The invention discloses an implementation method for a trapezoid composite soil pile machine. When the trapezoid composite soil pile machine works, a hydraulic motor drives a second drill rod to rotate, when the second drill rod rotates, a drill bit is driven to rotate, and when the drill bit rotates, multiple cutter teeth on the lower portion of the drill bit cut up and stir a soil body; high-pressure water is entered from the upper end of a first drill rod into the drill bit through the second drill rod, the high-pressure water is ejected from multiple injected holes in the lower portion of the drill bit, and the cutter teeth on the lower portion of the drill bit stir the soil and the water into slurry; a control device controls a first oil jack and a second oil jack to perform reciprocating action synchronously, therefore, a trapezoid frame is driven to vertically move back and forth, and the cutter teeth on the trapezoid frame and the lower portion of the trapezoid frame and transverse cutters inside the trapezoid frame cut the soil body failing to be cut in the trapezoid frame, and the soil and the high-pressure water overflowed from the injected holes are stirred into slurry; the slurry flows to the outside through trapezoid holes, and the trapezoid holes are formed in the process when the first drill rod presses and goes downward.
