Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method for cleaning gray water pipes, and more particularly to a method for cleaning water pipes in apartments, housing complexes, buildings, etc.

PRIOR ART Currently, various methods such as water jet method and snake wire method are being used for cleaning water pipes in apartments, buildings, etc., but each method has various problems. For example, in the water jet method, cleaning water is forced into the outlet of the main gray water pipe, i.e., the water is forced in from the opposite direction to the flow of normal gray water.
In that case, cleaning water may flow from the gray water suction port of each household (customer's premises), polluting the customer's premises, emitting an odor, or causing a water leakage accident. There were problems such as the need for curing. Furthermore, in the snake wire method, a wire is passed through the gray water pipe, and the wire is used to move a cleaning device, such as a cutting device that removes water dust, etc. attached to the inner wall surface of the gray water pipe.
This method is difficult to construct, requires a large number of workers, and requires the workers to stay at the customer's site for a long time, causing trouble to the customer.

In view of the above-mentioned circumstances, the present applicant has previously proposed a gray water pipe cleaning method that is easy to install, takes a short construction time, and does not require curing at the customer's site.

FIG. 3 is a block diagram for explaining an example of the miscellaneous water pipe cleaning method previously proposed by the applicant.
1 is a power probe vehicle equipped with a suction pump device, 2 is a gray water capture and collection tank, 3 is a gray water outlet connection attachment, 4 is a vacuum hose, 5 is a plate rubber gasket, 6 is a gray water pipe branch pipe, and 7 is the gray water pipe main Pipe, 10 is the building where the gray water pipe cleaning work is being carried out, 11 to 13 are gray water suction ports installed on the first floor, 21 to 23 are gray water suction ports located on the second floor, 31 〜33 is the gray water suction port installed on the third floor, 41 to 43 is the gray water suction port installed on the fourth floor, R is the gray water suction port installed on the roof,
In the case of the figure, only the gray water suction port R installed on the roof is opened, and the others are, for example, plate rubber gasket 5.
is blocked by. Therefore, when the suction pump device is operated in this state, the outside air is drawn to the gray water suction port R on the roof, the gray water pipe branch pipe 6a, and the gray water pipe main pipe 7.
At the same time, water and dust adhering to the inner walls of the gray water pipe branch pipe 6a and the gray water main pipe 7, etc. are sucked out and captured in the gray water capture and recovery tank 2 and collected. be done. After cleaning the gray water passageway of the gray water suction port R on the rooftop in this way, this time, after blocking the gray water suction port R on the rooftop with the plate rubber gasket 5, the gray water suction port on the fourth floor, for example, is cleaned. When the rubber plate of the port 41 is removed and the gray water suction port 41 is opened, outside air flows from the gray water suction port 41 in the direction of arrow _A1 , and the gray water pipe is cleaned in the same manner as described above. Thereafter, the gray water suction ports that are opened are changed in the same way, and all the gray water suction ports are cleaned in the same way.

The water jet cleaning method removes dirt by spraying high-pressure washing water directly from inside the piping, so it can remove dirt well, but on the other hand, it only removes dirt well. The pipes become clogged due to scale, rust, foreign objects, etc. that have fallen into the pipes. Furthermore, since high-pressure washing water is used, there are drawbacks such as the washing water overflowing from the gray water inlet and causing a water leakage accident, as mentioned above. On the other hand, the above-mentioned suction cleaning method suctions and removes the filth in the gray water pipes, so the scale, rust, foreign matter, etc. that are peeled off and removed are suctioned at the same time as they are peeled off, so the fallen filth is removed. Although it does not clog gray water pipes and does not cause any problems such as bad odors or water leakage due to high-pressure water, it is not possible to thoroughly clean the entire inside of the pipes, especially in horizontal pipes. However, there was a drawback that it was not possible to completely remove dirt from the upper surface where there was no flow during suction cleaning.

Purpose The present invention was made in view of the above-mentioned circumstances, and in particular, it is an object of the present invention to effectively combine the water jet cleaning method and the suction cleaning method to take advantage of the advantages of the two cleaning methods and compensate for each other's shortcomings. This was developed with the aim of providing a pipe cleaning method that allows for

Configuration Figure 1 is a configuration diagram for explaining one embodiment of the present invention, and in the figure, parts that have the same effect as in Figure 3 are given the same reference numbers as in Figure 3. These are subjected to suction cleaning as described in connection with FIG. Therefore, the present invention effectively combines the above-mentioned suction cleaning method with a high-pressure jet cleaning method for cleaning.
50 is a high pressure washing vehicle, 51 is a high pressure washing hose, 52
2 is a high-pressure cleaning nozzle head, and the high-pressure cleaning nozzle head 52 injects water jet in the opposite direction to the flow of gray water and rotates by utilizing the reaction at the time of jetting, as shown in FIG. Therefore,
By inserting this high-pressure cleaning nozzle head into a gray water pipe and moving the nozzle head along the pipe while jetting water jet from the nozzle, it is possible to almost completely peel off the dirt in the pipe and remove it. The collected filth is effectively collected into the gray water capture and recovery tank 2 by the pushing force of the high-pressure washing water and the suction force of the suction pump, ie, without clogging the inside of the piping. Although the above example shows the case where the suction pump device and the water jet injection device are mounted on separate vehicles, it is also possible to install both devices on one vehicle. It is not necessary to drive the water jet and the water jet at the same time, but if the water jet injection device is driven while the suction device is running, in other words, if the water jet injection device is not operated alone, odors and cleaning water can be reduced. Cleaning work can be carried out without any problems such as gushing.

Effects As is clear from the above explanation, according to the present invention, the entire inside of the piping can be completely cleaned.
Furthermore, during the cleaning process, the interior of the pipes will not be clogged with dirt that has fallen off from the inner wall of the pipe to be cleaned, and there is no need to worry about bad odors or water leakage due to high-pressure water. can be provided. In addition, although an example in which the present invention is applied to cleaning gray water pipes has been described above, the present invention can be applied not only to cleaning gray water pipes but also to cleaning regular water pipes. can be easily understood.
