A waterproof structure of an underground corrugated pipe is provided to rigidly fix a connected portion of an underground piping and the corrugated pipe using separate fixing tool. A semi-cylindrical body has a receiving part(32) receiving a connected portion of a piping and a corrugated pipe, and a packing assembled part(34) with an airtight packing(33). Upper and lower flanges(30a,30b) are assembled by a bolt(37) and a nut(38) which penetrate a hole(36) of a fixing part(35). The upper flange has an adhesive inlet port(40) and a rubber cap(45) engaged to the adhesive inlet port. The lower flange has a valve(60) and a resilient member(63). Grooves(39) are formed on both fixing parts of the upper and lower flanges. |
