What is the purpose of rapid impact compaction? Where are rapid impact compactors used?

The main purpose of the rapid impact compaction is to improve the soil structure, so as to solve the problems of roadbeds and foundations such as highways, railways, airports, and ports.

Rapid impact compactor application

Reinforcement and compaction of high soil fill. This operation mode is mainly suitable for slopes and trenches, where the characteristics of the subgrade soil are relatively prominent, and rapid impact compaction equipment is used to fill the stone for reinforcement, especially in areas with narrow roads and small working surfaces, which can achieve good construction results.

Reinforce 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, and the retaining walls at the back of the platform and the side of the culvert were filled with rapid impact compaction machines. These reinforcement operations are significantly more efficient due to the flexibility and adjustability of the construction process.

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 high-speed hydraulic compactor can be adjusted according to the soil density during the construction process to ensure the construction effect.

Application scope and characteristics of rapid impact compactor

The rapid impact compaction equipment has undergone rigorous testing and verification in many construction sites. According to the field test results, it has the following application characteristics:

It can realize the overall compaction of the thick filling layer, improve the productivity, and reduce or avoid the phenomenon of interlayer slippage and separation that may be caused by the layered compaction technology. After the thick layer fill is compacted, the density can reach more than 95% evenly.

The rapid impact compaction can deal with the foundation of the existing large-scale compaction or compaction machinery, such as the back of the abutment, the side of the culvert, the periphery of the bridge pier, the slope, the turning area of the compactor, and the area without roads, and solve the common expressway. Problems such as early road damage, bridge abutment jumping, bridge pier skew, and slope slippage after local foundation subsidence of other important facilities.

It can be used for reinforcement of river dams. The current soil dams constructed and reinforced with medium and small compaction machinery layer-by-layer compaction technology are solid on the side and virtual on the upper side, and it is impossible to solve the problems of soil layer infiltration and slope slump when the flow rate is large. High-speed hydraulic compactors help solve this challenge. Its variant, the Universal Compactor (straight compactor), helps to cut off the piping.
