[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-4 As shown in the figure, the present invention provides an anchor for bridge and tunnel reinforcement, including a fixing ring 1, a connecting pipe 2 fixedly connected to the bottom surface of the fixing ring 1, a bolt 3 provided inside the connecting pipe 2, a fixing pipe 4 provided at the bottom end of the connecting pipe 2, and a plurality of adjusting holes 5 opened at equal angles on the outer wall surface of the fixing pipe 4. A pressing plate 6 is fixedly connected to the top surface inside the adjusting hole 5, and an adjusting component is provided inside the adjusting hole 5 for adjusting the position of the pressing plate 6.

[0027] In this embodiment, by setting a fixing pipe 4, the worker first fixes the fixing pipe 4 to the bottom end of the connecting pipe 2, drills two holes of different sizes in the concrete substrate, blows away the floating dust and residue in the holes, and then places the bolt 3 and the fixing pipe 4 into the drilled hole. Using a wrench, the bolt 3 is turned so that it can be threaded into the drilled hole under the action of the thread. Then, the steel mesh and the anchor are tied with thin iron wire to reinforce the bridge and tunnel. When the bolt 3 is rotating, the adjusting component can squeeze the extrusion plate 6, so that the extrusion plate 6 can move inside the adjusting hole 5, and one side of the extrusion plate 6 can be tightly attached to the inner wall of the drilled hole, thereby increasing the stability of the bolt 3. Even without pouring adhesive into the inner wall of the drilled hole, the fixing ring 1 can still be fixed to the wall, which facilitates the later reinforcement of the bridge and tunnel. At this time, the worker adds adhesive into the drilled hole to further improve the stability of the bolt 3 after fixing. At the same time, it can prevent the bolt 3 from falling out of the drilled hole when the adhesive becomes less sticky after a certain period of use, thereby improving the service life of the reinforced bridge and tunnel.

[0028] Specifically, the adjusting component includes an adjusting block 7, which is movably fitted inside the adjusting hole 5. A threaded groove is provided on one side of the adjusting block 7, and the adjusting block 7 is threadedly connected to the bolt 3. Limiting grooves 8 are provided on both the left and right sides inside the adjusting hole 5, and one side of the adjusting block 7 is attached to one side of the extrusion plate 6.

[0029] In this embodiment, by setting the adjusting block 7, since the adjusting block 7 is threadedly connected to the bolt 3, when the bolt 3 rotates, the adjusting block 7 can move up and down inside the adjusting hole 5 to press the extrusion plate 6, so that one side of the extrusion plate 6 can fit together with the inner wall of the drill hole.

[0030] Specifically, limit blocks 9 are fixedly connected to both the left and right sides of the adjusting block 7, and the limit blocks 9 are movably fitted together with the limit groove 8;

[0031] In this embodiment, by setting a limiting block 9, and by movably fitting the limiting block 9 and the limiting groove 8 together, the limiting block 9 can limit the adjustment block 7.

[0032] Specifically, a connecting ring 10 is movably sleeved on the outside of the connecting pipe 2, and several fixing pieces 11 are fixedly connected to the outer wall surface of the connecting ring 10;

[0033] In this embodiment, by setting fixing pieces 11, several fixing pieces 11 can fasten the newly added steel mesh and further enhance the bonding force between the new and old materials.

[0034] Specifically, a number of extrusion blocks 12 are fixedly connected to one side of the extrusion plate 6, and a gasket 13 is movably sleeved on the outside of the connecting pipe 2.

[0035] In this embodiment, by setting extrusion blocks 12, a number of extrusion blocks 12 can increase the friction between the extrusion plate 6 and the inner wall of the drill hole, thereby improving the fixing effect of the fixing tube 4.

[0036] Specifically, the bottom surface of the connecting pipe 2 is provided with an installation groove 14, and the top end of the fixing pipe 4 is fixedly connected with an installation frame 15, which is movably installed together with the installation groove 14.

[0037] In this embodiment, by setting the mounting frame 15, the mounting frame 15 and the mounting groove 14 are movably installed, so that the fixing pipe 4 can be fixed at the bottom end of the connecting pipe 2.

[0038] Work steps: 1. By setting up the fixing pipe 4, the worker first fixes the fixing pipe 4 to the bottom end of the connecting pipe 2. After drilling two holes of different sizes in the concrete substrate and blowing away the loose dust and residue in the holes, the bolt 3 and fixing pipe 4 can be placed in the drilled holes. The bolt 3 is then tightened with a wrench so that it can be threaded into the drilled hole. Then, the steel mesh and the anchor are tied with thin iron wire to reinforce the bridge and tunnel. When the bolt 3 is rotating, the adjusting component can squeeze the squeezing plate 6, so that the squeezing... The pressure plate 6 can move inside the adjustment hole 5, so that one side of the pressure plate 6 can be tightly fitted to the inner wall of the borehole, thereby increasing the stability of the bolt 3. Even without pouring adhesive into the inner wall of the borehole, the fixing ring 1 can still be fixed to the wall, which facilitates the later reinforcement of the bridge and tunnel. At this time, the workers add adhesive into the borehole to further improve the stability of the bolt 3 after it is fixed. At the same time, it can prevent the bolt 3 from falling out of the borehole when the adhesive becomes less sticky after a certain period of use, thereby improving the service life of the bridge and tunnel reinforcement.

[0039] Second, by setting the adjusting block 7, since the adjusting block 7 is threadedly connected to the bolt 3, when the bolt 3 rotates, the adjusting block 7 can move up and down inside the adjusting hole 5 to press the extrusion plate 6, so that one side of the extrusion plate 6 can fit together with the inner wall of the drill hole. By setting the mounting frame 15, since the mounting frame 15 is movably installed with the mounting groove 14, the fixing pipe 4 can be fixed at the bottom end of the connecting pipe 2.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
