Method for repairing cracks of pavement and dam face by using magnetic mortar
The invention provides a method for repairing cracks of a road surface and a dam surface by using magnetic mortar, which comprises the following steps: drilling and preparing the magnetic mortar along the cracks of the road surface or slots obtained by slotting and expanding the cracks, and placing a neodymium iron boron strong magnet on a repairing device next to one side of the cracks, so that a magnetic field is generated in the cracks at the moment; the left-right flowing range of the magnetic mortar is limited, under the action of high-strength grouting pressure, the interior of the crack is repaired, and the filling rate of crack grout and the integrity of a road are improved. The method is easy and convenient to operate and short in consumed time, the capacity of resisting the vehicle load and the environmental factor influence of the asphalt concrete pavement can be greatly improved, the service life of the asphalt concrete pavement is prolonged, and the road maintenance cost is remarkably reduced.
本发明提供了一种利用磁性砂浆修补路面和坝面裂缝的方法，通过沿着路面裂缝或者开槽、扩缝得到的槽缝进行钻孔，配制磁性砂浆，再使修补装置上的钕铁硼强磁铁紧挨着裂缝的一侧放置，此时裂缝内部有磁场产生，磁性砂浆左右流动范围受到了限制，在高强注浆压力的作用下，对裂缝内部进行修复，提高裂缝浆液的填充率和道路整体性。上述方法，操作简便，耗时较短，还能够大幅度改善沥青混凝土路面抵抗车辆荷载和环境因素影响的能力，延长沥青混凝土路面的使用寿命，显著降低公路养护维修成本。
