圧送される。 In the above configuration, when cleaning the inside of the concrete transport pipe 1, the on-off valves 11, 13, and 18 are closed, and the on-off valve 10 is opened. When the water pump 5 is operated by operating the on-off valve in this manner, water in the water tank 6 flows into the concrete transport pipe 1 via the water pump 5, the on-off valve 10, and the hose 9. After cleaning the concrete transport pipe 1, the on-off valve 10 is closed, the on-off valves 11, 13, and 18 are opened, the boom (see Fig. 1) is raised, and the car washing operation begins. In this case, since the on-off valve 10 is closed, the water discharged from the water pump 5 flows into the hose 16 and the excess flow return pipe 14. The water flowing into the excess flow return pipe 14 flows into the water tank 6 via the water injection pump 12, and the water injection pump 12 starts operating. Concrete transport pipe 1
The water inside is drained to the hose 9, the on-off valve 11, and the water injection pump 1 by the suction force of the water injection pump 12 and the natural fall phenomenon caused by gravity when the boom is erected.
2 and is collected in a water tank 6. The water collected in the water tank is pumped to the hose 16 by the water pump 5.
以上において水ポンプ５はコンクリート輸送管
