Description of the Related Art Conventionally, submersible pumps (vertical self-contained pumps) and horizontal self-contained pumps have been installed in boring holes and used for collecting and sending groundwater. In addition, when the above-mentioned pump cannot be installed with a small bore hole, a vacuum is generated by an air lift or an ejector to continuously pump up groundwater.

解決はならない。However, when the size of the submersible pump is larger than the diameter of the hole of the boring and the submersible pump cannot be installed, or when the suction pipe diameter of the self-contained pump is small, the suction pipe resistance of the groundwater is increased. It becomes larger and the pumping capacity is smaller than the pump capacity. In extreme cases, suction resistance makes pumping impossible. In such a case, it is possible to use an air lift or an ejector, but it is not possible to install a pipe for sending air and a pipe for pumping water, and it is not possible to use an air lift. Then there is no realistic solution.
