The system comprises a floating transportation device, a floating dragging system and an anchoring positioning system, wherein the floating transportation device consists of at least two floating ships; the floating transportation system is formed into a two-point simple support floating dragging system through a floating pier support point upper slideway and a steel girder tail part joint slideway at the top end of a floating pier bracket. The anchoring positioning system consists of shoreside anchoring devices, conventional pier anchoring and anchoring ships which are connected with positioned through steel wire ropes and floating transportation devices.
Description
Technical field
The utility model relates to the construction installation of steel truss girder bridge, particularly the floating drag anchor fixed bit system of a kind of floating high Dun great Kua Duganghengliangqiao that drags method construction for steel purlin bridge.
Background technology
In recent years, along with the development that Bridges in Our Country is built, steel truss girder is lightweight with it, integral rigidity is large, span ability is strong, on bridge construction, is widely used.The construction method of steel truss girder has full framing, free cantilever erection, nose girder is dilatory, transportation by driving is dilatory.The obvious advantage such as transportation by driving is dilatory has short construction period, good economy performance, the time of stopping navigation is short, is used on the river that the navigation of being everlasting requires.The dilatory method of steel truss girder transportation by driving in the past is mainly applicable on squat pier, the bridge that lightweight, span is little, floating drag way in the unsafe factor such as the floating pier inclination that causes of water-pumping/draining comparatively outstanding, floatingly drag computational process also more complicated.
Utility model content
Technical problem to be solved in the utility model is to provide the floating drag anchor fixed bit system of a kind of high Dun great Kua Duganghengliangqiao, to increase floating stability, the saving duration of dragging in process of steel truss girder, simplify the floating computational methods of dragging, significantly promote floating drag safety and reliability in process.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
The floating drag anchor fixed bit system of a kind of high Dun great Kua Duganghengliangqiao of the present utility model, comprises transportation by driving device, floating towed body system and anchor and position system, it is characterized in that: described transportation by driving device is made up of at least two pontoons; Described transportation by driving system comprises that longitudinal separation is arranged on two floating pier supports of transportation by driving device, and the floating pier fulcrum sliding way girder steel afterbody node sliding way that is arranged at floating pier cantilever tip forms the floating system of dragging of 2 freely-supporteds; Described anchor and position system is by the bank anchor device, existing bridge pier grappling and the anchoring ships that are respectively connected location by wire rope with transportation by driving device.
The beneficial effects of the utility model are that pontoon parallel connection forms transportation by driving device, flexible to tonnage of ship demand; Adopt 2 the floating towed body of support systems, whole floating dragging in process, the jacking force of floating pier is constant, the floating unsafe factors such as floating pier inclination that in way, water-pumping/draining causes that drag are got rid of, effectively overcome current in pushing tow process, wind-force, water level and the adverse effect of navigation to pontoon stability, ensured steady, safety, reliable when girder steel moves.
