Summary

To promote consolidation of soft ground, this method creates a vacuum in the soft ground and applies air pressure weight before sucking in pore water through the plastic board drain that is interpenetrated in soft ground.

Properties

• - Minimizes field work because of simple construction
• - Proficient in consolidation promotion and compresses construction time as it accelerates mounding speed
• - Reduces the construction time of soft ground improvement and construction costs.
• - Can construct on ground with thick sand layer.
• - No upper horizontal drainage layer (sand mat)
• - No solidification materials like cement - less pollution
