2. Description of the Related Art Conventionally, for example, in a place where a tributary flows into a river (main stream), a gate for opening and closing the tributary is installed on the tributary side. When the river rises due to heavy rain or the like, closing the gate prevents the water of the river from flowing back to the tributary. On the other hand, the water flowing from the upstream of the tributary when the gate is closed is forcibly drained to the river by the pump.

In order to save space, some of these types of gates include a pump gate having a structure in which the drain pump is externally attached to the gate itself and a gate built-in structure in which a pump is installed inside a door body. There is a pump gate, which has been used.

The shape and size of this type of gate and the required number of pumps vary greatly depending on the shape of a water channel such as a river to be installed and the amount of flowing water. However, conventional pump gates have a structure that incorporates the necessary number of pumps into one gate manufactured according to the shape of the water channel such as a river to be installed, so it is designed with a different shape and structure for each water channel to be installed. Must be manufactured and its design and
Manufacturing and factory performance testing of the pump were complicated.

A conventional gate or pump gate is provided with a skin plate for always shutting off the water channel on the water stop side. However, if the area of the skin plate is large, the overall manufacturing cost is high.
