Description

Technical Field

[0001] The utility model relates to the field of geogrids, in particular to a geogrid for construction reinforcement. Background Art

[0002] Geogrid is a major geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement for reinforced soil structures or reinforcement for composite materials. Geogrids are divided into four categories: plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp-knitted polyester geogrid.

[0003] Geogrids are often laid in the soil. Through the interlocking and interlocking effect between the grid mesh and the soil, an efficient stress transmission body is formed, so that the local load can be quickly and effectively transmitted to the soil, thereby reducing the local destructive stress. It is a more ideal reinforcing rib anti-corrosion material at this stage. In actual use, multiple geogrids are often connected together to form a reinforcement surface. Existing geogrids are often fixed by locks or bolts. This fixing method is not only troublesome, but also cannot adjust the fixed distance between the two geogrids. To this end, in view of the above-mentioned background technical problems, technical personnel in this field have proposed a geogrid for construction reinforcement. Utility Model Content
