The invention discloses a drip irrigation type automatic injection soil and underground water in-situ remediation agent injection technology and device. The technology comprises the steps that the balance time of the underground water level is measured; the potential energy of the remediation agent solution is utilized, and the remediation agent solution is automatically injected into to-be-remedied soil underground water through the injection well in a drip irrigation mode; drawing a water level burial depth and water level line equilibrium flow curve graph, determining a water level burial depth measurement result, and determining the water level line equilibrium flow of the medicament solution in each injection well, so that the underground water level line is kept stable; the soil and underground water to be remediated are sampled regularly, and related pollution factors are measured until the measured values of the pollution factors meet the remediation indexes. According to the remediation ...
