Urban overpass system

Abstract

The invention relates to an urban overpass system, belonging to that field of road and bridge construction, comprising a longitudinal motor vehicle straight lane and a transverse motor vehicle straight lane, At that junction of the straight lane of the longitudinal motor vehicle and the straight lane of the transverse motor vehicle, An underground platform is arranged on that bottom surface of theconcave pit, A surface platform is arranged directly above that underground platform, the above-ground platform is supported on the underground platform through upright columns, The space between thesubterranean platform and the aboveground platform is used to allow vehicles to pass through, A longitudinal motor vehicle straight lane is a part of that longitudinal motor vehicle drive into the lifting plate toward the above-ground platform and the underground platform, The part of vertical motor vehicles driving out of the above-ground platform and underground platform is vertical motor vehicles driving out of the lifting plate. Compared with the existing overpass system, the area occupied by the vertical motor vehicles is relatively small, the extension length is short, part of the overpass system is located underground, and the height from the ground is low, which greatly reduces the construction cost.

Description

technical field [0001] The invention relates to an urban overpass system, which belongs to the field of road and bridge construction. Background technique [0002] With the development of road construction and the needs of traffic, the rapid increase of urban population has led to an increasing number of vehicles, and road crossings at level crossings can easily cause vehicle congestion. Therefore, overpasses have become an excellent solution to traffic congestion. Although the overpass can relieve traffic congestion to a great extent, its disadvantages are also obvious: in order to have a sufficient height from the ground and at the same time not make the bridge surface too steep, the extension length of the overpass is relatively long, but for urban roads, generally There is not enough room for the extension of the overpass. Moreover, the construction cost of the overpass gradually climbs with the height of the overpass, and the existing overpass system costs a lot. Con...

Although the overpass can relieve traffic congestion to a great extent, its disadvantages are also obvious: in order to have a sufficient height from the ground and at the same time not make the bridge surface too steep, the extension length of the overpass is relatively long, but for urban roads, generally case and there is not enough room for the extension of the overpass

Moreover, the construction cost of the overpass gradually increases with the height of the overpass, and the existing overpass system costs a lot
