Winding across method of communicated crossroads

Abstract

The invention relates to a rounding-spanning method for a rounding-spanning interchange bridge. The method is relied on that the whole bridge has only one layer or a half of layer and the rest of vehicle trestles passing crossings belong to curve-shaped trestles constructed according to a circling method except two straight vehicle trestles of trunk road. The rounding-spanning method is that the trestles spanning crossings are needed to be rounded to the outside of the beginning of the spanned trestles to form the curve-shaped trestles so as to span crossings including T-shaped crossings, crossings and interlaced-road crossings rounding interchange bridges; wherein, the trunk road straight trestle A1 of the trunk road A has the height of one layer or a half of layer, and the trunk road A,sub-trunk road B and curve trestles interlaced and connected between sub-trunk roads all has the height of one layer or a half of layer, and a sideway ground under the trestles is lower than the ground of neighboring roads, and right-turning lane is directly turned to the right from ground. The interchange bridge can be constructed on the upper part of the original roads and occupies no additional areas with small occupy area, small construction work and low construction cost.

Description

technical field [0001] The invention relates to an overpass at an intersection, belonging to the technical field of traffic facility design. Background technique [0002] With the increase of the population and the increase of the number of cars, the traffic is becoming more and more congested, even jammed. This kind of congestion and jam mainly occurs at intersections, resulting in waste of time and frequent accidents, bringing new troubles to people. In order to solve this problem, overpass bridges are set up at intersections. However, these overpass bridges either occupy a large area, have many layers, a large amount of engineering, and high cost, which will bring huge damage to the urban landscape. Unable to implement. Either it can only ensure that the straight line of the main line is unimpeded, and the straight line in other directions merges with the turning, which does not fundamentally solve the traffic jam phenomenon at the intersection, and even often leads to c...

[0002] With the increase of population and the increase of the number of cars, the traffic is becoming more and more congested, even jammed. This kind of congestion and jam mainly occurs at intersections, resulting in waste of time and frequent accidents, bringing new troubles to people. In order to solve this problem, overpass bridges are set up at intersections. However, these overpass bridges either occupy a large area, have many layers, a large amount of engineering, and high cost, which will bring huge damage to the urban landscape. It is difficult or impossible to implement at urban intersections. unable to implement

Either it can only ensure that the straight line of the main line is not blocked, and the straight line and the turning intersection of other directions do not fundamentally solve the traffic jam at the intersection, and even often lead to collision accidents
