Description

Technical Field

[0001] This utility model belongs to the field of highway slope technology, and in particular relates to geomembrane anti-seepage highway slope protection. Background Technology

[0002] Slope geomembrane seepage control is an engineering technique that uses high-polymer geomembranes (such as HDPE membranes, composite geomembranes, etc.) to block the seepage path of slopes, preventing soil erosion, landslides, and groundwater pollution. The top of the slope geomembrane is mostly fixed with fixing nails or plastic anchor nails. By digging a trench at the top of the slope, the edge of the geomembrane is laid inside the trench, and the edge of the geomembrane is fixed with fixing nails. Then the trench is filled in, burying the edge of the geomembrane and the fixing nails inside the trench, which enhances the stability of the buried part of the geomembrane.

[0003] Geomembranes are often used for seepage prevention on highway slopes. When geomembranes are in use, the tensile force generated by slope deformation and water flow impact can pull out the fixing nails at the top of the geomembrane, leading to slippage at the top of the geomembrane. Therefore, geomembranes are needed for seepage prevention on highway slopes. The top of the geomembrane can be fixed by a fixing structure to prevent slippage and ensure the firmness of the geomembrane installation. Utility Model Content

[0004] The purpose of this utility model is to provide a geomembrane-based anti-seepage highway slope protection system, which can fix the top of the geomembrane through a fixing structure to prevent slippage of the top of the geomembrane and ensure the firmness of the geomembrane laying, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a geomembrane seepage-proof highway slope protection, which includes a first set of multiple rows of fixing nails that penetrate through the slope surface. The slope surface is covered with a protective membrane. The surface of the protective membrane is provided with multiple rows of identical fixing plates. The first set of fixing nails penetrates the fixing plates and the protective membrane and is fixedly connected to the slope. The top of the fixing plate is fixedly connected with two symmetrical sliding sleeves. The surface of the sliding sleeve is fixedly connected with a threaded sleeve. The inner cavity of the threaded sleeve is threadedly connected with a threaded rod. The end of the threaded rod away from the sliding sleeve is fixedly connected with a torsion block. The inner cavity of the sliding sleeve is slidably connected with a second set of fixing nails. The threaded rod penetrates into the inner cavity of the sliding sleeve and fits against the second set of fixing nails. The surface of the second set of fixing nails is fixedly connected with a handle.

[0006] Preferably, the fixing nail includes a nail body that penetrates the fixing plate, a limit ring is fixedly connected to the surface of the nail body, and two symmetrical connecting rods are fixedly connected to the surface of the nail body.

[0007] Preferably, the surface of the fixing plate is fixedly connected to two symmetrical connecting plates, and the bottom of the connecting plates is fixedly connected to two rows of symmetrical nail heads.

[0008] Preferably, the limiting ring is located at the top of the fixed plate, the sliding sleeve is in an inclined state, and two symmetrical torsion bars are fixedly connected to the surface of the torsion block.

[0009] Preferably, the second fixing nail is adapted to the sliding sleeve, the bottom of the connecting plate is in contact with the protective film, and the nail head is in contact with the protective film.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model places a fixing plate on top of the protective membrane, with fixing nail one passing through the fixing plate and the protective membrane and being fixedly connected to the slope, and fixing nail two passing through the sliding sleeve and the protective membrane and being fixedly connected to the slope. Rotating the torsion block causes the threaded rod and the threaded sleeve to move threadedly, so that the threaded rod passes through the inner cavity of the sliding sleeve and fits against the nail body. This achieves the goal of fixing the top of the geomembrane through the fixing structure, preventing the top of the geomembrane from slipping and ensuring the firmness of the geomembrane laying.

[0012] 2. By using the connecting plate and nail head together, when the fixing plate fixes the protective film, the connecting plate will fix the top of the protective film with the nail head, which expands the contact area between the fixing plate and the protective film, avoids the contact between the fixing plate and the protective film being too small, and ensures the firmness of the fixing plate.

