Old pipe cleaning method using rotatary water jet method combined with water pipe network diagnosis

摘要

The rotary water jet method of cleaning old pipes in which the water pipe network diagnosis is grafted according to the present invention includes a preparation step of selecting a working section of the water pipe to be cleaned; installing a saddle branch in a water supply pipe outside of the working section, which is upstream of a first drain valve installed in the uppermost stream of the water supply pipe in the working section; installing a working tool in the water supply pipe in the working section adjacent to the first diverting side toward the downstream side of the first watering side; Measuring the water quality of tap water and photographing the state inside the water supply pipe in the working section using CCTV; installing a washing pipe and a rotating waterjet device inside the water supply pipe in the working section through the working tool; connecting the washing pipe and the compressed air generator to a compressed air supply pipe; connecting the saddle branch and the washing pipe to a water pipe; installing a drain port in the water supply pipe in the working section adjacent to the second distillation side toward the upstream side of a second distillation side installed at the most downstream of the water supply pipe in the working section; Tap water flowing into the washing pipe through the water pipe is mixed with the high-pressure compressed air supplied from the compressed air generating device and moves to the rotary waterjet device, and then is rotated and sprayed at high pressure by a rotary nozzle to the inside of the water supply pipe washing the; Determining whether the internal cleaning of the water supply pipe is completed by photographing the condition of the inside of the water supply pipe in the working section using CCTV and measuring the water quality; and when it is determined that the internal cleaning of the water supply pipe is complete, restoring the working section.
