The anchor bolt is located at the bottom of the steel building. Due to structural reasons, corrosive media such as rain are easy to gather and concentrate at the anchor bolt, forming a harsh corrosion environment, which is easy to corrosion and threatens the durability and safety of the steel structure of the pipe corridor. During the simultaneous construction of the wharf, the oxidation polymerization coating anti-corrosion technology was carried out on the bolts and water storage tanks, and more than 6000 bolts were covered.
