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.

Embodiment Construction

[0011] As shown in Figs. 1 and 2, the double-layer full-directional direct inter-communication overpass of the present invention includes four approach bridges 1, four openings and shed tunnels 2, a cross orthogonal bridge 3, and eight inner-curved curve bridges 4. The layered shed 2 and the curved bridge 4 are both upper and lower double-layer structures. The four approach bridges 1 respectively lead to the four sections of the crossroads. Each approach bridge is divided into long and short approach bridges 1a and 1b with a single line of going and going, and the two are connected to a splitting shed 2. Among them, the long approach bridge 1a is connected with the outer end of the upper layer of the opening and closing shed 2 and the short approach bridge 1b is connected with the outer end of the lower layer of the opening and closing shed 2. The width of the opening and closing shed 2 is the same as the total width of the approach bridge 1. The inner ends of the upper and lower ...

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...
