Clover leaf type interchange structure
The invention provides a clover leaf type interchange structure. The structure comprises a first main road, and a second main road, the upper portion or the lower portion of the second main road intersects with the first main road, and four quadrant areas are formed; the structure further comprises four right-turn ramps which are respectively arranged in the four quadrant areas, and four left-turn ramps, each left-turn ramp comprises a left-turn bent section and a left-turn roundabout section, the left-turn bent section is arranged in a quadrant area, the entrance end of the left-turn bent section is connected with the first main road or the second main road, the left-turn bent section is arranged as a bent arc-shaped lane, the exit end of the left-turn bent section is connected with the entrance end of the left-turn roundabout section, the entrance end of the left-turn roundabout section is arranged in a manner of crossing or penetrating through the first main road or the second main road, and the exit end of the left-turn roundabout section is connected with the right-turn ramp of the previous quadrant area of the first quadrant area. Through the application of the invention, the rapidness, smoothness and safety of vehicles running in two directions on the first main road and the second main road are ensured.
本发明公开了一种苜蓿叶型立交结构，包括：第一主道；第二主道，第二主道的上方或下方与第一主道相交设置，且形成四个象限区域；四右转匝道，四右转匝道分别设置于四象限区域内；四左转匝道，每一左转匝道均包括：左转弯曲段和左转迂回段，左转弯曲段设置一象限区域内，左转弯曲段的入口端与第一主道或第二主道连接，左转弯曲段呈弯曲的弧形车道设置，左转弯曲段的出口端与左转迂回段的入口端连接，左转迂回段的入口端上跨或下穿第一主道或第二主道设置，左转迂回段的出口端与该一象限区域上一象限区域的右转匝道连接。通过对本发明的应用，保证第一主道和第二主道上双向行驶的车辆的快速、畅通、安全。
