Zellstoff Pöls AG - Paper machine

The Heinzel Group is building a second large paper machine for the production of bleached kraft paper at the Zellstoff Pöls AG site in Austria. So-called MG papers are used for flexible packaging and show superior market growth. With the new machine, a total of 200,000 tons of MG papers can be produced annually at the Pöls site.
With a diameter of 7.3 meters and a total weight of around 200 tons, the drying cylinder is the largest welded high-precision drying cylinder in the world.

Location: Styria, Austria

Commissioned by: Zellstoff Pöls AG

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.

Semmering base tunnel

We were commissioned by ÖBB Infra to carry out the geotechnical measurements and the control surveys. The extensive scope of services includes the supply of geotechnical instrumentation and data acquisition, the measurement execution including optical 3D displacement measurements and gyro measurements. In addition, geophysical measurements are carried out underground to investigate and evaluate karst-prone mountain sections.

Project description

The 27.3 km long two tube railway tunnel is an essential part of the Baltic-Adriatic Axis (TEN corridor) in Austria and connects Lower Austria with Styria. After commissioning in 2026, the journey time from Vienna to Graz will be shortened by 30 minutes. The tunnel construction work is essentially divided into 3 areas:

  1. Tunnel section Gloggnitz: The 7 km long tunnel will be excavated and blown up from two construction sites: From the tunnel portal in Gloggnitz towards Mürzzuschlag and from the Göstritz access shaft towards Gloggnitz and Mürzzuschlag.
  2. Tunnel section Fröschnitzgraben: With a length of about 13 km, this middle section is the longest. Tunnel driving is carried out in two directions from the 2 access shafts that are more than 400 m deep. The approximately four-kilometer long section towards Mürzzuschlag is excavated and blasted, the approximately nine-kilometer long section towards Gloggnitz is created with two tunnel boring machines. The excavated material is taken to the nearby Longsgraben landfill. The cavern at the foot of the shaft will be converted into an underground emergency stop.
  3. Tunnel section Grautschenhof: The approx. 7 km long section will be excavated and blasted via two access shafts with two tunnel drives each -one per tube -in the direction of Mürzzuschlag and in the direction of Fröschnitzgraben.

Place: Lower Austria/Styria; Austria

Koralmtunnel

Since the beginning of the project in 2004, we have been working on all contract sections, either on the part of the client or the companies carrying out the construction. Our entire range of services is used for tunnel construction, ranging from network and control surveying by means of gyroscopes to carrying out geotechnical measurements and instrumentation with data acquisition and processing up to tunneling control and supply of control systems for the TBMs.

Project description

The 33 km long railway tunnel is the centerpiece of the new high-performance line between Graz and Klagenfurt. It consists of two single-track tunnels with cross passages at 500 m intervals. The maximum overburden is 1200 m. An emergency stop is planned in the middle of the tunnel. The center distance of the two tunnel tubes is about 40 m, in the area of the emergency stop about 50 m.

Work on the approx. 10 km long exploration tunnels and shafts began in 2004. Work on the main tunnel has been in progress since 2009. The tunneling is carried out in cyclical tunnelling and for the most part with a total of 3 tunnel boring machines. Release for traffic is planned for 2026.

Brennerbasistunnel

The tunnel is the centerpiece of the railway axis Verona -Munich and consists of two single-track tubes that run at a distance of 40-70 m and are connected with cross passages at intervals of 333 m. The tunnel is located in the middle of the railway axis Verona -Munich. In addition, a continuous exploratory tunnel will be constructed in the middle between the two main tunnel tubes. The BBT will have a total length of 64 km, making it the longest underground railway link in the world. In Innsbruck, the BBT will lead into the existing railway bypass. The new two-tube tunnel that is going to be built between Innsbruck and Franzensfeste will be 55 km long.

KW Ybbs - Persenbeug

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.

Metro Copenhagen

Our Danish JV company SMT Denmark ApS was commissioned to carry out the entire geotechnical monitoring for the Cityringen project and the Nordhavnen extension. The scope of services includes the supply and installation of the geotechnical installation equipment with data acquisition and measurement, levelling and 3D displacement measurements (mainly with automatic total stations) as well as sound and vibration measurements. Particularly noteworthy is the implementation of our tunnel information system KRONOS, which handles the entire data management, processing and visualization, alarming and reporting of several thousand sensors.

Project description: 

Cityringen:

The Cityringen project creates a new ring line in the city centre and consists of two 17.4 km long tunnels and 17 new train stations (two of which are transfer stations), all 30 m underground. From a technical viewpoint, the project is extremely complex because the city is at sea level. Tunnelling will be carried out by TBM. For the connection to the operation and maintenance center, tunnels will be constructed using the open construction method.

Nordavnen extension:
The extension consists of two TBM tunnels with a length of 1.8 km and 1.6 km, a rescue and ventilation shaft as well as an underground and an above-ground station.

Sydhavnen extension:
The two 4.4 km long tunnel tubes will be driven with two EPB shield machines. Along the route, 5 new underground station structures will be erected.

Location: Copenhagen; Denmark
