Abstract

The single-layer all-interchange overpass is a kind of overpass structure with simple structure, small engineering quantity and low cost. The straight traffic in the two directions of the main road (A) all passes through the crossing through the linear viaduct (A1); the secondary main road ( B) Straight traffic in the above two directions crosses the main road through the curved viaduct (C) outside the starting point of the viaduct on the main road, and then gets off the bridge to the opposite road; the two left-turning lanes on the main road, Both go on the bridge in parallel with the straight lane, and then turn around to the curved viaduct (C) beyond the other starting point of the straight viaduct on the main road, and turn left after crossing the main road (A); Turning lanes are all parallel to the same straight lane on the bridge, and then pass through the curved viaduct (D) outside the starting end of the main road and the opposite secondary road, and cross the main and secondary roads to realize the left turn and pass through the intersection; the main and secondary roads The four right-turning lanes on the road are all parallel to the straight lanes on the bridge, and then turn right and get off the bridge.

Description

Single-story full-interchange overpass

technical field

The utility model relates to a single-layer overpass at an urban road intersection, which belongs to the field of urban traffic.

Background technique

With the increase of urban population and the increase of the number of cars, urban traffic is becoming more and more congested, even jammed. This kind of congestion and jam mainly occurs at intersections, resulting in waste of time and frequent accidents, and brings new problems to people. Trouble, in order to solve this problem, overpasses are set up at intersections. However, these overpasses either occupy a large area, have many floors, require a large amount of engineering, and are expensive to build. They will cause huge damage to the urban landscape and are difficult to implement at urban crossroads. or not possible at all. Either it can only ensure that the straight line of the main line is unimpeded, and the straight line in other directions merges with the turning, which does not fundamentally solve the traffic jam phenomenon at the intersection, and even often leads to collision accidents.

Contents of the invention

Technical problem: the purpose of this utility model is to provide a kind of single-layer (or half-layer) all-interchange overpass, all motor vehicles all travel on the bridge, personnel and non-motor vehicles walk on the ground, both do not interfere with each other, do not need traffic lights Unimpeded. The overpass bridge is built above the original road, does not occupy other places, occupies a small area, and the height of the overpass bridge from the ground is only one floor (or even half a floor), which has little impact on the urban landscape. The present invention has simple structure, small engineering quantity and low cost.

Technical solution: The motorway of the utility model is in the shape of a "ten" and has only one floor (or half a floor). Straight vehicles in both directions on the main road pass through the intersection through a linear viaduct, and two directions on the secondary road pass through the crossing. The straight lanes of the road pass the crossing through the curved viaduct beyond the starting end of the viaduct on the main road, and then get off the bridge to the opposite road.

The two left-turning lanes on the main road go up the bridge in parallel with the straight-going lane, and then circle around to the curved viaduct beyond the starting part of the other end of the straight-going viaduct. After crossing the main road, get off the bridge and turn left intersection.

The two left-turning lanes on the secondary arterial road are both parallel to the same straight lane on the bridge, and then pass through the curved viaduct beyond the starting end of the main road bridge and the opposite secondary arterial bridge to cross the main road and the secondary arterial road to realize the left turn through the intersection.

The four right-turning lanes on the main and secondary arterial roads all go up the bridge in parallel with the straight lane, and then turn right and get off the bridge.

When the sidewalk below the overpass and the non-motorized vehicle road surface elevation were lower than the adjacent road surface elevation, then the height of the one-story overpass was just less than one floor (actually a half-story overpass).

Beneficial effects: the utility model provides a single-layer (or half-layer) full-interchange overpass, all motor vehicles drive on the bridge, personnel and non-motor vehicles walk on the ground, the two do not interfere with each other, and traffic lights are not used without hindrance . The overpass bridge is built above the original road, does not occupy additional space, occupies a small area, and the height of the overpass bridge from the ground is only one floor (or even half a floor), which has little impact on the urban landscape. The utility model has simple structure, small engineering quantity and low cost .

Detailed ways

With reference to the accompanying drawings, for the convenience of description, the following descriptions all assume that the direction in the figure is: up north, down south, left west, right east.

The entire overpass is in the shape of a "ten" with only one or half floors. Straight vehicles in both directions of the main road A pass through the intersection through the straight viaduct A1; straight vehicles in both directions on the secondary trunk road B are all Cross the main road A by turning around to the curved viaduct C outside the starting end of the main road viaduct, and then get off the bridge to the opposite road; the two left-turning lanes on the main road A are parallel to the straight lane and go up the bridge, and then Turn outside to the curved viaduct C other than the other starting point of the straight viaduct on the main road, and turn left after crossing the main road A to pass through the intersection; Through the curved viaduct D beyond the starting end of the main road A and the opposite secondary road B, cross the main and secondary roads to realize a left turn and pass through the intersection; the four right-turning lanes on the main and secondary roads are all parallel to the straight lane Bridge, then turn right off the bridge;

The pavement elevations of pedestrian roads and non-motor vehicle roads under the overpass are lower than those of adjacent roads.

The straight fourth lane 4 of the main road A is from west to east, on the west side from the curved viaduct C located outside the starting end of the main road viaduct, the curved viaduct D across the main and secondary arterial roads (the seventh lane 7, the third lane 3, The sixth lane 6) Pass through the straight viaduct A1 on the main road, get off the bridge and then from the east side to the curved viaduct C outside the starting end of the viaduct on the main road, and the curved viaduct D across the main and secondary arterial roads (the eighth lane 8 , the first lane 1, the fifth lane 5) pass through below; the second straight lane 2 of the main road A is from east to west, and the fourth straight lane 4 of the main road A is the same.

The first straight lane 1 of secondary trunk road B is from south to north, passing under the curved viaduct D (seventh lane 7) crossing the main and secondary trunk roads on the south side, entering the viaduct lane uphill, and crossing the east side on the bridge After the main road A (the fourth lane 4, the second lane 2, the sixth lane 6, and the tenth lane 10), it starts to go downhill, turns to the secondary road B to the north, and crosses the main and secondary roads from the curved viaduct D (fifth Lane 5) passes under; the straight third lane 3 of secondary trunk road B is from north to south, similarly the straight first lane 1 of secondary trunk road B.

Turn right (from south to east) on secondary trunk road B from north to ninth lane 9, cross the upper bridge under the curved viaduct D (seventh lane 7) that crosses the main and secondary trunk roads, turn right along the lane, and then go downhill and enter the east direction; The eleventh lane 11 of the secondary trunk road B turns right from south (from north to west), similarly the eleventh lane 11 of the secondary trunk road B turns right from north (from south to east).

Secondary road B turns north to left (from south to west).
