Description

Technical Field

[0001] The invention discloses a waterproof sealing structure for a basement cable casing, which is used for waterproof sealing of a basement cable casing and belongs to the technical field of sealing structures. Background Art

[0002] Casing waterproof sealing is a common construction technology, which can effectively prevent water penetration and leakage problems. In construction projects, casing waterproof sealing technology is widely used in various pipes, cables and lines through walls, ground and roofs to ensure the safety and stability of buildings. In the practice of casing waterproof sealing, you first need to select suitable materials, such as silicone sealant, polyurethane sealant polymer cement, etc., and then pre-treat the pipeline according to specific construction requirements, such as cleaning, rust removal, polishing, etc., then apply the sealing material around the pipeline or cable, compact and fix it, and finally fill and repair the sealing material to seal it.

[0003] There are also pipes passing through the walls in the basement. In order to prevent groundwater from seeping through the gaps between the pipes and the walls, although the above-mentioned sealing methods can also achieve a sealing effect, there are the following technical problems:

[0004] 1. The sealing material is not evenly applied, compacted and fixed properly, which may leave gaps or bubbles that affect the sealing effect;

[0005] 2. As time goes by, the sealing material may age and lose its elasticity, which may lead to a decrease in sealing effect. Utility Model Content

[0006] The purpose of the utility model is to provide a waterproof sealing structure for basement cable casings, which solves the problem in the prior art that the sealing material is unevenly applied, compacted and not fixed in place, and easily leaves gaps or bubbles that affect the sealing effect.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A waterproof sealing structure for a basement cable casing comprises a casing for passing a cable, an inner sealing structure arranged inside the casing to seal the gap between the casing and the cable, and an outer sealing structure arranged at both ends of the casing to seal the gap between the casing and the wall.

[0009] Furthermore, the inner sealing structure includes a limit plate arranged in the sleeve for allowing the cable to pass through, and a self-adhesive module sleeved on the cable and matched with the limit plate.

[0010] Furthermore, the limiting plate is provided with a plurality of through holes, which are located on one side of the end portion. An internal thread column A is provided on the limiting plate at the position of the through hole, which is located on the opposite side of the through hole 7, and the bottom of the internal thread column A is sealed;

[0011] The self-adhesive module includes two self-adhesive flexible rubber structures for clamping cables. The self-adhesive flexible rubber structure includes an arc-shaped clip, a through hole A and an internal thread column B arranged on the arc-shaped clip, and a flexible rubber with self-adhesive glue at both ends of the arc-shaped clip on one side of the internal thread column B. Corresponding to the positions of the internal thread column A and the internal thread column B, a through hole B is provided on the flexible rubber, the flexible rubber is sleeved on the internal thread column B, and the thread column B11 is not higher than the flexible rubber, and a bolt that cooperates with the internal thread column A8 is provided on the through hole A, the internal thread column B and the through hole B.

[0012] Furthermore, a first concrete layer and a waterproof layer A are sequentially arranged in the sleeves located at both ends of the self-adhesive module and the limiting plate.

[0013] Furthermore, the external sealing structure includes a first limiting plate, a second limiting plate and a third limiting plate which are sequentially arranged at intervals on both ends of the sleeve, the third limiting plate is located on one side of the end, a sealing gasket is provided on the sleeve between the first limiting plate and the second limiting plate, a waterproof grouting hole is provided on the third limiting plate, and a waterproof layer B formed by waterproof paint injected through the waterproof grouting hole is provided between the second limiting plate and the third limiting plate.

[0014] Furthermore, the diameters of the first limiting plate, the second limiting plate and the third limiting plate increase sequentially.

[0015] Furthermore, the sealing gasket has the same diameter as the second limiting plate and is sleeved on the outer edge of the first limiting plate.

[0016] Furthermore, a second concrete layer is provided on the waterproof layer A and the third limiting plate.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] First, the utility model provides an inner sealing structure to seal the gap between the casing and the cable inside the casing, which can ensure a more uniform seal and reduce the generation of gaps and bubbles. By providing an outer sealing structure at both ends of the casing to seal the gap between the casing and the wall, it can effectively prevent groundwater infiltration. The double-layer sealing design enhances the stability of the entire waterproof sealing structure, and can maintain good waterproof performance even in complex underground environments.

