Lock Herne-Ost

Map of the canal with ports, locks, etc. v. a. m.

The lock Herne-Ost belongs - from the Rhine - to the last of the five canal stages of the Rhine-Herne Canal in Herne . The twin lock is at canal kilometer 37.26. Herne-Ost was put into operation in 1914 as the easternmost of the original seven canal stages of the Rhine-Herne Canal.

The Herne-Ost lock system was renewed between 1986 and 1992. The new lock chambers are each 190 meters long and 12 meters wide. The jamb depth (water depth at the upper gate) is 4 meters. A rotating segment gate forms the end to the upper water . Stem gates close the chambers to the underwater. The difference between the upper and lower water is 12.8 meters. Locking takes approx. 14 minutes, not counting the entry and exit times of the ships.

The two lock chambers are connected in such a way that the draining water from one chamber can be used to fill up the other until there is a tie. Hence the name twin lock . The second half of the water is then drained into the underwater, the other, half-full chamber is filled from the upper water. In this way, the water consumption per lock is halved. Since a canal is a stagnant body of water and not a river, the water loss from the headwater at the locks has to be compensated for by pumping back, which is why this canal stage, like all others, is equipped with a pumping station (see also Hamm water transfer ).

The branch canal of the Dortmund-Ems canal from Henrichenburg to Herne, which was added to the Rhine-Herne canal in 1950 , flows into the port of the Friedrich der Große colliery above the current lock .

At the end of the pier between the lock entrance and the Herne-Ost marina stands the Reemrenreh sculpture by Bogomir Ecker , which was erected in the Ruhr area as part of Emscherkunst.2010 during the Capital of Culture year .
