step 2: when the movable ring is placed to the required depth, air pressure is injected into the end part through a drill rod, the top cap (202) is pushed by the air pressure, the push rod (203) is pushed by the top cap (202) to drive the movable ring (213) to compress the spring, the top cap (202) is pressed to punch through the bulge on the inner wall of the cap body to form limit clamping, the guide sliding pin (210) of the movable ring (213) pair moves to the other end of the sliding groove, and the outer soil layer (1) is communicated with the inner target (211) through the sliding groove;
step 3: the method comprises the steps of collecting alloy elements, forming electrochemical reaction with heavy metal in a soil layer (1) through active materials on a target (211) in the soil layer (1), and enabling water in the soil layer (1) to promote electrochemical progress to replace heavy metal ions on the target (211) to form collection;
step 4: measuring feedback, emitting X-rays through an X-ray light source (2019), striking the X-rays on a target (211), reflecting the X-rays through the target (211), performing light splitting through a light splitting crystal plate (2014) to form different spectrum rays, correspondingly reflecting the different spectrum rays onto a detector (2015), and performing data feedback analysis through the detector (2015) to obtain corresponding spectrums;
step 5: and (3) data summarizing and analyzing, namely feeding the data detected by the inner detection ring (201) back to the data platform through the wireless transceiver to form a collating and summarizing, and detecting and analyzing the heavy metal condition of the deep soil body.
