Abstract

The present invention is one fly-over for narrow city crossroads and aims at separating motor vehicles from non-motorized vehicles and making vehicles run without blocking in all directions. The present invention consists of one layer of overhead bridge connected to all roads at the crossroads, symmetrical back-bending bridges and straight bridges combined together. The present invention makes it possible to save land and money for city crossroads and raise the passage capacity of crossroads.

Description

Bi-directional symmetrical back-bending type vehicle classification is isolated the without hindrance capable overpass bridge of all directions

The present invention takes their own roads a kind of on narrow intersection, city motor vehicle and bicycle being separated, and no transverse barriers is isolated the without hindrance capable overpass bridge of all directions to a kind of intersection bi-directional symmetrical back-bending type vehicle classification that all directions are travelled simultaneously between each car.

In the present prior art, if make motor vehicle and bicycle interference-free mutually, and can be simultaneously between each similar car do not have the various overpass bridges that transverse barriers travels two big classes are arranged to all directions.The first kind is that the shared ground scope of bridge must exceed the shared ground scope of intersection.Therefore need to remove near the building in intersection.And have one will followingly earthward extend in the two road that intersect, and under ground line, intersect with another road, great in constructing amount like this, also easy and underground installation conflicts, and strengthens cost.Though the shared ground scope of another kind of bridge does not exceed the ground scope of road junction, but it is that " high-rise ratio " is bigger that the area of the top bridge floor of bridge accounts for the ratio of whole bridge floor areas, thereby cause the influence of sight aspect, city bigger, as 95114212.7 patent applications.

The present invention is the scope that will provide a kind of occupation of land not exceed intersection, and motor vehicle and bicycle are separated, and various vehicles all can not be subjected to simultaneously transverse barriers to travel and the city sight is influenced very little overpass bridge to all directions.It can save the soil around the city intersection, saves operating expenses and removal fund and can improve the bus capacity at crossing.

The object of the present invention is achieved like this, it is by four most of compositions, first is putting one on the shelf apart from only 4 meters of road surface height from intersection to the road surface that all directions road extends certain-length, be linked to be whole bridge, be called a bridge, this bridge floor simultaneously with between the road surface is connected with some support columns or bench-table towards ground, and bicycle and pedestrian can pass through in the space of non-support place.On rightabout two road, intersection, respectively build a back bending bridge across separated time top in the road, claim two bridges, these bridge floor two ends are connected by the dual-side of a bridge on slope access bridge and this road, make the left-hand bend motor vehicle by Chinese road travel rule, can travel along right edge from a bridge floor of intersection top, last back bending bridge access bridge is gone up 180 ° of back bending bridge revolutions bridge under the other end access bridge again, is back to right-hand rotation or craspedodrome again on one bridge floor of intersection along limit, bridge left side.This two back bending bridge is respectively second, third partly.The 4th partly is to build a straight-through bridge across intersection and its top one bridge floor, claims three bridges.The two ends of this bridge are connected to by the slope access bridge on the road surface in two road, and all straightgoing vehicles of crossing the crossing still normally travel on a bridge or three bridges.

Because the present invention is combined by four parts, therefore when first, second and third part or four parts make up, combination and other form overpass bridge of the prior art than other form have the complete and concentrated characteristics of advantage, " high-rise ratio " as it is little, take up an area of the road scope do not exceed the intersection, various types of vehicles can both the shunting shunting layering is unobstructed travels.

Specify below in conjunction with accompanying drawing:

Fig. 1 is a shape schematic diagram of the present invention.

Among Fig. 1,1 is a bridge floor, and it is to be linked to be the whole flat or bent plate of one deck above intersection and all directions road, and it and original path ground level are no more than 4 meters, with the support column or 2 connections of support bench-table of arbitrary shape.Bridge floor 1 promptly begins to connect to the road ground inclination after extending to certain-length above each road, forms access bridge 3.The width of the comparable bridge floor 1 of the width of access bridge 3 is narrow.This figure is example with the right-angled intersection, and each bar road is 4,5,6,7 by clockwise serial number, and corresponding bridge floor 1 above them is respectively 4-1,5-1,6-1,7-1.Middle separated time 7-5 across 5,7 liang of roads above 5,7 roads respectively has a back bending bridge 8 and 9, claims two bridge floors.8 with 9 middle separated time 8-9 each with after middle separated time on 5,7 roads becomes 90 ° to intersect, turn back to the road junction direction in two ends, 8,9 bridge floors are higher than bridge 1.8,9 liang of bridge floors are downward-sloping with middle separated time bending, are connected with 5-1,7-1 dual-side.Be connected by support column or bench-table 10 with the left and right sides and 5,7 pavement of road of 5-1,7-1 respectively below the bridge plate.The access bridge 3 of 5-1,7-1 also can be divided into two partly, tilts to connection to 5,6 pavement of road gradually respectively again after the part of middle separated time both sides also can be inclined upwardly certain altitude earlier.5-1, limit, the 7-1 left and right sides partly are not inclined upwardly, and directly connect to the road ground inclination, and (seeing that dotted line partly among the figure) can save back bending bridge 8,9 like this, makes back bending on 5 or 7 roads of vehicle below acclivitous access bridge 3.Three bridge floors be one from last across separated time 7-5 the 5-1 on the intersection, the 7-1, the downward-sloping straight-through bridge 11 that tilts to be connected with 4,6 pavement of road and 4-1,6-1 bridge floor in two ends, its bridge floor is higher than one, two bridge floors, bridge 11 towards between following and bridge floor 1 and 4,6 pavement of road with the support column of arbitrary shape or support bench-table 12 and be connected.But supporting and space traffick not.The middle separated time of bridge 11 intersects with the middle separated time of 5-1 and 7-1.

Motor-driven vehicle going route explanation of the present invention is an example with 6,7 liang of road drivings only, 4,5 and 6,7 symmetries.6, the straightgoing vehicle of 7 roads is all kept straight on by the cruising route.Pass through from straight-through bridge 11 and bridge 1, see 6H, 7H.The left turning vehicle of 6 roads is gone up access bridge 3 earlier and is gone up bridge floor 1 to crossroad mouth again and turn right into the 5-1 right side, moves ahead and goes up back bending bridge 8, turns to 180 ° of opposite side to crossroad mouths from the suitable access bridge of bridge 8 other ends down to 5-1 crossing that moved ahead to enter 7-1 along bridge, sees 6z.The right-hand bend car of 6 roads is gone up access bridge 3 earlier and is gone up bridge 1 again to the right-hand rotation of crossroad mouth, sees 6y.The left turning vehicle of 7 roads is gone up access bridge 3 earlier and is gone up bridge floor 1 to the crossroad mouthful laggard 5-1 that makes a slip of the tongue again and lean on to the right, moves ahead and goes up back bending bridge 8, and suitable bridge turns to 180 °, turns right down to 5-1 opposite side to crossroad mouth from bridge 8 other end access bridges, advances 4-1, sees 7z.7 road right-hand bend cars are gone up earlier access bridge 3 and are gone up bridge floor 1 to the crossroad mouth into 6-1 that turns right again, see 7y.

The direction of straight-through bridge 11 also can horizontally rotate 90 °, and separated time intersects with the middle separated time 6-4 of 4-1,6-1 in becoming, and two ends are connected with 5-1,7-1.See that dotted line partly among the figure.
