Two-deck full-directional direct-intercommunity overpass

Abstract

The invention discloses double-layer full-orientation and direct-interconnection overpass, the overpass is made up of bridge approach, deciliter tilt hole, cross bridge and inner arc curved road, the deciliter tilt hole and curved road are double-layer structure with upper and subjacent layer, each bridge approach is a mutual double bridge which contain a long and a short bridge, which two are connected to the outer end of upper and subjacent layer of the hole, the two sides of each layer in deciliter tilt holes are connected through curved road bridge, the centre part of the each hole is connected to cross bridge, the cross bridge are straight bridges which are orthogonal, the cross bridge is bidirectional one-way bridge, the two ends of it are connected with the upper and subjacent layer of the hole. The overpass can realize full-orientation and direct-interconnection with small area and cost.

Description

Technical field [0001] The invention relates to a highway overpass, in particular to a double-layer full-directional direct intercommunication overpass. Background technique [0002] The simplest overpass is a cross-orthogonal bridge, that is, an overpass or a tunnel bridge is opened on a straight road or through an orthogonal bridge hole. This kind of orthogonal bridge cannot solve the problem of steering. Then there was a ring overpass, that is, the straight and turning of all roads are realized on a ring bridge above the ground. Therefore, this kind of ring-type overpass has the problem of vehicle interactive driving. If the traffic volume is large, it will be blocked. At present, a kind of "clover leaf" type overpass is mostly used. This kind of overpass is equipped with four cloverleaf-shaped curve bridges and four arc-shaped curve bridges on the outside of the cloverleaf curve bridge in the four sections of the cross orthogonal bridge to realize left and right turning vehic...

AI Technical Summary

Problems solved by technology

However, this all-directional direct interchange type overpass must be built into a four-story structure to meet the above-mentioned traffic requirements, which makes the overpass have many layers, high layers, long approach bridges, and a wide area, and the high cost of building bridges

At present, there are only a few buildings in a very small number of developed countries in the world, so they are not of universal significance at all.
