Circular resource recovery pipe so that the capacity of water for moving the water surface in the circular resource recovery pipe to a position above the water surface outside the circular resource recovery pipe is relatively larger than the capacity of water discharged from the water discharge opening. If the inner shape of the upper part is made, air will not be inserted from the water discharge opening. Even if air is inserted, the circular internal penetrating member has a central opening. Therefore, when the internal penetrating member is moved to the upper part of the circular resource recovery pipe, the sea surface or the lake surface in the circular resource recovery pipe Alternatively, it is possible to suck air inserted from the water discharge opening through the river surface and the lower surface of the internal penetrating member through the central opening.
