FIELD: drainage amelioration. SUBSTANCE: invention is meant for drainage of country cottage plots and basements of country houses and other buildings. Process includes ditch digging with preset slope, leveling of bottom on which pipes which joints are covered with filtering material are laid, filling of ditches with ground and successive construction of inspection chambers and mouths on closed collectors. Additional internal drainage is arranged in basement of building. For it parallel slits and one perpendicular slit are cut in concrete plate of foundation of building to the depth of plate. Perforated pipes and disiccator pipes wrapped in glass cloth are placed in lower parts of parallel slits. Collecting pipe is laid in perpendicular slit and is linked to disiccator pipes. Lower parts of slit walls are covered with hydraulic insulation bitumen material and are filled with sand and gravel mixture, layer of hydraulic insulation material is laid above it and the rest parts of slits are sealed with concrete mortar. Collector pipe is bought outside of limits of foundation of building and is connected to pipe of circular drainage. Systematic drainage is arranged on country cottage plot which is linked to collector and the latter is connected through inspection chamber to string of circular drainage. EFFECT: intensified draining effect of drainage system by way fast discharge of water in emergency and hidden leaks in water-supply and sewerage nets. 2 dwg
