Description

Technical Field

[0001] The invention belongs to the technical field of road traffic construction, and in particular relates to a cross interchange type overpass. Background Art

[0002] The current urban traffic congestion has seriously affected the development of social economy. Every level crossing distributed in the urban road network is the root cause of congestion. Its low traffic capacity restricts the traffic efficiency of the entire road network.

[0003] Traditional technology mainly solves the need for vehicles in different directions to travel together around a space at a crossroad, such as setting up multiple non-intersecting bridges in the space of a crossroad to solve the need for vehicles in multiple directions to travel together at a crossroad, but it will cause the bridge to be multi-layered, occupy too much space, cost too high, easy to get lost, long time to pass, and increase in vehicle fuel consumption. In the prior art, CN200949199Y_woven cross interchange type overpass discloses a scheme of setting up two layers of cross interchange overpass at the crossroad, that is, a cross interchange overpass is constructed by four one-way roads formed by bifurcation at the intersection of two roads, but its disclosed left turn lane needs to be merged from the right side of the main road, resulting in the central area surrounded by the four one-way roads of the cross interchange overpass not being utilized, and its left turn lane and U-turn lane are both located outside the central area of ​​the cross interchange overpass, making the occupied area of ​​the entire cross interchange overpass large. In addition, the left turn lane and the right turn lane are both merged from the right side of the main road, which will cause vehicle congestion. Therefore, it is urgent to develop a cross interchange overpass that occupies a small area, requires little investment, has strong traffic capacity, is environmentally friendly and energy-saving, so as to transform the existing intersections.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Please refer to Figures 1 to 6 , Figure 1 This is one of the structural schematic diagrams of a cross interchange bridge provided in a specific implementation manner of the present invention; Figure 2 for Figure 1 A schematic diagram of the location layout of the cross interchange bridge in the first two-way road and the second two-way road provided in; Figure 3 The second structural schematic diagram of a cross interchange bridge provided by a specific implementation method of the present invention; Figure 4 for Figure 3A schematic diagram of the location layout of the cross interchange bridge in the first two-way road and the second two-way road provided in; Figure 5 The third structural schematic diagram of a cross interchange bridge provided by a specific implementation method of the present invention; Figure 6 for Figure 5 The schematic diagram of the location layout of the cross interchange bridge in the first two-way road and the second two-way road provided in . Among them, the direction of the arrow represents the direction of travel of vehicles in the road.

[0050] The cross interchange provided by the embodiment of the present invention comprises a first direction road 1 and a second direction road 2 running in opposite directions formed by a partial bifurcation of a first two-way road 100, and a third direction road 3 and a fourth direction road 4 running in opposite directions formed by a partial bifurcation of a second two-way road 200. The first direction road 1 and the second direction road 2 are arranged crosswise with the third direction road 3 and the fourth direction road 4, that is, the first direction road 1 and the second direction road 2 are arranged perpendicularly to the third direction road 3 and the fourth direction road 4. Each of the first direction road 1, the second direction road 2, the third direction road 3 and the fourth direction road 4 includes an elevated bridge section, and each of the junctions of the first direction road 1 and the third direction road 3, the junctions of the fourth direction road 4 and the first direction road 1, the junctions of the second direction road 2 and the fourth direction road 4, and the junctions of the third direction road 3 and the second direction road 2 are arranged up and down in an alternating manner through the elevated bridge section and the ground layer section.

[0051] Each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 is located at the highest point of its viaduct section at its first junction or at its second junction along its driving direction, and each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 is provided with a left turn lane on the left side between its first junction and the second junction.

[0052] Specifically, the exit of the left-turn lane 32 of the third directional road 3 and the entrance of the left-turn lane 12 of the first directional road 1 are arranged in an up-down staggered manner and merge into the left side road of the first directional road 1. The exit of the left-turn lane 12 of the first directional road 1 and the entrance of the left-turn lane 42 of the fourth directional road 4 are arranged in an up-down staggered manner and merge into the left side road of the fourth directional road 4. The exit of the left-turn lane 42 of the fourth directional road 4 and the entrance of the left-turn lane 22 of the second directional road 2 are arranged in an up-down staggered manner and merge into the left side road of the second directional road 2. The exit of the left-turn lane 22 of the second directional road 2 and the entrance of the left-turn lane 32 of the third directional road 3 are arranged in an up-down staggered manner and merge into the left side road of the third directional road 3.

