[0002] The slope is a slope with a certain slope on both sides of the roadbed to ensure the stability of the roadbed. The slope is easily eroded and washed away by surface water. Long-term erosion will lead to soil erosion of the slope, which will lead to dangerous phenomena such as slope collapse and landslide. Therefore, reinforcement measures are needed to protect the overall stability of the slope and extend the service life of the slope. At present, most concrete retaining walls are used for protection, but the construction of concrete retaining walls is difficult, the construction period is long, and it lacks aesthetics. The later maintenance cost is high, so it is necessary to improve the slope protection measures.

The three-dimensional vegetation net is connected to the road engineering slope by a U-shaped anchor, and concrete top pressure and foot guard are used, and the three-dimensional vegetation net is fixed by U-shaped anchors, which has the advantages of good fixing effect, simple construction technology, short construction period, low cost, small engineering quantity, good protection effect, etc. The utility model proposes a geogrid for slope protection of other structures.

[0025] Example

[0026] like Figure 1-4 As shown, a geogrid for slope protection includes a geogrid body 1, two adjacent sides of the geogrid body 1 are provided with mounting plates 2, the remaining two sides of the geogrid body 1 are provided with mounting plates 3, a plurality of sleeves 4 are provided at the bottom of the mounting plate 2, a plurality of through holes are opened on the mounting plate 2, the through holes are connected with the cavity in the sleeve 4, and the diameter of the through holes is equal to the top diameter of the cavity in the sleeve 4, a plurality of plug-in rods 5 are provided at the bottom of the mounting plate 3, and the size and number of the sleeves 4 and the plug-in rods 5 match.

[0027] It is worth mentioning that the geogrid body 1 can enhance the stability of the slope soil and improve the quality of the project. The mounting plate 1 2 and the mounting plate 2 3 provide installation positions for the sleeve 4 and the plug-in rod 5. The splicing of the geogrid is achieved through the cooperation of the sleeve 4 and the plug-in rod 5. Specifically, the sleeve 4 of the geogrid located at the bottom is first inserted into the soil, and then the plug-in rod 5 of the geogrid located at the top is inserted into the soil through the through hole and the cavity of the sleeve 4 of the geogrid located at the bottom. At this time, the outer surface of the plug-in rod 5 fits with the inner surface of the sleeve 4, thereby achieving a fixed connection between adjacent geogrids.

[0028] In some feasible embodiments, the lower surface of the mounting plate 1 2 is flush with the lower surface of the geogrid body 1, and the thickness of the mounting plate 1 2 is half the thickness of the geogrid body 1; the lower surface of the mounting plate 2 3 is flush with the lower surface of the geogrid body 1, and the thickness of the mounting plate 2 3 is half the thickness of the geogrid body 1. When adjacent geogrids are spliced ​​up and down, the mounting plate 1 2 is located below the mounting plate 2 3, and the thickness of the mounting plate 1 2 and the mounting plate 2 3 after overlapping is equal to the thickness of the geogrid body 1, avoiding the situation where the thickness of the splicing part increases due to the overlap of the mounting plate 1 2 and the mounting plate 2 3 during splicing.

[0029] In some feasible embodiments, the plug-in rod 5 is a hollow structure, a screw 6 is slidably provided inside the plug-in rod 5, a nut 7 is sleeved on the top of the screw 6, the nut 7 is threadedly connected to the screw 6, an expansion tube 8 is provided at the bottom of the plug-in rod 5, the top of the expansion tube 8 is fixedly connected to the plug-in rod 5, and the bottom of the expansion tube 8 is fixedly connected to the bottom of the screw 6. The expansion tube 8 is an expansion tube 8 formed by a plurality of vertically arranged strip expansion pieces around the central axis. The strip expansion pieces form the expansion tube 8, so that when the distance between the top and the bottom of the expansion tube 8 becomes smaller, the strip expansion pieces open in an arc shape to achieve expansion.

[0030] Specifically, after the plug-in rod 5 is inserted into the sleeve 4, the nut 7 is rotated until it contacts the upper surface of the mounting plate 3. Since the nut 7 can no longer move forward at this time, continuing to rotate the nut 7 will cause the screw rod 6 to move upward. The upward movement of the screw rod 6 drives the bottom of the expansion tube 8 to move upward. Since the top of the expansion tube 8 is fixedly connected to the top of the plug-in rod 5, the top of the expansion tube 8 cannot move upward, so the middle part of the expansion tube 8 will expand outward. The nut 7 continues to be rotated until it cannot rotate. At this time, the screw rod 6 drives the bottom of the expansion tube 8 to contact the top of the expansion tube 8. The expansion of the expansion tube 8 prevents the plug-in rod 5 from detaching from the sleeve 4 or the soil, thereby enhancing the tensile strength of the geogrid.

[0031] In some feasible embodiments, a plurality of pipe clamps 9 are arranged vertically in a row on the top of the geogrid body 1. For some slopes with vegetation, watering is required, and the pipe clamps 9 can be used to fix the water pipes to prevent the water pipes from moving.

[0032] In addition, it should be understood that although this specification is described in accordance with the implementation methods, not every implementation method contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art. So far, each embodiment of the present disclosure has been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution disclosed here. The scope of the present disclosure is defined by the attached claims.
