The Eisenhüttenstadt twin shaft lock , formerly known as the Fürstenberg twin shaft lock, forms the easternmost canal stage in the Spree-Oder waterway federal waterway . It is located in the urban area of Eisenhüttenstadt in the German state of Brandenburg . The lock is the responsibility of the Berlin Waterways and Shipping Office . The maximum height of fall is 14 meters.

history

Friedrich Wilhelm Canal near Brieskow-Finkenheerd

The Friedrich Wilhelm Canal , previously the Müllroser Canal, was the first artificial waterway to connect the Spree with the Oder . The canal, completed in 1668, ran from Neuhaus an der Spree to Brieskow an der Oder. It was about 17 miles long. For 200 years this waterway was the most important inland waterway connection between Hamburg , Berlin and Wroclaw .

The reduction in freight costs associated with canal shipping had positive economic effects on the cities mentioned. From the 1860s onwards, the canal increasingly reached its capacity limit, so in 1886 it was decided to build the Oder-Spree canal . Part of the Friedrich Wilhelm Canal, about 11.3 kilometers from the former Buschschleuse, 2.5 kilometers northeast of Neuhaus, as far as Schlaubehammer merged with the Oder-Spree Canal. The section from the Wergensee to the Oder-Spree Canal, known as the Neuhauser Feeding Canal, has served to feed the apex of the canal since 1892.

Twin shaft lock

The foundation stone for the twin shaft lock was laid on August 1, 1925. The structure is founded on a layer of clay about 20 meters below the site. 130,000 m³ of cast concrete and 6,000 t of steel inserts were required for the construction of the lock. It was opened to traffic on November 1, 1929.

The lock system consists of two adjacent chambers with a center distance of 34 meters, the main operating building and smaller auxiliary buildings. Each chamber is 130 meters long and 12 meters wide. The lock chambers are made of reinforced concrete. The design of the descent structure as a twin lock enables rapid handling of shipping traffic.

The double lock was planned and built as an economy lock with a special operating mode. As a rule, one chamber is located in the upper water, the other chamber in the lower water. During locks, one chamber is simultaneously channeled up and the other down. First, the water level in both chambers is leveled through connecting channels based on the principle of communicating tubes. Then one chamber is emptied to the underwater by means of roller wedge gates and the other chamber is filled from the upper water. This theoretically enables a 50 percent water saving compared to individual locks. The lock process takes about 30 minutes. With each lock, around 11,000 cubic meters of water are used from the sewer, which has to be pumped back into the upper section by means of connected pumping stations. The heads of the locks are closed by folding gates, the heads by lifting gates.

To the east, directly at the lock, a road bridge (Gubener Straße / L 372) and about 50 meters further a railway bridge crosses the underwater.

Fürstenberg lock stairs

In 1889, a three-stage lock staircase with upper, middle and lower locks was built south of the town of Fürstenberg / Oder to connect the new canal to the Oder. On a canal stretch of around three kilometers, they overcame the mean drop of 14 meters to the Oder. Remnants of the locks and the descent canal have been preserved.

Water supply for the apex posture

Each lock process creates water losses in the apex of the Oder-Spree Canal between the Kersdorf and Fürstenberg / Oder locks , as this section of the canal lacks natural inflows. In order to compensate for these water losses, the Neuhaus pumping station was built in the Neuhauser feed channel as early as 1892 . By means of the pumping station, water is pumped from the Wergensee into the top of the Oder-Spree Canal via the canal . In 1916/17, the Fürstenberg pumping station was added to the lower outer harbor at the Fürstenberg lower lock . This pumping station pumped water from the Oder into the section between the upper lock and the middle lock of the canal. With the completion of the twin shaft lock in 1929, a new feed channel was built from the pumping station at the lower lock to the upper outer port of the twin shaft lock.
