新振动锤 OMS OVF 300-4 Taş Kolon Ekipmanı

The OMS vibro compaction method is mostly used in granular soils that are at seismic risk and thus, the method itself is suitable for land reclamation projects to mitigate the risk of liquefaction. This technique is for densifying sand-like soils on site by means of an OMS Vibroflotation probe. With the simultaneous vibration and saturation impact, loose sand particles are repacked into a more compact state and lateral confining pressure within the sand mass is increased.
The vibro compaction technique is most suitable for medium to coarse-grained sand with silt content. Cohesive soil consisting of silt and clay material does not respond to vibratory compaction.

Operation Procedure of Vibro Compaction:

1. Penetration: The OMS vibroflot probe is penetrated to the depth required by the project with the vibration effect and water jet.
2. Compaction: Compaction is a process that continues as the vibroflot is pulled up. The probe is pulled up to a certain level and the ground walls are compressed with an action like penetrating again.
3. Refill: After the ground is slightly compressed, the same as the project’s gravel or different type of granular material is poured into the cavity by feeding on the top. The process is continued by moving the probe up and down the soil and vibrating it at the same time.
4. Finishing: After the process is completed, the compacted gravel column and settlement of the soil had achieved.

Operation Procedure of Vibro Replacement:
1. Penetration: The OMS vibroflot probe is penetrated to the depth required by the project with the vibration effect and compressed air. Laterally rotated eccentric weights of the probe create an empty space in the soil.
2. Compaction: After reaching the desired depth, the probe is pulled up for a while. The gravel, inside the pressurized silo, is discharged to the empty volume/space by the gravel discharge tube. During the re-penetration, the gravel is compacted and pressed into the surrounding soil.
3. Finishing: When repeating the compaction process, the stone column created up a surface level. During the final leveling, the surface is to be re-compacted.
