Description

[Detailed Description of the Invention] Limb 1B Length 1 The present invention is a method for cleaning gray water pipes, more specifically, a method for cleaning gray water pipes in mansiran, housing complexes, buildings, etc. Currently, gray water pipes in apartments, buildings, etc. For example, various construction methods such as water jet method and snake wire method have been implemented, 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, that is, from the opposite direction to the flow of normal gray water. Cleaning water may flow out of the gray water suction port at the customer's site, staining the customer's site, emitting odors, or causing shallow water accidents. There were problems such as. In addition, the snake wire type is a system in which 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 rings, etc. attached to the inner wall surface of the gray water pipe. This method is difficult to construct and requires a large number of workers.
In addition, there were problems such as the workers staying at the customer's site for a long time, causing inconvenience to the customer.

1.The present invention was made in view of the above-mentioned circumstances.
This was done with the aim of providing a new gray water pipe cleaning method that is easy to construct, takes a short construction time, and does not require curing on the part of the customer.

1 Figure 1 is a block diagram for explaining one embodiment of the present invention. In the figure, 1 is a power prober vehicle equipped with a suction pump device, and 2 is a gray water capture and recovery 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, 7 is a gray water pipe main pipe, 10 is a building where the gray water pipe cleaning work will be carried out, 11 to 13 are gray water suction ports located on the first floor.21 to 23 are gray water suction ports located on the second floor.
1-33 are gray water suction installed on the 3rd floor 0.41-43
is the gray water suction port installed on the 4th floor, and 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 open, and the others are , is closed by a plate rubber gasket 5. Therefore, when the suction pump device is driven in this state, outside air is sucked in the direction of arrow A through the gray water suction port R9 on the roof, the gray water pipe branch pipe 6a, the gray water pipe main pipe 7, etc., and at the same time, the gray water pipe branch tube 6a
Water rings and the like attached to the inner walls of the gray water main pipe 7 and the like are sucked out and captured and collected in the gray water capture and recovery tank 2.

After cleaning the gray water passageway of the gray water suction port R on the rooftop in this way, the gray water suction port R on the rooftop is blocked with the plate rubber gasket 5, and then, for example, the gray water on the fourth floor is cleaned. Remove the plate rubber gasket of the suction port 41 and remove the gray water suction port 41.
When 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. After that, we changed the gray water suction port that was opened in the same way,
Perform the same cleaning for all gray water suction ports. In addition,
The example above has been explained in which one gray water suction port is opened, but the number of gray water suction ports that are opened can be set to two or three depending on the capacity of the suction pump, the diameter of the gray water pipe, etc. You can. In addition, by introducing crushed ice or the like through the open gray water suction port, it is possible to more effectively remove water rings, filth, etc. attached to the inner wall surface of the gray water pipe. In addition, although the case where cleaning is carried out sequentially from the upper floor has been explained above, the construction order can be devised, for example, in the location shown in the illustration, first open the gray water suction port R on the roof and clean it as above. and
First, the main pipe 7 is cleaned with air to make the sludge-like waste flow, and the waste is removed by throwing crushed ice where it has settled.For example, when fresh water begins to flow into the collection tank, the main pipe After completing the cleaning, the branch pipe 6 is then cleaned, and crushed ice is introduced from the gray water suction port near the main pipe and the suction pump device, for example, from the suction port 12 in the illustrated example, and the following steps are carried out, e.g. , 11.13. on the 1st floor. 22. on the 2nd floor.
21, 23. 32 on the 3rd floor. 31. 33. 42.4 on the 4th floor.
1.43, and finally, add crushed ice again from R on the roof to complete the work.

As is clear from the above explanation, according to the present invention, there is no damage to existing drainage pipes, no back pressure injection from each drainage suction port, etc.
Further, there is no possibility of waste remaining in each branch pipe. Additionally, even if waste becomes clogged during construction, it can be flushed out by crushing ice.

Furthermore, during construction, you can simply install or remove the plate rubber backing and change the opening position of the drainage suction port.
It is very easy to install and requires little experience, and
It has the advantage of reducing work costs and requiring less cleaning time. In addition, compared to the conventional water jet system, there are advantages such as no water leakage, 2 customer sites are clean, 9 customer sites do not need curing, and 5 customer sites do not have odors.
