Sliding gate (hydraulic engineering)

from Wikipedia, the free encyclopedia

When sliding or rolling door in is hydraulic particular type of lock gates , respectively. They belong to the lock gates with a horizontal movement path.

Layout and function

A sliding door opens and closes horizontally and laterally to the axis of a ship lock . As a rule, it is used to close a very wide and particularly large lock chamber and consists of a wagon-like steel construction that runs on rails or hangs on a rail construction. Special sealing systems guarantee low water loss during the lock process.

Examples

  • Sliding gate of the Kaiserschleuse Bremerhaven

  • Sea lock in Leer

  • Great sea lock Emden

Other types of lock gates

  • Lifting gate as a protective board with vertical movement in the direction of the gate level upwards.
  • Folding gate as a single-wing lock gate with a horizontal axis of rotation attached to the floor of the lock chamber.
  • Segment gate as a damming body rotatable about a horizontal axis with a circular cylindrical gate skin.
  • Mortise gate made of two wings (rarely only one wing) with a vertical axis of rotation.
