Problems solved by technology
[0003] However, the current grids have a common defect, that is, the height of the ribs is limited, most of which are only 1-3mm. When the tensile strength is high, it is difficult for the grid to restrain the soil. In the engineering of tensile strength, it is difficult to bring out the high-strength characteristics, and it loses the meaning of high-strength

Embodiment Construction
[0020] In order to have a clearer understanding of the technical features, purposes, effects and embodiments of the present invention, specific implementations of the present invention will now be described in conjunction with the accompanying drawings.
[0021] Such as Figure 1 to Figure 3 As shown, a high grid with joints formed by injection molding fusion, including horizontal strips 1, vertical strips 2 and injection molded body 4, a series of rectangular nets are formed by the crossing of multiple horizontal strips 1 and longitudinal strips 2 Grid structure, a slit 31 is set every other grid interval on the vertical and horizontal strips, and a row of holes 32 are arranged on both sides of each slit 31, and the slits 31 at the corresponding positions of the vertical and horizontal strips are inserted into each other , nodes 3 are formed at the joints, and an injection molded body 4 is arranged around each node 3 . The present invention is specifically operated as follow...

The invention discloses a high geogrid with joints formed through injection molding and fusion welding. The high geogrid comprises horizontal strips, longitudinal strips and injection molding bodies, wherein the longitudinal strips and the horizontal strips are intersected to form a net structure, kerfs are formed in each of the longitudinal strips and the horizontal strips at an interval of mesh spacing, holes are formed in one side or two sides of each kerf, the kerfs in the corresponding positions of the longitudinal strips and the horizontal strips are in opposite inserting connection, joints are formed in the inserting connection positions, and the injection molding bodies are arranged around the joints. By means of the structure, the strength of the joints of the geogrid cannot be weakened while the height of the geogrid is increased; the geogrid is high enough, the overall strength of the geogrid is enhanced, soil mass can be better wrapped and constrained, and the reinforcement function on the soil mass is remarkably improved.
Description
technical field [0001] The invention relates to the technical field of geotechnical grids, in particular to a high grid whose nodes are welded by injection molding. Background technique [0002] As a new type of civil engineering structure, geogrid is an indispensable device in the current basic construction. There are many types of products, the most typical ones are plastic integral tensile grid, plastic strip welded grid and steel-plastic composite Welded grille can be divided into one-way grille, two-way grille, three-way grille, four-way grille, etc. according to the direction of force. These grids have their own advantages. They are mainly used as reinforcement materials. They are used in projects such as soft soil foundation reinforcement, reinforced soil retaining walls, and slope protection because of their high tensile strength and small elongation. , making it play an important role in controlling soil deformation. [0003] However, the current grids have a comm...
