Abstract
A 'pi' -shaped interchange overpass is characterized in that an elevated 'pi' -shaped overpass is arranged above a transverse H (longitudinal Z) road of an intersection and crosses the longitudinal Z (transverse H) road, a transverse part of the 'pi' -shaped overpass is a straight lane XX which is positioned above the transverse H (longitudinal Z) road and is parallel to the transverse H (longitudinal Z) road, a 'left-falling' DE and a 'vertical' BC of the overpass respectively represent left-turning ramps entering and exiting the straight main lane XX, and one ramp or an extension line DE thereof is intersected with the other ramp BC. The overpass has the advantages of small occupied area, low requirement on environment, large traffic capacity, less investment and wide application range, and can effectively solve the traffic jam at the intersection of the urban roads.
Description
The invention belongs to the design scheme of urban road intersection road, be specifically related to a kind of " π " shape interchange.
Urban traffic is the infrastructure in city, it is the important assurance that realizes city function, urban transport problems, particularly metropolitan traffic problems are ubiquitous " chronic diseases ", greatly restricting the development of urban economy, and at present, though the grade separation mode of urban road intersection is a lot of both at home and abroad, all exist to some extent some problems as:
1. simple grade separation: two road intersect, and are upper and lower straight-through and mistake does not have left lateral (or right lateral) route through overpass bridge respectively.This is more rare in the city, generally generally adopts on the speedway of countryside;
2. interchange:
Fig. 1-the 1st, the schematic diagram of incomplete cloverleaf interchange, it has reduced one or several left-hand rotation or right-hand rotation route, and the traffic capacity is than higher, but floor space is big, the construction cost height;
Fig. 1-2 is the schematic diagram of cloverleaf interchange completely, it has only a main-body structure thing, all left-hand bend traffic do not have any plane with all cross traffics and intersect, all right-hand bend traffic lines all use annular ramp to handle, thereby it is circuitous traffic to occur, influences the traffic ability in annular ramp, the also bad setting of the traffic sign of traffic method, and its floor space is too big, is difficult in the urban district implement;
Fig. 1-the 3rd, the schematic diagram of rhombus interchange, it takes up an area of few than clover leaf interchange, and right lateral is also more convenient, but left lateral has intersection, and local signal fluorescent tube reason need be set;
Fig. 1-the 4th, the schematic diagram of orthotype interchange, its left lateral vehicle does not need to detour, and can not interweave along direction running, and the occupation of land that has is less, but grade separation needs four-layer structure, and in all grade separations, bridge is a lot, generally needs the above bridge of all the people present;
Fig. 1-the 5th, the schematic diagram of ring-like interchange, enough big diameter is adopted on its circle island, takes up an area of about 4--5 hectare, and its conflict point is many, only adapts to the not too high intersection of design speed, is a kind of grade separation relatively more commonly used at present;
Fig. 1-the 6th, the schematic diagram of tubaeform interchange, it mainly adopts at T-shaped road junction place, this grade separation, the magnitude of traffic flow can not influence freely travels, but the road turning radius is restricted, and influences Vehicle Speed.
This shows, existing grade separation mode, or conflict point is many, need signalization fluorescent tube reason, or floor space is big, construction cost is big, is not suitable for adopting on the transport hub narrow in the urban road, that building is many, land used is difficult.
The present invention is directed to the deficiency that existing grade separation exists, a kind of city that is particularly suitable for is provided, can effectively solve urban road junction traffic jam, floor space " π " little, small investment shape interchange.
Of the present invention at " π " of intersection shape interchange, it is characterized in that crossing over vertical (laterally) road in horizontal (vertically) road top of intersection establishes one overhead " π " shape overpass bridge, one " horizontal stroke " that is somebody's turn to do " π " overpass bridge is to be positioned at horizontal (vertically) road top and to be parallel to the laterally direct lane of (vertically) road, one " cast aside ' and one " of this overpass bridge erected " represents the left rotaring ring road that enters and roll away from this craspedodrome A-road, wherein a ring road or its extended line and another ring road grade separation respectively.
For the decussation crossing, " π " of the present invention shape interchange, can crossing over vertically in the top of horizontal (vertically) road of intersection, (laterally) road be provided with two overhead " π " shape overpass bridges that direction is opposite, one " horizontal stroke " of two " π " overpass bridge is to be positioned at horizontal (vertically) road top and to be parallel to the laterally direct lane of (vertically) road, one " cast aside ' and one " of this overpass bridge erect " respectively representative enter and roll away from the left rotaring ring road of this craspedodrome A-road; wherein a ring road or its extended line and another ring road grade separation; two " π " shape overpass bridge is crossed over vertical (laterally) road and partly is in same plane and connects together the two abutting ends establishment body intersection of two overpass bridges; Also can be that two " π " shape overpass bridge is crossed over vertically (laterally) road and partly divided and be in different three layers of grade separations of plane formation.
Adopt " π " of the present invention shape interchange, enter the motor vehicles at each crossing of overpass bridge, all can directly travel to all directions on demand, not circuitous and loop line.All turn left and laterally no any plane intersects; All right-hand bends can turn at former ground surface, need not establish annular ramp; All elevated bridges are all directly built in Design Lane, generally do not need the expropriation of land enlarging.It is current in the simplest mode, and floor space is little, and is low to environmental requirement, and the traffic capacity is big, and expenditure of construction is low, and is applied widely; Also can solve the traffic problems of the intersection of travelling on the motor vehicle left side effectively; Can also be as required and ability, built by separate periods also comes into operation, for example, in main line and the crossing crossroad of branch line, shown in Fig. 6-3-1, can at first only build " π " shape grade separation pontic, can solve major part or main traffic direction problem so effectively, can reduce construction cost to greatest extent again, when pressing for, build " π " shape overpass bridge and previous combining again, finish the repertoire of crossroad.
" π " of the present invention shape interchange, can also realize three shuntings by building some accessory structures, building a circular passage under the former face of land travels for bicycle, between the former face of land and viaduct, build an overline bridge for people's walking, so just can be well with motor vehicle, bicycle and pedestrian's three shuntings, to guarantee quick and easy and safety.
