[0002] The geocell is a three-dimensional mesh cell structure, which is flexible and can be folded for transportation. During construction, the geocell can be stretched into a mesh and filled with loose materials such as soil, gravel and concrete to form a structure with strong lateral restraint and large rigidity. The geocell is mainly used for reinforcing roadbeds of railways and highways, protecting slopes, preventing sand and building retaining walls. The geocell is currently a commonly used method for building retaining walls.

[0003] The existing geocell is mainly fixed and connected through welding, riveting and injection molding. During work, the connecting part of the geocell sheet is prone to falling off and separating, and the structural stability is poor. For example, in the geocell connecting piece and geocell of patent CN 218147581U, a concave piece, a convex piece, a clamping groove, a clamping column and an arc-shaped spring piece are arranged, and the shapes of the clamping groove and the clamping column are the same. During use, the concave piece is slid upward from the bottom. During the upward sliding of the concave piece, the arc-shaped spring piece is extruded, thereby generating a reverse force, and the structural stability of the concave piece and the convex piece during connection is enhanced. However, with the updating of civil engineering cells, the stability no longer meets the requirements of existing civil engineering cells.
