Is compaction process rapid? Rapid Impact Compaction

The tamping frequency of rapid impact compaction machine is generally about 30-80 times per minute. The tamping depth and tamping frequency produced can be controlled by the controller. However, in actual engineering, it is affected by many aspects, which will affect the compaction frequency and compaction depth. At the same time, there are many external factors that affect the construction quality, including materials, machinery, methods, environment and personnel.

According to the requirements of the drawings, the subgrade surface of the foundation of the rapid impact compactor needs to be leveled to ensure that the subgrade of the rapid impact compactor is evenly impacted and achieve the expected impact rolling effect. During the pressing process, obstacles should be clearly marked on the ground, such as underground structures, pipelines, cables and other facilities within the construction scope. During the pressing process, obstacles should be clearly marked on the ground, such as underground structures, pipelines, cables and other facilities within the construction scope.

Before construction, collect all relevant information on the site, plan the construction according to the construction period requirements, construction conditions and climatic conditions, and reasonably arrange the number, operation and construction time of rapid impact compaction equipment.

Complete the construction work in accordance with the requirements of the "Technical Specification for Highway Subgrade Construction", complete the re-measurement of the wire, the center line, the leveling point, the cross-section inspection and the supplementary measurement, and the addition of the leveling point. The embankment toe and berm shall be determined according to the requirements of the design documents.

As for the rapid impact compactor, although the operators and mechanical equipment are easy to fix, once the construction environment changes, due to the influence and constraints of external factors such as the properties of basic materials, water content and road construction requirements, it may be necessary to change the construction method or construction process. Of course, construction personnel or designers can also summarize and accumulate more construction experience. During the construction process, if the construction requirements are closer to the previous construction environment and construction requirements.

Under the action of gravity and hydraulic pressure, the rapid impact compactor realizes the working surface through the compaction hammer, and at the same time, the gate moves up and down rapidly under the action of the hydraulic device. Rapid impact compaction machines are pulled by loader or excavator supports. In order to achieve the purpose of rapidly changing the compaction position, the subgrade joints are compacted by backfilling three times to improve the overall construction quality of the subgrade, effectively reduce the post-construction settlement of the joints, and make up for the quality defect that the large domestic compactors cannot compact in place. 

Rapid impact compaction can solve this problem well. The working principle of the rapid impact compaction is to use the hydraulic cylinder to send the tamper to a certain height, then quickly release it from a certain height, and accelerate downward under the combined action of gravity and hydraulic accumulator. The rammer accelerates backwards and hits the tamper plate with a special pad. The function of the rammed plate is to maximize the transmission of vertical impact forces to the ground.
