Embodiment Construction

[0010] The following embodiments will further illustrate the present invention in conjunction with the accompanying drawings.

[0011] see figure 1 and 2 , the embodiment of the present invention is a single-layer single viaduct bridge, which can be located on the main road of the road, and is provided with a two-way straight lane bridge deck 1, and the two-way straight lane bridge deck 1 is erected on the pier 2. Two-way straight lane bridge deck 1 is provided with at least one straight lane respectively, and according to factors such as the floor area of ​​the road intersection and the width of the main road, it is best to set up two straight lanes on the two-way straight lane bridge deck respectively. The bridge deck 1 of the straight lane is located at the crossroads, and the two sides are respectively equipped with underbridge forks 3, which are used for vehicles traveling on the bridge deck lane to go down to the bottom of the bridge and turn left. The underbridge forks...

Abstract

The present invention relates to a viaduct bridge for crossroads. It is characterized by that said viaduct bridge has no need of traffic light signal to make traffic control. Said viaduct bridge has two-way straight-going lane bridge floor, on the two-way straight-going lane bridge floor respectively are set at least two lanes, on the outer lanes of two sides of the bridge floor respectively are set forked branch lane for going down from bridge floor and forked branch lane for going up bridge.

Description

technical field [0001] The invention relates to an interconnection design and arrangement of three-dimensional roads, in particular to a viaduct arranged at road intersections without traffic lights. Background technique [0002] With the rapid development of the economy, all kinds of vehicles are also increasing rapidly, which brings huge pressure to urban traffic. Traffic congestion, low efficiency, and frequent accidents have become hot issues in many urban traffic. How to solve the problems existing in urban traffic has become one of the hot spots that the society pays close attention to. For this reason, it is very common to build overpasses and viaducts at crossroads in large and medium-sized cities. Among them, the overpass bridge occupies a large area and engineering quantity, and the cost is high: although the existing viaduct covers an area and the engineering quantity is much smaller than the overpass bridge, and the cost is relatively low, it cannot completely ca...
