The unidirectional stretching grid is only stretched along the length direction of the sheet, while the bidirectional stretching grid is made by continuing to stretch the unidirectional stretching grid in a direction perpendicular to its length. Therefore, the plastic geogrid device is an important civil engineering component. In the existing plastic geogrid devices, the transverse grid bars and the longitudinal grid bars are formed by outward stretching through the integral nodes, and the unidirectional blanks are transported through the integral nodes to form the transverse grid bars and the longitudinal grid bars. Due to the material limitation of the polymer sheet, the stretching length of the transverse grid bars and the longitudinal grid bars is limited, which affects the manufacturing effect of the plastic geogrid.

[0003] The utility model has the technical feature of making the outwardly stretched transverse grid bars and longitudinal grid bars conveyed in a non-unidirectional billet conveying state, and has effectively explored and studied the technical problem of the billet conveying in which the transverse grid bars and longitudinal grid bars are formed by outwardly stretching the integral nodes and the transverse grid bars and longitudinal grid bars are conveyed in a unidirectional manner.
