The use of rapid impact compaction is mainly to improve the soil structure, thereby solving the problems of roadbeds and foundations such as highways, railways, airports, and ports.
Reinforcement and compaction of high soil fillers. This mode of operation is mainly suitable for slopes and grooves, the characteristics of the subgrade soil in these areas are relatively prominent, and the stone reinforcement is filled with rapid impact compaction, especially in areas with narrow roads and small working surfaces, good construction results can be achieved.
Reinforce the back culvert side of the reinforcement platform. With the continuous improvement of the level of highway construction in China, higher requirements have been put forward for the construction of highway subgrades. A large number of culvert structures were added during the construction process, and the retaining walls of the back and culvert side were filled with rapid impact compaction. Due to the flexibility and adjustability of the construction process, these reinforcement operations are significantly more efficient.
Soil filling and excavation during construction. The rapid impact compaction has a significant compaction effect on the flat subgrade, and 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.
The rapid impact compaction has been rigorously tested and verified at the construction site in many places. According to the results of field tests, it has the following application characteristics:
It can realize the overall compaction of thick fill layers, improve productivity, and reduce or avoid the phenomenon of interlayer slippage and separation that may be caused by layered compaction technology. After the thick layer is compacted, the compactness can be evenly reached by more than 95%.
The rapid impact compaction can handle the foundation of the existing large-scale compaction or compaction machinery such as abutment back, culvert side, bridge pier periphery, slope, compaction mechanical folding area, roadless area, etc., and solve the problems of early damage to the pavement after the partial foundation of common highways and other important facilities sinks, abutment jumping, bridge pier skewing and slope slippage.
River embankments can be reinforced. The current soil embankments constructed and reinforced by small and medium-sized compaction mechanical layer compaction technology are virtual on the middle and solid sides, and it is impossible to solve the problem of soil layer infiltration and slope collapse at large flow rates. Rapid impact compaction help solve this challenge. Its variant, the Universal Tamping Machine (Straight Rammer), helps to truncate pipe surges.
According to the different construction requirements, the rapid impact compaction can carry out a variety of tamping operations such as plane tamping, step tamping, groove pit tamping, inclined ramming, etc.; Rapid impact compaction can be used for road surface and site crushing after modification of breaker; The safe and environmentally friendly rapid impact compaction can be used for piling and piling if necessary.
