The locking seat 710 is loosened and resets upward by the tension spring, so that the sealing block 712 is embedded in the soil layer.

[0022] In this embodiment, Figure 12 、 Figure 13 、 Figure 14 and Figure 15 As shown, a first trigger cavity 12 is provided in the inner wall of the trigger box 11, and a sliding groove 13 is provided on the inner wall of the first trigger cavity 12. A triangular plate 14 is slidably connected to the inner wall of the sliding groove 13. The outer wall of the triangular plate 14 is slidably connected to the inner wall of the sliding groove 13. One end of the triangular plate 14 is fixedly connected to a pressing plate 15, and the bottom end of the pressing plate 15 is fixedly connected to a plug rod 16, and a return spring is sleeved on the outer wall of the plug rod 16.

The lower pressure block 17 will push the push plate to one side. Since the push plate is slidably set on the bottom push block 6, the push plate slides, and since the inner arc piece 8 is engaged with the gear column 1019, when the inner arc piece 8 and the push plate move together, the inner arc piece 8 drives the gear 1014 column to rotate.

[0023] In this embodiment, Figure 5 、 Figure 6 、 Figure 7 and Figure 14 As shown, the pressing mechanism 10 includes an upper slide 1001 of a glyph structure, one end of the upper slide 1001 is inserted into the inner wall of the second trigger cavity 18, and the top of the upper slide 1001 is in contact with the inclined surface of the triangular plate 14, a sliding cavity 1002 is provided in the inner wall of the upper slide 1001, and an inclined groove 1003 is provided in the inner wall of the sliding cavity 1002, a lower pressure rod 1004 is slidably connected to the inner wall of the sliding cavity 1002, and telescopic spring rods 1005 are fixedly connected to both sides of the top of the lower pressure rod 1004, and the telescopic spring rod 1005 is slidably connected to the inclined groove 1003; The bottom end of the lower pressure rod 1004 is hinged with a telescopic lever 1006, and the telescopic lever 1006 is rotatably connected to the inner wall of the metal box 2, and the other end of the telescopic lever 1006 is hinged with a sealing column 1007, and the bottom end of the sealing column 1007 is inserted into the inside of the squeeze-in cavity 78. Then, after the pressing plate 15 moves down a distance, the triangular plate 14 on the side wall of the pressing plate 15 squeezes and pushes the upper slide 1001. Since the inner wall of the sliding cavity 1002 is provided with an inclined groove 1003, the inner wall of the sliding cavity 1002 is slidably connected with the lower pressure rod 1004, so that the upper slide 1001 During sliding, the upper sliding plate moves through the inclined groove to pull the lower pressure rod 1004, and the lower pressure rod 1004 rises to drive the telescopic lever 1006. The other end of the telescopic lever 1006 pushes the sealing column 1007 downward, and the sealing column 1007 moves downward to press the mud squeezed into the cavity 78 into the injection cavity 79. The mud in the injection cavity 79 pushes the sealing block 712 upward, so that the sealing block 712 is completely inserted into the soil layer, and the excess mud will flow into the soil layer, so that the extrusion sheet 77 is mixed with the soil layer through the mud, and the extrusion sheet 77 can be completely solidified in the soil layer after the mud solidifies.

[0024] In this embodiment, Figure 16 and Figure 17 As shown, the pressing mechanism 10 also includes a frame 1008, which is fixed on the top wall of the through window 9, and a slider 1009 is slidably connected to the inner wall of the frame 1008, and the bottom end of the slider 1009 is rotatably connected to the closing door 1010, and a sliding groove 1011 is provided on the side wall of the closing door 1010, and an L-shaped connecting plate 1012 is slidably connected to the inner wall of the sliding groove 1011, and one end of the connecting plate 1012 is fixedly connected to a rotating rod 1013, and the rotating rod 1013 is rotatably connected to the bottom end of the sliding groove 1011. The top end is fixedly connected to a toggle gear 1014, a rotating sleeve 1015 is sleeved on the outer wall of the rotating rod 1013, and the rotating sleeve 1015 is fixedly connected to the frame 1008. A sliding sleeve 1016 is fixedly connected to the side wall of the rotating sleeve 1015, and a toothed plate 1017 is slidably connected to the inner wall of the sliding sleeve 1016. The toothed plate 1017 is engaged with the toggle gear 1014, and a sleeve 1018 is inserted at the front end of the toothed plate 1017. The end of the sleeve 1018 is hinged to the side wall of the frame 1008. The bottom end of the rotating rod 1013 is fixedly connected to a gear column 1019, and the outer wall of the gear column 1019 is meshed with the inner wall of the inner arc piece 8. When the inner arc piece 8 and the push plate move together, the inner arc piece 8 drives the gear 1014 column to rotate, and the gear column 1019 drives the rotating rod 1013 to rotate. The connecting plate 1012 and the toggle gear 1014 on the rotating rod 1013 rotate, and the toggle gear 1014 pushes the tooth plate 1017 to move to one side, so that the tooth plate 1017 and the sleeve 1018 are expanded, and at the same time, the connecting plate 1012 on the rotating rod 1013 will pull the closing door 1010 from a vertical state to a horizontal rotation, so that the closing door 1010 will cover the through window 9, and at the same time, when the closing door 1010 is closed, the mud can be pushed into part of the through window 9.

