Problems solved by technology
[0003] The present invention is in order to solve the above-mentioned deficiencies in the prior art, and proposes a coupled overpass road structure with two short-distance intersections, in order to enable linkage and coupling of two short-distance intersection overpasses, and without setting up In the case of traffic lights, it solves the problem that the existing two short-distance intersection overpasses cannot realize full intercommunication of all its imports and exports, thereby effectively alleviating the high-load traffic pressure on the main road, improving the traffic efficiency of vehicles, and serving the growing regional traffic system

Embodiment Construction
[0042] In this embodiment, the overall structure of a coupling type overpass road of a short-distance double intersection is as follows: figure 1As shown, it is a new type of overpass road formed by the coupling of two short-distance four-fork intersection overpasses. part.
[0043] Among them, the main intersection road Ⅰ and the auxiliary intersection road Ⅱ are traversed by the east-west main road A, which is composed of two-way six-lane roads that go down from the ground floor to the underground tunnel and then go up to the ground floor. figure 2 As shown, it specifically includes: the first one-way street A1 from east to west and the second one-way street A2 from west to east; the first one-way street A1 from east to west includes the first entrance road T1 and the first exit road R1; the first entrance road Road T1 is composed of the first inner through lane 1, the first middle through lane 2 and the first right-left turn lane 3; the first inner through lane 1 and the ...

The invention discloses a short-distance double-intersection coupled overpass road structure which comprises a main intersection road, an auxiliary intersection road and a coupled road; the main intersection road is formed by right-angled intersection of a right side road of a trunk road in an east-west direction and a trunk road in a north-south direction, and the auxiliary intersection road is formed by right-angled intersection of a left side road of the trunk road in the east-west direction and a branch road in the north-south direction, i.e., the trunk road in the east-west direction transversely runs through the main intersection road and the auxiliary intersection road; the coupled road effectively connects the main intersection road and the auxiliary intersection road so as to form the integral short-distance double-intersection coupled overpass road structure. The short-distance double-intersection coupled overpass road structure disclosed by the invention can be used to solve the problem that an existing short-distance overpass cannot implement complete interconnection of six entrances, ensure that smooth operation of the traffic is still kept in a case of not arranging traffic signal lights, and relieve traffic pressure of a large-load road, thus effectively solving the problems to realize urban traffic safety and avoid traffic congestion.
Description
technical field [0001] The invention belongs to the field of road and bridge design, in particular to a coupled overpass road structure with short-distance double intersections. Background technique [0002] A road intersection is a part where roads in different directions intersect at the same level, and is usually divided into level intersections and level intersections. The three-dimensional intersection can make the traffic flow in all directions pass on different planes, and overcome the characteristics of low speed and poor traffic capacity of the plane intersection. The full name of the overpass is "three-dimensional crossover bridge". It is a modern land bridge built at the intersection of two crossing roads with upper and lower layers and multi-directional non-interference. In today's urban roads, there are a large number of short-distance overpass intersections. The distance between two overpass intersections is generally within 500m, and there are many overpass i...
