Soil remediation agent adding device

The soil remediation agent adding device comprises a fixing mechanism and a geomembrane, the fixing mechanism comprises a vertical rod and a lower baffle connected to the lower portion of the vertical rod, a chemical injection hole is formed in the top of the vertical rod, an inner cavity is formed in the vertical rod, chemical seepage holes are formed in the side face of the vertical rod, the chemical seepage holes are communicated with the inner cavity, and the geomembrane is arranged in the inner cavity. The bottom of the lower baffle is connected with a fixing head through an inserting rod, the multiple fixing mechanisms are arranged, and the geomembrane wraps the outer sides of the multiple fixing mechanisms. And then the flexible HDPE geomembrane is wound on the vertical rods of the multiple fixing mechanisms, so that the flexible HDPE geomembrane is distributed around the polluted soil by multiple circles, and therefore a vertical barrier for managing and controlling the risk of the polluted site is fo
