When the pier 8 is square, the screw rod 12 is pushed to make the elastic clamping plate 14 fit the surface of the corner of the pier 8, and the second nut 13 is tightened to fix the screw rod 12. The steel sheet 15 is passed through the middle of the fixing block 16 at one end of the other elastic clamping plate 14, one end of the steel sheet 15 passes through the fixing groove 17 and is tightened, so that the steel sheet 15 holds the surface of the pier 8. At the same time, the elastic clamping plate 14 elastically bends after being pulled by the steel sheet 15, so that the steel sheet 15 fits the surface of the pier 8. Then the second bolt 18 is turned to fix the end of the second bolt 18 to the steel sheet 15. The piers 8 of different shapes are supported by the elastic clamping plate 14 and the steel sheet 15. By adding the steel sheet 15 at the ends of a plurality of elastic clamping plates 14 to tighten the pier 8, the contact area between the elastic clamping plate 14 and the pier 8 can be effectively increased, and various shapes of piers 8 can be effectively adapted, so that the hoop plate 1 and the pier 8 are closely fitted, reducing the replacement of the entire hoop plate 1 during construction. Only by tightening the steel sheet 15 can the piers 8 of different shapes be fixed and supported, which can effectively improve the flexibility and efficiency of construction, and effectively increase the friction between the elastic clamping plate 14 and the pier 8, which can effectively fix the hoop plate 1 on the pier 8, reduce the sliding or movement of the hoop plate 1 during construction, and effectively improve the stability of the entire bridge structure.

When the elastic splint 14 fails to fit with the pier 8, the pier 8 is supported by the support block 23. When the elastic splint 14 fits with the pier 8, the support block 23 enters the groove 2 by being squeezed. The support block 23 can provide an additional support point for the elastic splint 14, and can tightly connect the elastic splint 14 and the pier 8, effectively reducing the gap generated when the elastic splint 14 contacts the pier 8.

The paint spraying pipe 31 can enable the pier 8 to quickly connect the paint spraying equipment to the connecting pipe 32 when maintenance is required, thereby effectively reducing the time and operation of on-site installation and commissioning, and enabling the paint to be quickly and accurately positioned to the designated maintenance position, thereby effectively improving the overall efficiency of the maintenance work.

After the paint is discharged, it enters the inside of the collecting box 52, so that the paint is collected through the collecting box 52. Through the sealing plug 51, the inside of the paint spraying pipe 31 can be kept airtight during the paint spraying process, and the residual paint discharged from the inside of the paint spraying pipe 31 can be effectively collected through the collecting box 52, effectively reducing the waste caused by the paint residue, effectively improving the paint utilization rate and reducing the residue, and reducing the paint energy consumption and emissions.
[0029] As Figures 2 to 4 shown, a plurality of rubber blocks 6 are installed in the middle of the steel sheet 15; the plurality of rubber blocks 6 are slidably connected in the middle of the steel sheet 15; during operation, when the steel sheet 15 passes through the fixing groove 17 to tighten the pier 8, the plurality of rubber blocks 6 slide in the middle of the steel sheet 15. When the steel sheet 15 fits the surface of the pier 8, through the contact of the plurality of rubber blocks 6 with the surface of the pier 8, a buffer layer can be formed between the steel sheet 15 and the pier 8 due to the good elasticity of the rubber blocks 6, effectively increasing the frictional force between the steel sheet 15 and the pier 8 in contact, so that the steel sheet 15 can be stably attached to the pier 8.
[0030] During operation, place two hoop plates 1 on both sides of the pier column 8. The ends of the two hoop plates 1 are in contact.

When the pier column 8 is square, push the screw rod 12 to make the elastic splint 14 fit the surface of the corner of the pier column 8, and tighten the second nut 13 to fix the screw rod 12. Pass the steel sheet 15 through the middle of the fixing block 16 at one end of the other elastic splint 14. One end of the steel sheet 15 passes through the fixing groove 17 and is tightened, so that the steel sheet 15 holds the surface of the pier column 8. At the same time, after the elastic splint 14 is pulled by the steel sheet 15, it elastically bends, so that the steel sheet 15 fits the surface of the pier column 8. Then turn the second bolt 18 to fix the end of the second bolt 18 to the steel sheet 15. Support pier columns 8 of different shapes through the elastic splint 14 and the steel sheet 15. When the pier column 8 is square, during the process of pushing the screw rod 12 to make the elastic splint 14 fit the corner of the pier column 8, first make the support block 23 fit the surface of the pier column 8.

When the elastic splint 14 fails to fit the pier column 8, support the pier column 8 through the support block 23. When the elastic splint 14 fits the pier column 8, the support block 23 enters the groove 2 through extrusion. During the maintenance process of the pier column 8, connect one end of the connecting pipe 32 to the painting device, and apply a certain pressure to the middle of the connecting pipe 32 to make the paint enter the inside of the paint spraying pipe 31 and spray it onto the surface of the pier column 8 through multiple nozzles 33. After the painting is completed, push the push rod 4 to make the push plate 41 scrape the inner wall of the paint spraying pipe 31 to scrape off the paint adhering to the inner wall of the paint spraying pipe 31. When the push rod 4 pushes the push plate 41 to scrape from one end of the inner wall of the paint spraying pipe 31 to the other end, when one side of the push plate 41 contacts the end of the push block 5 and continues to push, when the sealing plug 51 is pushed away from the end of the paint spraying pipe 31, at the same time the collecting box 52 is pushed by the push plate 41 through the sealing plug 51 to slide at one end of the paint spraying pipe 31. The push plate 41 pushes the paint and discharges it from the end of the paint spraying pipe 31. After the paint is discharged, it enters the inside of the collecting box 52, so as to collect the paint through the collecting box 52. During the process of the steel sheet 15 passing through the fixing groove 17 to tighten the pier column 8, slide multiple rubber blocks 6 in the middle of the steel sheet 15. When the steel sheet 15 fits the surface of the pier column 8, contact the surface of the pier column 8 through multiple rubber blocks 6.
