[0017] 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 based on this application are within the protection scope of the present utility model.

[0018] This utility model relates to a tunnel lining crack repair device, which is mainly designed for lining cracks in tunnel engineering. With economic development, a large number of tunnels have been built. However, tunnel linings are affected by multiple factors such as construction technology, geological conditions, and environmental erosion, and the linings are prone to cracks of varying degrees. The broken linings are also very easy to fall off, causing safety hazards.

[0019] To address the aforementioned technical problems, this application provides a tunnel lining crack repair device. The basic concept is as follows: anchor rods are driven into the intact lining from both sides of the crack, and one end of the anchor rod extending outside the lining is fixedly connected by a connecting rod to prevent further expansion of the crack. Simultaneously, a support rod is installed at the bottom of the crack, with one end fixedly installed to the connecting rod, and the other end supported by a support block against the bottom of the crack. This facilitates the bonding of the repaired crack with adhesive, ensuring effective repair and providing support for the broken lining, thus preventing lining collapse and potential safety hazards.

[0020] Based on the above basic concept, the following are different embodiments for illustration: A tunnel lining crack repair device, such as Figure 1As shown, the system includes two anchor rods 1, which are respectively arranged on both sides of the lining crack 2. One end of each anchor rod 1 passes through the lining 3 and extends into the tunnel soil for fixation. The other ends of each anchor rod 1 are fixedly connected by a connecting rod 4. A support rod 5 is provided directly below the connecting rod 4 and a support block 6 is provided at one end of the support rod 5. The other end of the support rod 5 is fixedly installed to the connecting rod 4. In this embodiment, the two anchor rods 1 are driven into the intact lining 3 on both sides of the lining crack 2. Specifically, holes are drilled into the intact lining 3 on both sides of the lining crack 2, with the depth of the holes extending into the tunnel soil. Then, the two anchor rods 1 are inserted into the drilled holes so that one end of the anchor rod 1 passes through the lining 3 and extends into the tunnel soil. Glue is injected into the drilled holes to firmly fix the driven ends of the anchor rods 1 on both sides of the lining crack 2. The ends of the anchor rods 1 that extend outside the lining 3 are fixedly installed by the connecting rod 4, so that the two anchor rods... 1. A U-shaped structure is formed with the connecting rod 4, which connects the two sides of the lining crack 2 to prevent the lining crack from expanding further. Secondly, a support rod 5 is designed directly below the lining crack 2. One end of the support rod 5 is equipped with a support block 6, which is used to support the lining crack 2 from the bottom up. The support block 6 has two functions in supporting the lining crack 2: on the one hand, it is convenient to fix the adhesive after the crack is repaired with glue, thereby improving the repair efficiency and quality of the lining crack; on the other hand, it prevents the broken lining from falling and causing safety hazards.

[0021] This application provides a preferred embodiment in which the support rod 5 comprises a plurality of rods, each of which is integrally formed with the support block 6. In this embodiment, the number of support rods 5 is further limited to a plurality, and the support rods 5 and the support block 6 are integrally formed by stamping, which improves the structural strength of the device and makes it less prone to deformation during the support of the lining crack 2.

[0022] This application provides a preferred embodiment, such as... Figure 1 As shown, the support block 6 has an arc-shaped curved surface structure, and the radius of curvature of the arc-shaped curved surface structure is the same as the radius of curvature of the lining 3. In this embodiment, the shape of the support block 6 is further defined. By designing the support block 6 as an arc-shaped curved surface structure that matches the lining 3, that is, the radius of curvature of the support block 6 is the same as the radius of curvature of the lining 3, the support block 6 can better fit on the lining 3 when supporting the lining crack 2. This is beneficial to improve the ability of the adhesive injected into the lining crack to quickly and stably solidify and form during the repair of the lining crack by the device of this application, preventing the adhesive from bulging downward under the action of gravity, and preventing gaps from appearing in the repair inside the lining crack.

