Abstract
Description
Technical Field
[0001] The present application relates to the field of road engineering, and in particular to a novel elevated overpass. Background Art
[0002] Urban river-crossing bridges usually need to cross the river and the riverside roads on both sides. In order to communicate with the riverside roads on both sides, a grade separation needs to be set up. Grade separation refers to the intersection of roads and roads, or roads and railways at different elevations. Overpasses, tunnels, etc. are used to make the intersecting roads intersect on different planes, which is referred to as an interchange.
[0003] Traffic bridges that are usually equipped with flyovers are also called flyovers. Their main purpose is to ensure that traffic at intersections is not affected, and traffic jams caused by traffic lights are not disturbed. However, many flyover designs currently have the following problems: weak traffic functions, resulting in high energy consumption and difficulty in traffic for motor vehicles, such as figure-eight flyovers and some cloverleaf (AB) bridges. In contrast, the traffic of circular ramp flyovers will be improved, but when there is continuous heavy rainfall, a large amount of "guest water" enters the low point of the bridge area, which is not conducive to flood discharge. It is easy to accumulate water, block traffic, and even endanger lives, especially for urban river bridges. This situation is particularly obvious.
[0004] Therefore, for urban river bridges, how to ensure that they are conducive to flood discharge while ensuring good traffic functions is an important issue that needs to be solved urgently. Summary of the invention

[0009] In one embodiment, the upward motor vehicle circular ramp gradually increases in height from the connection with the third directional lane until it is flush with the height of the first directional lane; the downward motor vehicle circular ramp gradually decreases in height from the connection with the second directional lane until it is flush with the height of the third directional lane.
[0010] In one embodiment, the two motor vehicle directional ramps include an upward motor vehicle directional ramp and a downward motor vehicle directional ramp, wherein one end of the upward motor vehicle directional ramp is connected to the first direction lane and the other end is connected to the first extension road of the fourth direction lane, and one end of the downward motor vehicle directional ramp is connected to the second direction lane and the other end is connected to the second extension road of the fourth direction lane.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0033] First, some technical terms in the present application are explained to facilitate those skilled in the art to understand the present application.
[0034] Grade separation: referred to as interchange, refers to a traffic facility that uses overpasses or tunnels to allow intersecting roads to intersect each other on different planes.
[0035] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.
[0036] The embodiment of the present application provides a new type of elevated overpass.
[0037] In one embodiment, referring to Figure 1 , Figure 1 Schematic diagram of the plan view of the novel elevated overpass in the embodiment of the present application. Figure 1As shown, the novel elevated flyover includes: a main line bridge 1 and an intersecting road 2 intersecting at upper and lower levels, the intersection of the two is a grade separation 3, the main line bridge 1 crosses a river 4, and crosses the intersecting road 2, and the intersecting road 2 is located on one side of the river 4. In this embodiment, the flyover is an urban river-crossing bridge, the main line bridge 1 crosses the river 4, the intersecting road 2 is set on the ground on one side of the river 4, and has a certain distance from the river 4 (if the intersecting road 2 is set on the river bank, there is a water level warning line on the river bank, and the level of the intersecting road 2 is set higher than the level of the water level warning line of the river 4), the main line bridge 1 crosses the intersecting road 2, and the intersection of the two forms a grade separation 3, and the grade separation 3 separates the lanes on the main line bridge 1 from the lanes on the intersecting road 2, thereby avoiding the formation of intersection conflict points, ensuring traffic safety, and greatly improving the road's traffic capacity and transportation efficiency. It should be noted that, in this embodiment, the main line bridge 1 and the intersected road 2 are both two-way through lanes, wherein the two through lanes of the main line bridge 1 are used for going up the bridge to the opposite river bank, and the other for going down the bridge from the opposite river bank.
[0038] Preferably, the new elevated overpass also includes two motor vehicle circular ramps 5 and two motor vehicle directional ramps 6, the two motor vehicle circular ramps 5 and the two motor vehicle directional ramps 6 are symmetrical about the main line bridge 1, and the two motor vehicle circular ramps 5 are located on the side of the intersecting road 2 away from the river 4, one end of the motor vehicle circular ramp 5 is connected to the main line bridge 1, and the other end is connected to the intersecting road 2 at the grade separation 3; the two motor vehicle directional ramps 6 are located on the other side of the intersecting road 2, one end of the motor vehicle directional ramp 6 is connected to the main line bridge 1, and the other end is connected to the intersecting road 2.
