As shown in Figure 9, described stair step 26 1 sides are provided with bicycle ramp 27.
Described craspedodrome overpass bridge 2 is made up of no gap some bicycles road craspedodrome overpass bridge arranged side by side.
Described bridge floor supports driver's cabin, workplace and pedestrian's outlet is set in 11.
The course of work and principle:
When the present invention uses, assemble craspedodrome overpass bridge and left-hand rotation overpass bridge respectively;
The assembling of craspedodrome overpass bridge:
At first bridge floor is supported 11 drive units by himself and be driven to the predetermined area, and be parked on horizontal or vertical road craspedodrome road of intersection, symmetry is parked on two relative crossings, and telescopic prop 16 is put down it is landed, and rising bears a heavy burden does in order to reduce the supporting power of road wheel 15; In the process of driving this bridge floor support 11, upwards rotate in movable ramp 17, makes the driver can observe its place ahead; And then with garage's bridge floor 20 and bridge floor joint 29, transport to the predetermined area by special transport vehicle, and garage's bridge floor 20 is placed in two bridge floors supports on 11, the coniform boss 10 at bridge floor two ends is combined together with taper pit 19, square pit 18 on the bearing of square boss on the bridge floor joint 29 30 and bridge floor support is combined together, column 22 tops are inserted in the following column pit 9 in bridge floor middle part, some direct lanes are arranged on each direction, the craspedodrome overpass bridge of same quantity then is installed; People's Bank of China's ladder is installed on the sidewalk, ground, and People's Bank of China's attachment strap 24 two ends are connected with underpass mouth edge and attachment strap pillar 28 respectively; The elevator power supply is connected civil power, promptly finish the assembling of craspedodrome overpass bridge 2;
The assembling of left-hand rotation overpass bridge:
For the crossroad: at first bridge floor is supported on the 11 motor vehicle roadways that are positioned on the road at symmetrical crossing of crossroad; To stride road and bridge faces 7 again is positioned over two bridge floors and supports on 11, coniform pit 19 is combined together with coniform boss 10, on the ramp of bridge floor support 11, spacer assembly is set a side is isolated into pedestrian ramp, underpass attachment strap 23 is taken down, bridge floor supports 11 bottom surface so that the pedestrian can go directly, and exports the sidewalk, ground 5 that arrives the roadside thereby support interior pedestrian from this bridge floor;
For the T-shaped road junction: on two symmetrical crossing roads left-hand rotation overpass bridge 1 is installed respectively; The crossing is installed People's Bank of China and is crossed street overpass bridge 6 separately; Be installed between the People's Bank of China's ladder on the sidewalk, ground and cost People's Bank of China's attachment strap 24.
When this invention is used, when turning left for the vehicle on the either direction of crossroad such as needs, need to turn right through the People's Bank of China attachment strap below of craspedodrome overpass bridge, when reaching the left-hand rotation overpass bridge, turn left behind the up gradient by striding the road and bridge face, turn left again and sail down, proceed to craspedodrome overpass bridge garage's bridge floor or craspedodrome overpass bridge road under bridge section is passed through the crossroad along direct lane by the ramp; Pedestrian and bicycle can realize crossing road by the People's Bank of China's ladder on the craspedodrome overpass bridge and vertical lift ladder, pedestrian ramp that also can be by the left-hand rotation overpass bridge and stride passerby trade 8 and realize crossing road.
Unaffected for the vehicle of keeping straight in symmetry crossing, T-shaped road junction, the right side does not have the vehicle that needs to turn left in the symmetrical road at crossing and can realize by the left-hand rotation overpass bridge of the other end, the vehicle that needs to turn left in the crossing can be turned right earlier separately, and last left-hand rotation overpass bridge turns around to realize.Pedestrian and bicycle can be crossed the street overpass bridge by left-hand rotation overpass bridge, People's Bank of China and realize crossing road.
Police and staff can be in the workplaces in bridge floor supports, office or interim the rest.
