PIPE FOR DISCHARGING IN-PIPE FOREIGN MATTER

PURPOSE:To efficiently discharge foreign matter flowing inside a pipe to the outside of the pipe. CONSTITUTION:A discharging pipe comprises a horizontal main pipe 6, an inflating portion 9 formed at the end of the main pipe 6 and branching in the direction other than that of the main pipe 6, and an inner pipe 13 connected to the main pipe 6 at the opening 8 of the main pipe 6 on the side of the inflating portion 9 and fitted into the main pipe 6 from the opening 8 of the inflating portion 9. An opening 19 for communicating the inside of the inner pipe 13 with the inside of the inflating portion 9 is formed at least through the bottom of the inner pipe 13. Therefore, foreign matter 20 can be accumulated in the inflating portion 9 and be efficiently discharged to the outside of the pipe through the branch pipe 11. The discharging pipe can be obtained simply by insertion of the inner pipe 13 into the math pipe 6 and is therefore easy to manufacture.