[0020] Figure 1-5This invention illustrates an embodiment of a geomembrane-based seepage-proof highway slope protection system, comprising multiple rows of fixing nails 2 penetrating the surface of a slope 1. A protective membrane 3 is laid on the surface of the slope 1, and multiple rows of identical fixing plates 4 are disposed on the surface of the protective membrane 3. Two symmetrical connecting plates 11 are fixedly connected to the surface of the fixing plates 4, and two rows of symmetrical nail heads 12 are fixedly connected to the bottom of the connecting plates 11. The fixing nails 2 penetrate the fixing plates 4 and the protective membrane 3 and are fixedly connected to the slope 1. Two symmetrical sliding sleeves 5 are fixedly connected to the top of the fixing plates 4, and threaded sleeves 6 are fixedly connected to the surface of the sliding sleeves 5. Threaded rods 7 are threadedly connected to the inner cavity of the threaded sleeves 6, with one end of the threaded rods 7 away from the sliding sleeves 5. The fixed connection includes a torsion block 8, and the inner cavity of the sliding sleeve 5 is slidably connected to a fixing nail 9. The fixing nail 9 is adapted to the sliding sleeve 5. The bottom of the connecting plate 11 is in contact with the protective film 3, and the nail head 12 is in contact with the protective film 3. Through the cooperation of the connecting plate 11 and the nail head 12, when the fixed plate 4 fixes the protective film 3, the connecting plate 11 will fix the top of the protective film 3 through the nail head 12, thereby increasing the contact area between the fixed plate 4 and the protective film 3 and avoiding the contact area between the fixed plate 4 and the protective film 3 being too small, thus ensuring the firmness of the fixed plate 4. The threaded rod 7 penetrates into the inner cavity of the sliding sleeve 5 and is in contact with the fixing nail 9. The surface of the fixing nail 9 is fixedly connected to a handle 10. Example 2

[0021] Figure 1-5 This invention illustrates an embodiment of a geomembrane-based seepage-proof highway slope protection system, comprising multiple rows of fixing nails 2 penetrating the surface of a slope 1. Each fixing nail 2 includes a nail body 21 penetrating a fixing plate 4. A limiting ring 22 is fixedly connected to the surface of the nail body 21, and two symmetrical connecting rods 23 are fixedly connected to the surface of the nail body 21. The limiting ring 22 is located at the top of the fixing plate 4. The sliding sleeve 5 is in an inclined state. Two symmetrical torsion bars are fixedly connected to the surface of the torsion block 8. A protective membrane 3 is laid on the surface of the slope 1, and multiple rows of identical fixing plates 4 are arranged on the surface of the protective membrane 3. The fixing nails 2 penetrate the fixing plates 4 and the protective membrane 3 and are fixedly connected to the slope 1. Two symmetrical sliding sleeves 5 are fixedly connected to the top of the fixing plate 4. A threaded sleeve 6 is fixedly connected to the surface of the sliding sleeve 5. A threaded rod 7 is threadedly connected to the inner cavity of the threaded sleeve 6. A torsion block 8 is fixedly connected to the end of the threaded rod 7 away from the sliding sleeve 5. A second fixing nail 9 is slidably connected to the inner cavity of the sliding sleeve 5. The threaded rod 7 penetrates into the inner cavity of the sliding sleeve 5 and fits against the second fixing nail 9. A handle 10 is fixedly connected to the surface of the second fixing nail 9.

[0022] Working principle: When using this utility model, the user places the fixing plate 4 on top of the protective membrane 3, so that the fixing nail 2 passes through the fixing plate 4 and the protective membrane 3 and is fixedly connected to the slope 1, and the fixing nail 9 passes through the sliding sleeve 5 and the protective membrane 3 and is fixedly connected to the slope 1. Rotating the torsion block 8 causes the threaded rod 7 and the threaded sleeve 6 to move threadedly, so that the threaded rod 7 passes through the inner cavity of the sliding sleeve 5 and fits against the nail body 21. At this time, the two symmetrical fixing nails 9 will be open and limit the fixing plate 4, so that the fixing plate 4 fixes the protective membrane 3, preventing the top of the geomembrane from slipping and ensuring the firmness of the geomembrane laying. When the fixing plate 4 fixes the protective membrane 3, the connecting plate 11 will fix the top of the protective membrane 3 through the nail head 12, expanding the contact area between the fixing plate 4 and the protective membrane 3, avoiding the contact area between the fixing plate 4 and the protective membrane 3 being too small, and ensuring the firmness of the fixing plate 4.

[0023] In summary, this geomembrane anti-seepage highway slope protection works by placing the fixing plate 4 on top of the protective membrane 3, allowing the fixing nail 2 to penetrate the fixing plate 4 and the protective membrane 3 and be fixedly connected to the slope 1, and allowing the fixing nail 9 to pass through the sliding sleeve 5 and the protective membrane 3 and be fixedly connected to the slope 1. By rotating the torsion block 8, the threaded rod 7 and the threaded sleeve 6 move threadedly, allowing the threaded rod 7 to penetrate into the inner cavity of the sliding sleeve 5 and fit against the nail body 21. This achieves the goal of fixing the top of the geomembrane through the fixing structure, preventing the top of the geomembrane from slipping and ensuring the firmness of the geomembrane installation.
