Specific embodiment
Technical solution of the present invention is described in further detail with reference to the accompanying drawing.
It is shown in Figure 1, one kind for continuous T beam bridge without bracket maintenance and reinforcement operation platform and installation method, it is described to apply
Work stage+module method be included at the horseshoe inclined-plane of T web lower part be drilled with according to anchoring 11 force request of pedestal it is several identical straight
The hole of diameter and depth, punch position should avoid the reinforcing bar inside horseshoe；Surface dust in hole is cleaned up with hairbrush, then uses inflator
It blows off；Anchoring adhesive is injected since bottom hole with colloid-injecting gun, until glue is full of the 2/3 of hole inner volume；It is implanted into screw rod, and straight
To bottom hole, glue is just full of entire cavity at this time；Mustn't shake within 1 hour screw rod after the completion, and according to standard carry out scene with
