Compaction Methods Vibro GmbH Machines for Deep
2021. 3. 3. No danger to the stability of the structure where there are dynamic loads, for example, power station turbines, machines producing oscillation, earthquakes etc. According to the kind of soil to be compacted we differentiate between three main methods, the sand compaction method for non-cohesive soils, the stone column method for cohesive soils and the concrete column method as a special

Experimental and Numerical Studies on the Performances
Stone columns (SCs) and sand compaction piles (SCPs) are widely utilized as effective methods to increase the bearing capacity and reduce the settlement of soft ground. In this study, a physical model test was conducted to compare the performances of the SC- and SCP-improved Hong Kong Marine Clay (HKMC) grounds.

Sand Compaction Pile an overview ScienceDirect Topics
The machine used and the operational time for the CS–clay piles were reported to be similar to those for the marine sand piles, Therefore, vibro replacement, constructing the stone columns, and sand compaction piles can be proposed as appropriate methods to improve the geotechnical characteristics of the areas near to the Qeshm

Comparison Between Stone Columns and Vertical Geodrains with
2020. 10. 13. - The soil reinforcement by stone columns (or by sand piles). Each of the two alternatives has specific advantages. Indeed, by the technique of geodrains, which is characterized by a rapid installation, the consolidation of soft ground is well accelerated. Meanwhile, a staged construction for embankments is necessary. Whereas the stone columns

What are stone columns? Earthquake Commission
2015. 11. 2. Stone columns are constructed by experienced contractors using specialist equipment. The construction uses an excavator with a vibrating probe to feed stone into the ground, forming a vertical column of stone. Some stone column rigs feed stone into the ground through the vibrating probe, exiting at the bottom, and other rigs require the stone
