Method for at least reduction of amount of contamination sources of soil and underground water with heavy metals

摘要

The present method at least reduce the amount of source of contamination of soil and groundwater contamination by heavy metals in the soil and from seeking to remove malfunctioning cable with lead sheath, preferably a source of drinking water in water reservoirs and rivers. Portions of the failing cable with lead sheath firmly anchored in the soil is released preferentially and simultaneously, before, or after, with over one of the free ends of the cable is removed soil to the free end is freely accessible from the Earth's surface. Then the freely accessible part of the cable creates a force that is greater than the friction force between the failing cable with lead sheath and soil, and lower than the ultimate tensile strength of the cable. Preferably against the action of a pulling force on freely accessible parts of the malfunctioning in the soil lying loose cable with lead sheath, at least over a portion of the cable is removed soil (eg. The topsoil) and / or paved surfaces and destroyed at least part of the overlying overburden.
