Problems solved by technology

That is to say, when you think of reaching the diagonally opposite side, you have to wait halfway, so the passage time is long and the efficiency is low.

Embodiment 1

[0029] Such as figure 1 , Figure 4 As shown, based on the structure of twisted overpasses in urban roads, including motor vehicle lanes and non-motor vehicle lanes, the motor vehicle lanes are divided into three layers, one of which is a twisted lane, the other two layers are straight lanes, and the first The first floor, the second floor and the third floor are staggered in space, the twisting lane is connected with the straight lane through the ramp 1 arranged on both sides, and the non-motorized lane 4 is arranged on both sides of the straight lane. It is more convenient and faster for pedestrians and non-motor vehicles to pass on the surface. Battery cars and bicycles do not need to go over the overpass to cross the tunnel. Traffic accidents caused by steep slopes and slippery roads in rainy weather are avoided, and potential safety hazards are reduced.

[0030] The twisted lane is divided into a straight lane and a reverse lane. The straight lane and the reverse lane ...

Embodiment 2

[0042] Such as figure 2 , image 3 As shown, the structure of embodiment 2 is basically the same as that of embodiment 1, the difference is that: the linear driveway includes a viaduct 7 on the upper floor and a surface driveway 2 arranged below the viaduct 7, the entrance and exit sides of the viaduct 7 Both are provided with turning motor vehicle lanes and non-motor vehicle lanes 4 in turn outwardly, and one end of the ramp 1 is connected to the straight section 5, and the other end is connected to the turning motor vehicle lane corresponding to this side, and the end of the twisting section 6 away from the straight section 5 is connected to the ground surface. Lane 2 connects. This scheme reduces the setting of the underpass tunnel 3, uses the viaduct 7 to replace the underpass tunnel 3, reduces the excavation cost of the underground tunnel during the construction process, and at the same time can stabilize the structure. The turning is completed by the lane set on the g...

Embodiment 3

[0049] Such as Figure 5 As shown, the structure of embodiment 3 is basically the same as that of embodiment 1, and the difference is that this scheme adopts a four-way twisted driveway, and a two-layer twisted driveway is set above the roadway on the ground surface to improve its traffic capacity. At the same time, the occupation of land is reduced, and the cost is cheaper.

[0050] For traffic in which pedestrians keep to the left in some countries, this scheme is still feasible. It is only necessary to mirror the route and the bridge body according to the driving direction of the flyover.

Abstract

The invention discloses a structure of a torsional-type flyover based on an urban road and use thereof. The torsional-type flyover comprises a motor vehicle way and a non-motor vehicle way, wherein the motor vehicle way comprises three layers, one layer is a torsional-type vehicle way and the other two layers are linear-type vehicle ways; the first layer, the second layer and the third layer are staggered in space; the torsional-type vehicle way is communicated with the linear-type vehicle way through ring roads arranged on both sides; and the non-motor vehicle way is arranged on both sides of the linear-type vehicle way. By the structure and use, the traffic problems of crossroads in cities can be effectively solved, separated traffic of the motor vehicles and non-motor vehicles is realized, driving in any direction at the passing time of motor vehicles is ensured, direction or road crossing is avoided, and the passing smoothness is ensured.

Description

technical field [0001] The invention relates to a structure based on a twisted overpass in urban roads and its application, and belongs to the field of overpass construction in urban traffic. Background technique [0002] With the advancement of science and technology and the development of industry, the traffic volume in cities has increased sharply, and the original mode of transportation can no longer meet the requirements; The development of the business has also led to the pressure of urban traffic, which has caused a lot of inconvenience for people to travel. Designers try to improve the pressure of major intersections through design. The current traffic system is mainly composed of expressways, trunk roads, branch roads, and branch roads. In order to alleviate traffic congestion, it is mainly through the establishment of interchange bridges, the addition of circular expressways, and the addition of ramps. These methods will occupy a large amount of land. For some larg...
