when the hard soil layer breaking drill bit 602 breaks a hard soil layer, if the hard soil layer breaking drill bit 602 receives larger resistance and reaction force, the hard soil layer breaking drill bit 602 retracts into the buffer groove and extrudes the buffer spring 605 to elastically deform, so that a certain buffer protection effect can be achieved on the hard soil layer breaking drill bit 602;
in the process that the transmission seat 601 performs reciprocating lifting movement in the transmission port 5, the transmission seat 601 also drives the transmission sleeve 707 to perform synchronous movement, the transmission sleeve 707 simultaneously drives the plurality of soil compaction vibrators 701 to enter soil around the impact drilling hole, vibration generated by operation of the foundation pile drill rod 402 is respectively transmitted to the plurality of soil compaction vibrators 701 through the transmission sleeve 707, the plurality of soil compaction vibrators 701 vibrate in the soil, the compactness of the soil can be improved, when the empty drum phenomenon occurs in the soil, the transfer spring 706 starts to perform elastic reset movement due to the fact that the resistance acting on the auxiliary vibrators 703 is reduced, in the process, the transfer spring 706 drives the transfer shaft 705 to rotate in the transfer sleeve 704, the auxiliary vibrators 703 gradually stretch out of the folding port 702 and gradually enter the soil layer, the auxiliary vibrators 703 stretching out of the folding port 702 can expand the action range of the soil compaction vibrators 701, and therefore the stability of the soil layer around the foundation pile drilling hole is further ensured, the fact that part of loose soil falls into the foundation pile after the spiral blades 403 are effectively prevented from being taken out, and secondary cleaning is avoided;
in the process of foundation pile drilling construction operation, the third hydraulic cylinder installed on the directional sleeve 13 is required to push the tamping block 11 to lift upwards, the tamping block 11 extrudes the pressure accumulation spring 12 in the process of lifting upwards and enables the pressure accumulation spring 12 to elastically deform, then the supporting effect of the third hydraulic cylinder on the tamping block 11 is quickly removed, the tamping block 11 is strongly impacted on the directional sleeve 13 under the combined effect of self gravity and the reactive force generated when the pressure accumulation spring 12 recovers deformation, and therefore the soil around the foundation pile drilling can be tamped, and the stability of the soil layer around the foundation pile drilling is further improved.
The present invention is not limited to the above-mentioned embodiments, and any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed within the scope of the present invention.
