Abstract
Description
Technical Field
[0001] This utility model relates to the field of water conservancy engineering and ecological restoration technology, and in particular to a dam reinforcement structure for ecological dams. Background Technology
[0002] With increasing emphasis on ecological environmental protection, ecological dams, as a technical means that combines water conservancy engineering with ecological restoration, have been widely used. Ecological dams not only have traditional functions such as flood control and water storage, but also improve the aquatic ecological environment through vegetation cover and biological habitats. However, during long-term use, ecological dams often face problems such as insufficient dam stability and susceptibility to water erosion, leading to structural damage and even collapse. Currently, the industry mainly uses traditional methods such as concrete reinforcement and steel cage filling for dam reinforcement, but these methods often damage the ecological environment and fail to achieve the dual goals of engineering and ecology. Therefore, how to ensure dam stability while maximizing the protection of the ecological environment has become the core challenge in the current development of ecological dam technology.
[0003] A search revealed Chinese Patent Publication No. CN219930882U, which discloses an ecological water-retaining dam. This dam includes an inverted filter layer with ecological gabions on both sides. Aquatic plants are planted on both sides of the gabions, and the top of the gabions is above the normal water level. The top of the gabions is equipped with a steel mesh, and the gabions have internal reinforcing ribs. A reinforced concrete base slab is located at the bottom of the gabions, followed by a plain concrete cushion layer, and then a riprap replacement layer. This ecological water-retaining dam ecologically isolates the internal enclosed water body from the external river channel, maintaining a relatively stable water level. During the rainy season, the dam's interior is equipped with functional filter media such as volcanic rock, biomass filler, and maifanite, reducing the impact of heavy rainfall on the external river's water environment.
[0004] The device uses a reinforced concrete base slab as the foundation of the dam body. However, the base of the dam body is usually underwater, which increases the actual construction difficulty. Furthermore, when the reinforced concrete base slab is at the bottom of the river for a long time, it will be corroded by the river water, which will affect the strength of the reinforced concrete base slab and consequently the overall strength of the dam body. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a dam reinforcement structure for ecological dams, aiming to improve the problems of excessive construction difficulty and inconvenient maintenance of existing ecological dams.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dam body reinforcement structure for ecological dams, comprising a rock stratum zone, wherein a dam body main body is fixedly installed on the top surface of the rock stratum zone, a reinforcement grid is installed on the inner side of the dam body main body, and multiple anchoring components are connected to the inner side of the reinforcement grid.
[0007] The above technical solution involves using sand and gravel to construct the main body of the dam, which is relatively simple to construct and has strong stability. The reinforcing mesh is made of high-strength environmentally friendly materials and is installed on the inside of the main body of the dam, which further enhances the stability of the main body of the dam.
[0008] As a further description of the above technical solution: the plurality of anchoring components include anchor rods, which are installed on the inner side of the dam body, with the bottom end of the anchor rod extending into the interior of the rock stratum, and the other end of the anchor rod being fixedly connected to the reinforcement grid.
[0009] The above technical solution involves using galvanized steel anchors with a diameter of 20mm and a length determined by geological conditions. One end of the anchor is inserted into the rock strata, while the other end is connected to the reinforcement grid, thereby further enhancing the stability of the dam body.
[0010] As a further description of the above technical solution:
[0011] The bottom end of the anchor rod is fixedly connected to a pointed cone, which is inserted into the interior of the rock stratum.
[0012] The above technical solution utilizes a pointed tip, allowing the cone to be inserted into the rock strata, thus facilitating the installation of the anchor rod within the rock layer. This increases the ease of anchor rod installation.
[0013] As a further description of the above technical solution:
[0014] A flexible buffer layer is provided between the main body of the dam and the reinforcing grid, and the flexible buffer layer is fixedly installed on the inner wall of the main body of the dam.
[0015] Through the above technical solution: the flexible buffer layer is made of silicone rubber, which has high and low temperature resistance and weather resistance. When the main body of the dam is impacted by water flow, the deformation of the flexible buffer layer can absorb part of the impact force, thereby buffering the impact force on the main body of the dam and further enhancing the impact resistance of the main body of the dam.
[0016] As a further description of the above technical solution:
[0017] The surface of the reinforced mesh has multiple drainage holes, and multiple spikes are fixedly connected to the surface of the reinforced mesh.
