Method for making aquatic pools and in particular for swimming pools

Abstract

The invention concerns a method for making aquatic pools such as swimming pools, which consist in covering the panels ( 1 ) of a cavity with concrete. The invention is characterised in that it comprises the following steps: preparing a mixture of cement ( 2 ), sand ( 4 ) and fibres ( 3 ); transferring said mixture to a spray nozzle; simultaneously spraying said mixture and water on the wall to be covered, with the spray nozzle ( 12 ). The invention also concerns a pool, in particular for swimming obtainable by using said method. The invention is applicable to aquatic pools.

1 . Process for the production of swimming pools, consisting in covering the walls of a cavity with concrete, characterized by the fact that it comprises the following steps: 
 preparation of a mixture of cement, sand and fibers.    transfer of said mixture to a spray nozzle.    simultaneous projection of said mixture and water on the wall to be covered, by the spray nozzle.    
     
     
         2 . Process according to  claim 1 , characterized by the fact 
 that spraying on the wall is carried out at a flow rate greater than 6 m 3 /h.    
     
     
         3 . Process according to  claim 1  or  2 , characterized by the fact 
 that there is used a mixture comprising between 30 and 70 kg/m 3  of fibers.  
 
     
     
         4 . Process according to any one of  claims 1  to  3 , characterized by the fact 
 that the fibers are steel or polymer material.  
 
     
     
         5 . Process according to any one of  claims 1  to  4 , characterized by the fact 
 that the mixture comprises between 17 to 22% by weight of cement.  
 
     
     
         6 . Process according to any one of  claims 1  to  5 , characterized by the fact 
 that there are used fibers whose length is from 3 to 5 cm and whose ends are bent to form two wings.  
 
     
     
         7 . Process according to any one of  claims 1  to  6 , characterized by the fact 
 that prior to spraying, there is positioned a lining of wattle on the wall to be covered.  
 
     
     
         8 . Pool, particularly a swimming pool, adapted to be produced by use of the process according to  claim 7 , 
 characterized by the fact 
 that its walls, at least the side walls, are covered with a composite material constituted by at least one layer of wattle embedded in a concrete based on cement, sand and fibers.
