WATER-DRAINAGE STRUCTURE IN PLANT-CULTURING FACILITY

摘要

PROBLEM TO BE SOLVED: To provide a water-drainage structure in a plant-culturing facility, capable of connecting a water-drainage hose with a water-drainage main pipe simply and surely, and no disengaging them inadvertently even on getting an outside force to the water-drainage hose connected with the water-drainage main pipe. SOLUTION: This plant-culturing facility 1 is to water the cultured plant by supplying water to a culturing bed 2. A water-drainage main pipe 7 bored with an inserting hole 11 is arranged under the culturing bed 2. The lower end of a water-drainage hose 9 hanged by connecting its upper end with the culturing bed 2, is connected by inserting it into the inserting hole 11. The inserting hole 11 is formed as inclined toward the thicker direction of the pipe wall. The water-drainage main pipe 7 is installed at the installation surface 10 of the culturing bed 2 or buried below the installation surface. The insertion hole 11 opens up as inclined toward the installation surface 10 and facing to the inside of the culturing bed 2.
