AI Technical Summary
Steel pipe piles for temporary steel bridges are prone to corrosion under high humidity, salt spray erosion, and tidal wave action, especially the inner wall is difficult to prevent corrosion, and traditional anti-corrosion measures are insufficient.
Design a steel pipe pile top sealing device for a temporary steel bridge, including a pile top cover plate and supporting components. The top of the steel pipe pile is mechanically isolated by a sealant filling layer and supporting components, and the main beam of the temporary steel bridge is supported by bolts to enhance the overall integrity.
It effectively prevents seawater and rainwater from entering the interior of the steel pipe pile, avoids internal wall corrosion, disperses the pressure on the main beam, and improves the corrosion resistance of the steel pipe pile.
