The outer diameter of the piston 301 is adapted to the inner diameter of the pile pipe 1. The top end of the piston 301 is connected to the output end of the hydraulic cylinder 302.

Based on the scale mark 8, the material pump is activated to inject the cement mortar in the external storage tank into the pile pipe 1 through the first injection pipe 403 and the second injection pipe 405. The hydraulic cylinder 302 is activated again to drive the piston 301 rod to move the piston 301 downward, squeezing the cement mortar in the pile pipe 1 so that it is evenly squeezed out from the discharge hole 7 under pressure and seeps into the surrounding soil. At the same time, the pile pipe 1 is slowly lifted at a certain speed, and the hydraulic cylinder 302 follows synchronously and continuously pressurizes, so that the cement mortar is evenly discharged at different depths to form a uniform cement-soil pile. After the pile is completed, the device is moved to the next pile point.
