SWIMMING POOL Russian patent published in 2009 - IPC E04H4/16 

FIELD: construction.

SUBSTANCE: invention is related to construction of swimming pools with overflow system of water treatment. Swimming pool comprises leak-tight body, overflow chute arranged along its perimetre, being separated into two compartments with transversely arranged partitions, overflow rag floating on water surface, which interacts with side of inclined grids inverted to overflow chute, and filtering material with low hydraulic resistance. Overflow chute is created with wall of pool reservoir and connected into wedge-like belt by means of inclined grids. Upper inclined grids are located with clearance to wall of pool reservoir and are fixed with framing planks to cantilever frame hanging over overflow chute to detachable overflow grids, and lower ones rest with framing planks upon wall of pool reservoir. Overflow rag is separated at least into two parts, ends of which are joined with an overlap in areas of installation of partitions that separate overflow chute into two compartments and pressed tightly to internal surface of upper inclined grids with the help of laid layers of block polyurethane foam. Their internal edge is laid along internal surface of angle that joins inclined grids and is pressed with end edge of filtering material arranged along surface of lower inclined grid in the form of polyurethane foam blocks laid tightly to each other and to wall of pool reservoir. Swimming pool is equipped with autonomous filtering plant connected by means of pipeline to mesh filter, which pumps water from single compartment of overflow chute, and to pipeline that sends previously cleaned water to its other compartment for its final filtration and return of treated water into pool reservoir.

EFFECT: invention makes it possible to provide for free access to filtering material in case when it is necessary to replace it and simplifies design of overflow chute.
