Description

Technical Field

[0001] This utility model relates to the field of geogrids, specifically to a geogrid that can be fixed to share the load. Background Technology

[0002] Geogrids are geosynthetic materials widely used in civil engineering, primarily for soil reinforcement, preventing landslides, and improving foundation bearing capacity. Traditional geogrids are typically fixed by covering them with soil after installation or using simple fixing devices. However, in practical applications, especially on slopes or in complex terrain, geogrids are prone to displacement or loosening, resulting in unsatisfactory reinforcement effects. Furthermore, the fixing effect of traditional devices is limited, making it difficult to ensure a firm connection between the geogrid and the soil, further affecting the stability and practicality of the geogrid. Therefore, there is an urgent need to develop a geogrid that can be effectively fixed to improve its strength, stability, and practicality. Existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a geogrid that can be fixed to share the load.

[0004] This utility model is achieved through the following technical solution:

[0005] A geogrid capable of fixing shared forces includes a geogrid body with several adjacent and evenly distributed diamond-shaped fixing holes. Matching diamond-shaped anchor frames are provided on the evenly distributed diamond-shaped fixing holes, and the holes are fixed by inserting anchors provided on the diamond-shaped anchor frames.

[0006] Alternatively, the diamond-shaped anchor bracket includes two anchors and a connecting ring arranged in a diamond shape, with the two anchors and the connecting ring connected and fixed together by a connecting strip.

[0007] Further optionally, the anchor includes a top cap, the lower part of which is connected to an anchor rod, and the upper part of the anchor rod is fitted with multiple barbs.

[0008] Further optional, the connecting strip is connected to the top cap of the anchor.

[0009] Alternatively, the anchor bolt may be configured with a miter cone shape, with barbs arranged on the outside of the miter cone in multiple rows, both vertically and horizontally.

[0010] Alternatively, the geogrid body may be composed of multiple transverse and longitudinal tie bars connected in an alternating pattern.

[0011] Alternatively, multiple transverse and longitudinal strips can form a grid.

[0012] The fixing holes are arranged in a diamond pattern and are set on the nodes of the grid mesh.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: This utility model provides a geogrid that can be fixed and shares the load, along with its diamond-shaped anchor frame and anchors. By inserting and fixing the diamond-shaped anchor frame and anchors, the problem of easy displacement or loosening of traditional geogrids on slopes or complex terrain is effectively solved, thereby improving the strength, stability and practicality of the geogrid. The fixed geogrid is subjected to the load as a whole with the working surface, effectively preventing road surface cracking and uneven settlement of the subgrade. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0021] like Figure 1 As shown, a geogrid capable of fixing shared forces includes a geogrid body 1. The geogrid body 1 has several adjacent and evenly distributed diamond-shaped fixing holes 5. Matching diamond-shaped anchor brackets 6 are provided on the evenly distributed diamond-shaped fixing holes 5. The anchors 8 provided on the diamond-shaped anchor brackets 6 are inserted and fixed. The diameter of the fixing hole 5 can fully enter the anchor rod 82 of the anchor 8 and is slightly larger by 1-3mm. The outer side of the fixing hole 5 is a recessed part that is slightly larger than the diameter of the top cap 81 to prevent the anchor 3 from being pulled out or loosened by external force, and it is easy for workers to see during construction.

[0022] The fixing holes 5 on the geogrid body 1 are evenly distributed in a diamond shape. This arrangement helps to distribute the stress evenly and improve the stability of the geogrid. The shape and size of the fixing holes 5 can be adjusted according to actual needs to ensure compatibility with the diamond-shaped anchor brackets 6. The design of the diamond-shaped anchor brackets 6 allows them to fit tightly with the fixing holes 5, further enhancing the fixing effect.

[0023] like Figure 2 As shown, the rhomboid anchor frame 6 includes two anchors 8 arranged in a rhomboid shape and a connecting ring 7. The two anchors 8 and the connecting ring 7 are connected and fixed by a connecting strip 9.

