Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically to a seepage prevention and protection structure for water conservancy engineering dams. Background Technology

[0002] my country has relatively abundant water resources, resulting in a variety of water conservancy projects. These projects enable the effective control and allocation of surface water and groundwater. Dams are the main hydraulic structures for reservoir operation and flood control. Dams are mainly made of concrete. Existing dam structures are generally simple in function and are prone to erosion under prolonged water scouring, leading to soil loss, disruption of ecological balance, and low stability. Moreover, dams lack waterproofing, making them susceptible to water seepage and collapse, which can cause severe flooding. Therefore, people generally use stones and sandbags to thicken and reinforce dams.

[0003] Prior art 1 (application number: CN202422241183.8) discloses a seepage prevention and protection structure for a water conservancy project dam, belonging to the technical field of seepage prevention and protection devices. It includes a slope protection body composed of a horizontal slope and a sloping slope. A seepage prevention and soil stabilization structure is provided on one side of the sloping slope, and a water storage and irrigation structure is provided at the top of the horizontal slope. The seepage prevention and soil stabilization structure includes several water troughs. This seepage prevention and protection structure for a water conservancy project dam, by setting up the seepage prevention and soil stabilization structure, allows for the planting of plants on the sloping slope of the dam through the placement of troughs and flower pots. The plant roots and stems then hold the soil in place, thus stabilizing it. Furthermore, the plants require water, and the structure absorbs some of the water that penetrates deep into the soil, thereby improving overall stability. The water troughs also assist in irrigating the plant roots and stems, and a first filter plate prevents impurities from clogging the water troughs.

[0004] However, during the implementation of the relevant technologies, the following problems were found in the seepage prevention and protection structure of the above-mentioned water conservancy project dam: the existing dam structure is relatively complex and difficult to construct. The entire dam has a water storage and irrigation structure and a dry water channel, which makes the entire dam hollow and easily corroded by water, thus making it prone to collapse. Utility Model Content

[0005] This utility model proposes a seepage prevention and protection structure for water conservancy engineering dams, which solves the problems of existing dam structures being relatively complex, difficult to construct, and having water storage and irrigation structures and dry water channels, resulting in hollow interiors that are easily corroded by water and prone to collapse.

[0006] The technical solution of the utility model is as follows: A seepage prevention and protection structure for a dam in a water conservancy project, including a dam casting protection layer, which is cast on the outer surface of the dam, and an anti-seepage soil layer is covered on the inclined part in the middle of the dam casting protection layer;

[0007] It further includes:

[0008] Soil-fixing blocks, which are fitted on the outer surface of the anti-seepage soil layer, and two soil-fixing blocks are snap-fitted and spliced together through convex blocks and grooves on the left and right;

[0009] Installation holes, which are opened on the outer surface of the soil-fixing blocks, and a plug cone is connected through the inside of the installation holes.

[0010] Preferably, cylindrical columns and circular grooves are respectively installed at the front and rear ends of the soil-fixing blocks, and the front and rear single bodies of the two soil-fixing blocks are snap-fitted and spliced together through the cylindrical columns and circular grooves.

[0011] Preferably, the soil-fixing block has a "mouth" - shaped structure, and a protective net is fixedly connected to the upper end of the inner wall in the middle of the soil-fixing block, and the depth dimension of the middle opening of the soil-fixing block is greater than the thickness dimension of the protective net.

[0012] Preferably, a plug rod is integrally and fixedly connected to the upper end of the plug cone, and a limiting block is fixedly connected to the upper end of the plug rod, and a "T" - shaped structure is formed between the limiting block and the plug cone.

[0013] Preferably, rubber strips are evenly spaced and adhesively connected to the front and rear outer surfaces of the plug rod, and the plug rod is closely fitted with the inner wall of the installation hole through the rubber strips.

[0014] Preferably, the opening dimension of the installation hole is smaller than the size of the limiting block, and the limiting blocks are arranged at equal intervals on the upper end surface of the soil-fixing block, and there is no intersection between the limiting block and the inner wall of the soil-fixing block.

[0015] The working principle and beneficial effects of the utility model are as follows: The dam structure is simple, convenient for installation and assembly. At the same time, it also has an anti-seepage structure, which protects the dam from being corroded and ulcerated by water, and improves the service life of the dam.

