As described above, in this water supply pipe cleaning management method, the air hammer phenomenon is produced by passing a mixture of gas and water from the air hammer generator 7 through the water supply pipe 2 with high-speed water flow, and this air hammer This phenomenon is used to peel off and remove foreign substances such as rust, toughness and slime that have formed or adhered to the inner wall of the water supply pipe 2, so the energy for peeling off and removing foreign substances is hardly attenuated and the water is completely removed from the main pipe. Even in the water supply pipe 2 having a large diameter (150 mm in this embodiment), the water can be transmitted to every corner of the water supply pipe 2, so that it can be cleaned evenly. In addition, after the foreign matter is peeled off and removed, water is passed through the water supply pipe 2 at high speed, and the ozone-containing gas is effectively dissolved in the water and supplied for a predetermined period of time by utilizing the high speed of this water flow. Ozone, an ozone-containing gas that effectively dissolves in this water flow, forcibly and strongly oxidizes the inner wall of the water supply pipe, resulting in the formation of what can be called a protective oxide film, suppressing the subsequent formation of foreign matter. This is what will be done. In addition, an integrated pumping and precipitation pipe 2t is formed in the bypass path 6, and this integrated pumping and precipitation pipe 2L
By connecting an air hammer generator 7 and an ozone supply device 8 to the bypass path 6, the discharge power of the existing high-capacity pump 4 can be used for processing the mixture and ozone-containing gas. Since it is used to obtain the high-speed water flow required for these treatments, work efficiency is improved, especially since there is no need to install and remove separate "pumps" each time. As a result, the water supply pipe 2 can be cleaned and managed more frequently.