[0024] The diamond-shaped anchor bracket 6 can be inserted and fixed to the corresponding diamond-shaped fixing holes 5. Two anchors 8 are directly nailed into the two holes diagonally above the diamond-shaped fixing holes 5. The connecting ring 7 corresponds to the remaining two diamond-shaped fixing holes 5 and is integrally connected with the anchors 8 of the diamond-shaped anchor brackets 6 above, below, and to the left and right. In this way, the multiple connected diamond-shaped anchor brackets 6 have a high degree of integrity. When a landslide or collapse occurs in a certain part of the slope, the anchors 8 at the landslide location will distribute the force evenly to the other integrally connected anchors 8 through the connecting strip 9, resulting in a more uniform overall force distribution and effectively preventing slope slippage. At the same time, when the diamond-shaped anchor bracket 6 is installed and fixed, it corresponds to the corresponding diamond-shaped fixing holes 5, so that the anchors 8 are not missed when driving them into the fixing holes 5, ensuring the quality of construction.

[0025] like Figure 3 As shown, the anchor 8 includes a top cap 81, with an anchor rod 82 connected to the lower part of the top cap 81. Multiple barbs 83 are installed on the upper part of the anchor rod 82. The top cap 81 is used to provide a connection point between the anchor and the diamond-shaped anchor frame. The anchor rod 82 is used to insert into the soil to achieve a fixing effect. The barbs 83 are used to enhance the friction between the anchor rod 82 and the soil to prevent the anchor from loosening or falling off in the soil.

[0026] Anchor nail 8 is made of high-strength polymer material, with a length of 50-70mm and a nail head diameter of 5-7mm. It is a triangular pyramid with barbs 83. The barbs 83 are made of high-strength polymer material in one piece and have a certain degree of toughness. When subjected to inward force, they can fit tightly against the anchor nail, making it easy to insert into the soil.

[0027] like Figure 2 As shown, the connecting strip 9 is connected to the top cap 81 of the anchor 8. One end of the connecting strip is fixed to the top cap of the anchor, and the other end is connected to the connecting ring, thus forming a stable connection structure.

[0028] like Figure 3 As shown, anchor bolt 82 adopts a triangular cone design, with barbs 83 arranged in multiple rows on the outer side of the cone. The triangular cone design of the anchor bolt allows for better force distribution when inserted into the soil, enhancing the anchoring effect. The multiple rows of barbs further improve the pull-out resistance of the anchor bolt, ensuring the stability of the geogrid in complex terrain. The barbs 83 are small rectangular or fan-shaped, forming an angle of 20 to 30 degrees with the anchor bolt 82. Their size and angle can be adjusted in different environments to facilitate construction and ensure their effectiveness.

[0029] like Figure 4As shown, the geogrid body 1 is composed of multiple transverse tie bars 2 and longitudinal tie bars 3 connected in an alternating manner. The geogrid body 1 is made of high-strength polymer material. The multiple transverse tie bars 2 and longitudinal tie bars 3 form a grid mesh 4. The grid mesh 4 can be designed as a grid structure of 150mm*150mm to 250mm*250mm.

[0030] like Figure 4 As shown, the diamond-shaped fixing holes 5 are set on the nodes of the geogrid mesh 4. The diamond arrangement of the fixing holes corresponds to the node positions of the geogrid mesh, allowing the fixing holes to be accurately positioned at the intersections of the geogrid mesh. This arrangement not only improves the positional accuracy of the fixing holes but also enhances the overall stability and stress uniformity of the geogrid.

[0031] The implementation principle of a geogrid capable of fixing shared forces according to an embodiment of this application is as follows:

[0032] When reinforcing a slope, workers lay the geogrid roll of this utility model flat on the slope working surface. After laying it flat, multiple diamond-shaped anchor frames 6 are aligned with the diamond-shaped evenly distributed fixing holes 5 on the geogrid body 1. The two anchors 8 on the upper part of the diamond-shaped anchor frame 6 are driven into the corresponding two fixing holes 5. At the same time, the two connecting rings 7 of the diamond-shaped anchor frame 6 are aligned with the remaining two diamond-shaped evenly distributed fixing holes 5 on the lower part. Then, the other diamond-shaped anchor frames 6 are driven into the adjacent diamond-shaped evenly distributed fixing holes 5 on the top, bottom, left and right sides. The upper, bottom and left and right diamond-shaped anchor frames 6 are connected as a whole and the geogrid body 1 is fixed by the integrated anchors 8. This construction method is not only fast and efficient, but also the fixed geogrid and the working surface are stressed as a whole, which effectively prevents road surface cracking and uneven settlement of the subgrade.

[0033] When the slope area is large, multiple geogrid bodies 1 can be overlapped horizontally and downwards (e.g. Figure 5 As indicated, align the fixing holes 5, and then fix the multiple diamond-shaped anchor brackets 6 to achieve overall fixed connection of multiple geogrid bodies 1, ensuring uniform force distribution.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
