FIELD: construction.
SUBSTANCE: invention relates to construction, specifically to methods for cleaning pipes and risers of sewage network of settlements and industrial enterprises. Technical result is achieved using a method, which comprises formation of self-destructing piston and its movement. On clogged section of pipeline of network in inspection sewage pit on inlet side of waste water in pipeline are arranged guide tubular overpass total height above it of not less than twice depth of well and its lower end of yielding part overpass, for example, in form of bellows is inserted into pipeline. Then in outer edge of non-deformable part smooth-pipe overpass or riser is fit a pre-formed self-destructible piston comparable on diameter, and is provided, due to forces of gravity, with accelerated motion in system overhead crossing pipeline or standpipe and opposite collision with clogging in pipeline or riser up to its removal.
EFFECT: technical result consists in reduced operating costs for maintenance of sewage network.
