Des tuyaux incurvés sont reliés à demeure à deux extrémités de chaque planche de batardeau, les extrémités supérieures des tuyaux incurvés étant respectivement en communication avec des premiers trous d'admission d'eau et des premiers trous de vidange ménagés dans les planches de batardeau ; pour chaque paire de planches de batardeau adjacentes, le premier trou d'admission d'eau dans une planche de batardeau est en communication avec le premier trou de vidange dans l'autre planche de batardeau ; et les premiers trous d'admission d'eau, les premiers trous de vidange et les tuyaux incurvés sont reliés afin de former un canal d'écoulement en lacet. Un second trou de vidange est ménagé dans la plaque inférieure, une extrémité du second trou de vidange étant en communication avec l'extrémité inférieure du canal d'écoulement en lacet, et l'autre extrémité du second trou de vidange étant en communication avec une face aval de la plaque inférieure. Une extrémité d'un second trou d'admission d'eau est en communication avec l'extrémité supérieure du canal d'écoulement en lacet, et l'autre extrémité du second trou d'admission d'eau est en communication avec une face amont de la plaque supérieure. Une vanne est disposée dans le second trou d'admission d'eau. La présente invention peut efficacement atténuer les effets néfastes d'un remplissage d'eau à haute pression sur une plaque inférieure d'un sas d'écluse.
