Background technique
目前, 国际国内的城市干道平交十字路口的交通非常拥挤, 经常发生堵塞, 是全世界各 大城市的通病。 究其原因, 是因为两条道路平交, 在交叉点上, 两条道路重叠变成了一条道 路,两条道路上的机动车辆在节点上只能共用一条道,损失了一半的道路资源。再加上行人、 非机动车和机动车混行, 拥堵是必然的结果。 为了解决这个难题, 人们想到了加宽路面, 增 加路口行车道的数量, 但路面不可能无限加宽。 人们又想到了立交桥, 但在现有立文桥设计 方案中, 能使十字路口直行车道和左转弯车道无交叉占道冲突的立交桥最小直径在 120米以 上, 不仅修建成本高, 而且旧城区双向六车道的十字路口都不能修建, 使现在旧城区的十字 路口堵车非常严重, 有的十字路口经常交通瘫痪。  At present, the traffic between the international and domestic urban trunk road crossings is very crowded and often jammed, which is a common problem in major cities around the world. The reason is because the two roads are evenly intersected. At the intersection, the two roads overlap and become a road. The motor vehicles on the two roads can only share one lane on the node and lose half of the road resources. Coupled with the mixed traffic of pedestrians, non-motor vehicles and motor vehicles, congestion is an inevitable result. In order to solve this problem, people think of widening the road surface and increasing the number of intersection lanes, but the road surface cannot be infinitely widened. People think of the overpass, but in the existing Liwenqiao design, the minimum diameter of the overpass that can make the crossroad straight lane and the left turn lane have no cross-track conflict is more than 120 meters, not only the construction cost is high, but also the old city two-way Six-lane intersections cannot be built, making traffic jams at the crossroads of the old city now very serious, and some intersections are often traffic jams.
中国专利 200720043390.6《单层全畅通立交桥》公开了一种在十字路口设一个直跨桥和 一个环形桥的畅通组合结构联合桥。 其缺点: 司机在十字路口必须要认清行车标志, 一旦没 有看清或看清后己不能变道, 会导致在变道交叉点即进十字路口处堵车。 从内向外的直行- -- 左转…右转的道路划分规范不同于现有左转…直行…右转的道路划分规范, 这使司机接近该 立交桥后己来不及变道。 总之, 该立交桥要求的从内向外的直行 ---左转- -右转的道路划分规 范不同于现有左转 ---直行- --右转的道路划分规范, 使该立交桥不能在现有规范的道路上应 用。  China Patent 200720043390.6 "Single-layer Quantongtong Overpass" discloses a smooth joint structure joint bridge with a straight span bridge and a ring bridge at the intersection. Its shortcomings: The driver must recognize the driving sign at the crossroads. Once he has not seen or seen it, he can't change lanes, which will lead to traffic jam at the crossroads of the lane change. Straight line from inside to outside - -- Left turn... Right turn road division specification is different from existing left turn... straight line... right turn road division specification, which makes the driver have no time to change lanes after approaching the overpass. In short, the straight line---left-turn-right-turning road division specification required by the overpass is different from the existing left-turn---right-turn road division specification, so that the overpass cannot be present. There are normative applications on the road.
中国专利 200820230509.5 《直接左、 右转互通立交桥》 公开了一种立交桥, 由于该专利 的权利要求书和说明书对技术方案的描述很不清楚, 但就以说明书附图似乎可理解该网框形 立交桥的结构和缺陷为: 一、增加了不需要的高度和长度:在远离十字路口的地面支道位置, 直行桥从对面的左转弯桥下面穿过后再延续一段桥体才与地面连接, 使上层桥的离地面高度 很高, 增加了桥的总长度, 这样使整个桥体又高又长又大, 浪费建桥费用, 遮挡了城市景观。 二、 局部损坏导致整体损坏: 左转弯桥从左侧地面支道的直行桥和左转弯桥下面穿过后, 与 右侧地面支道的直行桥的下桥段平接后再与地面连接, 也使上层桥的离地面高度很高, 增加 了桥的总长度,还使全部桥体连接为一个大型整体桥,一但该大型整体桥的局部有地质变化, 其局部被损坏就将导致全部大型整体桥损坏。 三、 整个桥成网框形占用面积太大: 左转弯桥 和右转弯桥分别用两个成交叉的桥体, 增加了整个立交桥体宽度, 而且立交桥的整体形状又 为有两条对角线的网框形桥体, 要求十字路口没有建筑物的空地圆形最小直径为 115米, 而 在旧城区的双向六车道十字路口, 直径达到 115米的几乎没有, 也就是该说明书附图提供的 立交桥几乎不能用于旧城区双向六车道十字路口, 即使把左转弯桥和右转弯桥向内凹到最小 半经只有 15.0米, 整个网框形立交桥的最小直径也致少要 75.0米。 发明内容 Chinese Patent 200820230509.5 "Direct Left and Right Turnover Interchange" discloses an overpass. Since the claims and specifications of the patent are unclear about the technical solution, it seems that the frame-shaped overpass can be understood from the drawings. The structure and defects are as follows: 1. Increase the height and length of the unwanted: at the ground branch away from the intersection, The straight bridge passes through the opposite side of the left turn bridge and then continues a section of the bridge to connect with the ground, so that the height of the upper bridge is high from the ground, increasing the total length of the bridge, so that the entire bridge is tall, long and large. Waste the cost of building bridges and obstruct the urban landscape. Second, partial damage leads to overall damage: After the left turn bridge passes under the straight bridge and the left turn bridge of the left ground support, it is connected with the lower bridge of the straight bridge of the right ground support and then connected to the ground. The height of the upper bridge is high from the ground, the total length of the bridge is increased, and all the bridges are connected as a large integral bridge. Once the large integral bridge has geological changes, the partial damage will result in all large The integral bridge is damaged. Third, the entire bridge into the frame shape of the frame is too large: the left turn bridge and the right turn bridge respectively use two intersecting bridges, increasing the width of the entire overpass, and the overall shape of the overpass has two diagonals The frame-shaped bridge body requires that the empty circle with no buildings at the intersection has a minimum diameter of 115 meters, while in the two-way six-lane intersection of the old city, there is almost no diameter of 115 meters, which is provided in the drawings of the specification. The overpass can hardly be used in the two-way six-lane intersection of the old city. Even if the left turn bridge and the right turn bridge are recessed to a minimum of 15.0 meters, the minimum diameter of the entire frame-shaped overpass is 75.0 meters. Summary of the invention
本发明的目的是提供符合现有右行制交通规范的道路车道排列, 在双向六车道的小面积 十字路口能修建, 四个 "卜"字形分叉桥组合成直行车道和左转弯车道无交叉占道冲突, 离 开十字路口的多个车道有较长的合并车道区段而不易堵车的多桥组合式畅通桥; 还提供四个 "卜"字形分叉隧道组合成直行隧道和左转弯隧道无交叉占道冲突, 离开十字路口的多个车 道有较长的合并车道区段而不易堵车的多隧道组合式畅通隧道。 本发明解决交叉占道冲突点的构思是: 把十字交叉路口平面交通的多个冲突点分为三种 冲突点: 第一种是直行车道和对面的左转弯车道有占道冲突; 第二种是四条直行车道分为两 组在十字路口中心区域有交叉占道冲突; 第三种是左转弯车道与该左转弯道所到达地面支道 的直行车道和左转弯车道有交叉占道冲突。  The object of the present invention is to provide a road lane arrangement conforming to the existing right-hand traffic traffic specification, which can be constructed in a two-way six-lane small-area intersection, and four "b"-shaped fork bridges are combined into a straight lane and a left turn lane without cross. Occupy road conflict, multiple lanes leaving the intersection have long merged lane sections and are not easy to jam the multi-bridge combined smooth bridge; also provide four "b" shaped fork tunnels combined into a straight tunnel and a left turn tunnel without Cross-occupation conflicts, multiple lanes leaving the intersection have long merged lane sections and are not prone to traffic jams. The idea of solving the cross-occupation conflict point of the invention is: dividing the plurality of conflict points of the intersection traffic into three types of conflict points: the first type is a straight lane and the opposite left turn lane has a road conflict; There are four straight lanes divided into two groups with cross-track conflicts in the central area of the intersection; the third is that the left-turn lane and the left-turn lane and the left-turn lane of the left-turning lane have cross-track conflicts.
解决第一种, 直行车道和对面的左转弯车道有占道冲突的技术方案: 十字交叉路口的每 个地面支道上的直行桥和左转弯桥为一组, 每组的上桥端都与同一条地面支道连接。 相对直 行的两个直行桥是相互独立的, 使一个直行桥在跨过十字交叉路口后, 经过地面从对面的 "卜"字形分叉形拱桥的左转弯桥下穿过, 解决了直行车道与对面的左转弯车道的交叉冲突 问题。 该技术方案解决了四个占道冲突点。 或者十字交叉路口的每个地面支道下的直行隧道 和左转弯隧道为一组, 每组的进隧道端都与同一条地面支道连接。 相对直行的两个直行隧道 是相互独立的, 使一个直行隧道在穿过十字交叉路口后, 上到地面从对面的 "卜"字形分叉 隧道的左转弯隧道上面跨过, 解决了直行车道与对面的左转弯车道的交叉冲突问题。 该技术 方案解决了四个占道冲突点。 To solve the first type, the straight lane and the opposite left turn lane have a technical solution for occupying the road conflict: the straight bridge and the left turn bridge on each ground branch of the crossroad are a group, and the upper bridge ends of each group are the same A ground branch is connected. The two straight bridges that are relatively straight are independent of each other, so that after a straight bridge crosses the crossroad, it passes through the ground and passes under the left turn bridge of the opposite "b"-shaped bifurcated arch bridge, solving the straight lane and The cross conflict problem of the opposite left turn lane. This technical solution solves four points of conflict. Or a straight tunnel and a left turn tunnel under each ground abutment of a crossroad, each of which is connected to the same ground support. The two straight tunnels that are relatively straight are independent of each other, so that after a straight tunnel passes through the intersection, the fork is crossed from the opposite side to the ground. The tunnel crossed the left turn tunnel, which solved the problem of cross conflict between the straight lane and the opposite left turn lane. This technical solution solves four points of conflict.
解决第二种, 四条直行车道分为两组在十字路口中心区域有交叉占道冲突的技术方案: 交叉行驶的直行车道在十字路口中心部位成立体交通, 解决了四条直行车道在十字路口中心 区域的交通冲突问题。 该技术方案解决了四个占道冲突点。 或者四条直行车道分为两组在十 字路口中心区域有交叉占道冲突的技术方案: 交叉行驶的直行隧道在十字路口中心部位成立 体交通, 解决了四条直行车道在十字路口中心区域的交通冲突问题。 该技术方案解决了四个 占道冲突点。  To solve the second problem, the four straight lanes are divided into two groups of technical schemes for cross-track conflicts in the central area of the intersection: the cross-traveled straight lane establishes body traffic at the center of the intersection, and solves four straight lanes at the intersection center area. The problem of traffic conflicts. This technical solution solves four points of conflict. Or four straight lanes are divided into two groups of technical schemes that have cross-track conflicts in the central area of the intersection: Cross-traveled straight tunnels form body traffic at the center of the intersection, solving the traffic conflicts of the four straight lanes in the central area of the intersection . This technical solution solves four conflicting points.
解决第三种, 是左转弯车道与所到达地面支道的直行车道和左转弯车道有交叉占道冲突 的技术方案: 用左转弯桥的下桥端连通的离开十字路口的地面车道, 从该左转弯桥到达的地 面支道的分叉形拱桥 [直行桥和左转弯桥] 的下面穿过, 解决了左转弯车道与到达的地面支 道的直行车道和左转弯车道的交叉冲突问题。 该技术方案解决了八个占道冲突点。 或者是左 转弯车道与所到达地面支道的直行车道和左转弯车道有交叉占道冲突的技术方案: 用左转弯 隧道的出隧道端连通的离开十字路口的地面车道, 从该左转弯隧道到达的地面支道的分叉隧 道 [直行隧道和左转弯隧道] 的上面跨过, 解决了左转弯车道与到达的地面支道的直行车道 和左转弯车道的交叉冲突问题。 该技术方案解决了八个占道冲突点。  The third solution is to solve the problem that there is a cross-track conflict between the left turn lane and the straight lane and the left turn lane of the grounded branch road: the ground lane leaving the intersection with the lower bridge end of the left turn bridge, from The underside of the bifurcated arch bridge [straight bridge and left turn bridge] of the ground branch that arrives at the left turn bridge passes through, solving the problem of cross conflict between the left turn lane and the straight lane and the left turn lane of the arriving ground branch. The technical solution solved eight occupational conflict points. Or the technical solution of cross-track conflict between the left-turn lane and the straight-line lane and the left-turn lane of the grounded branch road: the ground lane leaving the intersection with the exit tunnel end of the left-turn tunnel, arriving from the left turn tunnel The above-mentioned bifurcated tunnel of the ground branch [straight tunnel and left turn tunnel] crosses over, and solves the problem of cross collision between the left turn lane and the straight lane and the left turn lane of the arriving ground branch. The technical solution solved eight occupational conflict points.
这样, 平面交通的十字路口, 四个直行桥和四个左转弯桥共有的十六个占道冲突点被完 全实现了立体交通, 不再有占道冲突点。 同样, 四个直行车道和四个左转弯车道共有的十六 个占道冲突点被完全实现了立体交通, 不再有占道冲突点。 本发明新功能的构思: 为尽量减少本发明组合桥占用地面和空间, 把行车路线完全可以 相同的左转弯桥和该左转弯桥左侧地面支道的右转弯桥, 用一个能相反方向行驶的左、 右合 并桥,一个左、右转合并桥的宽度比并排的两个单独左转弯桥和右转弯桥的总宽度可减少 5.0 米左右的宽度。 所以, 本发明不用中国专利 200820230509.5 《直接左、 右转互通立交桥》 的 说明书附图所公开的左、 右转是两个独立桥的方式, 而是把左转弯桥设计成左、 右转合并桥 达到减少组合桥占用地面和空间的目的。把行车路线完全可以相同的左转弯隧道和该左转弯 隧道左侧地面支道的右转弯隧道, 用一个能相反方向行驶的左、 右合并隧道, 一个左、 右转 合并隧道的宽度比并排的两个单独左转弯隧道和右转弯隧道的总宽度可减少 5.0米左右的宽 度。 所以, 本发明不用中国专利 200820230509.5 《直接左、 右转互通立交桥》 的说明书附图 所公开的左、 右转是两个独立桥的方式, 而是把左转弯隧道设计成左、 右转合并隧道达到减 少组合隧道占用地面和空间的目的。 In this way, at the intersection of plane traffic, the sixteen road crossing points shared by the four straight bridges and the four left-turning bridges are fully realized with three-dimensional traffic, and there is no longer a road conflict point. Similarly, the sixteen lane conflict points shared by the four straight lanes and the four left-turn lanes are fully realized for three-dimensional traffic, and there is no longer a point of conflict. The concept of the new function of the present invention: In order to minimize the occupation of the ground and space of the composite bridge of the present invention, the right turn bridge which can completely equate the driving route and the right turn bridge of the left ground support of the left turn bridge can be driven in the opposite direction. The left and right merged bridges, the width of one left and right merged bridges can be reduced by a width of about 5.0 meters compared to the total width of two separate left and right turn bridges side by side. Therefore, the present invention does not use the Chinese patent 200820230509.5 "Direct Left and Right Turn Interchange", the left and right turns are two independent bridges, but the left turn bridge is designed as a left and right turn merge bridge. The purpose of reducing the occupation of the ground and space of the combined bridge is achieved. The left-turn tunnel with the same left-turn tunnel and the left-hand branch of the left-turn tunnel, with a left and right merge tunnel that can travel in the opposite direction, one left and right turn merge tunnel is wider than side by side The total width of the two separate left-turn tunnels and right-turn tunnels can be reduced by a width of about 5.0 meters. Therefore, the present invention does not use the Chinese patent 200820230509.5 "Direct Left and Right Turn Interchange", and the left and right turns are two independent bridges, but the left turn tunnel is designed to turn left and right into a tunnel. Reaching Less combined tunnels occupy the ground and space.
