Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and more specifically, it relates to a water-stopping and seepage-proof structure for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluices, and fish passages, to achieve their objectives. During the construction of water conservancy projects, it is often necessary to install water-stopping and seepage-proof structures on the slopes of the dam body to facilitate construction and prevent cracks and holes from appearing in the dam itself.

[0003] Most existing water-stopping and seepage-proof structures in water conservancy projects are inconvenient to install and fix, and after installation and fixation, they may loosen, resulting in poor water-stopping and seepage-proof effects. Furthermore, the water-stopping and seepage-proofing mechanism of the geomembrane alone is not effective. In order to ensure the long-term use of the geomembrane and its anti-corrosion effect, a geomembrane is usually laid on the surface of the geomembrane. However, it is difficult to lay the membrane neatly by visual inspection alone. When it is skewed, it will affect the water-stopping and seepage-proofing effect. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a water-stopping and seepage-proof structure for water conservancy engineering construction, comprising a slope, an anti-seepage plate provided on the outer side of the slope, inserts fixedly provided on the inner wall of the anti-seepage plate at each of the four corners, slots corresponding to each of the slope, inserts located inside the slots, receiving grooves provided inside each insert, baffles fixedly provided inside the receiving grooves at the middle position, threaded rods rotatably provided on both sides of the baffles, sliding blocks slidably provided inside the receiving grooves on both sides of the baffles, a pointed cone fixedly provided on one side of each moving block, one end of each pointed cone extending through the inserts into the interior of the slope, threaded rods threadedly connected to each moving block, a turning block fixedly provided at one end of each threaded rod, a roller provided above the slope, and limit devices provided below the rollers on both sides of the anti-seepage plate.

[0006] The present invention is further configured such that the limiting device includes a vertical plate, two sets of which are located on the left and right sides of the seepage-proof plate, a top plate is fixedly provided on the upper end surface of each vertical plate, and threaded holes are provided on each top plate. Multiple threaded holes are provided and arranged along the length direction of the top plate. The vertical plate and the top plate are arranged in an L-shape.

[0008] The present invention is further configured such that a support plate is fixedly provided on the upper end surface and on both sides of the seepage-proof plate, and a T-shaped groove is provided on the inner wall of the support plate.

[0012] The present invention is further configured such that each of the moving blocks is provided with a support spring on its outer wall, and the other end of the support spring is fixedly connected to the baffle.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides a water-stopping and seepage-proof structure for water conservancy engineering construction, which has the following beneficial effects: 1. By setting up a seepage barrier, insert block, movable block and cone, the user can rotate the screw to move the movable block and cone outward, so that they pass through the insert block and enter the slope, thereby achieving the effect of fixing the slope and seepage barrier and preventing loosening.

[0014] 2. By setting up a roller, upright plate, top plate, and pressure block, the user can pull the geomembrane from the outside of the roller so that both sides of the geomembrane contact the inner wall of the upright plate, thereby achieving the effect of limiting and measuring it to prevent it from tilting after installation. Then, the turntable is rotated to move the pressure block downward so that the pressure block presses and fixes the geomembrane on the geomembrane plate, which facilitates the increase of the water-stopping and seepage prevention effect.

[0015] 3. By setting up a support plate, T-block, and hand-tightening screw, the user can unscrew one end of the hand-tightening screw to open the mounting hole. At this point, the T-block can be removed from the inside of the T-slot to separate the roll and support plate, thus facilitating the disassembly and replacement of the geomembrane.

[0021] Please see Figure 1-7 A water-stopping and seepage-proof structure for water conservancy engineering construction includes a slope 1, an anti-seepage plate 2 on the outer side of the slope 1, insert blocks 3 fixed on the inner wall of the anti-seepage plate 2 at the four corners, slots 4 correspondingly opened on the slope 1, insert blocks 3 located inside the slots 4, receiving grooves 5 opened inside the insert blocks 3, baffles 6 fixed inside the receiving grooves 5 at the middle position, threaded rods 7 rotatably installed on both sides of the baffles 6, sliding blocks 8 slidably installed inside the receiving grooves 5 at both sides of the baffles 6, a pointed cone 9 fixed on one side of each moving block 8, one end of each pointed cone 9 extending through the insert blocks 3 into the interior of the slope 1, threaded rods 7 threadedly connected to moving blocks 8, a turning block 10 fixed on one end of each threaded rod 7, a roller 11 above the slope 1, limit devices installed below the roller 11 at both sides of the anti-seepage plate 2, and a waterproof layer 24 at the contact position between the slope 1 and the anti-seepage plate 2.

