[0010] As a preferred technical scheme, the pressing column is connected to the inside of the compaction inner hole in a matching manner, and the plurality of anti-skid spikes are arranged in parallel.

[0011] As described above, the compaction device for dredging and backfilling has the following beneficial effects: the outer side of the pressing column is fixed to the top mounting ring through the positioning plate when the pressing column is pressed, so that the mounting of the supporting mounting rod and the pressing ring is realized, the pressing ring is movably arranged around the outer side of the compaction installation cylinder after the pressing column is pressed, the pressing column is accurately pressed into the compaction inner hole for impact, and the error during impact is prevented, and the device is more convenient to use; when the compaction bottom plate is placed on the soil for tamping, the plurality of anti-skid spikes below the compaction bottom plate play a role of preventing skidding, and after the pressing ring moves downward around the compaction installation cylinder, the pressing ring moves downward to press the fixing ring, so that the fixing ring drives the ground positioning claws to move downward, and then the plurality of ground positioning claws are supported on the ground to realize the support of the device, the loosening of the sludge soil is prevented to prevent the device from tilting, and the device is more convenient to use for compacting the excessively soft soil.
