Performance period: 2018 – 2019

GEODATA services:

The rolls of a paper machine require a high-precision alignment, especially for parallelism. In order to meet these requirements, a high-precision network for SMR adapters over an area of 130 m x 25 m and a total height of approx. 20 m was created before the beginning of the assembly work. This network serves as the basis for all stakeout, setup and control surveying activities throughout the entire construction period. This procedure made it possible to precisely align the steel structure in advance, which made the alignment and assembly of the rollers much easier and saved a significant amount of time.

Another challenge was the installation of the Yankee cylinder. The lower half was levelled exactly in front of the hall to facilitate assembly of the upper half. After assembling the two halves, the entire Yankee cylinder was exactly aligned by using the prepared axle markings and removed.

HPP Ybbs - Persenbeug

  Austria

The power plant has 7 machine units, six of which are vertically installed Kaplan turbines and one Kaplan bulb turbine. The measurement was carried out on machine sets 4, 5 and 6. The aim of the survey was a target-performance comparison of the guide vane positions in the guide vane as well as a geometry determination. The contour of the impeller casing was also determined by a target/actual comparison.

Project description:

The VERBUND power plant Ybbs-Persenbeug was Austria’s first power plant on the Danube and is located in Lower Austria. The interior of the power plant has been undergoing modernization since 2014. One machine set (turbine and generator) is renewed each year, and all six vertical machine sets are to be replaced by 2022. This will significantly increase the power generation of the power plant. The resulting additional generation corresponds to the annual electricity consumption of 22,000 households.
The 460 m long dam wall holds back the Danube over a length of about 34 km and up to a height of 10.9 m. The dam will be built on the banks of the Danube. The volume of the reservoir is approx. 74 million m³, the targeted water level is 226.2 m above sea level.
The two locks are located at the left, northern end of the dam, each with a usable length of 230 m and a usable width of 24 m. 
The weir consists of 5 weir fields with a width of 30 m each and is located in the middle of the dam wall.

S 21 Lot 1A and 1B, Filder Tunnel & Tunnel Ober-/ Untertürkheim

  Germany

With a length of approx. 9.5 km, the Filder Tunnel is the longest tunnel in the Stuttgart-Ulm project. Starting from the main station, the tunnel climbs an average gradient of 16 ‰ from the valley basin to the airport, overcoming a height difference of approx. 155 m. The “Ober- /Untertürkheim” tunnel is an approximately 6 km long tunnel that leads from Stuttgart main station in the direction of Ober-/Untertürkheim. The particular challenge here is tunneling under the Neckar river.

Project description

Lot 1A
The 9.05 km long Filder Tunnel consists of two parallel single-track tubes and connects the southern end of the new underground station in Stuttgart with the Filder plain. The tunnel is divided into three parts:

  • The Upper Filder Tunnel was excavated using a shield machine in multi-mode.
  • The Middle Filder Tunnel was built over a length of 1.1 km through the Upper and Lower Bunter Marl using the NATM construction method.
  • The Lower Filder Tunnel, with a length of 4.1 km, crossed the anhydrite-bearing unleached gypsum keuper. For this, the TBM used had to be converted into an open shield machine.

Lot 1B
With its two parallel single-track tunnels, the Ober-/Untertürkheim feeder line will connect the southern exit of the new underground station with the existing line. The approach consists of a main tunnel that leads from the junction structure at the northern end of the Lower Filder Tunnel in an easterly direction to the Wangen junction structures. Shortly before Wangen is the Ulmer Straße intermediate access shaft, via which the main tunnel is excavated to the west and east to the Wangen branching structures. From Wangen, a section leads northwards, where it reaches the open construction method of the Untertürkheim construction pit after around 1 km. A second section leads from the Wangen junction to the south-east and ends after almost 1.4 km in the Obertürkheim excavation pit.

At the “Hauptbahnhof Süd” emergency access road, a 240 m long access tunnel leads directly into a complex branching structure, in which four tunnel tubes lead into two large double-track tunnels directly in front of the underground station. This section is located directly underneath densely built-up areas with overburdens of between 20 m and 55 m and was constructed with leading pillar tunnels.
