Hamco knows what they're doing when it comes to corrugated steel constructions. For more than 50 years, structures for road construction, civil engineering and industry have been produced and sold in Dinslaken. Even the station hall on the Zugspitze, Germany’s largest mountain, and two research stations in the Antarctic are made of Hamco finished steel parts. Still the biathlon training facility, with a total of around one kilometer of demanding construction work, is thus far the most ambitious project.
The first delivery already two weeks after clarification of the technology
Together with their Russian partners, in 2005 the first thoughts were made after the regional administration in Khanty-Mansiysk had decided to build a year round training center near the biathlon stadium.
A double tunnel facility was conceived which is nestled around a small mountain - and which almost looks like a Formula 1 track from above. The start, the goal and an additional tunnel for the shooting facilities are located in a hall connected to the facility.
The Hamco technology of the corrugated steel construction was offered for the facility for several reasons:
Can be well planned and produced: Even the most ambitious tracks can be extensively pre-planned and also pre-produced. For this a special software at Hamco breaks down the planned course of construction in individual corrugated steel segments. Not easy to do. But proven technology.
Can be well transported: The construction parts can be well transported in spite of the enormous quantity since the steel parts can be compactly loaded and are lighter than concrete finished parts.
Easy to construct and still stable: site the construction is built and then stabilized with soil. This makes the facility extremely stable.
Automatically isolated: The filling in with soil ensures a good basic isolation of the construction – the energy expenses for the cooling in summer thus remain comparatively low.
… there were enough of them in the course of the planning:
Size: With a span of 9 meters and a rise of 6 meters and a length of around one kilometer, there is a large amount of material. Based on the possibility of being able to compactly pack the 4500 corrugated steel elements, the number of the needed trucks is limited to a minimum.
Course: The double tunnel facility not only winds around the mountain, but continuously varying height levels are run through. Also a loop had to be built in order to connect the course direction and the way back. Escape tunnel and cross connections were a further challenge. Parts of the connection elements were specially built in advance as a 1:10 model.
Clarification of the technical details and the production start went hand in hand. In the middle of 2006, the planning of the main tunnel facility began, at the end of January 2007 the last detailed questions about the main tunnel had been answered. Two weeks later the first steel finished parts began their trip to Khanty-Mansiysk on the Irtysh, around 4500 kilometers - as a beeline! In January 2008 the last delivery is expected. And already in the summer of the same year operations can begin.
Multi-purpose facility Middle East :
The first plans are available
The multi-function facility in a Near East state is taking shape. The first planning sketches are available - two kilometer track, at times through a shopping mall. Those are the ambitious plans. More on this...
