Abstract:
1. A method for supporting a structure, comprising a cohesion pillar located below said structure in a surrounding ground, wherein said cohesion pillar transfers a structure load via shaft adhesion to said surrounding ground, wherein said method further comprises determining a shearing strength of said surrounding ground, wherein said cohesion pillar comprises an expansion element made from a flexible material, wherein said expansion element is filled via an injecting pipe that injects polymer into said expansion element, wherein said polymer undergoes a chemical reaction within said expansion element resulting in adhesion between said expansion element and said surrounding ground, and wherein said polymer absorbs water from said surrounding ground improving adhesion between said surrounding ground and said cohesion pillar, wherein said method further comprises determining a water absorption amount of said polymer based on said shearing strength of said surrounding ground.
