Soil gas explosion deep scarification device and method

The invention relates to the technical field of soil deep scarification, in particular to a soil gas explosion deep scarification device and method.The soil gas explosion deep scarification device comprises a supporting frame and an execution assembly, and the execution assembly comprises a rotating block, a mounting base, a driving block, a drilling rod, a moving block, a gas storage box, a deep scarification shovel, an air compressor and a connecting hose; the drilling rod is made to horizontally rotate along the center point of the mounting base, when the drilling rod is rotated to the position above soil needing deep scarification operation, the drilling rod is made to gradually move downwards, meanwhile, the drilling rod is driven to horizontally rotate along the axis of the drilling rod, and therefore drilling of the soil at different depths can be achieved; the drilling rod is firstly used for drilling the soil, and then the subsoiling shovel is used for subsoiling operation, so that the subsoiling sho
