[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figures 1-5 The diagram shows a basalt fiber corrugated plate adaptive lining device for tunnels, including an inner lining plate 1. The inner lining plate 1 is made of basalt fiber as a reinforcing material and is composited with a matrix such as resin. The inner lining plate 1 is generally arranged in an arc-shaped corrugated shape. It also includes a clamping component disposed on the inner lining plate 1 for adaptive support and clamping with the tunnel.

[0023] The clamping assembly includes multiple fixed tubes 201 that are fixedly connected to the trough of the inner liner plate 1 and are arranged at equal intervals. Each fixed tube 201 has a sliding rod 202 slidably connected to one end away from the inner liner plate 1. Each fixed tube 201 is provided with a telescopic assembly for telescopically extending and retracting the sliding rod 202. One end of each sliding rod 202 is fixedly connected with a semi-circular sleeve 203. Each semi-circular sleeve 203 is rotatably connected with a clamping ball 204. The inner liner plate 1 is provided with a locking assembly for locking each sliding rod 202 after telescopic extension and retraction.

[0024] It should be noted that by setting up the clamping component, the inner lining plate 1, in conjunction with the telescopic component and the locking component, not only achieves the support and reinforcement of the tunnel, but also adapts to the dimensional errors of the tunnel inner wall, thereby improving the sufficiency of the contact between the inner lining plate 1 and the tunnel inner wall, and thus improving the effectiveness of the tunnel reinforcement.

[0025] Please see Figure 5 The telescopic assembly shown in the figure includes a telescopic plate 301 that is slidably connected inside the fixed tube 201. The end of the sliding rod 202 away from the semi-circular sleeve 203 is connected to the telescopic plate 301. A spring 302 is fixedly connected to the side of the telescopic plate 301 away from the sliding rod 202. The end of the spring 302 away from the telescopic plate 301 is connected to the bottom wall of the fixed tube 201.

[0026] It should be noted here that the telescopic component is used to push the clamping ball 204 to fit tightly against the inner wall of the tunnel.

[0027] Please see Figure 5The locking assembly shown in the figure includes a locking rod 401 slidably connected to the trough of the inner liner plate 1. The locking rod 401 is slidably connected to each fixed tube 201 and is located between the side of the telescopic plate 301 away from the spring 302 and the top of the fixed tube 201. The locking rod 401 has multiple wedge-shaped grooves 402, and each wedge-shaped groove 402 is arranged opposite to the sliding rod 202. The inner liner plate 1 is provided with a driving assembly for driving the locking rod 401 and a guiding assembly for guiding the locking rod 401 during the driving process.

[0028] It should be noted here that: by setting up the locking assembly, the sliding rod 202 is locked and fixed by the wedge groove 402 on the side wall of the locking rod 401 and the wedge action of the sliding rod 202, thereby making each abutting ball 204 firmly abut against the inner wall of the tunnel.

[0029] Working principle: When reinforcing a tunnel, the inner lining plate 1 with an arc-shaped corrugated design is placed against the inner wall of the tunnel. Then, the inner lining plate 1 is fixed to the tunnel. By splicing the inner lining plates 1 together, the inner lining plate 1 is laid on the inner wall of the tunnel. Since the inner lining plate 1 is a corrugated plate made of basalt fiber as the reinforcing material and composite with resin and other matrices, the good impact resistance, corrosion resistance and lightweight characteristics of the inner lining plate 1 can be utilized to improve construction efficiency and shorten the construction period while reinforcing the tunnel.

[0030] Furthermore, during the laying of the inner lining plate 1, when the inner lining plate 1 abuts against the inner wall of the tunnel, the multiple abutting balls 204 on the inner lining plate 1 will abut against the inner wall of the tunnel under the elastic action of the telescopic component. After the inner lining plate 1 is fixed in the tunnel, the locking rod 401 can be moved by the cooperation of the drive component and the guide component. Then, the sliding rod 202 is locked and fixed by the wedge groove 402 on the side wall of the locking rod 401 and the wedging action of the sliding rod 202. This makes each abutting ball 204 firmly abut against the inner wall of the tunnel. By using the abutting action of each abutting ball 204, the tunnel is supported and reinforced at the same time, and the dimensional error of the inner wall of the tunnel is accommodated. This improves the sufficiency of the contact between the inner lining plate 1 and the inner wall of the tunnel, thereby improving the effectiveness of the tunnel reinforcement.

[0031] Example 2

[0032] Please see Figure 4 This embodiment further illustrates Example 1. The guide assembly shown in the figure includes a first fixing plate 501 fixedly connected to the trough of the inner lining plate 1. A guide frame 502 is fixedly connected to the side of the first fixing plate 501 near the locking rod 401. A guide plate 503 is slidably connected to the guide frame 502. The side of the guide plate 503 away from the first fixing plate 501 is connected to the locking rod 401.

[0033] It should be noted that by setting up the guide component, the guide frame 502 and the guide plate 503 work together to guide and limit the movement of the locking rod 401, thereby ensuring the stability of the movement of the locking rod 401.

[0034] Example 3

[0035] Please see Figure 3 This embodiment further illustrates other embodiments. The driving assembly shown in the figure includes a second fixing plate 601 fixedly connected to the trough of the inner lining plate 1. The second fixing plate 601 and the first fixing plate 501 are symmetrically arranged about the locking rod 401. The second fixing plate 601 is slidably connected to two T-shaped rods 602. One end of the two T-shaped rods 602 is fixedly connected to a connecting plate 603. The end of the locking rod 401 away from the first fixing plate 501 is connected to the connecting plate 603. The second fixing plate 601 is threadedly connected to a T-shaped threaded rod 604. The T-shaped threaded rod 604 is located between the two T-shaped rods 602, and one end is connected to the connecting plate 603.

[0036] It should be noted that when the locking rod 401 needs to be moved, the T-shaped threaded rod 604 can be rotated. The threaded engagement between the T-shaped threaded rod 604 and the second fixed plate 601, as well as the guiding action of the two T-shaped rods 602, will drive the connecting plate 603 to move, thereby realizing the movement of the locking rod 401.

[0037] What's even better is that, in the existing publicly available technology, there are multiple ways to prevent loosening of the T-type threaded rod 604, which can be used selectively.

[0038] Please see Figure 3 The T-shaped threaded rod 604 in the figure has a drive hole (not shown here) at the end away from the connecting plate 603. The drive hole is set in a regular hexagon.

[0039] It should be noted that by setting a regular hexagonal drive hole at one end of the T-shaped threaded rod 604, it is convenient to rotate the T-shaped threaded rod 604.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
