Preferably, the connection part of the transverse grating and the longitudinal grating with the connecting block is provided with reinforcing ribs, and the reinforcing ribs are respectively connected with the connecting block and the transverse grating or the longitudinal grating through second bolts.
By adopting the technical scheme, the connecting block and the transverse grid or the longitudinal grid are connected through the second screw by the reinforcing ribs, so that the connection strength of the transverse grid or the longitudinal grid and the connecting block is enhanced, the possibility that the transverse grid or the longitudinal grid is separated from the connecting block is prevented, and the bending strength of the geogrid is stronger.
Preferably, limit grooves are formed in two ends of the flat surfaces of the transverse grating and the longitudinal grating, and barbs are fixedly connected above the connecting grooves of the connecting blocks.
By adopting the technical scheme, the barb is triangle-shaped, and when the grid inserted the connecting block, can slide in along the triangle inclined plane, after the grid got into the spread groove, barb and spacing groove cooperation for the grid card has further strengthened joint strength in the connecting block, and simultaneously, the barb adopts rubber material to make, guarantees the mobility of barb, guarantees that the grid can insert in the connecting block smoothly.
Preferably, the connecting groove is double-T-shaped.
By adopting the technical scheme, the double T-shaped connecting grooves correspond to the double T shapes of the transverse grating and the longitudinal grating, so that the connection of the transverse grating and the longitudinal grating is more fit.
The beneficial effects are that: 1. the transverse grid and the longitudinal grid of the geogrid are both double-T-shaped, and compared with a common plate, the double-T-shaped grid has stronger bending resistance, so that the geogrid is longer in effective duration and is not easy to damage.
2. The grids are connected by connecting blocks, and parts of the whole geogrid can be assembled after being transported to a construction site, so that the geogrid is more convenient to transport.
3. The connecting block and the grid side are connected by the reinforcing ribs, so that the connection strength between the grid and the connecting block is further enhanced.
