Module type left and right turning overpass

Abstract

The invention provides a module type left and right turning overpass. The overpass consists of four basic modules, namely, a motor vehicle direct movement bridge, a left turning bridge, a right turning bridge and a support beam, wherein the motor vehicle direct movement bridge is provided with a two-way lane; support beams of the motor vehicle lane bridge are arranged on the motor vehicle direct movement bridge; two ends of the motor vehicle direct movement bridge are provided with a motor vehicle direct movement approach bridge respectively; four right turning bridges are arranged on the motor vehicle direct movement bridge, bridge connection ends of the second right turning bridge and the first right turning bridge are connected with the two-way lane of the motor vehicle direct movement bridge respectively, earth connection ends of the second right turning bridge and the first right turning bridge are connected with a one-way lane of the direct movement motor vehicle lane respectively, and the second right turning bridge and the first right turning bridge are positioned at two sides of the motor vehicle direct movement bridge; bridge connection ends of the third right turning bridge and the fourth right turning bridge are connected with the two-way lane of the motor vehicle direct movement bridge respectively, earth connection ends of the third right turning bridge and the fourth right turning bridge are connected with the one way lane of the direct movement motor vehicle lane respectively, and the third right turning bridge and the fourth right turning bridge are positioned at two sides of the motor vehicle direct movement bridge; and four left turning bridges are arranged on the motor vehicle direct movement bridge.

Description

technical field [0001] The invention relates to an overpass, in particular to a modular left and right turning overpass. Background technique [0002] With the rapid development of urbanization, the urban population has increased rapidly, and people's living standards have also improved rapidly, which has led to a rapid increase in the per capita ownership of private cars. The direct problem brought by the rapid increase in the number of private cars to the city is traffic congestion, especially at traffic intersections. Right-turning vehicles are quickly diverted so that they do not interfere with each other. But, it is unrealistic to construct overpass bridge on original road according to existing bridge construction technology. Its reason is: 1, existing overpass bridge covers an area bigger, respectively builds an overpass bridge at the main traffic crossing place in the city, does not allow on space, and builds existing overpass bridge and also can bring such as demol...

However, it is unrealistic to build an overpass on the original road according to the existing bridge construction technology

Its reason is: 1, existing overpass bridge covers an area bigger, respectively builds an overpass bridge at the main traffic crossing place in the city, does not allow on space, and building existing overpass bridge also can bring such as demolition etc. A series of problems affect the overall planning of the city; 2. The existing overpasses are all made of reinforced concrete and other materials, and the construction period is long. During the long construction process, not only cannot solve the problem of traffic congestion, but will aggravate the traffic congestion situation
