In riverbank protection and excavation shoring projects, Z-shaped ecological sheet piles have become the preferred solution for balancing engineering safety and environmental protection requirements due to their unique structural advantages and ecological properties, and are widely used in various river management projects. These sheet piles feature a “Z”-shaped cross-section, consisting of parallel flanges and a central web. Through interlocking joints, they form a continuous retaining wall that combines multiple functions, including earth retention, water retention, and ecological protection.
Compared to traditional support materials, Z-shaped ecological sheet piles offer high cross-sectional stiffness and outstanding bending and shear resistance. Their bending load-bearing capacity is 20%–30% higher than that of ordinary sheet piles, enabling them to effectively withstand earth pressure, water pressure, and water erosion during riverbank excavation, thereby ensuring slope stability. Their interlocking design ensures a tight seal and excellent impermeability, reducing groundwater infiltration and lowering dewatering costs for excavation pits. They are suitable for a variety of geological conditions, including soft soil and sandy soil.
In practical applications, the length and layout of Z-type ecological sheet piles can be flexibly adjusted based on excavation depth and geological conditions. When integrated with a support system, they form a stable retaining structure that effectively addresses stability and ecological protection challenges during riverbank excavation. This provides reliable support for the safe, efficient, and environmentally friendly implementation of river management projects.
