The course of work and principle:
When the present invention uses, assembling craspedodrome viaduct and left-turn flyover respectively;
The assembling of craspedodrome viaduct:
First bridge floor is supported 11 and be driven to the predetermined area by the drive unit of himself, and on the transverse direction being parked in intersection or longitudinal road craspedodrome road, symmetry is parked on two relative crossings, and is put down by telescopic prop 16 and make it land, the supporting power that rising bears a heavy burden does in order to reduce road wheel 15; In the process of driving this bridge floor support 11, mov-ing ramp 17 upwards rotates, and makes driver can observe its front; And then by garage's bridge floor 20 and bridge floor joint 29, the predetermined area is transported to by special transport vehicle, and garage's bridge floor 20 is placed in two bridge floors supports 11, the coniform boss 10 at bridge floor two ends is combined together with taper pit 19, square pit 18 on the bearing support the square boss 30 on bridge floor joint 29 and bridge floor is combined together, first column 22 top is inserted in the column pit 9 below in the middle part of bridge floor, each direction there are some Through Lanes, then the craspedodrome viaduct of same quantity is installed; Be arranged on by People's Bank of China's ladder on pavement, ground, People's Bank of China's attachment strap 24 two ends are connected with underpass mouth edge and attachment strap pillar 28 respectively; Elevator power supply is connected civil power, namely completes the assembling of craspedodrome viaduct 2;
The assembling of left-turn flyover:
For crossroad: first bridge floor is supported 11 and be positioned on the motor vehicle driveway on the road at the symmetrical crossing of crossroad; To be positioned over two bridge floors across road and bridge face 7 again supports on 11, coniform pit 19 is combined together with coniform boss 10, the ramp of bridge floor support 11 arranges spacer assembly side is isolated into pedestrian ramp, underpass attachment strap 23 is taken down, with make pedestrian can go directly bridge floor support 11 bottom surface, thus the pedestrian in supporting from this bridge floor exports and arrives the pavement, ground 5 in roadside;
For T-shaped road junction: two symmetrical crossing roads install left-turn flyover 1 respectively; Pedestrian crossing viaduct 6 is installed at independent crossing; Be arranged between the People's Bank of China's ladder on pavement, ground and cost People's Bank of China's attachment strap 24.
When this invention uses, for the vehicle in the either direction of crossroad as needs turn left time, need to turn right below People's Bank of China's attachment strap of craspedodrome viaduct, when reaching left-turn flyover, turn left by across road and bridge face after up gradient, turn left again and to be driven off by ramp, proceed to craspedodrome viaduct garage's bridge floor along Through Lane or craspedodrome viaduct road under bridge section passes through crossroad; Pedestrian and bicycle can cross road by the People's Bank of China's ladder on craspedodrome viaduct and the terraced realization of vertical lift, also by the pedestrian ramp of left-turn flyover and realize crossing road across passerby trade 8.
The vehicle of keeping straight on for symmetrical crossing, T-shaped road junction is unaffected, right side realizes without the left-turn flyover of the vehicle needing in the symmetrical road at crossing to turn left by the other end, need the vehicle turned left first to turn right in independent crossing, upper left-turn flyover turns around to realize.Pedestrian and bicycle can realize crossing road by left-turn flyover, pedestrian crossing viaduct.
Police and staff can workplaces in bridge floor supports, office or temporarily have a rest.
