[0002] Geotechnical barriers are commonly used for waterproofing and military isolation, etc. Please refer to [link / reference]. Figure 15 As shown, the existing geogrid consists of multiple interconnected cubic mesh fences. Each mesh fence has sandbags on its inner side to hold soil and sand. In use, filling each sandbag with sand and gravel easily forms a protective wall. Please refer to [link / reference]. Figure 16 As shown, when the height of the retaining wall needs to be increased, multiple layers need to be stacked; and to ensure the stability of the retaining wall, multiple geogrids need to be placed side by side at the bottom. This makes the geogrid laying process cumbersome when the height of the retaining wall needs to be increased, requiring more geogrids, wasting materials and increasing expenses. To solve the above problems, this invention provides a geogrid structure for rapidly filling sandbags during flood control and disaster relief. Summary of the Invention

Detailed Implementation
[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0038] Example: Figures 1 to 16 As shown, this invention provides a geotechnical guardrail structure for rapid sandbag filling during flood relief, comprising: several interconnected square frames 1, with sandbags 2 for holding sand and gravel placed on the inner side of any square frame. Each square frame 1 includes two extendable rectangular mesh members 3 and two foldable rectangular mesh members 4; each extendable rectangular mesh member 3 includes a vertical plate 31 and two first rectangular protective nets 32, with one side of each first rectangular protective net 32 slidably installed inside the vertical plate 31. When the two first rectangular protective nets 32 slide relative to each other, the length of the extendable rectangular mesh member 3 is adjustable to adjust the width of the square frame 1, adapting to form geotechnical guardrails of different widths and strengths.
[0039] The foldable rectangular mesh 4 includes two second rectangular guard nets 41, the two second rectangular guard nets 41 are hinged at their sides to form the foldable rectangular mesh 4; within the same foldable rectangular mesh 4, the side of one second rectangular guard net 41 is hinged to the side of a first rectangular guard net 32 located on the outer side of a retractable rectangular mesh 3, and the side of another second rectangular guard net 41 is hinged to the side of a first rectangular guard net 32 located on the inner side of another retractable rectangular mesh 3, so that the two retractable rectangular meshes 3 are parallel to each other and centrally symmetrical, forming a frame; the connection method between the two second rectangular guard nets 41 and the retractable rectangular mesh 3 within the foldable rectangular mesh 4 ensures the formation of a stable rectangular frame.
[0040] Adjacent frames share the same retractable rectangular mesh 3; sandbags 2 are cubic in shape, and are partially fixed around the perimeter of the sandbags 2 on the two retractable rectangular mesh 3 and the two foldable rectangular mesh 4, ensuring that the sandbags 2 are stably installed inside the frames 1 to hold sand and gravel to form a geotechnical retaining wall. When the included angle between the two second rectangular protective nets 41 within the same foldable rectangular mesh 4 is 0°, the two retractable rectangular mesh 3 are close to each other, and the frames are in a retracted state; when the included angle between the two second rectangular protective nets 41 within the same foldable rectangular mesh 4 is 180°, the two retractable rectangular mesh 3 are far apart, and the frames are in an unfolded state.
[0041] In this embodiment, a frame 1 is formed by two retractable rectangular mesh pieces 3 and two foldable rectangular mesh pieces 4, and sandbags 2 are installed inside the frame. When the sandbags are quickly filled for flood control and the geotechnical guardrail structure needs to be stacked in multiple layers to form a higher protective wall, the two first rectangular guardrails 32 inside the bottom retractable rectangular mesh piece 3 are simply stretched outward to form a wider protective guardrail, thus achieving a stable multi-layer protective wall. This method is convenient, efficient, and saves materials.
[0042] For further details, please refer to Figures 7 to 10 as well as Figure 16 As shown, the retractable rectangular mesh 3 also includes a limiting component, which includes a U-shaped insert 33. A rectangular slot is opened at the side end of the upright plate 31. Horizontal limiting strips 311 are symmetrically provided on the upper and lower bottom surfaces of the rectangular slot. The two horizontal limiting strips 311 and the inner surface of the rectangular slot form a horizontal slide rail. Please refer to [link to relevant documentation]. Figure 12 and Figure 13 As shown, one end of the horizontal bar of the first rectangular protective net 32 is integrally provided with a limiting hook 321. The side end of the first rectangular protective net 32 with the limiting hook 321 is slidably installed in the horizontal slide rail to ensure that the two first rectangular protective nets 32 do not interfere with each other and slide stably when they slide relative to each other. Several pairs of insertion holes are evenly distributed on the upper surface of the upright plate 31. Each pair of insertion holes includes two insertion holes 312, and the two insertion holes 312 in the pair of insertion holes correspond to the two horizontal slide rails respectively. The two side strips of the U-shaped insert 33 are inserted into the two insertion holes 312 in the pair of insertion holes respectively. When the first rectangular protective net 32 is pulled outward, the limiting hook 321 hooks the side strip of the U-shaped insert 33. The U-shaped insert 33 adjusts the stretching length of the telescopic rectangular net 3 by being inserted into the pairs of insertion holes at different positions.
