Compared with the prior art, the beneficial effects of the utility model are: delicate structure, floor space are little, reasonable in design, adopt radioactivity to extend project organization, do not influence vehicle ' on the main bridge during drainage, can effectively alleviate traffic jam issue.
Description of drawings Fig. 1 is the sketch of embodiment 1 of the present utility model.
Fig. 2 is the sketch of embodiment 2 of the present utility model.
Fig. 3 is the sketch of embodiment 3 of the present utility model.
Specific embodiment multiturn road junction double helix overpass bridge comprises that mainly many vertical support columns 1, high-altitudes are in the bridge floor 2 of level or class level, bridge floor is separated out two major trunk roads 3 in opposite directions at least, helicoidal structure is arranged in the highway section at bridge floor and major trunk roads corresponding ground crossing, and many extension roads 4 being set along the tangential direction in helical form highway section, each way of extension road and crossing is communicated with.But the bridge floor upper and lower settings becomes sandwich construction, and every layer of bridge floor all and between the ground is provided with helical form extension road, and can be interconnected by ring road between the adjacent extension road.Outwards expand bridge floor every one section bridge floor in the major trunk roads outermost, form abduction parking road surface 5.
Embodiment 1:
In the bridge floor on ground, helical form extension road can be set respectively for two independent support, and be communicated with to helical form extension road construction ring road, and ring road is on the tangent line of helical form extension road from major trunk roads separately.
As shown in Figure 1, two ring roads of design carry out the intersection misorientation of Different Plane in access bridge longitudinally, and the two-way access bridge of a broad is originally become two narrower two-way access bridges.Next, outside spiral section bridge floor of every access bridge design designs three bridge ring roads up and down respectively on these two spirals, two ring roads wherein lead to the cross traffic main line, another ring road inserts vertical main bridge, as the passage of the head end operation of longitudinal driving.The vehicle of desiring to turn right at the place, crossing only needs directly to turn on ground level road to get final product.Rightabout bridge construction design is identical.
The design feature of this overpass bridge is that it has overcome difficult problem that the crossroad extensively exists in the city nowadays " prohibit on a left side " rule and vehicle are reversed end for end in the other direction.
Example example 2:
In the bridge floor on ground, can between two bridge floors, set up helical form extension road for two independent support, and extend respectively towards two bridge floors along the tangential direction of extension road and to build ring road and be communicated with it.Up-run lane on the tangent line extension road of bridge floor spiral section or descending track quantity are identical with pairing crossing quantity on the ground.
As shown in Figure 2, A, B are vertical main bridge in this overpass bridge, and the A bridge vehicle can be selected after entering a spiral by the a1 ring road: turn left, reverse end for end through the a2 ring road through the a3 ring road.The a4 ring road can guide western vehicle to turn left to sail into main bridge through the a5 ring road.Each ring road running method of B bridge and A abutment are originally identical.This design also has two sped structures, and each helical structure has designed three ring roads too, and basic travel route does not have too big variation.Compare the scheme of embodiment one, the advantage of this scheme has been to add the structure of main bridge of vertical craspedodrome, allows the wagon flow of longitudinal driving directly pass through the crossing and is not subjected to the interference of other wagon flows.And the main bridge of this scheme all adopts one-way traffic, has avoided the danger of the vehicle head-on collision that two-way road may bring.
Embodiment 3:
As shown in Figure 3, four ring road double helix overpass bridges are the main bridge that has added horizontal craspedodrome on the basis of former three ring road double helix overpass bridges, i.e. C among the figure, D master's bridge.This scheme seems than three ring road overpass bridge complexity, but principle is basic identical in fact, increases a ring road mouth again at former three ring road spiral places exactly, and promptly the c1 among the figure, d1 ring road mouth connect laterally keep straight on main bridge C, D.This scheme only relates to two Different Plane, does not increase difficulty of construction.The traffic above-ground system that cooperates vehicle directly to turn right at the crossing ground level road can be dredged the problem of travelling of large-scale crossroad, city all directions of vehicle substantially smoothly.
During construction, can increase corresponding ring road quantity, make every road all communicate, and finally communicate, thereby effectively promote the convenience of traffic with main bridge with ring road accordingly according to overpass bridge present position and the road junction that relates to quantity.
In addition, the constructor can outwards expand bridge floor in the major trunk roads outermost every one section bridge floor, forms abduction parking road surface, when in main bridge generation traffic accident, for fear of causing traffic jam, can be used for temporary parking and use vehicle delivery to this road section surface.
