[0037] Then, the hydraulic mechanism 4 is controlled to drive the top seat 5 to move up with the top mold 17, and waste soil mixed with a curing agent is added into the bottom mold 16. The hydraulic mechanism 4 is controlled to drive the top seat 5 to move down with the top mold 17 to cooperate with the bottom mold 16 to press the pile body. During the pressing process, the air intake fan 10 and the exhaust fan 12 are started. The air intake fan 10 blows the outside air to the heat sink 6. The air flows smoothly through the flow-promoting holes 7 and contacts the heat sink 6 with a large area, taking away the heat transferred to the heat sink 6 during the pressing process, so as to avoid excessive temperatures of various components of the device.

[0038] When the hole is pressed for a period of time, the control Figure 5 The servo motor 20 drives the sealing plate 21, the sealing gasket 22 and the movable column 23 to rotate 180°, the movable column 23 rotates stably in the limiting hole 24, the top end of the transfer hole 27 rotates to align with the bottom end of the outlet hole 28, and the evaporated free water accumulated in the top mold 17 is discharged through the exhaust micropores 26, the air collecting holes 25, the transfer holes 27 and the outlet holes 28 in sequence to avoid the accumulation of evaporated free water in the mold, and at the same time, the pressure is released to ensure the normal pressing and the structural strength of the pile body. This is the working principle of the mixed waste soil non-burning static pressing pile driver.
