The invention provides a quaxial geogrid comprising a plurality of nodes and a plurality of ribs, the nodes and the ribs are connected to form a plurality of rectangular units, each of the rectangular units comprises four first nodes located at four vertexes of a rectangle, and a second node located at a diagonal intersection of the rectangle, wherein each of the rectangular units further comprises a first rib located in the direction of a side of the rectangle to connect two adjacent first nodes, a third node located at a midpoint of each side of the rectangle, a second rib located at a diagonal of the rectangle, and a third rib passing through the second node and connecting the third nodes; wherein the thickness of each of the nodes is larger than the thickness of each of the ribs. The invention increases the frictional force between the geogrid and the filler, and improves the shear resistance of the geogrid to the filler. |
