Description

Technical Field

[0001] This invention relates to a geogrid device, preparation apparatus and method, and more particularly to a geogrid device, preparation apparatus and method based on the interlocking effect of composite pores. Background Technology

[0002] Geogrids, as a major geosynthetic material, are widely used in civil engineering projects such as highways, railways, slopes, and retaining walls due to their excellent performance in restricting lateral soil displacement, improving foundation bearing capacity, and enhancing structural stability. Therefore, geogrid devices are an important geosynthetic material. However, existing geogrid devices typically have square or rectangular mesh openings. Since the reinforcing bars are mainly distributed along the longitudinal and transverse directions, their mechanical strength is also concentrated in these two main directions. This results in traditional bidirectional geogrids having significantly weaker load-bearing capacity at angles such as 45°. Consequently, they cannot meet the needs of complex and multi-directional load directions and soil deformation trends in practical engineering applications. This invention, through its technical feature of a radiating rib receiving bearing capacity, effectively explores and studies the technical problem of meshes with square or rectangular openings at the technical level. The statements herein provide only background information related to this invention and do not necessarily constitute prior art. Based on the technical disclosure provided by the applicant on September 28, 2025, which addresses practical technical problems encountered during the work process, and the existing technical problems, technical features, and technical effects in similar patent documents and background information obtained through retrieval, the technical solution of this invention is proposed.

[0056] The thirty-fourth related technical solution involves the following steps: A polymer material containing a foaming agent and a polymer material without a foaming agent are extruded to obtain a multi-layer composite plate-type geogrid blank with an outer foamed layer and a core solid layer. The geogrid blank is then punched according to the arrangement of hole sections I, II, and III to obtain blanks for vertical rib sections, horizontal rib sections I, II, diagonal rib sections I, II, node sections I, and II. These blanks are then subjected to bidirectional temperature-controlled stretching to obtain the geogrid. When the geogrid device needs to be manufactured, the end of the central shaft containing the geogrid roll is placed in the U-shaped groove of the side-mounted roll holder, and the end of the central shaft containing the geotextile roll is placed in the U-shaped groove of beam section II. The central shaft is then wound up... One end is placed into the U-shaped groove of the winding frame, and the other rectangular end of the winding center shaft is inserted into the rectangular insertion hole of the control motor end of the winding frame. The geogrid is placed between roller section I and plate section I on the side winding frame. The geotextile is placed on node section II after exiting through perforated window sections I and II, thus obtaining the intermediate medium of the geogrid device. The end of the intermediate medium of the geogrid device is wound onto the winding center shaft, causing the swing telescopic cylinder to be in the extended state. The cylinder swings on the pin located between the frame and the swing plate seat, causing roller section I to act on the intermediate medium of the geogrid device. Nut section I and nut section II rotate on the screw section, causing nut section I and nut section II to separate from plate section III. Adjust the distance between roller section III and the intermediate medium of the geogrid device. After the distance adjustment is completed, rotate nut section I and nut section II in opposite directions on the screw section. This causes the inner end faces of nut section I and nut section II to act on plate section III respectively. Through the extension and retraction adjustment of the swing telescopic cylinder, the spring section is compressed. Place the lower end face of the heating strip onto the end face of the geogrid. Place the intermediate connecting bolt between the heating strip and the swing plate seat into the mounting hole of the heating strip and the through hole of the strip seat. Rotate the intermediate connecting nut between the heating strip and the swing plate seat on the intermediate connecting bolt. The heating strip is installed on the strip seat, and the control motor and heating strip of the winding frame are in working condition. The winding center shaft is rotated, causing the grid to move on plate I. The geotextile moves with the grid. Roller I on the side winding frame presses the grid, and the heating strip melts the end face of the grid. The geotextile is bonded to the melted body on the end face of the grid. Under the elastic energy storage of the spring, roller II presses the geotextile to obtain the geogrid device. Roller III and roller I on the winding frame press the geogrid device. The geogrid device is rolled up by the winding center shaft. When the geogrid device is completed, the control motor and heating strip of the winding frame are deactivated.

[0057] The technical effect of the above solution is that it enables the composite connection of mesh and fabric.

[0058] The technical advantages of this invention are as follows: I. Multi-directional load-bearing capacity and balanced performance: The geometric structure of the composite multi-directional performance-optimized grid effectively improves the weakness of traditional grids in non-primary directions, enabling the product to effectively resist deformation and transfer stress in all directions, thus improving the versatility and safety of engineering applications. II. Superior Interlocking, Stable and Efficient: The porous layer structure on the surface of the reinforcing ribs greatly increases the contact area and friction coefficient with the aggregate, allowing aggregate particles to embed. This creates a microscopic and macroscopic interlocking effect far superior to that of smooth surfaces, resulting in higher load transfer efficiency and a more stable and durable reinforcement effect. III. Integrated Structure and Multifunctional Function: Through a one-piece, multi-layered structure and thermal bonding process, the product's components (solid core layer, porous surface layer, geotextile) work synergistically, avoiding the risk of interlayer separation. The product integrates reinforcement, isolation, filtration, drainage, and stress absorption, simplifying construction procedures and improving the overall performance of the project. IV. Improved engineering life and reduced costs: When applied to road engineering, this composite grid can effectively limit the lateral deformation of the base layer or asphalt layer, absorb and disperse the stress generated by vehicle loads, significantly delay the generation and development of reflective cracks, thereby improving the fatigue life and load-bearing capacity of the pavement, and may allow for the reduction of structural layer thickness in the design, saving material and engineering costs.

[0059] In this technical solution, the radiating ribs that receive the load-bearing capacity are implemented by a grid.

