Description

Technical Field

[0001] The utility model relates to the technical field of dam anti-seepage, in particular to an anti-seepage device for a reservoir dam. Background Art

[0002] Dams are key facilities in water conservancy projects, used to intercept water sources, regulate water volume, and provide functions such as flood control, irrigation, and power generation. Generally, a dam consists of a main dam, an auxiliary dam, a gravity dam, a normal spillway, an emergency spillway, a backup spillway, and a power station. During the long-term operation of the dam, the impact of water flow on its structure may cause seepage, posing a threat to the safety of the dam. Therefore, anti-seepage protection has become an important part of dam design and maintenance. However, existing anti-seepage technologies have some problems in application. For example, for large or long dams, there is a lack of reliable connection methods between multiple anti-seepage plates, resulting in a complicated and inefficient installation process. In addition, the connection gaps between the anti-seepage plates easily become seepage points, and the existing technology lacks anti-seepage protection measures for these gaps, further increasing the risk of seepage. These problems have put higher demands on dam anti-seepage technology, which urgently needs to be improved and optimized.

[0003] This experimental team has been browsing and studying a large amount of relevant records and materials on dam anti-seepage technologies for a long time. At the same time, relying on relevant resources and conducting a large number of relevant experiments, it was found through extensive searches that the construction complexity and technical limitations of existing technologies have significant defects in practice.

[0004] The present invention is made in order to solve the problems commonly existing in this field such as construction complexity, durability of anti-seepage effect and adaptability. Utility Model Content

[0005] The purpose of the utility model is to propose an anti-seepage device for reservoir dams in response to the deficiencies in the current field.

[0006] In order to overcome the deficiencies of the prior art, the present invention adopts the following technical solutions:

[0007] An anti-seepage device for a reservoir dam, comprising a fixed crossbar fixed to the side of the upstream side of the dam body, an inclined rod fixed to the fixed crossbar at the bottom and extending to the top of the dam body at the top, a plurality of anti-seepage plates respectively fitted on the inclined rods, and a fixing assembly for fixing the anti-seepage plates on the inclined plates.

[0008] The fixed cross bar is made of hot-dip galvanized steel or stainless steel, and is fixedly connected to the dam body by chemical anchors or expansion bolts. The inclined rods are arranged parallel to the sides of the dam body. At least two inclined rods are connected and fixed to each fixed cross bar. An anti-seepage plate is respectively mounted on two adjacent inclined rods. Several anti-seepage plates that are tightly abutted against each other are mounted on two adjacent inclined rods. The inclined rods are made of glass fiber reinforced plastic or corrosion-resistant alloy steel. The bottom of the inclined rod is connected to the fixed cross bar by bolts and welding.

[0009] Furthermore, the anti-seepage plate includes a first plate body in contact with the dam body and having flexible deformation and a second plate body correspondingly away from the dam body and being solid and hard. The first plate body and the second plate body are fixed into one by hot pressing or adhesive.

[0010] Furthermore, the plate surface where the second plate body is connected to the first plate body is used as the connecting surface, and the side of the second plate body correspondingly away from the first plate body is used as the water flow impact surface. The second plate body is provided with a through-channel that passes through from top to bottom, and buffer holes that are evenly distributed on the water flow impact surface of the second plate body and are connected to the through-channel. The buffer holes are used to guide water flow into the through-channel and discharge it, thereby reducing the resistance of water flow to the anti-seepage plate when the anti-seepage plate is installed, especially when the anti-seepage plate is moved along the tilting rod and adjusted to different positions of the dam body, effectively reducing the interference and resistance of the water flow.

[0011] The first plate body includes two matching channels, which are set through the upper and lower plate walls of the first plate body. At the same time, the matching channels can be fitted on the tilt rod, and the shape of the matching channels matches the shape of the tilt rod.

[0012] Furthermore, the fixing assembly includes a sleeve that can be sleeved on the top of the tilting rod, pin holes aligned on the sleeve and the tilting rod respectively, a pin shaft that fixes the sleeve and the tilting rod by penetrating the pin holes, and an abutting rod one end of which is fixed on the sleeve and the other end of which is abutted against the anti-seepage plate on the tilting rod.

[0013] The beneficial effects achieved by the utility model are:

[0014] 1. Highly efficient anti-seepage performance: Through the combination of the flexible first plate and the rigid second plate, the flexible layer is tightly attached to the dam body to provide a good sealing effect, and the second plate disperses and withstands the impact of water flow, which significantly improves the overall anti-seepage performance of the device and effectively protects the dam structure.

[0015] 2. Durability and adaptability: The flexible first plate is made of polymer composite rubber and reinforced fiber mesh layer, and the rigid second plate is protected by high-strength concrete and epoxy resin coating. It has excellent corrosion resistance, erosion resistance and structural strength, adapts to complex water flow environment and extends service life.

[0016] 3. Easy maintenance: The sealing plate is securely installed via tilting rods and fixing components and can be disassembled and replaced, facilitating regular maintenance or replacement of the anti-seepage blocks and significantly improving the maintenance efficiency of the dam's anti-seepage device.

