[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. Geogrid has high strength, low creep, adaptability to various environmental soils, and can effectively improve the locking and biting effect of the reinforced bearing surface, greatly enhance the bearing capacity of the foundation, effectively restrain the lateral displacement of the soil, and enhance the stability of the foundation.

[0003] Traditional geogrids are often laid as a whole piece during use. During use, when a part of it is damaged, it cannot be replaced separately, so that the damaged part cannot be repaired in time, resulting in its function being reduced. In addition, the geogrids often laid are single-layer, and the effect they play is low and cannot effectively play the corresponding role. In order to solve the above problems, a reinforced double-layer geogrid is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to propose a reinforced double-layer geogrid to solve the problem that traditional geogrids are often laid as a whole piece during use, and when a certain part is damaged during use, it cannot be replaced separately, so that the damaged part cannot be repaired in time, thereby reducing its effect, and the geogrid is often laid in a single layer, which has a low effect and cannot effectively play a corresponding role.

[0012] As a further description of the above technical solution:

[0013] The fixing assembly includes a mounting post, which is slidably connected to the connecting sleeve via a groove provided in the connecting sleeve, the mounting post is fixedly connected to the upper grille, a sliding tongue is slidably connected in the mounting post, and the sliding tongue is slidably connected to the connecting sleeve via a through hole provided in the connecting sleeve.

[0014] As a further description of the above technical solution:

[0015] One end of the sliding tongue is fixedly connected to a connecting column, the mounting column is slidably connected to a sliding plate through a groove provided therein, the sliding plate is slidably connected to the connecting column through the groove provided therein, the bottom end of the sliding plate is fixedly connected to a spring, and the other end of the spring is fixedly connected to the inside of the mounting column.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, by arranging a connecting rod inside, when laying the geogrid, first take out the first lower grid and lay it on the ground, take out the second lower grid and lay it on the ground and insert the connecting rod into the sliding sleeve of the first lower grid, rotate the threaded sleeve to connect it with the connecting rod, through this design, the connection between the two geogrids is achieved, and by connecting multiple grids to ensure their integrity, when a certain part is damaged, it can be easily replaced, thereby maintaining its integrity, so that the function of the geogrid is not destroyed and it can effectively play a corresponding role.

[0018] 2. In the utility model, a sliding tongue is arranged inside. When the lower grid is laid, the upper grid is laid on its surface and the mounting column is inserted into the connecting sleeve. When the sliding tongue contacts the connecting sleeve, it retracts under force. When the sliding tongue moves to the through hole opened by the connecting sleeve, the sliding tongue is driven by the spring to move and connect with the connecting sleeve, thereby connecting the upper grid with the lower grid. Through this design, the upper grid and the lower grid are fixed, thereby enhancing the role of the geogrid, effectively protecting the ground, so that the role of the geogrid can be fully exerted, reducing the occurrence of the situation where the ground cannot be effectively protected due to the low effect of the single-layer geogrid, and when the upper grid is damaged, it can be conveniently removed and replaced, thereby ensuring the integrity of the geogrid.

[0028] The specific implementation method is as follows: when laying the geogrid, first take out the first lower grid 4 and lay it on the ground, and insert the ground nails 6 into the ground, take out the second lower grid 4 and lay it on the ground, and insert the connecting rod 74 on one side of the second lower grid 4 into the sliding sleeve 1 on one side of the first lower grid 4, and insert the slider 71 into the sliding groove on one side of the second lower grid 4, and fix it by rotating the threaded sleeve 72 to connect it with the connecting rod 74;

[0029] The fixing assembly 3 includes a mounting post 31, which is slidably connected to the connecting sleeve 5 through a groove provided in the connecting sleeve 5, and the mounting post 31 is fixedly connected to the upper grille 2.
