Disclosed is a method for using a dual-rectangular combined stirring drilling machine. First cutters and second cutters on a first rectangular cutting frame cut and stir a soil layer outside a first stirring cutting head at the lower end of a first stirring shaft and inside the first rectangular cutting frame into slurry during movement. First cutters and second cutters on a second rectangular cutting frame cut and stir a soil layer outside a first stirring cutting head at the lower end of a fourth stirring shaft and inside the second rectangular cutting frame into slurry during movement. First cutters and second cutters on two first stirring arms cut and stir a soil layer outside a second stirring cutting head at the lower end of a second stirring shaft and inside the two first stirring arms into slurry during movement. First cutters and second cutters on two second stirring arms cut and stir a soil layer outside a stirring cutting head at the lower end of a third stirring shaft and inside the two second stirring arms into slurry during movement. The slurry flows out of holes. A main drill rod forms a dual-rectangular combined hole body in the downward-pushing process.
