Enhancing inner support column 5 and outer support column 4 stability, the fixed connecting rod 11 between interior support column 5 and outer support column 4, will
Inner support column 5 and outer support column 4 connect integral, keep inner support column 5 and outer support column 4 more stable.
The weight of all steel lid beams 3 is undertaken since Cantilever Beams 8 are when being placed on sandbox 7 referring to Fig. 2, it is outstanding in order to increase
The load-bearing capacity of outrigger 8, welds ribs 84 between the top flange plate 81 and lower edge wing plate of Cantilever Beams 8, and ribs 84 is spaced
Arrange multiple tracks, ribs 84 is separately positioned on 82 two sides of web, and ribs 84 is installed in the portion that Cantilever Beams 8 stretch out steel bushing boots 32
Position.Since the position load-bearing capacity that the bottom wing listrium 83 of Cantilever Beams 8 is docked with steel bushing boots 32 is poor, in the upper table of steel bushing boots 32
Ribs 84 is welded and fixed between face and top flange plate 81, ribs 84 is close to the position of 8 bottom wing listrium 83 of Cantilever Beams, Ke Yizeng
The load-bearing capacity of strong Cantilever Beams 8 and 32 docking site of steel bushing boots, while keeping the connection between Cantilever Beams 8 and steel bushing boots 32 more steady
Gu.
Referring to Fig.1, since the present embodiment bridge construction is located at beside river, so the geology of construction area is relatively soft,
Depression is easy to produce under the action of pressure, so that the precision of the mounting height of steel lid beam 3 is influenced, in order to enhance the load-bearing energy on ground
Power prevents sinking of ground, is arranged with strip footing 12 in outer support column 4 and inner support column 5, strip footing 12 is poured for concrete
It builds to be formed, outer support column 4 and inner support column 5 are fixed by bolt and strip footing 12.
Work progress is as follows:
It is calculated first according to bridge coordinate before construction each for installing the position coordinates of 3 structure of steel lid beam, utilization
Pay-off equipment releases the position of Cantilever Beams 8 in 32 upper surface of steel bushing boots first.Cantilever Beams 8 are welded and fixed.According to calculating
Coordinate data out releases the position coordinates of outer support column 4 and inner support column 5 respectively, and outer support column 4 and inner support column 5 are consolidated
It is fixed to complete, spandrel girder 6 is set on outer support column 4, places sandbox 7 right above 4 center of outer support column on spandrel girder 6.Steel
3 integral hoisting of bent cap is supported steel lid beam 3 using the Cantilever Beams 8 on 7 supporting steel bent cap 3 of sandbox, while steel lid beam 3
Height is higher than setting height and the height of sandbox 7 is gradually decreased, until steel lid beam 3 reaches according to the height of measurement 32 top surface of steel bushing boots
To design height.When reaching the design height of steel lid beam 3, pads and pad at the gap that interior support column 5 and steel bushing boots 32 contact
Circle, makes inner support column 5 support steel lid beam 3；The height for continuing downward sandbox 7, separates sandbox 7 with Cantilever Beams 8.To steel lid beam
Casting concrete in 3 is removed outstanding on outer support column 4, inner support column 5 and steel bushing boots 32 after concrete reaches intensity requirement
Outrigger 8.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
