Embodiment 1

[0034] Embodiment one: a kind of soil remediation device, such as figure 1 As shown, it includes a repair sleeve 1 inserted into the soil and a liquid injection mechanism 2 for injecting soil repair liquid into the repair sleeve 1. The top of the repair sleeve 1 is provided with a sensor 9 for sensing whether it is flush with the soil surface. The sensor 9 adopts an infrared sensor 9, and the sensor 9 is connected with a controller 10, which is arranged on the top of the repair sleeve 1, so as to sense whether the repair sleeve 1 is plugged in place, thereby stopping the insertion and performing corresponding repair operations.

[0035] like figure 1 As shown, the liquid injection mechanism 2 uses a liquid injection nozzle to inject into the soil in the repair sleeve 1. The repair sleeve 1 is connected to a drain pipe 3, and the drain pipe 3 is connected to a liquid suction pump 4. The liquid suction pump 4 is far away from the One end of the liquid discharge pipe 3 is connec...

Embodiment 2

[0041] Embodiment 2. The difference between this embodiment and Embodiment 1 is that a method for soil restoration is provided, which is characterized in that the soil restoration device in Embodiment 1 is used for restoration, including the following steps:

[0042] S1. Insert the repair sleeve 1 into the soil to be repaired, and rotate the repair sleeve 1 following the direction of the screw knife 12, and start the soil breaking mechanism 13 at the same time, so that the repair sleeve 1 is gradually inserted into the soil;

[0043] S2. When the repair sleeve 1 is inserted until its top is flush with the soil, the signal from the sensor 9 is fed back to the controller 10, and the controller 10 controls the drive mechanism 8 to start;

[0044] S3, the driving mechanism 8 drives the folding cover 6 to unfold from the installation box 7, so as to seal the bottom of the repair sleeve 1;

[0045] S4. Inject the soil remediation solution into the repair sleeve 1 through the liquid ...

Abstract

The invention discloses a soil remediation device, and relates to the technical field of soil remediation. The device comprises a remediation sleeve inserted into soil and a liquid injection mechanism, the repairing sleeve is connected with a liquid discharging pipe, the liquid discharging pipe is connected with a liquid extracting pump, one end of the liquid extracting pump is connected with a purification mechanism, the remediation sleeve comprises an insertion cylinder, a spiral cutter arranged on the outer wall of the insertion cylinder in a threaded mode and a soil breaking mechanism arranged at the bottom of the insertion cylinder, a guide groove is formed in the side wall, located above the ground breaking mechanism, of the bottom of the inserting cylinder, a folding cover is arranged on the guide groove in a sliding mode, a mounting box is arranged on the outer wall of the bottom of the inserting cylinder, and a driving mechanism used for driving the folding cover to be unfolded or folded and stored in the mounting box is arranged in the mounting box. The soil remediation device can conveniently and quickly enter soil, can seal the soil to perform efficient remediation, facilitates harmful substance separation, and has the advantage of improving the soil remediation effect.

Description

technical field [0001] The invention relates to the technical field of soil restoration, more specifically, it relates to a soil restoration device and a restoration method thereof. Background technique [0002] The discharge of industrial sewage, oil spills, pesticides and the abuse of various chemical fertilizers have caused soil pollution. Soil pollution not only affects crops, but also seriously damages the ecological environment, requiring soil restoration. [0003] The remediation of existing polluted soil generally refers to the use of physical, chemical and biological methods to transfer, absorb, degrade or transform pollutants in the soil to reduce the concentration of pollutants to a harmless level, or to convert harmful pollutants into harmless substance. However, in the existing soil remediation technology, the efficiency of separating pollutants from the soil is generally low, the effect on soil remediation is not ideal, and it is not easy to operate. Conten...