[0019] Second, the inner sealing structure of the present invention clamps the cable through the self-adhesive module and is placed in the casing to cooperate with the limiting disk. This not only facilitates the installation of the self-adhesive module to a suitable position, but also enables the self-adhesive module to cooperate with the limiting disk to evenly apply pressure around the cable, ensuring that the sealing material is evenly distributed and reducing the generation of gaps and bubbles.

[0020] 3. The self-adhesive module in the present invention is firmly fixed to the limit plate by bolts that cooperate with the through holes and internal threaded columns A on the limit plate, ensuring the accurate and stable position of the cable and preventing the cable from moving inside the casing. The flexible rubber is not easily aged and loses its elasticity over time, thus effectively avoiding the problem of reduced sealing effect.

[0021] Fourth, the first concrete layer in the present invention strengthens the structural strength and stability of the casing, enabling it to withstand external pressure and impact, protecting the internal cables and sealing structure from damage. The waterproof layer A cooperates with the self-adhesive module to play a dual role in preventing penetration of the casing.

[0022] 5. The outer sealing structure of the present invention is provided with multiple layers of limiting plates, and a sealing gasket is sleeved on the sleeve between the first limiting plate and the second limiting plate. The first limiting plate and the second limiting plate can clamp the sealing gasket and enable the sealing gasket to seal the gap between the wall and the sleeve. The waterproof layer B formed by grouting can effectively prevent moisture from penetrating through the gap between the sleeve and the wall, significantly improving the waterproof effect.

[0023] 6. The present invention provides that the diameters of the first limiting plate, the second limiting plate and the third limiting plate are increased in sequence, which not only increases the water seepage path but also facilitates the installation of the sealing gasket and the waterproof layer B;

[0024] 7. The utility model defines that the sealing gasket has the same diameter as the second limiting plate and is sleeved on the outer edge of the first limiting plate to ensure that the sealing gasket can be accurately sleeved on the outer edge of the first limiting plate, achieving a good sealing effect;

[0025] 8. The utility model is provided with a second concrete layer on the waterproof layer A and the third limiting plate, so as to facilitate the basement cable casing waterproof sealing structure to form an integral whole with the wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Example 1

[0041] In order to solve the problem that the existing technology causes uneven application of sealing materials, insufficient compaction and fixation, which may leave gaps or bubbles and affect the sealing effect. Figure 1-5 As shown, a waterproof sealing structure for a basement cable casing is provided, comprising a casing 1 for passing a cable, an inner sealing structure 3 arranged inside the casing 1 to seal the gap between the casing 1 and the cable 2, and an outer sealing structure 4 arranged at both ends of the casing 1 to seal the gap between the casing 1 and the wall.

[0042] In practice, the casing is installed on the wall, and the cable installed in the casing is sealed between the cable and the casing through the inner sealing casing 1, and the gap between the casing and the wall is sealed by the outer sealing structure 4. In this embodiment, by providing an inner sealing structure to seal the gap between the casing and the cable within the casing, it can ensure a more uniform seal and reduce the generation of gaps and bubbles. By providing outer sealing structures at both ends of the casing to seal the gap between the casing and the wall, it can effectively prevent groundwater infiltration. The double-layer sealing design enhances the stability of the entire waterproof sealing structure, and can maintain good waterproof performance even in complex underground environments.

[0043] Example 2

[0044] Based on Example 1, the inner sealing structure 3 includes a limit plate 5 disposed within the casing 1 to allow the cable to pass through, and a self-adhesive module 6 that is mounted on the cable 2 and cooperates with the limit plate 5. The inner sealing structure utilizes the self-adhesive module to clamp the cable and then be placed within the casing, where it cooperates with the limit plate. This not only facilitates the installation of the self-adhesive module in the appropriate position, but also allows the self-adhesive module and the limit plate to cooperate to evenly apply pressure around the cable, ensuring uniform distribution of the sealing material and reducing the generation of gaps and bubbles.

