Description

[0002] Dynamic compaction is also known as dynamic consolidation. It uses a large crawler-type dynamic compaction machine to drop a 8-30 ton hammer freely from a height of 6-30 meters to compact the soil, quickly increase the bearing capacity and compression modulus of the foundation, form a relatively uniform and dense foundation, and change the pore distribution of the foundation soil within a certain depth of the foundation. Dynamic compaction construction has been widely used in highways, railways, airports, nuclear power plants, large industrial areas, port reclamation and other foundation reinforcement projects.

[0003] In existing construction, when backfilling and tamping are carried out by the strong tamping method, a heavy hammer is dropped from a height to compact the hole. However, the heavy hammer used in the backfilling and tamping of the hole usually adopts a cylindrical structure, and the cylindrical heavy hammer has a situation of local adhesion to the soil after falling, resulting in a center of gravity shift when it falls next time, affecting the quality of the work, and the tamping cycle of each heavy hammer is long, and it is impossible to perform repeated tamping operations after falling.

[0047] Working principle: When performing compaction operation, the first drive motor 4 drives the retracting and releasing frame 3 to rotate, and the retracting and releasing frame 3 lifts the compaction column 705 by winding the wire rope 5. The compaction column 705 drives the counterweight iron column 12 to move upward synchronously, and the counterweight iron column 12 moves to the top and is adsorbed by the electromagnet 11. At this time, the first drive motor 4 is powered off, and the compaction column 705 falls down under the action of gravity to compact the ground, and the guide tube 703 guides the fall of the compaction column 705. Subsequently, the electromagnet 11 is powered off to make the counterweight iron column 12 fall and hit the compaction column 705. In this way, the compaction column 705 performs secondary compaction operation, and the push rod motor 706 lifts the counterweight iron column 12 multiple times through the extrusion plate 707, so that the counterweight iron column 12 hits the compaction column 705 with high frequency, which facilitates the compaction column 705 to perform high-frequency compaction operation.

[0048] When the compacting column 705 needs to be lifted, the third driving motor 802 drives the movable ring 804 to rotate through the gear 803 and the gear ring 805, and the movable ring 804 drives the cleaning ring 806 to rotate. The cleaning ring 806 cleans the soil on the compacting column 705 through a wire brush, thereby preventing the soil attached to the compacting column 705 from affecting its center of gravity.

[0049] The screw 601 is driven to rotate by the second driving motor 603 through the first active bevel gear 604 and the first driven bevel gear 602. After the two screws 601 are transmitted through the pulley 605 and the belt 606, the lifting frame 607 can be driven to rise and fall at the same time, and then the movable frame 608 can be driven to rise and fall. The lifting and lowering of the movable frame 608 can adjust the height of the tamping column 705 to facilitate tamping operations of different degrees. PLC19 controls the opening and closing of the solenoid valve 905, and the lubricating oil in the oil storage cylinder 902 flows into the sponge in the lubricating sleeve 906 through the oil outlet pipe 904, so that the sponge lubricates the wire rope 5, thereby reducing the wear of the wire rope 5 and extending the service life of the wire rope 5.

[0050] When the first drive motor 4 fails and cannot be used, the fourth drive motor 1002 drives the rotating shaft 1004 to rotate through the second active bevel gear 1003 and the second driven bevel gear 1005, and the rotating shaft 1004 drives the wire sleeve 1006 and the baffle 1007 to rotate to perform emergency winding on the wire rope 5, and the wire sleeve 1006 can guide the wire rope 5.
