Accordingly, when the cleaning operation of the water supply pipe 100 is completed, the second water regulating valve 65 is shut off to prevent tap water from flowing out through the second sperm pipe 60.

  • the rotational waterjet method of cleaning old pipes incorporating the diagnosis of the water pipe network unlike the prior art, it rotates at high pressure through a rotating nozzle without using a scraper that scrapes the inner surface of the water pipe. Since foreign matter such as scale adhered to the inner surface of the water supply pipe can be removed by the sprayed tap water and compressed air, there is an advantage in that it is possible to efficiently clean the water pipe while minimizing damage to the inner surface of the water pipe.
  • tap water is not supplied to the rotary water jet device through the already installed water valve, but branched from the saddle branch installed upstream of the water valve. Since the inner surface of the water supply pipe is cleaned by supplying tap water to the rotary water jet device, there is an advantage in that it is possible to prevent dripping water from occurring in front of the water valve.

Abstract

L'objectif de la présente invention est de fournir un procédé de lavage de tuyau porté de type jet d'eau rotatif combiné à un diagnostic de réseau de tuyau d'eau, procédé dans lequel : un réseau de tuyau d'eau est diagnostiqué ; et de l'eau de robinet et de l'air comprimé à haute pression sont injectés au moyen d'un appareil à jet d'eau rotatif pour éliminer le tartre formé sur la surface interne d'un tuyau d'alimentation en eau souterraine, ce qui permet d'augmenter l'efficacité d'élimination de tartre tout en réduisant au minimum les dommages faits à la surface interne du tuyau d'alimentation en eau souterraine.
