Dual packer system for soil remediation that can be selectively installed in contaminated depths and sprayed with a purifier

摘要

The present invention relates to a packer device that is inserted into a perforated hole formed through an unsaturated layer in the ground to a saturated layer and sprays a fluid supplied from an injection device to purify contaminants in the ground. By spraying pressurized water or air supplied from the injection device toward the saturation layer, a contaminant rise induction part for floating contaminants in the saturation layer, and a hollow tube inserted in the perforation hole parallel to the contaminant rise induction part. , A purifying agent injection unit for purifying contaminants by spraying the purifying agent supplied from the injection device to the unsaturated layer through a purifying agent injection port, and sealing the upper and lower portions of the perforation hole around the purifying agent injection port to partition the injection section of the purifying agent. It characterized in that it comprises a sealing means, and a connection casing that can be connected to the upper portion of the sealing means in multiple stages to adjust the insertion length according to the depth of the perforated hole.
