Soil remediation system and soil remediation method

Abstract

The invention discloses a soil remediation system and a soil remediation method. The soil remediation system comprises a heating unit; the injection and extraction unit comprises an injection unit and an extraction unit, the injection unit comprises a plurality of injection well pipes, the injection well pipes comprise a plurality of injection hard well pipes and a plurality of injection soft well pipes, and the injection hard well pipes are connected to the injection soft well pipes; the extraction unit comprises a plurality of extraction well pipes, the extraction well pipes comprise a plurality of extraction hard well pipes and a plurality of extraction soft well pipes, and the extraction hard well pipes are connected to the extraction soft well pipes; and a processing unit. Due to the fact that the injection soft well pipe and the extraction soft well pipe can be adjusted in a deformation mode, the pipe drawing construction curvature radius of the well pipe can be reduced, the construction acting face can be reduced, the drill hole linear meter number can be reduced, well pipe consumables can be reduced, and cost can be reduced. And the device can adapt to a soil-entering arc-shaped channel and a soil-discharging arc-shaped channel required when the drilling machine is arranged on the earth surface, and the drilling machine does not need to be arranged in soil, so that construction procedures are reduced.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration system and a soil restoration method. Background technique [0002] The soil is originally a natural shelter and purification treatment site for various wastes. When the soil contains too many pollutants, which affects or exceeds the self-purification ability of the soil, the soil itself also needs to be repaired. [0003] The prior art discloses a soil remediation system, which includes a heating device, a horizontal well pipe, a vertical well pipe and an exhaust gas treatment device. The horizontal well pipe is connected to the vertical well pipe, and the two horizontal well pipes and the two vertical well pipes are respectively Constitute the heating well pipe and the extraction well pipe, the tail gas treatment device is connected with the extraction well pipe, the heating device heats and heats the soil through the heating well pipe, and extracts ...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the prior art that the drilling rig needs to be located in the soil and be constructed in the soil to lay the pipes, so that the soil needs to be constructed before the pipes are laid to meet the construction requirements of the drilling rig, thereby increasing It eliminates the construction process, and the defects of large curvature radius of well pipe drawing construction, many well pipe consumables, and high cost, thereby providing a soil remediation system and soil remediation method
