Description

A low-profile overpass at a crossroad

technical field

The utility model relates to the technical field of road and bridge construction, in particular to a low crossroad overpass.

Background technique

With the development of the city, the number of cars has increased rapidly, which has brought great pressure to the traffic in the city. The current traffic bridges can no longer solve the pressure of traffic congestion. On the one hand, there are many and dense traffic lights at each intersection, which makes the vehicles travel slowly. , causing serious rear congestion; on the other hand, traffic jams and traffic accidents often occur at intersections where pedestrians and motor vehicles cross and grab lanes.

In order to solve the defects of traffic lights, many cities build viaducts to relieve traffic pressure, but the existing viaducts only stand in the perspective of motor vehicles and solve how to make motor vehicles pass through the intersection quickly. The existing viaducts are divided into many layers. The height of each floor of this kind of viaduct is more than 4.5 meters, not only the structure is complex, the floor area is large, but also the construction is more troublesome, the construction project is relatively large, and too much construction time is wasted. After being put into use, this viaduct has no Practical consideration of how pedestrians pass through the crossroads, some crossroads build overpasses near the viaducts to meet the needs of pedestrians. The bottom of the overpass is for motor vehicles and pedestrians on the bridge. Therefore, the height of such overpasses is generally above 4.5 meters. , which leads to a larger slope of the overpass. In order to reduce the slope of the ramp, the length of the ramp can only be increased, so that the length of the ramp is close to 100 meters. For pedestrians, crossing the bridge consumes too much energy and is not Practical, poor practicality.

Utility model content

In order to solve the problems of existing viaducts such as complex structure, high bridge body height, large floor area, and high cost, and this kind of viaduct does not take into account the practicality of pedestrian traffic and has poor practicability, the utility model The purpose of the invention is to provide a low-slung crossroad overpass with a relatively low bridge body, no influence on the city appearance, low construction cost, small occupied area, and convenient passage of vehicles and pedestrians.

In order to achieve the above object, a low-profile overpass at a crossroad is provided in an embodiment of the utility model, which includes a viaduct spanning the longitudinal road surface. Horizontal pedestrian passages and vertical pedestrian passages are respectively built on both sides of the road, and the horizontal and vertical pedestrian passages and the horizontal and vertical pedestrian passages are connected by right-turn lanes, which are located at the four corners of the "ten" intersection. , and the right turn lane is level with the ground level,

Among them, the right-turn lane is divided into the right-turn lane for vehicles and the right-turn lane for pedestrians through the divider.

The overpass bridge provided by the utility model is simple in structure, and the overall planning is more reasonable. Both motor vehicles and non-motor vehicles have their own driving lanes, and non-motor vehicles and motor vehicles will not cross the road at the intersection, so the overpass will not In the event of traffic jams, the longitudinal pedestrian passage of the overpass is basically flush with the ground level, which saves time and effort for pedestrians to cross the street longitudinally. Fast straight ahead, right turn and left turn for bullet trains. Ingenious structural design, strong practicability, low cost, easy to promote

Further, both ends of the longitudinal pedestrian passage are flush with the ground plane, and the part of the longitudinal pedestrian passage crossing the viaduct is provided with a downwardly recessed pedestrian recess. In this technical solution, the structural design of both ends of the longitudinal pedestrian passage is flush with the ground plane, which is truly people-oriented. Pedestrians do not need to pass through the overpass or underground passage to cross the street, saving time and effort. The structural design of the road ensures that in the case of a low viaduct, in order to allow pedestrians to pass through the bottom of the bridge, the pedestrian passage needs to be recessed downward.

Further, the height of the viaduct from the ground level is 1.5m, the vertical height of the viaduct from the driving concave road surface is 4.5m, and the vertical height of the viaduct from the pedestrian concave road surface is 2.5m. In this technical solution, the height of the viaduct, the height of the driving concave road from the viaduct and the vertical height of the pedestrian concave road from the viaduct are further limited. The height of the viaduct is 1.5m, which does not affect the appearance of the city. The smaller the size, the lower the cost, and it is easy to promote. Motor vehicles will not consume too much power when passing through the viaduct. In addition, the vertical height between the top of the viaduct and the concave road surface is 4.5m, which can completely realize that any vehicle below 4.5m can pass under the bridge. , to ensure the normal passage of vehicles at the intersection. In addition, the vertical height between the top of the viaduct and the pedestrian concave road surface is 2.5m, which means that the distance between the pedestrian concave road and the ground level is 1 meter. Motor vehicle traffic, strong practicability.

Further, the pedestrian recess under the viaduct is connected with the horizontal pedestrian passage on the viaduct through walking steps. In the technical solution, the pedestrian steps connect the pedestrian passage under the bridge with the pedestrian passage on the bridge, which is more convenient for pedestrians to pass, and improves the practicability of the viaduct.

Further, the overpass is also connected to four arc-shaped roads that are flush with the ground plane for connecting the transverse traffic lane and the longitudinal traffic lane, and the arc-shaped roads are located outside the right-turn lane. Through the curved road, the vehicle can go straight through the intersection and then turn through the curved road, and then realize the left turn of the vehicle, which is convenient to drive and will not cause traffic congestion. The curved road can also be replaced by the nearby small street.

Preferably, guiding guardrails are provided at the joints of the transverse and longitudinal traffic lanes, right-turn lanes and arc lanes. In the technical solution, the function of the guiding guardrail is firstly to be used as a road sign, and also to ensure the safety of right-turning vehicles.

Preferably, guardrails are provided on both sides of the viaduct. The installation of guardrails on the viaduct can ensure the safety of vehicles on the bridge body and pedestrians under the bridge, and prevent accidental falls.

The beneficial effects of the utility model are: the overpass is a low-profile overpass, which not only has a simple structure and low cost, but also occupies a small area, does not need traffic light control, avoids vehicles rushing at the crossroads, and truly realizes motor vehicles and non-motor vehicles. The fast straight, right and left turns improve the mobility of urban vehicles and avoid traffic jams. There are special passages for pedestrians crossing the street, saving time and effort, strong practicability, low cost, and easy to promote.