[0045] Example 3

[0046] On the basis of Example 2, the limit plate 5 is provided with multiple through holes 7, which are located on one side of the end. An internal threaded column A8 is provided on the limit plate 5 at the position of the through hole 7, which is located on the opposite side of the through hole 7, and the bottom of the internal threaded column A8 is sealed; the self-adhesive module 6 includes two self-adhesive flexible rubber structures 9 for clamping the cable 2, and the self-adhesive flexible rubber structure 9 includes an arc-shaped clip 10, a through hole A24 and an internal threaded column B11 provided on the arc-shaped clip 10, and a flexible rubber 12 with self-adhesive glue at both ends of the arc-shaped clip 10 provided on one side of the internal threaded column B11. Corresponding to the positions of the internal threaded column A8 and the internal threaded column B11, a through hole B13 is provided on the flexible rubber 12, and the flexible rubber 12 is sleeved on the internal threaded column B11, and the threaded column B11 is not higher than the flexible rubber 12 (such as 0.5cm-2cm lower), and the through hole A24, the internal threaded column B11 and the through hole B13 are provided with bolts 14 that match the internal threaded column A8.

[0047] In practice, the cable is clamped between the two self-adhesive flexible rubber structures 9 and secured together by the self-adhesive adhesive at both ends of the two self-adhesive flexible rubber structures 9. The structures are then placed within the casing and secured by bolts engaging with the through-holes A24, the internally threaded studs B11, and the through-holes B13, and then engaging with the internally threaded studs A8. Because the threaded studs B11 do not extend above the flexible rubber 12, the bolts 14 engaging with the internally threaded studs A8 press the flexible rubber 12 against the limit plate 5, the inner wall of the casing, and the cable, effectively preventing leakage from occurring at the hole through which the cable passes and at the position where the cable engages with the casing. The self-adhesive module in this embodiment is securely secured to the limit plate by bolts engaging with the through-holes and internally threaded studs A on the limit plate, ensuring accurate and stable cable positioning and preventing movement within the casing. Furthermore, the flexible rubber is less susceptible to aging and loss of elasticity over time, effectively preventing a decrease in sealing effectiveness.

[0048] Example 4

[0049] Based on Example 3, a first concrete layer 15 and a waterproof layer A16 are sequentially provided in the casing 1 at both ends of the self-adhesive module 6 and the limiting plate 5. The first concrete layer strengthens the structural strength and stability of the casing, enabling it to withstand external pressure and impact, and protect the internal cables and sealing structure from damage. The waterproof layer A cooperates with the self-adhesive module to play a dual role in preventing penetration of the casing.

[0050] Example 5

[0051] On the basis of Example 4, the outer sealing structure 4 includes a first limiting plate 17, a second limiting plate 18, and a third limiting plate 19, which are sequentially spaced apart on both ends of the sleeve 1. The third limiting plate 19 is located on one side of the end. A sealing gasket 20 is provided on the sleeve 1 between the first limiting plate 17 and the second limiting plate 18. A waterproof grouting hole 21 is provided on the third limiting plate 19. A waterproof layer B22 formed by injecting waterproof paint through the waterproof grouting hole 21 is provided between the second limiting plate 18 and the third limiting plate 19. The outer sealing structure is provided with multiple layers of limiting plates, and a sealing gasket is provided on the sleeve between the first limiting plate and the second limiting plate. The first limiting plate and the second limiting plate can clamp the sealing gasket and enable the sealing gasket to seal the gap between the wall and the sleeve. The waterproof layer B formed by grouting can effectively block moisture from penetrating through the gap between the sleeve and the wall, significantly improving the waterproof effect.

[0052] Example 6

[0053] Based on Example 5, the diameters of the first, second, and third limiting plates 17, 18, and 19 are sequentially increased. The diameters of the limiting plates are set according to actual needs. This sequential increase in the diameters of the first, second, and third limiting plates not only increases the water seepage path but also facilitates the installation of the sealing gasket and waterproof layer B.

[0054] Example 7

[0055] Based on Example 6, the sealing gasket 20 has the same diameter as the second limiting plate 18 and is mounted on the outer edge of the first limiting plate 17 to ensure that the sealing gasket can be accurately mounted on the outer edge of the first limiting plate, thereby achieving a good sealing effect.

[0056] Example 8

[0057] Based on Example 6, a second concrete layer 23 is provided on the waterproof layer A16 and the third limiting plate 19. The second concrete layer is provided on the waterproof layer A and the third limiting plate to facilitate the basement cable casing waterproof sealing structure to form an integral whole with the wall.
