TUNNEL CONSTRUCTION IN ARTIFICIALLY FROZEN SOIL

TUNNELBYGGNAD I FRYST JORD

This is a description of a tunnel construction project in Gothenberg, Sweden, especially two parts of the tunnel, driven through soil. The freezing of the soil, a sandy silt and a till were performed by means of evaporation of freon gas in steel pipes surrounding the tunnel tube. The pipes had the same strength as the respective part of the tunnel and were installed parallel to the tunnel tube in a circle, 700 mm outside the tube. Thus a layer of frozen soil about 1 m. thick, surrounded the tunnel tube. /TRRL/
