A construction method for soft soil foundations in high-altitude and cold regions, using the construction device for soft soil foundations in high-altitude and cold regions as described in claim 6, characterized in that, Includes the following steps: Material mixing and processing: Place the material to be processed and the mixture in the inner cavity of the reinforcement material processing tank (1), separate and disassemble the hose (419) and the connecting pipe (416), insert the injection mechanism (4) into the inner cavity of the reinforcement material processing tank (1), place the caster wheel (54) above the pad (7), extend the bottom section of the segmented independent control electric telescopic rod (45) by controlling the extension of the bottom section, drive the moving ring (43) to move downward, and push the first square tube (41) downward by the first spring (49), so that the two injection half tubes (40) rotate and separate, and extend the bottom section of the segmented independent control electric telescopic rod (45) by controlling the extension of the bottom section. The two injection half-pipes (40) are continuously separated and closed. The moving ring (43) is threadedly connected to the vertical pipe (42). When the moving ring (43) moves vertically, it drives the vertical pipe (42) to rotate synchronously. The vertical pipe (42) drives the first square pipe (41) and the injection half-pipe (40) to rotate, thereby stirring and processing the reinforcement material processing pool (1). By controlling the extension of the middle section of the segmented independent control electric telescopic rod (45), the circular plate (46), the first inclined plate (47) and the first square pipe (41) are driven to move vertically. The height of the first square pipe (41) is adjusted, thereby stirring and processing the materials at different depths in the reinforcement material processing pool (1). The material at different positions is stirred and processed: the electric push rod (50) is controlled to move the connecting block (51), the connecting block (51) moves the supporting vertical plate (53) through the second inclined plate (52), the supporting vertical plate (53) drives the third inclined plate (510), the movable sleeve (511), the drive rod (512) and the convex plate (523) to move. After the convex plate (523) contacts the toothed plate (6) it cannot move. The electric push rod (50) is controlled to retract, and the two supporting vertical plates (53) are pulled closer to each other through the second inclined plate (52). The supporting vertical plate (53) pushes the movable sleeve (511) to move upward through the third inclined plate (510). The movable sleeve (511) drives the spring telescopic rod (519) to move vertically. When the spring telescopic rod (519) moves upward in the inner cavity of the positive spiral groove (517), it squeezes the inner wall of the positive spiral groove (517). The drive rod (510) 2) Drive the convex plate (523) to rotate, and through the engagement of the convex plate (523) with the toothed plate (6), the drive rod (512) moves forward along the toothed plate (6), thereby driving the injection half-pipe (40) to move forward. Adjust the position of the injection half-pipe (40) to stir and process the material at different positions inside the reinforcement material processing pool (1). When the spring telescopic rod (519) moves downward in the inner cavity of the forward spiral groove (517), the inclined surface (520) contacts the inner wall of the forward spiral groove (517) and is squeezed, causing the spring telescopic rod (519) to contract away from the inner cavity of the forward spiral groove (517) and avoid the drive rod (512) from rotating in the opposite direction. Similarly, when the spring telescopic rod (519) moves vertically in the inner cavity of the reverse spiral groove (518), the drive rod (512) can move in the opposite direction along the support plate (417), driving the injection half-pipe (40) to move in the opposite direction to stir the material. Deep hole injection of foundation: Remove the injection mechanism (4) from the reinforcement material processing pool (1), close the two injection half pipes (40) by operation, align the bottom of the two injection half pipes (40) with the deep hole processed on the foundation, thread the hose (419) onto the surface of the connecting pipe (416), move the bottom section of the segmented independent control electric telescopic rod (45) upward by control, drive the moving ring (43) upward, so that the moving ring (43) squeezes the two irregular plates (412), so that the irregular plates (412) drive the sealing plate (411) to move laterally, so that the two sealing plates (411) separate, and transport the material by controlling the material conveying pump (2). The material in the inner cavity of the reinforcement material processing pool (1) passes through the suction pipe (3), the material conveying pump (2), the hose (419), the connecting pipe (416), the second square pipe (410), the vertical pipe (42) and the injection half pipe (40) in sequence, and finally inject the material into the deep hole; Strengthening and supporting the construction device: By controlling the electric push rod (50) to extend, the two supporting vertical plates (53) are pushed away from each other by the second inclined plate (52). The supporting vertical plates (53) drive the movable sleeve (511) to move downward through the third inclined plate (510). The movable sleeve (511) drives the convex plate (523) and the drive rod (512) to move downward, so that the drive rod (512) is inserted into the soil to support the construction device. Rotating the knob drives the threaded rod (514) to rotate, so that the threaded rod (514) moves upward. The threaded rod (514) pushes one side of the expansion block (516) to move through the connecting rod (515), so that one side of the expansion block (516) extends out of the drive rod (512) and enters the soil to strengthen the drive rod (512). Smoothing the top of the material: After the deep hole cavity is filled with material, the two injection half tubes (40) are rotated to a horizontal state by operation. The moving ring (43) is controlled to move downward, and the threaded drive of the vertical tube (42), the second square tube (410) and the injection half tube (40) are rotated. By controlling the extension of the middle section of the segmented independent control electric telescopic rod (45), the two rotating injection half tubes (40) come into contact with the top of the reinforcing material, and the top of the reinforcing material is smoothed.
