Abstract
Description
Technical Field
[0001] This utility model relates to the field of tunnel drainage blind pipe installation technology, specifically a tunnel drainage blind pipe installation structure. Background Technology
[0002] The working principle of blind drainage pipes in tunnels is that fissure water in the tunnel rock mass seeps down through the gaps between the geotextile behind the waterproofing liner and the tunnel's initial support face, eventually reaching the blind drainage pipes and being discharged into the tunnel's drainage ditch. The purpose is to drain fissure water behind the tunnel lining, preventing water accumulation and ensuring timely drainage. This prevents water from accumulating behind the lining, which could damage the lining structure, cause cracks, ultimately lead to tunnel leakage, and even endanger structural safety, resulting in a safety accident.
[0003] The existing tunnel drainage blind pipes are not easy to anchor during installation, resulting in insufficient installation stability and a tendency to shift or float, which affects the drainage process.
[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a tunnel drainage blind pipe installation structure. Utility Model Content
[0005] The purpose of this utility model is to provide a tunnel drainage blind pipe installation structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a tunnel drainage blind pipe installation structure, comprising a support positioning component, a blind pipe body, and an anchoring component. The blind pipe body is disposed in the middle of the support positioning component, and the support positioning component includes a support upper frame, a support lower frame, and ear plates. The support lower frame is installed below the support upper frame, and ear plates are fixed on both sides of the support upper frame and the support lower frame. An anchoring component is disposed on the upper side of the ear plates, and the anchoring component includes a connecting plate, a threaded cylinder, a threaded rod, and anchoring nails. A threaded cylinder is embedded in one side of the connecting plate, and a threaded rod is installed inside the threaded cylinder, and anchoring nails are fixed on the lower side of the threaded rod.
[0007] Furthermore, the support positioning component also includes a rubber layer, and both the upper support frame and the lower support frame have a semi-circular structure, with a rubber layer bonded to the inner surfaces of both the upper support frame and the lower support frame.
[0008] Furthermore, the support and positioning component also includes an airbag layer, an anti-slip layer, and an inflation nozzle. The airbag layer is provided on the inner side of the rubber layer, and the anti-slip layer is provided on the inner side of the airbag layer. An inflation nozzle is installed on one side of the airbag layer.
[0009] Furthermore, the ear plates and connecting plates on both sides of the upper and lower support frames are all connected by connecting bolts, and there are two sets of connecting plates and anchor nails.
[0010] Furthermore, an arc-shaped base is fixed to the lower side of the supporting frame, and an angle adjustment component is installed below the arc-shaped base, with a base plate provided below the angle adjustment component.
[0011] Furthermore, the angle adjustment assembly includes a support plate, a rotating shaft, and a rotating block. The support plate is fixedly connected to the base plate, and the rotating block is rotatably mounted on the inner side of the support plate via the rotating shaft.
[0012] Furthermore, the angle adjustment assembly also includes a side plate and a locking bolt. Both ends of the rotating shaft pass through the side plate and are rotatably connected to the side plate. The outer end of the rotating shaft is fixed with the side plate, and the outer side of the side plate is fitted with a locking bolt.
[0013] Furthermore, the upper side of the rotating block is fixedly connected to the arc-shaped base through a connecting block, and the center line of the arc-shaped base coincides with the center line of the supporting lower frame.
[0014] This utility model provides a tunnel drainage blind pipe installation structure, which has the following beneficial effects:
[0015] This utility model is equipped with an anchoring component. The connecting bolts facilitate the simultaneous locking of the connecting plate and the ear plates on both sides of the upper and lower supporting frames, thereby achieving the assembly connection between the connecting plate, the upper supporting frame, and the lower supporting frame. By rotating the threaded rod inside the threaded cylinder, the depth of the lower anchoring nail can be adjusted, allowing the anchoring nail to be buried in the tunnel soil layer. This improves the stability of the blind pipe body and the support positioning component installation, ensuring the tunnel drainage effect.
[0016] This utility model is equipped with an angle adjustment component. The main body of the blind pipe can be installed inside the support frame formed by the upper support frame and the lower support frame. The angle of the arc-shaped base can be adjusted by rotating the pivot and the pivot block, thereby adjusting the tilt angle of the support positioning component and the main body of the blind pipe to meet the needs of tunnel drainage. During the rotation of the pivot, the side plate rotates synchronously. After the angle is adjusted, the side plate can be fixed to the support plate by locking bolts passing through the side plate, so that the adjusted pivot block and the arc-shaped base remain stable, thereby ensuring the stable installation of the main body of the blind pipe with different tilt angles.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0022] like Figures 1-2 As shown, a tunnel drainage blind pipe installation structure includes a support and positioning component 1, a blind pipe body 2, and an anchoring component 3.

