[0002] Geocell is a three-dimensional mesh cell structure formed by connecting sheets in a certain way. It is a civil engineering material with facade reinforcement effect and effective overall lateral confinement effect. It is flexible and can be folded during transportation. During construction, it can be stretched into a mesh and filled with loose materials such as soil, gravel, concrete, etc. to form a structure with strong lateral restriction and high rigidity. It is mainly used to reinforce the roadbed of railways and highways, protect slopes, prevent sand and fix sand, and build retaining walls.

[0003] Existing geocells are mainly fixed and connected by welding, riveting, welding and other methods. These connection methods will cause a certain degree of damage to the sheet, resulting in poor tensile strength of the cell. After the cell sheet is stretched, the connection is prone to breakage, which seriously affects the normal use of the cell sheet. Utility Model Content

[0031] In order to facilitate the matching of the protrusion 20 and the groove 30, the connector 2 is divided into two connecting plates 40 that are spliced ​​together. A half groove 41 is provided on the connecting side of the connecting plate 40 at the position corresponding to the square block 21 of the protrusion 1.
