Technical Field

The invention belongs to the technical field of urban road traffic, and relates to a ramp, in particular to an underground road access.

Background

With the rapid development of urban construction and the explosive growth of automobile holding capacity in China, the problem of urban road traffic jam is increasingly serious, so that a large number of large and medium cities have 'morning and evening peaks', a large amount of traffic flow rushes from a living area to a working area in the morning peak 'and people flow and traffic flow rushes from the working area to the living area in the evening peak', and the traffic jam in one passing direction and the smooth asymmetric traffic jam in the opposite direction are caused.

Many cities are usually relieved by constructing viaducts in order to solve traffic congestion, but since urban land resources are seriously short in recent years and viaducts occupy a large amount of land resources, many cities begin to construct underground roads. Because the ramp at the entrance and exit of the underground road is generally arranged at the center of a distributed point with busy urban traffic, the phenomenon of 'long queue' is easy to appear at the entrance and exit of the underground road when the road is congested at the morning and evening peaks, the traffic of the overground road is influenced, the congestion of the underground road is also caused, and the controllable entrance and exit of the underground road are not easy to realize.

Because the existing gateway is mainly an open gateway, the arrangement of the gateway can occupy ground resources and reduce the traffic capacity of roads on the ground.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention aims to provide an underground road access so as to achieve the purposes of relieving traffic jam, controlling the access of underground roads and not occupying ground resources.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: an underground road access comprises an above-ground road, an underground road, an access opening, a slope for connecting the above-ground road and the underground road, wherein the access opening is arranged on the above-ground road and penetrates through the above-ground road, the slope is arranged along the road driving direction, and the underground road access further comprises a lifting ramp for driving vehicles or accessing the underground road; a groove matched with the lifting ramp is formed in the slope; one end of the lifting ramp is hinged to one end, close to the slope, of the ground road, a lifting device used for lifting the lifting ramp is arranged at the bottom of the lifting ramp, the top of the lifting ramp is matched with the slope surface of the slope after the lifting ramp is landed, and the top of the lifting ramp is matched with the road surface of the ground road after the lifting ramp is lifted;

as a limitation of the present invention: a rainwater interception groove for intercepting rainwater is arranged on the slope;
