REPAIRING AND REINFORCING PROCESSING METHOD OF WATER SUPPLY PIPE

摘要

A water supply pipe repairing and reinforcing method is provided to exactly remove the rust, to secure uniform lining coating, and to repress corrosion of a pipe by using an electrode wire. The water supply pipe repairing and reinforcing method comprises the steps of: firstly drying a water supply pipe(100); removing the rust of an inner wall of the water supply pipe by supplying silica sand(111) to a high-pressure air spiral flow; washing the rust removed from the inner wall of the water supply pipe by supplying high-pressure water to the high-pressure air spiral flow; secondly drying the water supply pipe; diagnosing the thickness and texture of the wall of the water supply pipe; and lining the inner wall of the water supply pipe by supplying the lining paints to the high-pressure air spiral flow.
