Aiming at the diseases of cement concrete crash barrier of Yellow River Highway Bridge in Huiqing of Shandong, the overall scheme for the reinforcement and construction of enhanced polycarbosiloxane anticorrosive coating is prepared. The properties and advantages of RBS high-elastic macromolecule anticorrosive waterproof coating, SHJS polycarbosiloxane anticorrosive coating and SHJS high-polymer carbon steel repair material are introduced. The construction technologies and quality control essentials of enhanced polycarbosiloxane anticorrosive coating are set forth and summarized. After the barrier is reinforced and repaired, it is found that the barrier is in good condition, and the expected effect of the maintenance scheme is achieved through the observation of 8 a. The special treatment of anticorrosive base and the thickening of anticorrosive coating in the maintenance scheme make the quality of the anticorrosive coating more reliable.
