[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present utility model.

[0029] At present, the overall type of wave protection wall structure is usually adopted, and the face plate is usually constructed by means of block pouring in the construction of the face plate dam, which is to adapt to the shrinkage deformation of concrete and the requirements of the construction process. However, the existing wave protection wall often fails to fully consider the influence of the block of the face plate during design and construction. As a result, the wave protection wall cannot adapt to the stress change at the block of the face plate. When the face plate deforms due to temperature change, dam body settlement and other factors, the wave protection wall at the block will be subjected to additional stress concentration. For example, when the temperature decreases, the face plate shrinks, and tensile stress is generated between the blocks. If the wave protection wall cannot effectively adapt to such deformation, cracks will appear at the corresponding parts of the blocks. When the dam body is subjected to uneven settlement, the deformation difference of the face plate will be transmitted to the wave protection wall. Since the joints of the wave protection wall do not correspond to the blocks of the face plate, the stress cannot be reasonably dispersed, and thus the wave protection wall structure is damaged. Not only the waterproof performance of the wave protection wall is reduced, resulting in leakage, but also the integrity and stability of the structure are further weakened, which threatens the safe operation of the dam.

[0030] Therefore, in order to avoid stress concentration at the block of the face plate and damage to the wave protection wall structure, the present embodiment proposes a new wave protection wall structure of a concrete face plate dam.

[0031] With reference to Figures 1 to 5 A wave protection wall structure of a concrete face plate dam, the wave protection wall structure comprising:

[0032] A base 1 connected with the top surface of the concrete face plate dam, the base 1 having a first deformation joint, the first deformation joint dividing the base 1 and matching the block of the face plate on the top surface of the concrete face plate dam, a first flexible sealing layer being arranged in the first deformation joint, and the base 1 being provided with a mounting groove 2 along the dam axis direction;

[0033] A plurality of prefabricated wall bodies 3, each of the prefabricated wall bodies 3 being embedded in the mounting groove 2 and connected with each other, wherein a gap part 4 matching the first deformation joint is arranged between the two adjacent prefabricated wall bodies 3 on both sides of the first deformation joint, a second flexible sealing layer 5 being arranged in the gap part 4, and a recess 6 being provided on the opposite side of each of the remaining two adjacent prefabricated wall bodies 3 along the vertical direction, and the recess 6 being filled with a sealing material; and

[0034] A connecting support part 7 connecting the base 1 with the prefabricated wall body 3, and the connecting support part 7 having an inclined surface.

[0035] Specifically, during construction, first, the base 1 is constructed, the base 1 is poured on the top surface of the concrete face dam, a first deformation joint matching the panel blocks and a mounting groove 2 are reserved on the base 1, a first flexible sealing layer is installed in the first deformation joint, then the wall bodies 3 are prefabricated in the prefabrication yard, each wall body 3 is poured and the size specification is ensured to meet the requirements, after being transported to the site, each prefabricated wall body 3 is embedded in the mounting groove 2 in sequence, a matching gap part 4 is left between the adjacent prefabricated wall bodies 3 located on both sides of the first deformation joint and a second flexible sealing layer 5 is installed, the recesses 6 on the opposite sides of the remaining adjacent prefabricated wall bodies 3 are filled with sealing materials, and then the prefabricated wall bodies 3 are connected; finally, the connecting support part is constructed, so that the prefabricated wall bodies 3 and the base 1 are connected into an integrated whole.

