Method for repairing dam crack defect by using magnetic mortar
A method for repairing dam crack defects by using magnetic mortar comprises the following steps: Step 1, detecting concrete dam cracks by using ultrasonic waves, and determining the specific position, size and trend of the cracks needing to be repaired; 2, a construction working face is cleaned and repaired, and precipitates on the concrete surface of the dam are chiseled away; 3, the number, the position, the depth, the diameter and the distance of grouting holes are determined according to the specific position, the size and the trend of the crack, and the grouting holes are drilled through a drilling machine; 4, a grouting nozzle is embedded in the drilled grouting hole, a grouting pipe is inserted, a power source is arranged outside the working face, and a movable electromagnet with the magnetic force capable of being adjusted and controlled is placed; 5, the magnetic mortar is placed in a grouting machine, and the grouting machine is used for sequentially injecting the magnetic mortar into grouting nozzles through grouting pipes; the crack repairing method is used for solving the problem that in an existing crack repairing method, the mortar filling rate in a crack can not be well increased possibly due to water flow or gravity and the like.
一种利用磁性砂浆修补大坝裂缝缺陷的方法，包括如下步骤：Step1：使用超声波对混凝土大坝裂缝进行检测，确定需要修补的裂缝的具体位置、大小和走向；Step2：清理修补施工工作面，凿除大坝混凝土表面析出物；Step3：依据裂缝的具体位置、大小和走向，确定好注浆孔的数目、位置、深度、直径和间距，使用钻机钻取注浆孔；Step4：在钻好的注浆孔上埋置注浆嘴，并插入注浆管，并在工作面外安置好电源，放置可调控磁力大小的移动式电磁铁；Step5：将磁性砂浆置入注浆机中，使用注浆机将磁性砂浆通过注浆管依次注入注浆嘴中；本发明用于解决现有裂缝修补方法中砂浆可能会因为水流或者重力等原因并不能够很好地增大裂缝中的砂浆填充率的问题。
