Rail traffic level crossing pavement laying strengthening structure and laying method

Abstract

The invention discloses a rail traffic level crossing pavement laying strengthening structure and a laying method, wherein by mounting prefabricated limiting blocks on the two sides of a steel rail respectively, fasteners are housed in accommodating grooves on concrete prefabricated blocks of the limiting blocks respectively; the limiting blocks are relatively fixed with the steel rail through filled concrete in the accommodating grooves respectively, so that the fasteners can be effectively avoided from being directly contacted to a pavement concrete layer of a municipal pavement, and the problem that steel rail components are extruded and vibrated for a long time to cause cracking of the pavement is solved; and meanwhile, due to the existence of a steel plate structure, the problem that the pavement structure at steel rail fastener parts are weaker is effectively solved. The pavement laying strengthening structure is particularly suitable for a level crossing for both tramcars and social vehicles to crossly pass, effectively ensures the beautiful degree and the service life of the municipal pavement, also guarantees stable running of the tramcars at the same time and is convenient to overhaul and change the steel rail and the fasteners.

Description

technical field [0001] The invention relates to a pavement reinforcement structure and a pavement method of a rail transit level crossing. Background technique [0002] Rail transit level crossings on urban roads, such as trams, mainly use buried track structures because of their driving track structure. Although there are many pavement structures currently used, the extension direction along the length of the track is usually Multiple fasteners are used to fix the track and the track bed, and the fasteners are directly buried in the road and directly contact with concrete or asphalt concrete. Social vehicles, especially heavy vehicles, will not only squeeze the track when they pass, but also cause damage to the road around the track. At the same time, the vibration when the train passes is also causing this damage. However, in the traditional pavement method, there are weak links in the pavement structure due to the existence of fasteners and damping materials in the pos...

AI Technical Summary

Problems solved by technology

In the traditional pavement method, there are weak links in the pavement structure due to the existence of fasteners and damping materials in the position of track fasteners.
