rapid impact compactor is a technology related to dynamic compaction, which can be used to improve the bearing capacity of soil through controlled impact. This treatment is effective on the top floor, usually up to 6m deep, but in some cases, it has been improved to 9m conditions. 30-80 times per minute, drop a 1-10 ton (depending on the size) hammer on the special foot assembly, and the foot is always in contact with the ground.
What is rapid impact compaction machine
rapid impact compactor is a technology for improving the ground to compact shallow, loose and granular soil. The soil treated in this way will increase the density, friction angle and overall stiffness, thereby increasing the bearing capacity and reducing the settlement of the planned structure. The rapid impact compaction machine is composed of a hydraulic hammer installed on the excavator repeatedly hitting a circular plate on the ground. Then, because the feet of the rapid impact compactor keep in contact with the ground, the energy is safely and effectively transferred to the ground, thus avoiding the fear of flying debris. The rapid impact compactor can densify the loose filled soil with a depth of 6 m or more. Other benefits of the rapid impact compactor include increasing the bearing capacity of the soil, minimizing settlement, and creating a unified support for the foundation.
Construction method of rapid impact compactor
The method of effectively covering the ground varies from country to country. Common patterns for overlays use three tracks to pass through (see figure below). First compact the outer (black) point, then the middle (Orange) point, and finally the fill (blue) position. This has the effect of achieving the best depth of influence. The depth of the affected ground exceeds the latter.
The rapid impact compaction equipment can record the work done. Adjust the target standard setting for final setting, depth, and blow count. Then, the driver compacts until one of the standards is reached, and then moves the machine. The visual representation of data is seen in the cab and recorded by the on-board monitor.
The ground near adjacent sites can be compacted by rapid impact compactors. The rapid impact compactor is suitable for ground improvement in small spaces. For example, we can apply this technology in or near the existing warehouse. In this case, we will carefully monitor the vibration of adjacent structures during the construction of the rapid impact compactor.
Ideal application of rapid impact compactor
The ground is densified, the liquefaction is relieved, the bearing capacity of the pile side is increased, and the foundation and cushion are supported. Ideal application of rapid impact compactor:
Loose sandy soil site with low silt and clay content.
Water filling and debris filling points.
Contaminated soil and landfills.
Short time and fast construction plan.
The excavation may be 5 to 20 feet to redesign the fill.
Places where noise and vibration can be tolerated and tolerated.