[0043] For further details, please refer to Figure 11 and Figure 12 as well as Figure 15As shown, both the first rectangular protective net 32 and the second rectangular protective net 41 are grid-like rectangular net structures formed by interconnecting several horizontally distributed horizontal bars and several vertically distributed vertical bars. The first rectangular protective net 32 and the second rectangular protective net 41, as well as the two second rectangular protective nets 41, are connected by non-elastic helical springs 5. The outermost vertical bars of the first rectangular protective net 32 and the outermost vertical bars of the second rectangular protective net 41 are located within the same non-elastic helical spring 5, allowing the first rectangular protective net 32 and the second rectangular protective net 41 to rotate relative to each other. The outermost vertical bars of the two second rectangular protective nets 41 are located within the same non-elastic helical spring 5, allowing the two second rectangular protective nets 41 to rotate relative to each other. This ensures that the two second rectangular protective nets 41 can be folded and stacked to accommodate the frame 1. When the two second rectangular protective nets 41 are unfolded and located on the same plane, the frame 1 unfolds to allow sand and gravel to be filled.
[0044] For further details, please refer to Figure 3 and Figure 5 As shown, several first binding ropes 21 are evenly distributed along the vertical direction on the outer side of the four sides of the sandbag 2. The first binding ropes 21 are tightly tied to the outermost vertical strip of the first rectangular protective net 32 or the outermost vertical strip of the second rectangular protective net 41. The four sides of the sandbag 2 are fixed to ensure that the sandbag 2 can be fully opened to facilitate filling with sand and gravel.
[0045] For further details, please refer to Figure 2 , Figure 3 , Figure 5 as well as Figure 6 As shown, two rows of second binding ropes 22 are evenly distributed along the vertical direction on the left and right outer sides of the sandbag 2. The second binding ropes 22 in the same row are tied to the outside of the horizontal bar of the second rectangular protective net 41, so that the left and right sides of the sandbag 2 are close to the second rectangular protective net 41. When two adjacent second rectangular protective nets 41 rotate relative to each other, the sandbag 2 can shrink accordingly. That is, the second binding ropes 22 are tied to the horizontal bar and can move within the grid. When two second rectangular protective nets 41 rotate relative to each other, the left and right sides of the sandbag 2 can expand and contract accordingly, which is convenient and practical.
[0046] For further details, please refer to Figure 5 As shown, the sandbag 2 is fixedly installed on the inner side of the upright plate 31 by two rows of bubble studs 23 on both the front and rear sides; the distance between the bubble studs 23 and the side ends of the upright plate 31 is 1 / 4 to 1 / 3 of the width of the upright plate 31, leaving sufficient space for the corrugated bag section 24 mentioned below, so as to accommodate the shrinkage of the front and rear sides of the sandbag 2. For further details, please refer to... Figure 3 As shown, the sandbag 2 has two corrugated bag sections 24 that are symmetrically arranged on both the front and rear sides. The corrugated bag sections 24 are located between a row of bubble studs 23 and the outermost vertical strip of the first rectangular protective net 32 to accommodate the movement of the first rectangular protective net 32. The corrugated bag sections 24 adapt to the relative movement of the first rectangular protective net 32 and adapt to the length of the retractable rectangular net 3.
[0047] For further details, please refer to Figure 14 As shown, when two geotechnical guardrail structures for rapid sandbag filling in flood control need to be stacked to increase the overall protection height, the two first rectangular protective nets 32 within the expandable rectangular mesh 3 of the lower geotechnical guardrail structure for rapid sandbag filling in flood control are stretched outward, increasing the width of the geotechnical guardrail structure for rapid sandbag filling in flood control. Then, the other geotechnical guardrail structure for rapid sandbag filling in flood control is stacked on top of it; unlike... Figure 18 Such geotechnical guardrails located at the bottom layer require multiple sections tied side by side, which not only saves materials but also makes them easy to deploy and store.
[0048] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
