A south-north lane straight movement and U-turn road is located on a tunnel of the second floor underground; an east-west lane straight movement and U-turn road is located on a passage of the first floor underground, and four right-turning lanes are also located on the passage of the first floor underground; four non-motorized vehicle lanes in the east, west, south and north converge at a non-motorized vehicle interchange ground courtyard square (45) which is a half storey high, and distribute non-motorized vehicles in four directions including the east, the west, the north and the south respectively by means of the non-motorized vehicle interchange ground courtyard square (45). Left-turning lanes in the four directions are formed by means of viaducts. The viaducts and the ground non-motorized vehicle lanes are fixed in position, and vehicles on other layers can arbitrarily move up and down under the viaducts. The present invention can be applied to urban trunk roads, and intersections with high traffic efficiency requirements.

Description

Urban trunk intensive overpass Technical field

The invention relates to the technical field of highway overpasses, in particular to an interchangeable urban interchange road or an interchangeable overpass bridge shared by a motor vehicle and a non-motor vehicle with heavy traffic pressure.

Background technique

At present, the interchange bridge is mainly composed of four-ring and four-arc-shaped lobes, which has the advantages of fast traffic speed, the same shortcomings are also obvious, and the floor space is large, especially in the area around the intersection of roads. There is a large amount of idle land inside the ring and between the ring and the arc. This is inconsistent with the intensive requirements of urban road construction land, and it is impossible to realize the road layout in the urban road reconstruction. Moving or dismantling the construction of structures around the intersection to obtain a square land will greatly increase the cost of the construction of the demolition and construction, and may ultimately be worth the loss. Also, more importantly, this kind of overpass cannot meet the communication requirements of non-motor vehicles and motor vehicles.

In order to solve the above technical problems, the present invention provides an interchangeable urban trunk road intensive type overpass.

The second floor of the overpass of the north-south straight-through and turn-over road includes Figure 2:

The north-south straight road 2 and the north-south straight road 3 arranged in the direction of the overpass are arranged directly through the underground tunnel of the overpass to enter the north-south straight road 32 and the north-south straight road 33 away from the overpass. . The north-to-north straight road 12 and the south-to-north straight road 13 entering the overpass direction can directly enter the south-north straight road 22 and the south-north straight road 23 to leave the overpass through the underground tunnel of the overpass. When entering the center of the overpass, the north-south straight road 2 can be turned northward along the central square on the second floor of the overpass to enter the south-north straight road 22 and leave the overpass. When entering the center of the overpass, the north-to-north straight road 12 can be turned southward along the central square of the second floor of the overpass to enter the north-south straight road 32 and leave the overpass, thus achieving the smallest distance to turn around and over the overpass to meet the urban road. Pass the rules of changing direction at will.

The east-west direction two-way four-lane straight-forward and turn-over road is located on the basement level as shown in Figure 3:

The westward east straight road in the direction of entering the overpass in part of Figure 3: 7. The westward east straight road 8 can directly enter the westbound east straight road 37 and the westward east straight road 38 in the direction of the overpass from the underground tunnel of the overpass. From the overpass. The eastbound west straight road 17 and the eastbound west straight road 18 entering the overpass direction can directly enter the eastbound west straight road 27 and the eastbound west straight road 28 away from the overpass in the direction of the overpass. Further westward east straight road 7 when entering the center of the overpass can be turned westward along the central square of the basement of the overpass to enter the eastbound west straight road 27 and leave the overpass. East to west straight road 17 When entering the center of the overpass, you can turn eastward and enter the westbound east straight road 37 to leave the overpass along the central square of the basement of the overpass, thus achieving the smallest distance to turn over the overpass and meet the urban road. Pass the rules of changing direction at will.

Further, at the same time, four right-turning lanes that turn right in the north, south, east and west directions into the north and south east and west are also located on the underground floor as shown in Figure 3:

The other part of Figure 3 is arranged to enter the overpass direction of the east-to-north turn and east-to-west straight driveway 19. You can either go straight along the lane 19 and enter the eastbound west straight road 29 of the overpass to leave the overpass or enter When crossing the overpass, turn right and turn north on the straight road 24 from the south to north of the overpass. Enter the overpass direction of the southbound east right turn lane 14 After entering the overpass, turn right into the westbound east straight road 39 in the direction of the overpass and drive away from the overpass to realize the right turn of the vehicle. The west-to-south right turn and the west-to-east straight driveway 9 entering the overpass direction can either go straight along the lane 9 and enter the westbound east straight road 39 off the overpass to leave the overpass, or go straight north and south along the overpass when entering the overpass Road 34 turns right and heads south to the overpass. Enter the overpass direction of the north to west right turn lane 4 After entering the overpass, turn right into the eastbound west straight road 29 in the direction of the overpass and leave the overpass to realize the right turn of the vehicle.

Further, if the underground two-story tunnel is interchanged with the underground one-floor tunnel, the right-turn lanes are arranged on the basement level and the tunnel in the north-south direction. The right-turn lane in the north-south direction has straight through. The function of the bridge, while the right turn direction in the east-west direction, only the right turn function remains.

Further, FIG. 4 shows a ground non-motor vehicle road layout diagram of the present invention. Since the non-motor vehicle has a slow vehicle speed, low traffic height requirement, low power, and high safety, it meets at the ground floor of the overpass and passes through the ground of the overpass. The patio is guided for diversion.

Non-motor vehicles enter the viaduct from the north to south straight road 5, west to east straight road 10, south to north straight road 15, east to west straight road 20 into the ground floor of the overpass, and choose to enter on the ground floor of the overpass. Drive away from the southbound north straight road 25, the eastbound west straight road 30, the northbound south straight road 35, and the westbound east straight road 40 away from the overpass. The overpass of the non-motor vehicle is realized.

Further, FIG. 5 shows a left turn lane layout of the present invention, and all left turn lanes in the present invention are composed of an upper elevated approach bridge, an viaduct and a lower elevated approach bridge.

The northward east left turn lane 1 has a raised road to a 5 meter high approach bridge and is connected to the viaduct 41. At the end of the viaduct 41, it is connected to the lower elevated approach bridge of the westward east straight road 36 which is driven away from the overpass to realize the northward eastward travel of the vehicle.

The west-to-north left turn lane 6 has a raised road to a 5 meter high approach bridge connected to the viaduct 42 and is connected at the end of the viaduct 42 to the lower elevated approach bridge of the southbound north straight road 21 that exits the overpass to achieve west-to-north travel of the vehicle.

The southward west left turn lane 11 has a raised road to a 5 meter high approach bridge connected to the viaduct 43 and is connected at the end of the viaduct 43 to the lower elevated approach bridge leading away from the eastbound west straight road 26 of the overpass to achieve south-west travel of the vehicle. .
