Title: (EN) CONTROLLED SYSTEM FOR THE DENSIFICATION OF WEAK SOILS
Abstract:
(EN) 593789 Disclosed is a method of imparting strength to earth in support of a ground surface. The method comprises placing a bag in the earth under the ground surface, the bag having a first end oriented towards the ground surface, a second end opposite the first end, and a hourglass cross sectional contour from the first end to the second end that includes at least two wedge portions extendable laterally into surrounding earth located above and below the wedge portion when the bag is filled. Expandable polymeric resin is injected into the bag to at least partially fill the bag to compress earth around the bag. The wedge portion is defined annularly around an axis of the bag and is oriented in a first strata of earth over a second strata, the first strata of earth being weaker than the second strata.
