ENERGY-EFFICIENT DEVICE TO RECYCLE RAIN AND MELTED DRAINS FROM ROOFS OF BUILDINGS IN URBANISED TERRITORIES

摘要

FIELD: construction.;SUBSTANCE: device comprises rain gutters (2), water intake funnels (3), drain pipes (4), a storm water outfall (7), filtering wells (16) and a subsurface accumulating reservoir (18). Drain pipes (4) are equipped with discharge parts with mini-hydroturbines (6). Power generated by mini-hydroturbines is sent to accumulator batteries. The storm water outfall is arranged below the level of the earth surface and is an extension of discharge parts of drain pipes. The filtering material is an ash and slag sorbent.;EFFECT: design will make it possible to prevent gradual damage of building basement and foundation elements due to availability of a subsurface storm water outfall.;4 cl, 2 dwg
