Description

A vertical layered interchange structure

technical field

The utility model relates to the field of road reconstruction, in particular to a vertical layered interchange structure.

At present, the land for urban road construction is relatively tight, especially in the downtown area, the land for road construction is greatly restricted. At the same time, the renovation projects based on the existing facilities in the existing cities face more difficulties. Some renovation projects are even new projects outside the planned road network, but it is difficult to provide a large-scale headroom or ground demand in the city. . With the development of the city and the more and more heavy traffic operation, when the traffic volume of some roads reaches a certain scale, it is necessary to extract part of the traffic flow from the existing roads to improve the efficiency of traffic operation, and it can also alleviate the existing roads. level of congestion. The conventional treatment method is to add new bridges, including ramps to realize various steering functions, and at the same time, ground roads are arranged under the bridges to maintain the functions of the existing roads.

Reasonable diversion of traffic through bridges can relieve traffic pressure to a large extent, and can also avoid huge congestion caused by a single accident. In most cases, the traffic round-trip is realized on the same bridge, or the round-trip two roads are separated but located on the same height plane, and the total width of the road cross section is relatively wide. The wider cross-section increases the difficulty of expropriation and demolition, and at the same time, the distance between the bridge and the buildings on both sides is closer, which has a greater impact. Especially when the clearance under the bridge is not high, the wider bridge will cause a feeling of depression for the traffic and pedestrians under the bridge, such depression includes space, light and so on. Elevating the bridge will undoubtedly increase the project cost, and the scale of the bridge will also increase and increase the impact on the surrounding area. For the reconstruction of bridges along the existing roads, the round-trip traffic is located in the same height plane, which cannot well meet the needs of urban traffic reconstruction.

Detailed ways

Referring to FIGS. 1 and 2 , the present invention is a vertical layered interchange structure, comprising a lateral road 1 , a raised first ramp bridge 2 and a raised second ramp bridge 3 . For convenience of description and not representing its actual direction, the lateral road 1 is divided into an upper lane 11 and a lower lane 12 as shown in FIG. 2 . The on-vehicle lane 11 and the off-vehicle lane 12 do not represent the driving direction, but for the convenience of description, they are referred to as a series of lanes in the same direction on the same road. The first ramp bridge 2 and the second ramp bridge 3 are respectively raised overpass structures, both are located on the lateral road 1, and both are one-way lanes. The first ramp bridge 2 divides the off-road 12 , and forms a first entrance 21 and a first exit 22 on the off-road 12 . The second ramp bridge 3 divides the upper lane 11 , and forms a second entrance 31 and a second outlet 32 on the upper lane 11 . Both the first entrance 21 and the first exit 22 only occupy part of the lanes of the lower lane 12, the second entrance 31 and the second exit 32 only occupy part of the lanes of the upper lane 11, and the remaining unoccupied lanes continue to play their original roles. some effect. The plane projections of the first ramp bridge 2 and the second ramp bridge 3 at least partially overlap, and it can be that part of the bridge body of the first ramp bridge 2 is located vertically above the second ramp bridge 3, or it can be part of the bridge of the second ramp bridge 3 The body is located vertically above the first ramp bridge 2 .

As a preferred embodiment, the part of the first ramp bridge 2 between the first entrance 21 and the first exit 22 is the first bridge body, and the part of the second ramp bridge 3 between the second entrance 31 and the second exit 32 is the first bridge body. The second bridge body, the first bridge body is located vertically above the second bridge body, thereby forming a three-story interchange structure together with the lateral road 1 . The transverse road 1 is located on the bottommost floor, the second ramp bridge 3 is located on the middle level, and the first ramp bridge 2 is located on the topmost level. Above the first ramp bridge 2 , between the first ramp bridge 2 and the second ramp bridge 3 , and between the second ramp bridge 3 and the lateral road 1 below it all meet the clearance requirements for driving. Vehicles enter and exit the get-off lane 12 within the interchange structure from the lane not covered by the first entrance 21 and the first exit 22 on the get-off lane 12 outside the interchange structure. Vehicles enter and exit the pick-up lane 11 within the interchange structure from the lane on the pick-up lane 11 outside the interchange structure that is not covered by the second entrance 31 and the second exit 32 .

