Cost Control for Anticorrosion of Maocaojie-bridge Steel Tube Arch Structure

Maocaojie-bridge is a middle supporting arch bridge composed of steel tube and concrete system.The arc-spraying anticorrosion technique was applied to the steel structure surface．Although arc-spraying anticorrosion technique has applied broadly, the construction cost control is a crucial problem in many anticorrosion construction units．This paper dissertates the direct cost of anticorrosion construction in inner and outer surfaces of Maocaojie-bridge steel tube arch,and discusses how to control construction cost in arc-spraying anticorrosion of steel structures．
