Description

Technical Field

[0001] This utility model relates to plastic engineering technology products, especially protective components used in water conservancy construction. Background Technology

[0002] China invests heavily in water conservancy projects annually, with the specific amount varying depending on national policies, economic development needs, and annual plans. In 2021, China's investment in water conservancy construction reached approximately 757.6 billion yuan, a record high. Investment in water conservancy construction continued to grow in 2022, exceeding 1 trillion yuan for the first time. Going forward, investment in water conservancy construction is expected to remain high annually, with a focus on flood control and disaster reduction, water resource allocation, and water ecological restoration.

[0003] Plastic products have appeared on embankments, rivers, and farmland. Due to their high production efficiency, simple assembly methods, and reusability, they are used in many situations. However, their mechanical strength is insufficient, and they may deform or be damaged when subjected to large water pressure, impact, or loads. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic protective component for water conservancy projects with high mechanical strength and resistance to deformation.

[0005] The technical solution of this utility model is designed as follows: it has a bottom surface, which is not a straight strip, that is, it has bends, with no less than two bends and multiple annular closed structures are provided on the bottom surface. The left and right sides of the bottom surface are provided with concave and convex connecting structures that can cooperate with each other. The bottom surface and the concave and convex connecting structures on its left and right sides all extend upward to the required height.

[0006] To enhance the product's mechanical properties, the distance between the two annular closed structures should be between 20-100 cm. It is preferable to place the annular closed structures at or near bends, as this provides both bending resistance and improved stability.

[0007] The orthographic projection of the aforementioned annular closed structure can be a geometric shape such as a triangle, a circle, or a quadrilateral.

[0008] With this structural design, when used for water blocking, waterproof strips can be installed on the connecting structures on both the left and right sides. Multiple waterproof strips can be installed for better waterproofing. Of course, to achieve waterproofing, the waterproof strips should be interference-fitted when connecting.

[0009] The plastic protective components for water conservancy projects described above can be produced through extrusion molding, which has high production efficiency. The combination of a ring-shaped closed structure and multiple waterproof strips significantly improves the mechanical strength, deformation resistance, and waterproof performance of the protective components. In actual construction, the ring-shaped closed structure can be used to backfill part of the riverbank mud, or to fill mud or cement, further enhancing the stability and lateral bending resistance of the protective components.
