基于电化学脱盐的海港工程混凝土结构修补加固方法及系统
摘要：
本发明公开了一种基于电化学脱盐的海港工程混凝土结构修补加固处理方法，其包括以下步骤：（1）对混凝土构件进行构件表面检测评估、修补和处理；（2）电化学脱盐处理；（3）根据修补时构件的状态和修补加固后使用寿命的要求确定脱盐处理后采用碳纤维加固或涂层防腐进一步提高结构的安全性或耐久性。本发明可以较彻底地清除侵入混凝土中的氯离子，从根源上保护混凝土中的钢筋；同时可以提高钢筋周围的碱性，中止钢筋的腐蚀过程。脱盐后根据构件的检测评估结果，实施环氧涂层防腐提高结构的耐久性，必要时采用碳纤维加固技术恢复结构的承载力。本发明的修补加固系统方法可以有效延长结构寿命15年以上。
摘要（英）：

The invention discloses a method for repairing, reinforcing and treating a harbour engineering concrete structure based on electrochemical desalting, which comprises the steps that: 1 the surface of a concrete member is detected, assessed, repaired and processed; 2 the concrete member is processed through electrochemical desalination; and 3 carbon fibers are determined to be used to reinforce or prevent a coating from being corroded according to the state of the concrete member when being repaired and the requirement of service life after being repaired and reinforced, thereby further increasing structure safety or durability. The method for repairing, reinforcing and treating the harbour engineering concrete structure based on the electrochemical desalting can clean chloride ions which intrude into concrete, protects steel bars in the concrete from roots, can increase alkalinity around the steel bars simultaneously, and stops the corrosion process of the steel bar. The method for repairing, reinforcing and treating the harbour engineering concrete structure based on the electrochemical desalting increases structure durability by carrying out corrosion prevention of an epoxy coating according to a detected and assessed result after desalting, and uses the carbon fiber reinforcing technology to recover structure bearing capacity in necessity. The method for repairing, reinforcing and treating the harbour engineering concrete structure based on the electrochemical desalting can prolong the structure service life above 15 years.
