The Untertürkheim barrage from 1923 consists of a four-span weir with a double-chamber lock. It is located directly below the port of Stuttgart . A road bridge with tram tracks runs across the weir and connects the districts of Wangen and Untertürkheim. The lock from 1958 is remote-controlled from the remote control center in the Obertürkheim barrage.
Redevelopment
The weir system was put into operation in 1923. Due to the destruction of the war and several renovation measures, the shape of the weir system and road bridge had changed several times during this time.
The lock and drive design were now over 80 years old. The increasing number of malfunctions in the drive gave rise to a detailed inventory of the entire weir structure. This mainly included the concrete structure, as it was known that considerable damage to the structure had to be repaired during earlier renovation measures.
The inventory led to the result that locks and drives have to be replaced by designs that correspond to the current state of the art. In addition, the concrete structure was in a condition that required a thorough renovation.
The new weir construction
The basic overhaul essentially comprised the following measures:
- Replacement of the existing drive and lock construction with new roller gates with attachment flaps. In the future, each lock will be equipped with two drives with lifting chains.
- Demolition of the old weir pillars on the upstream side of the road bridge and erection of new weir pillars including foundation. Each new weir pillar will be equipped with a pillar house due to the accommodation of the gearboxes, which will be higher and in the upper area wider than before due to the increased space requirements.
- Buoyancy protection of the defensive floors by means of anchoring, reinforcement of the existing defensive floors, backfilling of the cavities between floor and building ground.
- Construction of an underwater inspection seal to enable the defensive floors to be drained for inspections in the future. The design of the weir system is changed by the requirements of operational safety, ease of maintenance and hydraulics. The Federal Institute for Hydraulic Engineering (BAW) creates a reference to the industrial surrounding architecture in its architectural design. The floor plan and volume are created from the aerodynamically optimized basic shape of the weir piers. The resulting pillar house shape appears boat-shaped.
Construction process
The basic repairs had to be carried out while the weir system was still in operation. Two weir fields per construction section, starting on the left side of the river, will be drained. This made it possible to completely rebuild the pillar in between.
This required the construction of a construction pit made of sheet pile walls from the water. The flood discharge during the construction period was ensured. This was examined on the basis of extensive model tests at the BAW.
Work began at the beginning of 2007 with the dismantling of the existing weir locks and the construction of the construction pit enclosure in fields 1 and 2. In 2013, the renovation of fields 3 and 4 was completed.
Hydroelectric power plant
The hydropower plant in Untertürkheim was originally built as a steam and hydropower plant between 1899 and 1902. It was the first municipal power generation company in Württemberg. The pioneering work in Untertürkheim continued: in 1924 one of the first and largest Kaplan turbines was installed there. When the Neckar was relocated and canalized in 1923, the new weir was built west of the power plant. The power plant is connected to the Neckar by a canal. The power plant has an output of 1.5 MW .
On August 29, 2013 there was a fire in the generator of the Kaplan turbine from 1924, as a result of which there was a power failure in Untertürkheim.
location
Seen from the Rhine, the Untertürkheim barrage is the 23rd facility.
