Reconstruction of a bridge gallery in the Chotkova Street in Prague

The original structure of a bridge gallery in the Chotkova Street showed generally decreasing capability of transferring loads induced by long-term intensive road and tram transport. A rider wall made of bored piles was designed behind the bridge gallery underside to secure the stability of the road underbed and to accept earth loads. Rider (pile) tops were tied with a continuous girder that was subsequently anchored with permanent earth anchors into bedrock of the Letná hill layers. Composite action of the original bearing structure and the gallery with a newly created wall was achieved by fastening them together with high-strength steel tie bars. The original gallery structure was concurrently reconstructed and redeveloped.