[0039] In this embodiment, the main line bridge 1 and the intersecting road 2 are both two-way straight lanes. The novel elevated overpass is also provided with two motor vehicle circular ramps 5 and two motor vehicle directional ramps 6 to ensure the interconnection between the main line bridge 1 and the intersecting road 2. The two motor vehicle circular ramps 5 and the two motor vehicle directional ramps 6 are symmetrically arranged about the main line bridge 1, and the two motor vehicle circular ramps 5 are located on the side of the intersecting road 2 away from the river 4. One end of the motor vehicle circular ramp 5 is connected to the main line bridge 1, and the other end is connected to the intersecting road 2 at the grade separation 3. In this way, it is conducive for motor vehicles to smoothly go up the bridge along the motor vehicle circular ramp 5 from the lane on the side of the intersecting road 2 away from the river 4 (the intersecting road 2 is a two-way straight lane, and this lane is the lane on the side of the intersecting road 2 away from the river 4, and one of the driving directions) or it is conducive for motor vehicles to go down the bridge along the motor vehicle circular ramp 5 from the main line bridge 1 to the lane on the side of the intersecting road 2 away from the river 4, reducing traffic congestion caused by lane change, deceleration or parking of motor vehicles, ensuring smooth transition of motor vehicles in different directions, and improving the speed and efficiency of the overall traffic flow. In addition, by arranging the two motor vehicles on the side of the intersecting road 2 away from the river 4, when encountering continuous heavy rainfall, the water level of the river 4 rises rapidly, which can prevent a large amount of "guest water" from entering the low point of the bridge area, causing waterlogging and blocking traffic. By arranging the two motor vehicle directional ramps 6 on the other side of the intersecting road 2, one end of the motor vehicle directional ramp 6 is connected to the main line bridge 1, and the other end is connected to the intersecting road 2. In this way, it is beneficial for motor vehicles to smoothly go up the bridge along the motor vehicle circular ramp 5 from the lane on the other side of the intersecting road 2 (this lane is the lane of the other driving direction of the intersecting road 2), or it is beneficial for motor vehicles to go down the bridge from the main line bridge 1 to the lane on the other side of the intersecting road 2 along the motor vehicle circular ramp 5. At the same time, the directional ramp not only realizes the rapid turning and passing of motor vehicles, reduces congestion time, and improves traffic efficiency, but also uses less land.
[0040] Further, in one embodiment, referring to Figure 2 , Figure 2 For this application Figure 1 Schematic diagram of the motorway in the middle. Figure 2As shown, the mainline bridge 1 includes a plurality of first direction lanes 11 and a plurality of second direction lanes 12, the first direction lanes 11 and the second direction lanes 12 are opposite direction lanes, and the intersected road 2 includes a plurality of third direction lanes 21 and a plurality of fourth direction lanes 22, the third direction lanes 21 and the fourth direction lanes 22 are opposite direction lanes, and the third direction lane 21 is set away from the river 4. In this embodiment, the mainline bridge 1 and the intersected road 2 are both two-way straight lanes, wherein the mainline bridge 1 includes a plurality of first direction lanes 11 and a plurality of second direction lanes 12, and since the mainline bridge 1 crosses the river 4, the purpose is to connect the two banks of the river 4, so the two opposite direction lanes of the mainline bridge 1 are actually one for getting on the bridge from this bank to the other bank, and the other for getting off the bridge from the other bank to this bank. The intersected road 2 includes a plurality of third direction lanes 21 and a plurality of fourth direction lanes 22, and the two opposite direction lanes of the intersected road 2 are also to ensure that motor vehicles of different driving directions can get on or off the bridge normally, wherein the lane of the intersected road 2 away from the river 4 is marked as the third direction lane 21.
[0041] In actual application scenarios, the intersected road 2 and the main line bridge 1 intersect each other to form a grade separation 3, but it is not necessarily a cross-shaped horizontal and vertical intersection. The number of lanes of the first direction lanes 11 and the second direction lanes 12 can be 1, 2, 3 or 4, and the same is true for the third direction lanes 21 and the fourth direction lanes 22.
