[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 to Figure 5 In an embodiment of the utility model, a geogrid fixing component includes a grid 1, a connecting piece 2 is integrally formed at the top of the node of the grid 1, a circular hole 3 is opened inside the connecting piece 2 and penetrates to the bottom of the grid 1, a fixing component connected to the ground is inserted into the inner wall of the circular hole 3, and an ejection component is arranged on the inner wall of the fixing component; the fixing component is used to firmly connect the grid 1 to the ground; the ejection component further reinforces the fixing component inserted into the ground, and the further reinforced fixing component can improve the connection force with the ground.

[0025] In this embodiment: after the grille 1 is laid, the fixing assembly is used to penetrate the circular hole 3, and the fixing assembly is completely nailed into the ground. The fixing assembly now defines the position of the grille 1, and then the reinforcing rod 8 is inserted into the through hole 6 by a tool. During the insertion of the reinforcing rod 8, the reinforcing rod 8 squeezes the ejection assembly, and the compressed ejection assembly moves outward, increasing the contact area with the ground, thereby improving the connection force, and further reducing the probability of the fixing assembly loosening and coming loose from the ground.

[0026] Please refer to Figure 1 , Figure 2 and Figure 3 The fixing assembly includes a rod 4 inserted into the inner wall of the circular hole 3 and nailed into the ground. The bottom end of the rod 4 is a conical structure, and a connecting head 5 is integrally formed at the top end of the rod 4. The rod 4 nailed into the ground drives the bottom end surface of the connecting head 5 to contact the top end surface of the connecting piece 2; a through hole 6 is opened at the top end of the connecting head 5 and penetrates into the inner cavity of the rod 4.

[0027] In this embodiment: after the grille 1 is laid, the rod 4 is nailed into the ground through the circular hole 3 until the bottom end of the connecting head 5 is effectively pressed against the top end of the connecting piece 2. At this time, the rod 4 is completely nailed into the ground, and the position of the grille 1 is limited.

[0028] Please refer to Figure 2 and Figure 3 Four grooves are provided in the middle section of the insertion rod 4, and the grooves penetrate the insertion rod 4.

[0029] In this embodiment: the groove is used to accommodate the reinforcement block 7. In the initial state, the outer wall of the reinforcement block 7 is flush with the outer wall of the insertion rod 4, avoiding the problem of increased insertion resistance when the insertion rod 4 is inserted.

[0030] Please refer to Figure 3 , Figure 4 and Figure 5 The ejection assembly includes a reinforcement block 7 axially slidably connected to the inside of the groove, the top and bottom ends of the reinforcement block 7 are formed with sliders 10, and the top and bottom ends of the groove are provided with slide grooves 9 for the sliders 10 to slide; the inner walls of the four reinforcement blocks 7 are formed with inwardly protruding top blocks 12, and the top surface of the top block 12 is formed with a pressure surface 13, the inner wall of the through hole 6 is inserted with a reinforcement rod 8, and the bottom end of the reinforcement rod 8 is formed with a vertebral body 11, and the conical surface of the vertebral body 11 coincides with the pressure surface 13.

[0031] In this embodiment: after the fixing assembly is plugged in, the reinforcing rod 8 is first inserted into the through hole 6. At this time, the vertebral body 11 is restricted by the four initial pressure surfaces 13. Then, a tool (such as a hammer) is used to hit the top end of the reinforcing rod 8. The reinforcing rod 8 is forced to continue to move downward along the through hole 6. At this time, the vertebral body 11 squeezes the four pressure surfaces 13. The squeezed pressure surfaces 13 push the four top blocks 12 to move synchronously outward. The moving top blocks 12 squeeze the surrounding soil until the reinforcing rod 8 is fully inserted. The top blocks 12 moving outward increase the contact area between the fixing assembly and the ground, thereby further improving the fixing effect of the fixing assembly.

[0032] During the movement of the top block 12 , the top block 12 drives the sliding block 10 to move along the sliding groove 9 .

[0033] Please refer to Figure 3 , both ends of the chute 9 are closed structures.

[0034] In this embodiment, this arrangement can prevent the sliding block 10 from falling off from the sliding groove 9, thereby preventing the top block 12 from falling off.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
