Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of construction anti-seepage structures, and in particular relates to an anti-seepage structure for water conservancy project construction. Background Art
[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. Water is an indispensable and precious resource for human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet the needs of people's life and production for water resources. However, due to the seepage damage of the dam, the dam is in danger. The seepage damage of the dam can be divided into three situations. The first one is due to the improper structure of the dam itself. The first is the appearance of cracks and holes in the dam body, which causes seepage and slope collapse of the dam. The second is the unreasonable anti-seepage structure of the dam retaining surface, which causes long-term contact corrosion and leads to dam leakage. The third is the strong permeability of the sand layer and sandy loam layer at the dam foundation, which leads to poor anti-seepage ability of the dam. Most of the existing rubber anti-seepage parts are rubber bodies and concrete cast to form an isolation layer. However, in actual applications, we have found that many dams, canals and other projects have seepage in deformation joints. The reason is that the anti-seepage measures have not played a better role in anti-seepage.
[0003] After searching, the patent with authorization publication number CN216765771U discloses an environmentally friendly water conservancy project anti-seepage wall, including a dam body, a high-strength concrete layer is arranged on the inclined surface inside the dam body; two anti-seepage walls are fixedly installed inside the dam body, a gap is formed between the two anti-seepage walls, a buffer layer is arranged inside the gap, and protective layers are arranged on the outsides of the two anti-seepage walls.
[0004] The above patent has the following deficiencies: although the application sets a buffer layer, the buffer layer is set inside the dam body, the inclined surface of the dam body will still be impacted by the water flow, and there is no buffering for the wall outside the dam body. Long-term use will still reduce the service life of the dam body. Utility Model Content
[0005] The utility model aims to provide an anti-seepage structure for water conservancy project construction to solve the problems raised in the above-mentioned background technology.

[0016] Compared with the prior art, the beneficial effects of the utility model are:
[0017] (1) The utility model forms a complete anti-seepage structure for water conservancy project construction by arranging a reinforcement layer, an isolation layer, a drainage layer and an anti-seepage layer on the water-facing surface of the dam body, and by structural coordination between the layers. The anti-seepage structure is laid on the outside of the main structure of the water conservancy project to ensure that the layers are tightly connected and well fixed to form an effective waterproof barrier.

[0018] (2) The utility model achieves buffering of the dam structure by arranging a movable water-facing plate on the outer side of the dam body, and by the cooperation of the water-facing plate, the buffer plate and the spring damper.

[0019] (3) The utility model sets a frame on one side of the dam body and sets a movable sponge board inside the frame. Once water seeps into the frame, the water will be absorbed by the sponge board and stored inside the sponge board to prevent further water penetration.

