Problems solved by technology

[0007] The disadvantage of the directional ramp is that the ramps in each direction cross each other, which increases the level of the interchange, increases the area of ​​the bridge, and makes the bridge structure have the characteristics of "bending, slope, and oblique", which increases the difficulty of construction and increases the cost of the project.
Use the inner circular ramp to guide the vehicle to turn right 270° to achieve a left turn, and use the outer direct ramp to make a right turn; based on the above characteristics, only one overpass bridge needs to be built, and all turning vehicles have dedicated ramps, without plane intersections and conflict points. Compared with the interchange, the traffic capacity is larger, the vehicle speed is higher, and the driving is safe, but the area is larger, and the detour distance of the left-turning vehicle is long.

Embodiment 1

[0038] Embodiment 1: the basic bridge type of a single-lane two-way overpass.

[0039] Figure 1-Figure 4The characteristics of the basic bridge type are introduced through a four-handle single-lane two-way overpass:

[0040] figure 1 It is the basic structural diagram of the bridge body: four bridge handles 1 are evenly arranged around the top plate 2 of the dragon claw, the top of the bridge handles is connected to the top plate, and the pillar 3 is directly below the top plate. The width of each bridge handle can only allow one vehicle to pass through, and the vehicles on the bridge and the vehicles on the lower bridge pass alternately on the same bridge handle.

[0041] figure 2 It is a case where a four-handle single-lane two-way overpass is installed at a plane intersection: the four bridge handles are respectively installed in the four "vehicle evacuation areas" 4-1, 4-2, and 4 in the north, west, south, and east of the intersection. -3 and 4-4.

Embodiment 2

[0050] Embodiment 2: Embodiment of a single-lane two-way overpass using a rotary top plate drainage door

[0051] Figure 5 It is a single-lane two-way overpass using a rotary top plate diversion gate, which is a special left-turn bridge. Its bridge body is installed on the intersection of plane intersection; Except the rotary top plate draining door 5 on the top plate, the lower end of each bridge handle is also equipped with upper bridge left-turn vehicle control gate and lower bridge vehicle control gate.

[0052] The lower end of the bridge handle is facing the "waiting area for left-turn vehicles on the bridge", which is set up by occupying the inner lane of the "vehicle evacuation area". The area surrounded by barrier 9 is exactly, and its exit is equipped with upper bridge left-turn vehicle control gate 10-1.

[0053] Figure 5 Shown is a left turn west to north and turn east to south Simultaneously in the situation of passing on the bridge; at the lower end of t...

Embodiment 3

[0055] Embodiment 3: Embodiment of a one-lane two-way overpass using a plug-in top plate drainage door

[0056] The revolving door 5 of last example single-lane two-way overpass bridge, its revolving door axle is contained in the center of top plate, therefore can not pass through vehicle. The situation at the intersection is more changeable. Sometimes when the straight-going pressure in a certain direction is too high, it is necessary to divert some of the straight-going vehicles through the overpass. Therefore, this example presents a straight-going left-turn dual-purpose bridge. The difference between the two lies in the top plate. Replaced with a plug-in top plate drainage door.

[0057] Figure 7 It is a single-lane two-way overpass using plug-in top plate drainage doors. Four plug-in top plate drainage doors are installed on the top plate. Door. The picture shows a left turn west to north and turn east to south Simultaneously in the situation of passing on the bri...

Abstract

A single-lane and double-direction overpass and a crossing jam dredging system using the same are a technical means for improving the crossing passing efficiency by using a traffic dredging device to divert vehicles turning left at a plane intersection. The single-lane and double-direction overpass is a light and multifunctional overpass, the vehicles turning left on all roads of the plane intersection are commanded to alternately pass by using the unique alternate passing mode and using guide devices like top tray drainage doors on the bridge, most of the vehicles turning left are diverted from the bridge, and the aim of reducing the ground traffic pressure is achieved. The overpass is suitable for urban plane intersections without built large overpasses, can be used for rapid passageways where non-communicated overpasses have been built as well, and is used for relieving traffic jams under the bridge.

Description

technical field [0001] The invention relates to an urban traffic system, which is a single-lane miniature overpass capable of bidirectional conduction, and also includes an intersection dredging system using the overpass. Background technique [0002] Overpasses are an important part of modern urban traffic systems, but the disadvantages of overpasses are that they occupy a large area and require high investment. Because of this feature, overpasses are only used at intersections that are particularly busy or under heavy traffic pressure. [0003] Interchanges are also an important part of the urban road network system and a key factor affecting network accessibility. In the interchange planning and design, the choice of the form of the left-turn ramp determines the form of the interchange. According to the predicted traffic volume and service level of the ramp, directional ramps, semi-directional ramps, and circular ramps should be selected in sequence. Compatible with the ...
