1. Anti-corrosion Treatment In humid or corrosive environments, regularly inspect the surface of plastic steel sheet piles for signs of aging, cracks, or corrosion. If abnormalities are detected, promptly repair the anti-corrosion coating or replace the affected sections. ‌

2. Periodic Inspection Check for loosening or damage at interlocking joints to ensure tightness between sheet piles. ‌

3. Monitor special design components like ecological holes and funnel structures for blockage or deformation. Clear or adjust as necessary. ‌

4. Environmental Adaptability Maintenance Under extreme conditions (e.g., prolonged immersion, low temperatures), verify whether the plastic steel sheet piles’ elasticity and toughness are compromised. Implement reinforcement measures if required. ‌

5. Post-Installation Maintenance For installed plastic-steel sheet piles, regularly monitor verticality, elevation, and surrounding soil deformation, addressing anomalies promptly. ‌
