The specific implementation process is as follows:
the pile driving part is firstly made to slide upwards through a lifting rope 41 of the hoisting unit, and initially, the pile driving part slides upwards relative to the pile driving part 1, and after the top of the pile driving part abuts against a limiting block 11, the pile driving part 1 is driven to slide upwards, and at the moment, the punch 12 is positioned below the pile driving part. When the upper part of the lower end of the punching part 1 moves to the upper part of the soil, the pile driving part moves downwards by the winding unit, the punching part 1 moves downwards along with the pile driving part, and the punch 12 is positioned below the pile driving part, so that the punch 12 is firstly contacted with the soil, a hole is formed in the soil under the inertia effect of the punching part 1, and the soil around the hole is compacted by the punching part 1. Then the pile driving part moves downwards relative to the punching part 1, the pile driving part is firstly contacted with a supporting part formed at the upper end of the punching section 16, and the punching part 1 continues to move downwards for a certain distance under the inertia effect of the pile driving part, so that the depth of the formed hole is deepened.
Then make the portion of punching a pile and the portion of punching 1 upward movement through the hoist unit again, when the upper end of direction recess moved to with the slider relative position, start the pneumatic cylinder and can make the slider slide in the direction recess, make the portion of punching 1 anticlockwise rotation, the manual work lets in high-pressure gas in to high pressure channel 14 through high-pressure pipe 2 simultaneously, high-pressure gas makes connecting plate 31 upper end rotate to the one side of keeping away from the section of punching 16 after the effect is on connecting plate 31, vertical board 32 rolls out, promote soil to keeping away from section of punching 16 one side, improve the effect that compresses tightly to soil. When the high-pressure air upwards passes through the reinforcing part 4, the soil and the stones between the reinforcing part 4 and the punching part 1 can be blown out, and the situation that the stones damage the surface of the punching part 1 or the punching part 1 cannot rotate is avoided.
Until the height of the lower end of the punch 12 from the ground is greater than the height of the upper end of the reinforcement 4, then the reinforcement 4 is moved below the piling section and the reinforcement 4 is made coaxial with the punching section 16, the punching section 16 can be slid down a distance when positioning the reinforcement 4 so that the lower end of the punching section 16 slides to the upper end of the reinforcement 4, then the above-mentioned punching step is repeated so that the piling section and the punching section 1 move down again, the lower ends of the punch 12 and the punching section 16 deepen the depth of the hole again, and after the lower end of the piling section comes into contact with the top of the reinforcement 4, the reinforcement 4 is inserted down into the soil under the inertial action of the piling section.
The soil below can further be tamped when the lower extreme of rib 4 in this scheme moves down, also can carry on spacingly to the soil of hole lateral wall simultaneously, avoids the soil around the hole of beating to sink.
Example 2
On the basis of embodiment 1, as shown in fig. 3, the upper end of the vertical plate 32 in this embodiment is bent to the side close to the punching section 16, and as shown in fig. 4, the vertical edge of the same side of the vertical plate 32 and the connecting plate 31 is bent to the side close to the punching section 16, when the punching portion 1 moves to the ground and rotates counterclockwise, the bent inclined surface can guide and compress soil, prevent the protruding soil from falling between the vertical plate 32 and the punching section 16, and further improve the compression effect on the soil.
The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