In this embodiment, the lateral road 1 is provided with a first longitudinal track 4 and a second longitudinal track 5 respectively, and both the first longitudinal track 4 and the second longitudinal track 5 are two-way lanes. The first longitudinal track 4 is located on the left side as shown in FIG. 2 , and the second longitudinal track 5 is located on the right side as shown in FIG. 2 . The definitions of the left and right sides are only for convenience of expression and description, and do not represent specific directions. The first longitudinal road 4 and the second longitudinal road 5 respectively intersect the transverse road 1 to form a first intersection and a second intersection, and the distance between the first intersection and the second intersection is relatively large. The section of the lateral road 1 between the first intersection and the second intersection has relatively large traffic pressure, and the lateral road 1 cannot be expanded outward, and the construction of the ordinary ramp bridge is greatly affected by the existing construction facilities. In this embodiment, the upper lanes 11 and the lower lanes 12 of the lateral road 1 both include two lanes, arranged in order from top to bottom. The first longitudinal lane 4 and the second longitudinal lane 5 each include four lanes, arranged in order from left to right.

The lateral road 1 is provided with a first ramp bridge 2 and a second ramp bridge 3 on the road section between the first intersection and the second intersection. Both the first ramp bridge 2 and the second ramp bridge 3 are raised overpass structures. The first ramp bridge 2 is used to relieve the traffic pressure on the off-road 12 , and the second ramp bridge 3 is used to relieve the traffic pressure on the on-road 11 . The first entrance 21 , the first exit 22 , the second entrance 31 and the second exit 32 are all located between the first intersection and the second intersection, and the first entrance 21 and the first exit 22 are all located at the edge of the lower lane 12 . On the second lane, both the second entrance 31 and the second exit 32 are located on the first lane of the upper carriageway 11 .

The extension direction of the first bridge body and the second bridge body is the same as that of the transverse road 1 , and the plane projections of part of the first bridge body and the second bridge body are located in the middle of the transverse road 1 . The slopes of the first ramp bridge 2 and the second ramp bridge 3 are substantially the same, but the height of the first ramp bridge 2 at the intersection with the second ramp bridge 3 in the plane projection is higher than that of the second ramp bridge 3, and the height is higher than that of the second ramp bridge 3. It is sufficient to provide the traffic clearance of the second ramp bridge 3 . Viewed from the plane projection of the first ramp bridge 2 , the first entrance 21 turns from the alighting lane 12 to the middle of the lateral road 1 to form a first bridge body, and then turns from the middle of the lateral road 1 back to the alighting lane 12 . Viewed from the plane projection of the second ramp bridge 3 , the second entrance 31 turns from the upper lane 11 to the middle of the lateral road 1 to form the first bridge body, and then turns from the middle of the lateral road 1 back to the upper lane 11 .

On the section of the lateral road 1 between the first intersection and the second intersection, the vehicles on the off-road 12 drive from the left to the right as shown in FIG. 2 . Vehicles in the get-off lane 12 enter the second lane of the get-off lane 12 , enter the first ramp bridge 2 through the first entrance 21 , and proceed to the first exit 22 along the first ramp bridge 2 . Vehicles in the alighting lane 12 enter the first lane of the alighting lane 12 and enter the section of the lateral road 1 located under the interchange structure. There are two lanes, and the first lane near the first exit 22 to the down lane 12 exits the interchange structure section. In the section of the lateral road 1 between the first intersection and the second intersection, vehicles on the roadway 11 drive from the right side to the left side as shown in FIG. 2 . Vehicles in the upper lane 11 enter the first lane of the upper lane 11 and enter the second ramp bridge 3 through the second entrance 31 , and proceed along the second ramp bridge 3 to the second exit 32 . The vehicle in the upper lane 11 enters the second lane of the upper lane 11 and enters the section of the lateral road 1 located under the interchange structure, and can choose to enter the first lane of the upper lane 11 after passing the second entrance 31. One lane, and the second lane, which is close to the second exit 32, goes to the upper carriageway 11 and exits the interchange structure section.

In this interchange structure, the first exit 22 or the second exit 32 is directed to the second intersection and the first intersection, respectively, and the distance between the first exit 22 and the second intersection and the distance between the first exit 22 and the second intersection and the distance between the second exit 32 and the second intersection should be appropriately increased. The distance to the first intersection. Because many times there are light controls or ramps at the intersection, the speed of the vehicle is relatively slow or there is a need to wait in line. However, when the vehicle exits the first exit 22 or the second exit 32, it is usually in a downhill state, which tends to make the vehicle speed faster. If the first exit 22 or the second exit 32 is close to the second intersection and the first intersection, traffic conflicts are likely to cause accidents, or vehicles queue up to the first ramp bridge 2 or the second ramp bridge 3 at the first On the slope at the exit 22 or the second exit 32, there will be a greater traffic hazard. In order to better relieve the traffic pressure on the lateral road 1 as soon as possible, the first entrance 21 and the second entrance 31 will be as close as possible to the second intersection and the first intersection, respectively, while satisfying the traffic regulations.

