Sluice gate has curved cross-section and is made from composition material for reduced weight

摘要

A sluice gate has a curved cross-section (32) and a vertical generating line; it is made from at least two superimposed sections connected by side members sliding in side wall grooves (30) that take up the load on the gate from the water pressure. The gate has platforms (23, 25) on its upstream and downstream sides, and its components are made from successive layers of glass fabric impregnated with an organic resin.
