Description

Technical Field

[0001] This utility model relates to the field of geogrid technology, specifically a steel-plastic composite geogrid. Background Technology

[0002] Geogrids are two-dimensional mesh materials made of high molecular polymers such as polypropylene and polyethylene through thermoplastic stretching or welding. Geogrids are a major geosynthetic material, and compared with other geosynthetic materials, they have unique properties and functions. Geogrids are often used as reinforcement materials in reinforced soil structures or composite materials.

[0003] Chinese patent CN215290172U discloses a tensile-resistant and corrosion-resistant steel-plastic composite geogrid, comprising multiple transverse and longitudinal geogrid strips. Connecting plates are fixedly connected to both ends of the transverse geogrid strips and to the top and bottom of the longitudinal geogrid strips. Multiple steel wire structures are arranged at the center of each of the transverse and longitudinal geogrid strips. The outer walls of each set of steel wire structures are coated with a polymer material layer. An anti-corrosion layer is provided on the outer surface of each polymer material coating layer, and a flame-retardant layer is provided on the outer surface of each anti-corrosion layer. This invention features a simple and convenient structure. Through the design of simple connecting plates and other structural devices, the device can be applied to large-area installation, greatly enhancing its constraint effect on the soil and significantly improving its convenience and practicality.

[0004] However, the aforementioned patent uses multiple screws to pass through the transverse and longitudinal geogrids to fix the upper pressure plate and the whole structure, preventing the transverse and longitudinal geogrids from shaking. However, during the process of multiple screws passing through the transverse and longitudinal geogrids, the multiple screws are prone to damage to the internal structure, thereby affecting its overall tensile strength.

[0010] Preferably, there are several injection tubes, the upper surface of which is threaded, and the lower end of the injection tube passes through the upper cover, the upper geogrid, the lower geogrid and the lower cover in sequence.

[0011] Preferably, the upper end of the isolation ring is in close contact with the lower cover, the isolation ring does not contact the fixed cone, and the surface of the fixed cone has several through holes.

[0012] Preferably, the surfaces of several of the injection tubes are connected to a fixing nut by surface threads, and one side of the fixing nut is in close contact with the upper cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the connection between the upper cover and the lower cover can be used to fix the whole without damaging the internal structure of the upper geogrid and the lower geogrid; the conical teeth and the fixing cone can make the connection between the whole and the ground more secure; the isolation ring and the fixing nut can further fix the upper cover and the lower cover, thus avoiding the damage to the tensile strength of the main body caused by drilling.

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4 This utility model provides a technical solution: a steel-plastic composite geogrid, comprising: an upper geogrid 2 and an upper cover 4. Several upper geogrids 2 and lower geogrids 3 are provided, which can be connected and fixed to the ground during construction. Several slots 6 are formed on the surfaces of the upper geogrids 2 and lower geogrids 3, and these slots 6 are interlocked. At this time, the several upper geogrids 2 and lower geogrids 3 are connected to the lower geogrids 3. The connection is completed by mortise and tenoning the lower geogrids 3 together. The number of connections is determined by the construction scope. The surfaces of the upper geogrids 2 and the lower geogrids 3 are simultaneously in contact with the mesh cloth 1, which can fix the whole structure. Several upper geogrids 2 and several lower geogrids 3 are fixedly connected to the side without the slot 6 by several conical teeth 8. The conical teeth 8 can make the connection between the upper geogrids 2 and the lower geogrids 3 and the ground more stable. The conical teeth 8 are evenly arranged in a straight line to facilitate installation.

[0021] After measuring the construction area, several upper geogrids 2 and several lower geogrids 3 were tenoned together, then installed and the conical teeth 8 were inserted into the ground, and then further fixed with mesh cloth 1.

[0022] Several upper and lower covers 4 and 5 are provided, both in a cross shape, to facilitate the simultaneous fastening of the upper geogrid 2 and the lower geogrid 3. The upper and lower covers 4 and 5 are in contact with each other. The threaded ends of several screws 7 pass through the upper cover 4 and are threadedly connected to the lower cover 5. Each upper and lower cover 4 and 5 has an upper geogrid 2 and a lower geogrid 3 fastened to its inner wall, preventing the upper and lower geogrids 2 and 3 from shaking. Several injection tubes 9 are provided, with surface threads 10 on their upper surface to facilitate the entry of mud. The lower end of the injection tube 9 passes through the upper cover 4, the upper geogrid 2, and the lower geogrid 3 in sequence. The components include a geogrid 2, a lower geogrid 3, and a lower cover 5. An isolation ring 12 and a fixing cone 13 are welded to the surface of the injection tube 9. The upper end of the isolation ring 12 is in close contact with the lower cover 5. The lower cover 5 can be limited and fixed by the isolation ring 12. The isolation ring 12 does not contact the fixing cone 13. Several through holes 14 are opened on the surface of the fixing cone 13. When the mud enters from the injection tube 9, it can enter the fixing cone 13 and then flow out through the through holes 14. The surfaces of several injection tubes 9 are threaded with fixing nuts 11 through surface threads 10. One side of the fixing nut 11 is in close contact with the upper cover 4. The upper cover 4 can be fixed and limited by the fixing nut 11.

[0023] After the upper cover 4 and the lower cover 5 are installed on the surfaces of the upper geogrid 2 and the lower geogrid 3, the upper cover 4 and the lower cover 5 are connected and fixed by screws 7. Then, the injection tube 9 is inserted and fixed by fixing nut 11. At this time, the upper cover 4 and the lower cover 5 can be further fixed by fixing nut 11 and isolation ring 12.

[0024] In actual use, the mortise and tenon joint between the upper geogrid 2 and the lower geogrid 3 can limit the thermal contact. The connection between the upper cover 4 and the lower cover 5 can fix the whole without damaging the internal structure. The conical teeth 8 and the fixing cone 13 can make the connection between the whole and the ground more secure. The isolation ring 12 and the fixing nut 11 can further fix the upper cover 4 and the lower cover 5, thus avoiding damage to the tensile strength.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
