Crossroad 2-shaped two-layer overpass
The invention relates to an overpass which is a crossroad two-layer overpass shaped like a Chinese character'two '. The overpass is provided with 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 two-layer bridge surface of the flyover is 2-shaped. The outline of the second-layer bridge surface of the flyover is a twenty-four-sided polygon defined by twenty-four line segments. And four left turning lanes and four turning parts of the flyover are arranged on the first-layer ground. And four turning lanes and eight turning parts of the overpass are arranged on the first-layer ground. Two north-south straight lanes, a U-turn lane of a south coming vehicle and four right-turn lanes of the overpass are arranged on the ground of the first floor in the whole course. Therefore, the vehicle is safe in driving. The two south-east-west straight lanes of the overpass are arranged on the two-layer bridge surface in the whole course, and vehicles on the overpass run linearly, so that the accident of falling from the overpass does not need to be worried. The overpass is not provided with ramps.
本发明所述立交桥，为十字路口2字形状二层立交桥。立交桥设置十六条车道。十六条车道是：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形状是2字形状。立交桥二层桥面的轮廓，是由二十四条线段围成的二十四边形。立交桥四条左拐弯车道，四个拐弯部位均设置在一层地面。立交桥的四条调头车道，八个拐弯部位均设置在一层地面。立交桥的两条南北向直行车道、南向来车的调头车道、四条右拐弯车道全程在一层地面。因此，车辆行车安全。立交桥的两条南东西向直行车道全程在二层桥面，桥上车辆直线运行，不用担心发生坠桥事故。立交桥没有匝道。
