Abstract

A traffic by-pass bridge for crossing of roads in urban area is a multi level bridge structure and is composed of overhead level, ground level and underground level, cohich are linked by supporters to form a whole bridge. Each of level may be round about island, direct crossing, or their mixture.

Description

Traffic by-pass bridge for crossing of roads in urban area

The present invention relates to be applicable to a kind of traffic by-pass bridge for crossing of roads in urban area of city intersection pedestrian, bicycle and motor vehicle shunting.

Continuous development along with economic construction, the flow of urban population is increasing, various vehicles are more and more, and China belongs to developing country, this is just relatively backward for urban transportation facility, adds pedestrian, bicycle and motor vehicle and strives and travel that to cause traffic jam and traffic accident be customary in each city of China.Particularly even more serious at the parting of the ways, it has become the chronic disease that hinders urban economy development, and solution is preferably must one.

Crossroad in the city, generally be equipped with red, green light, allow the vehicle and the pedestrian of all directions pass through in an orderly manner, but the shortcoming of traffic lights is hemistich, half stops, and road utilization rate has only brought into play 50%, has caused the waste of resource, and, wait in line the current vehicle of green light and wait 1-20 minute sometimes at the bigger crossing of vehicle flowrate.Another kind of scheme is that rotary island shape (rotating disc type) is built up in the crossroad, and thin stream energy force rate is red, green light is strong slightly, but in the peak period, still has obstruction.Scheme is to build overpass bridge, viaduct etc. at the parting of the ways preferably, solved the problem of wagon flow at grade intersection preferably, but overpass bridge, viaduct all are to build on the ground, floor space is big, the bridge construction cycle is long, and is expensive big, general in, the small city is difficult to bear, the structure of bridge is more complicated also, and unfamiliar driver often has and to have gone up bridge and but be difficult to the phenomenon of bridge down.

It is little that purpose of the present invention designs a kind of floor space exactly, expensive little, the three-dimensional branching off bridge that shunting effect is good, its main feature is to have adopted underground, the face of land and sandwich construction on the ground, and be connected as a whole between the multilayer, each layer of multilayer can be a rotary island shape, also orthogonal type, also rotary island, orthogonal mixed type.

Traffic by-pass bridge for crossing of roads in urban area of the present invention, be the multilayer deck structure, it is characterized in that being provided with in the multilayer deck ground line with lower floor, it comprise ground plane layer, ground line with lower floor and ground line with the upper strata, connecting by supporting between each layer, is a general frame structure.A kind of scheme of multilayer deck is, ground flat bed, subterranean layer and aerial layer are rotary island disk shaped bridge floor, internal diameter and external diameter along rotary island, be respectively equipped with support column, ground, the face of land and underground rotary island are connected to integral body, each layer bridge floor is respectively motor vehicle bridge floor, bicycle bridge floor and pedestrian's bridge floor, and the four direction of each layer bridge floor is connected with in the street fast, slow lane and sidewalk by up gradient access bridge, plane access bridge, gug access bridge respectively.The upper strata is the fast traffic lane rotating disk, the ground flat bed is pedestrian's rotating disk, subterranean layer is the bicycle rotating disk, junction in rotating disk and street, fast traffic lane in the street is placed in the middle, and is connected with the upper strata rotary island by the upward slope access bridge, article two, nonmotorized vehicle lane is positioned at two sides of fast traffic lane, being connected with underground rotary island by the descending access bridge respectively, is two sidewalks in the outside of two nonmotorized vehicle lanes, and leading the way by the plane directly is connected with the Horizon rotary island.The another kind of scheme of multilayer deck is to be the craspedodrome bridge floor, but craspedodrome direction intersection, the fast traffic lane is placed in the middle on the craspedodrome bridge floor, and two outsides are nonmotorized vehicle lane, and outermost is the sidewalk, has People's Bank of China's ladder to communicate between each layer sidewalk.The third scheme of multilayer deck is keep straight on intersection bridge floor and one deck rotary island bridge floor mixed type, and rotary island is the turn inside diameter bridge floor.

Drawings and Examples:

Fig. 1 is the plan view (overlooking) of rotary island shape layer stereo bridge;

Fig. 2 is the hierarchical structure schematic diagram of rotary island shape layer stereo bridge;

Fig. 3 is the schematic perspective view of rotary island shape layer stereo bridge;

Fig. 4 is the structural representation (overlooking) of orthogonal shape layer stereo bridge;

Fig. 5 is a kind of turning mode of the three-dimensional bridge of orthogonal shape;

Fig. 6 is the structural representation of orthogonal and rotary island mixed type.

Referring to Fig. 1-3, A is the fast traffic lane, connects a layer express rotating disk by the ramp, and B is a nonmotorized vehicle lane, and by gug ground connection lower floor bicycle rotating disk, C is the sidewalk, and the ground plane rotating disk supports the load-bearing that combines as a whole with the bridge post respectively on the inside and outside footpath on shellring island.

The characteristics of shellring island formula grade separation are, with the existing plane rotary island joint in city, become three aspects in upper, middle and lower, enlarged three times through-current capability, and give express, slow train and pedestrian three aspects respectively, accomplished to take their own roads, do not disturbed mutually, and pedestrian's rotary island and ground line are flat, give conveniently, cost is lower, and floor space is little, and easy construction etc. are the characteristics of this bridge.People's Bank of China also can build the street crossing center garden in the rotary island center, and is attractive in appearance in order to the city.

Referring to Fig. 4, A ₁, B ₁, C ₁Be respectively fast traffic lane on the bridge, slow lane, sidewalk; A ₂, B ₂, C ₂Be respectively fast traffic lane under the bridge, slow lane, sidewalk.D, E, F, G are that bridge floor is pulled, and 1,2,3 is three bridge piers, and upper and lower bridge floor is combined as a whole.Sidewalk C under the bridge ₂Be located at outside 1, No. 3 bridge pier, and C ₂A is compared on the road surface ₂, B ₂Exceed 1M.At C ₁And C ₂Four joints, by People's Bank of China's ladder with C ₁And C ₂Link up.When this bridge was built, the thing road can be at the following 2M of Horizon, and the north and south road can link to each other with the Horizon street by the ramp access bridge separately at the above 2M of Horizon, and headroom is 4M between two layers, and actual upper strata is 2M only far from ground.Existing cross viaduct is the above two-layer intersection of the mutual disjunct ground line of face bridge in length and breadth, and the sense of huge monster is arranged.And that this bridge had both utilized was underground, utilized on the ground again, and was an integral body of interosculating, small and exquisite, was fit to the layout of little street corner, urban district.

Fig. 5 has set up four right-turning traffic road W between upper and lower layer on the basis of Fig. 4.For the left and right equal changed course of turning of the vehicle that solves the intersection bridge of keeping straight on is travelled, can take a kind of orthogonal and rotary island hybrid, article two, craspedodrome Xrds, article one, be built in subterranean layer, article one, be built in the ground flat bed, aerial layer is the rotary island rotating disk, specializes in turning vehicle and travels, and rotary island joins by the road surface of ramp access bridge and four direction.As shown in Figure 6.

After being built in the crossroad as the multilayer rotary island formula in the present patent application, orthogonal formula, orthogonal, the hybrid bridge of rotary island, be equipped with the pedestrian underpass more nearby in the street, traffic conditions will be greatly improved.