An inflation nozzle 107 is installed on one side of the airbag layer 105. The blind tube body 2 can be installed inside the support frame formed by the upper support frame 101 and the lower support frame 102. The anti-slip layer 106 is attached to the outer side of the blind tube body 2 to play an anti-slip role. The airbag layer 105 can be inflated through the inflation nozzle 107 and the external inflation device, so that the airbag layer 105 can expand or deflate and contract. It is suitable for blind tube bodies 2 of different sizes.
[0023] like Figures 1-2As shown, an anchoring assembly 3 is provided on the upper side of the ear plate 103. The anchoring assembly 3 includes a connecting plate 301, a threaded cylinder 302, a threaded rod 303, and an anchoring nail 304. The threaded cylinder 302 is embedded in one side of the connecting plate 301, and the threaded rod 303 is installed inside the threaded cylinder 302. An anchoring nail 304 is fixed to the lower side of the threaded rod 303. Connecting bolts 4 pass through the ear plates 103 and connecting plates 301 on both sides of the upper frame 101 and the lower frame 102. The connecting plate 301 and the anchoring nail 304 are connected by bolts. Two sets are provided; the connecting bolts 4 facilitate the simultaneous locking of the connecting plate 301 and the ear plates 103 on both sides of the upper support frame 101 and the lower support frame 102, so as to realize the assembly connection between the connecting plate 301, the upper support frame 101, and the lower support frame 102. By rotating the threaded rod 303 inside the threaded cylinder 302, the depth of the lower anchor nail 304 can be adjusted, so that the anchor nail 304 can be buried in the tunnel soil layer, thereby improving the stability of the blind pipe body 2 and the support positioning component 1 and ensuring the tunnel drainage effect.
[0024] like Figure 1 and Figure 3 As shown, an arc-shaped base 5 is fixed to the lower side of the supporting frame 102, and an angle adjustment component 7 is installed below the arc-shaped base 5. A base plate 6 is provided below the angle adjustment component 7. The angle adjustment component 7 includes a support plate 701, a rotating shaft 702, and a rotating block 703. The support plate 701 is fixedly connected to the base plate 6, and the rotating block 703 is rotatably installed on the inner side of the support plate 701 through the rotating shaft 702. The angle adjustment component 7 also includes a side plate 704 and a locking bolt 705. Both ends of the rotating shaft 702 pass through the side plate 704 and are rotatably connected to the side plate 704. The outer end of the rotating shaft 702 is fixed to the side plate 704, and the locking bolt 705 is installed on the outer side of the side plate 704. 05. The upper side of the rotating block 703 is fixedly connected to the arc-shaped base 5 through the connecting block, and the center line of the arc-shaped base 5 coincides with the center line of the supporting lower frame 102. The angle of the arc-shaped base 5 can be adjusted by rotating the rotating shaft 702 and the rotating block 703, thereby adjusting the tilt angle of the supporting positioning component 1 and the blind pipe body 2 to meet the tunnel drainage requirements. During the rotation of the rotating shaft 702, the side plate 704 rotates synchronously. After the angle is adjusted, the side plate 704 can be fixed to the bracket plate 701 by passing through the locking bolt 705, so that the adjusted rotating block 703 and the arc-shaped base 5 remain stable, thereby ensuring the stable layout of the blind pipe body 2 with different tilt angles.
[0025] In summary, as Figures 1-3As shown, the tunnel drainage blind pipe installation structure can be used by first installing a support upper frame 101 and a support lower frame 102 on the outside of the blind pipe body 2. The airbag layer 105 can be inflated by the air inlet 107 and the external inflation device, so that the airbag layer 105 can expand and is suitable for blind pipe bodies 2 of different sizes. This allows the anti-slip layer 106 to fit tightly against the outer side of the blind pipe body 2 to play an anti-slip role. Then, the connecting plate 301 and the ear plates 103 on both sides of the support upper frame 101 and the support lower frame 102 are locked simultaneously by the connecting bolts 4 to realize the assembly connection between the connecting plate 301 and the support upper frame 101 and the support lower frame 102.
[0026] Then, the angle of the arc-shaped base 5 can be adjusted by rotating the pivot 702 and the pivot block 703, thereby adjusting the tilt angle of the support positioning component 1 and the blind pipe body 2. After the angle is adjusted, the side plate 704 can be fixed to the bracket plate 701 by passing the locking bolt 705 through the side plate 704, so that the adjusted pivot block 703 and the arc-shaped base 5 remain stable, thereby ensuring the stable installation of the blind pipe body 2 with different tilt angles. Then, the depth of the lower anchor nail 304 can be adjusted by rotating the threaded rod 303 inside the threaded cylinder 302, so that the anchor nail 304 can be buried in the tunnel rock and soil layer, thereby improving the stability of the blind pipe body 2 and the support positioning component 1 installation and ensuring the tunnel drainage effect. This completes the usage process of the tunnel drainage blind pipe installation structure.
