▎ 摘　　要

NOVELTY - The pier has a spiral hole sieve type steel cylinder (6) externally sleeved with a steel pipe (2) that is externally provided with a graphene anti-corrosion coating (1). An outer layer concrete (5) is cast between the spiral hole sieve type steel cylinder and the steel pipe. The spiral hole sieve type steel cylinder is provided with a steel reinforcement cage (7), where an inner side of the spiral hole sieve type steel cylinder is poured with an inner layer concrete (8). USE - Anti-corrosion steel pipe concrete bridge pier for use in a marine building. ADVANTAGE - The pier can effectively prevent corrosion of sea water, effectively prolong service life, reduce economic loss and expand application range of the steel pipe concrete, and has high-strength. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of an anti-corrosion steel pipe concrete bridge pier for use in a marine building.
