An application method for a rectangular stirring drilling machine is provided. During work of the rectangular stirring drilling machine, a drilling rod (A), a drilling rod (B), a drilling rod (G) and a drilling rod (H) individually drive the corresponding drilling bits to synchronously rotate in a clockwise direction; a drilling rod (C), a drilling rod (D), a drilling rod (E) and a drilling rod (F) individually drive the corresponding drilling bits to synchronously rotate in a counterclockwise direction; high pressure water is injected; soil of areas covering the eight drilling bits is cut by the eight drilling bits and mixed with water to form mud; eight eccentric bodies on lower parts of the eight drilling rods are driven by the same to rotate, so a rectangular cutter (A), a rectangular cutter (A), a rectangular cutter (B), a rectangular cutter (C), a rectangular cutter (D) are driven in pairs to rotate in opposite directions; soil of areas uncovering the eight drilling bits is cut by a plurality of reamers on the lower parts of the four rectangular cutters and is mixed with water to form mud; and mud flows out to form rectangular holes.
