139 X Nemetschek Structural User Contest 2013 - Category 2: Civil Structures Category 2: Civil Structures 2 Short description │Bridge over Koberný Pond and a Wildlife Corridor The Bridge over Koberný lake and a wildlife corridor at the 87,500 km point of the D3 motorway section running from Tábor to Veselí nad Lužnicí, with a total length of 552.8 m, is located in a non-built-up area which is used for agricultural and breeding purposes. The motorway corresponds to the category D 27.5/120. The concrete pillars, with the cross-sections of 8.0 x 2.5 m, are founded on 19 30-metre piles 1.2 m in diameter. Two pairs of casting carriages were used for the free-cantilever-method construction of the loadbearing structure of the box girder with the variable depth ranging from 2.69 m to 5.89 m. Casting of the girder proceeded symmetrically from 16-metre long balance arms. Metrostav a.s.