[0023] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with its embodiments; it should be pointed out that the specific embodiments described herein are only used to explain the present invention and are not used to limit this case. For those skilled in the art, after reviewing the detailed description below, other systems, methods and / or features of this embodiment will become apparent. In addition, the terms describing the positional relationship in the accompanying drawings are only for illustrative purposes and cannot be understood as limiting this patent. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0024] Example 1: Combined with the attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 This embodiment constructs an anti-seepage device for a reservoir dam, comprising a fixed crossbar fixed to the side of the upstream side of the dam body, an inclined rod fixed to the fixed crossbar at the bottom and extending to the top of the dam body at the top, a plurality of anti-seepage plates respectively fitted on the inclined rods, and a fixing assembly for fixing the anti-seepage plates on the inclined plates.

[0025] The fixed crossbar is made of hot-dip galvanized steel or stainless steel. The fixed crossbar is fixed to the dam body through chemical anchor bolts or expansion bolts. The fixing parts of the chemical anchor bolts or expansion bolts and the dam body are waterproof and sealed to ensure that the fixed crossbar can withstand water impact and long-term load.

[0026] The tilting rods are arranged parallel to the sides of the dam body, and at least two tilting rods are connected and fixed to each fixed crossbar. An anti-seepage plate is respectively sleeved and matched on two adjacent tilting rods. A plurality of anti-seepage plates are sleeved on two adjacent tilting rods that are tightly abutted against each other. The tilting rods are made of glass fiber reinforced plastic or corrosion-resistant alloy steel. The tilting rods are durable and lightweight. The bottom of the tilting rods is connected to the fixed crossbar by bolts and welding.

[0027] The anti-seepage plate includes a first plate body that contacts the dam body and has flexible deformation, and a second plate body that is relatively far away from the dam body and is solid and hard. The first plate body and the second plate body are fixed into one by heat pressing or adhesive.

[0028] The first plate body is formed by stacking and hot-pressing several layers of polymer composite rubber layers and several layers of reinforced fiber mesh layers. The polymer composite rubber layer is composed of EPDM rubber and chlorinated polyethylene. The polymer composite rubber layer has flexibility and corrosion resistance. The reinforced fiber mesh layer is woven from high-strength polyester fiber or glass fiber. The reinforced fiber mesh layer provides tensile strength and tear resistance for the first plate body. The first plate body is tightly attached to the side of the dam body to ensure the sealing of the side. The first plate body significantly improves the durability and adaptability of the first plate body through the combination of flexible deformation and overall strength.

[0029] The second plate is cast by high-strength concrete, and the surface of the second plate is coated with epoxy resin coating to improve the anti-scouring performance of the second plate and prevent the concrete of the second plate from being worn or deteriorated due to long-term exposure to water flow.

[0030] The plate surface where the second plate body is connected to the first plate body is used as the connecting surface, and the side of the second plate body that is away from the first plate body is used as the water flow impact surface. The second plate body is provided with a through-channel that runs through from top to bottom, and buffer holes that are evenly distributed on the water flow impact surface of the second plate body and are connected to the through-channel. The buffer holes are used to guide water flow into the through-channel and discharge it, thereby reducing the resistance of water flow to the anti-seepage plate when the anti-seepage plate is installed, especially when the anti-seepage plate is moved along the tilting rod and adjusted to different positions of the dam body, effectively reducing the interference and resistance of the water flow.

[0031] The first plate body includes two matching channels, which are set through the upper and lower plate walls of the first plate body. At the same time, the matching channels can be matched with the tilt rod. The shape of the matching channels matches the shape of the tilt rod.

[0032] The fixing assembly includes a sleeve that can be sleeved on the top of the tilting rod, pin holes aligned with the sleeve and the tilting rod, a pin shaft that penetrates the pin holes to fix the sleeve and the tilting rod, and an abutting rod with one end fixed to the sleeve and the other end abutting against the anti-seepage plate on the tilting rod.

[0033] The sleeve and the tilting rod are respectively provided with corresponding pin holes. When the sleeve is sleeved on the top of the tilting rod, the pin holes on the sleeve and the tilting rod are completely aligned to form a through connection channel. By inserting the pin shaft into the connection channel, the sleeve and the tilting rod are firmly connected. At the same time, the abutment rod provides support force, so that the anti-seepage plate can be closely attached to the tilting rod and the side of the dam body, thereby enhancing the stability and durability of the device.

[0034] The anti-seepage device of the present invention realizes efficient anti-seepage protection of the dam through the organic combination of flexible and rigid materials. The flexible first plate body is closely attached to the side of the dam body, can adapt to the irregular shape of the dam body surface and provide sealing performance. The rigid second plate body is cast by high-strength concrete. At the same time, the second plate body is provided with buffer holes and through channels to guide the water flow to disperse and reduce the impact force, thereby further protecting the first plate body and the dam body.

[0035] The anti-seepage plate is supported by tilting rods and firmly connected to the fixed components. The combination of the sleeve, pin hole, pin shaft and abutment rod ensures the stability of the installation and realizes the flexibility of the anti-seepage device. The sealing plate can be disassembled and replaced regularly, which significantly improves the maintenance efficiency, extends the overall service life of the anti-seepage device, and the anti-seepage efficiency of the dam.

That is, the methods, systems and devices discussed above are examples. Various configurations can appropriately omit, replace or add various processes or components.
