Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a reservoir reinforcement and maintenance device and construction method. Background Technology

[0002] Reservoirs are an important component of water conservancy systems, playing a vital role in flood control, urban and rural water supply, and aquaculture. Reservoirs are typically surrounded by dams. During dam construction, to prevent water seepage and subsequent dam collapse, anti-seepage walls are often installed within the dam structure. (Anti-seepage reinforcement is a major engineering measure for addressing dilapidated dams; commonly used anti-seepage reinforcement technologies include grouting anti-seepage reinforcement and anti-seepage wall reinforcement.) These anti-seepage walls maintain the head difference between the two sides of the dam, keeping it within a reasonable range, thereby improving the dam's anti-seepage effect and effectively extending its service life and stability.

[0003] However, during the use of a reservoir, extreme weather such as torrential rain or continuous rainfall is inevitable, causing the water level in the reservoir to rise. When the water level rises, the head difference increases, which in turn increases the seepage pressure. (During normal use, the seepage dam has a certain degree of permeability, allowing water to slowly seep in. However, as the head difference increases, the seepage pressure increases, leading to a higher permeability. To ensure the safety of the structure on the other side of the dam, it is necessary to adjust the permeability of the dam. Currently, there is a lack of a suitable protective mechanism that can adjust the permeability according to the water level and maintain it within a suitable range.) Additionally, strong winds can cause large waves to impact the dam surface. Existing dam protection mechanisms cannot effectively dissipate the energy of the waves and thus reinforce the dam. Summary of the Invention

[0004] The present invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The present invention provides a reservoir reinforcement device and construction method to solve the technical problems that existing dam protection mechanisms cannot adjust the permeability of the dam body according to the water level difference and cannot dissipate energy from waves.

[0005] The present invention adopts the following technical solution: a reservoir reinforcement device and construction method, which also includes a detection and buffering mechanism for detecting water height and buffering water waves, and an adaptive adjustment seepage reinforcement mechanism for adjusting permeability according to water height to avoid excessive permeability affecting the dam body. The detection and buffering mechanism includes a connecting component, a floating deformable wave deflector and an end support adjustment component. The connecting component includes a connecting box and a connecting guide rod, and the connecting guide rod passes through the connecting box so that they slide against each other.

[0006] Furthermore, it also includes a detection and buffering mechanism for detecting water level and buffering water waves, and an adaptive adjustment seepage reinforcement mechanism for adjusting permeability according to water level to avoid excessive permeability affecting the dam body. The detection and buffering mechanism includes a connecting component, a floating deformable wave deflector and an end support adjustment component. The connecting component includes a connecting box and a connecting guide rod, with the connecting guide rod passing through the connecting box to slide against each other.

[0007] Furthermore, the end support adjustment assembly includes a folding support plate, which is connected to the guide groove on the deformation section via an end connecting ball, and the connecting ball is located in the guide groove space of more than 50%. The folding support plate is provided with a clearance hole, the position of which corresponds to the position of the support rod. The folding support plate is connected to the connecting plate via a mating rod.

[0008] Furthermore, the deformation section is made of an elastic material.

[0009] Furthermore, the adaptive adjustment permeation reinforcement mechanism includes a reinforcement box located below the connecting box, and the connecting box is connected to the connecting guide rod. The connecting box is hollow, and a permeation plate is provided on the surface of the connecting box. A permeation pipe is provided inside the connecting box, and several permeation holes for water permeation are provided on the permeation pipe. The permeation pipe is filled with several anti-permeation particles to play a blocking role.

[0010] Furthermore, the cross-section of the permeation tube is a serpentine channel, and movable extrusion blocks are provided in the adjacent gaps. The extrusion blocks are connected to the sidewall of the permeation tube by connecting blocks, and the sidewall of the extrusion block is in contact with the surface of the permeation tube. The contact surface between the extrusion block and the permeation tube is inclined. A trapezoidal mating block is connected inside the extrusion block, and abutting blocks that abut against each other and have a displacement function are provided outside the mating blocks. The abutting blocks pass through the reinforcement box and are connected to the connecting box.

