[0002] A geogrid is a main geosynthetic material. Compared with other geosynthetics, it has unique properties and functions. It is commonly used as a reinforcement material for reinforced soil structures or a reinforcement material for composite materials. A polymer mesh material with a square or rectangular shape is formed by stretching the geogrid;

[0003] Application No. CN202320484319.0 discloses a double-way reinforced geogrid. The inner side wall of the connecting groove is fixedly connected with a threaded block. The bottom end of the screw block is fixedly connected with a threaded rod. The bottom end of the threaded rod is fixedly connected with a connecting column. The two sides of the connecting column are rotatably connected with a limiting rod through a rotating shaft. The top end of the limiting rod is in contact with the bottom end of the longitudinal grid strip.

On the outer walls of both sides of the first grid body and the second grid body, support plates are fixedly connected. Inside the first grid body and the second grid body, there are several groups of transverse grid bars. Both ends of several groups of the transverse grid bars are fixedly connected to the support plates. Outside the transverse grid bars, there are several groups of longitudinal grid bars. The longitudinal grid bars and the transverse grid bars are connected through a locking mechanism. The locking mechanism includes a threaded column inserted between the longitudinal grid bars and the transverse grid bars. On both the longitudinal grid bars and the transverse grid bars, there are screw holes corresponding to the threaded column. One end of the threaded column is fixedly connected with a first screw head. There is a cavity opened on the threaded column. On the screw head, there is a slotted groove. Inside the slotted groove, there is a second screw head. The second screw head is fixedly connected with a threaded rod. One end of the threaded rod is rotatably connected to the inner wall of the threaded column. On the side wall of the threaded rod located inside the threaded column, a pressing block is threadedly sleeved. On both sides of the pressing block, there are wedge-shaped blocks. One side of the wedge-shaped block is fixedly connected with a limiting block. The limiting block penetrates through the threaded column and extends outwards. Between both ends of the wedge-shaped block and the inner wall of the threaded column, elastic mechanisms are fixedly connected.

[0007] Preferably, the first screw head is a hexagonal screw head.

[0008] Preferably, the second screw head is a cross-slot screw head.

[0009] Preferably, both ends of the pressing block are arranged in an arc-shaped structure.

[0010] Preferably, the elastic mechanism is a spring.

[0011] Preferably, the wedge-shaped block is arranged in a structure with a narrow upper part and a wide lower part.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] For this bidirectional reinforced geogrid, the transverse grid bars are installed and supported by the support plates. The threaded column is screwed into the screw holes on the transverse grid bars and the longitudinal grid bars. Subsequently, the second screw head is rotated to drive the threaded rod to rotate in the cavity opened on the threaded column. When the threaded rod rotates, the pressing block threadedly sleeved thereon will move accordingly to press the wedge-shaped block. At this time, the wedge-shaped block will move under the extrusion of the pressing block to push the limiting block to move. At this time, the limiting block will move out of the threaded column. The transverse grid bars are used to provide limitation for the limiting block. The utility model improves the installation stability of the grid bars and avoids loosening by setting a limiting mechanism on the locking part, and the whole can be easily disassembled and assembled for use.

[0020] Please refer to Figure 1-2, an embodiment provided by the present utility model: a double-sided reinforced geogrid, comprising a first grid body 1 and a second grid body 2. A filling mesh plate 3 is fixedly connected to the opposite sides of the first grid body 1 and the second grid body 2. Support plates 4 are fixedly connected to the outer walls on both sides of the first grid body 1 and the second grid body 2. A number of groups of transverse grid bars 5 are provided inside the first grid body 1 and the second grid body 2. Both ends of the number of groups of transverse grid bars 5 are fixedly connected to the support plates 4. A number of groups of longitudinal grid bars 6 are arranged outside the transverse grid bars 5. The longitudinal grid bars 6 and the transverse grid bars 5 are connected by a locking mechanism. The locking mechanism includes a threaded column 7 inserted between the longitudinal grid bars 6 and the transverse grid bars 5. Threaded holes corresponding to the threaded column 7 are provided on both the longitudinal grid bars 6 and the transverse grid bars 5. One end of the threaded column 7 is fixedly connected to a first screw head 8. A cavity is provided on the threaded column 7. A slotted hole is provided on the screw head. A second screw head 9 is provided in the slotted hole. A threaded rod 10 is fixedly connected to the second screw head 9. One end of the threaded rod 10 is rotatably connected to the inner wall of the threaded column 7. A pressing block 11 is threadedly sleeved on the side wall of the threaded rod 10 located inside the threaded column 7. Wedge blocks 12 are provided on both sides of the pressing block 11. One side of the wedge block 12 is fixedly connected to a limiting block 13. The limiting block 13 penetrates through the threaded column 7 and extends outwards. Elastic mechanisms 14 are fixedly connected between both ends of the wedge block 12 and the inner wall of the threaded column 7. Specifically, the threaded column 7 is screwed into the threaded holes on the transverse grid bars 5 and the longitudinal grid bars 6. Then the second screw head 9 is rotated to drive the threaded rod 10 to rotate in the cavity on the threaded column 7. When the threaded rod 10 rotates, the pressing block 11 threadedly sleeved thereon will move accordingly to press the wedge block 12. At this time, the wedge block 12 moves under the extrusion of the pressing block 11 to push the limiting block 13 to move. At this time, the limiting block 13 will move outside the threaded column 7, and the transverse grid bar 5 is used to provide a limit for the limiting block 13.

[0021] In this embodiment, the first screw head 8 is a hexagonal screw head; the second screw head 9 is a cross-slot screw head; both ends of the pressing block 11 are arranged in an arc structure to reduce the frictional resistance with the wedge block 12; the elastic mechanism 14 is a spring, with high resilience and can realize the rebound of the limiting block 13; the wedge block 12 is arranged in an upper-narrow and lower-wide structure.

[0022] Working principle: First, the support plate 4 installs and supports the transverse grid bars 5. The threaded column 7 is screwed into the threaded holes on the transverse grid bars 5 and the longitudinal grid bars 6. Then the second screw head 9 is rotated to drive the threaded rod 10 to rotate in the cavity on the threaded column 7. When the threaded rod 10 rotates, the pressing block 11 threadedly sleeved thereon will move accordingly to press the wedge block 12. The wedge block 12 maintains downward movement through the limit of the cavity. At this time, the wedge block 12 moves under the extrusion of the pressing block 11 to push the limiting block 13 to move. At this time, the limiting block 13 will move outside the threaded column 7, and the transverse grid bar 5 is used to provide a limit for the limiting block 13.
