The invention discloses an argillaceous cementing soft rock-soil body high-energy gas fracturing grouting method. A plurality of grouting holes are drilled around the position where a shaft is about to be drilled in the peripheral direction, and all the grouting holes form a grouting ring and are drilled to the hole termination depth; perforation work is conducted on all the grouting holes in a selected level height of the same height, and a plurality of perforated holes are formed in the level height; the depth of the perforated holes is 1/3 to 1/2 the diameter of the grouting ring formed by the grouting holes; any two adjacent grouting holes are selected, and a high-energy gas generation device is placed in the level height where the perforation work is conducted; acid liquid is injected, and the high-energy gas generation device is soaked in the acid liquid; the surface of the acid liquid is provided with an insulated plug; after high-energy gas fracturing balls in the high-energy gas fracturing device are triggered, water-glass-based composite slurry is injected into the two grouting holes; the steps are repeated till the grouting work of all the grouting holes in the same segment height is finished; upward grouting is adopted, and the steps are repeated till the grouting work of all the grouting holes is finished.