[0018] The above technical solution allows water to flow through the drainage holes, forming multiple smaller water flow channels as it passes through the reinforced grid. This disperses the originally concentrated water flow impact force to multiple points, thereby reducing the overall impact on the reinforced grid.
[0019] As a further description of the above technical solution:
[0020] The spikes are evenly distributed on the outer surface of the reinforced grid, and the spikes are inserted into the interior of the flexible buffer layer.
[0021] The above technical solution allows for the initial installation of the reinforcing mesh by inserting spikes into the interior of the flexible buffer layer, thereby increasing the ease of installation.
[0022] As a further description of the above technical solution:
[0023] The outer side of the main body of the dam is provided with a planting layer, and the two sides of the planting layer are provided with extension layers.
[0024] The above technical solution allows for the planting of aquatic plants on the surface of the planting layer. By planting taller aquatic plants on the surface of the extension layer, the roots of these plants intertwine with the planting and extension layers, thus buffering the water flow and further enhancing the dam's resistance to impact.
[0025] As a further description of the above technical solution:
[0026] Geotextile is provided between the planting layer and the main body of the dam.
[0027] The above technical solution, through the maintenance of geotextile, can prevent the soil in the planting layer and extension layer from flowing away, thus ensuring the growth environment of aquatic plants on the planting layer and extension layer.
[0028] This utility model has the following beneficial effects:
[0029] 1. This utility model enhances the protective performance of the reinforcement grid by setting a reinforcement grid on the inner side of the dam body and using anchor rods in the anchoring assembly. The anchor rods extend into the interior of the rock stratum and are fixedly connected to the reinforcement grid at the other end. This enhances the overall protective performance of the dam body. The overall construction is relatively simple, the cost is reduced, and the practicality of the ecological dam reinforcement technology is improved.
[0030] 2. This utility model incorporates a flexible buffer layer between the main body of the dam and the reinforcing grid. When the main body of the dam is impacted by water flow, the flexible buffer layer can absorb part of the impact force, thereby buffering the impact force to a certain extent. This improves the overall impact resistance of the dam and enhances its overall stability. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0038] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a dam body reinforcement structure for an ecological dam, including a rock layer zone 1, a dam body main body 4 fixedly installed on the top surface of the rock layer zone 1, a reinforcement grid 6 installed on the inner side of the dam body main body 4, and multiple anchoring components 7 connected to the inner side of the reinforcement grid 6.
[0039] Specifically, because rivers erode and transport the earth's surface during their formation and evolution, they may cut through the surface soil, exposing the underlying rock layers. Therefore, the dam body 4 of this device is suitable for various scenarios. The dam body 4 is constructed from sand and gravel materials, making its construction simpler and cost-effective compared to reinforced concrete pouring, while also enhancing its practicality. The reinforcing mesh 6 is made of high-strength environmentally friendly materials and is embedded inside the dam body 4, thereby improving the overall stability of the dam body 4 and enhancing its impact resistance.
[0040] Reference Figure 2 and Figure 4Multiple anchoring components 7 include anchor rods 7001, which are installed on the inner side of the dam body 4, with the bottom end of the anchor rods 7001 extending into the interior of the rock stratum 1, and the other end of the anchor rods 7001 being fixedly connected to the reinforcing grid 6.
[0041] Specifically, the reinforcing mesh 6 is made of high-strength polyethylene material, which has good tensile strength and corrosion resistance. The anchor rods 7001 are made of galvanized steel with a diameter of 20mm. The length is determined according to geological conditions. Different lengths of anchor rods 7001 can be selected according to the height of the dam. After the reinforcing mesh 6 is installed on the inner side of the dam body 4, it is connected to the underground rock strata through the anchor rods 7001 to form a stable support structure. This further enhances the stability of the dam body 4 and improves its impact resistance. Moreover, the stability of the dam body 4 can be improved by using multiple sets of anchor rods 7001, which greatly increases the convenience of construction and enhances economic benefits.
[0042] Reference Figure 4 An anchor rod 7001 has a pointed cone 8 fixedly connected to its bottom end, and the pointed cone 8 is inserted into the interior of the rock stratum 1.
[0043] Specifically, the pointed cone 8 at the bottom of the anchor rod 7001 makes it easier to insert the anchor rod 7001 into the interior of the rock stratum 1, thereby enhancing the convenience of installing the anchor rod 7001. The top of the anchor rod 7001 is fixedly connected to the top of the dam body 4, thereby also providing support for the dam body 4.
