Detailed description of the invention

By best embodiment, the present invention is described in detail below.

As shown in Figure 1-2, two-way six-lane crossing fast passing bridge, comprises the road 1 of right-angled intersection, and road 1 is two-way six-lane structure; The crossing of road 1 is provided with craspedodrome and is open to traffic bridge 3; The be open to traffic major function of bridge of keeping straight on makes the through vehicles of a direction by the effect rising height of bridge, the vehicle in other directions is allowed to pass through at the bottom of bridge, vehicle is changed in the position of solid space, thus avoids meeting, bumping against, ensure the faster traveling of vehicle.The craspedodrome bridge 3 that is open to traffic is arranged in left-right direction; Be provided with four left-hand rotations above road 1 to be open to traffic bridge 2; The bridge that turns left to be open to traffic is the deformation design of bridge of being open to traffic of keeping straight on, be two-way street is become one-way street, extend keep straight on be open to traffic bridge length, change the angle of bridge of being open to traffic of keeping straight on.The bridge 2 that turns left to be open to traffic is arranged at two roads 1 and intersects the rectangular area formed; The bridge 2 that turns left to be open to traffic is connected with the track, the leftmost side of the three lanes in the same way of road 1; Be open to traffic bridge 3 and the bridge 2 that turns left to be open to traffic of keeping straight on to be connected basic 4 with the plane of projection of bottom surface is provided with at the bottom of bridge; Connection basis at the bottom of bridge forms by being connected base unit at the bottom of multiple (depending on road and bridge basis surface width and crossing situation changeable) bridge, connecting base unit at the bottom of each bridge is exactly one piece of elongated steel sheet (being not limited only to steel plate) connected of can plugging into, the important component part ensureing that Bridge Foundation surface width is stable, be also support arcuate surface steady brace basis and prevent the excessive pedestal being absorbed in road surface of the stressed pressure of steady brace.The bridge that turns left to be open to traffic can also, according to different crossings situation and the different requirements that is open to traffic, be designed to multiple special shape, but general thought be identical with operating principle.Craspedodrome bridge 3 and the left-hand rotation bridge 2 that is open to traffic that is open to traffic is fixed with being connected at the bottom of bridge to be supported by steady brace 5 phase between basis 4.Steady brace is open to traffic to isolate the isolation pile in track below tread, is also the support column lifting the tread that is open to traffic, and is cone triangle body prefabricated component, and quantity is determined depending on be open to traffic tread width and load bearing requirements.Its Main Function is the effect by connecting upper and segmentation track, basis at the bottom of the weight transmitting of the tread that is open to traffic to bridge, key point be post bases in the vertical point being open to traffic tread and lane boundary, object is the traveling not affecting each track vehicle.
