Some applications of a successful chemical injection process to tube railway construction work in London are described. The extension of the Central Line tube railway between Bow and Leyton was carried out in water-logged ground by means of compressed air. At Leyton station the lines are carried from the tunnels to the surface in an open cut. On approaching this open cut the two shields of the 12-ft. running tunnels were carried through with a cover of only 4-5 ft. of ballast, with water level almost at the surface. The method of foundation strengthening is discussed and the tunnel network and track foundation is illustrated in drawings and photography.
