Description: | Sinking the bridge piers amidst the Severn's 40ft spring tides was an immense undertaking for the Victorian builders. To affix the 10ft diameter cast iron piers into the bedrock, the assembly was pressurised by steam compressor and the footing excavated by men working inside the piers to a depth of 4 ft below bedrock. The piers were then weighted, lowered into place and backfilled with concrete. Locals recall workers emerging from the pressure bell with blood streaming from their ears and noses. | Subjects: | Transport (Rail) Aerial View Railway Bridge | Source: | English Heritage - Viewfinder | Creator: | Wingham, H A | Identifier: | http://viewfinder.english-heritage.org.u... | Language: | en | Go to resource |
