Abstract
Система замораживания грунтов, содержащая скважины, пробуренные эквидистантно по контуру выработки или котлована, в скважины опущены замораживающие колонки, а в них - питающие трубы, в колонках циркулирует охлажденный на замораживающей станции рассол, коллекторы, соединяющие выход замораживающих колонок с замораживающей станцией, в качестве рассола используется раствор соли хлористого кальция, рассол охлаждается на замораживающих станциях холодильными машинами, отличающаяся тем, что замораживающие колонки выполнены из титано-никелевого сплава с эффектом памяти формы, замораживающие колонки первоначально имеют трубчатую цилиндрическую форму с продольным гофрированием, сплаву замораживающих колонок задано фазовое превращение при критической температуре в цилиндрическую форму.A soil freezing system containing wells drilled equidistant along the output or pit contour, freezing columns are lowered into the wells, and supply pipes are placed in them, brine cooled at the freezing station is circulated in the columns, collectors connecting the output of the freezing columns to the freezing station as a brine a salt solution of calcium chloride is used, the brine is cooled at freezing stations by refrigeration machines, characterized in that the freezing columns are made of titanium-nickel of a shape memory effect alloy, freezing columns initially have a tubular cylindrical shape with longitudinal corrugation, a phase transformation at a critical temperature into a cylindrical shape is specified for the freezing column alloy.
