In water conservancy projects such as river channel remediation, embankment reinforcement, and wharf revetment, the corrosion resistance and scour resistance of plastic steel sheet piles are fully utilized. For instance, in river ecological restoration projects, plastic steel sheet piles are used to construct ecological revetments. These structures not only provide flood control and slope stabilization but also incorporate pre-designed permeable holes or planting slots. These features create habitats for aquatic organisms and plants, achieving an organic integration of engineering protection and ecological conservation. In coastal breakwater construction, their resistance to seawater corrosion enables them to withstand long-term wave erosion, with a service life exceeding 50 years.

2. Municipal Infrastructure Projects

Plastic steel sheet piles play a vital role in municipal engineering applications such as foundation pit support, underground utility tunnel construction, and sewage tank leak prevention. In deep foundation pit projects like urban subway stations and underground shopping malls, these lightweight yet high-strength piles serve as temporary support structures, facilitating rapid construction.
