Overpass for T road

Abstract

Provided is an overpass for a T road. The T road comprises a transverse main road and a longitudinal main road which intersect in a T shape, wherein the transverse main road comprises a left running A lane and a right running B lane, the longitudinal main road comprises an up running C lane and a down going D lane, and a bridge body is arranged on the T road. The overpass for the T road is characterized in that the bridge body comprises a first ring road bridge for the A lane to turn to the D lane and a second ring road bridge for the B lane to turn to the C lane. The overpass for the T road is simple in structure, small in floor area, easy to identify direction, not prone to make mistakes and free of traffic lights. The length of the ring road bridges are greatly shortened, and building cost is saved. Compared with a traditional overpass, the overpass for the T road is obviously different in structure, and effects are obviously improved.

Description

technical field [0001] The invention relates to an overpass, in particular to an overpass suitable for T-shaped intersections. Background technique [0002] With the improvement of social and economic level, the number of cars is gradually increasing, and the traffic pressure is also increasing. Now the roads are becoming more and more congested, and even blockages are prone to occur. This kind of blockage mainly occurs at intersections, resulting in waste of time and frequent accidents. Happened and brought troubles to people's lives. [0003] Under normal circumstances, in order to reduce traffic pressure, people will build overpass bridges at traffic hub intersections. The overpass bridges generally adopt a winding-span structure, that is, an elevated ramp that bypasses the main road to another main road is built on one side of the main road. However, this This kind of span-around structure is destined to have a large enough radian and height. Therefore, the span-around ...

[0002] With the improvement of social and economic level, the number of cars is gradually increasing, and the traffic pressure is also increasing.

[0003] Under normal circumstances, in order to reduce traffic pressure, people will build overpass bridges at traffic hub intersections. The overpass bridges generally adopt a winding-span structure, that is, an elevated ramp that bypasses the main road to another main road is built on one side of the main road. However, this This kind of span-around structure is destined to have a large enough radian and height. Therefore, the span-around overpass covers a large area and requires a large amount of engineering. If it is installed at a simple T-shaped intersection, it will undoubtedly be a huge waste of resources; The direction of the elevated ramp of the span overpass is difficult to identify, which can easily cause drivers to go in the wrong direction, wasting time and energy
