DESCPRIPTION OF PROJECT
The double lock situated east of the canal bridge over the Elbe is composed of two parallel locks with 3 water saving chambers each, allowing motor freight ships of 110 m length or push tugs of up to 185 m length, 11.4 m width and of 2.8 m load draught to descend from the Mittelland Canal into the Elbe-Havel-Canal, thereby overcoming a difference in level of more than 18.55 m. The Mittelland canal is situated approx. 15 m above ground level. The outer harbour is provided with a clay lining of 0.40 m thickness. Scour protection is ensured by riprap placed on a geotextile filter layer. The lock is founded on piles. The upper lock head is provided with a radial gate, the lower lock head with mitering gates. All gates are oil-hydraulically operated. The lock also includes a pumping station which pumps water from the Elbe-Havel Canal into the Mittelland Canal.
