Storeforth Lane Bridge, Chesterfield, Derbyshire – UK

Project Overview

The brickwork of this bridge’s South East wing wall was exhibiting an increasing number of stress cracks and was also beginning to bulge. The bridge structure was subsequently identified as requiring some remedial works to stabilise the wall from further rotational movement and prevent possible collapse which would lead to the closing of the four rail lines being carried.

Solution

Five 125mm diameter core holes were cut through the wall at calculated centres and 30° below the horizontal. Mechanical anchors, with a 120 year design life, were then installed to a driven depth of 8m, proof loaded and locked off against the facing wall using an inverted pattress plate. These pattress plates were used to provide an aesthetically pleasing finish in keeping with the heritage of the structure. Importantly all works were completed well within a single working day.