[0053] Since each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 is provided with a left-turn lane on the left side between the first junction and the second junction thereof, and the entrance and exit of each left-turn lane are arranged in an up-and-down staggered manner with the entrance and exit of another lane, the four left-turn lanes (12, 22, 32, 42) in the embodiment of the present invention are all located inside the central area surrounded by the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4, so that the central area can be effectively utilized, so that the cross interchange overpass provided by the embodiment of the present invention occupies a small area and requires little investment. In addition, the four left-turn lanes (12, 22, 32, 42) of the cross interchange provided by the embodiment of the present invention all merge from the left side of a road in a certain direction, rather than from the right side of a road in a certain direction. Vehicles merging from the left side can be staggered with vehicles merging from the right side, thereby avoiding the interweaving and crossing of traffic. The cross interchange provided by the embodiment of the present invention achieves reasonable diversion according to the different directions of vehicle travel, with left turns to the left and right turns to the right, so that vehicles can go their own way.

[0054] Therefore, the cross interchange provided by the embodiment of the present invention has the advantages of small occupied area, low investment, reasonable diversion and merging of vehicles, and smoother traffic.

[0055] At the same time, the cross-interchange overpass provided by the embodiment of the present invention can also make vehicles exit first and enter last, reduce the convergence and intersection of vehicles, and realize zero waiting, no intersection, and fast passing through the intersection for traffic in all directions, which greatly improves the traffic capacity of the urban road network, reduces congestion, reduces the time of vehicle driving on the road, and reduces the fuel consumption and emissions of vehicles. Since most vehicles are diverted to the bridge, the comfort and safety of non-motor vehicles and pedestrians passing through the intersection are greatly improved. Since only two overhead floors are set, the maximum number of floors of the overpass is reduced; in addition, the bridge can be produced in a modular factory, which reduces the dead weight and construction cost of the bridge, shortens the construction period, and effectively improves the applicability and feasibility of the bridge.

[0056] Two confluences are continuously arranged on the right side of the main road of each of the four one-way streets of the woven cross interchange disclosed in CN200949199Y, so that the width of the main road varies greatly. The narrowing of the lane in the driving direction affects the smooth passage of vehicles and makes it easy to get lost. In view of this, in the cross interchange provided by the embodiment of the present invention, the width of the main road of the elevated bridge section of each of the first direction road 1, the second direction road 2, the third direction road 3 and the fourth direction road 4 is made the same as the width of the main road of the non-elevated bridge section. In this way, vehicles can be prevented from being congested and going wrong due to the width and narrowness of the lane in the direction of passage, and some vehicles exiting at the right or left exit will not affect the smooth passage of the main road.

[0057] On the basis of the above embodiment, the first directional road 1 is provided with a right turn lane 31 on the right side before its first junction, which merges into the third directional road 3 from the right side; the second directional road 2 is provided with a right turn lane 21 on the right side before its first junction, which merges into the fourth directional road 4 from the right side; the third directional road 3 is provided with a right turn lane 31 on the right side before its first junction, which merges into the second directional road 2 from the right side; the fourth directional road 4 is provided with a right turn lane 41 on the right side before its first junction, which merges into the first directional road 1 from the right side; and the right turn lanes (11, 21, 31, 41) are arc-shaped lanes.

[0058] Preferably, each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 widens to the right a distance before its right-turn lane and a distance after the right-turn lane merging therein to facilitate vehicles to change lanes gradually.

[0059] like Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, each of the first direction road 1, the second direction road 2, the third direction road 3 and the fourth direction road 4 is provided with a U-turn lane (13, 23, 33, 43) after the second intersection, so that the cross interchange provided by the embodiment of the present invention can be formed into a Chinese knot-type interchange, which has a more beautiful appearance, and also allows vehicles that need to turn left but turn right by mistake or vehicles that need to turn right but turn left by mistake to have the opportunity to enter the correct road through such a U-turn lane.

