Vacuum preloading (consolidation) method for improving fine grain soil. This method utilizes atmosphere pressure as a temporary surcharge for improving fine grain soft soil.

The basic idea of vacuum preloading method is applying a vacuum suction into an isolated soil mass to reduce the atmosphere pressure and pore water pressure in the soil, resulting soil consolidation and effective stress enhance without change the total stress.

Basically, whole vacuum preloading system consists of drainage system, isolation system and vacuum pumps. Once generated in vacuum pumps, vacuum suction rapidly spreads into soils along drainage system, reducing atmosphere and pore water pressure and forming pressure difference between vertical drains and pore water in soils. This pressure difference cause the pore water flows toward vertical drain which means soil consolidation happens. Vacuum suction keeps taking out water and air and accelerating soil consolidation.

Drainage system is an interconnected network of PVD, horizontal filter pipes and sand layer, forming a complete path for spreading of vacuum suction and water flow.

Isolation system is used to cutoff leakage of water & air below it. It consists of geomembrane, the soft clay itself and cutoff wall if necessary.

Also known as Wick Drains, Prefabricated Vertical Drains (PVDs) are composed of a durable plastic core (usually polypropylene) wrapped around a synthetic geotextile (i.e. a filter jacket) to facilitate the movement of water through slow-draining soils.
The principal of installation of the vertical drainage is based on the insertion of a steel mandrel into the ground with a drain inside. The drain extension at the bottom of the mandrel can be connected to an anchor plate or stick to help the anchoring of the drain. Automatic anchoring systems are also available keeping the drain at depth during retraction of the mandrel. After the mandrel has reached the surface, the drain is cut and a new anchor plate is connected to the bottom of the next drain. The mandrel is pushed into and retracted from the ground through a system of cylinders and winches, which in turn are propelled by the excavators’ hydraulic system.
