Abstract

A combined overpass without barriers for pedestrians and vehicles at the intersection of a main road and a branch road relates to a combined traffic facility of road traffic at the intersection of the main road and the branch road. In order to solve the problems of inconvenience for pedestrians and vehicle congestion caused by the fact that pedestrians and vehicles compete with each other on the same road and traffic lights are arranged for waiting for traffic restriction on the main road and the branch road of urban road traffic, the sidewalks (5) on the main road and the branch road are arranged on the same horizontal plane and are all-directionally communicated by the bidirectional sidewalk (6) crossing the main road (1), so that people and vehicles are shunted to ensure that the pedestrians walk conveniently and safely without being interfered by vehicles; arranging an arc-shaped bridge (4) of a main road (1) of a main road and branch road cross section to ensure that straight vehicles of the main road (1) pass through without barriers; the annular overpass (3) is arranged at the section of the main road and the branch road, so that vehicles turning around on the main road (1) and motor vehicles on the branch road (2) can be ensured to turn around in all directions without barriers and pass in the selected direction.

Description

Barrier-free combined overpass for pedestrians and vehicles at the intersection of main and branch roads

technical field

It relates to a pedestrian and vehicle barrier-free combined overpass at the intersection of main and branch arterial roads, which relates to road traffic.

Background technique

The use of automobiles in road traffic operation is increasing day by day, and the existing road traffic facilities can not keep up with the development, which makes some main and branch road intersections difficult to pass, and vehicle congestion is very serious. Nowadays, road traffic mostly uses a single overpass, cross bridge or tunnel to solve the problem of traffic congestion, and people and vehicles compete for the road, and traffic lights are set to limit traffic, which greatly reduces the efficiency of road traffic and even brings many safety hazards; or use pedestrian bridges or It is a pedestrian underpass, which brings great inconvenience to pedestrians crossing the road. The safety hazards caused by motor vehicle congestion in urban road traffic and the main position of people in road traffic have attracted more and more attention from the society.

Contents of the invention

The technical problem to be solved by the present invention is to design a barrier-free combined overpass bridge for pedestrians and vehicles at the intersection of main and branch roads, so that the diversion of pedestrians and vehicles no longer competes for the same road, and there is no traffic light waiting limit, so as to ensure that pedestrians and vehicles are barrier-free in all directions pass. Pedestrians always walk on the same ground level and are not disturbed by vehicles; vehicles have priority to go straight, and the curves are smooth.

In order to solve the problems in the above-mentioned road traffic, the present invention has designed such a pedestrian and vehicle barrier-free combined overpass of main and branch road intersections: comprising trunk roads and branch roads, said trunk road and branch roads Merge into an intersection. Sidewalks are arranged on both sides of the main road and branch roads, and the sidewalks are located on the same ground level; the main road is provided with an arc bridge at the cross section; There is also a circular overpass on the upper level.

The sidewalk is located at the intersection of the main road and the branch road, and a two-way sidewalk is provided under the arc-shaped bridge arch hole to run through it in all directions.

The arc-shaped span bridge of the main road is two-way and four-lane, providing barrier-free passage for straight vehicles on the main road.

The ring-shaped overpass of the main road is a two-way lane in the same direction, which are respectively the outer ring lane for right-turning vehicles and the inner ring lane for left-turning vehicles. Straight ring structure, the ring-shaped overpass is provided with a plurality of on-ramps and off-ramps, the entrances and exits of the on-ramps and off-ramps are respectively set on the outermost motorway of the main road and the motorway of the branch road.

After adopting the above-mentioned pedestrian and vehicle barrier-free combined overpass structural facilities at the intersection of main and branch roads, it can realize the diversion of pedestrians and vehicles without competing for the same way, and there is no traffic light waiting limit, which ensures the barrier-free all-round passage of pedestrians and vehicles and reduces road traffic. Congestion, especially urban road traffic congestion and the resulting safety hazards, improve the efficiency of road traffic. Optimize the road traffic structure and reduce the occupied area. Open a smooth road for the urban "car family"; open the door of convenience and safety for pedestrians and "cyclists". It embodies the new concept of humanistic care and harmonious transportation.

Detailed ways

As shown in Figure 2, the main road 1 and the branch road 2 meet to form a crossing section, and both sides of the main road 1 and the branch road 2 are provided with sidewalks 5, and between the sidewalks 5 on both sides of the road are motor vehicles. Lane (in the figure, the main road is two-way six-lane, and the branch road is two-way four-lane, which can also indicate the increase or decrease of the road condition). The sidewalk 5 is set up on the same ground level at the cross section by the arc span bridge 4. Two-way sidewalk 6 all-round penetration.

Be located in trunk road 1 and be provided with a ring-shaped overpass 3 on the upper floor of the sidewalk 5 in the crossing section, the two ends of the ring-shaped overpass 3 are semicircular bridge bodies that are long straight ring structures; the two ends of the ring-shaped overpass 3 are semicircular The inner semicircle chord length of the shape is slightly greater than the width of the arc bridge 4, and the outer semicircle chord length is slightly greater than the total width of the trunk road 1; Buffer distance, so that the uphill and downhill vehicles of the arc-shaped span bridge 4 pass under the ring flyover 3; the ring flyover 3 is 5.3 meters away from the sidewalk 5 road surface height (the height limit standard of the first-class highway, and different height limits can also be set according to road conditions) ; The ring-shaped overpass 3 is the same direction dual-lane, wherein the outer ring lane 3a is for right-turning vehicles, and the inner ring lane 3b is for left-turning vehicles; On the intersection of road 2 motor vehicle lanes, an entrance ramp 3c and an exit ramp 3d are respectively provided. The entrance ramp 3c is used for turning vehicles of the main road 1 or motor vehicles of the branch road 2 to drive into the ring-shaped overpass 3, and the described exit ramp 3d is for the ring-shaped overpass 3d. On the overpass, the right-turning vehicle drives out in a selected direction, and the uphill and downhill sections of the entrance ramp 3c and exit ramp 3d are standard gradients.

Located on the main road 1, an arc-shaped span bridge 4 is provided at the intersection section. The arc-shaped span bridge 4 provides barrier-free passage for straight vehicles on the trunk road 1. The arc-shaped span bridge 4 is a two-way four-lane bridge. The bridge arch hole is not less than 2.6 meters from the effective height of the road surface across the sidewalk 6, and the up and down slope sections of the curved cross bridge 4 are standard slopes.

The sidewalk 5 located at the intersection section is connected in all directions by the two-way sidewalk 6 crossing the main road 1 under the arc bridge 4. The sidewalk 6 crossing the main road 1 is two-way and two-way wide, so that pedestrians can walk freely and safely on the road. intersection.
