Double-layer high-speed overhead flyover for cars

Abstract

A double-layer high-speed overhead flyover for cars is suitable for main roads or secondary main roads. The overhead flyover, corresponding to two directions A and B, is composed of a first bridge floor, a second bridge floor, four ramps, four platforms, and pillars. The overhead flyover is specially-designed for cars and is characterized by miniaturization and low weight, is less in occupied materials and is light in weight and low in cost. The overhead flyover can be manufactured and assembled from steel structures through industrial production in factories, so that a new manufacturing industry entity can be formed. The high-speed overhead flyover achieves single-layer and one-way traffic of cars; according to invention, a high-speed crossroad overhead flyover is linked to a crossroad while a high-speed T-junction overhead flyover is linked to a T-junction. The overhead flyover can create a traffic network without traffic lights for whole city, which would be a wonder of city traffic.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a trolley double-deck high-speed elevated overpass. Background technique [0002] At present, cars are the main means of land transportation; cars are the trend of personal transportation, and even a symbol of personal wealth and status. Few people regard riding a tall horse as an honor. Therefore, there are more and more large and small cars, and the traffic is becoming more and more crowded. Especially at some crossroads in the city, people and vehicles are mixed, either in front or left or right, which can easily cause traffic jams or even traffic accidents. Building overpasses can solve traffic congestion at crossroads, but crossroads are often the most prosperous areas in this area, and every inch of land is expensive, so it is necessary to build overpasses with moderate shapes and less land occupation. [0003] Along with the raising of our people's living stand...

AI Technical Summary

Problems solved by technology

[0015] The design layout of the existing overpass is complex and occupies a large area: the existing reinforced concrete overpass bridge design has many overhead lines with long bends, which easily blurs the driver's direction concept. Correspondingly, there are many hovering overhead bridges, and the natural engineering cost is also large

[0016] Due to the heavy reinforced concrete bridge, complex structure, long construction period, high cost, high construction quality requirements, and the constraints of underground conditions and weather, it is difficult to implement the project construction
