Adjacent quadrant double-ring type deformation clover leaf interchange without interweaving section
The invention discloses an adjacent quadrant double-ring type deformation clover leaf interchange without an interlacing section, which comprises a first main trunk road, a second main trunk road, a third main trunk road and a fourth main trunk road, the second main trunk road is arranged in the north-south direction, the second main trunk road crosses over or passes through the first main trunk road, and four quadrant areas are formed; the four quadrant areas are respectively provided with a right turn ramp; the adjacent quadrant double-ring type deformation cloverleaf interchange without the interlacing section comprises four left-turn ramps, the left-turn ramps comprise two left-turn directional ramps, a first ring-type ramp and a second ring-type ramp, and the first ring-type ramp and the second ring-type ramp are located in adjacent quadrants; the first ring-type ramp is arranged in a quadrant area, and the two ends of the first ring-type ramp are connected with the second main trunk road and the first main trunk road respectively; the second ring-type ramp comprises a left-turn return section and a left-turn annular section, the left-turn return section is located on the outer side of the first ring-type ramp, the two ends of the left-turn return section are connected with the right-turn ramp and the left-turn annular section in a quadrant area respectively, the left-turn return section is connected with the left-turn annular section, and the left-turn annular section overpasses or underpasses a second main trunk road; the left-turn annular section is arranged in a two-quadrant area adjacent to the first quadrant, and the two ends of the left-turn annular section are connected with the left-turn return section and the second main trunk respectively; the right-turn ramp in the first quadrant area is connected with a second ring-type ramp and a left-turn directional ramp, and the second ring-type ramp passes through or crosses the left-turn directional ramp. Optimization is carried out on the basis of a traditional symmetrical double-ring type deformation clover leaf interchange, no interlacing section exists between the double-ring type left-turn ramp entrance and exit, arrangement of collecting and distributing lanes is avoided, the occupied area is lower, and driving of vehicles on a main trunk road is safer.
本发明公开了无交织段的相邻象限双环式变形苜蓿叶立交，包括：第一主要干路，其东西向布置；第二主要干路,其南北向布置，第二主要干路上跨或下穿第一主要干路，且形成四个象限区域；所述四个象限区域分别设有一条右转匝道；所述无交织段的相邻象限双环式变形苜蓿叶立交包括四条左转匝道,所述左转匝道包括两条左转定向匝道及第一环式匝道、第二环式匝道，所述第一环式匝道、第二环式匝道位于相邻象限；所述第一环式匝道设置于一象限区域内，第一环式匝道两端分别连接第二主要干路和第一主要干路；所述第二环式匝道包括左转迁回段和左转环形段，所述左转迁回段位于所述第一环式匝道的外侧，左转迁回段两端分别连接一象限区域内的右转匝道和左转环形段，左转迁回段连接左转环形段路段上跨或下穿第二主要干路，所述左转环形段设置于一象限相邻的二象限区域，左转环形段两端分别连接左转迁回段和第二主要干路；所述一象限区域右转匝道上接有第二环式匝道及一条左转定向匝道，第二环式匝道下穿或上跨该左转定向匝道。本发明在传统对称双环式变形苜蓿叶立交基础上优化，实现了双环式左转匝道出入口之间无交织段，避免设置集散车道，占地更低，主要干路车辆行驶更安全。
