Lagoon type swimming pool

Abstract

A lagoon type swimming pool ( 10 ) with skimmer take-up means or similar, comprises a tank with curved or sloping walls formed from an excavation in the ground or from a work above the ground, on which a layer of rubber -like waterproof material, e.g. EPDM synthetic rubber ( 11 ) is laid to form the water containing basin, said swimming pool comprising a plumbing system with delivery conduits ( 12 ) and return conduits ( 13 ) connected to a distribution unit ( 14 ) comprising water filtering and antibacterial treatment systems as well as hydraulic pumps for the functioning of the system. The delivery of the water inside the tank is achieved by means of a tubular type distribution system ( 15 ) in which the individual conduits are provided with a series of holes; furthermore, one or more layers of high porosity or water permeable material are applied over said tubular distribution system ( 15 ).

         12 . A lagoon type swimming pool with skimmer take-up means or similar, comprising a tank with curved or sloping walls formed from an excavation in the ground or from a work above the ground, on which a layer of rubber-like waterproof material, e.g. EPDM synthetic rubber is laid to form the water containing basin, said swimming pool comprising a plumbing system with delivery conduits and return conduits connected to a distribution unit comprising water filtering and antibacterial treatment systems and hydraulic pumps for the functioning of the system; wherein the delivery of the water inside the tank is achieved by means of a tubular type distribution system in which the individual conduits are provided with a series of holes, and in that one or more layers of high porosity or water permeable material are applied over said tubular distribution system. 
     
     
         13 . The swimming pool of  claim 12 , wherein the holes of the conduits in said tubular type distribution system are positioned at a predetermined distance from each other, and in that the diameters of said holes have predetermined dimensions. 
     
     
         14 . The swimming pool of  claim 12 , wherein the perforated tubular distribution system is surmounted by one or more of the following successive layers:
 a first layer made of perforated or microperforated fabric or thermoplastic material, in particular polypropylene or other similar material, following the trend of the tubular elements which are thus covered by said first layer;   a second layer of inert materials and resin, where the inert materials comprise granules in quartz or stone or various material, including synthetic material, with a predetermined granulosity, mixed in a resin mixture;   a third layer consisting of a net in glass fibre, polypropylene, polyethylene or other similar material designed for the same purpose;   a fourth layer consisting of a finishing mixture made from an agglomerate of sand and/or granular material having a predetermined granulometry mixed with resin in a predetermined percentage.   
     
     
         15 . The swimming pool of  claim 14 , wherein the granular inert material comprises the following materials in the form of grains or granules:
 quartz;   marble;   glass.   
     
     
         16 . The swimming pool of  claim 14 , wherein the layers positioned above the conduits are porous or anyway permeable to water. 
     
     
         17 . The swimming pool of  claim 14 , wherein the conduits are positioned in any way, in geometrical concentric circles, in a web or in variously arranged distribution lines depending on the shape and size of the volume. 
     
     
         18 . The swimming pool of  claim 14 , wherein the resin making up the binder consists of epoxy resin or mono-component resin or any other adhesive material which maintains the granules with a certain stability, guaranteeing the porosity and thus allowing the water to pass from the tubular conduits to the basin. 
     
     
         19 . The swimming pool of  claim 12 , wherein the bottom of the swimming pool is covered with a layer of sand. 
     
     
         20 . The swimming pool of  claim 14 , wherein said second layer comprises granules with granulosity indicatively between 1 cm and 7 cm, mixed in a percentage of 1 to 6 kg of resin with 50 kg of granules. 
     
     
         21 . The swimming pool of  claim 14 , wherein said third layer has a mesh indicatively between 0.5 cm and 6 cm. 
     
     
         22 . The swimming pool of  claim 14 , wherein said fourth layer comprises sand or granular material with granulometry between 0.1 cm and 1 cm mixed with resin in a percentage between 2 to 6 kg for every 50 kg of sand.
