Vibro Equipment for Stone Columns and Compacted Sand/Gravel Piles

Typical Equipment Configurations

KLV400, KLV550, KLV650, together with EP400B, EP550B, EP550C, EP650B, and EP800B configurations adapted for stone column and compacted sand/gravel pile construction.

Key Technical Range

• Motor power: approximately 300–600 kW
• Eccentric moment: approximately 400–670 kg·m
• Operating frequency: approximately 580–750 r/min
• Maximum centrifugal force: approximately 150–252 t
• Maximum extraction capacity: approximately 90–120 t
• Typical column diameter: approximately 800–1,000 mm, depending on equipment configuration, construction method, and ground conditions

Construction Method

The casing is driven to the required treatment depth by vibratory penetration. Stone, gravel, or sand is then placed in stages, while controlled vibration and casing extraction compact the fill and form the ground-improvement column.

Equipment parameters and construction procedures can be adjusted according to soil conditions, treatment depth, column diameter, pile spacing, and required productivity.

Representative Applications

The equipment is used for stone columns, compacted sand piles, and sand/gravel piles in soft-ground improvement projects, including ports, terminals, airports, highways, industrial facilities, reclamation areas, and other major infrastructure works.

Representative applications include stone column and compacted sand pile works at port projects in Zhoushan, China, as well as stone column ground improvement for Lot 3 of the E60 Highway project in Georgia.

Engineering Support

Project-specific support includes vibro hammer selection, casing configuration, aggregate-placement method, construction parameter matching, and monitoring of operating current, casing penetration depth, and extraction speed.