The frame cover can be opened and locked by the cooperation of the threaded rod and the threaded hole, making it convenient to replace the new sponge board. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] See also Figure 1 - Figure 3 As shown, a water conservancy project construction anti-seepage structure includes:
[0028] The dam body 1 has a reinforcement layer 11 disposed on one side of the inclined surface of the dam body 1, an isolation layer 12 disposed on the side of the reinforcement layer 11 away from the dam body 1, a drainage layer 13 disposed on the side of the isolation layer 12 away from the reinforcement layer 11, and an anti-seepage layer 14 disposed on the side of the drainage layer 13 away from the isolation layer 12;
[0029] The water absorption structure 2 is arranged on one side of the anti-seepage layer 14. The water absorption structure 2 includes a frame 21 fixedly installed on one side of the anti-seepage layer 14, a sponge board 22 is movably installed inside the frame 21, and a frame cover 23 is movably installed on one side of the top of the frame 21;
[0030] The buffer structure 3 is arranged on one side of the frame 21. The buffer structure 3 includes two buffer boxes 31 fixedly installed on one side of the frame 21. Buffer plates 32 are movably installed inside the two buffer boxes 31. Several spring dampers 33 are connected between the buffer plates 32 and the inner walls of the buffer boxes 31. Water-receiving plates 34 are connected between the buffer plates 32.
[0031] Specifically, a fixed plate 24 is symmetrically installed on one side of the frame body 21 close to the frame cover 23, and a threaded hole 25 is opened at the center of the fixed plate 24. A movable plate 26 is symmetrically installed on the side of the frame cover 23 close to the frame body 21. A U-shaped plate 27 is fixedly installed on the side of the movable plate 26 away from the fixed plate 24. A threaded rod 28 is installed inside the U-shaped plate 27 through threaded engagement. A through hole 29 is opened at the center of the movable plate 26. The through hole 29 is correspondingly arranged with the threaded rod 28, and the threaded rod 28 is correspondingly arranged with the threaded hole 25. The threaded rod 28 is threadedly engaged with the inner thread of the threaded hole 25.
[0032] As can be seen from the above, the reinforcement layer 11 is used to enhance the bearing capacity and stability of the dam body 1. The reinforcement layer 11 adopts high-strength materials, such as steel bars, steel plates, etc., and is connected to the dam body 1 by welding, binding, etc., so as to improve the overall strength and stability of the dam body 1; the isolation layer 12 prevents moisture from entering the main structure through the drainage layer 13. The isolation layer 12 adopts waterproof materials, such as waterproof cloth, waterproof coating, etc., to ensure that moisture cannot pass through the isolation layer 12 into the main structure; the drainage layer 13 is used to collect and discharge a small amount of infiltrated moisture. The drainage layer 13 adopts materials with good water permeability, such as crushed stone, gravel, etc., to ensure that moisture can be discharged smoothly and avoid water accumulation from causing damage to the water conservancy project; the anti-seepage layer 14 is composed of waterproof materials and is laid on the outside of the main structure of the water conservancy project to resist external water pressure and prevent moisture penetration. The anti-seepage layer 14 adopts high-performance waterproof materials with good impermeability, durability and stability.
[0033] A frame 21 is set on one side of the dam body 1, and a movable sponge board 22 is set inside the frame 21. Once water seepage occurs in the frame 21, the water will be absorbed by the sponge board 22 and stored inside the sponge board 22 to prevent further water penetration. The sponge board 22 can be replaced, which can effectively extend the service life of the water absorption structure 2, thereby improving the capacity of the dam's anti-seepage structure. The frame cover 23 can be opened and locked by the cooperation of the threaded rod 28 and the threaded hole 25, so that the new sponge board 22 can be replaced conveniently.
[0034] Embodiment 2:
[0035] See also Figure 1 - Figure 2 and Figure 4 As shown, two buffer boxes 31 are fixedly installed on the side of the frame 21 away from the anti-seepage layer 14. The two buffer boxes 31 are symmetrically arranged. Buffer plates 32 are movably installed inside the two buffer boxes 31. The buffer plates 32 are slidably fitted with the inner walls of the buffer boxes 31.
[0036] Specifically, a plurality of spring dampers 33 are connected between the buffer plate 32 and the inner wall of the buffer box 31, a water-receiving plate 34 is fixedly connected between the buffer plates 32, two limit grooves 35 are opened on the outer sides of the two buffer boxes 31, the two limit grooves 35 are symmetrically arranged, and limit blocks 36 are movably installed inside the two limit grooves 35. The limit blocks 36 are slidably fitted with the inner walls of the limit grooves 35, and the limit blocks 36 are fixedly connected to the buffer plate 32 near the inner side of the buffer box 31.
[0037] As can be seen from the above, by arranging a movable water-facing plate 34 on the outside of the dam body 1, and through the cooperation of the water-facing plate 34, the buffer plate 32 and the spring damper 33, the buffering of the dam body 1 structure is achieved. The water flow will first contact the water-facing plate 34, and the water-facing plate 34 will transfer the impact force to the spring damper 33 through the buffer plate 32, and then the spring damper 33 will absorb energy to form a buffering effect. In this way, the impact force of the water flow will not affect the dam body 1 structure, thereby improving the service life of the dam body 1 structure.