为避免中国专利 200820230509.5附图提供的大型立交桥在桥体位置有地质变化,对桥体 一个局部的破坏而导致整个桥体的破坏, 也避免大型立交桥不能用于旧城区双向六车道小型 十字路口的问题, 把可以不相连接的这种大型立交桥分为四个小型的同向分叉 "卜"字形 叉桥, 每个同向分叉 "卜"字形叉桥分别为十字路口的一条地面支道提供左转弯车道和直 行车道。 也就是在能实现十字路口左转弯车和直行车畅通交通的条件下, 把一个大型立交桥 分为四个小型立交桥, 可以大大降低地质变化对桥体的破坏性, 并使个别小型立交桥的破坏 不影响其它小型立交桥的结构和使用。 在旧城十字路口是商业要地, 立交桥对十字路口的商 业有较大影响, 所以本发明用隧道解决十字路口机动车辆的无交叉占道冲突问题, 以便尽量 少地影响十字路口商业, 又使十字路口能不要红绿灯等交通指挥也没有堵车的问题。  In order to avoid the geological changes of the large overpass provided by the Chinese patent 200820230509.5, the local damage of the bridge will cause damage to the whole bridge, and also avoid the large overpass can not be used in the two-way six-lane small intersection of the old city. The problem is that the large overpass that can be disconnected is divided into four small in-situ bifurcated "b"-shaped fork bridges, and each of the same-direction bifurcated "b"-shaped cross-bridges is a ground support at the intersection. Provide left turn lanes and straight lanes. That is to say, under the condition that the left turn and the straight traffic at the intersection can be realized, the division of a large overpass into four small overpasses can greatly reduce the destructiveness of geological changes on the bridge and cause damage to individual small overpasses. Affect the structure and use of other small overpasses. At the crossroads of the old city, it is a commercial place. The overpass has a great influence on the business of the intersection. Therefore, the present invention uses a tunnel to solve the problem of cross-track occupation of cross-road motor vehicles, so as to minimize the cross-road business and make Crossroads can not have traffic lights and other traffic control and there is no traffic jam.
本发明不仅要解决十字路口的行车线路无交叉冲突问题, 还提供在离开十字路口的地面 道路上有足够长的合并车道区段, 解决合并车道在桥上仅仅只有一个点而产生堵车的问题。 十字路口的直行车辆和左转弯车辆不仅要做到没有占道冲突点, 还要做到来自不同地面支道 的直行车辆、 左转弯车辆、 右转弯车辆在离开十字路口地面支道上有多个合并车道点的合并 车道区段。 本发明把合并车道区段设在地面, 虽然合并车道区段是地面道路划分的规则, 不 属于本发明立交桥的结构内容, 但本发明立交桥的结构能使地面支道可以获得合并车道区 段。而中国专利 200820230509.5的说明书附图所公开的网框形立交桥可理解为在离开十字交 中心的多个桥体在一个点合并车道, 使直行车辆、 左转弯车辆和右转弯车辆在桥上只有一个 合并车道点, 这种三条车道在立交桥上同用一个合并车道点, 很易造成在桥上堵车的后果。 而本发明用可提供在地面一定长度的合并车道区段进行车道合并, 能很好的解决来自不同桥 体上的车辆因合并车道点太窄太窄太少而产生的堵车问题。 所以, 本发明不仅可解决十字路 口各条地面支道的直行车辆和左转弯车辆无交叉占道畅通, 还能解决来自不同地面支道桥体 上的车辆在一条地面支道上离开十字路口时, 有很宽裕的地面作为合并车道区段, 相比中国 专利 200820230509.5的说明书附图所公开的网框形立交桥只有一个位置合并车道,则本发明 可成倍减少因合并车道点太窄太窄太少而产生的堵车问题。  The invention not only solves the problem of no cross collision of the traffic lanes at the intersection, but also provides a long enough merged lane section on the ground road leaving the intersection, solving the problem that the merged lane has only one point on the bridge and generates traffic jam. Straight and left turn vehicles at intersections must not only have no road conflicts, but also direct vehicles from different ground supports, left-turn vehicles, and right-turn vehicles with multiple mergers on the ground crossings at the crossroads. The merged lane section of the lane point. The present invention sets the merged lane section on the ground. Although the merged lane section is a rule of ground road division and does not belong to the structural content of the overpass of the present invention, the structure of the overpass of the present invention enables the ground section to obtain a merged lane section. The frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5 can be understood as a combination of multiple bridges leaving the intersection center at one point, so that there is only one on the bridge for the straight-through vehicle, the left-turning vehicle and the right-turning vehicle. Merging lane points, these three lanes use the same lane point on the overpass, which is likely to cause traffic jams on the bridge. However, the present invention uses a combined lane section which can provide a certain length on the ground for lane merging, which can well solve the traffic jam problem caused by the vehicles on different bridges being too narrow and too narrow. Therefore, the present invention can not only solve the problem that the straight-through vehicles and the left-turn vehicles of the ground support roads at the intersections have no cross-over road, but also solve the problem that vehicles from different ground support bridges leave the intersection on a ground support road. There is a very large ground as a merged lane section. Compared with the frame-shaped overpass disclosed in the specification of Chinese Patent No. 200820230509.5, there is only one position merged lane, the invention can be doubled because the merged lane point is too narrow, too narrow and too small. And the traffic jam problem.
本发明新结构的构思: The concept of the new structure of the invention:
一、 左转弯桥不穿过左侧同向分叉 "卜"字形叉桥: 用独立的四个同向分叉 "卜"字 形叉桥, 分叉口两两相对的组成两个分组桥, 两个分组桥的两组直桥单行段成立体十字形交 叉结构, 但每个同向分叉 "卜"字形叉桥的左转弯桥不穿过、不跨过左边的同向分叉 "卜" 字形叉桥, 而是左转弯桥在接近左边的同向分叉 "卜"字形叉桥的高位置区段的下面与地 面连通, 不仅使左转弯桥上的车辆能下到地面, 从地面穿过左边的同向分叉 "卜"字形叉 桥, 还使该左转弯桥与左侧地面支道的右转弯车道连通, 该右转弯车道上的车辆能用该左转 弯桥的外侧桥面实现右转, 把该左转弯桥变为左、 右转两用桥。 1. The left-turning bridge does not pass through the left-hand bifurcation "Bu"-shaped cross-bridge: It uses four independent bifurcations of the "B"-shaped fork bridge, and the two forks are opposite to each other to form two group bridges. Two sets of straight bridge single line segments of two group bridges form a body cross Fork structure, but the left turn bridge of each of the same-direction bifurcated "B"-shaped fork bridge does not pass through, does not cross the left-handed bifurcation "Bu"-shaped fork bridge, but the left turn bridge is close to the left Connected to the ground below the high-position section of the bifurcated "B"-shaped fork bridge, not only enables the vehicle on the left-turning bridge to descend to the ground, but also passes through the left-handed bifurcation "Bu"-shaped fork bridge from the ground. The left turn bridge is also connected to the right turn lane of the left ground support road, and the vehicle on the right turn lane can turn right with the outer bridge deck of the left turn bridge, and turn the left turn bridge into left and right turns Dual-purpose bridge.
左转弯隧道不穿过左侧同向分叉 "卜"字形叉隧道: 用独立的四个同向分叉 "卜"字 形叉隧道, 分叉口两两相对的组成两个分组隧道, 两个分组隧道的两组直隧道单行段成立体 十字形交叉结构, 但每个同向分叉 " 卜"字形叉隧道的左转弯隧道不穿过、 不跨过左边的 同向分叉 "卜"字形叉隧道, 而是左转弯隧道在接近左边的同向分叉 "卜"字形叉隧道的 深位置区段的上面与地面连通, 不仅使左转弯隧道上的车辆能上到地面, 从地面跨过左边的 同向分叉 "卜"字形叉隧道, 还使该左转弯隧道与左侧地面支道的右转弯车道连通, 该右 转弯车道上的车辆能用该左转弯隧道的外侧隧道面实现右转, 把该左转弯隧道变为左、 右转 两用隧道。  The left turn tunnel does not pass through the left side of the same direction bifurcation "Bu" shaped fork tunnel: with four independent diverging forks "B" shaped fork tunnel, the split mouth two pairs of two to form two group tunnels, two The two sets of straight tunnels of the group tunnel form a cross-shaped cross-shaped structure, but the left-turn tunnel of each of the same-direction bifurcated "b"-shaped cross-shaped tunnel does not pass through, and does not cross the left-handed bifurcation "b" The fork tunnel, but the left turn tunnel is connected to the ground above the deep position section of the same-direction bifurcated "b"-shaped fork tunnel near the left, not only enables the vehicle on the left-turn tunnel to reach the ground, but also crosses the ground The left-handed bifurcated "B"-shaped cross-shaped tunnel also connects the left-turn tunnel with the right-turning lane of the left ground tributary, and the vehicle on the right-turning lane can realize the right with the outer tunnel surface of the left-turn tunnel Turn, turn the left turn tunnel into a left and right turn tunnel.
二、 直行拱桥不穿过对面同向分叉 "卜"字形叉桥的左转弯桥: 用独立的四个同向分 叉 "卜"字形叉桥, 分叉口两两相对的组成两个分组桥, 两个分组桥的四个直行拱桥分别 与对面同向分叉 "卜"字形叉桥的左转弯桥在远离十字路口的地面支道位置进行立体交通。 左弯桥单行段的形状是向两个分组桥的两组直桥单行段成立体十字形结构中心区域内凹的 弧形结构, 与其它桥的立交位置也在远离十字路口中心的地面支道, 延长了左转弯桥长度, 从而减少了左转弯桥因坡度需要的桥长要在十字路口占用很大面积的问题, 使十字路口对角 方向建筑物之间的距离只需要 65米以上, 就能满足左转弯桥的需要, 也就能满足本发明组 合畅通桥占用地面和空间的需要。 这就要求相对面的两个同向分叉 "卜"字形叉桥相反方 向行车的两个直行拱桥相互独立、 不用同一个桥, 且有纵向错位, 即一个直行拱桥的下桥段 直桥接地端与对面那一个直行拱桥的地面上桥段共同起桥接地端之间有间隔距离而不在同 一个位置, 直行拱桥的下桥段直桥接地端更接近十字路口中心, 即直桥接地端只要在接近对 面直行拱桥的中段高位置区域或在此之前接地面, 就为对面直行拱桥让出左侧的上方空间, 让对面的左转弯桥直接在左转弯一侧分叉出左弯桥单行段, 实现直行拱桥与对面的左转弯桥 在十字路口以外的地面支道上立体交通。 但直桥单行段不穿过对面左弯桥单行段, 使该位置 的左弯桥单行段下面没有直桥单行段而呈一层桥体的结构。 在十字路口中心, 两个分组桥的 两组直桥单行段成立体交通。 在远离十字路口中心的地面支道上, 每个左弯桥单行段的地面 延长车道都与左转弯所到达的地面支道的同向分叉 "卜"字形叉桥成立体交通, 但左弯桥单 行段不穿过左转弯所到达的地面支道的同向分叉 "卜"字形叉桥。 Second, the straight arch bridge does not pass through the opposite direction of the bifurcation bridge of the "B" shaped fork bridge: with four independent bifurcations of the "B" shaped fork bridge, the two sides of the fork are composed of two groups The bridge, the four straight arch bridges of the two group bridges, and the left-turning bridge of the opposite-facing bifurcated "b"-shaped fork bridge respectively carry out three-dimensional traffic at the position of the ground branch road away from the intersection. The shape of the single section of the left curved bridge is a concave arc-shaped structure in the center of the two sets of straight bridges of the two group bridges, and the intersection position with the other bridges is also the ground branch away from the center of the intersection. , prolonging the length of the left turn bridge, thereby reducing the problem that the bridge length required for the left turn bridge due to the slope needs to occupy a large area at the intersection, so that the distance between the buildings in the diagonal direction of the intersection only needs to be more than 65 meters. The need to meet the left turn bridge can also meet the needs of the combined smooth bridge of the present invention occupying the ground and space. This requires two opposite-direction bifurcated "b"-shaped fork bridges to be driven in the opposite direction. The two straight arches are independent of each other, do not use the same bridge, and have longitudinal misalignment, that is, a straight bridge of a straight arch bridge is grounded. The ground bridge between the end and the opposite straight arch bridge has a separation distance from the bridge ground end and is not at the same position. The straight bridge ground end of the straight bridge is closer to the center of the intersection, that is, the straight bridge ground end In the middle of the high-position area near the opposite straight arch bridge or before the grounding surface, the opposite side arch bridge gives up the upper space on the left side, so that the opposite left-turning bridge directly splits the left-handed bridge single-row section on the left-turn side. , to realize the straight traffic between the straight arch bridge and the opposite left turn bridge on the ground branch outside the intersection. However, the straight section of the straight bridge does not pass through the single-row section of the opposite left-handed bridge, so that there is no straight-line single-segment section under the single-row section of the left-handed bridge at this position and a layered bridge structure is formed. At the center of the intersection, two groups of straight bridges and two separate sections of the two group bridges form body traffic. On the ground branch road away from the center of the intersection, the ground extension lane of each left-handed bridge is in the same direction as the ground branch of the ground branch that reaches the left turn, and the left-handed bridge Single The line segment does not pass through the same direction bifurcated "b" shaped fork bridge of the ground branch that the left turn has reached.