[0060] like Figure 3 and Figure 4 In other embodiments, each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 is provided with a U-turn lane before its first junction, so that vehicles that need to U-turn can turn around earlier.

[0061] Preferably, each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 widens to the left a distance before its left turn lane, a distance after the left turn lane merging into it, a distance before its U-turn lane and a distance after the U-turn lane merging into it, so as to facilitate vehicles to change lanes gradually.

[0062] like Figure 1-Figure 4 As shown, in a specific embodiment, each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 is located at the highest point of its viaduct section at its first junction.

[0063] The first directional road 1 is located at the upper part of the third directional road 3 at its first junction, and the entrance of the left turn lane 12 of the first directional road 1 is located at the upper part of the exit of the left turn lane 32 of the third directional road 3. The fourth directional road 4 is located at the upper part of the first directional road 1 at its first junction, and the entrance of the left turn lane 42 of the fourth directional road 4 is located at the upper part of the exit of the left turn lane 12 of the first directional road 1. The second directional road 2 is located at the upper part of the fourth directional road 4 at its first junction, and the entrance of the left turn lane 22 of the second directional road 2 is located at the upper part of the exit of the left turn lane 42 of the fourth directional road 4. The third directional road 3 is located at the upper part of the second directional road 2 at its first junction, and the entrance of the left turn lane 32 of the third directional road 3 is located at the upper part of the exit of the left turn lane 22 of the second directional road 2.

[0064] The viaduct section of each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 includes a slope section, a horizontal section and a downhill section. The slope section of the viaduct section of each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 starts after its right turn lane, so that vehicles turning right do not need to go uphill again and end at its first junction. The downhill section of the viaduct section of each of the first directional road 1, the second directional road 2, the third directional road 3 and the fourth directional road 4 starts after its left turn lane and ends in front of the left turn lane merging into it, so that left-turning vehicles can merge smoothly. That is to say, the elevated bridge section of each of the first direction road 1, the second direction road 2, the third direction road 3 and the fourth direction road 4 has a straight section after reaching the highest point at the first intersection, and then starts to go downhill after passing through its left turn lane. In this way, the vertical height difference between each of the first direction road 1, the second direction road 2, the third direction road 3 and the fourth direction road 4 and the other direction road at the first intersection is maximized, which is also convenient for vehicle drivers to react and observe the road after going uphill to the straight section.

[0065] The left-turn lane 12 of the first-direction road 1 includes a horizontal road surface close to the highest height of the first-direction road 1, a downward gently sloping road surface, and a horizontal road surface close to the lowest height of the fourth-direction road 4. The downward gently sloping road surface of the left-turn lane 12 of the first-direction road 1 starts at a point a where the upper and lower projections of the left-turn lane 12 of the first-direction road 1 and the left-turn lane 32 of the third-direction road 3 overlap, until it connects with the fourth-direction road 4 through the horizontal road surface.

[0066] The left-turn lane 42 of the fourth-direction road 4 includes a horizontal road surface close to the highest height of the fourth-direction road 4, a downward gently sloping road surface, and a horizontal road surface close to the lowest height of the second-direction road 2. The downward gently sloping road surface of the left-turn lane 42 of the fourth-direction road 4 starts at the point d where the upper and lower projections of the left-turn lane 42 of the fourth-direction road 4 and the left-turn lane 12 of the first-direction road 1 overlap, until it connects with the second-direction road 2 through the horizontal road surface.

[0067] The left-turn lane 22 of the second-direction road 2 includes a horizontal road surface close to the highest height of the second-direction road 2, a downward gently sloping road surface, and a horizontal road surface close to the lowest height of the third-direction road 3. The downward gently sloping road surface of the left-turn lane 22 of the second-direction road 2 starts at the point b where the upper and lower projections of the left-turn lane 22 of the second-direction road 2 and the left-turn lane 42 of the fourth-direction road 4 overlap, until it connects with the third-direction road 3 through the horizontal road surface.
