Technical Field

The invention belongs to the field of bridge engineering, and particularly relates to an overpass.

Background

The overpass is called as a three-dimensional cross bridge, and refers to a modern bridge which is built at the junction of more than two cross roads, layered up and down and has no mutual interference in multiple directions, and comprises a sinking tunnel in a three-dimensional cross project. At present, overpasses have become important urban infrastructures in modern bridge engineering. The overpass is basically characterized in that a plurality of layers of roads form a three-dimensional intersection in a three-dimensional space, is a necessary product of urban modernization, and is an indispensable important part in an efficient transportation system in the current society. In order to reduce the influence degree of the vehicles in all directions by the vehicles in other directions, the overpass is required to completely prevent the vehicles in all directions from being interfered by the vehicles in any other directions.

Disclosure of Invention

The invention aims to realize that vehicles in opposite directions are not influenced by vehicles in other directions, and provides a novel overpass type.

The eight-tower overpass comprises eight bridge towers, four curves and a culvert, wherein a first bidirectional lane and a second bidirectional lane are crossed to form a crossroad, the first bidirectional lane descends from the ground level to pass through the culvert at the crossing of the first bidirectional lane and the second bidirectional lane, and a right-turn curve is arranged on the right side of each lane at the crossing of the driving direction in the first bidirectional lane and the second bidirectional lane;

the first bidirectional lane is provided with a fourth bridge tower and an eighth bridge tower on two side road surfaces at the cross intersection, the second bidirectional lane is provided with a second bridge tower and a sixth bridge tower on two side road surfaces at the cross intersection, the third bridge tower is arranged in a region between the fourth bridge tower and the second bridge tower, the fifth bridge tower is arranged in a region between the fourth bridge tower and the sixth bridge tower, the seventh bridge tower is arranged in a region between the sixth bridge tower and the eighth bridge tower, and the first bridge tower is arranged in a region between the second bridge tower and the eighth bridge tower;

one lane in the second bidirectional lanes, which is towards the crossed part, sequentially passes through a third bridge tower, a fourth bridge tower, a sixth bridge tower and a seventh bridge tower and is communicated with the lane in the first bidirectional lane, which is away from the crossed part, to form a left-turn lane, and the other lane in the second bidirectional lanes, which is towards the crossed part, sequentially passes through the seventh bridge tower, the eighth bridge tower, the second bridge tower and the third bridge tower and is communicated with the lane in the first bidirectional lane, which is away from the crossed part, to form a left-turn lane;

one lane in the first bidirectional lane, which is close to the cross, sequentially passes through a fifth bridge tower, a sixth bridge tower, an eighth bridge tower and a first bridge tower and is communicated with a lane in the second bidirectional lane, which is away from the cross, to form a left-turn lane, and the other lane in the first bidirectional lane, which is close to the cross, sequentially passes through the first bridge tower, the second bridge tower, the fourth bridge tower and the fifth bridge tower and is communicated with the lane in the second bidirectional lane, which is away from the cross, to form a left-turn lane.

The eight-tower overpass comprises eight bridge towers, four curved channels and a culvert. The culvert is mainly used for separating vehicles in two vertical directions of a cross road so that the vehicles are not influenced mutually; the curve is used for realizing the right turn of each vehicle driving direction; the eight-seat bridge tower can realize the left turn of each vehicle in the running direction.

The eight-tower overpass can completely realize that vehicles in all directions do not interfere with each other, and can improve the passing efficiency of the vehicles. And the floor area is less, and each lane can flexibly turn left or right, and does not interfere with each other.
