention relates to the technical field of road pavement, in particular to a tram track pavement structure and a construction method in a level crossing transition zone. Background technique [0002] Tram has become the best choice for many urban rail transit methods because of its obvious advantages such as low construction cost, low construction difficulty, high safety factor, high environmental protection factor and common use of lanes. However, the laying of tram tracks in the transition zone of existing level crossings is generally that the steel rails are in direct contact with the asphalt pavement, which will cause the following problems: the differential settlement of the steel rails and the road leads to permanent deformation at the joints; Dynamic deformation occurs; there is a difference in settlement at the joint between the rail and the road, resulting in the impact load of social vehicles passing through the intersection, which furth...

Problems solved by technology

However, the laying of tram tracks in the transition zone of existing level crossings is generally that the steel rails are in direct contact with the asphalt pavement, which will cause the following problems: the differential settlement of the steel rails and the road leads to permanent deformation at the joints; Dynamic deformation occurs; there is a difference in settlement at the joint between the rail and the road, resulting in the impact load of social vehicles passing through the intersection, further aggravating the disease, etc.

This will lead to cracking, delamination, slippage, rutting, etc., which will greatly affect the appearance, making the quality of the road surface at the tramway look very poor, and seriously affecting the image of the city
