Technical Field

The invention relates to the field of railway construction, in particular to a light rail structure for urban pavements.

Background

Railways are commonly used in urban traffic, subways and light rails are applied, urban rail transit vehicles in some cities not only can be used for subways, but also can be used for light rails, and the light rails run on the road surface, so that the construction of the rails is particularly important, the comfort is met, and meanwhile, pedestrians on the road surface are guaranteed to walk, which is difficult to be done by the traditional rails.

Disclosure of Invention

The invention aims to solve the technical problem of providing a light rail structure for urban pavements, and effectively overcomes the defects of the prior art.

The technical scheme for solving the technical problems is as follows:

a light rail structure for urban pavements comprises a roadbed and at least one group of rails, wherein upward kerbs are respectively arranged at the upper ends of two sides of the roadbed along the road direction, grooves are formed between the kerbs on two sides and the upper surface of the roadbed, a first basic layer is laid in each groove, a groove-shaped depressed area is arranged in the middle of the upper end of the first basic layer along the road direction, a second basic layer is laid in each depressed area, a shockproof buffer layer for separating the first basic layer from the second basic layer is arranged between the contact surfaces of the first basic layer and the second basic layer in a clamping mode, a rail depressed area corresponding to each rail is arranged at the upper end of the second basic layer along the road direction, each rail is arranged in the corresponding rail depressed area along the road direction, and a pavement layer is laid on the upper surfaces of the first basic layer and the second basic layer in the area except the rail depressed area.

On the basis of the technical scheme, the invention can be further improved as follows.

Further, the upper surfaces of the first base layer and the second base layer are flush and are positioned on the same horizontal plane.

Further, the upper surfaces of the first base layer and the second base layer are flush and are positioned on the same horizontal plane.

Further, the shockproof buffer layer is a shockproof pad, and two ends of the shockproof buffer layer are respectively folded and fixed on the upper surface of the second base layer.

Further, the surfaces of both sides of the crash pad are uniformly distributed with stripe textures, and the surfaces of the corresponding concave regions, the bottom surface of the second base layer and the side surfaces of both sides are rough surfaces.

Further, the upper surface of the pavement layer is flush with the upper end of the curb.

Further, the pavement layer is an asphalt layer or a stone brick layer.

Further, the upper surfaces of the kerbs are all inclined surfaces which are inclined outwards and extend downwards, and the highest positions of the upper surfaces of the kerbs are flush with the upper surfaces of the pavement layers.

Further, the curb, the first foundation layer and the second foundation layer are all concrete pouring members.

Further, the side walls of the two sides of the recessed area extend from bottom to top in an inclined manner towards the upper part of the middle of the recessed area, and the surfaces of the two sides of the second base layer are inclined planes which are parallel to the side walls of the two sides of the recessed area.

Furthermore, the recessed area of the rail is filled with a fixed block, and the lower end of the rail is embedded in the corresponding fixed block.

The invention has the beneficial effects that: whole design makes the road surface flat, makes things convenient for people's walking, also is favorable to going of vehicle, and is multi-purpose all the way, and simultaneously, the buffer layer that takes precautions against earthquakes is favorable to reducing the impact of light rail vehicle to ground, has also reduced the noise that the vehicle produced when going the process when promoting passenger's travelling comfort.
