摘要

PROBLEM TO BE SOLVED: To avoid a double trap while accumulating floating substance such as fat and oil flowing into an inlet body, and fixing an elbow on the lower reaches so that the floating substance does not flow down to a sewer in a method of easily avoiding the double trap in the case of being generated before or after the fact in a trap inlet using a 90° elbow. ;SOLUTION: In the case of laying a trap inlet 1 with a vertical part 26 of a synthetic resin 90° elbow 2 as a water sealing part, when the formation of a double trap is proved after the fact, the elbow 2 is taken out, and a bottomed cylinder body 11 of small diameter provided at a horizontal part 9 of the elbow 2 is cut to dissolve the trap function of the elbow 2, thus avoiding the double trap easily. Since the elbow 2 is used as it is, flowing substance such as fat and oil can be collected without flowing to a sewer.;COPYRIGHT: (C)2000,JPO
