Technical Field

[0001] The utility model relates to the field of geocells, in particular to a foldable geocell. Background Art

[0002] In the fields of civil engineering, soil and water conservation, and ecological restoration, geocells, as an important engineering material, are widely used in soil reinforcement, vegetation restoration, slope stabilization and other projects. Traditional geocells are usually composed of a single or multiple cell pieces, and the cell pieces are connected to each other through connecting nodes to form an overall structure. However, in actual application, the cell node is the key part connecting the cell pieces, and its firmness is directly related to the stability and service life of the entire geocell.

[0003] Traditional cell node connection methods often have problems such as loose connection, easy fracture or falling off under stress. Especially in the face of complex terrain, harsh environment or long-term external force, damage to the node often becomes the cause of failure of the entire geocell structure. Therefore, how to improve the connection firmness of the cell node and ensure its stability and durability under various conditions of use has become a key issue that needs to be solved in the current development of geocell technology. Utility Model Content
