The application discloses a kind of optimal filling rate calculation method of multilayer sand-filled geotextile pipe coast beach protection, belong to the technical field of coast protection engineering.The quantitative relationship between filling rate and geotextile pipe elliptical section size is established, the overall multilayer structure is taken as the research object, the anti-sliding torque and sliding torque are calculated, and the explicit function relationship between the anti-sliding stability safety factor and the filling rate is derived;Finally, the safety factor and the filling rate relationship curve is drawn, and the filling rate corresponding to the highest point of the curve is taken as the optimal filling rate.The application can scientifically and quantitatively determine the optimal filling rate of multilayer sand-filled geotextile pipe under different marine environmental conditions, effectively reduce the waste of filling material under the premise of ensuring the anti-sliding stability of the structure, significantly reduce the engineering cost, and improve the wind and wave erosion resistance and long-term service life of the structure.The method is simple, accurate and suitable for various coastal engineering such as coast protection, sea embankment protection, beach management, etc.

The utility model discloses a wave pile for bank protection, which comprises unit piles, and the adjacent unit piles are sequentially connected end to end through connecting pieces to form a wave-shaped structure; convex edge parts are arranged at the two ends of each unit pile, and limiting grooves corresponding to the connecting pieces are formed in the convex edge parts; vertical pouring grooves are formed in the two end faces of each unit pile and filled with cement mortar, so that every two adjacent unit piles are fixedly connected. The utility model has the advantages of novel structure, convenience in construction, no toppling, high stability and durability.

This invention discloses a breakwater structure for wave dissipation and shore protection, comprising a vertical box-shaped structure and a wave-dispelling nozzle block mounted on top of the box-shaped structure. Three rows of water inlets are provided on the wave-facing side of the vertical box-shaped structure. Two layers of grids are spaced apart from top to bottom within the inner cavity of the box-shaped structure, with multiple permeable holes arranged in an array on the grids. Multiple arc-shaped guide surfaces are also provided on the inner wall of the vertical box-shaped structure. These arc-shaped guide surfaces reduce the frontal impact force of each water flow on the inner wall of the vertical box-shaped structure, better promoting vertical collisions between water flows and achieving energy dissipation. The wave-dispelling nozzle block includes a base and an arc-shaped wave-dispelling nozzle structure mounted on the base. The arc-shaped wave-dispelling nozzle structure includes a vertical arm and a horizontal support arm connected to the top of the vertical arm. The wave-facing sides of the vertical arm and the horizontal support arm are provided with arc-shaped guide surfaces, which are used to guide the overrushing water back to the sea side. This invention is simple to construct, has good overall integrity, and can effectively dissipate the energy of water waves.

The utility model discloses a kind of combined revetment piles, it is related to embankment technology field, including pile body, the protrusion is provided in pile body one side, the recess is provided in another side of pile body, adjacent two pile bodies are inserted by protrusion and recess, protrusion and recess can be vertically inserted along multiple angles, so that multiple connected pile body can be enclosed arc embankment structure;It also includes cutting body, cutting body is located in the lower part of pile body;By setting the protrusion and recess of circular structure in the two sides of pile body, so that adjacent two pile bodies can be inserted along different angle and be connected, so that different shape embankment line can be formed between multiple pile bodies to adapt river bank and lake bank, effectively improve the applicability of revetment pile;Meanwhile, by setting the cutting body of assembly, the split processing of revetment pile is realized, to enrich the installation mode of pile body.
