The power plant / pumping station is on the right bank, the lock for large shipping is on the left bank and the boat lock is on the right. In between is a triple weir. The attitude Kelheim covers 15.13 km length to the barrage Riedenburg .

Weir

Three fields with a clear width of 15 meters each form the weir system between the locks on the left and the power plant / pump system on the right. The target is 346.6  m above sea level. NN . On the right bank there are boat ramps in the upper and lower water.

Pumping station / power station

The Kelheim pumping station operated by Rhein-Main-Donau AG is designed to be reversible using pump turbines , so it can also be operated as a power station. It is the first of five pumping stations on the south ramp of the Main-Danube Canal and part of the Danube-Main crossing . With its five identical units, it can operate max. Pumping 35 m³ / s, of which 3/5 of the amount is intended as a low water increase in the Regnitz-Main area and 2/5 are planned as process water for the locks.

The Kelheim and Riedenburg sections are not canal sections , but river sections of the Altmühl . At higher discharge values ​​of the Altmühl there is no transfer from the Danube and the plant can be operated as a power plant. The installed capacity in operating mode as a hydropower plant is 2600 kilowatts , with a head of 8.4 meters and a total flow rate of the five machine sets of 35 m³ / s. The pumping station was put into operation in 1987. The monitoring and control is effected by the WSV from the traffic center Main-Donau Gössel Thal (RVZ MD) from.

Ship lock

The Kelheim lock is a single lock with a usable length of 190 m and a usable width of 12 m. It is closed at the head with a lifting gate and at the lower head with a mortise gate . The average height of fall is 8.40 m. It is operated remotely from the WSV control center in Dietfurt .

bridge

The bridge system has a total structure length of around 127 meters with a bridge width of around nine meters and a roadway width of around six meters. There a municipal road leads over the canal, which connects the state road St # 2230 with the district road KEH 15 . It consists of two parts, the lock bridge and the weir and power station bridge .

Anti-tank barrier

When the system was built, an anti-tank barrier was also installed at the pumping station / power station . In the event of a defense, steel girders could have been inserted into numerous shafts, which were recognizable as covers in the road and sidewalk pavement, and these were stored in a garage-like locking material store southeast of the bridge. The manhole covers in the carriageway are no longer recognizable today due to an asphalt surface that has been applied in the meantime .

history

The barrage was built between March 1976 and December 1981.