[0016] In the utility model, soil-fixing blocks and an anti-seepage soil layer are provided. The soil-fixing blocks are connected to each other through the snap-fitting of convex blocks and grooves. At the same time, the splicing between the cylindrical columns and circular grooves facilitates the fixation of the splicing between the soil-fixing blocks, facilitates the separation of the anti-seepage soil layer by the soil-fixing blocks, facilitates the planting of turf, and improves the water-locking and anti-seepage effect;

[0017] In this utility model, a protective net and a soil stabilizing block are provided. The protective net is fixedly installed on the upper part of the inner wall of the soil stabilizing block, which facilitates the growth of turf and also helps to prevent soil erosion. It also protects the impermeable soil stabilizing layer that is in contact with the lower end of the soil stabilizing block, so as to facilitate the stable growth of turf and prevent water from seeping downward, thus playing a water-locking role.

[0018] In this utility model, a limiting block and a cone are provided. The limiting block is fixed to the seepage-proof soil layer by hammering downward with the cone. The size of the limiting block is larger than the opening size of the installation hole, which makes it convenient to limit the position of the soil block and to firmly fix the soil block to avoid loosening.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution for a seepage prevention and protection structure for a water conservancy project dam: including a dam pouring protective layer 1, a seepage prevention and soil stabilization layer 2, soil stabilization blocks 3, a protective net 4, a protrusion 5, a groove 6, a limiting block 7, a cylinder 8, an insert cone 9, an insert rod 10, a rubber strip 11, a mounting hole 12, and a circular groove 13.

[0027] The working principle and usage process of the present utility model are as follows: First, in combination with Figure 1 , Figure 2 and Figure 3 as shown, cylinders 8 and circular grooves 13 are respectively installed at the front and rear ends of the soil-fixing block 3, and the front and rear monomers of the two soil-fixing blocks 3 are snap-fitted and spliced through the cylinders 8 and circular grooves 13. The soil-fixing block 3 has a "mouth" - shaped structure, and the protective net 4 is fixedly connected to the upper end of the inner wall in the middle of the soil-fixing block 3. Moreover, the depth dimension of the middle opening of the soil-fixing block 3 is greater than the thickness dimension of the protective net 4. The soil-fixing blocks 3 are connected to each other by splicing. When the soil-fixing block 3 is installed on the outer surface of the anti-seepage soil layer 2, the monomers of the soil-fixing block 3 form a grid-like structure. Green plants are planted at the connection between the middle opening of the soil-fixing block 3 and the anti-seepage soil layer 2, dividing the large area of green plants into small pieces, so as to facilitate firmly grasping the soil, locking water, preventing water from seeping downward, and avoiding water body loss, which is convenient for protecting the dam and preventing corrosion and ulceration;

[0028] In combination with Figure 2 and Figure 4 as shown, the upper end of the insertion cone 9 is integrally and fixedly connected to the insertion rod 10, and the upper end of the insertion rod 10 is fixedly connected to the limit block 7. Moreover, a "T" - shaped structure is formed between the limit block 7 and the insertion cone 9. Rubber strips 11 are evenly spaced and adhesively connected to the front and rear outer surfaces of the insertion rod 10, and the insertion rod 10 is in close contact with the inner wall of the installation hole 12 through the rubber strips 11. The opening dimension of the installation hole 12 is smaller than the size of the limit block 7, and the limit blocks 7 are evenly spaced on the upper end surface of the soil-fixing block 3, and there is no intersection between the limit block 7 and the inner wall of the soil-fixing block 3. The insertion cone 9 is connected through the soil-fixing block 3, which is convenient for installation and disassembly. After the soil-fixing block 3 is spliced, the insertion cone 9 penetrates inside the soil-fixing block 3. Hammering the insertion cone 9 downward is convenient for inserting the insertion cone 9 into the anti-seepage soil layer 2 to strengthen the installation and fixation of the soil-fixing block 3. At the same time, the insertion cone 9 is connected to the limit block 7 through the insertion rod 10, and the outer surface of the insertion rod 10 is adhesively connected to the rubber strip 11, so as to firmly fix the insertion cone 9 at the soil-fixing block 3 to avoid loosening. At the same time, the size of the limit block 7 is larger than the opening dimension of the installation hole 12, so as to facilitate firmly fixing the soil-fixing block 3 and the anti-seepage soil layer 2, which is convenient for installation and fixation. This is the working process of the anti-seepage protection structure of the dam in the water conservancy project.

[0029] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
