The use effect of rapid impact compactor, in which fields can rapid impact compaction machine be used?

The role of rapid impact compactors is reflected in high energy. Rapid impact compaction machine has the advantages of high compaction energy and large impact depth, and can obtain more uniform compaction in a larger depth range. The compaction depth of the rapid impact compactor is 1-3m, and the impact depth is 4-10m, second only to dynamic compaction.

Take the subgrade settlement of 100mm after reinforcement by a 36kj rapid impact compactor as an example: 70% of the settlement occurs within the effective compaction depth of 2m, and the rest of the settlement occurs within the impact depth of 4m, then the average compressibility of the soil within 2m below the surface With an increase of 3.5%, the average compressibility of soil in the range of 2-4m below the surface increased by 1.5%.

Before the popularization of rapid impact compactors, due to the influence of construction conditions, in the construction of highway bridges, large compactors at the backfill of bridges and culverts were difficult to achieve all-round compaction, while small compactors were compacted but not compacted. The phenomenon has occurred from time to time, or in recent years, with the increase of traffic flow and vehicle carrying capacity, the rigid requirements of road carrying capacity can no longer be met.

The rapid impact compactor has a large compaction force, which can obtain relatively uniform density in a large depth range, with soft effect, strong and uniform penetration ability. It reduces or avoids slippage and separation between layers that can be caused by layered compaction techniques, and does not easily form surface hardening during base treatment. At the same time, the transition is flexible and convenient, and there is no dead angle for on-site compaction.

The vertical deformation of the ground compacted by the rapid impact compaction machine can reach more than 10cm, which can significantly improve the density of the backfill, accelerate the elimination of the settlement of the backfill within a certain depth range, and effectively improve the quality of the backfill project, second only to the dynamic compactor. It has a significant impact on early damage to the road surface after partial foundation subsidence of highways and other major facilities, such as abutment jumping, pier tilting, and slope slippage.

According to different construction requirements, HC series rapid impact compaction equipment can be used for flat compaction, step compaction, groove compaction, slope compaction and other compaction operations; after reassembling the breaker, it can be used for crushing roads and sites; Eco-friendly compactors can be used for piling and piling when necessary.

The rapid impact compactor can be widely used in the compaction of highway and railway roadbeds such as platform backs, culvert sides, and chicken feet, the compaction and reinforcement of embankment and slope protection and leakage treatment, and the foundation compaction of large-scale infrastructure such as oil depots, airports, and ports. Landfill compaction of sanitation waste and hazardous substances, compaction and reinforcement of military facilities, etc. Rapid impact compactor is especially suitable for narrow construction sites, such as highway, railway, port water conservancy and other infrastructure construction and maintenance departments, sanitation departments, military and other very powerful construction equipment.
