Abstract
A leaf for a mitre gate is provided. The leaf for a mitre gate may include: a skin plate intended for withstanding a pressure exerted by a liquid; and at least two uprights respectively located on either side of the skin plate, the uprights being secured to the skin plate. The skin plate is in the overall shape of a cylinder portion, the longitudinal axis of the cylinder being essentially parallel to the uprights. Each upright extends overall according to a generatrix of the cylinder. Each upright includes at least one bearing element, arranged to project relative to the skin plate and each bearing element includes a bearing surface, for supporting the bearing element against a lock wall or another leaf of the mitre gate. The bearing surface of each bearing element is aligned with a plane that is tangential to the skin plate.