[0011] Furthermore, the contact side between the permeation tube and the extrusion block is made of an elastic material.

[0012] Furthermore, the construction method for the reservoir reinforcement and safety improvement device specifically includes the following steps; S1, Infrastructure: 1. Base reinforcement: Different reinforcement methods are selected according to different foundation conditions. For soft foundations, cement mixing piles (pile diameter 0.5~0.8m) or single-point energy ≥1000 kN·m are used, and seepage prevention curtains are set for gravel layers. 2. Dam foundation excavation: Remove loose soil and level it according to the design slope ratio (e.g., 1:0.3); S2. Construction of seepage prevention structure: Use rotary drilling or impact drilling to make trenches (hole diameter 0.8~1.2m), use mud slurry to protect the wall to prevent hole collapse, then pre-embed grouting pipes and monitoring sensors, then use the guide pipe method to pour the concrete (slump 18~22cm), vibrate and compact in layers, and finally use lock pipes or I-beam joints to connect adjacent wall sections, and coat the surface with epoxy resin for seepage prevention. S3. Dam body formation: Fill the surface of the seepage barrier wall with fillers of different porosities, such as laying layers of gravel of different sizes and rolling them in sequence (compaction degree ≥90%), with a slope of 1:1.5, so that it has a permeability effect. Then, stone slabs are laid on the surface of the filler to complete the dam body formation. S4. Secondary reinforcement construction: After the stone slabs are laid, the prefabricated seepage prevention mechanism is laid on the inside of the stone slabs to give it the function of dam reinforcement. The detection and buffer mechanism in the reinforcement mechanism plays a role in buffering the impact of water waves. The adaptive adjustment seepage reinforcement mechanism adjusts the seepage sealing according to the water height to reduce the water permeability and improve the dam life.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, the detection and buffering mechanism effectively buffers water waves during use. Under different weather conditions and on different water surfaces, the size of the waves varies (the stronger the wind and the larger the water surface, the larger the waves), resulting in varying impact forces. To reduce the impact of the waves, energy dissipation is necessary. The floating deformable breakwater actively deforms when waves impact its surface, resulting in a smaller, more pronounced bend. This smaller bend allows for more contact time and a larger contact area with the breakwater. The steeper bend further forces the waves to break up earlier, dissipating energy through turbulence and friction. Furthermore, the detection and buffering mechanism uses buoyancy materials, ensuring it remains consistently above the water surface (the area where waves form is also primarily on the surface, effectively mitigating the impact of wave impact). Secondly, by using the detection buffer mechanism and the adaptive adjustment permeability reinforcement mechanism in combination, the deeper the water body, the greater the head difference, leading to more severe permeability. The permeability of existing dam structures is fixed (i.e., the permeability between materials during the laying process determines the permeability). At this time, the detection buffer mechanism can judge the water height. When the height is higher, the permeability needs to be reduced accordingly to ensure permeability. The continuous rise of the detection buffer mechanism will change the compaction of the permeable particles in the adaptive adjustment permeability mechanism. By changing the compaction of the permeable particles, the permeability effect is adjusted, so that the permeability of the dam body can be maintained at a relatively low level, effectively reinforcing the dam body.

