摘要:研究了一種水下結構加固工藝:先安裝套筒再進行復合灌漿料灌注的方法進行施工。該方法有施工工藝簡單,工期短,施工難度小,環氧復合灌漿料與原結構表面結合度高等優點。通過在干燥、淡水和人造海水3種不同環境下的修補試驗,發現水下修補復合灌漿料在不同環境下對基材都有良好的修復效果;論述了施工工藝流程,施工物資準備、施工質量保證措施,可為水下結構加固修復施工提供經驗借鑒。
關鍵詞:環氧復合灌漿料;水下環境;加固修復施工

Abstract:An underwater structure reinforcement process was studied. The construction method is to first install a sleeve and then perform a composite grouting. The method has the advantages of simple construction process,short construction period,small construction difficulty,high bonding degree of the epoxy composite grouting material and the original structure surface. Through the repair tests under three different environments of drying,fresh water and artificial seawater,it is found that the underwater repair composite grouting material have good repairing effect to the substrates under different environments. The construction process,construction material preparation and construction quality assurance measures of this technology are also discussed,which provides experience for underwater structure reinforcement and repair construction.
Key words:epoxy composite grouting material,underwater environment,reinforcement and repair construction