[0042] Further, in one embodiment, if Figure 2 As shown, the two motor vehicle circular ramps 5 include an upward motor vehicle circular ramp 51 and a downward motor vehicle circular ramp 52. One end of the upward motor vehicle circular ramp 51 is connected to the first direction lane 11, and the other end is connected to the third direction lane 21 at the grade separation intersection 3. The downward motor vehicle circular ramp 52 is connected to the second direction lane 12, and the other end is connected to the third direction lane 21 at the grade separation intersection 3. In this embodiment, the two motor vehicle circular ramps 5 include an upward motor vehicle circular ramp 51 and a downward motor vehicle circular ramp 52. By connecting one end of the upward motor vehicle ramp to the first direction lane 11 and the other end to the third directional lane 21 at the grade separation, the third directional lane 21 at the grade separation can be ascended along the upward motor vehicle ramp to the first direction lane 11, and cross the river 4 to the other bank through the first direction lane 11, thereby effectively improving the traffic efficiency; by connecting the downward motor vehicle circular ramp 52 to the second direction lane 12 and the other end to the third directional lane 21 at the grade separation 3, the motor vehicles in the second direction lane 12 can descend along the downward motor vehicle ramp to the third directional lane 21 at the grade separation 3, ensuring that the motor vehicles that have crossed the river 4 get off the bridge from the third directional lane 21 at the grade separation, thereby effectively improving the traffic efficiency.
[0043] Further, in one embodiment, if Figure 2 As shown, the height of the upward motor vehicle circular ramp 51 gradually increases from the connection with the third directional lane 21 until it is flush with the height of the first directional lane 11; the height of the downward motor vehicle circular ramp 52 gradually decreases from the connection with the second directional lane 12 until it is flush with the height of the third directional lane 21. In this embodiment, the shapes of the upward motor vehicle circular ramp 51 and the downward motor vehicle circular ramp 52 are both elliptical, wherein the upward motor vehicle circular ramp 51 gradually increases from the connection with the third directional lane 21 until it is flush with the height of the first directional lane 11, which is conducive to the motor vehicle slowly going up to the first directional lane 11 along the upward motor vehicle circular ramp 51, thereby achieving the purpose of going up the bridge; the height of the downward motor vehicle circular ramp 52 gradually decreases from the connection with the second directional lane 12 until it is flush with the height of the third directional lane 21, which is conducive to the motor vehicle slowly going down to the third directional lane 21 along the downward motor vehicle circular ramp 52, thereby achieving the purpose of going down the bridge.
[0044] Further, in one embodiment, if Figure 2 As shown, the two motor vehicle directional ramps 6 include an upward motor vehicle directional ramp 61 and a downward motor vehicle directional ramp 62. One end of the upward motor vehicle directional ramp 61 is connected to the first direction lane 11, and the other end is connected to the first extension road 221 of the fourth direction lane 22. One end of the downward motor vehicle directional ramp 62 is connected to the second direction lane 12, and the other end is connected to the second extension road 222 of the fourth direction lane 22. In this embodiment, the two motor vehicle directional ramps 6 include an upward motor vehicle directional ramp 61 and a downward motor vehicle directional ramp 62. Since the directional ramps directly enter or exit the road according to the turning direction, in order to avoid traffic congestion and accidents, it is necessary to respectively set a first extension road 221 and a second extension road 222 on the fourth direction lane 22. By connecting one end of the upward motor vehicle directional ramp 61 to the first direction lane 11 and the other end to the first extension road 221 of the fourth direction lane 22, and connecting one end of the downward motor vehicle directional ramp 62 to the second direction lane 12 and the other end to the second extension road 222 of the fourth direction lane 22, it is ensured that the driver maintains a good line of sight during the driving of the motor vehicle, reduces the driving blind spot, and thus improves driving safety.
