CA 2722098

A dam construction method utilizing refrigerating technology is provided, the method takes natural water as the material to construct the dam and constructs an ice dam body by utilizing the refrigerating technology. The method includes the following steps: choosing the forms and quantity of ice unit bodies, determining the positions and quantity of frozen contact: points, manufacturing sufficient ice unit bodies by frozen units, choosing heat insulating material with high performance as the heat preservation layer to cover on the outside of the frozen ice unit bodies; temporarily fixing the ice unit bodies; quickly freezing the seams of the ice unit bodies to form a whole ice dam; mounting temporary generating equipment and completing the temporary dam body; thawing the ice dam body after a permanent dam body is completed.

L'invention concerne un procédé de construction de barrages utilisant une technologie frigorifique, le procédé prenant de l'eau naturelle comme matériau pour la construction du barrage et construisant un barrage de glace en utilisant la technologie frigorifique. Le procédé comporte les étapes consistant à : choisir les formes et la quantité des corps unitaires de glace, déterminer les positions et la quantité des points de contact gelés, fabriquer suffisamment de corps unitaires de glace au moyen d'unités solidifiées, choisir un matériau d'isolation thermique à hautes performances formant la couche de protection thermique destinée à recouvrir l'extérieur des corps unitaires solidifiés de glace; fixer temporairement les corps unitaires de glace; solidifier rapidement les joints des corps unitaires de glace de façon à former un barrage de glace complet; monter un équipement temporaire de génération et achever le corps de barrage temporaire; dégeler le corps du barrage de glace après l'achèvement d'un corps de barrage définitif.