用独立的四个同向分叉 "卜"字形叉隧道, 分叉口两两相对的组成两个分组隧道, 两 个分组隧道的四个直行隧道分别与对面同向分叉 "卜"字形叉隧道的左转弯隧道在远离十 字路口的地面支道位置进行立体交通。左弯隧道单行段的形状是向两个分组隧道的两组直隧 道单行段成立体十字形结构中心区域内凹的弧形结构, 与其它隧道的立交位置也在远离十字 路口中心的地面支道, 延长了左转弯隧道长度, 从而减少了左转弯隧道因坡度需要的隧道长 要在十字路口占用很大面积的问题, 使旧城区小十字路口也能实行车辆不交叉占道畅通。 这 就要求相对面的两个同向分叉 "卜"字形叉隧道相反方向行车的两个直行隧道相互独立、 不用同一个隧道, 且有纵向错位, 即一个直行隧道的出隧道段直隧道接地端与对面那一个直 行隧道的地面下隧道段共同进隧道接地端之间有间隔距离而不在同一个位置, 直行隧道的出 隧道段直隧道接地端更接近十字路口中心, 直隧道接地端只要在接近对面直行隧道的中段深 位置区域接地面, 就为对面直行隧道让出左侧的下方空间, 即让对面的左转弯隧道直接在左 转弯一侧分叉出左弯隧道单行段, 实现直行隧道与对面的左转弯隧道在十字路口以外的地面 支道位置立体交通。只要有一个分组隧道中的两个直隧道单行段的部分出隧道区段位于对面 同向分叉 "卜"字形叉隧道的分叉口之中, 成直隧道单行段部分出隧道区段嵌入对面同向 分叉 "卜"字形叉隧道分叉口之中的结构, 但直隧道单行段不穿过对面左弯隧道单行段, 使该位置的左弯隧道单行段上面没有直隧道单行段而呈一层隧道的结构。 在十字路口中心, 两个分组隧道的两组直隧道单行段成立体交通。 在远离十字路口中心的地面支道下, 每个左 弯隧道单行段的地面延长车道都与左转弯所到达的地面支道的同向分叉 "卜"字形叉隧道 成立体交通, 但左弯隧道单行段不穿过与左转弯所到达的地面支道的同向分叉 "卜"字形 叉隧道。 本发明组合桥的结构是:  Using four independent diverging forks, the "b"-shaped fork tunnel, the two forked tunnels form two group tunnels, and the two straight tunnels of the two group tunnels are respectively bifurcated with the opposite side. The left turn tunnel of the tunnel carries out three-dimensional traffic at the ground branch road away from the intersection. The shape of the single-row segment of the left-bend tunnel is a concave arc-shaped structure in the center of the two-group straight tunnel to the two group tunnels, and the intersection with other tunnels is also located on the ground branch away from the center of the intersection. The length of the left turn tunnel is extended, thereby reducing the problem that the length of the left turn tunnel due to the slope needs to occupy a large area at the intersection, so that the small crossroads in the old city can also implement the vehicle without crossing the road. This requires that the two straight tunnels in the opposite direction of the two opposite-direction bifurcated "b"-shaped fork tunnels are independent of each other, do not use the same tunnel, and have longitudinal misalignment, that is, the straight tunnel of the straight tunnel exits the tunnel. The ground tunnel end of the straight tunnel opposite the opposite side has a separation distance between the tunnel ground end and not at the same position. The straight tunnel ground end of the straight tunnel exit tunnel is closer to the center of the intersection, and the straight tunnel ground end is only Close to the deep grounding area of the middle section of the opposite straight tunnel, the opposite side of the straight tunnel will give up the space on the left side, that is, the opposite left turn tunnel will directly split the left-turn tunnel single-segment on the left turn side to realize the straight tunnel. Stereoscopic traffic with the opposite left turn tunnel at the ground abutment outside the intersection. As long as there is a partial tunnel in the two tunnels, part of the outbound tunnel section is located in the bifurcation of the opposite bifurcation "Bu"-shaped fork tunnel, and the straight section of the straight tunnel is partially embedded in the tunnel section. In the same direction, the structure of the fork of the "B"-shaped fork tunnel is branched, but the straight section of the straight tunnel does not pass through the single-row section of the opposite left-turn tunnel, so that there is no straight section of the single-row section of the left-bend tunnel at the position. The structure of a layer of tunnel. At the center of the intersection, two groups of straight tunnels in two group tunnels form body traffic. Under the ground branch road away from the center of the intersection, the ground extension lane of each left-turn tunnel single-section section is in the same direction as the ground branch road reached by the left turn, and the left-bend is formed. The single-segment of the tunnel does not pass through the same-direction bifurcated fork tunnel of the ground branch that reaches the left turn. The structure of the composite bridge of the present invention is:
左转和直行畅通的四个独立 "卜"字形分叉桥的组合桥, 包括四个分叉形拱桥, 其特征 在于: 每个分叉形拱桥都有一个直行拱桥 2和一个左转弯桥 3, 左转弯桥 3位于直行拱桥 2 的左侧, 左转弯桥 3都在左转弯一侧与直行拱桥 2分叉, 该分叉部位为分叉点 15, 使一个直 行拱桥 2和一个左转弯桥 3组成一个 "卜"字形分叉桥, 则四个分叉形拱桥成为四个同向分 叉 "卜"字形叉桥 1 ;  The combined bridge of four independent "B"-shaped bifurcation bridges, which are left-turned and straight-through, include four bifurcated arch bridges, characterized in that each bifurcated arch bridge has a straight arch bridge 2 and a left turn bridge 3 The left turn bridge 3 is located on the left side of the straight arch bridge 2, and the left turn bridge 3 is branched on the left turn side and the straight arch bridge 2, the branching portion is a bifurcation point 15, so that a straight arch bridge 2 and a left turn bridge 3 to form a "Bu"-shaped bifurcation bridge, then the four bifurcated arch bridges become four identical bifurcation "Bu"-shaped fork bridge 1;
每个同向分叉 "卜 "字形叉桥 1的直行拱桥 2和左转弯桥 3有共同起桥接地端 4, 和共 同起桥接地端 4到分叉点 15之间的两桥并排段 14; 在同向分叉 "卜 "字形叉桥 1中段高位 置区域, 左转弯桥 3与直行拱桥 2分叉; 左转弯桥 3离开直行拱桥 2的高位置区域为分叉段 7; 直行拱桥 2还有一个直桥接地端 5, 左转弯桥 3也还有一个左转桥接地端 6 ; 从分叉点 15 到直桥接地端 5为直桥单行段 8 ; 从分叉点 15到左转桥接地端 6为左弯桥单行段 13 ; The straight arch 2 and the left turn bridge 3 of each of the same-direction bifurcated "b"-shaped fork bridges 1 have a common bridge ground end 4, and two bridges between the common bridge ground end 4 and the branch point 15 are side by side 14 ; in the same direction fork "Bu"-shaped fork bridge 1 mid-high Set the area, the left turn bridge 3 and the straight arch bridge 2 fork; the left turn bridge 3 leaves the straight arch bridge 2 high position area is the split section 7; the straight arch bridge 2 also has a straight bridge ground end 5, the left turn bridge 3 also There is a left turn bridge ground end 6; from the bifurcation point 15 to the straight bridge ground end 5 is a straight bridge single line segment 8; from the bifurcation point 15 to the left turn bridge ground end 6 is a left curved bridge single line segment 13;
分叉口相对的两个同向分叉 "卜"字形叉桥 1组成一个分组桥, 四个同向分叉 "卜" 字形叉桥 1分别组成两个分组桥; 两个分组桥的两组直桥单行段 8成立体十字形结构; 在同 一个分组桥中, 两个直桥单行段 8的部分区段位于对面同向分叉 "卜"字形叉桥 1 的分叉 口之中, 该分组桥成为一个双嵌入式分组桥; 左弯桥单行段 13位于所在的同向分叉 "卜" 字形叉桥 1与左侧同向分叉 "卜 "字形叉桥 1之间。 本发明左转弯桥 3的结构特点使左转弯桥 3成为左、 右转共用桥, 减少组合桥中心区域 的占地面积:左弯桥单行段 13位于所在的同向分叉 "卜"字形叉桥 1与左侧同向分叉 "卜" 字形叉桥 1之间, 即左转弯桥 3的左弯桥单行段 13不穿过、 不跨过本左转弯桥 3左侧的同 向分叉 "卜"字形叉桥 1。 使左转桥接地端 6与左侧的地面支道的右转弯车道连通, 左侧地 面支道的右转弯车可以直接用该左转弯桥 3的外侧作为右转弯桥使用, 实现右转弯。 也就是 相邻地面支道的左转车和右转车可共用左转弯桥 3达到各自转弯的目的, 只是左转车在左转 弯桥 3靠两组直桥单行段 8成立体十字形结构的内侧桥面, 而右转车在靠外侧桥面。 左转车 和右转车共用左转弯桥 3实现左转和右转, 比用左转桥和右转桥两个桥实现左转和右转更少 占用十字路口的地面和空间, 成更小形化的组合桥, 有利于在更小的十字路口可以使用这种 组合桥, 也减少建桥费用。  The two opposite-direction bifurcation "Bu"-shaped fork bridges 1 of the bifurcation port form a group bridge, and the four same-direction bifurcation "Bu"-shaped fork bridges 1 respectively form two group bridges; two groups of two group bridges The straight bridge single-row segment 8 is formed with a body cross-shaped structure; in the same group bridge, the partial segments of the two straight-bridge single-row segments 8 are located in the bifurcation port of the opposite-direction bifurcated "b"-shaped fork bridge 1 The group bridge becomes a double embedded group bridge; the left curved bridge single line segment 13 is located between the same-direction bifurcated "b"-shaped fork bridge 1 and the left-hand bifurcation "b"-shaped fork bridge 1. The structural feature of the left turn bridge 3 of the present invention makes the left turn bridge 3 a left and right turn shared bridge, and reduces the floor area of the center area of the combined bridge: the left curved bridge single line segment 13 is located at the same direction bifurcation "b" shaped fork Between the bridge 1 and the left-hand bifurcation "Bu"-shaped fork bridge 1, that is, the left-turn bridge single-row segment 13 of the left-turning bridge 3 does not pass through, does not cross the same-direction bifurcation on the left side of the left-turning bridge 3 "Bu" shaped fork bridge 1. The left turn bridge ground end 6 is connected with the right turn lane of the left ground support, and the right turn train of the left ground support can be directly used as the right turn bridge for the right turn to realize the right turn. That is to say, the left-turning and right-turning vehicles of the adjacent ground branch can share the left-turning bridge 3 to achieve the purpose of the respective turning, but the left-turning vehicle is in the left-turning bridge 3 and the two sets of straight-bridge single-row sections 8 form a cross-shaped structure. The inside deck is on the right side, while the right turn is on the outside deck. The left turn car and the right turn car share the left turn bridge 3 to achieve left turn and right turn. Compared with the left turn bridge and the right turn bridge, the left turn and the right turn are less occupied by the ground and space of the intersection, and become smaller. The combined bridge helps to use this combination bridge at smaller intersections and also reduces the cost of bridge construction.
本发明直行拱桥 2的结构特点增加合并车道的长度防止堵车: 用独立互不连接的四个同 向分叉 "卜"字形叉桥 1 分叉口两两相对的组成两个分组桥, 两个分组桥的直桥单行段 8 结构形式: 两个分组桥的每个直桥单行段 8的部分区段位于对面同向分叉 "卜 "字形叉桥 1 的分叉口之中, 但不穿过或不跨过对面同向分叉 "卜"字形叉桥 1的左弯桥单行段 13, 该 两个分组桥都为双嵌入式分组桥。这样从直桥单行段 8的直桥接地端 5下桥的直行车辆在地 面, 与从左侧同向分叉 "卜 "字形叉桥 1左转弯桥 3的左转桥接地端 6下桥到地面的左转 弯车辆合并车道, 即来自两个同向分叉 "卜"字形叉桥 1 的直行车辆与左转弯车辆在地面 合并车道,则可以在地面车道的较长一个区段合并车道,而不是仅仅局限于一个合并车道点, 这样可以解决因合并车道的位点太少太窄而造成的堵车问题。 同向分叉 "卜 "字形叉桥 1是指左转弯桥 3与直行拱桥 2有一段并排, 但左转弯桥 3 在直行拱桥 2的中段高位置区域左侧有分叉点 15。 在分叉点 15附近的左转弯桥 3和直行拱 桥 2区段最好有合符交通规范的 4.5米以上净高, 使其下面能通过机动车辆。 左转弯桥 3作 为机动车辆左转弯使用。 "同向"是指每个 "卜"字形叉桥的左转弯桥 3与直行拱桥 2的分 叉方向都相同, 即每个左转弯桥 3都在直行拱桥 2的左侧分叉, 不与其它任何桥体立交而直 接左转。 所以一个同向分叉 "卜"字形叉桥 1 的整体形状是: 一个左转弯桥 3和一个直行 拱桥 2在共同起桥接地端 4到分叉点 15是并排的, 该并排段为两桥并排段 14。 分叉后的直 行拱桥 2为直桥单行段 8, 分叉后的左转弯桥 3为左弯桥单行段 13。 The structural features of the straight arch bridge 2 of the present invention increase the length of the merged lane to prevent traffic jams: four split bridges with two independent joints that are not connected to each other, and the two forked joints form two two bridges, two Straight bridge single row segment of the group bridge 8 Structural form: Part of each of the two bridge bridges is located in the bifurcation of the opposite bifurcation "b" shaped fork bridge 1, but does not wear The left curved bridge single line segment 13 of the "b" shaped fork bridge 1 is crossed or not crossed across the opposite direction, and both of the two group bridges are double embedded packet bridges. Thus, the straight-through vehicle from the lower bridge grounding end 5 of the straight bridge single-segment 8 is on the ground, and the left-handed bridge grounding end 6 of the left-turning bridge 3 from the left side of the bifurcation fork The left-turning vehicle on the ground merges the lane, that is, the straight-through vehicle and the left-turning vehicle from the two-way bifurcated "b"-shaped fork bridge 1 merge the lane on the ground, and the lane can be merged in the longer section of the ground lane. It is not limited to only one merged lane point, which can solve the traffic jam problem caused by too few squares of the merged lanes. The same direction bifurcation "Bu" shaped fork bridge 1 means that the left turn bridge 3 and the straight arch bridge 2 have a side by side, but the left turn bridge 3 There is a bifurcation point 15 on the left side of the middle section high position area of the straight arch 2 . The left turn bridge 3 and the straight arch 2 section near the bifurcation point 15 preferably have a net height of 4.5 meters or more in accordance with the traffic specification so that the underside can pass through the motor vehicle. The left turn bridge 3 is used as a left turn of the motor vehicle. "Same direction" means that the left turn bridge 3 of each "B" shaped fork bridge and the straight arch bridge 2 have the same bifurcation direction, that is, each left turn bridge 3 is bifurcated on the left side of the straight arch bridge 2, not with Any other bridge body interchange and turn left directly. Therefore, the overall shape of a co-forked "b"-shaped fork bridge 1 is: a left-turning bridge 3 and a straight-line arch 2 are side by side at the common bridge grounding end 4 to the bifurcation point 15, and the side-by-side section is two bridges Side by side segment 14. The straight arch bridge 2 after the fork is a straight row single row section 8, and the left turn bridge 3 after the fork is a left line bridge single line section 13.
