Abstract

PURPOSE: To form a strainer for a well witout generating noise by a method wherein a multiple water collecting slits are formed sumultaneously on a peripheral wall of an iron pipe.
CONSTITUTION: An iron pipe P is supported horizontally by V-shaped receiving blocks 3 in a bucket 1 and is fixed by fixing cylinders 33 through clampers 35. A plurality of revolving cutters 18 are moved up-and-down with respect to the pipe P by hydraulic cylinders 25 and slits B having predetermined lengthes are formed on the pipe by the revolving edges 18. The iron pipe P is moved to left and right by cylinders 4, 12 while pivoted to a position of the next slits by an operation of a handle 10. The bucket 1 is filled with cutting oil 2, therefore, generation of noise may be prevented.
