[0048] First, by covering the soil to be repaired with the tape 4 and delivering the liquid medicine in a drip irrigation manner, it is possible to ensure uniform spraying of the liquid medicine while preventing the liquid medicine from volatilizing and being inhaled by the workers. At the same time, since the tape 4 covers the soil, it has the function of locking water in high temperature scenes, thereby improving the effect of soil repair;

[0049] Second, it is easy to use; the present application can complete the soil remediation operation by one person. The staff holds the end of the tape 4 and moves it to cover the soil to be remediated with the tape 4. After the tape 4 is drawn to a predetermined length, the iron sheet 20 triggers the induction switch 14, the liquid medicine barrel 2 automatically moves down, and the quick-connect male connector 9 is inserted into the quick-connect female connector 7 to deliver the liquid;

[0050] Third, accurate liquid delivery is achieved; by providing the sealing film 77, the liquid medicine is only delivered to the side from which it is drawn out, and does not flow to the other side, so that the problem of liquid medicine leakage will not occur;

[0051] Fourthly, by inserting the quick-connect male connector 9 into the quick-connect female connector 7, the hard liquid conduit 8 is connected to the drip irrigation chamber 5, and the withdrawn state of the tape 4 is locked to prevent the tape 4 from being rolled up under the action of the elastic winding component;

[0052] Fifth, it has strong applicability; the present application can change the withdrawal length of the roll 4 according to the area of ​​the soil to be repaired, thereby meeting the use scenarios of different areas.

[0053] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
