In the application of the above patent's technical solution, the structure ballasted on the geogrid is not easy to connect with the soft sheet, resulting in poor installation and use of the soft sheet. Therefore, in order to better realize the connection function of the ballast structure on the soft sheet, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the ballast connection structure of the soft sheet in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing structures ballasted on geogrids are not easy to connect with flexible panels, and to propose a geogrid composite flexible panel.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A geogrid composite flexible sheet includes a geogrid composite component. The top of the geogrid composite component has multiple ballast structures, each consisting of a concrete block, connecting components, and connecting strips. Each connecting component includes a vertical pole, with a lifting ring fixedly connected to the top of the pole and a cross-shaped connecting bar fixedly connected to the bottom. Multiple ends of the connecting bar are collectively fixedly connected to an inner connecting frame. Multiple connecting rods are fixedly connected to the top of the inner connecting frame. A concrete block is poured between the multiple connecting rods, the inner connecting frame, and the connecting bars. An outer connecting frame is fixedly connected to the inner side of the multiple connecting rods. A connecting ring is fixedly connected to the other end of each connecting rod. A connecting strip passes through the connecting ring and is sewn to the connecting ring. The other end of the connecting strip is sewn to the geogrid composite component.

[0007] Furthermore, the geogrid composite component includes a first geotextile layer, an impact-resistant fabric layer fixedly connected to the top of the first geotextile layer, a geogrid layer on the top of the impact-resistant fabric layer, a second geotextile layer on the top of the geogrid layer, and the second geotextile layer and the impact-resistant fabric layer are sewn together.

[0008] Furthermore, the impact-resistant fabric layer is a polyester filament woven fabric layer.

[0009] Furthermore, the geogrid layer is a fiberglass geogrid layer.

[0010] Furthermore, the connecting component is a connecting steel bar component.

[0011] Furthermore, the connecting rod has a U-shaped structure.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By placing the connecting strip on the outside of the concrete block and then sewing the connecting strip to the geogrid composite component, it is easier to connect the ballast structure and the soft slab, thereby improving the installation and use effect of the soft slab.

[0014] 2.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A geogrid composite flexible structure includes a geogrid composite component 1. The top of the geogrid composite component 1 is provided with multiple ballast structures 2. Each ballast structure 2 consists of concrete blocks 3, connecting components 4, and connecting strips 5. The connecting components 4 include uprights 401, with lifting rings 402 welded to the top of the uprights 401. One end of a steel wire rope is attached to the lifting ring 402 to facilitate the hoisting of the ballast structure 2. The bottom of the uprights 401 is welded with cross-shaped connecting ribs 407. Multiple ends of the connecting ribs 407 are welded together to an inner connecting frame 406. The top of the inner connecting frame 406 is welded with multiple connecting rods 403. 403 is a U-shaped structure. Concrete block 3 is poured between multiple connecting rods 403, inner connecting frame 406, and connecting bar 407. An outer connecting frame 405 is welded to the inner side of the multiple connecting rods 403. A connecting ring 404 is welded to the other end of the connecting rod 403. A connecting cloth tape 5 is threaded through the connecting ring 404 and is sewn to the connecting ring 404. The other end of the connecting cloth tape 5 is sewn to the geogrid composite component 1. The connecting cloth tape 5 is made of high-strength nylon tape with a thickness of 3mm and a breaking strength ≥50kN. It is double-stitched with the geogrid composite component 1 with a stitch spacing ≤50mm.

[0023] The geogrid composite component 1 includes a first geotextile layer 101, an impact-resistant fabric layer 102 sewn to the top of the first geotextile layer 101, a geogrid layer 103 on top of the impact-resistant fabric layer 102, and a second geotextile layer 104 on top of the geogrid layer 103. The second geotextile layer 104 is sewn to the impact-resistant fabric layer 102. The second geotextile layer 104 helps to further protect the geogrid layer 103 and maintain the integrity of the entire structure.

[0024] The first geotextile layer 101 and the second geotextile layer 104 are made of polypropylene material with a unit area mass ≥200g / m² and a thickness ≥1.5mm; the impact-resistant fabric layer 102 is woven from 600D polyester filament with a breaking strength ≥30kN / m.

[0025] The impact-resistant fabric layer 102 is a polyester filament woven fabric layer, which not only enhances the overall structure's impact resistance, but also effectively disperses and absorbs external forces, protecting the underlying structure from damage.

[0026] The geogrid layer 103 is a fiberglass geogrid layer, which increases the load-bearing capacity and stability of the structure and plays an important supporting role.

[0027] Connecting component 4 is a connecting steel reinforcement assembly. The steel reinforcement bears tensile stress in the concrete block 3, compensating for the low tensile strength of the concrete. When the concrete block 3 is bent due to water flow impact or stone collision, the steel reinforcement inhibits crack propagation through tensile force, maintains the integrity of the concrete block 3, and provides compressive strength efficiency.

[0028] The working principle of this embodiment is as follows: When in use and during construction, the geogrid composite component 1 is first laid on the riverbed, and then the ballast structure 2 is arranged at a spacing of 2m×2m. It is then connected to the composite component by sewing the connecting cloth strip 5, and finally the overall sinking operation is carried out.

[0029] The first geotextile layer 101 and the second geotextile layer 104 serve as filter layers, allowing water to flow through while effectively blocking soil particle loss, preventing water erosion from causing the foundation soil to hollow out, maintaining structural stability, and also dispersing concentrated stress. Then, the impact-resistant fabric layer 102 uses a polyester filament woven fabric layer to provide excellent tear resistance and puncture resistance, which can resist dynamic load impacts such as water erosion. Next, the geogrid layer 103 uses a fiberglass geogrid layer with high deformation resistance and will not creep.

[0030] Then, the connecting strip 5 is placed on the outside of the concrete block 3, and the connecting strip 5 is sewn to the geogrid composite component 1, which facilitates the connection between the ballast structure 2 and the geogrid composite component 1, making it convenient and quick.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
