Description

Technical Field

[0001] This utility model belongs to the field of geogrid technology, and in particular relates to three-dimensional reinforced geogrid mesh. Background Technology

[0002] Three-dimensional reinforced geogrid is a three-dimensional mesh structure geosynthetic material made from high-molecular polymers (such as polyethylene and polypropylene) through special extrusion, stretching, and welding processes. It is not only an upgrade to two-dimensional planar geogrids but also a functional composite material integrating reinforcement, protection, and ecological greening functions. Through its three-dimensional structure, it not only enhances the mechanical properties of the soil but also provides a carrier for vegetation growth, thus achieving long-term, stable, and green engineering protection effects. It is an indispensable material in modern civil engineering and environmental engineering, commonly used for the reinforcement and protection of roadbeds, embankments, and slopes. However, some geogrids have poor soil adhesion, easily shifting slightly in their designated positions during installation, preventing them from accurately fulfilling their reinforcement function. Therefore, three-dimensional reinforced geogrids are needed, employing anti-retreat and anti-detachment structures to fix the overlapping positions of the geogrid mesh, improving its soil adhesion strength and installation stability. Utility Model Content

[0003] The purpose of this invention is to provide a three-dimensional reinforced geogrid mesh, which adopts an anti-retreat and anti-detachment structure to fix the overlapping positions of the geogrid mesh, thereby improving the soil-absorbing strength of the geogrid mesh and the installation stability of the geogrid mesh, so as to solve the above-mentioned technical problems.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a three-dimensional reinforced geogrid mesh, including two geogrids: metal reinforcing bars are wound around the surface of the geogrids, a pressure plate is provided at the overlapping position of the two geogrids, and a tube is fixedly connected to both sides of the pressure plate. An anti-reverse assembly is provided in the inner cavity of the tube. The anti-reverse assembly includes an anti-reverse plate rotatably connected to the inner cavity of the tube, a threaded pin is threadedly connected to the inner cavity of the tube, and an inclined surface is provided at the top of the anti-reverse plate.

[0005] Preferably, a first rectangular groove is provided on the opposite side of the two insertion tubes, and a second rectangular groove is provided on the opposite side of the two insertion tubes.

[0006] Preferably, an elastic baffle is fixedly connected to the top of the inner cavity of the second rectangular groove, and the bottom of the elastic baffle is provided with an inclined surface.

[0007] Preferably, the top of the insertion tube has a circular groove, and a sealing plug is engaged at the top of the circular groove.

[0008] Preferably, the bottom of the cannula is provided with a tapered surface.

[0009] The beneficial effects of this utility model are: 1. This utility model uses a grid mesh and metal ribs to cover the slope. Then, with the cooperation of the insertion tube and anti-reverse component, the pressure plate is stably installed at the overlapping position of the two grid meshes, so that the grid mesh is tightly connected to the slope, thus achieving the purpose of effective elastic lifting and reliable and stable connection. 2. By using the first rectangular groove and the second rectangular groove in combination, this utility model provides a rotation space for the anti-retraction plate, so that the anti-retraction plate can rotate out from the inner cavity of the insertion tube and form a cross distribution with the insertion tube, thereby enhancing the tightness of the connection between the insertion tube and the soil in the slope. 3. The present invention uses an elastic baffle to block the backstop plate, so that the backstop plate is inserted vertically downwards during the horizontal insertion of the tube into the slope, thus ensuring a smooth insertion process.

Detailed Implementation

[0011] In the following description, embodiments of the three-dimensional reinforced geogrid mesh of the present invention will be described with reference to the accompanying drawings.

[0012] Figure 1-4This invention illustrates a three-dimensional reinforced geogrid mesh according to an embodiment of the present invention, comprising two geogrids 1: metal reinforcing bars 2 are wound around the surface of the geogrids 1, a pressure plate 3 is provided at the overlapping position of the two geogrids 1, and inserts 4 are fixedly connected to both sides of the pressure plate 3. A circular groove 7 is provided at the top of the insert 4, and a sealing plug 8 is engaged at the top of the circular groove 7. A sloping conical surface 9 is provided at the bottom of the insert 4, and a backstop assembly 5 is provided in the inner cavity of the insert 4. The backstop assembly 5 includes a backstop plate 51 rotatably connected to the inner cavity of the insert 4, a threaded pin 52 is threadedly connected to the inner cavity of the insert 4, and a sloping surface 53 is provided at the top of the backstop plate 51. A first [missing information] is provided on the opposite side of the two inserts 4. The rectangular groove 54 has a second rectangular groove 55 on each side of the two insertion tubes 4. The cooperation of the first rectangular groove 54 and the second rectangular groove 55 provides rotation space for the stop plate 51, allowing the stop plate 51 to rotate out of the inner cavity of the insertion tube 4 and form a cross distribution with the insertion tube 4, thereby enhancing the tightness of the connection between the insertion tube 4 and the soil in the slope. An elastic baffle 6 is fixedly connected to the top of the inner cavity of the second rectangular groove 55. The bottom of the elastic baffle 6 is provided with a slope. The setting of the elastic baffle 6 plays a blocking role for the stop plate 51, so that the stop plate 51 is inserted vertically when the insertion tube 4 is inserted horizontally into the slope, thereby ensuring the smoothness of the insertion process.

[0013] Working principle: When using this utility model, the user first lays the grid mesh 1, making the two grid meshes 1 overlap. Then, the user uses a rolling device to press the surface of the grid mesh 1, so that the metal ribs 2 are flattened. Then, the user moves the pressure plate 3 to the overlapping position of the two grid meshes 1 and inserts the insertion tube 4 into the slope, so that the pressure plate 3 is tightly pressed into the overlapping position of the two grid meshes 1. Then, the user uses an electric drill to drive the threaded pin 52 to rotate. During the rotation, the threaded pin 52 is pushed downward horizontally. During the downward movement, the threaded pin 52 squeezes the anti-reverse plate 51. Under the guidance of the inclined surface 53, the anti-reverse plate 51 rotates and squeezes the soil until the threaded pin 52 is rotated into place. The anti-reverse plate 51 and the insertion tube 4 are at an intersecting angle, which enhances the pull-out strength of the insertion tube 4. Finally, the user puts the sealing plug 8 into the inner cavity of the circular groove 7 to cover the top of the threaded pin 52.

[0014] In summary, this three-dimensional reinforced geogrid uses geogrid 1 and metal reinforcing bars 2 to cover the slope. Then, with the cooperation of the insertion tube 4 and the anti-reverse component 5, the pressure plate 3 is stably installed at the overlapping position of the two geogrids 1, so that the geogrid 1 is tightly connected to the slope, thus achieving the purpose of effective elastic lifting and reliable and stable connection.
