Geogrids are mainly used on highways for soft foundation treatment, roadbed reinforcement, slope protection, bridge abutment reinforcement, wing walls, retaining walls, isolation and reinforced soil engineering. Using geogrids on railways can prevent the railway on soft soil foundation from premature settlement and damage.

[0004] The hexagonal short grids that make up the grille in this scheme are simple hexagonal structures with poor tensile strength, and are prone to deformation in the plane direction of the hexagonal short grids. The structural stability is poor, which seriously affects the function of the grille. Utility Model Content

The combined area includes three triangles. The arrangement of the triangles and trapezoids enhances the tensile strength of the grille, and in particular, the arrangement of the triangles enhances the strength of the hexagonal unit and the grille.

[0011] Preferably, the area of ​​the rectangular unit is 0.3-0.4 times the area of ​​the hexagonal unit.

[0012] This preferred solution reduces the size of the through hole in the middle of the hexagonal unit by setting the area of ​​the rectangular unit, thereby being able to block sand and gravel with smaller particle sizes.

[0013] Preferably, the hexagonal units are arranged in sequence in the transverse direction to form a transverse group, and a number of rhombus units arranged in sequence in the transverse direction are formed between two adjacent transverse groups. The rhombus units are provided with transverse ribs extending in the transverse direction and arranged in line with the diagonal lines of the rhombus.

[0014] This preferred solution facilitates the connection of the corresponding four hexagonal units through the provision of transverse ribs, thereby further improving the overall tensile strength of the grid.
