HC84 rapid impact compaction machine Effect-rapid impact compactor Model Parameters

The rapid impact compaction machine solves the problem of jumping at the bridge head during the construction of the expressway, and can also be used for the construction of large and medium-sized infrastructure such as petrochemical plants, seaports, airports, and underground parking lots. Landfill compaction, etc. Rapid impact compaction is also called "rapid impact compaction machine", "rapid impact compactor", etc. It is a new compaction construction machinery and equipment in recent years. The equipment, hydraulic transmission system, electronic control system and other components are immediately installed in engineering project machines such as forklifts or excavators, and the hydraulic output of excavators and loaders is immediately used.

The function of the rapid impact compaction machine is reflected in the higher energy. The rapid impact compactor has the advantages of high tamping kinetic energy and large damage depth, and can obtain a more uniform compaction degree within a relatively large depth range. The rapid impact compactor has a tamping depth of 1~3m, The hazard depth is 4-10m, second only to the rammer. Therefore, some people call the rapid impact compaction machine a hydraulic dynamic rammer. Take the settlement of 100mm of roadbed engineering after ribbing by 36KJ rapid impact compaction equipment as an example: 70% of the settlement is set to occur within 2m of the reasonable compaction depth, and the rest occurs within 4m of the hazard depth, and the sand within 2m below the surface The mean compressibility is increased by 3.5%, and the mean compressibility of the 2-4m sand under the surface layer is increased by 1.5%. The efficacy of hydraulic compactors is also reflected in high efficiency and speed. The original design of rapid impact compactors is to quickly repair construction machinery and equipment. Rapid impact compaction machines can be quickly and easily assembled on forklifts or excavators. At the same time, automation The technical automatic control system brings the possibility of rapid engineering construction. Therefore, another alias for the hydraulic compactor is the rapid impact compaction machine.

Impact rollers are also called "impact rollers", "plum impact rollers", "impact rollers", etc. They are divided into trailed impact rollers and self-propelled impact rollers. They are also a new type of compaction construction machinery in recent years. It is composed of traction mechanism, non-circular impact rolling wheel and other components. The impact compacting wheel drives the impact rolling wheel to work under the traction of the traction device. At present, the trailer impact roller is mostly used in the market.

The common feature of rapid impact compactor and impact roller is that both use huge impact force to tamp the foundation. It can generate large shear stress and normal stress in the soil, so as to effectively overcome the cohesive force of the cohesive soil, compress the soil and remove the air and water in the soil. Because the impact time is very short, the impact is often over before the pressed material has time to "flow", so the instability caused by the "flow" of the soil can be reduced, and it can be effectively used for high water content Compaction of clay and dry sand is also very effective on gravel roadbeds.

The shock wave formed by the shock energy can be transmitted to a very deep depth, so it has absolute advantages in terms of compaction depth and early elimination of foundation settlement. Many friends in the engineering industry have little understanding of the new and more used compaction equipment in recent years.

Both rapid impact compactors and impact rollers use huge impact force to consolidate the foundation, and early elimination is the common point of rapid impact compaction equipment and trailed impact rollers, and there are certain differences between the two. The role of the hydraulic compactor is reflected in the fact that it can remove or weaken the inherent problems and artificial shortcomings of the stratified rolling subgrade project, and it will be possible to remove the post-construction settlement early in the basic service life. Therefore, rapid impact compaction machine are widely used in areas where large and medium-sized impact rolling machines and equipment such as highway bridges, small and medium-sized structures and support structures, as well as impact rollers, compactors and other large and medium-sized impact rolling machines and equipment cannot be constructed.