Detailed Implementation

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0019] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The following is combined Figures 1 to 7As shown, this embodiment of the invention provides a reservoir reinforcement device and construction method, and also includes a detection and buffering mechanism 1 for detecting water height and buffering water waves, and an adaptive adjustment seepage reinforcement mechanism 2 for adjusting permeability according to water height to avoid excessive permeability affecting the dam body. The detection and buffering mechanism 1 includes a connecting component, a floating deformable wave deflector 13, and an end support adjustment component. The connecting component includes a connecting box 11 and a connecting guide rod 12. The connecting guide rod 12 passes through the connecting box 11 and slides against it. During the installation process, the detection and buffering mechanism 1 and the adaptive adjustment seepage mechanism are actually used in conjunction. The detection and buffering mechanism 1 is in a mobile state and adapts to the water level. The infiltration mechanism should be adjusted to a fixed state, and the detection buffer mechanism 1 needs to be able to change synchronously with the water height. At this time, the connecting box 11 is made of a material with a density less than that of water, and the internal floating deformable baffle 13 can also be made of a suitable material depending on the situation (if the size is large, it can be selected at this time to ensure the suspension effect). During the initial construction process, the permeability of the seepage barrier wall itself is fixed. However, as the height difference between the two sides increases, the water head difference will change synchronously. When the water head difference changes, the permeability will change synchronously. Therefore, to ensure the permeability, the density of the permeable material needs to be adjusted. By adjusting the density, the permeability can be indirectly adjusted.

[0023] It should also be noted that the trapezoidal shape of the dam body is relatively large at this time, so the size of the reinforcement mechanism is also large, resulting in a larger buoyancy force, which can effectively achieve the pulling effect.

[0024] Specifically, the floating deformable wave deflector 13 is composed of several deformable segments 131 and movable segments 132, and the deformable segments 131 and movable segments 132 slide against each other. The deformable segment 131 has a guide groove 1311 on its inner side. The connecting assembly includes a connecting plate 14. The connecting plate 14 and the connecting box 11 are connected by several return springs 15 to give it elastic displacement capability. The movable segment 132 and the connecting plate 14 are connected by a connecting rod 25. The movable segment 132 and the connecting plate 14 are connected by an end-point support adjustment assembly. The deformable segment 131 and the connecting box 11 are connected by a support rod 1312.

[0025] Specifically, the end-point support adjustment assembly includes a folding support plate 16. The folding support plate 16 is connected to the guide groove 1311 on the deformable section 131 via an end connecting ball, with the connecting ball occupying more than 50% of the space within the guide groove 1311. The folding support plate 16 has clearance holes, the position of which corresponds to the position of the support rod 1312. The folding support plate 16 is connected to the connecting plate 14 via a mating rod 161. During use, because the deformable section 131 is supported by the end-point support assembly, the greater the displacement of the movable section 132, the smaller the desired angle of the deformable section 131. Therefore, the folding plate folds to reduce the support angle, allowing the deformable section 131 to deform more effectively. The folding support plate 16 is composed of two rotating support plates connected by a connecting shaft.

[0026] Specifically, the deformable segment 131 is made of an elastic material.

[0027] During operation, the deformation section 131 needs to deform, but it also needs to be able to resist wind and waves. Therefore, it needs to have a certain strength, but it also needs to be able to deform. So, a material with a certain hardness but capable of deformation is used, such as a thermoplastic elastomer or polypropylene and a polyurethane foam structure with a closed-cell structure.

[0028] Specifically, the adaptive adjustment permeation reinforcement mechanism 2 includes a reinforcement box 21 located below the connecting box 11 and connected to the connecting guide rod 12. The connecting box 11 is hollow, and a permeation plate 23 is provided on its surface. A permeation tube 22 is provided inside the connecting box 11, and several permeation holes 24 are provided on the permeation tube 22 for water permeation. The permeation tube 22 is filled with several anti-permeation particles to act as a barrier. The permeation particles can be polyurethane foam particles with a certain elasticity.