[0044] Reference Figure 2 A flexible buffer layer 5 is provided between the dam body 4 and the reinforcing grid 6, and the flexible buffer layer 5 is fixedly installed on the inner wall of the dam body 4.
[0045] Specifically, the flexible buffer layer 5 used in this device is made of silicone rubber, which is a material layer with softness, elasticity and good energy absorption characteristics. When subjected to external impact, it absorbs and dissipates energy through its own deformation, thereby reducing the peak value and duration of the impact force and protecting the protected object or structure from damage. It can also play a role in dispersing pressure, making the pressure evenly distributed and avoiding damage caused by excessive local pressure. Furthermore, when the main body of the dam 4 is impacted by water flow, the flexible buffer layer 5 can absorb part of the impact force on the main body of the dam 4 through deformation, thereby improving the overall impact resistance of the main body of the dam 4.
[0046] Reference Figure 3 The surface of the reinforcing mesh 6 has multiple drainage holes 9, and multiple spikes 10 are fixedly connected to the surface of the reinforcing mesh 6.
[0047] Specifically, when water seeps into the interior of the dam body 4, the water flow on both sides of the dam body 4 can be interconnected through the drainage holes 9. This allows the water flow to form multiple smaller water flow channels on the surface of the reinforced grid 6, dispersing the originally concentrated water flow impact force to multiple points, thereby reducing the impact force on the overall slab surface and further improving the overall impact resistance of the dam body.
[0048] Reference Figure 3 The spikes 10 are evenly distributed on the outer surface of the reinforced mesh 6, and the spikes 10 are inserted into the interior of the flexible buffer layer 5.
[0049] Specifically, by inserting the spikes 10 into the interior of the flexible buffer layer 5, the reinforcing mesh 6 can be fixedly installed onto the surface of the flexible buffer layer 5. The anchor rods 7001 can support and fix the reinforcing mesh 6, thereby ensuring the stability of the installation of the reinforcing mesh 6. Furthermore, by inserting the spikes 10 into the interior of the flexible buffer layer 5, the reinforcing mesh 6 can be initially installed, thereby increasing the convenience of installing the reinforcing mesh 6.
[0050] Reference Figure 1 and Figure 2 A planting layer 2 is provided on the outer side of the main body 4 of the dam, and an extension layer 11 is provided on both sides of the planting layer 2;
[0051] Specifically, through planting layer 2, aquatic plants can be planted on top of planting layer 2. The aquatic plants can cover the surface of the dam body, and their root systems are connected to the main body of the dam body 4. When encountering water flow impact, the aquatic plants on the outside can buffer the impact force of the water flow, thereby further improving the impact resistance of the main body of the dam body 4. By planting tall aquatic plants, such as reeds, on the surface of extension layer 11, reeds have very developed root systems that can penetrate deep into the soil to form a huge root network. These roots can firmly hold the soil, enhance the stability of extension layer 11, and make it difficult for reeds to be uprooted when impacted by water flow. Moreover, the stems of reeds have good flexibility and elasticity. Under the impact of water flow, they can bend with the direction of water flow, which can effectively buffer the impact force of water flow and reduce the possibility of stem breakage due to direct confrontation, thereby further improving the overall stability of the dam body.
[0052] Reference Figure 2 Geotextile 3 is provided between the planting layer 2 and the main body of the dam 4;
[0053] Specifically, by setting up geotextile 3, soil erosion can be prevented, the reinforcement effect of the vegetation layer can be enhanced, and the overall impact resistance of the dam can be further improved.
[0054] Working principle: Clean the entire surface of the dam body to ensure that the construction area is flat, connect the reinforcing mesh 6 to the anchor rod 7001 and fix the reinforcing mesh 6 to the surface of the flexible buffer layer 5, ensure that the anchor rod 7001 penetrates into the rock layer area 1, lay a planting area and extension layer on the dam body surface, plant suitable aquatic plants, and regularly check the reinforcement structure and vegetation growth to ensure the long-term stability of the dam body.
[0055] The reinforcing grid 6 is installed inside the main body 4 of the dam and connected to the underground rock strata through the anchor rod 7001 to form a stable support structure. The planting layer 2 and the extension layer 11 cover the outside of the dam body. The plant roots intertwine with the planting layer 2 and the extension layer 11 to further enhance the stability of the dam body. When the water flow scours the entire dam body, the reinforcing grid 6 and the anchor rod 7001 share the impact force to prevent damage to the dam structure.
[0056] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