同一个同向分叉 "卜 "字形叉桥 1的直行拱桥 2和左转弯桥 3的共同起桥接地端 4可 以是一个小区域,则直行拱桥 2起桥点和左转弯桥 3起桥点在相同区域;在这个相同区域中, 直行拱桥 2起桥点和左转弯桥 3起桥点可以是同一位置, 或有一定的前后距离。  The common bridge grounding end 4 of the straight arch bridge 2 and the left turn bridge 3 of the same bidirectional fork "b" shaped fork bridge 1 may be a small area, and the straight arch bridge 2 bridges and the left turn bridge 3 bridge points In the same area; in this same area, the straight arch bridge 2 bridge points and the left turn bridge 3 bridge points can be the same position, or have a certain front and rear distance.
直行拱桥 2是用于十字路口相对面的两条地面支道通行的桥, "直行" 是指机动车辆到 达十字路口对面道路的意义, "直行"不是指桥的形状, 而是指桥的用途。  The straight arch bridge 2 is a bridge for the two ground supports on the opposite side of the intersection. "Straight" refers to the meaning of the motor vehicle reaching the road opposite the intersection. "Straight" does not refer to the shape of the bridge, but refers to the use of the bridge. .
左转弯桥 3 是用于十字路口右行交通制度的左转弯桥, "左转弯"是用途为左转弯的意 义。  The left turn bridge 3 is a left turn bridge for the right traffic system at the intersection, and the "left turn" is the meaning of the left turn.
左转弯桥 3的分叉段 7是用于来自对面的直行拱桥 2的机动车辆从地面穿过通行之用的 桥段,分叉段 7的高度需要满足下面有机动车辆穿过需要的高度,所以同一个同向分叉 "卜" 字形叉桥 1的左转弯桥 3与直行拱桥 2最好在满足交通规范的高位置区域分叉。  The branching section 7 of the left turn bridge 3 is a bridge section for the motor vehicle from the opposite straight arch bridge 2 to pass through the ground, and the height of the branching section 7 needs to meet the height required for the following moving vehicle to pass through. Therefore, the left turn bridge 3 and the straight arch bridge 2 of the same bifurcation "b" shaped fork bridge 1 are preferably bifurcated in a high position area satisfying the traffic specification.
左转桥接地端 6最好位于左转弯要到达的地面支道的同向分叉 "卜"字形叉桥 1 的分 叉点 15附近的地面, 左弯桥单行段 13不穿过、 不跨过左转弯要到达的地面支道的同向分叉 "卜"字形叉桥 1, 以便左转弯机动车辆从地面穿过所到达的地面支道的同向分叉 "卜"字 形叉桥 1。左转弯机动车辆在地面与右侧同向分叉 "卜"字形叉桥 1直行拱桥 2下到地面的 直行车辆合并车道, 可以有较长的合并车道地面区段, 而不是只有一个合并车道点。 避免了 中国专利 200820230509.5说明书附图所公开的网框形立交桥,要使左转弯车辆与右侧地面支 道上来的直行车辆在两个桥的桥体位置合并车道, 由于合并车道点在桥面太少太窄而产生的 堵车问题。  The left turn bridge grounding end 6 is preferably located on the ground near the bifurcation point 15 of the same direction bifurcated "b" shaped fork bridge 1 of the ground branch to which the left turn is to be reached, and the left curved bridge single line segment 13 does not pass through, does not span The same direction bifurcated "B" shaped fork bridge 1 of the ground branch that is to be reached by the left turn, so that the left turn motor vehicle passes from the ground through the same direction forked "B" shaped fork bridge 1 of the arriving ground branch. Left-turning motor vehicles in the ground and the right side of the same direction fork "B" shaped fork bridge 1 straight arch bridge 2 down to the ground straight traffic merge lane, can have a longer merged lane ground section, instead of only one merged lane point . The frame-shaped overpass disclosed in the drawings of the Chinese patent 200820230509.5 is avoided, so that the left-turning vehicle and the straight-through vehicle coming up from the right-hand ground support road merge the lanes at the bridge position of the two bridges, because the merged lane points are on the bridge deck too The problem of traffic jams caused by being too narrow.
同向分叉 "卜"字形叉桥 1的中段设有高位置区域, 以便来自右侧同向分叉 "卜"字 形叉桥 1的左转弯车辆从左转桥接地端 6到地面后从其下面穿过,从而实现本同向分叉 "卜" 字形叉桥 1与来自右侧的左转弯车辆能立体交通。 分组桥是由分叉口相对的两个同向分叉 "卜"字形叉桥 1 的组合结构, 作为十字路口 相对面的两条地面支道的相反方向行驶的直行车实现直行、 和左转弯车实现左转弯的组合 桥。 一个十字路口需要两个分组桥, 两个分组桥的两组直桥单行段 8成立体十字形结构。 The middle section of the same-direction bifurcated "b"-shaped fork bridge 1 is provided with a high-position area, so that the left-turning vehicle from the right-hand bifurcation "b"-shaped fork bridge 1 passes from the left-turn bridge ground end 6 to the ground The following passes through, thereby realizing the three-dimensional traffic of the same-forward bifurcation "b"-shaped fork bridge 1 and the left-turning vehicle from the right side. The group bridge is a combination of two opposite-direction bifurcated "b"-shaped fork bridges 1 opposite to the fork, as an intersection A straight-traveled vehicle traveling in the opposite direction of the opposite ground roads realizes a straight-through, and left-turning vehicle to realize a left-turning combined bridge. Two intersection bridges are required for one intersection, and two sets of straight bridge single row segments 8 of the two group bridges form a body cross structure.
两个分组桥的两组直桥单行段 8成立体十字形结构的 "十字"意义并不限定两个分组桥 的两组直桥单行段 8互相呈 90度角交叉, 这里的 "十字"与十字路口的 "十字"含义相同, 即 "十字"泛指两条道有交叉, 不限定交叉角度。 所以, 直桥单行段 8如果有弯曲也仍然将 两个分组桥的两组直桥单行段 8视为十字形结构。立体十字形结构的形状是指在十字形结构 的上方俯视观察, 两个分组桥的两组直桥单行段 8成立体十字形结构, 但两个分组桥的上下 两组直桥单行段 8并不相连接, 有上下空间距离, 且能满足机动车辆通行。 直桥接地端 5的优选位置: 对于双嵌入式分组桥直桥单行段 8的直桥接地端 5优选位置 是位于接近对面同向分叉 "卜"字形叉桥 1的分叉段 7下方地面位置。 使其直行车辆可 从地面穿过分叉段 7, 则分叉段 7的高度能尽量降低, 即只要一层桥的高度。 左转弯桥 3的优选结构: 左转弯桥 3的左弯桥单行段 13最好是向两个分组桥的两组直 桥单行段 8成立体十字形结构中心区域内凹的弧形结构。 为了延长左弯桥单行段 13的长 度而满足坡度符合交通规范要求, 并尽量少占用十字路口地面或空间位置, 而将左弯桥单行 段 13 的转弯部分设置成向内凹的弧形结构。 这种优选结构使本发明可用于十字路口对角处 建筑物之间只有 65米以上, 并且双向六车道两侧建筑物之间有八车道以上宽度的小型十字 路口, 都能修建本发明的组合畅通桥。 这就使本发明可用于旧城市的干道十字路口, 实现人 们希望的旧城市干道十字路口直行车和左转车无交叉占道畅通。 向内凹弧形的左弯桥单行段 13 最小转弯半径设计: 以两个分组桥的两组直桥单行段 8 成立体十字形结构的中心点为中心, 同一个分组桥向立体十字形结构中心内凹的两个弧形左 弯桥单行段 13相对最短距离长度为 L, 两个弧形左弯桥单行段 13的最小转弯半径为 R, 当 30.0米 : 米的范围内, L和 R的数学关系式为: R = L÷4 + 8。 当 L=60.0米时, R=23.0米。 L越长, 说明十字路口面积越大, 则转弯半径 R可以越大, 弧形左弯桥单行段 13可承受机动车越快的行驶速度。 在十字路口, 由于右行制的右转弯不存在机动车辆之间交叉占道冲突问题, 所以右转弯 不是本发明要解决的主要问题。 从地面右转弯可以不用立交桥, 但要与非机动车和行人有交 叉占道冲突。 为避免该交叉占道冲突, 可将左转弯桥 3的外侧即左侧扩宽, 用于左侧地面支 道的右转弯车使用, 也就是左转弯桥 3成为本地面支道的左转弯车和左侧地面支道的右转弯 车共同使用的两用桥。 左转弯桥 3的结构没有任何变化, 就成为左、 右转两用桥, 使本发明 成为十字路口的四条直行道、 四条左转弯道、 四条右转弯道完全畅通, 没有一个交叉占道冲 突点的全互通组合桥, 即实现了十字路口全部车道畅通的全互通立交桥。 但中国专利 200820230509.5 说明书附图所公开的网框形立交桥要达到十字路口全部车道畅通的立体交 通, 设置了右转弯专用桥, 即右转弯桥和左转弯桥是两个立体交叉并排的桥。 按照立交桥设 计规范, 本发明的左、 右转两用桥的最小宽度可以是 10.0米, 但中国专利 200820230509.5 说明书附图所公开的网框形立交桥的右转弯桥和左转弯桥并排的最小宽度为 16.0米。其结果 是, 单侧实现左、 右转, 本发明减少了 5.0米的占地宽度; 而本发明整个组合桥最小占用地 面和空间的圆直经 65.0米, 比中国专利 200820230509.5说明书附图所公开的网框形立交桥 最小占用地面和空间的圆直经 75.0米减少了 10.0米宽度。 这 10.0米的宽度差, 使本发明的 组合桥可用于几乎任何双向六车道的十字路口, 而有很多的双向六车道的十字路口都不能使 用中国专利 200820230509.5说明书附图所公开的网框形立交桥。也就是说, 使本发明的组合 桥比中国专利 200820230509.5说明书附图所公开的网框形立交桥有更广泛的使用性,使本发 明的组合桥能解决中国专利 200820230509.5 说明书附图所公开的网框形立交桥的任何问题 夕卜,还能解决中国专利 200820230509.5说明书附图所公开的网框形立交桥不能解决的更小十 字路口的立体交通问题。 The "cross" meaning of the two sets of straight bridge single row segments 8 of the two group bridges does not limit the two sets of straight bridge single row segments 8 of the two group bridges intersecting each other at a 90 degree angle, where the "cross" and The "cross" at the intersection has the same meaning, that is, "cross" generally means that the two roads intersect, and the angle of intersection is not limited. Therefore, if there is a bend in the straight section single row section 8, the two sets of straight bridge single line sections 8 of the two group bridges are still regarded as a cross structure. The shape of the three-dimensional cross-shaped structure refers to the top view of the cross-shaped structure. The two sets of straight-line single-row segments 8 of the two group bridges form a body cross-shaped structure, but the upper and lower two sets of straight-bridge single-row segments of the two group bridges are Not connected, there is space between the upper and lower, and can meet the passage of motor vehicles. Preferred position of the straight bridge grounding end 5: For the double-embedded packet bridge, the straight-bridge grounding end 5 of the single-segment 8 is preferably located below the branching section 7 of the opposite-facing bifurcated "b"-shaped fork bridge 1 position. The straight-through vehicle can pass through the branching section 7 from the ground, and the height of the branching section 7 can be reduced as much as possible, that is, as long as the height of one layer of the bridge. Preferred Structure of Left Turning Bridge 3: The left curved bridge single row 13 of the left turn bridge 3 preferably has a concave curved structure in the central portion of the body cross structure to the two sets of straight bridge single row segments 8 of the two grouped bridges. In order to extend the length of the single-row section 13 of the left-bend bridge to meet the requirements of the traffic specification and to occupy the ground or space position of the intersection as little as possible, the turning portion of the single-row section 13 of the left-bend bridge is set to an inwardly concave curved structure. This preferred structure allows the present invention to be used for a combination of the present invention in a small crossroad that is only 65 meters or more between buildings at opposite corners of the intersection and has a width of more than eight lanes between buildings on both sides of the two-way six-lane. Smooth bridge. This makes the invention applicable to the crossroads of the main roads in the old city, and realizes that the old city main road crossroads and the left-turning vehicles have no cross-roads. Inwardly concave curved left curved bridge single row segment 13 Minimum turning radius design: centering on the center point of the two sets of straight bridge single row segments 8 of the two group bridges, the same grouping bridge to the three-dimensional cross structure The two curved left-handed bridges in the center have a relatively short distance of L, and the minimum turning radius of the two curved left-handed bridges is R, which is within the range of 30.0 meters: meters, L and R The mathematical relationship is: R = L÷4 + 8. When L = 60.0 meters, R = 23.0 meters. The longer L is, the larger the crossroads area is, the larger the turning radius R can be, and the curved left curved bridge single row 13 can withstand the faster the speed of the motor vehicle. At the intersection, since the right-turn right turn does not have the problem of cross-track conflict between motor vehicles, the right turn is not the main problem to be solved by the present invention. Turn right from the ground without the overpass, but with non-motorized vehicles and pedestrians The forks occupy the road conflict. In order to avoid the cross-track conflict, the outer side of the left turn bridge 3, that is, the left side is widened, and is used for the right turn train of the left ground support road, that is, the left turn bend bridge 3 becomes the left turn train of the ground support road. A dual-purpose bridge for use with a right-turning vehicle on the left ground support. The structure of the left turn bridge 3 does not change, and it becomes a left-and-right-turning dual-purpose bridge, so that the four straight lanes, the four left-turning lanes, and the four right-turning lanes of the present invention become completely open at the intersection, and there is no cross-track conflict point. The full intercommunication combination bridge, which realizes the full intercommunication overpass with all the lanes at the intersection. However, the frame-shaped overpass disclosed in the drawings of the Chinese patent 200820230509.5 is to achieve the three-dimensional traffic of all the lanes at the intersection, and the right-turning special bridge is set, that is, the right-turning bridge and the left-turning bridge are two three-dimensional cross-side bridges. According to the design specification of the overpass, the minimum width of the left and right turn bridge of the present invention may be 10.0 meters, but the minimum width of the right turn bridge and the left turn bridge of the frame type overpass disclosed in the specification of the Chinese Patent 200820230509.5 is 16.0 meters. As a result, the left side and the right side are realized on one side, and the invention reduces the floor width of 5.0 meters; and the circle of the entire combined bridge occupying the ground and space is 65.0 meters, which is disclosed in the drawings of the Chinese Patent No. 200820230509.5. The frame-shaped overpass minimizes the width of the ground and space by 75.0 meters and reduces the width by 10.0 meters. The width difference of 10.0 meters makes the combined bridge of the present invention applicable to almost any two-way six-lane intersection, and many two-way six-lane intersections cannot use the frame-shaped overpass disclosed in the specification of Chinese Patent No. 200820230509.5. . That is to say, the combined bridge of the present invention has wider applicability than the frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5, so that the combined bridge of the present invention can solve the frame disclosed in the drawings of the Chinese Patent No. 200820230509.5 Any problem with the overpass can also solve the three-dimensional traffic problem at the smaller intersection that cannot be solved by the frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5.
