METHOD AND APPARATUS FOR CLEANING POLLUTED GROUND OR WASTE LANDFILL GROUND

摘要

PROBLEM TO BE SOLVED: To enhance the cleaning capacity of the polluted ground to a large extent by intermittently injecting a cleaning accelerating component in the polluted ground (including even waste landfill ground) at a short-time interval in a pulse-like manner under ultrahigh pressure to explosively blow the same in the polluted ground to allow the cleaning accelerating component to reach over a remoter and wider range. SOLUTION: A cleaning accelerating component is intermittently supplied to the injection well 14 inserted in the polluted ground 12 under ultrahigh pressure at a short-time interval in a pulse-like manner and injected in the polluted ground 12 from the jet orifices 14a of the injection well 14 under ultrahigh pressure in predetermined intermittent timing. By this constitution, the cleaning accelerating component is explosively blown in the polluted ground 12 by labyrinth effect to be allowed to reach over a remoter and wider range.
