JAPAN LINES UP NEW TUNNELLING TECHNIQUE

A shallow-tunnelling and shaft sinking technique developed in Japan by Nishimatsu Construction, and already used in the UK, is suggested as an economic alternative to ground freezing in certain applicaitons. The technique employs steel tubes linked to form a watertight barrier in a similar manner to sheet piling. The tubes can be positioned either vertically or horizontally. The technique of forming vertical or horizontal cofferdams using the interlocking tubes is thought likely to find application in large excavations where difficult ground conditions are found in urban areas. /TRRL/
