The operation method of Rapid Impact Compaction

Product Overview

Rapid Impact Compactionwhich means that high-speed means that it can quickly reach the tamping site and carry out high-speed and effective tamping work, so how does the hydraulic tamping machine work quickly? Rapid Impact Compaction require loaders and excavators to carry, walk and drive, the following for everyone to share a picture of Rapid Impact Compaction with excavators and loaders.

As a safe and environmentally friendly Rapid Impact Compaction, it is composed of a rammer, a ramming frame, a rammer plate, and a hydraulic drive device. The technical principle of hydraulic rammer is: use the hydraulic cylinder to lift the rammer hammer to a certain height and release it. The rammer is accelerated by the combined action of gravity and hydraulics. Trailing behind, hit the ram plate with cushion, statically pressed to the ground, and then tamping the ground by the Rapid Impact Compaction rammer plate. Since the Rapid Impact Compaction is implemented on the ground by ramming plates with cushions and static pressure on the ground, compared with the traditional compaction technology, compared with the continuous action of the Rapid Impact Compaction, its force peak is small, the action time is long, the function is soft, it is not easy to cut and fill the streamline, and it has the functions of dustproof and splash-proof. Compared with the traditional surface rolling technology, the hydraulic compactor has strong penetration and uniformity, and it is not easy to form surface hardening in the basic treatment, which can obtain a more uniform density in a large depth range. As a general Rapid Impact Compaction, in order to ram the structure without ramming plates, the mechanism of action of the ground has a large compaction strength with the traditional compaction technology (strong ramming, etc.), and can also be used to crush the ground and other structures.

According to China's current construction technology, in the construction area of the subgrade project high fill subgrade project, the traditional design scheme handicraft is impact rolling and static pressing pile. These two kinds of mechanical equipment have problems such as mechanical equipment entering the site trouble, high cost of static pressing piles, and inconvenient management. If reasonable consolidation is not carried out, of course, the settlement of the foundation after the construction will not be prevented, resulting in the settlement of the foundation of the subgrade project. Rapid Impact Compaction raise the rammer to a certain aspect ratio according to the hydraulic cylinder and then release it quickly. The rammer indirectly compacts the road surface according to the ramming board during the whole process of accelerated landing. Loader hydraulic rammer installation equipment is located on the boom of ordinary small forklift, easy to move, can click or continuously compact the working surface, complete high-frequency high-toughness compaction work, affect the depth of 3 meters, fully guarantee the actual effect of compaction.

Operation method of Rapid Impact Compaction

1. Rapid Impact Compaction further reduces sand, removes or weakens the vertical symmetry of sand, the virtual beam combination is poor, the construction site strictly controls the overall quality of the subgrade project, reinforcement is not suitable for overpressure, overpressure is easy to cause nearby sand pressure, destroying the original structure.

2. The original pavement reinforcement effect is remarkable, and should be marketed, promoted and applied; After the Rapid Impact Compaction subgrade engineering is filled with a 1m aspect ratio, the point rammer can be selected instead of impact rolling; After the subgrade project is filled with an 8m aspect ratio, a fully rammed pile is used instead of a hydrostatic pile.

3. In the whole process of subgrade engineering reinforcement, if part of the foundation settlement is too much, reinforcement countermeasures should be taken according to the specific situation, that is, 3 to 6 hammers are filled in the middle of the four ramming points of the Rapid Impact Compaction, which improves the actual effect of the overall reinforcement and is also conducive to the flatness of the overall excavation work surface.

4. For some excavation work surface narrow filling subgrade edges, the flexibility of high-speed hydraulic impact tamping machine should be fully utilized. The fast footprint is small, further enhancing the practical effect of filling the edges of the subgrade and the chicken claw landform.

5. In the three-back reinforcement work, one side should be compacted according to the standard from both sides to the middle; Culvert backfilling must ensure that the matching layers on both sides of the hole are reinforced; Before reinforcement, offset monitoring observation points and real-time monitoring systems should be set up. If it is found that the asymmetric pressure during the entire working process changes the structure, the ramming potential should be reduced and the ramming frequency of the Rapid Impact Compaction should be increased.
