Abstract
The invention relates to a junction single interchange structure. The junction single interchange structure comprises a first direction road, a second direction road, a third direction road, a fork-type communication curve and a one-way overpass. The one-way overpass is located above the third direction road. The fork-type communication curve is divided into a first left turning curve and a direct connecting track, and a vehicle gathering end is arranged at the right end of the fork-type communication curve. The first left turning curve communicates with a down channel of the third direction road. The direct connecting track is divided into two paths at the intersection. One path of the direct connecting track communicates with an up channel of the first direction road, and the other path of the direct connecting track communicates with the left end of the one-way overpass. A down channel of the first direction road is divided into two paths. One path communicates with the down channel of the third direction road through a first right turning curve, and the other path communicates with the left end of the one-way overpass. An up channel of the third direction road is divided into two paths. One path is a second right turning curve, and the other path is a second left turning curve. The junction single interchange structure has the characteristics of being simple in structure, easy to build, low in construction cost, small in floor space and capable of arranging floor routes at will.
Description
technical field [0001] The invention belongs to the technical field of road traffic, and in particular relates to a single interchange structure at a Sanchakou. Background technique [0002] When a vehicle passes through an urban highway traffic fork, its straight-going route and left-turning route will interfere with each other and affect each other. At present, on-site personnel command or lighting control are mostly used to maintain traffic disorder; some separate overpasses are also used, but only the vehicles on the bridge can pass smoothly, and the other directions still need to be released in turn, which cannot give full play to the existing urban areas. The function of transportation facilities. To realize the intercommunication of routes in all directions at the three-way intersection of highway traffic, it is necessary to build at least three layers of overpasses to realize. Contents of the invention [0003] The object of the present invention is to propose a ...
