PROBLEM TO BE SOLVED: To provide a tube for sprinkling in which positions and sizes of sprinkling halls hardly change even when air temperature varies at a time of sunshine or the like and which hardly deteriorates even after long time use.SOLUTION: A tube 1 for sprinkling comprises, in a longitudinal direction, a plurality of sprinkling halls H are provided at intervals and a water pipe 10 which is laid on a ground surface G with a lower half part 10D thereof facing the ground surface G side and an upper half part 10U thereof facing upside. Thickness of the upper half part 10U is formed to be thicker than thickness of the lower half part 10D. It is preferable that the thickness of the upper half part 10U becomes gradually thicker toward an apex 13.COPYRIGHT: (C)2015,JPO&INPIT【課題】日照時等の気温変動が発生しても灌水孔の位置や大きさが変動し難く、長期間使用しても劣化し難い灌水用チューブを提供する。【解決手段】長手方向に間隔をおいて複数の灌水孔Hが設けられ、下半部10Dを地面G側に向け、上半部10Uを上方側に向けて地面Gに設置される送水管10を備えた灌水用チューブ1であって、上半部10Uの肉厚が下半部10Dの肉厚よりも厚く形成されている。上半部10Uの肉厚が頂部13に向けて漸次厚くなっていることが好ましい。【選択図】図2
