The present invention relates to a method for cleaning a water supply pipe. More specifically, washing areas are set up step by step for washing the water supply pipe buried in basements of a building, a shopping mall, a main house, an officetel, and so on, thereby reducing a cleaning time of the water supply pipe. A high pressure air of an air wave apparatus is continuously sprayed at 0.3 second intervals inside the water supply pipe, and cleaning work efficiency is improved by an action of a shock wave delivered to a washing water and a compressed air which cleans the water supply pipe. At the same time, in order to prevent a flow rate from being lowered due to flow friction during cleaning operations, an accelerated air supplied from an air accelerator is supplied through a branch pipe, so that a cleaning operation can be performed quickly without being limited by a cleaning operation length. The method for cleaning the water supply pipe of the present invention comprises: a setting step; a control step; a first washing step; a second washing step; and a finishing step. 본 발명은 상수도 도수관 세척공법에 관한 것이며, 더욱 상세히는 빌딩, 상가, 주책, 오피스텔 등의 건축물 지하에 매설된 도수관을 세척하기 위해서 세척 구역을 단계별로 설정하여 도수관의 세척 작업시간을 단축하고, 도수관의 내부에 공기파장장치의 고압공기를 0.3초 간격으로 연속으로 분사시켜 도수관을 세척하는 압축공기와 세척수에 전달되는 충격파 작용으로 세척 작업능률을 향상시키는 동시에 세척 작업시 유속 마찰로인한 유속 저하를 방지하기 위해 공기가속장치에서 공급되는 가속공기를 지관을 통해서 공급하여 세척 작업길이 제한을 받지 않고 신속하게 세척작업을 진행할 수 있는 상수도 도수관 세척공법에 관한 것이다.
