Embodiment Construction

[0011] As shown in Figure 1, set a straight double vehicle that is gradually higher than the ground at the crossroads in the X direction. It is connected to L6 and L8 on the y side. Note that the vertical distance between the main bridge facing L1 and L2 and the bridge deck L3 and L4 should be greater than or equal to 4m to facilitate the passage of vehicles in the direction of the main bridge L1 and L2. In order to prevent pedestrians, bicycles intersect with motor vehicles to set up pedestrian bicycle bridge c, c is a horizontal bridge connected to main bridge L1 and L2 before and after the intersection, it protrudes outside bridge L1, L2, so that pedestrians, The bicycle goes around and goes straight. Any vehicle can even go its own way to achieve the purpose of going straight and turning left like this, and the turning right vehicle can pass through the attached road L10 located at the main bridge L1, L2 both sides, and L14 directly travels right from the road surface.

Abstract

The invention relates to a subway-typed cloverleaf junction which is characterized in that the cloverleaf junction consists of direct two-lane main bridges (L1, L2) which are arranged on a crossing in the X-direction, and left-turning bridges (L3, L4) which are connected with the main bridges and finally turn to the external direction; concave roads (L7, L11) are arranged in the Y' direction of the crossing and turns left through a subway (11); all right-lane vehicles directly turn right on the ground surface through the auxiliary road. The subway-typed cloverleaf junction has the advantages of cancelling green lights, and leading various vehicles and passerby to move in their own ways..

Description

Technical field: [0001] The invention relates to a traffic facility, in particular to a tunnel type overpass. Background technique: [0002] Traditional overpasses need to use two-story or three-story structures and can be completed with the help of "traffic lights", and the flow of people and vehicles in all directions is connected. Therefore, it has the disadvantages of complex structure, high cost, and large floor space that affects traffic. Extensive searches have been carried out for the above problems, but no technical solutions related to the present invention have been found. Invention content: [0003] Purpose of the present invention is exactly the complex result that traditional overpass bridge exists, the shortcoming that cost is high designs a kind of brand-new overpass bridge of structure. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A kind of tunnel type overpass bridge, the same a...
