    Abstract: PROBLEM TO BE SOLVED: To correctly and easily bore an ejection hole of a tube on a discharge part of a pressure reducing drip regardless of change of interval between pressure reducing drips, in a water pipe. SOLUTION: As the water pipe boring method consists of a first step for forming an upward projection to be higher than the drip at the discharge part of the pressure reducing drip, a second step for forming a protruding part on a drip pressure reducing hose by the upward projection of the drip when the drip is adhered to inside of the drip pressure reducing hose and a third step for forming the ejection hole of the drip pressure reducing hose by horizontally cutting an upper part of the protruding part formed on the drip pressure reducing hose by the second step, the ejection hole of the drip pressure reducing hose can be bored correctly on the discharge part of the pressure reducing drip more easily without difficulty and labor of operations to correctly set the interval of the pressure reducing drips and to correctly match a delivering speed of the drip pressure reducing hose and a rotating speed of a punch wheel.
