[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1-5As shown, a seawall reinforcement structure for a seawall slope 1 includes: an impermeable geomembrane 2, a gravel cushion layer 3, a mortar layer 4, precast concrete blocks 5, and anchor bolts 6. The impermeable geomembrane 2 is laid on the water-facing surface of the seawall slope 1. A gravel cushion layer 3 is laid on top of the impermeable geomembrane 2, and precast concrete blocks 5 are laid on top of the gravel cushion layer 3. A mortar layer 4 is provided between the precast concrete blocks 5 and the gravel cushion layer 3. The precast concrete blocks 5 are fixed to the seawall slope 1 by the anchor bolts 6. Four wave-dissipating blocks 50 are provided on the surface of the precast concrete blocks 5. Two flanges 51 and two grooves 52 are respectively provided on the sides of each precast concrete block 5. The grooves 52 are respectively located on adjacent sides of the precast concrete blocks 5, and the flanges 51 are respectively located on opposite sides of the grooves 52. The shapes of the flanges 51 and the grooves 52 are compatible. The precast concrete blocks 5 are factory-produced, ensuring quality control. The flanges 51 and grooves 52 on its sides allow adjacent precast blocks to quickly and accurately interlock and splice each other, which not only improves construction efficiency and simplifies the installation process, but more importantly, it connects the scattered precast blocks into a more integrated continuous protective surface, which can jointly bear external forces and improve the overall stability of the structure.

[0021] The precast concrete block 5 has two perpendicular water passage holes 53, which are respectively located inside the two flanges 51. The water passage holes 53 facilitate the rapid discharge of water during wave impact, reducing the buoyancy force and dynamic water pressure acting on the protective layer, and further enhancing the stability and energy dissipation effect of the structure.

[0022] The precast concrete block 5 has an installation hole 54 in the middle. The anchor rod 6 passes through the installation hole 54, penetrates the mortar layer 4, the gravel cushion layer 3, and the impermeable geomembrane 2, and is inserted into the seawall slope 1. The upper end of the anchor rod 6 has a thread 60, the bottom of the anchor rod 6 has a spike 61, and the lower end of the anchor rod 6 has a barb 62. A nut 63 is screwed onto the thread 60, and the nut 63 is pressed tightly onto the surface of the precast concrete block 5. The anchor rod 6 firmly anchors the precast concrete block 5, the mortar layer 4, the gravel cushion layer 3, and the impermeable geomembrane 2 to the seawall slope 1, forming a synergistic force-bearing whole. The spike 61 and barb 62 at the bottom of the anchor rod 6 are designed to anchor deeper into the soil and provide strong pull-out resistance, while the thread 60 and nut 63 at the upper end ensure pre-tightening force and connection reliability.

[0023] The wave-damping block 50 is shaped like a regular square truncated pyramid. It can effectively break up incoming waves, dissipate wave energy, and reduce the scouring force of waves during their rise and fall.

[0024] It also includes a waterproof sleeve 64, which is fitted over the top outer side of the anchor rod 6 and the nut 63. The waterproof sleeve 64 is a rubber sleeve.

[0025] A sealing ring 65 is provided between the nut 63 and the precast concrete block 5. This effectively prevents seawater from seeping into the dike body through the anchor bolt installation hole, avoids corrosion of the anchor bolt 6, significantly extends the service life of key anchoring components, and ensures the long-term effectiveness of the reinforcement.

[0026] The installation steps of this utility model are as follows: First, the water-facing slope of the seawall slope 1 that needs to be reinforced is repaired and compacted, and sharp debris such as gravel and tree roots are removed from the surface; the impermeable geomembrane 2 is laid from top to bottom on the treated slope surface. During laying, it should be kept flat and taut to avoid wrinkles and damage. Sufficient overlap width should be left between adjacent geomembrane rolls, and they should be effectively connected using special welding equipment or adhesive to form a complete impermeable layer. The position of the installation hole 54 is calculated, and the hole is drilled downwards using a drilling rig. The drill bit needs to penetrate the seawall slope 1 to the designed depth. After cleaning the hole, the anchor rod 6 is inserted into the hole, and the edge of the opening of the impermeable geomembrane 2 is sealed with special sealant or adhesive to prevent leakage; a sand and gravel cushion layer 3 is evenly laid on the laid impermeable geomembrane 2; a mortar layer 4 is laid on the compacted sand and gravel cushion layer 3; and precast concrete blocks 5 are assembled and laid one by one from the slope foot to the slope top on the unhardened mortar layer. 4. During assembly, ensure that the flanges 51 and grooves 52 on the sides of the precast concrete blocks 5 interlock to form a tight fit between the blocks, creating a robust protective surface layer. During assembly, ensure that the water holes 53 on the precast blocks are aligned to form an effective drainage channel. Pass the top of the anchor rod 6 through the pre-drilled installation hole 54 on the precast concrete block 5, ensuring that the threaded portion 60 at the top of the anchor rod 6 protrudes sufficiently from the surface of the precast concrete block 5. First, install a sealing ring 65 on the exposed thread 60 of the anchor rod 6, then tighten the nut 63. Use a torque wrench or similar tools to tighten the nut 63 according to the design requirements, providing pre-tightening force to the entire reinforcement structure and pressing it firmly against the seawall slope 1. Finally, cover the tightened nut 63 and the top of the anchor rod 6 with a waterproof sleeve 64 and seal it (e.g., by adhesive or hot-melt bonding) to form the final anti-corrosion and anti-seepage barrier, preventing seawater from seeping in through the anchor rod hole and corroding the anchor rod 6.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
