In engineering construction, although the tamping project is a basic project, it plays an important role. After the completion of the highway project, the subgrade needs to be compacted mechanically to avoid settlement or collapse. Rapid impact compactors can solve this problem well. Let's share the construction principles and advantages of rapid impact compactiors.

Rapid impact compactors have two compaction forms in practical applications: free fall compaction; forced accelerated compaction. Free fall compaction refers to the use of the force generated by the free fall of the heavy object when it falls naturally in the air for compaction. The hydraulic cylinder lifts the rammer to a certain height and releases it. At this time, the hammer body falls freely and contacts the hammer pad on the ground. When the hammer pad generates pressure, it hits the assembly of the pituitary body and the rammer plate, which drives the rammer plate to compact the ground. In forced acceleration tamping mode, while releasing the pituitary gland, it responds by applying velocity to accelerate its fall. When the hammer pad generates pressure, it hits the assembly of the pituitary body and the rammer plate, which drives the rammer plate to compact the ground. Rapid impact compactor is actually a compactor that compresses soil by combining the gravity and variable force of the machine, also known as dynamic compaction technology. Dynamic compaction technology is mainly used for roadbed reinforcement, which can improve the strength and density of soil.

(1) After compacting the loose soil, the soil density needs to be measured, and the compaction degree should be kept above 96%. This kind of compaction is better, and the compaction efficiency is high. Compared with other types of compaction modes, embankment has obvious advantages, and other equipment is difficult to achieve such compaction effect. The adjustment of the tamping degree can be determined according to the deformation degree of the rammer, and the actual tamping strength needs to be analyzed according to the specific situation.

(2) Analyze the compaction depth. In the construction operation of the general compactor, the filling thickness of the rapid impact compaction is 25~40cm. The filling depth of the rapid impact compactor is 1.8m. The compaction effect is obvious.

(3) In the compaction particle size analysis, the rapid impact compactor can record the soil deformation in actual operation, and detect the compaction effect according to the soil density. This technology is beyond the reach of other ordinary compactors.

(4) Rapid impact compaction method is a subgrade construction technology with high degree of automation and good construction effect. There are many construction methods, such as subgrade filling, gravel soil, platform backfill, loose filling, etc., which are widely used in actual highway subgrade construction.
