Vibro
Concrete Columns are constructed in the ground with
a bottom feed vibratory probe. The technique will
densify granular soils and transfer loads through
soft cohesive and organic soils.
Vibro
Concrete Column Applications
Reduction of foundation settlement
Improvement of bearing capacity
Slope stabilization
Economical piling alternative
Important
Vibro Concrete Column Parameters
Ground type
Relative density
Structural Load
Vibro
Concrete Column Effectiveness
Best suited to transfer loads through
soft and/or organic layers to an underlying granular stratum.
Vibro
Concrete Column Design Parameters
The analysis and
design of the Vibro Concrete Column improved site is essentially
the same as would be performed for any expanded base pile foundation
except that the improved soil parameters are used.
Vibro
Concrete Column Design Steps
Perform site investigation
Soil type and strength important
Calculate predicted settlements
Problem understood
Establish requirements
What settlements, bearing capacity are allowable
Design Vibro Concrete Column approach
Number of Vibro Concrete Columns required to achieve desired
results. Review the need to incorporate pile cap design
or develop reinforced soil load transfer system.
