Slat closure for use in narrow plank weir of e.g. ground water regulating system, has bars inserted and locked in fittings from top so that slats are only commonly vertically displaced and lie at each other at horizontal sealing surfaces

摘要

The closure (1) has retaining slats (8.1-8.6) arranged above each other and limitedly individually vertical displaceably provided. The individual retaining slats are coupled by communicating lifting fittings (11, 12) according to a type of an adjustable Venetian blind. Angular locking fittings (10) are arranged at the retaining slats. Locking bars (9) are inserted and locked in the locking fittings from top so that the adjacent retaining slats are only commonly vertically displaced and lie at each other at horizontal sealing surfaces. An independent claim is also included for a retaining slat.