本发明组合隧道的结构是:  The structure of the combined tunnel of the present invention is:
左转和直行畅通的四个 "卜"字形隧道的组合隧道, 包括四个分叉隧道, 其特征在于: 每个分叉隧道都有一个直行隧道 22和一个左转弯隧道 23, 左转弯隧道 23位于直行隧道 22 的左侧, 左转弯隧道 23都在左转弯一侧与直行隧道 22分叉, 该分叉部位为分叉点 35, 使一 个直行隧道 22和一个左转弯隧道 23组成一个 "卜"字形分叉隧道, 则四个分叉隧道成为四 个同向分叉 "卜"字形叉隧道 21 ;  The combined tunnel of the four "B" shaped tunnels, which are left-turned and straight-through, includes four bifurcation tunnels, characterized in that each of the bifurcation tunnels has a straight tunnel 22 and a left turn tunnel 23, and a left turn tunnel 23 Located on the left side of the straight tunnel 22, the left turn tunnel 23 is branched on the left turn side and the straight tunnel 22, and the branching portion is a bifurcation point 35, so that a straight tunnel 22 and a left turn tunnel 23 form a "b" "The glyph-divided tunnel, then the four bifurcation tunnels become the four-way bifurcation "Bu"-shaped fork tunnel 21;
每个同向分叉 "卜"字形叉隧道 21的直行隧道 22和左转弯隧道 23有共同进隧道接地 端 24, 和共同进隧道接地端 24到分叉点 35之间的两隧道并排段 34; 在同向分叉 "卜"字 形叉隧道 21中段深位置区域, 左转弯隧道 23与直行隧道 22分叉; 左转弯隧道 23离开直行 隧道 22的深位置区域为分叉段 27; 直行隧道 22还有一个直隧道接地端 25, 左转弯隧道 23 也还有一个左转隧道接地端 26; 从分叉点 35到直隧道接地端 25为直隧道单行段 28; 从分 叉点 35到左转隧道接地端 26为左弯隧道单行段 33 ; 分叉口相对的两个同向分叉 "卜"字形叉隧道 21组成一个分组隧道,四个同向分叉"卜" 字形叉隧道 21分别组成两个分组隧道; 两个分组隧道的两组直隧道单行段 28成立体十字形 结构; 在同一个分组隧道中, 两个直隧道单行段 28的部分区段分别位于对面同向分叉 "卜" 字形叉隧道 21的分叉口之中, 该分组隧道成为一个双嵌入式分组隧道; 左弯隧道单行段 33 位于所在的同向分叉 "卜"字形叉隧道 21与左侧同向分叉 "卜"字形叉隧道 21之间。 本发明左转弯隧道 23的结构特点使左转弯隧道 23成为左、 右转共用隧道, 减少组合隧 道中心区域的占地面积: 左弯隧道单行段 33位于所在的同向分叉 "卜"字形叉隧道 21与 左侧同向分叉 "卜"字形叉隧道 21之间, 即左转弯隧道 23的左弯隧道单行段 33不穿过、 不跨过本左转弯隧道 23左侧的同向分叉 "卜 "字形叉隧道 21。 使左转隧道接地端 26与左 侧的地面支道的右转弯车道连通, 左侧地面支道的右转弯车可以直接用该左转弯隧道 23 的 外侧作为右转弯隧道使用, 实现右转弯。 也就是相邻地面支道的左转车和右转车可共用左转 弯隧道 23达到各自转弯的目的, 只是左转车在左转弯隧道 23靠两组直隧道单行段 28成立 体十字形结构的内侧隧道面, 而右转车在靠外侧隧道面。左转车和右转车共用左转弯隧道 23 实现左转和右转, 比用左转隧道和右转隧道两个隧道实现左转和右转更少占用十字路口的地 面和地下空间, 成更小形化的组合隧道, 有利于在更小的十字路口可以使用这种组合隧道, 也减少建隧道费用。 The straight tunnel 22 and the left turn tunnel 23 of each of the same-direction bifurcated "b"-shaped fork tunnels 21 have a common tunnel ground end 24, and two tunnel side-by-side sections 34 between the tunnel ground end 24 and the branching point 35. The left turn tunnel 23 and the straight tunnel 22 are bifurcated in the deep position of the middle section of the bifurcated fork tunnel 21; the deep position of the left turn tunnel 23 leaving the straight tunnel 22 is the branching section 27; the straight tunnel 22 There is also a straight tunnel ground end 25, and the left turn tunnel 23 also has a left turn tunnel ground end 26; from the bifurcation point 35 to the straight tunnel ground end 25 is a straight tunnel single line segment 28; from the bifurcation point 35 to the left turn The tunnel ground end 26 is a left curved tunnel single row 33; The two opposite-direction bifurcated "b"-shaped fork tunnels 21 of the bifurcation port form a group tunnel, and the four same-direction bifurcated "b"-shaped fork tunnels 21 respectively form two group tunnels; two groups of two group tunnels The straight tunnel single-section section 28 forms a body cross-shaped structure; in the same group tunnel, the partial sections of the two straight tunnel single-row sections 28 are respectively located in the bifurcation port of the opposite-direction bifurcation "b"-shaped fork tunnel 21, The packet tunnel becomes a double-embedded packet tunnel; the left-bend tunnel single-line segment 33 is located between the same-direction bifurcated "b"-shaped fork tunnel 21 and the left-hand bifurcated "b"-shaped fork tunnel 21. The structural feature of the left turn tunnel 23 of the present invention makes the left turn tunnel 23 a left and right turn shared tunnel, and reduces the floor area of the combined tunnel center area: the left curved tunnel single line segment 33 is located in the same direction bifurcation "b" shaped fork Between the tunnel 21 and the left-hand bifurcation "b"-shaped fork tunnel 21, that is, the left-turn tunnel single-row 33 of the left-turn tunnel 23 does not pass through, does not cross the same-direction bifurcation on the left side of the left-turn tunnel 23 "Bu" shaped fork tunnel 21. The left turn tunnel ground end 26 is connected to the right turn lane of the left ground support, and the right turn train of the left ground support can be directly used as the right turn tunnel by the outside of the left turn tunnel 23 to realize a right turn. That is, the left turn car and the right turn car of the adjacent ground branch can share the left turn tunnel 23 to achieve the purpose of the respective turn, but the left turn car in the left turn tunnel 23 is formed by two sets of straight tunnel single row segments 28 to form a body cross structure. The inner tunnel face, while the right turn car is on the outer tunnel face. Left-turning and right-turning vehicles share the left-turn tunnel 23 to achieve left-turn and right-turn. Compared with the left-turn tunnel and the right-turn tunnel, the left and right turns are less occupied by the ground and underground space of the intersection. The small combination of tunnels facilitates the use of such combined tunnels at smaller intersections and also reduces tunneling costs.
本发明直行拱隧道 22 的结构特点增加合并车道的长度防止堵车: 用独立互不连接的四 个同向分叉 "卜"字形叉隧道 21分叉口两两相对的组成两个分组隧道, 两个分组隧道的直 隧道单行段 28结构形式: 两个分组隧道的每个直隧道单行段 28的部分区段位于对面同向分 叉 "卜"字形叉隧道 21 的分叉口之中, 但不跨过或不穿过对面同向分叉 "卜"字形叉隧 道 21的左弯隧道单行段 33, 该两个分组隧道都为双嵌入式分组隧道。 这样从直隧道单行段 28的直隧道接地端 25出隧道的直行车辆在地面, 与从左侧同向分叉 "卜"字形叉隧道 21 左转弯隧道 23的左转隧道接地端 26出隧道到地面的左转弯车辆合并车道, 即来自两个同向 分叉 "卜"字形叉隧道 21的直行车辆与左转弯车辆在地面合并车道, 则可以在地面车道的 较长一个区段合并车道, 而不是仅仅局限于一个合并车道点, 这样可以解决因合并车道的位 点太少太窄而造成的堵车问题。 同向分叉 "卜"字形叉隧道 21是指左转弯隧道 23与直行隧道 22有一段并排, 但左转 弯隧道 23在直行隧道 22的中段深位置区域左侧有分叉点 35。 在分叉点 35附近的左转弯隧 道 23和直行隧道 22区段最好有合符交通规范的净深空间高度, 使其地表上面能通过机动车 辆。 左转弯隧道 23 作为机动车辆左转弯使用。 "同向"是指每个 "卜"字形叉隧道的左转 弯隧道 23与直行隧道 22的分叉方向都相同, 即每个左转弯隧道 23都在直行隧道 22的左侧 分叉, 不与其它任何隧道立交而直接左转。 所以一个同向分叉 "卜"字形叉隧道 21的整体 形状是: 一个左转弯隧道 23和一个直行隧道 22在共同进隧道接地端 24到分叉点 35是并排 的, 该并排段为两隧道并排段 34。 分叉后的直行隧道 22为直隧道单行段 28, 分叉后的左转 弯隧道 23为左弯隧道单行段 33。 The structural features of the straight arch tunnel 22 of the present invention increase the length of the merged lane to prevent traffic jam: two groups of tunnels are formed by two opposite-direction bifurcated "b"-shaped fork tunnels 21 separated by two independent joints, two Straight tunnel single row segment 28 of a group tunnel: The partial segment of each straight tunnel single row segment 28 of the two group tunnels is located in the bifurcation of the opposite bifurcation "b" shaped fork tunnel 21, but not The left-turn tunnel single-segment 33 of the "b"-shaped fork tunnel 21 is crossed or not crossed by the opposite side, and both of the packet tunnels are double-embedded packet tunnels. Thus, the straight-through vehicle that exits the tunnel from the straight tunnel ground end 25 of the straight section of the straight tunnel 28 is on the ground, and the left-turn tunnel ground end 26 of the left-turn tunnel 23 from the left side of the bifurcated fork tunnel 21 is tunneled to The left-turning vehicle on the ground merges the lanes, that is, the straight-through vehicles and the left-turn vehicles from the two co-forked "b"-shaped fork tunnels 21 merge the lanes on the ground, and the lanes can be merged in the longer section of the ground lane. It is not limited to only one merged lane point, which can solve the traffic jam problem caused by too few squares of the merged lanes. The same-direction bifurcated "b"-shaped fork tunnel 21 means that the left turn tunnel 23 and the straight tunnel 22 are side by side, but the left turn tunnel 23 has a bifurcation point 35 on the left side of the middle deep position area of the straight tunnel 22. Left turn tunnel near bifurcation point 35 The section 23 of the track 23 and the straight tunnel preferably have a net deep space height that conforms to the traffic specification so that the surface of the road can pass through the motor vehicle. The left turn tunnel 23 is used as a left turn of the motor vehicle. "Same direction" means that the left turn tunnel 23 and the straight tunnel 22 of each "b" shaped fork tunnel have the same bifurcation direction, that is, each left turn tunnel 23 is bifurcated on the left side of the straight tunnel 22, not with Turn left at any other tunnel interchange. Therefore, the overall shape of a co-directional bifurcated fork tunnel 21 is: a left turn tunnel 23 and a straight tunnel 22 are side by side at the common tunnel ground end 24 to the branch point 35, and the side by side is two tunnels. Side by side 34. The bifurcated straight tunnel 22 is a straight tunnel single line segment 28, and the bifurcated left turn tunnel 23 is a left curved tunnel single line segment 33.
同一个同向分叉 "卜"字形叉隧道 21的直行隧道 22和左转弯隧道 23的共同进隧道接 地端 24可以是一个小区域, 则直行隧道 22进隧道点和左转弯隧道 23进隧道点在相同区域; 在这个相同区域中, 直行隧道 22进隧道点和左转弯隧道 23进隧道点可以是同一位置, 或有 一定的前后距离。  The common tunnel grounding end 24 of the straight tunnel 22 and the left turn tunnel 23 of the same same bifurcation "b" shaped fork tunnel 21 may be a small area, and the straight tunnel 22 enters the tunnel point and the left turn tunnel 23 enters the tunnel point. In the same area; in this same area, the straight tunnel 22 into the tunnel point and the left turn tunnel 23 into the tunnel point may be the same position, or have a certain front-to-back distance.
直行隧道 22是用于十字路口相对面的两条地面支道通行的隧道, "直行" 是指机动车 辆到达十字路口对面道路的意义, "直行"不是指隧道的形状, 而是指隧道的用途。  The straight tunnel 22 is a tunnel for the two ground supports on the opposite side of the intersection. "Straight" refers to the meaning of the motor vehicle reaching the road opposite the intersection. "Straight" does not refer to the shape of the tunnel, but refers to the use of the tunnel. .
左转弯隧道 23是用于十字路口右行交通制度的左转弯隧道, "左转弯"是用途为左转弯 的意义。  The left turn tunnel 23 is a left turn tunnel for the right traffic system at the intersection, and the "left turn" is the meaning of the left turn.
左转弯隧道 23的分叉段 27是用于来自对面的直行隧道 22的机动车辆从地面过通行之 用的隧道段, 分叉段 27 的深度需要满足上面有机动车辆通行需要的深度, 所以同一个同向 分叉 "卜 "字形叉隧道 21的左转弯隧道 23与直行隧道 22最好在满足交通规范的深位置区 域分叉。  The branching section 27 of the left turn tunnel 23 is a tunnel section for the motor vehicle from the opposite straight tunnel 22 to pass through the ground. The depth of the branching section 27 needs to meet the depth required for the above-mentioned organic moving vehicle, so The left turn tunnel 23 and the straight tunnel 22 of a co-directional bifurcated "b" shaped fork tunnel 21 preferably diverge in a deep position region that satisfies the traffic specification.
