FIELD: construction, particularly swimming pool structure.

SUBSTANCE: swimming pool comprises overflow gutter and longitudinal water-tight partition extending along the full overflow gutter length and separating the overflow gutter into two chambers. Outer chamber is used for water self-cleaning. Inner chamber is adapted for forced water cleaning. Inner edge of floating overflow mat is secured to bent flange of water-tight partition. V-shaped partition is made as structure separated from overflow gutter lid and including rods having rectangular cross-sections and bent to create V-shaped members. Rods are connected with each other in upper parts thereof with framing member adapted to receive removable lid of overflow gutter. Lower ends thereof are secured with each other through support plate adjoining front wall of overflow gutter. One side of V-shaped grid has horizontal section extending from bent part of another V-shaped grid side facing swimming pool bowl up to contact thereof with bent flange of watertight partition. Filtering material with low flow resistance is arranged along the full length of outer chamber or along part thereof. Said filtering members may be formed as at least one layer of foamed polyurethane block layer including blocks tightly pressed one to another and to overflow gutter walls so that space is created over gutter base. The space defines drain channel communicated with swimming pool bowl through at least one pipeline. Drain channel of inner chamber is connected with sucking electric pump pipe through pipeline. Electric pump has pressure pipe secured to drain channel of outer overflow gutter chamber by means of pipeline.
