| Description: | SIPRE Translation Summary: Methods used in Moscow, Russia for digging frozen ground are described, and their effectiveness as conditioned by soil composition and thickness of the frozen layer is discussed. Personal safety in the city and safe methods of underground construction limit the application of the simple and inexpensive method of blasting. Wedge-shaped strikers have been used successfully to break-up ground frozen to depths less than 0.7-0.8 m. Preliminary thawing of frozen ground has proved effective near the end of winter, when frost penetration reaches 1.5 m or more in Moscow. Square cuts to depths of 60-80 cm in ground frozen to 1.5 m were effectively used in the construction of the Volga-Don Canal. |
