Embodiment 1
[0035] The maintenance method for joint reinforcement in this embodiment comprises the following steps:
[0036] Step 1, such as figure 2 As shown, a notch 6 is made at the position of the hinge joint 2; specifically, at the top of the hinge joint 2; when opening the notch 6, part of the structure of the bridge is chiseled at the position of the hinge joint 2 until the reinforcement structure is exposed. Specifically, in this embodiment, the asphalt pavement 3 and part of the concrete pavement 4 of the bridge are chiseled at the hinge joint 2 until the steel mesh 5 in the concrete pavement 4 is exposed, that is, the concrete pavement is chiseled out. Concrete above the reinforcement mesh sheet 5 in layer 4 until the reinforcement mesh sheet 5 is exposed.
[0037] Step 2, drilling a vertical through hole in the hinged joint 2; the vertical through hole is opened in the middle of the hinged joint 2. The diameter of the vertical through hole is usually smaller than the width o...
Embodiment 2
[0048] Such as Figure 4As shown, the reinforcement maintenance device of this embodiment includes: an upper anchoring plate 7; a lower anchoring plate 8, and the upper anchoring plate 7 and the lower anchoring plate 8 are arranged at intervals; A plurality of slurry outlet holes 11 are provided on the peripheral surface, and each slurry outlet hole 11 communicates with the hollow part inwardly; the upper anchor plate 7 and the lower anchor plate 8 can be arranged in cooperation with the tie rods 9 respectively.
[0049] One end of the tie rod 9 is provided with a fixed nut 12, and the fixed nut 12 can be buckled on the upper anchor plate 7 or the lower anchor plate 8; the other end of the tie rod 9 is provided with a screw thread 13 and a fastening nut 14; One end of the tie rod 9 has a communication port 10, which makes the hollow structure communicate with the outside; the slurry outlet holes 11 are located between the fixed nut 12 and the thread 13 of the tie rod 9.
