WANG XUEWEN / DU LIQI / HOU LIJUN / JIN WEI

The invention discloses a large-particle-size rock-soil foundation reinforced geogrid. The large-particle-size rock-soil foundation reinforced geogrid comprises longitudinal ribs formed through longitudinal stretching and transverse ribs formed through transverse stretching, wherein the end parts of the transverse ribs and the end parts of the longitudinal ribs are connected in a crossed mode to form rectangular grids; the plurality of rectangular grids are regularly arranged in the longitudinal direction and the transverse direction; the length of each transverse rib is 20 to 50 mm; and the length of each longitudinal rib is 200 to 500 mm. Compared with an existing geogrid with the conventional pore diameter, the large-particle-size rock-soil foundation reinforced geogrid has the advantages that the large-pore-diameter geogrid and a large-particle filler achieve a better meshing and embedding effect, and on the premise of ensuring the stability of a retaining wall slope, the strength and the consumption of geogrid products can be reduced; local materials can be used; and damage to the environment caused by outward transportation of filling soil is avoided. In addition, molecules are oriented on the transverse ribs after the transverse ribs are transversely stretched, so that the grid achieves higher strength and toughness in the transverse direction.

本发明公开了一种大粒径岩土基础加筋土工格栅，该加筋土工格栅包括经纵向拉伸形成的纵向肋条和经横向拉伸形成的横向肋条，所述横向肋条端部和所述纵向肋条端部交叉连接形成矩形栅格，若干个所述矩形栅格沿纵向方向和横向方向规则排列；所述横向肋条的长度为20‑50mm，所述纵向肋条的长度为200‑500mm。该大粒径岩土基础加筋土工格栅，与现有格栅的孔径相比，大孔径格栅与颗粒较大的填料具有更好的咬合嵌固的效果，在保证挡墙边坡稳定的前提下，可以减少土工格栅产品的强度和使用数量；可以实现就地取材，避免了外运填土对环境的破坏。此外，经过横向拉伸的横向肋条，使分子在横向肋条上取向，使格栅横向达到较高强度和韧性。
