TANK FOR ACCUMULATION AND STORAGE SURFACE, STORM AND TECHNICAL WATER AND ITS MANUFACTURING METHOD

摘要

FIELD: construction.;SUBSTANCE: tank includes feeding wells, water storage vessel, perforated pipes, filtering material. Water storage vessel is made in the form of tank pit (1) where bottom and side walls are covered with protective underlying bed (2) on which impermeable polymer membrane (3) is laid. Perforated drain pipes (4) are installed above the membrane and covered with a gravel layer (5). Modular structures (6) are made in the form of rainwater collectors and determine hard frame structure of the tank pit. Tank erection method involves construction of feeding wells, installation of perforated pipes (4), filling of the vessel with filtering material. Prepared pit undergoes waterproofing, perforated drain pipes (4) are installed at the bottom. Modular structures (6) are used as filtering material and as rainwater collectors. They are covered with underlying bed (7) and loose edges of temporarily fastened canvas of impermeable polymer membrane (3). Then, perforated air pipes (8) are installed and covered with granulated filler (9) over which a solid pavement is laid for use as pedestrian area or roadway.;EFFECT: reliable system operation, simple technologies.;4 cl, 2 dwg
