Problems solved by technology

[0003] In recent years, many overpasses have been built at the crossroads. Because the current overpasses run east-west and north-south, and the left and right turns are radial outside the disc, the area is large. Due to the restrictions of the original planned roads , it is not enough to build a new fully interchangeable overpass, and it is difficult to demolish shops, residences, and house buildings at intersections. During rush hour, there are still parking waiting phenomena, and even traffic jams occur from time to time

Embodiment 1

[0068] According to Figure 1 and Figure 2, the first floor represents the motor vehicle lanes, East E, West W, South S, North N, right-turn lanes and U-turn lanes, and east (E↑) west (W↑) directions are arranged in a straight line. Level, four right-turning lanes in the east, west, south and north of the non-motor vehicle lane.

[0069] Second and third floors The north-south through lanes S↑ and N↑ are arranged on the second floor. North-south direction turn left S L , N L It is an S-shaped lane, turn left in advance and slowly rotate from the second floor to the third floor. A temporary parking lot will be built in the middle space to facilitate congestion relief. Turn left in the east-west direction and use E L and W L It means that it rises slowly by three meters from the third floor to the central area and then descends to the south and north of the second floor.

Embodiment 2

[0071] According to Fig. 3 and Fig. 4, the first layer represents non-motor vehicle and motor vehicle lane east (E R ), West (W R ), South (S R ), North (N R ), the straight lanes for motor vehicles, and the east (E) and west (W) straight lanes are arranged on the first floor.

[0072] East (E L ), West (W L ) turn left, arranged on the first floor as shown in the figure, go straight through the center point and make a left turn under the opposite bridge, after exiting the bridge, turn right on the opposite side, and ascend from the first floor to the second floor.

[0073] The north-south straight roads on the second and third floors are arranged on the second floor (S, N) 2

[0074] Turn left in the north-south direction (s L , n L ) 2 3 It is an S-shaped lane, turn left in advance and slowly rotate from the second floor to the third floor. A temporary parking lot will be built in the middle space to facilitate congestion relief.

Embodiment 3

[0077] As shown in Figure 5, the lanes on the first floor are arranged with south (S) and north (N) through lanes, and south to right turns (S R ) and turn east to the right (E R ) and three non-motorized lanes as shown in the figure

[0078] Turn left east (E L ) is arranged to turn left in the east to a Hongqiao in the south, with a total length of 300m and an elevation of +6.5 in the middle 100m.

[0079] Turn north to the left (N L ) is arranged to go straight from north to south, pass through the central point, enter the south bridge, turn left and exit the bridge, then turn into a south-right turn system, slowly rise along the Hongqiao, and drive side by side with the east-turn left Hongqiao, as shown in the figure.

Abstract

A tower type rotating and complete interchanging overpass comprises riding roads in four major directions, with the left and right turning road remaining in the tower type circle under the third floor or even lower. It can achieve the smooth running of vehicles passing the crossroad, with small land occupation, quick traffic jam alleviation ability with two sets of functions. On the second and third floor, there are four direct passages and four left turning systems, free from traffic lights with high speed running. Traffic lights can be applied to the first floor going in all directions. A crossroad has the function of two crossroads, with the troley bus arranged at the first floor without being interrupted. Most important of all, it can control the noise of vehicle, being environment friendly and low in cost.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a tower-type rotating fully intercommunicating overpass. Background technique [0002] Most of the main roads in large and medium-sized cities in my country were planned and constructed before the 1990s, with a road width of about 60 meters. Due to the rapid development of my country's socialist economic construction, motor vehicles have increased significantly. In recent years, the traffic roads in various places have been congested to varying degrees, and the congestion at intersections is even more serious. [0003] In recent years, many overpasses have been built at the crossroads. Because the current overpasses run east-west and north-south, and the left and right turns are radial outside the disc, the area is large. Due to the restrictions of the original planned roads , it is not enough to build a new fully interchangeable overpass, and it is difficult to demo...