[0023] This application provides a preferred embodiment, such as... Figure 1 As shown, the other ends of the two anchor rods 1 are fixedly connected to the connecting rod 4, and the other end of the support rod 5 is fixedly connected to the connecting rod 4 via cross-shaped clips 7. In this embodiment, the anchor rod 1 and the connecting rod 4 are further defined as being fixedly connected via cross-shaped clips 7, and the support rod 5 and the connecting rod 4 are also fixedly connected via cross-shaped clips 7. By fixing the anchor rods and connecting rods, and the support rods and connecting rods with cross-shaped clips, the device of this application has the structural characteristics of convenient assembly and disassembly, firm connection, and strong versatility during use.

[0024] This application provides a preferred embodiment, such as... Figure 1 As shown, the two anchor rods 1, the connecting rod 4, and the support rod 5 are all threaded rods. Each of the two anchor rods 1, the connecting rod 4, and the support rod 5 has a first nut at both ends of the cross-shaped latch 7 to lock the cross-shaped latch 7 axially. In this embodiment, the anchor rods 1, the connecting rod 4, and the support rod 5 are further specified to be threaded rods. Simultaneously, the first nut at both ends of the cross-shaped latch 7 of each rod is used to lock and fix the corresponding cross-shaped latch 7 axially along each rod, preventing the cross-shaped latch 7 from sliding relative to each rod, which helps improve the stability and reliability of the device in this application.

[0025] This application provides a preferred embodiment, such as... Figure 2 As shown, the cross-shaped latch 7 includes a first latch 8 and a second latch 9, with the axial direction of the first latch 8 and the axial direction of the second latch 9 arranged perpendicularly. In this embodiment, the specific structure of the cross-shaped latch 7 is further defined. The cross-shaped latch 7 includes two latches, namely a first latch 8 and a second latch 9, with the axial directions of the first latch 8 and the second latch 9 arranged perpendicularly to each other; that is, the depth direction of the hole in the first latch 8 and the depth direction of the hole in the second latch 9 are perpendicular to each other. In one example, such as... Figure 1 As shown, the middle support rod 5 is arranged in the first clip 8 or the second clip 9, and the upper connecting rod 4 is arranged in the second clip 9 or the first clip 8, so that the support rod 5 and the connecting rod 4 are arranged vertically, thereby enabling one end of the support rod 5 to provide better support for the lining crack 2.

[0026] This application provides a preferred embodiment, such as... Figure 3As shown, the first latch 8 and the second latch 9 are adjustablely installed via a second bolt 10 and a second nut 11. This embodiment further defines the connection relationship between the first latch 8 and the second latch 9. By installing the first latch 8 and the second latch 9 with bolts and nuts, the axial angles of the first latch 8 and the second latch 9 can be adjusted according to the actual needs of the project during practical application, making the installation between the rods more stable. In one example, such as... Figure 1 As shown, when the installation angle between the anchor rod 1 and the connecting rod 4 on both sides is an acute angle or an obtuse angle, the second nut 11 can be rotated to unscrew the second bolt 10, thereby allowing the first buckle 8 and the second buckle 9 to rotate relative to each other to adjust the angle between the depth direction of the hole of the first buckle 8 and the depth direction of the hole of the second buckle 9, so as to suit the engineering needs; secondly, by designing the first buckle 8 and the second buckle 9 as a detachable bolt and nut structure, when any one of the buckles is worn, the damaged buckle can be replaced individually, which is beneficial to improving the economy and reliability of the device of this application.

[0027] This application provides a preferred embodiment in which one end of each of the two anchor rods 1 is fixedly installed to the lining 3 using adhesive. In this embodiment, the installation method of the anchor rods 1 and the lining 3 is further defined as follows: two holes are drilled in the lining 3, located on both sides of the lining crack 2, and the depth of the two holes extends into the interior of the tunnel soil. Two anchor rods 1 are then inserted into the two holes respectively, with the insertion ends of the anchor rods extending into the tunnel soil. Adhesive is then injected into the openings of the two holes to firmly fix the anchor rods within the holes.
