Problems solved by technology

[0004] Most overpasses need to build complex detour ramps on the plane and elevation, the construction cost is high, the cycle is long, and it takes up a lot of scarce urban land
In addition, in the central area of ​​the city, due to historical, geographical and even political reasons, it is impossible to build modern overpasses on a large scale

Embodiment 1

[0039] Embodiment 1: A level crossing using a straight Yuwei overpass

[0040] Figure 1-Figure 3 It is an example of applying Yuwei overpass at a level crossing with 8 lanes in east-west direction and 4 lanes in north-south direction.

[0041] figure 1 Shown fish tail overpass bridge, its bridge body two ends touch the ground, is supported by pillar 62 in the middle. In the middle of the bridge body is a passage for only one car to pass. On both sides of the passage are left guardrail 60 and right guardrail 61. One end of the two side fences is connected with left fishplate 56 and right fishplate 58 respectively.

[0042] Fishplate 56 and fishplate 58 form a bell mouth, and its large end width is the size of two lanes, and its small end width is equal to the middle part of the bridge body, which is the width of one lane.

[0043] The large end of the fish tail port can just pass the vehicles of the two inner lanes in the forward and reverse directions. Vehicles can enter t...

Embodiment 2

[0048] Embodiment 2: Apply the level crossing of the cross fishtail overpass

[0049] Figure 4-Figure 8 It is an example of applying Yuwei overpass at a level crossing with 6 lanes in east-west and north-south respectively.

[0050] Figure 4 In the shown Yuwei overpass, the west, east, north and south four entrances each have the same Yuwei opening, and each Yuwei opening has a revolving door, which are revolving door 64, revolving door 65, and revolving door 66 respectively. With the revolving door 67, four revolving doors need to be used in conjunction, so that the cross-shaped fishtail overpass can be brought into play different functions.

[0051] For specific application conditions, please refer to the accompanying drawings for explanations:

[0052] Figure 4 It is a schematic diagram of passing west to east and north through the cross-shaped Yuwei overpass; at this time, the revolving door 64 is left-handed; the revolving door 65 is right-handed; the revolving door ...

Embodiment 3

[0057] Embodiment 3: level crossing using the concave fishtail overpass

[0058] Figure 9-Figure 10 It is an application example of sunken fishtail overpass

[0059] Since fishtail overpasses are generally used to pass cars, if a bridge is built above a level crossing, the clearance height of the bridge must ensure that large vehicles can pass through, and the general height is about 4.5 meters. If a sunken fishtail overpass is used, due to the low height of the car, the excavation depth of about 2 meters is generally sufficient to ensure the passage of the car, and the sunken fishtail overpass has little impact on the city appearance, so it is also a fishtail overpass worth recommending.

[0060] Figure 9 It is the view of the concave Yuwei overpass. In the figure, the west, east, north, and south four entrances each have the same Yuwei entrance, and each Yuwei entrance has a revolving door. Therefore, there is a main bridge plate 68 in the middle of the crossing, and a ...

Abstract

The invention relates to traffic unblocking equipment, and in particular relates to a fishtail flyover for unblocking the urban traffic. Horn-shaped fishtail openings are arranged at entrances and exits of the flyover; rotating doors are mounted at the fishtail openings; due to the matched use of the multiple rotating doors, the traveling directions of vehicles can be controlled. The flyover is generally applied in the peak traffic hour and can guide part of the vehicles to the flyover and relieve the traffic pressure. The fishtail flyover is mainly applied to a level crossing intersection of a downtown of a big city and can be also mounted in small and medium-sized cities which do not have conditions for erecting regular flyovers so as to relieve the traffic jam and improve the road passing capacity.

Description

technical field [0001] The invention relates to equipment for unblocking traffic, in particular to a fishtail overpass for unblocking urban traffic. Background technique [0002] The full name of the overpass bridge is "three-dimensional intersection bridge". It is a modern land bridge built at an important traffic intersection in the city, with upper and lower layers, multi-directional driving, and no mutual interference. [0003] Overpass bridges span over existing lines. Divided into separate and interconnected. The separated type only ensures that the vehicles on the upper and lower lines can pass independently; while the interchange type overpass allows the vehicles on the upper and lower lines to pass through each other. [0004] Most of the overpasses need to build complex detour ramps on the plane and elevation, the construction cost is high, the period is long, and especially a lot of scarce urban land will be occupied. In addition, in the central area of ​​the c...
