when the servo motor (31) drives the soil remediation inserted bar (2) to vertically move downwards to be inserted into soil, air prestored into the air storage tank (53) through the air compressor (51) enters the soil remediation inserted bar (2) through the air supply pipeline (50), and then the air in the soil remediation inserted bar (2) is exposed out of the exhaust holes (20), so that the soil is prevented from entering the soil remediation inserted bar (2) through the exhaust holes (20) and blocking the exhaust holes (20) by the soil;
when all the exhaust holes (20) on the soil restoration inserted bar (2) are immersed into the soil, the servo motor (31) and the air release valve (54) are closed, and the installation operation is completed;
b) the method comprises the following steps Soil restoration operation, in particular to ozone emission into soil through a soil restoration inserted bar (2)
Ozone prepared by an ozone generator (41) is prestored in an ozone storage tank (43), an ozone release valve (44) is opened, the ozone in the ozone storage tank (43) enters the soil remediation inserted bar (2) through an air supply pipeline (50), and then the ozone in the soil remediation inserted bar (2) is discharged into soil through each exhaust hole (20), so that the soil is treated and remedied;
c) the method comprises the following steps Disassembling, in particular to pull out the soil repairing inserted bar (2) from the soil
Closing the ozone release valve (44), stopping soil remediation, starting the servo motor (31) and the blower (61), opening the air release valve (54), and changing the steering direction of the servo motor (31);
the servo motor (31) drives the soil remediation inserted bar (2) to vertically move upwards and gradually pull out from soil, air prestored in the air storage tank (53) through the air compressor (51) enters the soil remediation inserted bar (2) through the air supply pipeline (50), and then the air in the soil remediation inserted bar (2) is exposed out of each exhaust hole (20), so that the soil is prevented from entering the soil remediation inserted bar (2) through the exhaust holes (20) and blocking the exhaust holes (20) by the soil;
the servo motor (31) drives the cylindrical brush (65) to axially rotate, meanwhile, air blown into the air distribution ring body (62) through the air blower (61) is vertically blown downwards into the cylindrical brush (65) through the air outlet holes (640), bristles (652) of the cylindrical brush (65) are combined with the air blown into the cylindrical brush (65) to blow the outer side of the soil remediation inserted rod (2), and therefore soil particles bonded in the process that the soil remediation inserted rod (2) is pulled out of soil are removed;
when the soil restoration inserted bar (2) is completely pulled out of the soil, the servo motor (31) and the air blower (61) are closed, the air release valve is closed, and the disassembly operation is completed.
10. A method of using a soil remediation system according to claim 9, wherein: the disassembly operation is carried out when the soil restoration inserted rod (2) is repaired or maintained or the inserted position of the soil is changed.