[0060] In this technical solution, the geogrid and geotextile with the receiving capacity of the launch ribs are important technical features. In the technical field of geogrid devices, preparation devices and methods based on the interlocking effect of composite pores, it has novelty, inventiveness and practicality. The terms in this technical solution can be explained and understood by the patent literature in this technical field. Attached Figure Description

[0111] The present invention will be further described below with reference to embodiments. These embodiments are intended to illustrate the present invention and not to further limit the present invention.

[0112] A method for preparing a geogrid device based on the interlocking effect of composite pores includes the following steps: A polymer material containing a foaming agent and a polymer material without a foaming agent are extruded to obtain a multi-layer composite plate-type geogrid blank 1 with an outer foamed layer and a solid core layer. Holes are punched into the geogrid blank 1 according to the arrangement of pore sections I15, II16, and III17 to obtain a blank containing vertical ribs I10, horizontal ribs I11, horizontal ribs II12, diagonal ribs I13, diagonal ribs II14, node I18, and node II19. The geogrid 1 is then obtained through bidirectional temperature-controlled stretching. When it is necessary to fabricate the geogrid device, place the end of the central shaft with the geogrid roll 1 into the U-shaped groove of the side-laying frame 94, place the end of the central shaft with the geotextile roll 2 into the U-shaped groove of the beam part II 52, place one end of the winding central shaft into the U-shaped groove of the winding frame 3, and insert the other rectangular end of the winding central shaft into the rectangular insertion hole of the control motor end of the winding frame 3. Place the geogrid 1 between the roller section I41 and the plate section I951 located on the side-laying roll frame 94. After the geotextile 2 comes out from the permeable window body I53 and the permeable window body II64, place it on the node section II19 to obtain the intermediate medium body of the geogrid device. Then, wind up the end of the intermediate medium body of the geogrid device on the winding center shaft for installation. The oscillating telescopic cylinder 7 is extended, causing the cylinder 62 to oscillate on the pin located between the frame 95 and the oscillating plate seat 6. This causes the roller seat I 98 to act on the intermediate medium of the geogrid device, and the nut I 914 and nut II 915 to rotate on the screw 913, separating them from the plate III 61. The distance between the roller III 911 and the intermediate medium of the geogrid device is adjusted. After the distance adjustment is complete, the nut I 914 and nut II 915 rotate in the opposite direction on the screw 913. Rotation causes the inner end faces of nut part I 914 and nut part II 915 to act on plate part III 61 respectively. Through the extension and retraction adjustment of the swing telescopic cylinder 7, spring part 96 is compressed, placing the lower end face of heating strip 8 onto the end face of grid 1. The intermediate connecting bolt between heating strip 8 and swing plate seat 6 is placed into the mounting hole of heating strip 8 and the through hole of strip seat part 63. The intermediate connecting nut between heating strip 8 and swing plate seat 6 rotates on the intermediate connecting bolt between heating strip 8 and swing plate seat 6. Through the intermediate connecting bolt and nut, heating strip 8 is installed on strip seat part 63. The control motor and heating strip 8 of the winding frame 3 are in working condition, the winding center shaft is in rotating condition, the grid 1 moves on the plate part I 951, the geotextile 2 moves with the grid 1, the roller part I 41 on the side winding frame 94 presses the grid 1, the heating strip 8 melts the end face of the grid 1, the geotextile 2 is bonded to the melted body on the end face of the grid 1, under the elastic energy storage of the spring part 96, the roller part II 99 presses the geotextile 2 to obtain the geogrid device, the roller part III 911 and the roller part I 41 on the winding frame 3 press the geogrid device, and the geogrid device is rolled up by the winding center shaft. When the geogrid device is completed, the control motor and heating strip 8 of the winding frame 3 are in non-working condition.

[0113] In verifying this invention, the inventors abandoned the existing technical features of square or rectangular meshes and first proposed the technical feature of a radiating rib receiving load-bearing capacity. This resulted in the first unexpected technical effect: enabling the geogrid device to withstand forces in multiple directions, including longitudinal, transverse, and 45°, 60°, and 120°, thus improving its performance. The second unexpected technical effect: using the geogrid 1 as a load-bearing component of the geogrid device improved the stability of its installation. The third unexpected technical effect: using the geotextile 2 for isolation, filtration, and drainage improved the stability of the civil engineering project. The fourth unexpected technical effect: connecting the geotextile 2 and the geogrid 1 via the frame 95, swing plate seat 6, heating strip 8, and press roller 9 improved the heat-fusion connection between the geotextile 2 and the geogrid 1. Finally, the fifth unexpected technical effect was achieved. The system achieves the following unexpected technical effects: First, it enables the unwinding and rewinding of the geogrid 1, geotextile 2, and geogrid assembly via the side unwinding frame 94, the rewinding frame 3, and the upper unwinding frame 5, improving the production efficiency of the geogrid assembly and resulting in a sixth unexpected technical effect. Second, it enables the leveling treatment of the geogrid 1 and geogrid assembly via the end roller 4, improving the production effect of the geogrid assembly and resulting in a seventh unexpected technical effect. Third, it enables the adjustment of the compression state of the spring part 96 via the swing telescopic cylinder 7 and the positioning roller 91, ensuring the connection strength between the roller part II 99 and the geotextile 2 and the geogrid 1, resulting in an eighth unexpected technical effect. Fourth, it enables the mesh to no longer be square or rectangular, increasing the mesh density, improving the mesh distribution, and enhancing its composite reception effect with civil engineering, resulting in a ninth unexpected technical effect. Fifth, it enables the optimized arrangement of the mesh of the geogrid assembly, expanding the application range of the geogrid assembly through its fabrication.
