Problems solved by technology

However, the existing overpass bridges are generally composed of multiple ramps, multi-layer overpass bridges and other structures. Not only the space height is large, the floor area is large, the space above the sidewalk of the overpass bridge has not been effectively utilized, and the adjacent overpass bridges are difficult to connect , it is difficult to realize a three-dimensional traffic network, which makes the ability to alleviate traffic jams very limited
Therefore, the existing overpasses are still difficult to meet the needs of the rapid development of society

Embodiment 1

[0039] Such as figure 1 As shown, taking an overpass arranged at a T-shaped intersection as an example, then correspondingly, the overall structure of the curved non-ramp overpass described in the present invention is also similar to a T-shaped overpass. The curved non-ramp overpass mainly includes a trunk road 1, a secondary trunk road located on one side of the trunk road, and a curved lane surrounding the trunk road 1 connected with the secondary trunk road. Among them, the trunk road 1, the secondary trunk road and the curved lane are all erected above the ground by supporting columns, and the curved lane is on the same level as a whole, while the two ends of the trunk road 1 and the secondary trunk road are slope sections 8 respectively, and the middle part is at the same level as the curved lane. on flat surface.

[0040] In this embodiment, the curved lane can be erected above the ground through support columns, or can be set below the ground. For the convenience of d...

Embodiment 2

[0048] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the curved non-ramp overpass described in the present invention is arranged at a crossroad, and correspondingly its overall structure is also similar to a cross, that is, the main road 1 and the secondary arterial road form a cross structure. In this case, the curved lane is axisymmetric with the main road 1 as the axis of symmetry, and there is no straight section, while other structures such as the turning section and the U-turn section are set the same as in Embodiment 1.

[0049] The working process of this embodiment is as follows:

[0050] First, the straight-going mode of the vehicles on the main road 1 remains unchanged, just follow their normal routes. The U-turn process of the trunk road 1 is as follows: After the vehicle passes the intersection of the trunk road 1 and the secondary trunk road, it enters the turning section 3, continues to go through the U-turn sectio...

Embodiment 3

[0054] Such as Figure 6 As shown, this embodiment takes figure 2 The structure shown is based on the design. The difference between the two is that in this embodiment, a main road and an auxiliary road formed by supporting columns are added on the outside of the curved lane. The shape of the trunk road and auxiliary road is the same as that of the curved lane, and they are on the same plane, that is, the trunk road and auxiliary road include the steering section 6 and the turning section 5 of the auxiliary road. Among them, the turning section 6 of the auxiliary road is arranged on the outside of the turning section 3 and merges with the turning section 3, while the U-turn section 5 of the auxiliary road is located above the slope section 8 of the secondary main road, and its two ends are connected to the adjacent auxiliary road turning section respectively. paragraph 6. The function of the main road auxiliary road is that when the auxiliary road turning section 6 of the a...

Abstract

The invention discloses a curve-type ramp-free overpass, belonging the technical field of public traffic and mainly solving the problems of high spatial height and wide occupation area of the overpass in the prior art. The curve-type ramp-free overpass comprises an arterial road and a secondary trunk road which are mutually crossed and is provided with a curve lane surrounding the arterial road with the secondary trunk road; and the curve lane is communicated with the arterial road. In the curve-type ramp-free overpass provided by the invention, through ingenious design and by utilizing the curve lane, the sheering and turning of the vehicles can be realized on the same layer on the ground, thus not only canceling the ramp, greatly reducing the spatial height and width and greatly simplifying the overall structure of the overpass but also realizing the free traveling of the vehicles at any direction; and after a three-dimensional traffic network is constructed, the traffic capacity can be effectively expanded, thus relieving the phenomenon of traffic jam.

Description

technical field [0001] The invention relates to an overpass bridge, in particular to a curved non-ramp overpass bridge. Background technique [0002] In today's society, motor vehicles have become one of the indispensable means of transportation in people's life and work, and with the rapid development of the economy, the number of motor vehicles will increase rapidly. The increase of motor vehicles will inevitably bring great pressure to urban traffic. [0003] In order to alleviate urban traffic congestion and improve traffic capacity, overpass bridges are often used to solve the vehicle traffic problem at intersections in cities. However, the existing overpass bridges are generally composed of multiple ramps, multi-layer overpass bridges and other structures. Not only the space height is large, the floor area is large, the space above the sidewalk of the overpass bridge has not been effectively utilized, and the adjacent overpass bridges are difficult to connect , it is...
