Sluice with mobile barrier for tidal works - has thin section metal barrier with ends mounted in vertical slides driven by motor assembly

摘要

The sluice has a concrete structure of base (1), pillars (2) and roof (3), that define a sluice for the passage of water between the two end piles (2), with small intermediate piles (4) increasing support without decreasing flow. The metal barrier (51) is mobile w.r.t. this concrete structure, and is supported by it. The barrier allows the sluice to be closed and is driven by a motor assembly. The barrier (51) is a flat vertical rectangular panel that has two vertical lateral sides that slide in two vertical slides in the end piles to minimise pile and barrier dimensions.
