Detailed Implementation

[0015] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0016] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1: Reference Figure 1-5A rapid-assembly river flood control retaining wall includes mounting columns 1, a first flood control wall 2, and a second flood control wall 3. The sides of the first flood control wall 2 and the second flood control wall 3 are respectively inserted into the surface of the mounting column 1. The sides of the first flood control wall 2 and the second flood control wall 3 are interlocked. The mounting column 1, as the core support structure of the entire flood control retaining wall system, ensures the stable positioning of the two flood control retaining walls by interlocking with the sides of the first flood control wall 2 and the second flood control wall 3, resisting the impact of floods and maintaining the stability of the overall structure. The flood control wall 3 forms a continuous flood barrier by interlocking with the mounting column 1 on its side, bearing the flood pressure and protecting the river channel. The first flood control wall 2 has a guide groove 16 on its side, with toothed grooves 17 inside. The first flood control wall 2 also has a trapezoidal groove 18 on its side. The second flood control wall 3 has a guide block 13 on its side, with toothed blocks 14 on its side and trapezoidal blocks 15 on its side. The guide block 13 is dovetail-shaped, and its shape and position are aligned with the guide... The guide groove 16 is adapted to the guide block 14, and the shape and position of the toothed block 14 are adapted to the toothed groove 17. The shape and position of the trapezoidal block 15 are adapted to the trapezoidal groove 18. The guide groove 16 cooperates with the guide block 13, and the guide block 16 slides into the guide groove 13 to ensure that the two flood control retaining walls are accurately aligned during splicing, preventing misalignment, significantly improving assembly efficiency and simplifying operation. The toothed groove 17 is set inside the guide groove 16 and precisely engages with the toothed block 14 on the side of the guide block 13 to form a load-bearing structure similar to a tenon and mortise, which not only strengthens the positioning effect but also increases the load through the engagement. The shear resistance of the connection points enhances the stability of the overall structure and prevents sliding or separation caused by flood impact. The trapezoidal groove 18 and trapezoidal block 15 form a sealing step through a matching labyrinthine bending design, forcing water to detour through a complex path during infiltration, significantly reducing the risk of leakage, enhancing waterproof performance, and protecting the overall sealing of the retaining wall. At the same time, a sealing strip is installed in the trapezoidal groove 18. The two work together to further improve the sealing performance. The sides of the first flood control wall 2 and the second flood control wall 3 are provided with a first fixing pin 11. The first fixing pin 11 passes through the trapezoidal block 15 on the first flood control wall 2 and the second flood control wall 3, further locking the two flood control retaining walls and preventing the splicing parts from loosening or separating due to flood impact, thereby improving the overall structural strength.

