The most modern biogas system in the world goes into operation

PASCHAL supplies round formwork and wall formwork for the Bürstadt Energy Park
TTR round formwork and Modular/GE wall formwork for concrete buildings of the highest order

In May 2007, the construction company Wilms GmbH & Co.KG started the skeleton building work as commissioned by the company Energiepark Bürstadt GmbH & Co Biogas KG. The turnkey project was budgeted to cost 11 million Euros. This included the building for the power station, the office building and four “smaller” reservoirs with diameters of 18.0 metres and two “large” round reservoirs with diameters of 28.0 meters. Also, there is a 4,000 square metre sole plate for silage that is subdivided and surrounded by a 4 m high wall. A warehouse with 1,000 square metres holds the bio waste and also large biological solids.

Walls
The straight walls were formed by the company Wilms GmbH using their own GE-elements. These large-surface elements come from the MODULAR/GE series; whilst the numerous different grid elements can also be used for manual formwork, the GE-elements are up to 2.75 metres high and 2.0 metres wide.
The trapezoidal girder round formwork (TTR) with adjustable radii was met with great enthusiasm. The world’s leading technical product with 21 mm thick, 15-layer plywood made of Finnish birch that can be nailed is the only system that can be flexibly tigthened to a radius of 2.5 metres where other systems would break or form waves. As a “dual support” it can be even used for radii up to 1 metre with an 18-mm plywood. The formwork here is stable, round and accurate and does not distort even if it is moved several times. The circumference can be formed to the exact centimetre and without any on-site compensation work. One square metre of formwork surface can absorb up to 60 kN of fresh concrete pressure even though there are only 0.28 ties per square metre. It is exactly these benefits that count especially when producing complex constructions such as round reservoirs. Thanks to the speedy relocation process, the extremely low number of ties and the fact that the formwork does not need to be additionally supported with belts or re-rounded, all the work was performed comfortably. safely quickly and efficiently. The low number of ties also improves the quality of the concrete surface.
