<p>PURPOSE:To reduce running costs by converting sunshine to heat and executing heating of contaminated soil in a method for repairing the contaminated soil by heating the inside of the soil. CONSTITUTION:Pipes 11 for piping which transport a heat medium (mainly contg. water) are installed on the soil to be repaired in the case of repair of the soil contaminated by hydrocarbons, such as arom. hydrocarbons, paraffinic and naphthenic or org. chlorine compds., such as trichloroethylene, tetrachloroethylene and tetrachloroethylene. This device is provided with a mirror 12 for light condensing designed to gather the solar heat into the pipes 11 for piping. The warm water warmed up by the solar heat in such a manner is sent by a pump 13 to the aquifer in the deep part of the soil. Further, the water in the aquifer of the deep part of the soil is ladled up by the pump 15 and is passed in the pipes 11 for piping so as to be heated by the mirrors 12 for light condensing. A vacuum pump 14 for extraction is installed in the aquifer so that the penetration of the hot water into the aquifer is effectively executed.</p> |
