Four. The composition of the sluice and the functions of each part

Upstream connection section → lock chamber section → downstream connection section

(Guiding water flow into the lock chamber smoothly) (Adjusting water level and flow) (Energy dissipation , anti-collision)

⒈Sluice chamber: bottom plate, gate pier, gate, (breast wall), working bridge, traffic bridge.

⒉Upstream connection section: wing wall, covering, bottom protection, upstream anti-scouring trough, upstream slope protection.

⒊Downstream connection section: wing wall, protection tank, sea diffuser, downstream anti-scour groove, downstream slope protection, downstream drainage (reverse filter, drainage hole).
