Description

An urban crossroad overpass

technical field

The utility model relates to an urban crossroad overpass, which belongs to the technical field of urban bridges.

Background technique

With the development of the automobile industry, there are more and more vehicles of all kinds, especially the increase of private cars in cities, which has caused tremendous pressure on urban traffic. loss. In order to alleviate the traffic pressure and thoroughly solve the problem of the difficulty of traveling due to the many people in the car, people have set up many traffic lights at city crossings, and often also have small overpasses. Most of the small overpass bridges built are to divert pedestrians, and pedestrians can reach the desired direction road section through the overpass bridge, avoiding the danger of crossing the road. Although the setting of traffic lights reduces the occurrence of traffic accidents, motor vehicles and non-motor vehicles that go straight or turn left often have to wait for traffic signals to run, which greatly reduces the speed of vehicles and reduces the utilization rate of urban roads; Traveling among motor vehicles often causes traffic jams. Therefore, it is an urgent problem to be solved to set up a kind of overpass bridge in which people and vehicles diverge and the vehicles traveling in each direction do not interfere with each other at urban crossroads.

Contents of the invention

The purpose of the utility model is to provide an urban crossroad overpass with simple structure, less land occupation and low construction cost to solve the problem of poor vehicle traffic at urban crossroads.

The technical scheme of the utility model is:

An urban crossroad overpass, which is composed of an approach bridge, a U-turn turntable, a straight left-turn turntable, and a right-turn ramp, is characterized in that: the center of the ground of the intersection is provided with a U-turn turntable through the ring-shaped inner column, and the motorway passes through the approach bridge and The U-turn turntable is connected, and the outside of the U-turn turntable is provided with a straight left-turn turntable through the ring-shaped outer column frame, and a non-motor vehicle roundabout is set on the ground between the inner column and the outer column; between the U-turn turntable and the straight left-turn turntable The approach bridge is connected by a right-turn ramp, the straight left-turn turntable is connected with the right-turn ramp by the uplink, and the straight left-turn turntable is connected with the motor vehicle lane by the downlink.

A pedestrian crossing passage is arranged under the ground at the junction between the approach bridge and the motorway.

The beneficial effects of the utility model are:

The overpass at the city crossroads has a simple structure and occupies less land. Through the U-turn turntable, right turn ramp and straight left turn turntable, the purpose of U-turn, straight left turn and right turn can be realized respectively. Non-motor vehicles and pedestrians pass through non-motor vehicle roundabouts respectively and pedestrian crossing passages to achieve unimpeded passage; improve the utilization rate of the road, save the time of waiting for traffic signals, increase the speed and flow of vehicles, and reduce the probability of traffic accidents.

Detailed ways:

This urban crossroad overpass is made up of approach bridge 1, U-turn turntable 2, straight-forward left-turn turntable 3, right-turn ramp 4, and the center of the ground of the crossroads is provided with U-turn turntable 2 by ring-shaped inner layer column 5, and motorway 6 passes approach bridge 1 Connected with the U-turn turntable 2, a pedestrian crossing passage 13 is provided below the ground at the junction of the approach bridge 1 and the motorway 6.

The outside of the U-turn turntable 2 is provided with a straight left-turn turntable 3 through an outer layer column 7 provided in a ring, and a non-motor vehicle roundabout 8 is arranged on the ground between the inner layer column 5 and the outer layer column 7; The motorway 9 is connected. The approach bridge 1 between the U-turn turntable 2 and the straight-going left-turn turntable 3 is connected by a right-turn ramp 4, the straight-going left-turn turntable 3 and the right-turn ramp 4 are connected by an uplink lane 11, and the straight-going left-turn turntable 3 passes through the motorway. Downlink lane 12 connects.

This urban crossroad overpass can respectively realize the purpose of motor vehicle turning around, going straight and turning left and turning right through U-turn turntable 2, right-turn ramp 4 and straight-going left-turn turntable 3, and non-motor vehicles and pedestrians pass non-motor vehicle roundabout 8 and Pedestrian crossing channel 13 realizes unimpeded passage; Taking the automobile 14 traveling from south to north as an example: enter the U-turn turntable 2 through the approach bridge 1 to realize the purpose of U-turn driving, and enter the right-turn ramp 4 through the approach bridge 1 to turn right. Enter the right-turn ramp 4 from the approach bridge 1, enter the straight left-turn turntable 3 through the up lane 11, and then go straight or turn left through the down lane 12, so that you can safely and smoothly reach the road in any direction. Equally, the non-motor vehicle enters the non-motor vehicle roundabout 8 along the non-motor vehicle lane 9, and travels around the non-motor vehicle roundabout 8 in a counterclockwise direction to arrive at the non-motor vehicle lane 9 in the direction of the destination. Pedestrians can turn right along the sidewalk 10, and only need to cross two pedestrian crossing passages 13 at most to reach the road in any direction.

The urban crossroad overpass has a simple structure and occupies less land, which can completely divert motor vehicles, non-motor vehicles and pedestrians, improve the utilization rate of the road, and reduce the probability of traffic accidents. It is especially suitable for the construction and use of the bustling intersection in the city.
