在观音岩水电站溢流坝段溢流面施工中，由于结构设计、施工工艺等原因，致使部分混凝土存在Ⅰ类裂缝、麻面、气泡、划痕及墙根缝等质量缺陷。根据现场条件并结合相关工程经验，最终选择MS－3环氧系列材料对缺陷进行了修补。介绍了MS－3环氧系列材料的基本性能、配比及使用方法，对各类缺陷具体修补流程的施工工艺进行了详细论述。缺陷修补完成后，与老混凝土结合紧密，锤击声音清脆，满足设计要求。
在觀音巖水電站溢流壩段溢流麵施工中，由于結構設計、施工工藝等原因，緻使部分混凝土存在Ⅰ類裂縫、痳麵、氣泡、劃痕及牆根縫等質量缺陷。根據現場條件併結閤相關工程經驗，最終選擇MS－3環氧繫列材料對缺陷進行瞭脩補。介紹瞭MS－3環氧繫列材料的基本性能、配比及使用方法，對各類缺陷具體脩補流程的施工工藝進行瞭詳細論述。缺陷脩補完成後，與老混凝土結閤緊密，錘擊聲音清脆，滿足設計要求。
