Abstract

The invention relates to a crossroad hook-shaped two-layer overpass, which is positioned at a crossroad, has only one second-layer bridge floor and has sixteen lanes. The sixteen lanes comprise four straight lanes, four right turning lanes, four left turning lanes and four turning lanes. The outline of the second-layer bridge surface of the overpass is an octadecagon formed by encirclement of eighteen line segments, and the second-layer bridge surface is in a hook shape. The two east-west through lanes are arranged on the second-layer bridge floor in the whole process, and the four right turning lanes are arranged on the first-layer ground in the whole process. The turning lane of the south coming vehicle is on the ground of the first-layer ground in the whole process. The two north-south straight lanes are arranged on the ground of the first-layer ground in the whole process. Four left turning lanes, two east-west straight lanes, and the turning lane of the north coming vehicle are on the second-layer bridge surface in a one up and one down mode. The turning lane of the east coming vehicle and the turning lane of the west coming vehicle are on the second-layer bridge surface in a two up and two down mode.

Description

technical field [0001] The invention relates to an overpass, more specifically, the present invention relates to a two-story overpass in the shape of a crossroad hook, which is different from the existing overpass. Background technique [0002] Most of domestic crossroad overpasses have ramps, and the overpasses with ramps, when turning left, up and down ramps and turning 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 with a Mazda car on the Balitai overpass, the large truck l...
