ら水垢等を取り除く方法も行われていた。Background Art Pipes (water supply pipes, etc.) for supplying tap water or miscellaneous water for drinking or other purposes are installed in general buildings, apartment houses, and the like. Such tubes include cast iron tubes, galvanized steel tubes, lead tubes, copper tubes, asbestos cement tubes, and hard vinyl chloride tubes. Since these pipes become unsanitary due to water stains, scales, rust, etc. on the inner wall surface after long-term use, it has been conventionally practiced to wash the inside of the pipes by pouring a cleaning liquid from a water spigot such as a building. A method has been adopted in which high-pressure water compressed by the method is driven into a pipe and the water pressure removes scales and the like adhering to the inside of the pipe. In addition, a method has also been performed in which a wire having a brush attached to the tip is inserted into a tube and the scale is rubbed against the inner wall surface of the tube to remove water stains.

業工程を要するという難点もあった。However, if the inside of the tube is cleaned using a cleaning solution,
Not only water stains, scales, rust, etc. cannot be completely removed, but there is also a problem that drinking water cannot be used for several days due to residual cleaning liquid. In addition, it is difficult to completely remove water stains and the like adhering to the inside of pipes even with water pressure washing using high-pressure water. Furthermore, since large-scale equipment such as compressors and water tanks are required, a lot of work is required before washing. There was also a drawback that it required a process.

る。On the other hand, households, factories, agricultural areas, etc. have wells for drinking water and agricultural water. Wells usually contain well pipes such as earth pipes and fume pipes in order to prevent landslides in the dug holes. A general well pipe is composed of a tubular casing portion and a screen portion having a plurality of small holes, and groundwater permeating through the screen portion and accumulated inside the well pipe is pumped up by a pump as needed.

部に排出される。As in the case of pipes in houses and buildings mentioned above, since water stains, scale, rust, etc. will adhere to the inner wall of such well pipes over a long period of time, it is necessary to regularly clean the well pipes from the viewpoint of hygiene. Need to be washed. As a general cleaning method, as shown in FIG. 9, a wire brush 140 larger than the inner diameter of the well tube 102 is moved up and down to remove scales and the like adhering to the inner walls of the casing 103 and the screen 104. Can be mentioned. The water stains, sediments, etc. in the well pipe 102 removed by such work are sent to the well pipe 102 with high pressure air by a compressor 141 as shown in FIG. Is discharged to.

必要となり、洗浄コストも高額となっていた。However, the conventional method for cleaning the inside of the well pipe is divided into the work of removing the scales from the inner wall and the work of discharging the scales from the well, which requires a lot of working time and labor, and also the cleaning cost. It was expensive.

Furthermore, in the method of raising the air and discharging scales and sediments, for large scales and heavy sediments,
It was impossible to discharge it out of the well pipe.

除去することができる。Further, at the same time as the compressed air b is discharged from the hose 111, high-pressure water c of about 100 to 200 m / s is sent to the high-pressure hose 121 from the high-pressure water production machine 120, and obliquely upward from the discharge port 123 of the cleaning nozzle 122. It is jetted vigorously. Therefore, due to the expansion of the compressed air b, the high pressure water c is directly blown to the wall surface of the well pipe 102 through the large bubble portion d formed in the well pipe 102, and the well pipe 10
It is possible to remove water stains, rust, etc. adhering to the inside 2 more reliably and efficiently.

去することができる。Further, it is preferable to operate the carbon dioxide gas supply device 122 and drive the carbon dioxide gas into the pipe from the tip of the hose 111 according to the degree of contamination of the well pipe 102. The carbon dioxide gas sent from the carbon dioxide gas supply device 112 is intermittently or continuously injected into the well water w by the disperser 110 at appropriate intervals and is dissolved in the well water w, and then the well pipe 102.
It evaporates as it rises in the well, and due to its foaming action, the well tube 1
It is possible to strongly remove scales, scales, rust, etc. attached to the inner wall of 02.

The inner wall surface of the pipe can be cleaned, and at the same time, the water leak of the pipe can be investigated. Further, according to the well pipe cleaning method and apparatus of the present invention, compressed air, particularly carbon dioxide gas, can be used. With the synergistic effect of the high pressure water and the high pressure water, it is possible to easily and efficiently clean the inside of the well pipe in a short time by reducing working time and steps.