[0036] It should be noted that during the operation of the concrete face dam, the panel will deform due to factors such as temperature change and dam body settlement. The base 1 of the wave protection wall is provided with a first deformation joint matching the panel blocks, when the panel deforms, the first deformation joint can provide a deformation space for the wave protection wall, so that the wave protection wall can adjust accordingly following the deformation of the panel, avoiding the occurrence of stress concentration at the panel blocks, and preventing the wave protection wall structure from being damaged due to excessive stress. The first flexible sealing layer provided in the first deformation joint and the second flexible sealing layer 5 in the gap part 4 between the adjacent prefabricated wall bodies 3 on both sides of the first deformation joint jointly play a waterproof role. The flexible sealing layer generally uses rubber plates and other materials, which have good elasticity and sealing performance, and can tightly fill the space of the deformation joint and the gap part 4 to prevent water penetration. The recesses 6 opened on the opposite sides of the remaining adjacent prefabricated wall bodies 3 are filled with sealing materials, further enhancing the waterproof effect, effectively preventing water from penetrating into the dam body from multiple parts, reducing the dam seepage risk, and protecting the dam structure. The prefabricated wall bodies 3 are embedded in the mounting groove 2 of the base 1, and the prefabricated wall bodies 3 are connected to each other, further enhancing the structural strength of the whole wave protection wall. The connecting support part 7 has an inclined surface and includes first connecting steel bars 9, second connecting steel bars 10 and concrete blocks connected to each other, the first connecting steel bars 9 are connected to the top surface of the base 1, the second connecting steel bars 10 are connected to the prefabricated wall bodies 3, and the triangular area formed between them is filled with concrete to form concrete blocks. This not only firmly connects the base 1 and the prefabricated wall bodies 3 together, but also the triangular structure has high stability, which can effectively resist external loads such as wind wave impact, stress caused by uneven settlement of the dam body, etc., avoid relative displacement between the prefabricated wall bodies 3, and ensure the stability and safety of the whole wave protection wall.

[0037] The wave wall structure of the concrete face rockfill dam proposed in the above embodiment can effectively adapt to the deformation of the face slab caused by temperature changes, dam settlement, etc., avoid stress concentration at the block, prevent structural damage, and greatly improve the waterproof performance of the wave wall structure to prevent water leakage and erosion of the dam. At the same time, by embedding the prefabricated wall 3 in the installation groove 2 and connecting each other, and adding the effect of the connecting support part 7, the tightness of the connection of each part is enhanced, effectively resisting the influence of external load and dam deformation, avoiding relative displacement between the prefabricated walls 3, and overall solving the problem that the existing wave wall cannot adapt to the stress change at the block of the face slab, ensuring the safe and stable operation of the dam.

[0038] Due to the large number of joints of the prefabricated wall 3, if not handled properly, water will seep through the joints into the dam body, not only reducing the anti-seepage effect of the dam, but also possibly eroding the dam structure over a long period of time, causing safety hazards. Therefore, as a kind of implementable way, referring to Figure 4 , one side of the two adjacent prefabricated walls 3 on both sides of the first deformation joint away from the connecting support part 7 is coated with a waterproof layer 8, and the waterproof layer 8 extends towards the top surface of the concrete face rockfill dam.

[0039] Specifically, the waterproof layer 8 extending to the top surface of the concrete face rockfill dam is arranged on one side of the two adjacent prefabricated walls 3 on both sides of the first deformation joint away from the connecting support part 7, which can effectively compensate for the defect of easy leakage of the prefabricated wall 3 joints, and enhance the overall waterproof performance of the wave wall. This not only reduces the risk of water seeping into the dam body, maintains the anti-seepage effect of the dam, but also avoids long-term erosion of the dam structure, ensures the safety and stability of the dam structure, and improves the reliability and durability of the wave wall.

[0040] As a kind of implementable way, referring to Figures 1 to 3 , the connecting support part 7 includes a first connecting steel bar 9, a second connecting steel bar 10 and a concrete block, the first connecting steel bar 9 is connected with the top surface of the base 1 and is arranged inclined upward, the second connecting steel bar 10 is connected with one side of the prefabricated wall 3 and is arranged inclined downward, the first connecting steel bar 9 is connected with the second connecting steel bar 10, a triangular area is formed between the base 1, the prefabricated wall 3, the first connecting steel bar 9 and the second connecting steel bar 10, and the triangular area is filled with concrete to form a concrete block.