[0029] Specifically, the permeation tube 22 has a serpentine cross-section, with movable compression blocks 28 positioned at adjacent gaps. The compression blocks 28 are connected to the sidewall of the permeation tube 22 via connecting blocks 29, and the sidewall of the compression blocks 28 contacts the surface of the permeation tube 22. The contact surface between the compression blocks 28 and the permeation tube 22 is inclined. A trapezoidal mating block 26 is connected inside the compression blocks 28, and an abutting block 27 is provided outside the mating block 26, which abuts against each other, allowing for displacement. The abutting block 27 penetrates the reinforcing box 21 and is connected to the connecting box 11 via a connecting rod 25. Due to its trapezoidal shape, the vertical displacement of the abutting block 27 allows for different effects on the compression block 28, thereby increasing or decreasing the tightness and providing multiple adjustment options.

[0030] Specifically, the contact side between the permeation tube 22 and the extrusion block 28 is made of an elastic material.

[0031] Specifically, since the compactness needs to be changed while the number of particles remains the same, it is necessary to change the size of the space where the particles are located, that is, to change the internal size of the permeation tube 22. This is done by squeezing or stretching the permeation tube 22, thereby changing the inner diameter.

[0032] Working principle: When using this device for reinforcement, different functions will be explained separately. When the device is used to prevent wave impact, the connecting box 11 will always be suspended above the water due to the buoyancy of the water. When water waves impact the floating deformable wave deflector 13, the deformable section 131 is fixed by the support rod 1312 that passes through the folding support plate 16, while the movable section 132 is connected to the movable connecting plate 14. This causes the movable section 132 to fluctuate due to the influence of water waves. In windy weather, there are often large waves in stages, and the stronger the wind, the larger the waves and the stronger the impact force. When the waves impact the movable section 132, it will move inward (when the movable section 132 moves inward, the arc segment formed by the movable section 132 and the deformable section 131 becomes deeper). When section 32 moves, it will compress the deformation section 131, causing both ends of the deformation section 131 to have a deformation tendency. At the same time, when the moving section 132 moves, it will drive the connecting plate 14 to move through the connecting rod 25 (described as moving backward at this time). One of the folding support plates 16 is connected to the connecting plate 14 through the support rod 1312, so that when the connecting plate 14 moves backward, it will pull the folding support plate 16. When the folding support plate 16 is stretched, the unfolding angle of the folding support plate 16 becomes smaller, thereby reducing the support arc of the folding support plate 16 on the deformation section 131 (that is, the angle of the deformation section 131 can become smaller, so that the opening angle of the entire compression at both ends becomes uniformly smaller). This achieves the effect of adjusting the size and depth of the arc according to the size of the waves. By using a smaller and deeper arc, the impact intensity of the water waves is weakened, thereby achieving the effect of reinforcing the dam body. Secondly, as the water storage increases, the water level rises, leading to a greater pressure difference between the two sides of the dam. This increased pressure difference alters water permeability. To improve permeability, the compactness of the particles needs to be changed. However, the permeability of the dam body and its filling material cannot be altered. Therefore, the compactness of the particles within the reinforcement mechanism needs to be changed. During normal use, water flows out through the permeation holes 24 in the permeation pipe 22 inside the reinforcement box 21. The permeation pipe 22 is filled with permeable particles. As the water depth increases, the connecting box 11 rises. This rise causes the connecting box 11 to move upwards via the connecting block 29, which in turn moves the abutment block 27 upwards. When the abutment block 27 moves upwards, it squeezes the mating block 26, causing the mating block 26 to move inwards. The movement of the permeable pipe will simultaneously drive the squeezing block 28 to move inward. The inward movement of the squeezing block 28 will squeeze the side wall of the permeable pipe 22, thereby squeezing the permeable pipe 22. After squeezing the permeable pipe 22, it will also have a compaction effect on the internal particles, making the internal particles more compact. With higher compaction, the permeability will be reduced in a way, thus achieving the function of adaptively adjusting the permeability with changes in water height, avoiding damage to the dam body due to high permeability. Secondly, with continuous use, when the permeable pipe is pulled, the gaps inside the permeable pipe will increase, the compactness between particles will decrease, and even gaps will appear between particles. At this time, when there are impurities between the particles, the presence of gaps can be cleaned by the action of the water.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
