Abstract
This invention relates to a vibratory compactor for ultra-deep vibratory compaction construction, comprising a vibratory compactor body shell, a first water channel provided in the vibratory compactor body shell, a detachable guide rod assembly coaxially connected above the vibratory compactor body shell, a shock absorber installed between the detachable guide rod assembly and the vibratory compactor body shell, a second water channel provided in the detachable guide rod assembly, and a third water channel provided within the shock absorber, with the first and second water channels connected via the third water channel. This invention enables vibratory compaction of rock in strata exceeding 40 meters in depth, requiring a low-profile, low-cost, and highly safe piling frame that avoids hole jamming. The detachable guide rod assemblies primarily employ tapered thread insertion connections, reducing misalignment and errors between the two axes during connection, minimizing the impact on the connection, and ensuring good sealing after connection. The shock absorber provides excellent damping, preventing loosening of the detachable guide rod assemblies.