[0041] Specifically, the first and second connecting steel bars 10 are used to connect the base 1 and the prefabricated wall 3, respectively, and form a triangular area between them by being arranged obliquely, and then filled with concrete to form a stable concrete block. In this way, the base 1 and the prefabricated wall 3 are closely connected, and the triangular structure stability is used to disperse and withstand external forces. The stability of the overall structure of the wave protection wall is enhanced, so that the wave protection wall can better resist wind and wave impact, dam settlement and other external forces, reduce the relative displacement between the prefabricated wall 3 and the base 1, avoid structural damage caused by loose connection, and improve the safety and durability of the wave protection wall, ensuring the safe operation of the dam.

[0042] As an implementable manner, referring to Figure 2 and Figure 3 , the first and second connecting steel bars 9 and 10 are arranged in long and short staggered manner, and the long and short distribution of the first and second connecting steel bars 9 and 10 is arranged in staggered manner.

[0043] It should be noted that the long and short distribution of the first and second connecting steel bars 9 and 10 is arranged in staggered manner, which means that the long steel bar of the first connecting steel bar 9 corresponds to the short steel bar of the second connecting steel bar 10, and the short steel bar of the first connecting steel bar 9 corresponds to the long steel bar of the second connecting steel bar 10.

[0044] Specifically, the first and second connecting steel bars 9 and 10 are arranged in long and short staggered manner and long and short distribution is arranged in staggered manner, which can significantly improve the connection strength and stability of the connecting support part 7. This arrangement increases the connection points and contact area between the steel bars, making the force transmission more uniform and dispersed. When bearing external forces, the long and short staggered steel bars can work cooperatively to effectively avoid stress concentration, enhance the connection stability of the prefabricated wall 3 and the base 1, better resist the effects of dam deformation, wind and wave impact and other external forces, and further improve the reliability and durability of the entire wave protection wall structure.

[0045] As an implementable manner, the first and second connecting steel bars 9 and 10 are connected by welding.

[0046] Specifically, the first and second connecting steel bars 9 and 10 are connected by welding, which can form a firm and stable connection node, effectively enhancing the overall mechanical properties of the connecting support part 7. Welding makes the force transmission between the two steel bars more direct and efficient, which can significantly reduce the displacement and loosening risk of the steel bar connection when resisting wind and wave impact, dam uneven settlement and other external forces, and ensure the stability of the connection between the prefabricated wall 3 and the base 1.

[0047] As an implementable manner, referring to Figure 1 and Figure 2 , the side of the mounting groove 2 facing away from the connecting support part 7 is provided with a reserved groove 11 along the dam axis direction, and the reserved groove 11 is arranged obliquely, and the reserved groove 11 is filled with a filling material.

[0048] Specifically, the reserved groove 11 can provide installation space for the prefabricated wall 3, facilitating the embedding of the prefabricated wall 3 into the installation groove 2. Meanwhile, after filling the reserved groove 11 with filling material, the prefabricated wall 3 can be more tightly connected with the base 1, thereby enhancing the integrity of the wave protection wall.

[0049] As an implementable manner, referring to Figure 1 , each prefabricated wall 3 is welded by a steel connecting plate.

[0050] Specifically, the steel connecting plate itself has high strength, providing reliable support for wall connection, and the welding method makes the connection tight and firm, reducing the gap and displacement between the walls. When facing external forces such as wind and wave impact, dam settlement deformation, etc., each prefabricated wall 3 can form a stable connection by means of the steel connecting plate welding, thereby effectively dispersing stress and avoiding damage to the prefabricated wall 3 due to excessive local stress, ensuring the long-term stability of the wave protection wall in preventing wave overtopping and protecting the dam crest safety.

[0051] As an implementable manner, referring to Figure 1 , the wave protection wall structure further comprises a railing 13, and a pre-embedded part is arranged on the base 1, and the pre-embedded part is connected with the railing 13.