For a ramp bridge with a round-trip lane set on the same plane, the entrance and exit in the round-trip direction are always located at the same longitudinal position, which will inevitably lead to a contradiction in the arrangement of the entrance and exit. And the entrance and exit of the round-trip direction located in the same longitudinal direction will be compressed into the section of the lateral road 1 under the interchange structure, forming a traffic bottleneck. In the vertical layered interchange structure, a single round-trip ramp is divided into a first ramp bridge 2 and a second ramp bridge 3. The first ramp bridge 2 and the second ramp bridge 3 will be set as vertical as possible. The upper and lower layers are structured, but the first inlet 21 , the first outlet 22 , the second inlet 31 and the second outlet 32 are staggered from each other and do not have a necessary relationship of positions. In this embodiment, from left to right on the lateral road 1 are the first entrance 21 , the second exit 32 , the first exit 22 and the second entrance 31 , which satisfies the traffic requirements to a large extent. The first entrance 21 occupies the second lane of the lower lane 12 , in particular, the road can be appropriately expanded or the existing lane can be narrowed, and the transverse road 1 can be divided into two lanes of the upper lane 11 in the longitudinal direction of the first entrance 21 . The two lanes of the lane and the alighting lane 12 become two lanes of the upper lane 11 and three lanes of the falling lane 12 . At this time, the first entrance 21 occupies one lane of the lower lane 12 , and the remaining two lanes of the upper lane 11 and the two lanes of the lower lane 12 that are not occupied can be open to traffic normally. The same arrangement can be adopted at the first outlet 22 , the second inlet 31 , the second outlet 32 .

When the distance between the first intersection and the second intersection is relatively long, in order to improve the convenience of traffic and improve its traffic service function, several bypass ramps can be set up, and each bypass ramp is connected by the transverse road 1 to the first ramp bridge 2 or the second ramp bridge 3. Vehicles on the cross road 1 can enter the first ramp bridge 2 or the second ramp bridge 3 through the bypass ramp, or vehicles in the first ramp bridge 2 or the second ramp bridge 3 can return to the cross road 1 through the bypass ramp . This vertical layered interchange structure is farther away from the building floors on both sides. For sensitive road sections such as schools, hospitals, etc., completely enclosed sound insulation measures can be provided on both sides of the first ramp bridge 2 and the second ramp bridge 3 , such as concrete structure or steel structure sound insulation wall. At the same time, lighting fixtures, such as high pressure sodium lamps or new energy-saving light sources, may be provided at the bottom of the first ramp bridge 2 . Alternatively, anti-collision walls may be provided on both sides of the first ramp bridge 2 and the second ramp bridge 3, and lighting fixtures may be provided on the anti-collision walls. The lighting fixtures connected to the bottom of the first ramp bridge 2 or the anti-collision wall can be provided on the first ramp bridge 2 with better lighting for lighting.

When carrying out road reconstruction, design and plan the ramp bridge according to actual needs. During the reconstruction process, the construction access road, traffic relief and enclosure of the newly built ramp bridge will be implemented first, and the main structure and ancillary facilities of the ramp bridge will be constructed. After completion, the construction access road and enclosure of the newly built ramp bridge will be demolished. Surface roads are then repaired and open to traffic.

In the construction or renovation of urban roads, the river flow in the city is also a key factor to be considered. Especially in urban built-up areas, the advantage of arranging road alignment along the river is that it is relatively easy to expropriate and demolish. However, the ground road will cover a large area of the river, which is unfavorable for the maintenance of the river. The roads arranged along the river flow are in the form of bridges, but at present it is still in the form of bridges where the round-trip lanes are located on the same plane road, which still covers a large area of the river flow, which is difficult to meet the requirements of open channels. This vertical layered interchange structure can also solve the above problems very well, and the lower bridge does not need to meet the clearance requirements for traffic, but only needs to meet the height requirements for river flow management.

Of course, the design creation is not limited to the above-mentioned embodiments, and the combination of different features of the above-mentioned embodiments can also achieve good effects. Those skilled in the art can also make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present application.
