Induction apparatus for heat treatment of LONG concrete structures such as bored piles installed in the frozen ground

摘要

The invention relates to construction, namely, to the production of concrete and reinforced concrete piles in the wells drilled with the casing to form the foundation of various structures, preferably in permafrost and seasonally-frozen soil. In the manufacture of such piles in winter time or under conditions of deep soil freezing impossible to obtain a sufficiently strong pile without warming the solution and / or the surrounding soil.; The device uses induction heating advantages: unlimited duration of the heating easily controllable heat treatment, etc. mode To simplify the device consisting of a metal tube, humming on the casing that is installed in the well under the pile, and the windings of the copper bus disposed on the metal tube, the ends of which are connected to a power source, and to increase its reliability, therein the lower end of the bus is rigidly connected with the pipe to form an electrical contact, and a voltage source connected to the outer end of the bus and the electrical contact coupled to the outer end of the electrically conductive metal tube.; Use pipe being heatable body as a conductor for connection to a power source lower end of the bus further simplifies and improves the reliability of the induction heating in the construction of the frozen soil in the piles.
