It uses the principle of three-dimensional confinement and is suitable for foundation reinforcement, cushion and surface protection. It is a three-dimensional structure. By changing its depth and hole type combination, rigid or semi-elastic plates can be obtained, which can greatly improve soft and loose filling. load-carrying capacity of the material. In civil engineering, geocells of different specifications can form cushions with different cohesion, different reinforcement strengths, and different thicknesses with soil, sand, stone and other fillers.
