Multifunctional tunnel grade separation hub bridge

Abstract

The invention relates to a multifunctional tunnel grade separation hub bridge which comprises a tunnel, a road surface and a bridge deck. The bridge is characterized in that longitudinal straight lanes are arranged in the tunnel; transverse right turn lanes and longitudinal right turn lanes are arranged on the road surface, and arch bridges are arranged over the transverse right turn lanes and the longitudinal right turn lanes; longitudinal left turn lanes are also arranged on the road surface, and transverse straight lanes are arranged on the bridge deck; a viaduct turning bridge is also connected to the bridge deck, and transverse left turn lanes are arranged on the viaduct turning bridge; a pedestrian and non-motor vehicle right turn lane is arranged on the road surface; culverts are arranged below the arch bridges; and lanes are arranged between the culverts of the two arch bridges of each intersection to realize the straight going, the left turning and the turning around of non-motor vehicles and pedestrians in the longitudinal direction and traverse direction. The invention has the advantages that non-cross pass is realized, and the motor vehicles, the non-motor vehicles and the pedestrians can simultaneously pass through at an intersection; quick pass is realized; the pass efficiency is improved; and the problems of traffic congestion and traffic jam are thoroughly solved.

Description

technical field [0001] The invention belongs to a traffic facility, in particular to a multifunctional tunnel interchange hub bridge. Background technique [0002] With the development of our country's economy, there are more and more vehicles of all kinds, and the traffic jams in cities are becoming more and more serious, especially in large and medium-sized cities. The main cause of traffic jam is that traffic lights are set at the intersections, and the setting of traffic lights greatly reduces the traffic rate of the road. On the surface, the vertical and horizontal traffic at the intersections alternates, and the traffic rate is 50%. The actual traffic rate is less than 20% due to reasons such as vehicle deceleration, starting, turning left and pedestrian violations, which is only about 10% of the fast traffic rate. [0003] In order to solve the problem of traffic congestion, overpasses are set up at intersections. Existing overpass bridge has many kinds, as butterfl...
