We carried out two phases of corrosion repair works for liquid chemical wharf steel pipe piles respectively. The first phase of demonstration project steel pipe pile diameter 1200 mm, design pile top elevation 5 m. The diameter of the steel pipe pile in the second phase of the demonstration project is 1200 mm, and the top elevation of the design pile is 5 m; The diameter of the steel pipe pile is 1000 mm, and the top elevation of the design pile is 6 m. The total covered area of the two phases is about 500 m2.

 

The comparison before and after the repair of steel piles in liquid chemical wharf is as follows:
