Plastic steel sheet piles are a new type of high-strength building material made from eco-friendly polymer-reinforced composite materials. Produced through a unique single-extrusion molding process, they incorporate multiple additives to enhance physical properties. Their design follows mechanical principles, featuring a high-moment-of-inertia cross-section paired with multi-directional interlocking joints. When assembled, they form a continuous structure with high strength and excellent lateral resistance, making them suitable for projects like ecological revetments.
Key Features and Advantages: Plastic steel sheet piles offer lightweight, high strength, corrosion resistance, and environmental sustainability with recyclability. Compared to traditional concrete or steel sheet piles, they enable more convenient construction with minimal environmental impact. Their modular design facilitates transportation and installation while providing excellent impermeability and deformation resistance.
Applications: This material is widely used in agricultural water conservancy (e.g., irrigation channels, reservoir embankment reinforcement), construction engineering (e.g., foundation pit support, slope protection retaining walls), transportation projects, disaster prevention and mitigation initiatives, and marine development. It is particularly suitable for ecological restoration projects, such as enhancing slope stability and ecological benefits through double-layer revetment designs combined with vegetation planting.
Construction Method: Installation requires initial positioning and layout. Specialized pile-driving sleeves secure the sheet piles, which are driven into the foundation using hydraulic vibratory hammers or water jets (for challenging terrains) to ensure verticality and flatness. The construction process is highly efficient, minimizing disturbance to the surrounding environment.
Market and Production: Multiple domestic enterprises specialize in the R&D and production of plastic steel sheet piles, including Haiyan Huixiang New Building Materials Technology Co., Ltd. and Tongxiang Xiaolaoban Special Plastic Products Co., Ltd. These companies typically offer customized services and technical support. Their products are listed in the national promotion catalog, reflecting industry recognition.