[0022] In this embodiment, the limiting device includes a vertical plate 12. Two sets of vertical plates 12 are provided, both located on the left and right sides of the impermeable plate 2. A top plate 13 is fixedly provided on the upper surface of each vertical plate 12. Threaded holes 14 are provided on each top plate 13. Multiple threaded holes 14 are provided and arranged along the length direction of the top plate 13. The vertical plate 12 and the top plate 13 are arranged in an L-shape. Threaded posts 15 are provided inside each threaded hole 14. The bottom of each threaded post 15 passes through the threaded hole 14 and is rotatably provided with a pressure block 16. A turntable 17 is fixedly provided at the upper end of each. Anti-slip pads 25 are provided at the bottom of each pressure block 16.

[0023] More specifically, the user can rotate the screw 7 to move the moving block 8 and the cone 9 outward, so that they pass through the insert block 3 and enter the slope 1, thereby fixing the slope 1 and the geomembrane 2 to prevent loosening. Then, the user can pull the geomembrane from the outside of the roller 11 so that the two sides of the geomembrane contact the inner wall of the vertical plate 12, thereby limiting and measuring it to prevent it from tilting after installation. Then, the user can rotate the turntable 17 to move the pressure block 16 downward, so that the pressure block 16 presses and fixes the geomembrane on the geomembrane 2, which can increase the water-stopping and seepage prevention effect.

[0024] Please see Figure 1 , Figure 4 and Figure 6As an embodiment for fixing the geomembrane: support plates 18 are fixedly provided on the upper end face and both sides of the geomembrane 2. T-slots 19 are provided on the inner wall of the support plates 18. T-blocks 20 are fixedly provided at both ends of the roller 11. The T-blocks 20 are slidably installed inside the T-slots 19. Connection holes 21 are provided on the outer wall of the support plates 18. Mounting holes 22 are provided on the outer wall of the T-blocks 20. Hand screws 23 are provided inside the connection holes 21 and the mounting holes 22.

[0025] Specifically, the user can unscrew one end of the hand screw 23 out of the mounting hole 22, and then remove the T-block 20 from the inside of the T-slot 19 to separate the roll 11 and the support plate 18, thereby facilitating the disassembly and replacement of the geomembrane.

[0026] Please refer to Figure 5 As a further embodiment of giving the moving block 8 an outward thrust: each of the moving blocks 8 is provided with a support spring 26, and the other end of the support spring 26 is fixedly connected to the baffle 6.

[0027] Specifically, the support spring 26 can provide an outward pushing force to the moving block 8 so that the cone 8 can penetrate the slope 1 with less effort.

[0028] In summary, when using the entire equipment: the user can insert the insert block 3 at the bottom of the geomembrane 2 into the slot 4 above the slope 1, and then rotate the screw 7 by turning the block 10 to move the moving block 8 and the cone 9 outward, so that they pass through the insert block 3 and enter the slope 1, thereby fixing the slope 1 and the geomembrane 2 and preventing them from falling off. Afterward, the user can pull the geomembrane on the roller 11 from its outside so that the two sides of the geomembrane contact the inner wall of the vertical plate 12, thereby achieving the purpose of fixing the geomembrane. The limiting and measuring effects prevent it from tilting after installation. Then, the turntable 17 is rotated to move the pressure block 16 downward so that the pressure block 16 presses and fixes the geomembrane on the geomembrane plate 2, thereby further increasing the water-stopping and seepage-proofing effect. When the geomembrane needs to be replaced, one end of the hand screw 23 can be unscrewed out of the mounting hole 22 by removing it. At this time, the T-block 20 can be taken out from the inside of the T-slot 19 to separate the roller 11 and the support plate 18, thereby facilitating the disassembly and replacement of the geomembrane.