[0025] In this embodiment, Figure 9 As shown, the front end of the pressing piece 716 has an inclined surface formed by machining, and the pressing piece 716 is slidably connected to the L-shaped rod 715, so that when the pressing piece 716 is squeezed by the soil layer, the pressing piece 716 can push the L-shaped rod 715 downward.

[0026] The use method and advantages of the present invention: The working process of the high-stability road pile foundation is as follows: like Figures 1 to 17 As shown, before installing the pile foundation, the staff needs to use a drilling rig to drill the pile foundation hole at the marked point and pump mud into it to mix with the mud layer. At this time, the pile foundation is hoisted and placed along the pile foundation hole, accompanied by the pile basic body 1 gradually descending until the bottom end of the pile basic body 1 contacts the bottom end of the pile foundation hole, and is pressed down by the gravity of the pile basic body 1 itself. At this time, the bottom pushing block 6 in the metal box 2 is pressed and moved upward, and the bottom pushing block 6 pushes the pushing block 5 upward, and the pushing block 5 pushes the pushing column 73 up, pushing the convex point on the outer wall of the pushing column 73 to move in the spiral groove 72, pushing the bearing column 71 to rotate, and the bearing column 71 drives the bearing plate 74 to rotate. At this time, the convex block 75 on the bearing plate 74 rotates, squeezing and pushing the V-shaped plate 76 to slide to one side, and one side of the V-shaped plate 76 slides and pulls the extrusion sheet 77, causing the extrusion sheet 77 to rotate, and the end of the extrusion sheet 77 is embedded in the soil layer until the front end is inserted into the soil layer; When the extrusion piece 77 is inserted into the soil layer, the pressing piece 716 on the side wall of the extrusion piece 77 is blocked and squeezed by the soil layer, so that the extrusion piece 77 pushes the L-shaped rod 715 downward, and the L-shaped rod 715 pushes the wedge block 714, which is retracted into the locking seat 710. The locking seat 710 is loosened and returns to move upward by the tension spring, so that the sealing block 712 is embedded in the soil layer. Then, as the second piece of wavy pile foundation is inserted, the trigger block 3 on the side wall of the metal box 2 first contacts the pressing plate 15, and the pressing plate 15 pushes the lower pressing block 17 downward through the plug-in rod 16. The lower pressing block 17 will push the top push plate to one side. Since the top push plate is slidingly set on the bottom push block 6, the top push plate slides, and since the inner arc piece 8 is engaged with the gear column 1019, when the inner arc piece 8 and the top push plate move together, the inner arc piece 8 drives the gear column 1014 to rotate, and the gear column 1019 drives the gear column 1019 to rotate. The rotating rod 1013 rotates, and the connecting plate 1012 and the toggle gear 1014 on the rotating rod 1013 rotate. The toggle gear 1014 pushes the tooth plate 1017 to move to one side, so that the tooth plate 1017 and the sleeve 1018 are expanded. At the same time, the connecting plate 1012 on the rotating rod 1013 pulls the closing door 1010 from a vertical state to a horizontal state, so that the closing door 1010 will cover the through window 9. At the same time, when the closing door 1010 is closed, the mud can be pushed into the through window 9. Then, after the pressing plate 15 moves down a distance, the triangular plate 14 on the side wall of the pressing plate 15 will squeeze and push the upper slide plate 1001. Since an inclined groove 1003 is provided in the inner wall of the sliding cavity 1002, a lower pressure rod 1004 is slidably connected to the inner wall of the sliding cavity 1002. When the upper slide plate 1001 slides, the upper sliding plate moves through the inclined groove to pull the lower pressure rod 1004. The lower pressure rod 1004 rises to drive the telescopic lever 1006. The other end of the telescopic lever 1006 pushes the sealing column 1007 downward. The sealing column 1007 moves downward to press the mud squeezed into the cavity 78 into the injection cavity 79. The mud in the injection cavity 79 pushes the sealing block 712 upward, so that the sealing block 712 is completely inserted into the soil layer, and the excess mud will flow into the soil layer, so that the extrusion sheet 77 is mixed with the soil layer through the mud, and the extrusion sheet 77 can be completely solidified in the soil layer after the mud solidifies.

[0027] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions of the technical solution of the present invention by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present invention.
