Description

Technical Field

[0001] The utility model relates to the technical field of geogrids for infrastructure construction, in particular to a double-layer grid connector and a reinforced slope geogrid using the double-layer grid connector. Background Art

[0002] Geogrid is a major geosynthetic material, often used as reinforcement for reinforced soil structures or reinforcement for composite materials.

[0003] Most of the existing geogrids are grid structures composed of radial ribs and transverse ribs, and are used in a single layer, resulting in limited overall reinforcement performance of the geogrid. The application document with application number CN201921647926.4 in the patent library discloses a reinforced double-layer geogrid, which includes an upper grid and a lower grid. The upper grid and the lower grid are fixed on both sides by connecting plates and screws, and the middle is fixed by plastic conical top sleeves that can be nested with each other. This setting method requires setting connecting plates and plastic conical top sleeves on the upper grid and the lower grid respectively. The structure for connection (connecting plates and plastic conical top sleeves) is relatively complicated to set up, and the matching connection of the double-layer grid is also more troublesome.

The structure of the connecting member is described in detail below.

[0027] In this embodiment, combined with Figure 1 and Figure 2 The first fixing seat includes a horizontally arranged rectangular bottom plate 1, and four first grooves arranged in a "well" shape are opened on the lower side of the bottom plate 1, and both ends of the four first grooves penetrate to the outer edge of the bottom plate 1, and the four first grooves are respectively arranged parallel to or perpendicular to the outer edge of the bottom plate 1, wherein the two adjacent longitudinal ribs of the first grille 8 and the two transverse ribs intersecting the two longitudinal ribs can be respectively inserted into the four first grooves.

[0028] On the basis of the above structure, a cover plate is further provided on the lower side of the bottom plate 1 , and the cover plate is a square first cover plate 2 , through which the first grille 8 can be pressed and fixed in the first groove.

[0029] As a preferred embodiment, the first cover plate 2 is connected to the base plate 1 by a first bolt 3, and the first bolt 3 is arranged through the intersection of two adjacent first grooves. On the basis of this structure, while the first cover plate 2 is connected to the base plate 1 by the first bolt 3, the first bolt 3 can also pass through the intersection of the longitudinal ribs and the transverse ribs of the first grille 8 to further fix the first grille 8 in the first groove, so that the connection between the first grille 8 and the first fixing seat can be more firm and reliable.

[0030] As a further preferred embodiment, in order to further improve the fixing effect of the first bolts 3 on the first grille 8, four first bolts 3 are provided at four intersections of the four first grooves.
