THE NEEDLE OF THE BUILDING NAP INTERCEPTION DRAINAGE SYSTEM IT WILL DANCE

摘要

A draining apparatus for blocking sewage infiltrating into building is provided to prevent a lower story from being contaminated and to prevent a bad smell from being generated in advance by draining the leaching sewage to a main pipe before the leaching sewage leaked at an upper story is leaked to the lower story. A draining apparatus for blocking sewage(w') infiltrating into building includes a leaching sewage blocking unit(10), a sewage passing pipe unit(20), and a leaching sewage drain pipe unit(30). The leaching sewage blocking unit has an upper horizontal edge unit for fixing a sewage pipe which penetrates a bottom plane of a concrete partition layer(3) of the building. The leaching sewage blocking unit has a side unit(13) and a bottom water collecting surface unit(14) to form a leaked water receiving groove which receives the leaching sewage leaked from the concrete partition layer. The sewage passing pipe unit passes sewage(w) therethrough by connecting the sewage pipe and a drain pipe to an upper standing pipe unit and a lower standing pipe unit(22) which are vertically formed from the bottom water collection surface unit respectively. The leaching sewage drain pipe unit of an L-shape is installed to be connected to the bottom water collecting surface unit and the lower standing pipe unit so that the leaching sewage introduced into an inlet hole(31) formed on the bottom water collecting surface unit is drained to an outlet hole(32) of the lower standing pipe unit.
