(FR) BARRIERE DE PUITS, ÉQUIPEMENT DE PUITS, CENTRALE NUCLÉAIRE, ET PROCÉDÉ D'INSTALLATION DE BARRIERE DE PUITS

Abstract:
(EN) This pit gate includes: a gate body inserted between a pool portion that stores water and a canal portion connected to the pool portion, thereby changing the state of flow of the water; and a seal portion (6) that is accommodated in a groove-shaped accommodating recess formed in the gate body and that seals between the pool portion and the gate body. The seal portion (6) has a low-rigidity portion (10) that is relatively easily deformed by the load from the water pressure from the pool portion side, and a high-rigidity portion (11) that is provided on the pool portion side of the low-rigidity portion and is not easily deformed by the load.
(FR) Cette barrière de puits comprend : un corps inséré entre une partie piscine qui stocke de l'eau et une partie canal reliée à la partie piscine, modifiant ainsi l'état d'écoulement de l'eau; et une partie d'étanchéité (6) qui est logée dans un évidement de réception en forme de rigole formé dans le corps de barrière et qui assure l'étanchéité entre la partie piscine et le corps de barrière. La partie d'étanchéité (6) comporte une partie à faible rigidité (10) qui se déforme relativement facilement sous la charge provenant de la pression d'eau depuis le côté de la partie piscine, et une partie à rigidité élevée (11) qui est située sur le côté de la partie piscine de la partie à faible rigidité et ne se déforme pas facilement sous la charge.
(JA) ピットゲートは、用水を貯留するプール部及びプール部に接続されたキャナル部の間に挿入されることで、用水の流通状態を変化させるゲート本体と、ゲート本体に形成された溝状の収容凹部に収容され、プール部とゲート本体との間をシールするシール部(6)と、を備える。シール部(6)は、プール部側からの水圧に基づく荷重によって相対的に変形しやすい低剛性部(10)と、低剛性部のプール部側に設けられ、荷重によって相対的に変形しにくい高剛性部(11)と、を有する。
