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

Embodiment Construction
[0027] like figure 1 As shown, the present invention provides a plug-in unidirectional steel-plastic geogrid, which includes five rows of horizontally connected grid bars 1 and two longitudinal frames 2, and the two frames 2 are respectively arranged on the five rows of grid bars 1 At both ends of the horizontally adjacent two grid bars 1 are connected by a connecting piece 3, and the grid bar 1 and the frame 2 are connected by a connecting piece 3.
[0028] like figure 2 As shown, the grating bar 1 is a cylindrical steel-plastic bar with a diameter of 20mm-40mm. There are two rows of opposite fan-shaped grooves 4 along the axial direction on the side of the grating bar 1, which play a limiting role when connected.
[0029] like image 3 As shown, the frame 2 is a U-shaped cylindrical steel-plastic strip whose diameter is compatible with the diameter of the grille strip 1. There are three cylindrical connecting bars 201 evenly connected to the bottom edge of the frame 2, t...

The invention discloses inserting type one-way steel and plastic geogrid which comprises multiple rows of grid strips transversely connected in series and two longitudinal borders. Every two transversely-adjacent grid strips are connected through a connecting piece. Two columns of opposite grooves are formed in the peripheral side of each grid strip in the axial direction of the grid strip. Each connecting piece comprises a connecting block, and a through hole is formed in the middle portion of each connecting block and matched with the corresponding grid strips; a rectangular groove communicating with the corresponding through hole is formed in the center of each connecting block, two opposite springs are arranged on the upper inner wall and the lower inner wall of each rectangular groove, the other end of each spring is connected with a buckle, and each buckle is matched with the corresponding groove. An inserting manner is adopted for fixing the geogrid, every two adjacent grid strips are connected through one connecting piece, production and installation are convenient, the connecting pieces can be additionally arranged in middle portions of the grid strips, and the overall strength is improved; and meanwhile the length of the whole geogrid can be increased at will by increasing the grid strips, 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 one-way 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 prior art ...
