Reconstruction of a bridge over the Berounka River


Reconstruction of a bridge over the Berounka River
The Lahovický Bridge is situated in the immediate vicinity of the confluence of the Berounka and Vltava rivers in the Prague quarter Lahovice. Reconstruction of the old bridge was conditioned by preserving road transport in 4 traffic lanes, continuous shipment and the least possible restriction of the river flow profile. The reconstruction was carried out in full extent, i.e. including pillar foundations and bridge supports. The project required securing of the construction site with sheet pile cofferdams providing for foundation of pillars in the riverbed below the reach level; carrying out sheet pile cofferdams for foundation of the temporary bridge and cofferdams for positioning of tower cranes for the actual bridge construction.
The foundation works involved even more special foundation technologies – jet-grouting for underpinning flat foundations of the pillars and bored piles for the foundation of Prague supports. The works on building supports in the immediate vicinity of the running road involved use of sheet pile walls anchored by ground anchors. All works carried out in the Berounka riverbed were realised from our own ship mechanisms.
