The Berlin Oberschleuse , often just called the Oberschleuse , is a lock on the Landwehr Canal in the Berlin district of Friedrichshain-Kreuzberg . It connects the higher water level of the Oberspree at the lower water level of the Landwehr canal to the bottom lock of the channel. The Oberschleuse is located at kilometer 10.75 of the waterway directly at the junction with the Spree-Oder waterway . The Berlin Waterways and Shipping Office is responsible for operation and maintenance . The call channel is on VHF channel 78. Immediately at the Oberschleuse there is the Schlesische Brücke and the Obere Freiarchenbrücke . They connect the Schlesische Strasse over the Lohmühleninsel with the street Vor dem Schlesisches Tor and the Treptower Puschkinallee.
history
In the 1840s, shipping in the greater Berlin area developed rapidly, so that the barges at the city lock in the Spree Canal sometimes had to wait six to eight days for the lock. The Mühlendamm in the Spree prevented a continuous use of the Spree for shipping. A bypass became necessary and the Landwehr Canal was planned and implemented.
The upper lock was built in 1848 as a two-aisled tow lock with staggered heads. The chamber length was 140 feet (43.94 meters). The chamber length between the jamb tips was 160 feet (50.22 meters) and the chamber width was 32 feet (10.04 meters). The gate width was set at 24 feet (7.53 meters) with consideration for smaller steamships that might have to be locked. For the construction of the upper lock, a new section of canal about 500 meters long had to be dug. The lock walls were built from Rathenow bricks and the gates were made of oak. Granite was used for the turning niches. After the Second World War , as a result of political developments and the division of the city, the canal was expanded and brought to an average water depth of two meters. Due to the increased shipping traffic, the lock was enlarged at the same time. The upper lock was converted into a boiler lock almost 20 meters wide. As an absolute novelty, the lock has two gates in the lower part that are next to each other and enable two ships to exit the chamber in parallel. The lock walls have now been replaced by steel sheet pile walls. The bottom of the lock is permeable and has a rock fill to protect it against the screw water of the ships. The lock chamber is filled or emptied via the hydraulically driven gates. The official chamber dimensions are given with the usable chamber length of 66.60 meters, the chamber width of 19.50 meters and the gate width of 8.50 meters. The total length of the lock chamber is 72.00 meters.
