Abstract

Dispositif de protection contre les ondes de pression des ouvrages soumis à un écoulement d'eau. En particulier dans les centrales nucléaires, la chaleur perdue évacuée est très souvent cédée à de l'eau de rivière ou de mer. Il faut pour cela des ouvrages de conduite d'eau (canaux, etc) par lesquels l'eau s'en va la centrale et y revient Pour la protection de ces ouvrages contre les ondes de pression qui peuvent se produire par exemple en cas d'explosion sous l'eau, l'invention prévoit une chambre 3 dans laquelle se trouvent des plaques parallèles 5 placées dans la direction du courant. Ces plaques sont revêtues sur leurs deux faces d'une couche de matière alvéolaire élastique, de sorte que les ondes de pression peuvent être absorbées efficacement dans cette chambre.Device for protection against pressure waves of structures subjected to a flow of water. Particularly in nuclear power plants, the waste heat evacuated is very often transferred to river or sea water. This requires water pipe structures (canals, etc.) through which the water flows. goes to the plant and comes back To protect these structures against the pressure waves which can occur for example in the event of an explosion under water, the invention provides a chamber 3 in which there are parallel plates 5 placed in the direction of the current. These plates are coated on both sides with a layer of elastic foam material, so that pressure waves can be absorbed effectively in this chamber.
