理施設まで運搬するようにしている。Currently, the most popular method for cleaning sewer pipes and the like is to dispatch a high-pressure washing vehicle equipped with a high-pressure water generator that generates high-pressure water and a water truck that supplies washing water to the high-pressure washing vehicle to the work site. Then, the high-pressure water generated by the high-pressure water generator is supplied to a special nozzle via a high-pressure hose, and the high-pressure water is jetted from this special nozzle to peel off sludge and the like deposited in the sewer pipe by the high-pressure jet water. Stir,
In addition, the special nozzle itself is propelled in the sewer pipe by using the jet reaction force to automatically clean the inside of the sewer pipe, and further, while the high-pressure water is jetted, the nozzle is reversed in the opposite direction. By pulling back in the direction, the sludge that has been separated and agitated is accumulated in the pit directly below the manhole, and the sludge accumulated with another sludge tank and a sludge suction truck equipped with a sludge pump is pumped together with the wastewater to the sludge tank for sludge treatment. I try to transport it to the facility.

のである。First, when the vacuum pump of the vacuum pump device (3) is driven, the air in the sludge water chamber (9) of the storage tank (2) is sucked into the vacuum pump, and the inside of the sludge water chamber (9) is exhausted and decompressed. Then, when the sludge water chamber (9) is depressurized to a predetermined negative pressure, the suction hose led out from the sludge water chamber (9) is put into the cleaning target portion at the tip, and a cock provided in the middle of the suction hose. open. Then, the sludge water in the portion to be cleaned is sucked into the sludge water chamber (9) of the storage tank (2) through the suction hose. When the discharge cock (12) is opened and the first-stage pump (5) and the second-stage pump (6) are driven while continuing to suck in the sludge water in the area to be cleaned in this way, the sludge in the storage tank (2) is Only the sewage of the sludge water sucked into the water chamber (9) is pumped by the first-stage pump (5) through the pipe (10) to the sewage separator (4), where it is separated into purified water and solid matter. The purified water flows into the purified water chamber (8) of the storage tank (2) through the pipe (13) by the second-stage pump (6),
The solid matter is sucked into the sludge water chamber (9) by the negative pressure in the sludge water chamber (9) of the storage tank (2). The purified water stored in the purified water chamber (8) of the storage tank (2) in this way is supplied to the high-pressure washing vehicle as washing water and discharged to the portion to be cleaned. The above operation is repeated to pump up the sludge water in the portion to be cleaned into the sludge water chamber (9) of the storage tank (2).

ことは云うまでもない。Although the pumps (5) and (6) are provided on both the inlet side and the outlet side of the sewage separator (4) in the above embodiment, if the sewage is high-pressure water, the two-stage pump (6) ), It is also possible to use a part of the high-pressure water generated from the high-pressure washing car, or to separately mount a high-pressure pump to use an ejector-type pump. Further, in the above embodiment, the solid matter side outlet of the sewage separator (4) and the sludge water chamber (9) of the storage tank (2) are connected by the pipe (14), but the sewage separator (4) is connected. It may be provided in the upper part of the sludge water chamber (9) of the storage tank (2), and the solid matter may be dropped directly into the sludge water chamber (9). Further, it goes without saying that it is naturally used only for pumping sludge water.
