Abstract

The utility model discloses a novel urban overpass, belongs to the road bridges and aims to provide an urban overpass with small occupied area and simple structure. The novel urban overpass comprises a viaduct erected on the roadway; the viaduct (1) traverses a cross road; two ends of the viaduct are smoothly connected with the roadway through an approach bridge (2) respectively; U-shaped turning auxiliary bridges (3) are arranged on two sides of the viaduct (1) respectively; two ends of each turning auxiliary bridge (3) are smoothly connected with the roadway through the approach bridge (2) respectively; and branch bridges (4) smoothly connected with the turning auxiliary bridges (3) are arranged on two sides of the viaduct (1) in the right turning directions respectively. The utility model has the advantages of small occupied area, less construction investment, simple structure, small work amount, short construction period and the like, and relates to an ideal traffic facility which solves the problem of traffic jam at the prior urban intersection.

Description

The novel overpass bridge in city

Technical field: the utility model relates to a kind of road and bridge, relates in particular to a kind of urban interchange.

Background technology: along with the continuous increase of automobile pollution, the contradiction of traffic congestion becomes increasingly conspicuous; Particularly at the right-angled intersection of rush-hour, the traffic congestion phenomenon is of common occurrence especially in each metropolis; Various places government has built a large amount of mutilevel overpass for this reason, though the different overpass bridge of these forms has to a certain degree been alleviated traffic tension.Yet, because these overpass bridges mostly are three layers or sandwich construction greatly at present, many defectives such as ubiquity complex structure, floor space are big, long construction period, construction investment and engineering quantity are big, and the big many places, intersection of vehicle flowrate are in the bustling highway section of an inch of land is an inch of gold, and One's name is legion; Therefore these traditional mutilevel overpass can not adapt to the needs that urban traffic is built.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide the novel overpass bridge in a kind of floor space city little, simple in structure.

To achieve these goals, the utility model by the following technical solutions: it comprises the viaduct that is set up on the road surface; Viaduct is across right-angled intersection, and the two ends of this viaduct are respectively by access bridge and road surface smooth connection; Respectively be provided with a secondary bridge of turning that is the U font in the both sides of viaduct, the two ends of each secondary bridge of turning are respectively by access bridge and road surface smooth connection, are provided with and the bifurcated bridge of the secondary bridge smooth connection of turning along the right-hand bend direction respectively in the both sides of viaduct.

Compared with the prior art, the utility model is owing to respectively set up the secondary bridge of turning in the both sides of traditional viaduct, therefore solved effectively at right-angled intersection and waited for that because of vehicle all-clear causes the problem of blocking up easily, also can realize spot turn simultaneously and can not influence other vehicle pass-through; In addition, adopt technique scheme also three layers of traditional overpass bridge or sandwich construction can be reduced to double-layer structure, not only floor space is little, construction investment is few, but also has advantages such as engineering quantity is little, the duration is short.

Description of drawings:

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is a perspective view of the present utility model.

Among the figure: the secondary bridge 3 bifurcated bridges 4 of viaduct 1 access bridge, 2 turnings

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:

In Fig. 1～2, be set up in viaduct 1 on the road surface across right-angled intersection, the access bridge 2 and laterally road surface smooth connection of inclination is set respectively at the two ends of this viaduct bridge mouth place; Respectively be provided with one in the both sides of viaduct 1 and be U font or the secondary bridge 3 of horseshoe-shaped turning, the access bridge 2 and vertically road surface smooth connection of inclination are set respectively at the bridge mouth place, two ends of each secondary bridge 3 of turning, along the right-hand bend direction one section bifurcated bridge 4 and secondary bridge 3 smooth connections of corresponding turning are set respectively in the both sides of viaduct 1.

Being respectively example below to keep straight on, to turn left, to turn right, to turn around describes the function of this overpass bridge:

1) keeps straight on

Vertical through vehicles can pass right-angled intersection along original road surface of North and South direction and travel below viaduct 1 and two secondary bridges 3 of turning, horizontal through vehicles can stride across right-angled intersection along the viaduct 1 that east-west direction sets up and travel, thereby the vehicle that vehicle that the realization east-west direction is kept straight on and North and South direction are kept straight on is taken their own roads, and does not disturb mutually.

2) laterally turn left (is example to be turned left by east orientation south)

Vehicle reaches viaduct 1 from being positioned at viaduct 1 right-hand member, turn right then along bifurcated bridge 4, the secondary bridge 3 and sail down viaduct 1 of turning, below this viaduct, keep straight on again and pass right-angled intersection and can realize left-hand bend by north orientation south with the access bridge 2 that this secondary bridging of turning connects.

3) vertically turn left (by the south orientation west to serve as the example of turning left)

Vehicle is kept straight on below viaduct 1 from south to north and is passed right-angled intersection and reach the secondary bridge 3 of the turning that is positioned at viaduct 1 north side, sails down this secondary bridge of turning after the left-hand rotation and turns right and can realize left-hand bend.

4) spot turn (being example laterally to turn around)

Vehicle reaches viaduct 1 from the east orientation west, sail down viaduct 1 from the secondary bridge 3 of the turning that is positioned at viaduct 1 north side after turning right, below viaduct 1, keep straight on to pass by north orientation south then and reach the secondary bridge 3 of the turning that is positioned at viaduct 1 southern side behind the right-angled intersection again, sail down this secondary bridge of turning after the left-hand rotation and turn right again and can realize spot turn; Also can under the bridge floor of viaduct 1, directly turn around in the original place.

5) spot turn (being example vertically to turn around)

Vehicle is kept straight on below 1 from south orientation north from viaduct and is passed right-angled intersection and reach the secondary bridge 3 of the turning that is positioned at viaduct 1 north side, sail down after the left-hand rotation this turn secondary bridge by north orientation south once more below viaduct 1 craspedodrome pass right-angled intersection and can realize spot turn.

6) turn right

The vehicle of cross running and the vehicle of longitudinal driving all can be realized turning right according to original road, and mutual intersection can not take place, and this needn't give unnecessary details again.
