Urban river dredging and rehabilitation is a crucial measure for improving water quality and restoring ecological functions. Temporary water-retaining barriers, as a core component of construction, must be adapted to the characteristics of urban river construction sites, which feature limited space and stringent environmental requirements. Traditional water-retaining materials suffer from issues such as cumbersome installation, poor impermeability, and susceptibility to causing secondary pollution, making them inadequate for construction needs.
As a new eco-friendly polymer composite material, plastic steel sheet piles have emerged as the ideal solution for this scenario. Combining corrosion resistance, impermeability, and high strength, the assembled water-retaining walls provide excellent sealing, effectively isolating silt from clean water bodies to prevent secondary water quality deterioration. Moreover, the material is environmentally friendly and non-polluting, aligning perfectly with the ecological restoration requirements of inland rivers. Furthermore, its lightweight design eliminates the need for heavy construction equipment, enabling rapid installation and removal. It adapts seamlessly to confined workspaces, significantly shortening project timelines. Post-construction, the material can be recycled and reused, reducing both project costs and environmental impact.
In urban river dredging projects, plastic steel sheet piles leverage their environmental friendliness, efficiency, convenience, and durability to provide reliable support for temporary water-retaining structures. This facilitates efficient dredging operations and advances the ecological goal of achieving clear waters and green banks in urban rivers.