[0045] Furthermore, in one embodiment, the upward motor vehicle directional ramp 61 and the downward motor vehicle directional ramp 62 are arranged in an eight-shaped manner on both sides of the main line bridge 1. In this embodiment, since there is a certain height difference between the main line bridge 1 and the intersecting road 2, the upward motor vehicle directional ramp 61 and the downward motor vehicle directional ramp 62 are arranged in an eight-shaped manner on both sides of the main line bridge 1, which is convenient for motor vehicles to climb the slope. At the same time, the upward motor vehicle directional ramp 61 and the downward motor vehicle directional ramp 62 are arranged on the side of the intersecting road 2 close to the river 4, which is also conducive to rapid drainage when encountering continuous heavy rainfall, preventing water accumulation from blocking traffic.
[0046] Further, in one embodiment, if Figure 2 As shown, the upward motor vehicle directional ramp 61 gradually increases in height from the connection with the fourth direction lane 22 until it is flush with the height of the first direction lane 11; the downward motor vehicle directional ramp 62 gradually decreases in height from the connection with the second direction lane 12 until it is flush with the height of the fourth direction lane 22. In this embodiment, the upward motor vehicle directional ramp 61 gradually increases in height from the connection with the fourth direction lane 22 until it is flush with the height of the first direction lane 11, which is conducive to the motor vehicle to slowly go up from the upward motor vehicle directional ramp 61 to the first direction lane 11 from the connection with the fourth direction lane 22, thereby achieving the purpose of going up the bridge; the downward motor vehicle directional ramp 62 gradually decreases in height from the connection with the second direction lane 12 until it is flush with the height of the fourth direction lane 22, which is conducive to the motor vehicle to slowly go down from the downward motor vehicle directional ramp 62 to the fourth direction lane 22 from the connection with the second direction lane 12 along the downward motor vehicle directional ramp 62, thereby achieving the purpose of going up the bridge.
[0047] Further, in one embodiment, reference Figure 3 , Figure 3 For this application Figure 1 Schematic diagram of the middle and slow lane. Figure 3 As shown, a sidewalk 7 is provided on each side of the main line bridge 1, and the flyover further includes: two non-motor vehicle circular ramps 8 symmetrically arranged with respect to the main line bridge 1, one end of the non-motor vehicle circular ramp 8 is connected to the adjacent sidewalk 7, and the other end is connected to the intersecting road 2 at the grade separation 3. In this embodiment, by providing a sidewalk 7 on each side of the main line bridge 1, and symmetrically arranging two non-motor vehicle circular ramps 8 with respect to the main line bridge 1, wherein one end of the non-motor vehicle circular ramp 8 is connected to the adjacent sidewalk 7, and the other end is connected to the intersecting road 2 at the grade separation 3, it can be ensured that pedestrians or non-motor vehicles (such as bicycles or battery vehicles) can go up or down the bridge through the non-motor vehicle circular ramps 8, and the arrangement of the sidewalk 7 can separate pedestrians and motor vehicles, thereby reducing the occurrence of traffic accidents.
[0048] Further, in one embodiment, if Figure 3 As shown, an elevator 9 is installed between the sidewalks 7 on each side of the main line bridge 1 and the crossed road 2 at the grade separation 3. In this embodiment, by installing the elevator 9 between the sidewalks 7 on each side of the main line bridge 1 and the crossed road 2 at the grade separation 3, it is convenient for pedestrians to quickly get on or off the bridge, saving the time of passing.
[0049] Furthermore, in one embodiment, a plurality of isolation piles are arranged at the connection position between the intersecting road 2 at the grade-separated intersection 3 and the motor vehicle roundabout ramp 5, and the plurality of isolation piles are arranged at equal intervals, and the outer wall fixed sleeves thereof are provided with elastic rubber rollers. In this embodiment, by arranging a plurality of isolation piles at the connection position between the intersecting road 2 at the grade-separated intersection 3 and the motor vehicle roundabout ramp 5, it is possible to effectively avoid the intersecting road 2 at the grade-separated intersection 3 and the motor vehicles on the motor vehicle roundabout ramp 5 from interfering with each other and causing traffic accidents. By arranging a plurality of isolation piles at equal intervals, and the outer wall fixed sleeves thereof are provided with elastic rubber rollers, it is possible not only to provide uniform and stable support, but also to play a role of buffering and protection, and to prevent the isolation piles from being damaged due to external impacts.