[0018] The first flood control wall 2 and the second flood control wall 3 have fixing grooves 6 on their sides. A reinforcing plate 4 is provided on the surface of the fixing groove 6. A slot 7 is provided on the side of the fixing groove 6. A rubber strip 9 is provided on the surface of the slot 7. Inserts 8 are provided on the side and bottom of the reinforcing plate 4, and the shape and position of the inserts 8 are adapted to the slots 7. The fixing grooves 6 are located on both sides of the flood control retaining wall to accommodate the reinforcing plate 4. The slots 7 are located on the side of the fixing groove 6 and have rubber strips 9 inside, which are adapted to the inserts 8 of the reinforcing plate 4 to ensure the reinforcing plate 4 is installed securely. 9. The reinforced slot 7 enhances the sealing performance, forming an additional sealing layer to further prevent water from seeping through the assembly gaps, thus enhancing the waterproof performance of the flood control wall. It also reduces erosion and corrosion at the joints. The reinforcing plate 4, through its side and bottom inserts 8, is inserted into the slot 7 within the fixing groove 6, tightly bonded to the rubber strip 9, forming an additional protective layer. This not only effectively blocks the assembly gaps between the first flood control wall 2 and the second flood control wall 3, preventing water seepage and erosion, but also increases the rigidity and load-bearing capacity of the connection points through its front and rear side installations. To improve the deformation resistance of the retaining wall and prevent it from warping or collapsing due to long-term water pressure, the reinforcing plate 4 is further fixed to the surface of the flood control retaining wall in conjunction with the locking mechanism of the reinforcing cover 5 and the limiting block 10, ensuring long-term reliability under high water pressure. The surface of the first flood control wall 2 and the second flood control wall 3 is provided with the reinforcing cover 5, and the surface of the reinforcing cover 5 is provided with the second fixing pin 12. The top surface of the reinforcing plate 4 is provided with the limiting block 10. The shape and position of the reinforcing cover 5 are adapted to the reinforcing plate 4 and the limiting block 10. The reinforcing cover 5 covers the first flood control wall 2. The top surface of the second flood control wall 3 has a limiting groove on its bottom surface, the shape and position of which are adapted to the limiting block 10. It is fixed to the first flood control wall 2 and the second flood control wall 3 by the second fixing pin 12, which further ensures that the reinforcing plate 4 is firmly in place, enhances the impact resistance of the connection part, and prevents deformation or collapse caused by flood pressure. The limiting block 10 cooperates with the reinforcing cover 5 to further enhance the stability of the connection part by restricting the up and down movement of the reinforcing plate 4, and ensures the stability of the reinforcing plate 4 and the overall structure of the flood control wall under the impact of flood. Specific Implementation Example 2: A rapid-assembly river flood control retaining wall, based on the basic structure in Specific Embodiment 1, further discloses the following: The operation of the rapid-assembly river flood control retaining wall is as follows: First, the installation column 1 is fixed at a predetermined position in the river channel as the supporting foundation for the entire flood control system. Next, the sides of the first flood control wall 2 and the second flood control wall 3 are interlocked. Guide blocks 13 are slidably inserted along the guide groove 16 on the side of the first flood control wall 2 to ensure rapid alignment of the two flood control walls. The toothed grooves 17 in the guide groove 16 precisely engage with the toothed blocks 14 on the side of the guide block 13, strengthening positioning and shear resistance. Simultaneously, the trapezoidal blocks 15 on the side of the second flood control wall 3 are inserted into the trapezoidal grooves 18 of the first flood control wall 2, forming a labyrinthine sealing step. This, combined with the sealing strips in the trapezoidal grooves 18, effectively prevents leakage. Subsequently, the... The first fixing pin 11 passes through the trapezoidal block 15 on the first flood control wall 2 and the second flood control wall 3 to lock the two flood control walls, further enhancing the connection stability. Then, the insert block 8 of the reinforcing plate 4 is inserted into the slot 7 in the fixing groove 6, and tightly combined with the rubber strip 9 in the slot 7 to cover the assembly gap and improve the waterproof performance. The reinforcing plate 4 can be installed on both the water-facing side and the back water-facing side to form a "sandwich" protection, enhancing the impact resistance and deformation resistance. Finally, the reinforcing cover 5 is installed to cover the top surface of the flood control wall. Its bottom limiting groove is adapted to the limiting block 10 on the top surface of the reinforcing plate 4. The reinforcing cover 5 is fixed by the second fixing pin 12 to lock the reinforcing plate 4, ensuring the stability and long-term durability of the overall structure, completing the rapid assembly and reinforcement operation. Then, the assembled flood control wall is installed with the installation column 1.

[0020] In summary: The system employs guide blocks 13, trapezoidal blocks 15, reinforcing plates 4, first fixing pins 11, and second fixing pins 12. Guide blocks 13 and guide grooves 16 are fitted with a dovetail structure. Guide blocks 13 are installed along guide grooves 16 to ensure rapid alignment of the first flood control wall 2 and the second flood control wall 3 during assembly, preventing misalignment. The toothed grooves 17 within the guide grooves 16 precisely engage with the toothed blocks 14 on the sides of the guide blocks 13, achieving not only positioning but also enhancing shear resistance and improving the structural stability of the connection. Simultaneously, trapezoidal blocks 15 and trapezoidal grooves 18 form a sealing step, employing a labyrinthine bending design to facilitate water flow. During infiltration, a complex path must be taken to further enhance the sealing effect and effectively prevent leakage risks in the assembly gaps. The first fixing pin 11 further fixes the first flood control wall 2 and the second flood control wall 3. In addition, the reinforcing plate 4 is inserted into the slot 7 in the fixing groove 6 through the insert block 8 and tightly combined with the rubber strip 9 to cover the assembly gaps and improve the overall waterproof performance. The second fixing pin 12, together with the limiting block 10, locks and reinforces the reinforcing plate 4, significantly enhancing the impact resistance of the connection parts and effectively resisting the risk of deformation or collapse under flood pressure, thereby ensuring the overall stability and long-term durability of the flood control retaining wall.
