Technical Field

The invention relates to the technical field of overpasses, in particular to an intercommunicated loop double-layer overpass.

Background

The overpass is called as a three-dimensional overpass, and is a modern bridge which is built at the junction of more than two crossed roads, is layered up and down and does not interfere with each other in multiple directions. Because the construction cost is higher, the construction is usually only carried out at the intersection between the expressway intercommunication and the urban main road or the expressway, and the main function is to ensure that vehicles in all directions can pass through quickly without being controlled by traffic lights at the intersection.

There are generally two solutions for existing road crossings: one is that the upper and lower layers of road are intersected without communicating with each other, the traffic speed is high, but the road can not be changed between the upper and lower layers; the other is that the road has various interchange at the vertical intersection of the upper and lower layers, such as cloverleaf type interchange, etc., these interchange generally have large floor space, many layers, the engineering quantity is large, the fabrication cost is high, most guarantee the trunk line to go straight unimpededly, the straight-going vehicle of other directions will meet with turning vehicle, have not solved the interchange problem well, a roundabout interchange has solved the problem such as being large of floor space, but the roundabout car is driven slowly, easy to form the car to be detained, and roundabout has four exits to cause the vehicle driving route to cross, very easy to happen the traffic accident, so we propose a interchange type loop double-layer interchange, in order to solve the above-mentioned problem.
