Abstract

An interchange includes main lanes (1), left turn ramps (2) and right turn ramps (3). Each main lane (1) comprises an initial section (4), a right turn section (5), a crossing section (6) and a final section (7), which are connected in sequence; the initial section (4) of each main lane (1) merges together with the final section (7) of an opposite main lane (1); the cross section (6) of each main lane (1) bridges the main lane (1) on its left and passes under the cross section (6) of the main lane (1) on its right. The left turn ramp (2) of each main lane (1) is connected with the inner side of the main lane (1) at the cross section (6) of the main lane on its right, and connected to the outer side of the main lane (1) on its right; and the outer side of the right turn ramp (3) is connected between an initial section (4) and a final section (7) of two adjacent main lanes (1). The interchange has the advantages of small land occupation, reasonable structure, beautiful and decent appearance, and is applicable to municipal cross traffic intersections.

Description

A kind of interchange viaduct

Technical field

The present invention relates to overpass bridge, be specifically related to a kind of interchange viaduct being applicable to the reduced building area of the cross traffic intersection in city.

Background technology

Overpass bridge, full name " cloverleaf intersection " is the upper lower leaf that important traffic joint is set up in city, multi-direction traveling, mutual modernization landbridge of not interfering with or disturb each other.The cross traffic intersection that wagon flow is large builds overpass bridge, effectively can alleviate the situation of traffic anxiety.Interchange viaduct can adopt double-layer structure, but often floor space is large.There is the mutually overlapping section of road in overpass bridge, the road surface near overlapping place has comparatively macrorelief, that is, there is comparatively macrodome.The overpass bridge floor space of homogeneous structure is less domatic steeper, domaticly too suddenly certain procedures will affect traffic safety, particularly in the winter of northern China most area, can cause larger potential safety hazard.For the section, urban district of an inch of land is an inch of gold, the construction of overpass bridge will solve can reduce floor space as far as possible, make the bridge floor gradient remain on zone of reasonableness again and ensure this contradiction of driving safety.

Summary of the invention

Technical problem to be solved by this invention is: for the problems referred to above, provide a kind of be applicable to the cross traffic intersection in city both can reduce floor space, the bridge floor gradient can be made again to remain on the overpass bridge of zone of reasonableness.

Technical solution of the present invention is: a kind of interchange viaduct, pontic comprises east, west, south, north four-way A-road, four left rotaring ring roads and four right-hand rotation ring roads, described in every bar, A-road is by initial segment, right-hand rotation section, the "the" shape track that Crossover phase and final stage are connected in turn, the initial segment of every bar A-road and the final stage of subtend A-road combine, pass by under the Crossover phase of its dextrad A-road after the Crossover phase of every bar A-road crosses over its left-hand A-road, near the Crossover phase being connected to its dextrad A-road inside the described left rotaring ring road of every bar A-road and A-road, and be connected with outside this dextrad A-road, be connected to outside described right-hand rotation ring road adjacent two A-roads initial segment and between final stage.

Technique effect of the present invention is: it has, and floor space is little, rational in infrastructure, have attractive appearance generous advantage, is applicable to the cross traffic intersection in city.Guaranteeing, under the prerequisite that the bridge floor gradient can remain within the scope of safe and reasonable, the floor space of pontic can be made less.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Detailed description of the invention

As shown in Figure 1, a kind of interchange viaduct, pontic comprises east, west, south, north four-way A-road 1, four left rotaring ring roads 2 and four right-hand rotation ring roads 3, it is characterized in that, A-road 1 described in every bar is by initial segment 4, right-hand rotation section 5, the "the" shape track that Crossover phase 6 and final stage 7 are connected in turn, the initial segment 4 of every bar A-road 1 merges with the final stage 7 of subtend A-road 1 together with (walking abreast), passed for 6 times by the Crossover phase of its dextrad A-road 1 after the Crossover phase 6 of every bar A-road 1 crosses over its left-hand A-road 1, near the Crossover phase 6 being connected to its dextrad A-road inside the left rotaring ring road 2 of every bar A-road 1 and A-road 1, and be connected with outside this dextrad A-road 1 (also can consider to merge or parallel join with the right-hand rotation ring road 3 of subtend A-road 1), be connected between the initial segment 4 of A-road 1 and the final stage 7 of its left-hand A-road 1 outside the right-hand rotation ring road 3 of every bar A-road 1.Right-hand rotation ring road 3 surrounds rhombus.

Described A-road 1 surrounds square structure in the center of overpass bridge by Crossover phase 6 is interlaced.

Described left rotaring ring road 2 is located at the periphery of described square structure, and left rotaring ring road 2 surrounds annular or petal.

Every bar A-road 1 misplaces in opposite directions with subtend A-road 1, and surround square between A-road 1 in center, left rotaring ring road 2 is trapped among square periphery and is incorporated to dextrad A-road 1, and right-hand rotation ring road 3 is located at outermost, assumes diamond in shape.The square length of side that the bridge floor gradient before and after Crossover phase 6 is surrounded by A-road 1 limits, and the bridge floor gradient can be limited in rational scope by the square length of side of proper extension.The present invention is applicable to the cross traffic intersection in city, when guaranteeing that the bridge floor gradient is suitable, the floor space of pontic can be made minimum in similar overpass bridge.

Claims
