Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following specific embodiments are only
For illustrating the present invention rather than limiting the scope of the invention.It should be noted that word " preceding " used in the following description,
" rear ", "left", "right", "up" and "down" refer to that the direction in attached drawing, word "inner" and "outside" refer respectively to direction or remote
Direction from geometric center of specific component.
Suspension cable is force structure crucial in cable-stayed bridge, and cable saddle is the important embedded part for guaranteeing suspension cable force application location,
Therefore to ensure that Cable stress meets design requirement, the position of strict control cable saddle is needed in work progress；The position of cable saddle
Control includes needing to control the three-dimensional coordinate of cable saddle to, three directions of direction across bridge and elevation along bridge, and of the present invention one
The cable saddle positioning reinforcing device of kind of Cable-stayed Bridge Pylon by the shape of cable saddle, position, is highly fixed, is detected and surveyed with total station
Amount.
Work progress is:
1, it is saved under first sub-wire pipe and carries out vertical pre-buried four angle steel of setting-out, four angle steel before 9 coagulation of king-tower pours
What top connected is the positioning framework 2 of hollow out；
Etc. 2, after lower 9 concrete setting of section king-tower, the reinforcing of lateral bridging 6, the posting are carried out to positioning framework 2 with angle steel
Frame 2 is the square frame that angle steel is welded；
3, setting-out installs support platform 4, and the effect of support platform 4 is measurement elevation control, for controlling the absolute altitude of cable saddle；
4, jack chain block 3 is installed；
5, cable saddle 1 is hung tower top with tower crane, uses jack chain block 3 instead and slings 1 middle part of cable saddle, the backing plate at the cable saddle both ends
5 are placed in support platform 4, and hoisting point position rationally will guarantee cable saddle balance, prevent deflection, deformation；
6, with the center of total station method of polar coordinates control cord pannel plate mouth, cable saddle plan-position is adjusted with flower basket bolt, until two
Design position is all transferred at side backing plate center, and the center line of backing plate is overlapped with the position line；
7, backing plate 5 and support platform 4 carry out reinforcement of weld after being accurately positioned, it is ensured that its stability.
Supporting block 7 is equipped with below the support platform 4, the supporting block is welded as a whole with positioning framework 2, intensity
It is high, it is ensured that support platform 4 is indeformable.
