く等の欠点を有していたものである。Conventional technology In general, when the natural groundwater level in an in-rock water seal tank (oil storage tank) decreases and the water seal function cannot be maintained,
It is normal to install a water seal tunnel and water seal boring for underground water supply separately from the water seal tank and the piping tunnel connected by the delivery shaft.In this case, the water seal tunnel and water seal boring for water supply are constructed. However, this method has disadvantages such as an increase in the costs involved, making the overall cost high.

The technique is to lay gravel at the bottom of a pipe tunnel formed at the top of an underground cavern to form a permeable layer, form a concrete floor on top of the layer, and connect the concrete floor to the wall of the pipe tunnel. A water layer is formed along a part or the entire surface of the wall at the connecting part of the wall, but this makes it impossible to send pressurized water to the water-seal borehole and water-seal tunnel.
