Construction method for rapid underwater repair of leakage cracks of concrete faced rockfill dam and repair structure of construction method
The invention discloses a construction method for rapid underwater repair of leakage cracks of a concrete faced rockfill dam. The construction method for rapid underwater repair of the leakage cracksof the concrete faced rockfill dam comprises the following steps in sequence: step 1, washing is carried out from top to bottom along the cracks to ensure that the concrete base surface is washed out;step 2, the concrete base surface is washed again; step 3, even painting of a underwater epoxy cement prime coat is carried out along the cracks from top to bottom; step 4, underwater rapid sealing materials are rolled into a cylindrical shape, the materials are bagged and sent underwater; step 5, the cylindrical underwater rapid sealing materials are pressed tightly along the cracks, and it is guaranteed that the middle is thick and the two sides are thin after pressing; step 6, after a flexible surface protection layer is spread underwater along the cracks, a fixed structure is used for fixing the flexible surface protection layer to the concrete base surface; step 7, after all procedures are completed, the treatment area is checked. The construction method for rapid underwater repair of the leakage cracks of the concrete faced rockfill dam has the advantages of simple materials, rapid construction, and capability of meeting rapid construction requirements during underwater emergency treatment. The invention further discloses a rapid underwater repair structure for the leakage cracks.
本发明公开了一种面板堆石坝渗漏裂缝水下快速修复施工方法。它由如下依次执行的步骤组成，步骤一：沿裂缝自上而下进行冲洗，确保混凝土基面冲洗干净；步骤二：再次冲洗混凝土基面；步骤三：水下环氧粘接底涂沿裂缝自上而下均匀涂刷；步骤四：水下快速密封材料搓成圆柱状，装袋送入水下；步骤五：将圆柱状水下快速密封材料沿裂缝按压密实，按压后保证中间厚两侧薄；步骤六：表面柔性防护层在水下沿裂缝摊铺后，采用固定结构将表面柔性防护层固定在混凝土基面上；步骤七：所有工序完成后，对处理区域进行检查。本发明具有材料简单、施工快速，满足水下应急处理时的快速施工需求的优点。本发明还公开了渗漏裂缝水下快速修复结构。
