Staggered cross intersection interchange structure

Abstract

The invention discloses a staggered cross intersection interchange structure. The staggered cross intersection interchange structure comprises a transverse road, a first longitudinal road, a second longitudinal road, a first ramp and a second ramp. The first longitudinal road and the second longitudinal road intersect with the transverse road to form a staggered intersection. The first ramp and the second ramp are each a one-way interchange or a one-way tunnel, the planar projections of the first ramp and the second ramp do not intersect and only occupy part of lanes. The first ramp is connected with the first longitudinal road and the transverse road. The second ramp is connected with the second longitudinal road and the transverse road. Exits of the first ramp and the second ramp are both located in the staggered intersection, and turn-round openings are formed at entrances of the first ramp and the second ramp correspondingly. According to the staggered cross intersection interchange structure, the clearance or stratum requirements are reduced, and an interchange bridge or a tunnel structure is determined according to the actual situation; the traffic interchange problems of thestaggered oblique-crossing cross intersection can be well solved, and small-angle turning points and large confluence points are reduced; and the staggered cross intersection interchange structure isused in the field of road reconstruction.

Description

technical field [0001] The invention relates to the field of road reconstruction, in particular to a dislocation intersection interchange structure. Background technique [0002] With the rapid development of the city, the urban traffic volume has increased rapidly. There are many misplaced intersections in the urban roads of our country, which is caused by the land use restriction of the urban road traffic planning. If the planned roads on both sides of the opened road are regarded as an independent road, the two independent planned roads and the opened road form a T-shaped intersection respectively. At the same time, in many cases, due to the time difference in planning, the intersection angles of the roads at intersections in urban roads are not orthogonal or close to orthogonal. Compared with the orthogonal intersection, there is an oblique intersection with a smaller intersection angle. When there is dislocation at the same time, it becomes a dislocation oblique inte...

Problems solved by technology

[0003] Setting up light control at two T-shaped intersections will have a greater impact on the roads that have been opened to traffic. The main impact is that after the planned road is built, the straight traffic will increase the waiting control time twice.

Even when there is already a light control near the oblique intersection, then the two T-shaped intersections cannot be equipped with light control, because the distance between the light control is too close, which will seriously affect the traffic.

At the same time, there is basically no possibility of expanding the land use range of urban roads. Generally, bridges or tunnels along the longitudinal direction of the road are set within the road range, and there is no condition for turning ramps.

Ordinary overpasses or tunnel structures are directly connected to the planned roads on both sides of the roads that have been opened to traffic, but the settings of bridges or tunnels with two-way lanes are seriously affected by the surrounding existing building facilities. Some locations do not provide the required clearance or ground

For example, if there are lower expressways above or underground subway facilities, detours or further renovations will increase the cost of construction renovations and affect the quality of construction renovations

Moreover, setting a two-way interchange or tunnel directly between the two planned roads can only achieve straight travel on inclined roads, and cannot achieve full intercommunication at dislocated intersections.
