The Rapid Impact Compaction operation method

Product Overview

Rapid Impact Compaction has become a new type of ramming compaction equipment widely used in subgrade pavement engineering construction, compared with the traditional manual compaction and small compaction equipment, excavator hydraulic compactor has the advantages of convenient transition, flexible and efficient, safe and environmentally friendly, good control performance, and high ramming energy.

The Rapid Impact Compaction operation method

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 hydraulic impact rammed machine 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 hydraulic impact ramming machine, 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 Rapid Impact Compaction 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.

The characteristics of Rapid Impact Compaction

1. Convenient transition, flexible and efficient, good control performance. The Rapid Impact Compaction is installed on the excavator or loader of the equipment, the process of transfer and construction is very flexible, and the operation is very simple, which greatly improves the construction efficiency and reduces the construction cost.

2. Safe and environmentally friendly, eliminate noise. The hammer body of the Rapid Impact Compaction is placed in the skin, which can greatly reduce the accidental damage to people, and at the same time has a very large effect on eliminating noise, thus playing a safe, low-noise and other effects.

3. The impact on adjacent structures is much smaller than other compaction methods. Rapid Impact Compaction in the construction, the direction of force propagation is mainly vertical downward, the impact on other adjacent structures is small, can be close to the abutment, retaining wall and other structures for construction, safe and reliable.

4. High speed and high efficiency, cost saving. The ramming frequency of the hydraulic rammer produced by Rammer God is 30-80 times per minute, which significantly improves the work efficiency, and the ramming frequency occupies the front row position in the same industry.

5. Widely used and suitable for all kinds of fillers. The Rapid Impact Compaction is not sensitive to the cost of the filler and the moisture content, and has obvious compaction effect.

6. Independent research and development and production, continuous product innovation. HC high-speed hydraulic tamping machine was invented by Cao Bin, chief engineer of our factory, in 2002, and named after it, our factory has been continuously updated to six generations, and has passed the inspection of Xi'an Road Construction Machinery Inspection Center of the Ministry of Transport.
