Description
Technical field
The present invention relates to bridge hauling construction system and bridge packaging technologies.
Background technique
Currently, with the rapid development of bridge technology, more and more long-span arch bridges are not due to can with other bridge types
The curve modeling and aesthetic feeling of analogy, and use is on water field of big area.But arch bridge main force structure -- arch rib is due to it
Weight is big, size is big, brings certain difficulty to construction, wherein it is that arch rib is applied that the arch rib of big segment, which is transported design position,
The key of work, specifically how by the entire arch rib being spliced on the bank or the arch rib fragmented transport being spliced into barge.
Currently, arch rib integral assembling is completed or, by after arch rib segmented assembly, using slide dilatory bracket delivery arch rib or
Arch rib segmentation, slippage bracket are set on slideway, are loaded with the slippage bracket of arch rib or arch rib segmentation by sliding on slideway, are moved
It moves on the barge equipped with slideway, then, barge drives to design together with the slippage bracket for being loaded with arch rib or arch rib segmentation
On navigation channel where position, achieve the purpose that transport arch rib.
Existing slippage bracket the problem is that, under walk leg bottom surface, ramp surface is plane, in slipping, sliding
Bracket easily slides out slideway, causes haulage time length, the low efficiency of arch rib, is unfavorable for the construction of arch rib.

Left end magnet base (39) and right end magnet base (40) are attracted.
2. bridge packaging technology according to claim 1, it is characterised in that: further include step A, finished in step 1
Afterwards, after handling door machine (4) hangs away equipped main body girder steel (6) from drawing vehicle (11), firstly, telescopic electric push rod (17)
The first workbench (16) is driven to retreat in rotating arm (14)；Then, rotary support (13) drives rotating arm (14) rotation one
180 degree；Secondly, drawing vehicle (11), which is affected from motor-car (12), returns to Liang Chang.
3. bridge packaging technology according to claim 2, it is characterised in that: repeat step 1 to step 4, simultaneously
Adjacent equipped main body girder steel (6) is connected by interim bar (9).
4. bridge packaging technology according to claim 3, it is characterised in that: step 5, in the middle part of bridge to be onstructed
It installs branch trestle (10)；When the nose girder (8) of the first starting segment unit (1) is docked with the nose girder (8) of the second starting segment unit (2)
Afterwards, nose girder (8) are removed, and the equipped main body girder steel (6) of the first starting segment unit (1) is originated into matching for segment unit (2) with second
Fill main body girder steel (6) docking.
5. bridge packaging technology according to claim 1, it is characterised in that: include following assembly before step 1
Supporting support (5) installation procedure；
Firstly, installing built-in fitting (51) on the ground；Then, bottom support bracket (52) is mounted on built-in fitting (51)；Secondly,
Assembled supporting support (5) is installed on shock absorption buffering mechanism (53)；Secondly, the two-way column plug cylinder of groups of assembly supporting support (5)
Intermediate cavity (55) is in parallel by hydraulic cylinder pipeline (60)；Again, hydraulic jack (62) or hydraulic pump and hydraulic cylinder pipeline (60)
Connection；And then, girder steel bracket (47) are installed in assembled supporting support (5) upper end；In next step, pacify between girder steel bracket (47)
Dress is for placing longitudinal driving device (27) and towed equipment girder steel pony sill (48).
