Abstract

The invention relates to an overpass which is a right-angled U-shaped two-layer overpass at a crossroad. The overpass is located at a crossroad. The overpass is provided with sixteen lanes including four straight lanes, four right turning lanes, four left turning lanes and four turning lanes. The flyover is only provided with a two-layer bridge floor. The outline of the second-layer bridge surface of the flyover is in a [shape. The invention relates to an octagon which is enclosed by eighteen line segments. And no turning part of the turning lane is arranged on the second-layer bridge floor. And the turning part of each lane is arranged on the first-layer ground. The first, second, fifth, sixth, seventh, eighth and fourteenth lanes of the flyover are on the first floor in the whole course and are not on the second floor. The third lane and the fourth lane are arranged on the second-layer bridge floor in the whole process, and the fifteenth lane, the sixteenth lane, the two-up and two-down second-layer bridge floor, the two east-west through lanes, the U-turn lane of the south coming vehicle and the four left-turn lanes are all one-up and one-down second-layer bridge floors. The overpass is not provided with ramps.

Description

technical field [0001] The present invention relates to a kind of overpass bridge, more specifically, the present invention relates to a kind of two-storey overpass bridge of crossroad U-shape which is different from existing overpass bridges. Background technique [0002] Most of the four left-turn lanes of crossroad overpasses in my country have ramps, and the overpasses with ramps, when turning left, ramp up and down and turn simultaneously. This overpass that develops simultaneously can easily bring accidents of falling from the bridge. For example: at around 18:00 on May 11, 2010, during rush hour, at the southwest corner of the Balitai overpass in Nankai District, Tianjin, a white Xiali car suddenly fell from the bridge while driving. At around 8:20 am on May 24, 2010, a bridge accident occurred on the Balitai Overpass in Tianjin, and a black Santana car fell from the bridge. The driver died at the scene. At about 1 am on May 13, 2013, after a large truck collided w...
