Description

Technical Field

[0001] The present invention relates to the technical field of overpasses, and particularly to an interchange roundabout overpass. Background Art

[0002] The full name of an overpass is "grade separation bridge", which refers to a modern bridge built at the intersection of more than two intersecting roads, with upper and lower layers and multi-directional non-interference. Due to the high construction cost, it is usually only built at the interchange of expressways, urban arterial roads or expressways. Its main function is to enable vehicles in all directions to pass quickly without being controlled by traffic lights at intersections.

[0003] There are usually two solutions for existing road intersections: one is that the upper and lower layers of the road are grade-separated and do not communicate with each other. This method has a fast passing speed, but it is impossible to change lanes between the upper and lower layers; the other is that there are various interchange overpasses at the grade-separated intersection of the upper and lower layers of the road, such as cloverleaf overpasses, etc. These overpasses generally have a large floor area, many layers, large engineering quantities, and high costs. Most of them ensure that the main line goes straight without obstruction, and the straight vehicles in other directions will intersect with turning vehicles, and the problem of interchange has not been well solved. There is also a roundabout overpass that solves the problem of large floor area, etc., but the vehicles in the roundabout drive slowly, and it is easy to form vehicle congestion. In addition, there are four exits in the roundabout, resulting in the intersection of vehicle driving routes, and it is very easy to have traffic accidents. Therefore, we propose an interchange roundabout overpass to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art and propose an interchange roundabout overpass.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An interchange roundabout overpass includes an upper-layer two-way through lane and a lower-layer two-way through lane. The upper-layer two-way through lane includes two upper-layer auxiliary bridges and two upper-layer downward left-turn auxiliary lanes. The two upper-layer auxiliary bridges are respectively connected to both sides of the upper-layer two-way through lane, and the two upper-layer downward left-turn auxiliary lanes are respectively connected to the inner sides of the two upper-layer auxiliary bridges;

[0007] The lower-layer two-way through lane includes two lower-layer auxiliary lanes and two lower-layer upward left-turn auxiliary lanes. The two lower-layer auxiliary lanes are respectively connected to both sides of the lower-layer two-way through lane, the two lower-layer upward left-turn auxiliary lanes are respectively connected to the two lower-layer auxiliary lanes, and the two lower-layer upward left-turn auxiliary lanes are connected to the two upper-layer auxiliary bridges. The two upper-layer downward left-turn auxiliary lanes are connected to the two lower-layer auxiliary lanes;

[0008] On both sides of the upper - layer two - way straight - through lane, there are two upper - layer down - going right - turn auxiliary lanes, and the two upper - layer down - going right - turn auxiliary lanes are connected to both sides of the lower - layer two - way straight - through lane. On both sides of the lower - layer two - way straight - through lane, there are two lower - layer up - going right - turn auxiliary lanes, and the lower - layer up - going right - turn auxiliary lanes are connected to the upper - layer two - way straight - through lane.

[0009] Preferably, the number of lanes of the upper - layer two - way straight - through lane and the lower - layer two - way straight - through lane is eight, which can increase the traffic capacity of vehicles.

[0010] Preferably, green belts are arranged on both sides of the upper - layer two - way straight - through lane and the lower - layer two - way straight - through lane, which can improve the traffic environment.

[0011] Preferably, guardrails are arranged in both the upper - layer two - way straight - through lane and the lower - layer two - way straight - through lane. The guardrail includes a plurality of columns. Arc - shaped groove plates are fixedly installed on both sides of the plurality of columns. Clamping plates are fixedly installed on both sides of the plurality of columns. A clamping groove is arranged at the top of the clamping plate. The inner wall of the clamping groove and the inner wall of the arc - shaped groove plate are clamped with the same connecting column. A guard plate is fixedly connected to the side of the plurality of connecting columns close to each other. A limiting component for limiting the connecting column is arranged at the top of the arc - shaped groove plate, which can separate vehicles traveling in different directions.

[0012] Preferably, the limiting component includes a sliding groove arranged at the top of the arc - shaped groove plate. A slot hole is arranged on the bottom inner wall of the sliding groove. A clamping column is slidably connected in the slot hole, and one end of the clamping column extends to the top of the connecting column. One end of the clamping column is attached to a spring, and one end of the spring is attached to one side of the column. A push rod is fixedly installed at the top of the clamping column, and the top end of the push rod penetrates through the sliding groove and extends to the outside of the arc - shaped groove plate.

[0013] Preferably, reflective materials are coated on both sides of the guard plate, which can give a prompt to passing vehicles.

[0014] Preferably, a base is fixedly installed at the bottom end of the column to support the column.

[0015] Preferably, no - crossing traffic sign lines or isolation belts are arranged in both the upper - layer two - way straight - through lane and the lower - layer two - way straight - through lane.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the present invention, in the upper - layer two - way straight - through lane, vehicles that need to turn right turn right through the upper - layer down - going right - turn auxiliary lane; vehicles that need to turn left turn left through the upper - layer access bridge, the upper - layer down - going left - turn auxiliary lane and the lower - layer auxiliary lane; vehicles that need to make a U - turn pass through the upper - layer access bridge, the upper - layer down - going left - turn auxiliary lane, the lower - layer up - going left - turn auxiliary lane and the upper - layer access bridge in sequence to make a U - turn.

[0018] 2. In the present invention, for the vehicles in the lower-level two-way through lanes, the vehicles needing to turn right pass through the lower-level upward right-turn auxiliary lane to turn right. For the vehicles needing to turn left, they pass through the lower-level auxiliary lane, the lower-level upward left-turn auxiliary lane, and the upper-level attached bridge to turn left. For the vehicles needing to make a U-turn, they sequentially pass through the lower-level auxiliary lane, the lower-level upward left-turn auxiliary lane, the upper-level attached bridge, the upper-level downward left-turn auxiliary lane, and the lower-level auxiliary lane to make a U-turn.

[0019] 3. In the present invention, when a traffic accident occurs in the upper-level two-way through lane or the lower-level two-way through lane, the push rod is pushed to drive the clamping column to move, and the limit on the connecting column is released. The protective plate is moved upward, and the protective plate drives the connecting column to move upward. The movable column is moved to the oncoming lane, and with the traffic marking lines or isolation belts configured, the lane is partitioned, and thus the vehicle passing problem can be well solved.

[0020] 4. The upper-level attached bridge, the upper-level downward left-turn auxiliary lane, the lower-level auxiliary lane, and the lower-level upward left-turn auxiliary lane in the present invention form a virtual roundabout. Motor vehicles can complete operations such as turning left, turning right, and making a U-turn through the virtual roundabout, improving the vehicle passing efficiency.

[0021] 5. In the present invention, the number of lanes in the upper-level two-way through lane and the lower-level two-way through lane is eight, which can increase the vehicle passing capacity. Green belts are provided on both sides of the upper-level two-way through lane and the lower-level two-way through lane, which can improve the traffic environment.

[0022] The structure of the present invention is simple. Vehicles complete left turns, right turns, and U-turns through the upper-level downward right-turn auxiliary lane, the lower-level upward right-turn auxiliary lane, the upper-level attached bridge, the upper-level downward left-turn auxiliary lane, the lower-level upward left-turn auxiliary lane, and the lower-level auxiliary lane. And when a traffic accident occurs, the oncoming lane is borrowed through the guardrail to solve the vehicle passing problem, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
