Definitions
- the present invention relates to urban road structures, particularly to urban intersection structures. Background technique
- intersections of cities mainly adopt road structures such as plane crossings, roundabouts, viaducts, multi-level overpasses, and high clearance tunnels.
- these existing road structures have defects of one kind or another, which cannot effectively solve the traffic jam problem in the city.
- traffic lights For intersections with plane intersections, it is necessary to use traffic lights to control the passage of each lane in turn, to concentrate the vehicles and then release them, which makes the intersections easily clogged, and the driver rushes to grab the lamp position in order to compete for time. Lights are prone to accidents such as rear-end collisions or line collisions, causing serious damage such as personal injury and car damage.
- the object of the present invention is to provide a city crossroad structure which can effectively solve the problem of traffic jam.
- the crossroad structure can significantly reduce the residence time of the vehicle at the intersection, and has less capital investment, less engineering quantity and short construction time.
- the main technical solutions adopted by the present invention are: a city crossroad structure for solving traffic jam problems, including a crossed first trunk road and a second trunk road, the first trunk road and the second trunk road are two-way lanes, the first trunk road and the second road
- the surface pavement of the main road forms a central platform at the intersection where the surface of the road surface is shared.
- the first main road has a low-rise tunnel passing through the underground of the central platform.
- the traffic height of the low-rise tunnel is not less than 2 meters. No more than 3 meters, the low-rise tunnel rises from the underground through the central platform and then rises back to the surface. From the outer side of the low-speed tunnel, an over-the-road turning tunnel is drawn.
- the traffic height of the overpass turning tunnel is neither Below 2 meters and not more than 3 meters, the over-the-road turning tunnel turns from the front of the uplifting section of the low-rise tunnel. After a section of turning and lifting the slope, it is connected with the second trunk in the same direction.
- the surface of the first trunk road Divided into low-lying tunnels into two left and right roads with opposite driving directions for large vehicles.
- the two surface lanes are in the central plane.
- the on-stage connection forms two U-turn lanes with opposite U-turn directions for large vehicles to turn around.
- the two U-turn lanes are located on the left and right sides of the straight lane occupied by the second main road on the central platform, and the road surface on the first main road is driven.
- the outer side of the direction leads to a lane that turns to the outer side of the second main road, and a lane that turns to the outer side of the first main road is drawn on the outer side of the driving direction of the second main road.
- the present invention may also adopt the following subsidiary technical solutions.
- the vehicle passing height of the low tunnel is 2.50-2.60 meters.
- the vehicle passing height of the low tunnel is formed by the depth of the bottom surface of the tunnel and the height of the top subgrade of the tunnel.
- the vehicle passing height of the over-the-road turning tunnel is 2.50-2.60 meters.
- the vehicle passing height of the over-the-road turning tunnel is composed of a sinking depth of the bottom surface of the tunnel and a lifting height of the top subgrade of the tunnel.
- An underground walkway is disposed on the first main road, and an escape door is disposed between the underground walkway and the underground U-turn portion of the over-the-road turning tunnel.
- a ventilation window is provided at the top of the underground walkway of the first main road.
- a ventilation window is provided at the top of the over-the-road turning tunnel.

- the middle and low-rise tunnels form a fast line for trolleys, which can effectively avoid large vehicles taking up fast-track driving and slowing down driving speed.
- the large-scale small-sized vehicles that travel on the first trunk road can directly pass through the second tunnel through the low-rise tunnel, and all the U-turn vehicles traveling on the first trunk road can smoothly and safely turn over the central platform.
- Vehicles do not need to be controlled by traffic lights, nor will they affect vehicles in other directions, which not only makes the vehicles on the first trunk road smoother, but also shortens the green light passage time of large vehicles allocated to the first trunk road, making the first trunk road and the second road.
- the traffic on the main road has become smoother.
- the low-vehicle tunnels and over-the-road turning tunnels used in the present invention have a traffic height of no more than 3 meters, which can significantly reduce the construction amount and shorten the construction time. , cost less.
- the vehicle traffic height is formed by the tunnel bottom sinking depth of the tunnel and the top subgrade lifting height of the tunnel.
- This semi-sinking and semi-lifting tunnel structure further reduces the depth of ground subsidence required for excavation of low-rise tunnels, avoids encountering groundwater, and makes the foundation pile easier to construct. It can be treated with simple cofferdams, effectively reducing construction.
- the time, the construction cost is greatly reduced, the broken pieces of the original road surface, the hard sand excavated, the soil can be mixed into the concrete, and the cushion is used to fill the rising part of the road surface, without having to remove all the excavated soil. , reduce construction The impact of heavy transport vehicles on traffic during the period. Furthermore, reducing the depth of the ground sinking is also conducive to the migration and reconstruction of the sewer.
- the vehicle passing height of the over-the-road turning tunnel is not more than 3 meters, and the vehicle passing height is common to the sinking depth of the bottom surface of the tunnel and the lifting height of the top subgrade of the tunnel.
- a raised rainwater separation zone is provided on the ground at the entrance and exit of the low-rise tunnel, thereby blocking a large amount of rainwater from flowing into the low-rise tunnel through the lane, which not only prevents vehicle traffic Blocked by water, and reduced the workload of the pump.
- the invention is applicable to cities in all developed countries, and is particularly suitable for the general transformation of crossroads where the number of small cars on the road leads to traffic congestion, so that more intersections can be opened with limited resources, without expanding Wide road surface can achieve the effect of increasing urban traffic roads.
