#CMT# #/CMT# The equipment has a soil treating tool (10) comprising a main injection nozzle (20) for injecting pressurized fluid in the soil and mounted on a lower end of a rotative tubular core (12). Fluid sucking units having a suction pipeline and vacuum pumping units (36), are arranged in an upper part of a bore, and sealing units constituted of pivoting shutters and elastic bellows sealed on an upper part of the bore in which the pressurized fluid rises through boring area surrounding the core, and is destructably maintained by soil agitation units (28, 30). #CMT# : #/CMT# An independent claim is also included for a method for treating pollutant in soil. #CMT#USE : #/CMT# Equipment for treating pollutant in soil to rehabilitation of the soil contained in the ground water. #CMT#ADVANTAGE : #/CMT# The sealing units seal the upper part of the bore in which the pressurized fluid rises through the boring area surrounding the tubular core, and is destructably maintained by the soil agitation units, thus allowing treatment of pollutants in the soil to allow better definition of the treatment area in an effective manner, and hence ensuring better reliability in the recovery of volatile pollutants and preventing the pollutants extracted from the soil falling into the atmosphere. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a vertical sectional view of an assembly of an equipment for treating pollutant in soil during operation. 10 : Soil treating tool 12 : Rotative tubular core 20 : Main injection nozzle 28, 30 : Soil agitation units 36 : Vacuum pumping units. |
