(57) Abstract Objective Without processing the tank specially, the upper tank in fixed water levelWhile containment, in the lower part tank the overflow water natural falling guttationOffer the drainpipe unit which it is possible. Constitution At the position where it is higher than intake A and the said intake A on1st bend B and the said 1st bend B which buckle in directionThe 2nd bend C which at the position where also the ri is low buckles in the downward look and beforeBeing the upward tube part D which leads to description 2nd bend C,Bend B of 1 compared to in the position where than low and it is higher intake APutting, to form drainage of ponded water section D1, at the same time the upper approaching of the said drainage of ponded water section D1So providing the opening D2 which, leads to the atmosphere the thing and the aforementioned tube which becomeGuttation the water which falls from the aforementioned drainage of ponded water section D1 of section D to the lower partThe drainpipe unit which possesses with the guttation section E which forms the aisle1. With this drainpipe unit 1 the water of 1st tank 2Over it tries to overflow to the tank 3 of 2Tank system of flow percolation mode.
