During vibro compaction, clean sand backfill is typically added at the ground surface to compensate for the decrease in soil volume from the densification process. The vibratory energy reduces the inter-granular forces between the soil particles, allowing them to move into a denser configuration, typically reaching a relative density of 70 to 85%.

How to Improve Soil Properties

Other Methods; 1. Surface Compaction. One of the oldest methods of soil densification is surface compaction. Construction of a new road, a runway, an embankment or any soft or loose site needs a compacted base for laying the structure. If the depth to be densified is less, the surface compaction alone can solve the problem.

Deep Compaction Techniques

A large mass is dropped onto the ground surface c ausing compaction and long-term consolidation. Vibration. Densification is achieved by a vibrating probe or pile, sometimes aided by water jets or pressurized air and the addition of granular mater ial, possibly with added cement agen s. surrounding soil. Vibration is most suitable for free.

vibro compaction Balfour Beatty

Vibro compaction construction sequence appLications The water jetting and horizontal vibratory action of the vibroflot acts to compact the loose soils into a denser condition and significantly improve the bearing capacity of the treated ground. The vibro compaction technique is well established for use in tank farm, port and marine structure projects.

Methods are described for construction of sand compaction piles on land and over water. Design theories are summarized for the utilization of sand compaction piles at sites underlain by both cohesionless and cohesive soils. Practices and design criteria are presented.

Deep vibratory compaction of granular soils

Foundation applications, such as pile and sheet pile driving and soil compaction. These vibrators are hydraulically driven, which allows continuous variation of the vibrator frequency during operation. Moreover, modern vibrators can generate a centrifugal force of up to 4,000 kN (400 tons), and the maximum displacement amplitude can exceed 30 mm.

Vibration Potential

Although continuous compaction methods are most widely used, there is another method used to improve soil compaction called dynamic compaction . This involves using a crane to drop a heavy steel plate or ball from a height onto the ground surface repeatedly, compacting the ground in the area of the impact.
