Crossroad staggered cross-shaped two-layer overpass
The invention relates to a crossroad staggered cross-shaped two-layer overpass, which is positioned at a crossroad, is only provided with a two-layer bridge floor, and is provided with sixteen lanes. The crossroad staggered cross-shaped two-layer overpass comprises four straight lanes, four right turning lanes, four left turning lanes and four turning lanes. The two-layer bridge surface of the flyover is dodecagonal, and the outline of the two-layer bridge surface is in a staggered cross shape. The two east-west through lanes are arranged on the second-layer bridge floor in the whole process, and the two south-north through lanes are arranged on the first-layer ground in the whole process. The four left turning lanes are firstly drilled into the bridge opening in the ground of the first floor, then turn left after going out of the bridge opening and then rise to the bridge floor of the second floor through the ramp, or firstly pass through the bridge floor of the second floor and then go down to the ground of the first floor, turn left and turn and then pass through the bridge opening. The four right turning lanes are arranged on the ground of the first floor in the whole process. In the figure 1, the two turning lanes are located on the first-layer ground in the whole course and pass through the second-layer bridge floor. The four turning lanes in the figure 3 and the figure 5 are all located on the ground of the first floor in the whole process.
本发明为十字路口错位十字形状二层立交桥，位于十字路口，只有一个二层桥面，立交桥拥有十六条车道。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。立交桥的二层桥面是个十二边形，二层桥面轮廓是错位十字形状。两条东西向直行车道全程在二层桥面，两条南北向直行车道全程在一层地面。四条左拐弯车道，或者先在一层地面钻进桥洞，出了桥洞之后左拐弯，拐弯之后经由坡道上升至二层桥面，或者先经由二层桥面，然后再下至一层地面，左拐弯，拐弯之后穿越桥洞。四条右拐弯车道，全程在一层地面。图1中两条调头车道全程在一层地面，两条调头车道经由二层桥面。图3、图5中四条调头车道全部全程在一层地面。
