...T.G. Newman; H.-Y. Wong Abstract Abstract A tunnel extension to the Thames Water Ring Main has recently been completed in SE London. Two new deep shafts were built at either end, using jacked caisson construction methods. One of the shafts was excavated through much of the London Basin Palaeogene...

...T. Newman Abstract Abstract The Thames Water Ring Main has been driven through the various Palaeogene deposits of London and the underlying Cretaceous Chalk. Much of the tunnel alignment was designed to keep within the London Clay Formation over the western half of the project, although discovery...
