High chloride ion levels and salt crystallization and accumulation easily damage plastic-steel sheet piles, cause locking seal failure and structural degradation, which undermines the stability and service life of retaining structures. To strengthen anti-salt-corrosion measures and guarantee long-term project safety, key operation guidelines are sorted out as follows.<\/div>\n<\/div>\n<div>\n<h4>1. Material Selection<\/h4>\n<\/div>\n<div>\n<div>Fiberglass-reinforced, salt-corrosion-resistant modified plastic-steel sheet piles customized for high-chloride coastal settings shall be prioritized. Non-standard and unmodified ordinary products are strictly forbidden. Upon delivery, piles shall have intact dense surfaces without damage and complete protective coatings. All connecting fittings shall be made of stainless steel or corrosion-resistant plastic steel to rule out corrosion risks from carbon steel accessories.<\/div>\n<\/div>\n<div>\n<h4>2. Anti-Corrosion Control During Construction<\/h4>\n<\/div>\n<div>\n<div>\n<p>Strict anti-corrosion details shall be enforced throughout construction. Piles shall be stored on raised supports to avoid dampness, salt fog erosion and ponding. Before installation, thoroughly clean interlocking joints and evenly apply coastal anti-corrosion sealant and waterproof expanding resin. Re-coat the sealant after assembly to block all water seepage paths.<\/p>\n<div><\/div>\n<p>Adopt flexible lifting methods and standardized piling procedures to prevent scratches on the protective coating and pile deformation. Repair damaged areas immediately and optimize site drainage to stop salt crystal buildup.<\/p>\n<\/div>\n<\/div>\n<div>\n<h4>3. Zoned Maintenance &amp; Protection<\/h4>\n<\/div>\n<div>\n<div>\n<p>Carry out maintenance on a zonal basis. For severely corrosive zones such as tidal zones and splash zones, overlay salt-resistant epoxy or polyurethane coatings on the base protection layer. Install FRP (fiberglass-reinforced plastic) anti-corrosion layers where needed, with extra reinforcement on vulnerable parts including corners and joints.<\/p>\n<div><\/div>\n<p>Set up regular maintenance routines: flush piles with fresh water periodically to remove salt and scale, inspect for coating aging and seal failure, and conduct timely repairs. A full anti-corrosion refurbishment shall be implemented every 7 to 10 years in high-salt environments to maintain lasting protection.<\/p>\n<\/div>\n<\/div>\n<div>\n<h4>4. Overall Engineering Application Principles<\/h4>\n<\/div>\n<div>\n<div>\n<p>Avoid common pitfalls in engineering: do not overemphasize material selection over construction, or construction over maintenance; never mix non-standard components or operate with hidden risks.<\/p>\n<div><\/div>\n<p>Salt corrosion protection for plastic-steel sheet piles must run through the whole lifecycle \u2014 from material procurement and construction to on-site protection and daily maintenance. This comprehensive system can fully mitigate salt-induced damage and reliably secure the stability and durability of coastal tidal flat retaining projects.<\/p>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Coastal tidal flats feature high salinity, high humidity and repeated wet-dry tidal alternations.