左转隧道接地端 26最好位于左转弯要到达的地面支道的同向分叉 "卜"字形叉隧道 21 的分叉点 35附近的地面, 左弯隧道单行段 33不跨过、 不穿过左转弯要到达的地面支道的同 向分叉 "卜"字形叉隧道 21, 以便左转弯机动车辆从地面跨过所到达的地面支道的同向分 叉 "卜"字形叉隧道 21。 左转弯机动车辆在地面与右侧同向分叉 "卜"字形叉隧道 21直行 隧道 22 的直行车辆合并车道, 可以有较长的合并车道地面区段, 而不是只有一个合并车道 点。 避免了合并车道点在隧道下面太少太窄而产生的堵车问题。  The left-turn tunnel grounding end 26 is preferably located on the ground near the bifurcation point 35 of the same-direction bifurcated "b"-shaped fork tunnel 21 of the ground branch to which the left turn is to be reached, and the left-turn tunnel single-section 33 does not cross or wear The same direction bifurcation "b" shaped fork tunnel 21 of the ground branch to be reached by the left turn, so that the left turn motor vehicle crosses the same direction bifurcated "b" shaped fork tunnel 21 from the ground to the ground branch. A left-turning motor vehicle splits the ground and the right side of the same direction. The "b"-shaped cross-section tunnel 21 straight-through tunnel 22's straight-vehicle merged lanes can have longer merged lane ground sections instead of only one merged lane point. It avoids the traffic jam problem caused by the merger lane point being too small and too narrow under the tunnel.
同向分叉 "卜"字形叉隧道 21的中段设有深位置区域, 以便来自右侧同向分叉 "卜" 字形叉隧道 21的左转弯车辆从左转隧道接地端 26到地面后从其上面跨过, 从而实现本同向 分叉 "卜"字形叉隧道 21与来自右侧的左转弯车辆能立体交通。 分组隧道是由分叉口相对的两个同向分叉 "卜"字形叉隧道 21的组合结构, 作为十字 路口相对面的两条地面支道的相反方向行驶的直行车实现直行、和左转弯车实现左转弯的组 合隧道。 一个十字路口需要两个分组隧道, 两个分组隧道的两组直隧道单行段 28成立体十 字形结构。 The middle section of the same-direction bifurcated "b"-shaped fork tunnel 21 is provided with a deep position area so that the left-turning vehicle from the right-hand bifurcation "b"-shaped fork tunnel 21 goes from the left-turn tunnel ground end 26 to the ground The above crosses, thereby realizing the three-dimensional traffic of the same-forward bifurcation "b"-shaped fork tunnel 21 and the left-turning vehicle from the right side. The group tunnel is a combination of two opposite-direction bifurcated "b"-shaped fork tunnels 21 opposite to the fork, as a cross A straight-through vehicle traveling in the opposite direction of the two ground supports on the opposite side of the intersection realizes a combined tunnel for the straight turn and the left turn to realize the left turn. Two intersection tunnels are required for one intersection, and two groups of direct tunnel single row segments 28 of two group tunnels form a body cross structure.
两个分组隧道的两组直隧道单行段 28成立体十字形结构的 "十字"意义并不限定两个 分组隧道的两组直隧道单行段 28互相呈 90度角交叉, 这里的 "十字"与十字路口的 "十字" 含义相同, 即 "十字"泛指两条道有交叉, 不限定交叉角度。 所以, 直隧道单行段 28如果 有弯曲也仍然将两个分组隧道的两组直隧道单行段 28视为十字形结构。 但两个分组隧道的 上下两组直隧道单行段 28并不相连接, 有上下高差距离, 且能满足两隧道中的机动车辆通 行。 直隧道接地端 25的优选位置: 对于双嵌入式分组隧道直隧道单行段 28的直隧道接地端 25优选位置是位于接近对面同向分叉 "卜"字形叉隧道 21的分叉段 27上方地面位置。 使 其直行车辆可从地面跨过分叉段 27, 则分叉段 27的深度能尽量减少。 左转弯隧道 23的优选结构: 左转弯隧道 23的左弯隧道单行段 33最好是向两个分组隧 道的两组直隧道单行段 28成立体十字形结构中心区域内凹的弧形结构。 为了延长左弯隧 道单行段 33的长度而满足坡度符合交通规范要求, 并尽量少占用十字路口地面或地下位置, 而将左弯隧道单行段 33 的转弯部分设置成向内凹的弧形结构。 这种优选结构使本发明可用 于十字路口对角处建筑物之间只有 65米以上, 并且双向六车道两侧建筑物之间有八车道以 上宽度的十字路口, 都能修建本发明的组合畅通隧道。 这就使本发明可用于旧城市的干道十 字路口, 实现人们希望的旧城市干道十字路口直行车和转大车无交叉占道畅通。 向内凹弧形的左弯隧道单行段 33最小转弯半径设计: 以两个分组隧道的两组直隧道单 行段 28成立体十字形结构的中心点为中心, 同一个分组隧道向立体十字形结构中心内凹的 两个弧形左弯隧道单行段 33相对最短距离长度为 L, 两个弧形左弯隧道单行段 33的最小转 弯半径为 R, 当 30.0米 L 80.0米的范围内, L和 R的数学关系式为: R = L÷4 + 8。 当 L=60.0米时, R=23.0米。 L越长, 说明十字路口面积越大, 则转弯半径 R可以越大, 弧形 左弯隧道单行段 33可承受机动车越快的行驶速度。 在十字路口, 由于右行制的右转弯不存在机动车辆之间交叉占道冲突问题, 所以右转弯 不是本发明要解决的主要问题。 从地面右转弯可以不用立交隧道, 但要与非机动车和行人有 交叉占道冲突。 为避免该交叉占道冲突, 可将左转弯隧道的外侧即左侧扩宽, 用于左侧地面 支道的右转弯车使用, 也就是左转弯隧道成为本地面支道的左转弯车和左侧地面支道的右转 弯车共同使用的两用隧道。 左转弯隧道的结构没有任何变化, 就成为左、 右转两用隧道, 使 本发明成为十字路口的四条直行道、 四条左转弯道、 四条右转弯道完全畅通, 没有一个交叉 占道冲突点的全互通组合隧道, 即实现了十字路口全部车道畅通的全互通立交隧道。 但中国 专利 200820230509.5 说明书附图所公开的网框形立交桥要达到十字路口全部车道畅通的立 体交通, 设置了右转弯专用桥, 即右转弯桥和左转弯桥是两个立体交叉并排的桥。 按照立交 桥或隧道设计规范, 本发明的左、 右转两用隧道的最小宽度可以是 10.0 米, 但中国专利 200820230509.5 说明书附图所公开的网框形立交桥的右转弯桥和左转弯桥并排的最小宽度 为 15.0米。 其结果是, 单侧实现左、 右转, 本发明减少了 5.0米的占地宽度; 而本发明整个 组合隧道最小占用地面的圆直经 65.0米, 比中国专利 200820230509.5说明书附图所公开的 网框形立交桥最小占用地面的圆直经 75.0米减少了 10.0米宽度。 这 10.0米的宽度差, 使本 发明的组合隧道可用于几乎任何双向六车道的十字路口, 而有很多的双向六车道的十字路口 都不能使用中国专利 200820230509.5说明书附图所公开的网框形立交桥。也就是说, 使本发 明的组合隧道比中国专利 200820230509.5 说明书附图所公开的网框形立交桥有更广泛的使 用性,使本发明的组合隧道能解决中国专利 200820230509.5说明书附图所公开的网框形立交 桥的任何问题外,还能解决中国专利 200820230509.5说明书附图所公开的网框形立交桥不能 解决的更小十字路口的立体交通问题。 本发明所述的左边或右边、 左面或右面、 左侧右侧的 "左" "右"是指人站在某一个同 向分叉 "卜"字形叉桥 1的共同起桥接地端 4位置, 面对对面同向分叉 "卜"字形叉桥 1 的共同起桥接地端 4去判断 "左"或 "右"; 或是指人站在某一个同向分叉 "卜"字形叉隧 道 21的共同进隧道接地端 24位置, 面对对面同向分叉 "卜"字形叉隧道 21的共同进隧道 接地端 24去判断 "左"或 "右"。 The two groups of straight tunnels of two groups of tunnels form a "cross" meaning of the cross-shaped structure. The two sets of straight tunnels of the two grouped tunnels are not perpendicular to each other. The two cross-sections 28 intersect at a 90-degree angle to each other. The "cross" at the crossroads has the same meaning, that is, "cross" generally means that the two roads intersect, and the angle of intersection is not limited. Therefore, the straight tunnel single line segment 28 still treats the two sets of straight tunnel single line segments 28 of the two group tunnels as a cross structure if there is a bend. However, the upper and lower two straight tunnels of the two group tunnels are not connected to each other, and there is an upper and lower height difference distance, and can satisfy the passage of motor vehicles in the two tunnels. Preferred position of the straight tunnel ground end 25: The direct tunnel ground end 25 for the double embedded packet tunnel straight tunnel single row 28 is preferably located above the branching section 27 of the opposite facing bifurcated "b" shaped fork tunnel 21 position. By allowing the straight-through vehicle to cross the fork section 27 from the ground, the depth of the split section 27 can be minimized. Preferred Structure of Left Turn Tunnel 23: The left curved tunnel single row 33 of the left turn tunnel 23 preferably has a concave arcuate structure in the central portion of the body cross-shaped structure to the two sets of straight tunnel single row segments 28 of the two grouped tunnels. In order to extend the length of the single-row section 33 of the left-bend tunnel to meet the requirements of the traffic specification and to occupy the ground or underground position of the intersection as little as possible, the turning portion of the single-row section 33 of the left-bend tunnel is set to an inwardly concave curved structure. The preferred structure allows the present invention to be used for intersections between buildings at opposite corners of the intersection, and for intersections of more than eight lanes between buildings on both sides of the two-way six-lane, the combination of the present invention can be constructed. tunnel. This makes the invention applicable to the crossroads of the main roads of the old city, and realizes that the old city trunk roads at the crossroads of the old city and the big cars do not cross the road. Design of the minimum turning radius of the single curved section of the left curved tunnel 33 which is concavely curved inwardly: centering on the center point of the body cross-shaped structure of two sets of straight tunnel single-row sections 28 of two group tunnels, the same grouping tunnel to the three-dimensional cross structure The two curved left-bend tunnel single-row 33 in the center has a relatively short distance L, and the minimum turning radius of the two curved left-bend tunnel single-row 33 is R, when 30.0 meters L is 80.0 meters, L and The mathematical relationship of R is: R = L÷4 + 8. When L = 60.0 meters, R = 23.0 meters. The longer the L, the larger the cross-sectional area, the larger the turning radius R, and the curved left-turn tunnel single-row 33 can withstand the faster the speed of the motor vehicle. At the crossroads, since the right-turn right turn does not have cross-track conflicts between motor vehicles, right turn It is not the main problem to be solved by the present invention. Turning right from the ground can eliminate the need for a crossover tunnel, but it has to cross the road with non-motor vehicles and pedestrians. In order to avoid the cross-track conflict, the outer side of the left-turn tunnel can be widened, and the right-turning vehicle for the left ground support can be used, that is, the left-turn tunnel becomes the left-turning vehicle and the left of the ground branch. A dual-purpose tunnel used by a right-turning vehicle for a side ground support. The structure of the left turn tunnel has not changed, and it becomes a left-to-right turn tunnel. The four straight lanes, four left-turning lanes and four right-turning lanes of the present invention are completely unblocked at the intersection, and there is no cross-track conflict point. Fully intercommunication combined tunnels, that is, full-interchange interchange tunnels that open all lanes at intersections. However, the frame-shaped overpass disclosed in the drawings of the Chinese patent 200820230509.5 is to achieve the three-dimensional traffic of all the lanes at the intersection, and the right-turning special bridge is set, that is, the right-turning bridge and the left-turning bridge are two three-dimensional cross-side bridges. According to the overpass or tunnel design specification, the minimum width of the left and right turn tunnel of the present invention may be 10.0 meters, but the right turn bridge and the left turn bridge of the frame type overpass disclosed in the drawings of the Chinese Patent 200820230509.5 are the smallest side by side. The width is 15.0 meters. As a result, the left side and the right side are realized on one side, and the invention reduces the floor width of 5.0 meters; and the circle of the entire combined tunnel occupying the ground of the invention is straight through 65.0 meters, which is wider than the network disclosed in the specification of Chinese Patent No. 200820230509.5. The frame-shaped overpass minimizes the width of the ground by a distance of 10.0 meters. The width difference of 10.0 meters makes the combined tunnel of the present invention applicable to almost any two-way six-lane intersection, and many two-way six-lane intersections cannot use the frame-shaped overpass disclosed in the drawings of Chinese Patent No. 200820230509.5. . That is to say, the combined tunnel of the present invention has wider applicability than the frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5, so that the combined tunnel of the present invention can solve the frame disclosed in the specification of the Chinese Patent No. 200820230509.5 In addition to any problems of the overpass, it can also solve the three-dimensional traffic problem of smaller intersections that cannot be solved by the frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5. The left side or the right side, the left side or the right side, and the left side right side of the present invention are "left" and "right", which means that the person stands on the grounding end 4 of the common bridge of the same-forward bifurcated "b"-shaped fork bridge 1. In the face of the opposite direction, the common bridge grounding end of the "b"-shaped fork bridge 1 is judged as "left" or "right"; or the person standing in a same direction bifurcation "b" shaped fork tunnel At the joint grounding end 24 position of 21, the common tunneling ground end 24 of the opposite-direction bifurcated "b"-shaped fork tunnel 21 is judged to be "left" or "right".

The bridge, but has a horizontally significant uphill and downhill slope, so the shape of the straight arch 2 can be a straight shape or a curved shape. When the bridge is actually built, the shape of the straight arch 2 is determined based on the shape of the ground road. The straight tunnel 22 refers to a tunnel in which the direction of travel of the motor vehicle in the tunnel is straight for the purpose of crossing the intersection, but has a downslope and an uphill slope in a horizontal depth sense, so the shape of the straight tunnel 22 may be a straight shape or The curved shape, when the tunnel is actually built, the shape of the straight tunnel 22 is determined based on the shape of the ground road.

