Description

Fishhook type rotary road traffic facility and construction method

The present invention relates to traffic road facilities and construction methods, and more particularly to traffic road facilities and construction methods at intersections. Background technique

The omnidirectional overpass that has been built or under construction in the world does not occupy an area of up to 100,000 square meters. It requires three or even four floors on the road to form a multi-level overpass with more than a dozen trails. The central area of the city is the most serious place for traffic jams, and it is most necessary to construct an omnidirectional overpass. The construction of a large area of the city center area requires the removal of a large number of roadside buildings. The total construction cost of each omnidirectional overpass is as high as several hundred million yuan or even more than one billion yuan. However, through multiple levels of crossover, although the floor space has been reduced, the cost of building bridges has increased significantly. In particular, the noise problems caused by driving and the fact that the bridges are too long make the buildings in the area around the overpass more inconvenient, and the commercial value of the buildings around the bridges is greatly devalued, thus losing the status of the commercial center.

The two ends of the turning road are respectively set on the left and right driving lanes of the secondary roads. It does not intersect with the straight-line cross-line connection (stereo cross), so that the straight-line cross-track will assume the two functions of straight-forward and turn-around; the slope of this straight-line cross-track has a slope of 3 to 20 degrees.

To achieve the second objective, the present invention provides a construction method of a hook-type rotary road traffic facility, which comprises the following steps in order to prevent traffic from being constructed:

A. First, expand the main roads at the intersection by 10 meters to 20 meters wide and 200 meters long for new roads, and then take part of the road to start construction of the hook-type rotary overpass A or the hook-type rotary tunnel A;

B. After the hook-type revolving overpass A or the hook-type revolving overpass tunnel A is completed, the new roads with temporary secondary trunk roads of 10 m to +20 m and 200 m long on both sides of the secondary main road are further widened. Let all the vehicles of the secondary trunk pass through the hook-type revolving bridge A or the hook-type revolving tunnel A to complete the straight or turn; then close the middle part of the secondary trunk to carry the straight overpass B or the underground straight tunnel B And the construction of the part of the pedestrian bridge R;

C. After the completion of steps A and B, the work of dismantling the temporary road and connecting the pedestrian bridge R is carried out.

The lane change method of the vehicle traveling from the west to the east is the same as the lane change method of the vehicle from the east to the west. The construction method of the hook-type rotary road traffic facility, which does not affect the traffic, includes the following steps:

A. First, expand the main roads at the intersection by 10 meters to 20 meters wide and 200 meters long for new roads. Then take some roads and start construction of the hook-type rotary overpass A or the hook-type rotary tunnel A. The construction period is 4 to 7 months;

B. After the hook-type rotary overpass A or the hook-type rotary overpass tunnel A is completed, the new roads with 10 to 20 meters on both sides of the secondary road and 200 meters long are temporary secondary roads. All vehicles on the secondary road pass through the hook-type revolving bridge A or the hook-type revolving tunnel A to complete the straight or turn; then close the middle part of the secondary trunk to carry the straight overpass B or the underground straight tunnel B and The construction of the part of the pedestrian bridge R is expected to last 4 to 7 months;

C. After the completion of steps A and B, remove the temporary road and connect the pedestrian bridge The work of R is expected to be 2 months. In the implementation, as shown in Figure 1, the driver who travels from south to north only needs to confirm whether it is a right turn or another driving direction before reaching the overpass, and then choose whether to go straight or turn, and the last bridge is completed. A lane change in the direction of travel is required. Before reaching the overpass, the driver who travels from east to west only needs to choose whether to go straight or turn. The last time the bridge completes the lane change to the direction of travel, and the other directions are analogous. In the case of a pedestrian bridge, the bridge can be constructed as long as the minimum width of a road reaches 50 meters (the distance between the building and the building) and the conditions of the two-way 10 lanes are met. Compared with the omnidirectional interchange technology currently used, it can save a lot of bridge infrastructure investment and occupy a small amount of land. If it is built in the old downtown area, it can reduce the total investment by more than 80%. The invention is fully capable of full underground construction. In the underground, additional non-motor vehicle underground special passages can be added.

What is described in the embodiments of the present invention is that the vehicle is traveling on the road to the right. If it is for the vehicle to travel on the road to the left, it is also true.
