Tunnel Day

The Austrian National Committee of the ITA (International Tunneling Association) organizes the Austrian Tunnel Day in conjunction with the Geomechanics Colloquium. The Tunnel Day focuses on presenting the latest state of the art of Austrian and international engineering concepts in design and construction.

Recent creative developments in design, construction, and operating methods in tunnelling are presented.

The application of those new design and construction concepts will promote further innovation in future tunnelling projects.

12th Austrian Tunnel day, 10/13/2021

On Wednesday, October 13th, 2021, the 12th Austrian Tunnel day will take place.

The sessions topics are:

  • Special challenges at large construction sites New regulations for tunnelling
  • Innovation and processing of tunnel construction projects
  • Presentation Innovation Award Tunneling Deadline: 07/31/2021
  • Handling of tunnelling projects - Future ways

Participation is only possible in combination with the Geomechanics Colloquium.

Kühtai storage plant

With a usable storage capacity of about 31 mio m³, the new Kühtai reservoir is about half the size of the existing Finstertal reservoir. The dam is designed as a natural stone infill dam with a central earth core and a height of 113 m from the original valley floor to the dam crest. The full reservoir level is at 2,140 m above sea-level. All of the material used for the infill dam is extracted on site from the future reservoir and the tunnel excavation.

Similar to the two existing dams, natural stone and structural elements will be used for the airside dam surface to blend in the structure with the natural surroundings in the best possible way.

 

The Kühtai 2 power station with its headrace channel – a tunnel 4.5 m in diameter – connects the new Kühtai reservoir with the existing Finstertal reservoir. The power station is built completely underground in a rock cavern and is designed for pumped storage operation. Two pump turbines form the heartpiece of the station. These turbines are reversible, meaning their function and direction of rotation can be turned around: in turbine operation, up to 90 m3/s of water are flowing in the headrace channel from the Finstertail reservoir to the Kühtai reservoir with the turbine driving the generator, causing the generator to feed electricity into the grid.

 

The stream adduction – a tunnel 4.2 m in diameter and 25.5 km in length – with its six water intakes opens up an additional catchment area in the middle, eastern part of the Ötztal valley and the head of the Stubaital valley. The harnessed water is fed into the Kühtai reservoir at a slight gradient. Due to local conditions, two of the water intakes are situated slightly below the stream adduction; a pumping station is used to raise the water drawn off there to the level of the adduction.

 

As a general principle, the amount of water drawn off at the intakes conforms to ecologically compatible levels. Natural flow dynamics are maintained even if at a lower level. In the winter months no water is drawn off at all.

Sight Seeing Programm

On Thursday, October 8th, we are offering accompanying persons the following social program:

The Attersee is the largest lake in the Salzkammergut and, thanks to its turquoise blue water of drinking water quality, is one of the most popular bathing lakes in Austria. In addition to various sports opportunities, the region also offers numerous  attractions.

First, our tour leads to the beautiful late Gothic parish church of Gampern, where you can admire one of the three most famous Gothic winged altars in Upper Austria.

Then we go to Seewalchen where we visit the Gexi Tostmann traditional costume museum.

Afterwards we enjoy a walk on the promenade with a view of the lake, passing Villa Paulick, a historic summer villa that is a listed building.

A visit to the Klimt center in Schörfling, a walk on the Klimt theme trail, in the Klimt garden and a boat trip on Lake Attersee open up the Klimt trails and its impressive motifs on land and from the sea side.

Of course, lunch as well as coffee and cake are also provided.
