[0002] Geogrids, as a very important geosynthetics, have been widely used in geotechnical engineering in my country. Traditionally, geogrids are divided into two categories: unidirectional geogrids and bidirectional geogrids. Unidirectional geogrids are generally used for structural support, while bidirectional geogrids are mainly used for foundation treatment and control of uneven settlement. Three-way geogrids are based on the original bidirectional geogrids and have optimized their structural type. Their performance in foundation reinforcement is far superior to that of traditional bidirectional geogrids. As a new type of geogrid, it has also been widely used in engineering in recent years due to its excellent engineering properties.

[0003] However, since the geogrid needs to be connected when it is laid, the traditional connection method is bundling or overlapping. The strength of the geogrid connected in this way is not high at the connection point and it is easy to fall off during use. Therefore, the present application proposes a three-way stable geogrid that is easy to connect. Utility Model Content
