Moving device and gliding construction method.
Background technology
SPJ900/32 Bridge Erectors are designed to set up 900 tons of prestress box beams of high-speed railway, are supported using bilateral nose girder
On Ω type rear car door frames, box middle car crossbeam and front leg strut crossbeam, for adaptation to market variations and reduction cost, bilateral nose girder
Directly formed using eight or seven formula railway composed with emergency beams main truss component and fitting spelling groups, every 64 meters of nose girder length, weigh 110 tons.Build bridge
Machine needs to remove nose girder when crossing tunnel, and cross needs for nose girder to re-start assembly behind tunnel, crosses assembled on roadbed behind tunnel
During nose girder, need to set up bracing frame and lifted with two more than 200 tons cranes, when assembled on bridge floor, due to pier shaft height shadow
Ring, need crane tonnage very big when crane is stood under bridge(More than 400 tons);When crane stands on bridge floor, due to the sky of box beam
Box structure, crane stress point is only capable of propping up and is located at the web of beam body, causes crane leg to be unable to reach the state that stretch entirely, and then cuts down
The hoisting weight of crane, therefore nose girder must merogenesis built spelling.Above physical features and method, are required for large tonnage crane, run into
When mountain valley, river, support is not easy to set up, and causes construct consuming time length and construction cost height.
