Allowing for the Water Permeability of Frozen Ground Screens during their Formation (Ob Uchete Vodopronitaayemosti Ledogruntovykh zaves v Protsesse ikh Vozvedeniya),
Abstract
Creation of water-impermeable cofferdams in an important and sometimes extremely complex problem which builders, in particular those who construct hydraulic facilities, are frequently called upon to solve. One of the most widely used methods of constructing water-impermeable dams is the method of artificially freezing ground which, as is known, consists of the following: Freezing columns are implanted in the dam with a certain distance between them. Brine is circulated in the columns, and is cooled by a refrigeration device. Initially individual frozen ground cylinders are formed around each column, and these cylinders then join into a single water-impermeable mass.
