Abstract
An anti-corrosion material and anti-corrosion method for submerged floating tunnel pipe section concrete is provided. The anti-corrosion material includes: a base layer material, a middle layer material and a surface layer material. The base layer material is an organosilicon material. The middle layer material is high-strength and high-durability fiberglass reinforced plastic. The surface layer material is a hydrophobic material. The anti-corrosion method includes: preparing fiberglass reinforced plastic; cleaning a surface of a submerged floating tunnel pipe section concrete material, preparing an organosilicon material, and coating the organosilicon material onto the surface of the pipe section concrete material; and preparing a hydrophobic material, and spray-coating the hydrophobic material onto a surface of the fiberglass reinforced plastic. The organosilicon material is adopted to improve the durability of the pipe section concrete and the bonding performance between the fiberglass reinforced plastic and the pipe section concrete.
