    Abstract: A vertical shaft type pump including a bearing device in which water in the pump is utilized as lubricating water without supplying water to the bearing from the outside of the pump, thereby repeatedly conducting no-load operation in the air (in such a state that water is not pumped) stably for a long period of time. In the pump, a water storage tank upwardly opened is fixed to a rotary shaft, and the lubricating water (the water in the pump) is retained within the water storage tank so that the bearing is operated while being always soaked in the lubricating water. Also, foreign substances in the water storage tank are mixed with the water without deposition, and the water containing the foreign substances is replaced by the newly pumped water.

    Abstract: An underground water channel is provided in an underground of a large depth, and rain water and the like flow into this underground channel from flood control channels, conduits and rivers through vertical shafts. A pump well of a pump station is connected to a downstream end of the underground channel, and water flowing into the pump well is discharged by a pump to a discharge tank. The pump is disposed generally at a medium water level of the underground channel, and a lowest water level L.W.L enabling draining is the medium water level of the underground channel. In an open channel flow operation of an open channel-closed channel mixed flow operation, water level of the underground channel is maintained at the lowest water level L.W.L, so that the underground channel is in an open channel condition. In the closed channel flow operation, the underground channel is fully filled with water, and further water level rises into the vertical shafts, so that the underground channel is in a closed channel condition. By changing an outflow factor in accordance with rainfall patterns, the rate of flow into the vertical shafts can be accurately estimated, so that the large-depth underground drainage facility can be run in a stable manner.

    Abstract: A plural drainage pumps PH are disposed on the high floor gradation state at the circular shape. A plural drainage pumps PL are disposed on the low floor gradation state at the circular shape. The drainage pump PH disposed on the high floor gradation is installed at the high level. The drainage pump PH is set one having the low pump head and the large capacity in comparison with those of the drainage pump PL disposed on the low floor gradation. An outer shape of an underground pump construction building is formed a circular cone shape spreading toward an upper portion. The discharge water power can be reduced and the construction area for the underground pump construction building can be reduced and further the engineering working amount such as a digging working at the underground can be lessen.
