A multi-pipe drainage element punching unit and a punching method are provided to reduce the cost of drilling/punching process and the working time by using a plurality of drilling/punching units are rotated at high speed. A multi-pipe drainage element punching unit comprises the respective first and second guide plates(20,20') guided up and down circumference side of synthetic resin conduits(1,2) incleded each layer of the multi-pipe drainage element laminated to the cephalic slit,; the first which is combined in the worktable(D) to be separated from guide plates and be at right angle to the longitudinal direction of synthetic resin conduits, and second axis of rotations; the punch stations(10,10') consisting of first, and a plurality of rotation boards(12,12'). As to a plurality of rotation boards, perforators(13,13') are fixed to the outer circumference while being fixed to the outer circumference of second axis of rotations(11,11') to equally-spaced; the driving part rotating the first, and second axis of rotations; and the controller controlling the punch stations and driving part. |