[0052] Specifically, the railing 13 can effectively block personnel from accidentally approaching the dam edge, reducing the risk of falling and ensuring the safety of personnel activities on the dam crest. At the same time, it is connected with the pre-embedded part of the base 1, which is more stable than ordinary installation methods, and is not easy to loosen and shift even in harsh environments such as strong wind and vibration, thereby enhancing the safety of the railing 13 itself.

[0053] As an implementable manner, the first and second flexible sealing layers 5 are both rubber plates.

[0054] Specifically, the rubber plate has good elasticity and flexibility, and can tightly fit the gap surface between the first deformation joint and the prefabricated wall 3 gap part 4, effectively preventing water leakage. When the dam deforms due to temperature changes, settlement, etc., the rubber plate can deform with it, continuously maintaining the sealing effect, preventing water from penetrating into the dam body, avoiding the erosion of the dam structure by water, ensuring the anti-seepage performance and structural safety of the dam, and prolonging the service life of the wave protection wall and the dam.

[0055] As an implementable manner, the sealing material adopts plastic filler, and the waterproof layer 8 adopts polyurea composite tire base cloth.

[0056] Specifically, the plastic filler has good plasticity and adhesion, can tightly fill the grooves 6 of the prefabricated wall 3, and effectively prevent water from seeping from the gap between the walls. The polyurea composite tire base cloth forms a strong and durable waterproof layer 8 by virtue of the high waterproofness of polyurea and the high strength of the tire base cloth. It not only resists rain and splashes, but also prevents ultraviolet rays and chemical substances from eroding, prolongs the service life of the wave protection wall, and ensures the dam seepage effect.

[0057] For example, during the construction of the concrete face dam wave protection wall structure, first, the cast-in-place base 1 is cast on site, and the prefabricated wall 3 is prefabricated in the prefabrication yard. The concrete pouring amount of each prefabricated wall 3 is about 6.1 m 3 , and the total weight is about 15.5 t. The prefabricated wall 3 is approximately a cuboid with a length of 3 m and a thickness of 50 cm. After the prefabricated wall 3 is transported to the construction site, it is installed by hoisting operation. After the first prefabricated wall 3 is hoisted into place, 4-6 welding points are formed by welding the second connecting steel bars 10 of the first prefabricated wall 3 to the first connecting steel bars 9 of the corresponding base 1. Then, the reserved groove 11 is filled with C25 fine stone concrete to ensure that the wall verticality meets the design requirements. Then, the second prefabricated wall 3 is hoisted and placed in the 60 cm wide installation groove 2 of the cast-in-place base 1. GB plastic filler is filled in the 60 mm*80 mm groove 6 between the two prefabricated walls 3, and 4-6 welding points are formed by welding the second connecting steel bars 10 of the second prefabricated wall 3 to the first connecting steel bars 9 of the corresponding base 1. Among them, the inclination angle of the first connecting steel bars 9 and the second connecting steel bars 10 is set to 45°. At the same time, the steel connecting plates on the first and second prefabricated walls 3 are welded, and concrete is poured in the triangular area formed by the prefabricated wall 3, the base 1, the first connecting steel bars 9 and the second connecting steel bars 10. After the concrete solidifies, the subsequent prefabricated wall 3 hoisting construction is carried out in sequence according to the above process. After the installation of the prefabricated wall 3 is completed, the polyurea composite tire base cloth with a thickness of 4 mm and a width of 45 cm is used as the waterproof layer 8 on the side of the two adjacent prefabricated walls 3 away from the connecting support part 7 on both sides of the first deformation joint by using the SK scraping method; the rubber plate with a width of 50 cm and a thickness of 12 mm is used as the first and second flexible sealing layers 5 to complete the joint treatment between the base 1 and the prefabricated wall 3. Finally, the upstream side rail 13 of the base 1 is constructed and installed, and the construction of the entire concrete face dam wave protection wall structure is completed.

Any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