一、 把大型立交桥分为四个小型 "卜"字形立交桥, 减少地质变化的灾害程度: 中国专 利 200820230509.5《直接左、 右转互通立交桥》 的说明书附图所公开的网框形立交桥是连为 一体的一个整体大型立交桥, 一个整体大型立交桥的总长度很长, 占地面积很大, 当在总长 度和占地面积内有地质变化, 就会对该立交桥产生破坏, 导致整个大型立交桥不能使用, 该 十字路口交通完全瘫痪。而本发明把上述的整体大型立交桥拆分为四个独立不相连接的同向 分叉 "卜"字形叉桥即小型立交桥, 用这四个小型立交桥分别完成十字路口四条地面支道 道路的左转和直行畅通功能, 在相同的行车时速、 相同的桥体坡度等技术参要条件下, 相比 中国专利 200820230509.5说明书附图的大型网框立交桥,本发明的每个小型立交桥比现在的 大型立交桥的总长度缩短 30-35%, 四个小型立交桥占地总面积减少 30-50%; 很少占用地面 支道以外的地面, 以及该地面的地下和地上空间; 也就是本发明大大减小了局部损坏导至整 体损坏的程度; 由于本发明是独立的四个小型立交桥, 即便有地质变化对某个小型立交桥造 成破坏不能使用, 也不会导至不相连接的其它桥受损坏, 这样大大减小了地质变化造成损坏 的经济损失, 也能使十字路口的交通不会完全瘫痪; 总之, 本发明用小型立交桥比现有的大 型立交桥, 大大降低了地质灾害的风险。 1. Divide the large overpass into four small "B" shaped overpasses to reduce the degree of geological changes: The Chinese-style patent 200820230509.5 "Direct Left and Right Turnover Interchange" An overall large overpass, an overall large overpass has a long overall length and a large footprint. When there is a geological change in the total length and floor space, the overpass will be damaged, resulting in the entire large overpass being unusable. The traffic at the intersection is completely paralyzed. The present invention splits the above-mentioned integral large overpass into four independent non-connected co-directional bifurcation "Bu"-shaped fork bridges, that is, small overpasses, and the four small overpasses respectively complete the left of the four ground crossing roads at the intersection Rotating and straight-through function, under the technical conditions of the same driving speed, the same bridge slope, etc., compared with the large-scale frame overpass of the Chinese patent 200820230509.5, the small overpass of the present invention is larger than the current large overpass The total length is shortened by 30-35%, and the total area of the four small overpasses is reduced by 30-50%; the ground outside the ground support is rarely occupied, and the underground and above-ground space of the ground; that is, the invention is greatly reduced The degree of local damage leads to the overall damage; since the invention is independent of four small overpasses, even if there are geological changes that can cause damage to a small overpass, it will not lead to damage to other bridges that are not connected, so Reduce the economic loss caused by geological changes, and also make the traffic at the intersection not completely paralyzed; Out with a small interchange is larger than the conventional Overpasses greatly reduce the risk of geological disasters.

Miniaturization can take less of the ground outside the ground tributaries and the underground and above ground spaces of the ground.
二、 左转弯桥可以作为左转弯和右转弯共用桥: 左转弯桥的左转桥接地端与左侧地面支 道的右转弯车道相连通, 左转弯桥就可以作为左侧地面支道的右转弯车的共用桥。 左转弯和 右转弯共用桥的最小桥面宽度比用左转桥和右转桥两个独立桥的总宽度要减少 5.0米左右。 中国专利 200820230509.5 的说明书附图所公开的网框形立交桥的左转桥和右转桥是两个独 立桥。所以, 本发明整个组合桥最小占用地面的圆直经 65.0米, 比中国专利 200820230509.5 说明书附图所公开的网框形立交桥最小占用地面和空间的圆直经 75.0米减少了 10.0米宽度。 则本发明的组合桥能用于更小的十字路口, 可使用的范围更广。  2. The left turn bridge can be used as a left turn and a right turn shared bridge: The left turn bridge ground end of the left turn bridge is connected to the right turn lane of the left ground support, and the left turn bridge can be used as the right side of the left ground support. The shared bridge of the turning car. The minimum bridge width of the left-turn and right-turn shared bridges is reduced by about 5.0 meters compared to the total width of the two independent bridges of the left-turn and right-turn bridges. The left turn bridge and the right turn bridge of the frame-shaped overpass disclosed in the drawings of the Chinese patent 200820230509.5 are two independent bridges. Therefore, the circle of the entire composite bridge of the present invention occupies a minimum of 65.0 meters, which is less than the width of 10.0 meters, which is smaller than the 75.0 meters of the frame-shaped overpass disclosed in the drawings of the Chinese Patent 200820230509.5. The composite bridge of the present invention can then be used for smaller intersections and can be used in a wider range.
左转弯隧道的左转隧道接地端与左侧地面支道的右转弯车道相连通, 左转弯隧道就可以 作为左侧地面支道的右转弯车共用隧道。左转弯和右转弯共用隧道的最小隧道面宽度比用左 转隧道和右转隧道两个独立隧道的总宽度要减少 5.0米左右。 中国专利 200820230509.5的说 明书附图所公开的网框形立交桥的左转桥和右转桥是两个独立桥。 所以, 本发明整个组合隧 道最小占用地面和地下空间的圆直经 65.0米, 比中国专利 200820230509.5说明书附图所公 开的网框形立交桥最小占用地面和空间的圆直经 75.0米减少了 10.0米宽度。 则本发明的组 合隧道能用于更小的十字路口, 可使用的范围更广。  The left turn tunnel grounding end of the left turn tunnel is connected to the right turn lane of the left ground support road, and the left turn tunnel can be used as the right turn turn common tunnel of the left ground support. The minimum tunnel face width of the left-turn and right-turn shared tunnels is reduced by about 5.0 meters compared to the total width of the two independent tunnels of the left-turn tunnel and the right-turn tunnel. The left turn bridge and the right turn bridge of the frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5 are two independent bridges.

The combined tunnel of the present invention can then be used for smaller intersections and can be used in a wider range.
三、 离开十字路口的车辆有较宽的地面作为合并车道区段: 从直桥单行段的直桥接地端 下桥的直行车辆在地面直行并从对面的同向分叉 "卜"字形叉桥左转弯桥下面穿过, 与从 左侧同向分叉 "卜"字形叉桥的左转弯桥下桥到地面的左转弯车辆合并车道, 则可以在较 长的一个地面区段合并车道,避免了中国专利 200820230509.5的说明书附图所公开的网框形 立交桥在桥体上合并车道位置太小太窄而导致的堵车问题。  3. The vehicle leaving the intersection has a wider ground as the merged lane section: The straight-through vehicle from the straight bridge of the straight section of the straight section of the straight bridge goes straight on the ground and branches from the opposite side of the "B" shaped fork bridge Passing under the left-turning bridge, merged with the left-turning vehicle under the bridge from the left-handed bridge of the "b"-shaped fork bridge from the left side to the ground, you can merge the lanes in the longer one of the ground sections to avoid The frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5 incorporates a problem of traffic jams on the bridge body where the lane position is too small and too narrow.
从直隧道单行段的直隧道接地端出隧道的直行车辆在地面直行并从对面的同向分叉 "卜"字形叉隧道左转弯隧道上面跨过, 与从左侧同向分叉 "卜"字形叉隧道的左转弯隧 道出隧道到地面的左转弯车辆合并车道, 则可以在较长的一个地面区段进行合并车道, 避免 了中国专利 200820230509.5 的说明书附图所公开的网框形立交桥在桥体上合并车道位置太 小太窄而导致的堵车问题。  The straight-through vehicle that exits the tunnel from the straight tunnel ground of the straight section of the straight tunnel goes straight on the ground and crosses the tunnel from the opposite direction of the opposite direction of the "B"-shaped fork tunnel to the left turn, and the fork in the same direction from the left side. In the left-turn tunnel of the glyph tunnel, the left-turning vehicle merged lane from the tunnel to the ground, the merged lane can be merged in the longer ground section, avoiding the frame-shaped overpass disclosed in the specification of Chinese Patent 200820230509.5. The traffic jam on the body is too small and too narrow.
四、 基本同于平面交通原线路而无多余绕行: 能使双向六车道十字路口直行机动车道和 左转弯车机动道无交叉占道畅通, 解决了在十字路口因两条道路平交而产生的堵车、 堵塞交 通问题。这是一种没有多余绕行线路,在十字路口机动车辆仅有上坡和下坡不同于平面交通, 而行车线路基本同于现行有红绿灯的平面道路上的行车线路, 不改变人们在平交十字路口的 行车方向和习惯, 不会在十字路口的通行过程中因多余的绕行而迷失方向, 另外修建桥或隧 道的工程量少于现有的任何全互通立交桥或隧道, 节约建桥工程费用。 Fourth, basically the same as the original route of the plane traffic without redundant bypass: It can make the two-way six-lane intersection straight lane motorway and the left turn vehicle motorized road without cross-passing, which solves the problem that the intersection of two roads is generated at the intersection Traffic jam, blocked traffic Pass the problem. This is a kind of road with no unnecessary bypass. At the intersection, the motor vehicle only has uphill and downhill slopes different from plane traffic, and the driving route is basically the same as the current driving route on the plane road with traffic lights, which does not change people's leveling. The driving directions and habits of crossroads will not be lost due to redundant bypass during the passage of the intersection. In addition, the construction of bridges or tunnels is less than any existing full-crossing overpasses or tunnels, saving bridge construction. cost.
五、 双向六车道的小十字路口可用: 本发明只用四个同向分叉 "卜"字形拱桥的组合, 或只用四个同向分叉 "卜"字形分叉隧道的组合, 就实现了十字路口无交叉占道冲突的完全 畅通,比现有绕行的全互通立交桥大量减少了桥或隧道的长度,大量减少了占地面积和空间, 使其在圆形直径只有 65米的城市双向六车道小面积十字路口也能实现立交畅通, 即没有交 叉占道冲突点, 也没有交织段, 为解决世界性的城市干道机动车交通拥堵问题提供了新的设 计方案。  5. Two-way six-lane small crossroads are available: The invention uses only a combination of four identical-direction bifurcated "b"-shaped arch bridges, or only four combinations of four-way bifurcation "b"-shaped bifurcation tunnels. At the crossroads, there is no cross-crossing conflict, and the total cross-overpass is less than the existing bypass. The length of the bridge or tunnel is greatly reduced, and the floor space and space are greatly reduced, making it a city with a circular diameter of only 65 meters. The two-way six-lane small-area intersection can also realize the smooth transition of the interchange, that is, there is no cross-occupation conflict point, and there is no interweaving section, which provides a new design solution for solving the problem of motor vehicle traffic congestion in the world's urban trunk roads.
六、 可还道于行人: 用四个同向分叉 "卜"字形拱桥组合成的两个双嵌入式组合桥用于 十字路口, 十字路口的地面可允许行人和非机动车随意通行, 没有机动车干扰。  6. Can be returned to pedestrians: Two double-embedded combination bridges composed of four identical bifurcation "B" shaped arch bridges are used for intersections. The ground at the intersection allows pedestrians and non-motor vehicles to pass freely. Motor vehicle interference.
七、 直行车辆与左转车辆的立体交通只用一层桥或隧道: 不论是直行车辆下穿对面的左 转弯桥, 还是左转弯车辆下穿左侧的直行桥和左转弯桥, 都只用一层立交桥。 对城市景观影 响更小。 不论是直行车辆上跨对面的左转弯隧道, 还是左转弯车辆上跨左侧的直行隧道和左 转弯隧道, 都只用一层隧道。 本发明的发明点是:  7. The three-dimensional traffic between a straight-through vehicle and a left-turning vehicle uses only one layer of bridge or tunnel: whether it is a left-turning bridge with a straight-through vehicle or a left-turning bridge and a left-turning bridge. A layer of overpass. It has less impact on the urban landscape. Whether it is a cross-overturned left-turn tunnel on a straight-through vehicle or a straight-through tunnel and a left-turn tunnel on the left-turning vehicle, only one tunnel is used. The invention of the present invention is:
一、 按十字路口地面支道的条数设相同个数、 基本相同结构、 互不连接的小型独立立 交桥或隧道:中国专利 200820230509.5的说明书附图所公开的网框形立交桥是连为一体的一 个整体大型立交桥, 把十字路口各种行车道的全部立体桥连接为一体。 而本发明认为, 来自 不同地面支道的立交桥在经过十字路口后, 不必要与来自其它地面支道的立交桥连接, 更能 实现与来自其它地面支道的立交桥的车辆合并车道, 驶离该十字路口, 还更不易堵车, 所以 本发明把来自不同地面支道的立交桥都不相互连接, 使十字路口的四条地面支道分别用四个 同向分叉 "卜"字形小型立交桥、 互不连接的组合成一个组合桥。 而且这种四个小型立交桥 的组合桥在防止地质变化、加宽了合并车道的长度等方面优于中国专利 200820230509.5的说 明书附图所公开的网框形立交桥。 也就是说: 从单个比较, 本发明把网框式立交桥拆分为四 个小型 "卜"字形立交桥; 从整体比较, 四个小型 "卜"字形立交桥的组合桥成占地面积小 的十字形, 而不是占地面积宽的网框形。  1. Set up the same number, the same structure, and the small independent overpass or tunnel that are not connected to each other according to the number of ground roads at the intersection: the frame-shaped overpass disclosed in the specification of Chinese Patent 200820230509.5 is a one-piece one. The overall large overpass connects all the three-dimensional bridges at various intersections at the intersection. However, the present invention considers that the overpasses from different ground supports do not need to be connected with overpasses from other ground supports after crossing the intersection, and can realize the merged lanes with the overpasses from other ground supports, and leave the crossroads. The mouth is also less prone to traffic jams. Therefore, the present invention does not connect the overpasses from different ground supports to each other, so that the four ground support passages at the intersection are respectively separated by four in-situ "b" shaped small overpasses, which are not connected to each other. Combine a combined bridge. Moreover, the combined bridge of the four small overpasses is superior to the frame-shaped overpass disclosed in the drawings of the Chinese Patent No. 200820230509.5 in terms of preventing geological changes and widening the length of the merged lane. That is to say: From a single comparison, the present invention splits the frame-type overpass into four small "b"-shaped overpasses; from the overall comparison, the composite bridge of four small "b"-shaped overpasses has a small cross-shaped shape. Instead of a wide mesh frame.
