Crossroad hook-shaped two-layer overpass
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.
本发明为十字路口钩子形状二层立交桥，立交桥位于十字路口，立交桥只有一个二层桥面，立交桥拥有十六条车道。十六条车道包括：四条直行车道、四条右拐弯车道、四条左拐弯车道、四条调头车道。立交桥的二层桥面轮廓是由十八条线段围成的十八边形，二层桥面的形状是钩子形状。两条东西向直行车道全程在二层桥面，四条右拐弯车道，全程在一层地面。南向来车的调头车道全程在一层地面。两条南北向直行车道全程在一层地面。四条左拐弯车道、两条东西向直行车道、北向来车的调头车道一上一下二层桥面，东向来车的调头车道、西向来车的调头车道两上两下二层桥面。
