The Minden ports at the Minden waterway intersection

The Weserschleuse Minden is a lock in the East Westphalian city ​​of Minden in North Rhine-Westphalia , which has supplemented the shaft lock at the Minden waterway intersection . This means that since August 18, 2017, the connection between the Mittelland Canal and the Weser has also been passable for large motor cargo ships ; after the expansion of the Mittelweser , the port of Bremen will also have direct access to the Mittelland Canal for this type of inland waterway. The new building is located east parallel to the shaft lock on the north descent. With its functional nature, the architectural design does not take up any elements of the old shaft lock. There is no need for towers at the lower head because the new lock is equipped with a mortise gate and a segment gate . The old shaft lock has these towers because the counterweights of the lifting gate are located there.

Construction of the Weser lock in Minden

The new construction office for the expansion of the Mittelland Canal (NBA) started the planning approval procedure in spring 2008 and concluded it with legal effect in August 2009. The construction work could begin on August 24, 2009 with the clearing of the construction site. The actual construction work began in spring 2010 and the lock was scheduled to go into operation in 2015. The estimated construction costs at the time were 70 million euros.

The building yard of the Minden Waterways and Shipping Office was relocated for the major project in 2008. The visitor parking lot and the catering at the shaft lock were closed for the preparation of the construction site in 2009. The old factory halls of the former state shipyard and the Minden Sugar Loaf , an old bunker, were demolished. In May 2011, twelve groundwater measuring points were set up around the construction site in order to monitor the effects of the civil engineering work on the groundwater.

In 2012, the excavation began and the construction of the road bridge in front of the north entrance. The excavation of the lock chambers was brought into a gravel pit near Petershagen with barges.

The concrete work was completed by the end of 2015, the cranes were dismantled, and then the expansion began.

All work was completed in autumn 2016. On August 18, 2017, the Weserschleuse was opened to traffic after seven years of construction and inaugurated with a festive ceremony. The cost was around 80 million euros.

Construction pit

The construction pit for the new lock upstream to the east was planned in four construction phases: First, a bored pile wall was built between the two locks. In the second phase, the construction pit was dug and the first anchor position was set. Phase 3 included further excavation and the setting of the second anchor position. Finally, in phase 4, the third and fourth anchor positions were set and the final construction completed.

Water consumption

Both locks, both the old shaft lock and the new Weser lock, are classified as economy locks, as they collect up to 2/3 of the water during the valley lock in saving containers and then release it again the next time the lock chamber is filled. The old shaft lock has the so-called saving pools to the right and left of the lock basin, a total of 16 pieces, four on top of each other. The new Weserschleuse has three savings basins parallel to the east of the lock basin, two of which are on top of each other. Nevertheless, due to the larger lock chamber for the new large ships, the new lock uses twice as much water as the old shaft lock. When it was completed, it was expected that there would be 4000 lockings per year. The old shaft lock remains in operation in order to take advantage of the savings potential.

Connection

With the expansion of the Weser lock to accommodate the capacity of large motor cargo ships, it is now possible to get from the ports in Bremen via the Mittelweser and Weser locks into the Mittelland Canal. From here, these ships can go via the Ruhr area to the Rhine and thus to Basel. This opens up new opportunities for the waterways in the logistics competition.
