FIELD: building, particularly individual and public swimming pool structures provided with overflow water filtering system.

SUBSTANCE: swimming pool has sealed many-sided body and overflow channel arranged along body perimeter and used for water purification. Front wall of overflow channel is below rear wall thereof and has end flange inclined downwards in swimming pool basin direction. Overflow channel caps are provided with partitions located inside the caps. The partitions have wedge-like parts extending downwards and having the first sides facing overflow channel. End plates of the partitions are in plane of end flange of front wall. Another partition surfaces face water pool basin interior and are adapted for water passing into overflow channel. Inner edge of floating overflow mat arranged along end flange of front wall is connected to above end flange. Overflow mat cooperates with end plates of partitions facing overflow channel. Overflow mat floating on water surface has apron with semicircular cross-section depending therefrom and extending around the full overflow mat periphery. Outer edge of the apron and inner edge of overflow mat are laid on inclined end flange of the front wall so that filtering material is disposed in-between. The filtering material is fibroporous polyethylene. Outer edge of the apron and inner edge of overflow mat are pressed with framing strap of inclined grid from top thereof. Part of apron surface arranged along outer edge thereof is provided with orifices closed with filtering members made as microstrainers for fine water cleaning. Inner inclined grid surfaces facing overflow channel and closing overflow channel are in plane parallel to inclined end flange surface of the front overflow channel wall plane and cooperate with working overflow mat surface. Folded downwards flanges of framing strap close filtering material from swimming pool basin side and are spaced apart therefrom. Filtering material is formed as sealing member.

EFFECT: simplified structure and maintenance.
