Description

Technical Field

[0001] The utility model belongs to the technical field of geogrids, and in particular relates to a geogrid with a negative Poisson's ratio effect. Background Art

[0002] Geogrid is a main geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is often used as reinforcement material for reinforced soil structures or reinforcement material for composite materials. In order to ensure the strength of geogrids, some geogrids often apply the principle of negative Poisson's ratio effect during the design and production process, and set them into a shape that is convenient for the negative Poisson's ratio effect to enhance the strength of the geogrid.

[0003] During the use of geogrids, due to their large laying area, multiple geogrids need to be spliced ​​together for use. The connectivity of traditional geogrids is poor when spliced ​​together, making it impossible to connect the geogrids together and easy to separate them, resulting in them being unable to function. In addition, traditional geogrids are generally connected to the ground through ordinary anchor rods, and ordinary anchor rods have weak grip and are easy to fall off, causing the grid to slide. In order to solve the above problems, a geogrid with a negative Poisson's ratio effect is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that during the use of geogrids, due to the large laying area, multiple geogrids need to be spliced ​​together for use, and the traditional geogrids have poor connectivity when spliced ​​together, making it impossible to connect the geogrids together and easily separate them, resulting in them being unable to function, and the traditional geogrids are generally connected to the ground through ordinary anchor rods, which have weak grip and are easy to fall off, thereby causing the grid to slide. A geogrid with a negative Poisson's ratio effect is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a geogrid with negative Poisson's ratio effect, comprising a first grid, a second grid is arranged on one side of the first grid, a connecting component is arranged between the first grid and the second grid, and a fixing component is arranged in both the first grid and the second grid;

[0006] The connecting assembly comprises a bottom plate, a first baffle is fixedly connected to the top surface of the bottom plate, an inner side of the first baffle is slidably connected to the first grille, and a second baffle is slidably connected to the outer side of the first baffle.

[0007] As a further description of the above technical solution:

[0008] The top of the second baffle is fixedly connected to the top plate, the second baffle is slidably connected to the bottom plate through a groove provided on the top surface of the bottom plate, and the bottom plate is slidably connected to the plug plate through a groove provided therein.

[0009] As a further description of the above technical solution:

[0010] The top surface of the plug board is fixedly connected with a connecting block, the top of the connecting block is fixedly connected with a sliding plate, and the plug board is slidably connected with the second baffle through a groove provided on the second baffle.

[0011] As a further description of the above technical solution:

[0012] The fixing assembly comprises a mounting seat, and a mounting plate is fixedly connected to one side of the mounting seat.

[0013] As a further description of the above technical solution:

[0014] The mounting plate is slidably connected to an anchor rod through a through hole provided therein, and a top cap is fixedly connected to the top end of the anchor rod.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the anchor rod is fixedly connected with a spiral blade, and the mounting seat is slidably connected with the first grille through a groove provided therein.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] 1. In the utility model, by arranging a second baffle inside, when connecting two grids, the first grid and the second grid are aligned, and the connection between them is placed between the first baffles, and then the second baffle is inserted into the outside of the first baffle, and the slide plate is pushed so that one end of the insert plate extends into the second baffle to fix it. Through this design, the connection between the first grid and the second grid is realized, and the connection between the two can be strengthened, so that by connecting multiple geogrids together, their strength is improved, and it can be prevented from breaking at the connection, causing the geogrid to rupture and thus causing its overall strength to decrease.

[0019] 2. In the utility model, a spiral blade is arranged inside, and after the geogrid is laid, it is connected to the geogrid through the groove opened in the mounting seat, and the spiral blade is driven to rotate by rotating the top cap to screw it into the ground. Through this design, the connection between the anchor rod and the ground is enhanced, thereby reducing the possibility of the anchor rod being pulled out of the ground, thereby tightly fixing the geogrid on the ground and avoiding the situation where the geogrid slides due to its falling off and affects its function.
