共に，機場規模が大となり，工事費が嵩むという問題点
がある。In the above conventional pump equipment 4, an indoor pump or a submersible pump is mainly used. Of these, submersible pumps are used for relatively small-scale pump equipment, but the pumps themselves are expensive and have a short service life.
Due to the complexity of maintenance, indoor pumps are relatively widely used. However, in the case of the indoor pump, there is no particular problem when the river is at the normal water level W 1 , but when the water level increases to the water level W 2 during heavy rain, the pump facility 4 may be submerged or submerged. Therefore, in order to avoid these unforeseen circumstances, for example, the station 2 should be constructed with waterproof reinforced concrete and the river should be at the water level.
In the case of swollen to W 2 also, the pump facility 4 is prevented from flooding or submergence is generally. For this reason, it is extremely difficult to select the installation location of the pump equipment 4, and the size of the machine site becomes large, resulting in an increase in construction costs.
