Three-dimensional transportation system for urban main road

Abstract

The invention relates to a three-dimensional transportation system for an urban main road, which solves the problem that the existing traffic mode can not adapt to road traffic flow pressure caused by increasing quantity of automobiles. The three-dimensional transportation system for the urban main road comprises a main line and branches, wherein the main line comprises an elevated road and a ground layer; a subway tunnel is arranged at the lower part of the ground layer; upright columns are arranged on the elevated road; the upright column in the center of the elevated road is deep into the lower surface of the subway tunnel and connected with a tunnel upper surface and a tunnel lower surface; the upright columns on the two sides of the elevated road are connected integrally with the side walls of the subway tunnel; a left tunnel and a right tunnel are arranged on the two sides of the subway tunnel; at a large-scale intersection, the left tunnel and the right tunnel are connected with the branches on the road by virtue of an underground flyover; the left tunnel and the right tunnel are connected by virtue of a left turn-in ramp and a right turn-out ramp arranged on the main line; and the branches are connected with the left tunnel and the right tunnel by virtue of right turn-in ramps and right turn-out ramps arranged on the branches. The three-dimensional transportation system is scientific in design; and because of an integral design of the upright columns of the elevated road and the walls of the tunnels, the pile foundation of the upright columns is not too deep so as to avoid easily destroying water channels on the underground deepest parts; and therefore, the traffic pressure on the road is effectively relieved.

Description

technical field [0001] The invention belongs to the field of urban road architectural design, in particular to a three-dimensional transport system for urban arterial roads. Background technique [0002] With the improvement of people's living standards, automobiles have become more and more important means of transportation. However, the increasing number of automobiles has brought serious congestion problems to urban traffic. The current traffic system is mainly composed of arterial roads and branch roads. In order to alleviate traffic congestion, it is mainly through the establishment of elevated roads, interchange bridges, the addition of circular expressways, and the addition of ramps. With the development of car familyization, only the improvement made on the existing traffic mode cannot meet the traffic problems such as the ground traffic pressure caused by the increasing number of cars. [0003] The urban elevated road is an overhead road built above the road with d...
