<p>A sprinkling system for sprinkling water flowing through piping from sprinkling parts (30) provided on the outer circumferential surface of the piping around the piping. The piping is formed by coupling a first water supply pipe (10) and a second water supply pipe (20) alternately and removably. The first water supply pipe (10) has an outside diameter, at the opposite ends thereof, equal to the inside diameter of the second water supply pipe (20). The first water supply pipe (10) is provided, on the outer circumferential surface at one end part thereof, with a plurality of first meshing protrusions (11) at positions rotationally symmetric with respect to the center line of the first water supply pipe (10). The second water supply pipe (20) is provided, at one end thereof, with a plurality of second meshing protrusions (21) meshing the plurality of first meshing protrusions (11) of the first water supply pipe (10) when the end part of the first water supply pipe (10) is inserted into the second water supply pipe (20).</p> |
