Reconstruction of ice aprons of the Charles Bridge

Reconstruction of ice aprons of the Charles Bridge
After the huge ?oods in 2002 the Charles Bridge ice aprons were severely damaged and required a complex reconstruction. It consisted in complete removal of the backfill both inside and outside of the ice aprons, dismantling of the upper structure of all old ice aprons and subsequent incremental extraction of old wooden piles and other elements (e.g. steel rails) that were left on the riverbank during previous reconstructions in the past. New wooden piles from red oak were then driven into the riverbed that was beforehand eased by pre-drills with a continuous light auger. The new piles are propped against the bedrock. This was not achieved by any of the previous reconstructions. After fitting in the piles the complete new upper part of ice aprons was installed. Some of the original elements were left at ice aprons capitals to provide historical continuity of the structure. The finishing works included replacement
of ice aprons back?ll with quarry stone.


In total: 7 pieces of ice aprons,
Excavation of deposit: 1990 m3,
Extracting of piles: 238 pcs.,
Ramming of piles (red oak): 105 pc,
Refilling of the stone back?ll to ice aprons: 630 m3,
Upper structure: approx. 160 m3 of circular beams from red oak.
