<p>PURPOSE:To facilitate burying construction by conducting heat source through a pipe arranged in a sinking layer and thawing the frozen sinking layer. CONSTITUTION:The sinking layer 4 to be arranged at the bottom part of a digged groove 1 where the duct 7 is arranged is formed of a soft plastic mat 5 and frozen with freezing liquid simultaneously while impregnated with water, and the duct 7 and soil 9 are arranged on the frozen sinking layer 4. Then the frozen ice in the sinking layer 4 is thawed by a heat source through the pipe 3 arranged in the sinking layer 4 to reduce the volume of the sinking layer 4 and also compress the layer; and molten liquid is absorbed by the bottom part peripheral ground of the digged groove 1, so the duct 7 and deposited soil are put in the same breaking phenomenon as ground subsidence. Thus, the duct 7 is sunk and displaced simultaneously, so the whole sinking facilities are simplified.</p> |
