Abstract

The utility model discloses a complete interchange, which comprises an east west ground artery, a south north elevated artery and four intersections. Each intersection has five traffic lanes and a left right change overpass. A west south curve, an east south curve and a south east curve are ground roads. A north south straightway is connected with the east traffic lane of the south north elevated artery through an approach bridge. A south north straightway spans the north south straightway through the left right change overpass and then is connected with the west traffic lane of the south north elevated artery and is connected with a south west curve through the south north elevated artery. A north intersection traffic lane is antisymmetrical to a south intersection traffic lane. An east intersection traffic lane is similar to the south intersection traffic lane but the straightway is connected with the east west ground artery. A west intersection traffic lane is antisymmetrical to the east intersection traffic lane. The utility model realizes that the drivers drive on the right when turning right and drive on the left when turning left. The vehicles turning left are as natural, smooth and quick as the vehicles turning right. The area of occupied floor is small and the building is low.

Description

A kind of complete interchange viaduct

Technical field

The utility model relates to a kind of highway interchange viaduct, particularly a kind of complete interchange viaduct.

Background technology

Complete interchange viaduct is the overpass bridge of instigating all roads of intersecting at the crossing to communicate with each other.All roads that need intersect are all realized the three-dimensional intersection by different elevations.Communication between the different elevation roads realizes by ad hoc ring road, makes any vehicle that enters the intersection can realize, turn right and keep straight on, and each is unblocked to wagon flow, does not disturb mutually, has eliminated the plane conflict point fully.Therefore, complete interchange viaduct is the most perfect up to now a kind of overpass bridge form.Illustrated in figures 1 and 2 is two kinds of canonical forms of complete interchange viaduct.Wherein first kind is the individual layer intersection.The overpass bridge of these forms has all solved the collision problem between the different directions vehicle of intersection preferably.But the major defect of overpass bridge shown in Figure 1 is: (1) floor space is big, under land resources situation in short supply day by day, has strengthened construction cost, has also limited the employing at most of crossings in the city simultaneously; (2) turn left to detour 270 °, running distance is long, has increased energy consumption, has reduced efficient.The major defect of overpass bridge shown in Figure 2 is: the number of plies of intersecting is too much, and it is long to cause building height to increase with access bridge, and this has not only strengthened construction cost and operation maintenance cost, also makes structural performance, and especially anti-seismic performance descends greatly.

Summary of the invention

For solving the problems referred to above that prior art exists, the utility model will design a kind of complete interchange viaduct that floor space is little, building height is low, left turning vehicle no longer detours that possesses simultaneously.

To achieve these goals, the technical solution of the utility model is as follows: a kind of complete interchange viaduct comprises the overhead arterial highway in arterial highway, thing ground and north and south, have four crossings of East, West, South, North, there are five kinds of runways and a left and right sides lane change overpass bridge in each crossing; The runway of South Road mouth is by being followed successively by southwest from left to right towards the crossing to bend, the southeast is to bend, north south orientation straight way, north-south straight way and east southeast are to bend, described southwest is to bend, the southeast all is ground level roads to bend and east southeast to bend, described northern south orientation straight way links to each other with the east side runway of overhead arterial highway, north and south by access bridge, described north-south straight way links to each other with the west side runway of overhead arterial highway, north and south after crossing over northern south orientation straight way by left and right sides lane change overpass bridge, and link to each other North Road mouth runway and South Road mouth runway antisymmetry to bend with Nan Xi by overhead arterial highway, north and south; The runway of East Road mouth is by being followed successively by east southeast from left to right towards the crossing to bend, east northeast is to bend, west east orientation straight way, East and West direction straight way and North-East Bound bend, described east northeast links to each other with the east side runway of overhead arterial highway, north and south by access bridge to bend, described western east orientation straight way links to each other with the north side runway of arterial highway, thing ground by the ground bend, described East and West direction straight way is crossed over western east orientation straight way by left and right sides lane change overpass bridge and is linked to each other with the southern side runway of arterial highway, thing ground, and be connected West Road mouth runway and East Road mouth runway antisymmetry to bend with the southeast by arterial highway, thing ground.

Northern south orientation straight way described in the utility model links to each other with the east side runway of overhead arterial highway, north and south after crossing over the north-south straight way by left and right sides lane change overpass bridge; Described western east orientation straight way is crossed over the East and West direction straight way by left and right sides lane change overpass bridge and is linked to each other with the north side runway of arterial highway, thing ground.

The four corners of the world described in the utility model direction can be rotated arbitrarily under the certain intersecting angle situation in overhead arterial highway and arterial highway, ground guaranteeing.

Runway described in the utility model can be arranged to single road or arrange the road more according to the size of vehicle flowrate.

Compared with prior art, the utlity model has following beneficial effect:

1, because the utility model makes vehicle from either direction before entering the intersection, at first shunt the right-hand rotation vehicle to right-turn lane, then, craspedodrome and left lateral vehicle become by left and right sides lane change overpass bridge temporarily and keep left; After realization kept left, left turning vehicle can directly turn left to sail into left turn lane, and through vehicles recovers to keep to the right by the left and right sides lane change overpass bridge at crossing, opposite once more.Thereby realized " keep to the right during right-hand rotation, keep left during left-hand rotation ", made the vehicle of left-hand rotation under the rule of keeping to the right, realize the same natural, smooth and easy, quick with right-hand rotation.

2, because the utility model has realized that vehicle directly turns left, do not need the long radius bend that detours, reduced floor space greatly, be particularly suitable for narrow and small crossing, city.Compare with overpass bridge floor space shown in Figure 1, suppose that the left-hand rotation turning radius is 40m, so, total can reduce takes up an area of about 20,000 square metres.

3, because all fly-over junctions of the utility model all are the individual layer intersections, and building height is low, and access bridge is short, and cost is low, anti-seismic performance is good; Compare with the overall height of overpass bridge shown in Figure 2, building height can be reduced to 1/3rd.

4, because the utility model has realized that left turning vehicle need not cross over, no longer detour, shortened running distance, compare with the distance of overpass bridge shown in Figure 1, suppose left-hand rotation turning radius 40m, so, the left-hand rotation of four direction can reduce 1000m at least apart from amounting to, and each left turning vehicle lacks to walk the distance of 250m approximately.
