Rapid impact compaction equipment manufacturers mainly produce and sell HC type rapid impact compactors, with an impact energy of 42KJ and a price of about 100,000-150,000. The specific price needs further consultation. Rapid impact compactor is a kind of equipment widely used in roadbed treatment and compaction. It is easy to use and easy to disassemble. It can be used with various types of excavators, loaders and other road machinery. The price is relatively reasonable and cost-effective.

1. It is the reinforcement and compaction of high soil fillers. This operating mode is mainly suitable for slopes and grooves. The characteristics of subgrade soil in these areas are relatively prominent. Reinforced with rapid impact compaction filling stone, especially in areas with narrow roads and small working surfaces, good construction results can be achieved.

2. Strengthen and consolidate the back and culvert side of the platform. With the continuous improvement of highway construction level in my country, higher requirements are put forward for highway subgrade construction. During the construction process, a large number of culvert structures were added. The retaining walls at the back of the platform and the side of the culvert are filled by rapid impact compaction. These reinforcements are significantly more efficient due to the flexibility and adjustability of the construction process.

3. Filling and excavation during construction. The rapid impact compactor has a significant compaction effect on the leveling of the roadbed. The construction gear of the rapid impact compaction can be adjusted according to the soil density during the construction process to ensure the construction effect.

According to the different descending methods of the hammer body, the operation modes of the rapid impact compaction can be divided into free drop hammer type and forced drop hammer type. Free fall hammer type (single function): the hydraulic cylinder lifts the hammer body to the set height, and the hammer body falls freely; after the hammer body descends, the assembly of the hammer body and the compaction plate is hit by the hammer pad to drive the compaction plate to be compacted ground. Forced drop hammer type (dual function): The hydraulic cylinder lifts the hammer body to the set height, and then quickly reverses the force, and the hammer body accelerates and descends under the combined action of gravity and the thrust of the hydraulic cylinder; after the hammer body descends, the hammer body and The assembly of the compaction plate is hit by the hammer pad, which drives the compaction plate to compact the ground. The hammer impact of a high-speed hydraulic compactor is an assembly of the hammer pad, lower hammer and compaction plate, rather than impacting the ground. The pressure means that the compaction plate of the rapid impact compaction is always pressed against the ground, exerting lower pressure on the ground, without the kinematic character of the shock, more like a masseuse massaging the pressure suddenly.

It can be seen that according to the structural characteristics of mechanical products, rapid impact compactors can be divided into compactors; according to their action on the ground, rapid impact compactors belong to power compactors.

Analysis of rapid impact compactor in reinforcement

Some researchers have pointed out that the HC Rayleigh surface wave rapid impact compactor (R) accounts for 67.3% of the total energy in the entire semi-infinite elastic space wave field, and the shear wave (S-wave) accounts for 25.8% of the total energy. If It is only considered that the compression wave (P wave) of the HC rapid hydraulic compressing press accounts for 6.9% of the total energy to contribute to the reinforcement of the dynamic compaction, so the interpretation of the energy utilization is unreasonable. Then, according to the Rayleigh surface wave, (R These researchers propagate not only near the surface, but also near the surface. The HC is within a certain depth within the reinforcement range of the rapid impact compactor. Therefore, it is speculated that the R-wave, which accounts for the largest part of the total energy, may also play a role in the reinforcement of the foundation soil by dynamic compaction. important role.

42KJ rapid impact compactor is also called hydraulic tamper, etc. It is driven by loaders and excavators. Its working principle is mainly to use the hydraulic system to lift the rammer to a certain height, and then force the rammer to drop, so as to play the role of the tamper. effect.
