MANHOLE REPAIR METHOD USING CIRCULAR CUTTER ON ROAD, HAVING IMPROVED CUTTING DEPTH

摘要

The present invention relates to a manhole repair method using a circular cutter on a road, having improved cutting depth. The manhole repair method can prevent damage to an existing pavement layer, separation of the existing pavement layer, or resonance by forming the deep cutting depth of the road when a manhole is repaired. The manhole repair method using the circular cutter on the road comprises: a road cutting step using the circular cutter on the road, wherein the circular cutter includes a circular arc-shaped grinding wheel forming a curvature radius; a road excavating step; a steel opening lifting step; a base layer forming step; and a finishing layer forming step of forming a finishing layer using a finishing material comprising one selected among asphalt concrete or mortar. The manhole repair method using the circular cutter on the road can reduce the damage to an existing pavement surface, the separation, and vibration generation by forming the deep cutting depth by controlling the cutting depth on the road in a rotation method and the shape of the grinding wheel. The manhole repair method can be applied to manholes of various diameters. The manhole repair method can prevent degradation of a cutting force and can prevent damage to the inner circumference of a wheel body by changing the structure of the grinding tip of the grinding wheel. Also, the manhole repair method enables work on an overlay road.;COPYRIGHT KIPO 2019