而本发明认为, 来自不同地面支道的隧道在经过十字路口后, 不必要与来自其它地面 支道的隧道连接, 更能实现与来自其它地面支道的隧道的车辆合并车道, 驶离该十字路口, 还更不易堵车, 所以本发明把来自不同地面支道的隧道都不相互连接, 也包括经过十字路口 后不相互连接, 使十字路口的四条地面支道分别用四个同向分叉 " 卜"字形叉小型隧道、 互不连接的组合成一个组合隧道。 而且这种四个小型隧道的组合隧道在防止地质变化、 加宽 了合并车道的长度等方面优于中国专利 200820230509.5《直接左、 右转互通立交桥》 的说明 书附图所公开的网框形立交桥。 也就是说: 从单个比较, 本发明把网框式立交桥拆分为四个 小型 "卜"字形隧道; 从整体比较, 四个小型 "卜"字形隧道的组合隧道成占地面积小的十 字形, 而不是占地面积宽的网框形。 However, the present invention considers that tunnels from different ground supports are not necessarily from other grounds after passing through the intersection. The tunnel connection of the branch road can realize the merger of the vehicles with the tunnels from other ground support roads, and the traffic from the intersections is also less likely to be jammed. Therefore, the present invention does not connect the tunnels from different ground supports to each other. Including the intersections after crossing the intersection, the four ground supports of the intersection are respectively combined into a combined tunnel by four small tunnels with the same direction bifurcated "b" shaped forks. Moreover, the combined tunnel of the four small tunnels is superior to the frame-shaped overpass disclosed in the specification of the Chinese Patent No. 200820230509.5 "Direct Left and Right Turnover Interchange" in preventing geological changes and widening the length of the merged lane. That is to say: From a single comparison, the invention splits the frame-type overpass into four small "b" shaped tunnels; from the overall comparison, the combined tunnel of four small "b" shaped tunnels has a small cross-shaped shape. Instead of a wide mesh frame.
二、 直行桥和左转弯桥的桥体不相互穿越: 这种直行桥不穿过、 不跨过对面的左转弯 桥, 就使直行桥上的车辆从地面穿过对面的左转弯桥实现直行; 并且左转弯桥不穿过、 不跨 过左侧同向分叉 "卜"字形叉桥的直行桥和左转弯桥, 使左转弯桥上的车辆从地面穿过左 侧同向分叉 "卜"字形叉桥的直行桥和左转弯桥。 这种结构使不同的同向分叉 "卜"字形 叉桥上的直行车辆和左转车辆能在地面实现合并车道, 只要在地面合并车道就可以有较长距 离的合并车道区段, 不易因合并车道太小太窄而堵车, 克服了中国专利 200820230509.5的说 明书附图所公开的网框形立交桥在立交桥上合并车道只有一个合并车道位点而易产生堵车 的问题。  2. The bridges of the straight and left turns bridges do not cross each other: the straight bridge does not pass through and does not cross the opposite left turn bridge, so that the vehicles on the straight bridge pass straight through the opposite left turn bridge. And the left-turning bridge does not pass through, does not cross the left-hand bifurcation of the "b"-shaped fork bridge of the straight-line bridge and the left-turning bridge, so that the vehicle on the left-turning bridge crosses the left side of the same direction from the ground"卜" The straight bridge and the left turn bridge of the forked bridge. This structure enables the straight-line vehicles and the left-turning vehicles on the different bidirectional forks of the "B"-shaped fork bridge to realize the merged lane on the ground. As long as the lanes are merged on the ground, there can be a combined lane section with a longer distance. The merged lane is too small and too narrow and the traffic jam is overcome. The frame-shaped overpass disclosed in the drawings of the Chinese patent 200820230509.5 overcomes the problem that the merged lane on the overpass has only one merged lane and is prone to traffic jam.
直行隧道和左转弯隧道的隧道不相互穿越: 这种直行隧道不跨穿过对面的左转弯隧道, 就使直行隧道内的车辆从地面跨过对面的左转弯隧道实现直行; 并且左转弯隧道不跨穿过左 侧同向分叉 "卜"字形叉隧道的直行隧道和左转弯隧道, 使左转弯隧道内的车辆从地面跨过 左侧同向分叉 "卜 "字形叉隧道的直行隧道和左转弯隧道。这种结构使不同的同向分叉 "卜 " 字形叉隧道内的直行车辆和左转车辆能在地面实现合并车道, 只要在地面合并车道就可以有 较长距离的合并车道区段, 不易因合并车道太小太窄而堵车。  The tunnels of the straight tunnel and the left turn tunnel do not cross each other: this straight tunnel does not cross the opposite left turn tunnel, so that the vehicles in the straight tunnel pass straight across the opposite left turn tunnel from the ground; and the left turn tunnel does not A straight tunnel and a left turn tunnel that cross the left side of the same direction and split the "B" shaped fork tunnel, so that the vehicle in the left turn tunnel crosses the left side of the tunnel and the straight tunnel of the "B" shaped fork tunnel Turn left into the tunnel. This structure enables different straight-forward and left-turn vehicles in the same-direction bifurcated "b"-shaped fork tunnel to realize the merged lane on the ground. As long as the lane is merged on the ground, there can be a combined lane section with a longer distance. The merged driveway is too small and too narrow and traffic jams.
三、 把交通冲突点移到远离十字路口的支道位置去立体交通: 本发明不是在平面交通 状态发生交叉占道冲突的位置, 即不在十字路口范围内的位置, 解决来自不同地面支道的直 行车道和左转弯车道, 以及左转弯车道之间的交叉占道冲突, 而是创造性的把这两类交通冲 突点移到远离十字路口的四条地面支道上立体交通解决交通冲突, 从而能最少地占用十字路 口的地面和空间。 本畅通结构对十字路口的环形区域地面面积要求大大降低。 只要地面支道 的建筑物之间有八车道宽度, 和十字路口直径 65米以上的地面和空间就能建成本发明的组 合畅通桥或隧道, 实现旧城六车道的十字路口交通畅通, 对于解决旧城区小十字路口交通堵 塞有开创性的意义。 四、 在两对面的地面支道上, 直行桥的地面延长车道下穿对面的左转弯桥: 相对直行 即相反方向直行的两个双向直行拱桥, 相互独立、 不共用一个桥; 即直桥接地端比对面同向 分叉 "卜"字形叉桥的共同起桥接地端更接近两个分组桥的两组直行拱桥的立体十字交叉中 心; 直桥接地端在接近对面同向分叉 "卜"字形叉桥的高位置区域或在此之前接地, 这样直 桥接地端留出了对面同向分叉 "卜"字形叉桥的高位置区段左侧空间, 让对面的左弯桥单行 段可以直接在左转弯一侧与对面的直行拱桥分叉, 两桥分叉使左转弯车辆可直接左转弯而不 需要多余的绕行, 又能使离开直桥接地端的车辆能从相对面左转弯桥的分叉段下方地面穿 过, 实现直行车辆与对面左转弯车辆的立体交通。 3. Move the traffic conflict point to the branch road away from the intersection to the three-dimensional traffic: The present invention is not in the position where the plane traffic state crosses the road collision, that is, the position within the intersection, and solves the problem from different ground support Straight lanes and left turn lanes, as well as cross-track conflicts between left-turn lanes, but creatively move these two types of traffic conflict points to three ground-moving roads away from the intersection to solve traffic conflicts, thus minimizing Take up the ground and space at the intersection. The smooth connection structure of the circular area of the intersection is greatly reduced. As long as there are eight lanes between the buildings on the ground branch, and the ground and space with a diameter of 65 meters or more at the intersection, the combined bridge or tunnel of the invention can be built to realize the smooth traffic at the intersection of the six lanes of the old city. Traffic jams at small crossroads in the old city are groundbreaking. 4. On the two opposite ground support roads, the ground extension lane of the straight bridge crosses the opposite left turn bridge: two straight bi-directional straight arch bridges that are relatively straight and opposite straight, independent of each other, do not share a bridge; that is, the straight bridge ground The common bridge grounding end of the opposite-direction bifurcation "B"-shaped fork bridge is closer to the three-dimensional cross center of the two sets of straight arch bridges of the two group bridges; the straight bridge ground end is close to the opposite direction of the bifurcation "b" shape The high-position area of the fork bridge is grounded before this, so that the grounding end of the straight bridge leaves the space on the left side of the high-position section of the opposite-direction bifurcated fork-shaped fork bridge, so that the opposite left-handed bridge can be directly On the left turn side and the opposite straight arch bridge, the two bridge forks enable the left turn vehicle to turn left without any unnecessary bypass, and the vehicle leaving the ground end of the straight bridge can turn from the opposite side to the left side of the bridge. The ground below the bifurcation section passes through to realize the three-dimensional traffic of the straight-through vehicle and the opposite left-turning vehicle.
在两对面的地面支道上, 直行隧道的地面延长车道跨过对面的左转弯隧道: 相对直行 即相反方向直行的两个双向直行隧道, 相互独立、 不共用一个隧道; 即直隧道接地端比对面 同向分叉 "卜"字形叉隧道的共同进隧道接地端更接近两个分组隧道的两组直行隧道的立体 十字交叉中心; 直隧道接地端在接近对面同向分叉 "卜"字形叉隧道的深位置区域接地, 这 样直隧道接地端留出了对面同向分叉 "卜"字形叉隧道的深位置区段左侧空间, 让对面的左 弯隧道单行段可以直接在左转弯一侧与对面的直行隧道分叉, 两隧道分叉使左转弯车辆可直 接左转弯而不需要多余的绕行, 又能使离开直隧道接地端的车辆能从相对面左转弯隧道的分 叉段上方地面跨过, 实现直行车辆与对面左转弯车辆的立体交通。  On the two opposite ground support roads, the ground extension lane of the straight tunnel crosses the opposite left turn tunnel: two straight two-way straight tunnels that are relatively straight and opposite in direction, independent of each other, do not share one tunnel; that is, the straight tunnel ground end is opposite The grounding end of the common tunnel of the same-forward bifurcation "b"-shaped fork tunnel is closer to the three-dimensional cross-over center of two sets of straight tunnels of two group tunnels; the grounding end of the straight tunnel is close to the opposite side of the bifurcation "b"-shaped cross-section tunnel The deep position area is grounded, so that the straight tunnel ground end leaves the left side space of the deep position section of the opposite-direction bifurcated "b"-shaped fork tunnel, so that the opposite left-turn tunnel single-line section can be directly on the left turn side The opposite straight tunnel is bifurcated, and the two tunnels are forked so that the left-turning vehicle can directly turn left without unnecessary bypass, and the vehicle leaving the ground of the straight tunnel can turn from the opposite side to the left side of the branching section of the tunnel. Through, the three-dimensional traffic of the straight-through vehicle and the opposite left-turning vehicle is realized.
五、 左转弯桥的地面延长车道下穿左侧地面支道的直行桥和左转弯桥: 左弯桥单行段 按左转弯方向直接到达左侧的同向分叉 " 卜"字形叉桥的高位置区域附近接地, 其地面延 长车道与该高位置区域的同向分叉 " 卜"字形叉桥立体交通, 就解决了左转弯车辆与左转 弯要到达的地面支道的直行车和左转弯车的交叉占道冲突问题。 左转弯车辆不绕行, 减少了 不必要的交通冲突点。  5. The ground extension lane of the left turn bridge passes through the straight bridge and the left turn bridge of the left ground support road: the single section of the left curved bridge directly reaches the left side of the same direction bifurcation "b" shaped fork bridge according to the left turn direction The grounding area near the location area, the ground-extended lane and the high-position area of the same-direction bifurcation "Bu"-shaped fork bridge three-dimensional traffic, solve the left-turn and left-turn vehicles of the left-turning vehicle and the left-hand turn to reach the ground branch The cross-occupation conflict problem. Left-turn vehicles do not bypass, reducing unnecessary traffic conflict points.
左转弯隧道的地面延长车道跨过左侧地面支道的直行隧道和左转弯隧道: 左弯隧道单 行段按左转弯方向直接到达左侧的同向分叉 "卜"字形叉隧道的深位置区域附近接地面, 其地面延长车道与该深位置区域的同向分叉 "卜"字形叉隧道立体交通, 就解决了左转弯 车辆与左转弯要到达的地面支道的直行车和左转弯车的交叉占道冲突问题。左转弯车辆不绕 行, 减少了不必要的交通冲突点。  The left-turn tunnel of the left-turn tunnel crosses the straight tunnel and the left-turn tunnel of the left ground support road: The single-row section of the left-turn tunnel directly reaches the deep position area of the same-direction bifurcation "Bu"-shaped fork tunnel on the left side in the direction of the left turn. The nearby grounding surface, the ground-extended lane and the deep-direction cross-section of the "B"-shaped cross-shaped tunnel in the deep position area solve the straight-through and left-turning vehicles of the left-turning vehicle and the left-hand turn to reach the ground branch. Cross-occupation conflicts. Left-turn vehicles do not bypass, reducing unnecessary traffic conflict points.
六、把左转弯桥设计成左、右转弯两用桥:把左转弯桥不穿过不跨过左侧同向分叉 "卜" 字形叉桥, 并且左转桥接地端与左侧地面支道的右转车道连通, 左转弯桥就成为左、 右转弯 两用桥。 而不需要两个桥分别作为左、 右转弯使用。  Sixth, the left turn bridge is designed as a left and right turn dual-purpose bridge: the left turn bridge does not pass through the left side of the same direction bifurcation "Bu" shaped fork bridge, and the left turn bridge ground end and the left ground support The right turn lane of the road is connected, and the left turn bridge becomes a left and right turn bridge. There is no need for two bridges to be used as left and right turns respectively.
把左转弯隧道设计成左、 右转弯两用隧道: 把左转弯隧道不穿过不跨过左侧同向分叉 "卜"字形叉隧道, 并且左转隧道接地端与左侧地面支道的右转车道连通, 左转弯隧道就成 为左、 右转弯两用隧道。 而不需要两个隧道分别作为左、 右转弯使用。 Design the left turn tunnel into a left and right turn tunnel: Turn the left turn tunnel without crossing the left side of the same direction The "b"-shaped fork tunnel, and the grounding end of the left-turn tunnel is connected with the right-turn lane of the left ground support, and the left-turn tunnel becomes a left-and-right turn tunnel. There is no need for two tunnels to be used as left and right turns respectively.
七、 同一个分组桥中, 直桥单行段伸入到对面同向分叉 "卜"字形叉桥的分叉口中: 两个分叉口相对的同向分叉 "卜"字形叉桥组成一个分组桥, 该分组桥位于相对直行的两条 地面支道上。 两个同向分叉 "卜"字形叉桥相互独立不相连接, 但它们直桥单行段伸入到对 面同向分叉 "卜"字形叉桥的分叉口中, 成两个双嵌入式分组桥。 两个分组桥的两组直桥 单行段在十字路口中心区域为两层桥体的立体交通。就可以将十字路口中心区域地面还道于 行人和非机动车, 实现更人性化的交通行式。  7. In the same group bridge, the straight section of the straight bridge extends into the bifurcation of the opposite bifurcation of the "b"-shaped fork bridge: the two bifurcations are opposite to each other. A group bridge, which is located on two ground legs that are relatively straight. Two two-way bifurcated "b"-shaped fork bridges are independent of each other, but their straight-bridge single-row segments extend into the bifurcation of the opposite-direction bifurcated "b"-shaped fork bridge into two double-embedded groups. bridge. Two sets of straight bridges of two group bridges The single line section of the two sections is a three-dimensional traffic of the two-story bridge in the central area of the intersection.
