Repair method for water seepage crack of thin-wall concrete structure
The invention relates to the technical field of concrete construction, in particular to a repairing method for a water seepage crack of a thin-wall concrete structure. The method comprises the steps that 1, the position of a water seepage crack is determined, the position of the crack is marked, and the surface of the crack is cleaned; 2, a grouting groove is formed in the extending direction of the crack, the width of the grouting groove is larger than the maximum width of the crack, and a grouting nozzle and an exhaust nozzle are arranged on the grouting groove so that grouting materials can smoothly reach the interior of the crack through the grouting groove; 3, the grouting groove is blocked through a blocking material, and it is guaranteed that the peripheries of a grouting nozzle and an exhaust nozzle are blocked tightly; step 4, carrying out closed gas experiment detection; 5, a grouter conducts high-pressure grouting through a grouting nozzle; and 6, after grouting is finished, the plugging material is cleaned, the grouting nozzle and the exhaust nozzle are dismantled, and the base face of the repairing position is cleaned. The grouting groove is formed in the extending direction of the crack, it can be avoided that a grouting hole is drilled in a small-size thin-wall concrete structure, and the whole thin-wall concrete structure is prevented from being damaged.
本发明涉及混凝土施工技术领域，具体涉及一种薄壁混凝土结构渗水裂缝的修复方法。该方法包括：步骤1：确认渗水裂缝位置，对裂缝位置进行标记并对其表面进行清理；步骤2：沿裂缝延伸方向开设灌浆槽并且灌浆槽的宽度大于裂缝最大宽度，在灌浆槽上设置注浆嘴和排气嘴，以利用灌浆槽使灌浆料顺利到达裂缝内部；步骤3：利用封堵材料封堵灌浆槽，并保证注浆嘴和排气嘴周围封堵严实；步骤4：进行闭气实验检测；步骤5：灌浆机通过注浆嘴进行高压灌浆；步骤6：灌浆结束后清理封堵材料，拆除注浆嘴和排气嘴并清理修复位置的基面。通过沿裂缝延伸方向开设灌浆槽，能够避免在尺寸较小的薄壁混凝体结构上钻设灌浆孔，避免破坏薄壁混凝土整体结构。
