A plug-in two-way steel-plastic geogrid

Abstract

A plug-in type bidirectional steel plastic geogrid comprises a plurality of first grid bars and a plurality of second grid bars, wherein the first grid bars are perpendicular to the second grid bars. Each first grid bar is connected with the corresponding second grid bar intersecting with the first grid bar through a connecting piece; a column of plug-in holes matched with the second grid bars are formed in the middle of each first grid bar in the axial direction; each connecting piece comprises a rectangular connecting block; and a first through hole and a second through hole interpenetrating to the first through hole are formed in the middle of each connecting block, each first through hole is matched with the corresponding first grid bar, and each second through hole is matched with the corresponding second grid bar. According to the plug-in type bidirectional steel plastic geogrid, fixing is achieved through a plug-in method, and production and installation are convenient; further, the distance between the grid bars can be freely adjusted by arranging additional first grid bars, second grid bars and connecting pieces freely in the middle of the geogrid, and the overall intensity is high; and meanwhile, the length and width of the whole geogrid can be expanded freely by arranging additional first grid bars, second grid bars and connecting pieces at the edges of the geogrid, and the expansibility is high.

Description

technical field [0001] The invention belongs to the technical field of geogrids, and relates to a steel-plastic geogrid, in particular to a plug-in bidirectional steel-plastic geogrid. Background technique [0002] Geogrid is a main geosynthetic material. Compared with other geosynthetic materials, it has unique performance and efficacy. Geogrid is often used as reinforcement of reinforced soil structure or reinforcement of composite material. Geogrid It is divided into four categories: plastic geogrid, steel-plastic geogrid, glass fiber geogrid and polyester warp-knitted polyester geogrid. [0003] The steel-plastic geogrid is made of high-strength steel wire (or other fibers), which is specially treated, and polyethylene (PE), and other additives are added to make it a composite high-strength tensile strip through extrusion, and the surface has rough pressure. pattern, it is a high-strength reinforced geotechnical belt. [0004] The steel-plastic geogrid used in the prio...

AI Technical Summary

Problems solved by technology

[0004] The steel-plastic geogrid used in the prior art is made of a single belt, which is arranged vertically and horizontally at a certain interval or sandwiched, and is formed by welding its junctions with a special strengthening bonding fusion welding technology, and its structural expansion is relatively large. Poor, and the strength of the structural welding is also low, due to the size of its own structure has a certain area limit, can not form an integral geogrid continuously
