Abstract
Description
Technical Field
[0001] This invention relates to the field of intelligent composite geomaterials technology, and particularly to a high-strength intelligent composite geomaterial structure. Background Technology
[0002] Composite geosynthetics are widely used in various civil engineering projects, playing a crucial role in areas such as road foundation reinforcement, seepage prevention for hydraulic dams, and slope protection. Traditional composite geosynthetics often employ planar layered structures, such as simple stacking of geomembranes, geotextiles, and geogrids. However, as engineering projects move towards more complex terrains and higher requirements, the drawbacks of this traditional structure have become increasingly apparent.
[0003] In some mountainous road slope protection projects, due to the large topographic relief and complex geological conditions, traditional planar layered composite geomaterials are unable to effectively disperse local stress. When subjected to external forces such as landslides and rainwater erosion, local stress concentration can lead to material delamination or tearing, greatly reducing the protective effect and potentially causing engineering accidents.
[0004] In some soft soil foundation treatment projects in coastal areas, traditional geotechnical materials rely solely on passive load-bearing and cannot detect key parameters such as stress and humidity in real time. Soft soil foundations are easily affected by factors such as changes in groundwater levels and seawater erosion. If abnormal changes in stress and humidity cannot be detected in time, it may lead to uneven foundation settlement, affecting the stability of the superstructure and posing potential safety hazards to the project.
[0005] To address these issues, we propose a high-strength intelligent composite geomaterial structure. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength intelligent composite geotechnical material structure.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A high-strength intelligent composite geomaterial structure includes a surface erosion-resistant layer, a gradient density flexible support layer, and a functional composite base layer. The surface erosion-resistant layer is disposed above the gradient density flexible support layer, and the gradient density flexible support layer is disposed above the functional composite base layer. The surface erosion-resistant layer, the gradient density flexible support layer, and the functional composite base layer are connected by a reinforcing structure. A humidity sensor array is provided in the functional composite base layer, and a stress sensor array is provided in the gradient density flexible support layer.
[0009] Preferably, the surface erosion-resistant layer is composed of a polyester fiber woven mesh.
[0010] Preferably, the surface of the erosion-resistant layer is coated with a silane coating around its perimeter.
[0011] Preferably, the gradient density flexible support layer adopts a three-dimensional honeycomb elastomer, and the honeycomb elastomer is provided with multiple honeycomb holes at equal intervals. The diameter of the honeycomb holes is 5-20mm, and the stress sensor array is disposed in the honeycomb holes.
[0012] Preferably, the functional composite substrate layer is provided with multiple drainage pipe networks, and the drainage pipe networks are connected through flow guide holes. The functional composite substrate layer is provided with a reinforcing rib structure, which is made of glass fiber bundles woven at a 45° angle. The humidity sensor array is set in the drainage pipe network.
[0013] Preferably, the reinforcing structure includes multiple anchor bolts that penetrate the surface erosion-resistant layer, the gradient density flexible support layer, and the functional composite substrate layer, and the anchor bolts are distributed at equal intervals.
[0014] In this invention, a surface erosion-resistant layer is first laid on top of a gradient density flexible support layer, and then the gradient density flexible support layer is placed on top of a functional composite base layer. Anchors, evenly spaced and penetrating all three layers, are used to firmly connect the surface erosion-resistant layer, the gradient density flexible support layer, and the functional composite base layer, forming an integrated composite geomaterial structure. A stress sensor array is installed within the honeycomb pores of the gradient density flexible support layer to monitor stress changes in real time. A humidity sensor array is installed within the drainage network of the functional composite base layer to obtain humidity information in real time. When rainfall or groundwater seepage occurs, water enters the functional composite base layer, and the drainage network, interconnected through guide holes, guides and discharges the water, preventing water accumulation and damage to the material structure.
[0015] This utility model has the following advantages:
[0016] 1. The gradient density flexible support layer adopts a three-dimensional honeycomb elastomer. Its honeycomb structure can undergo elastic deformation when subjected to force, dispersing local stress to a larger area. Compared with the traditional planar layered structure, it effectively avoids stress concentration, improves the stability and damage resistance of the material in complex terrain, reduces the risk of material delamination or tearing, and achieves stress dispersion.
[0017] 2. The installation of stress sensor array and humidity sensor array enables the composite geomaterial to have intelligent monitoring function, which can sense changes in key parameters such as stress and humidity in real time. Once an abnormality occurs, the project management personnel can promptly detect it and take corresponding measures to effectively prevent potential project hazards and ensure the safe and stable operation of the project.
[0018] 3. The drainage network and diversion holes in the functional composite base layer form an effective drainage system, which can remove moisture in time, reduce the humidity inside the material, reduce material aging and damage caused by moisture accumulation, and extend the service life of the material. At the same time, for some humidity-sensitive engineering scenarios, such as soft foundation treatment, good drainage performance helps to improve the stability of the foundation.
[0019] 4. The surface anti-erosion layer is composed of polyester fiber woven mesh and coated with silane coating. The polyester fiber woven mesh has a certain strength and flexibility, and can resist the erosion of water flow, wind and sand. The silane coating further enhances the surface's anti-corrosion and anti-erosion ability, protecting the underlying structure from external environmental damage.
[0020] In summary, this invention effectively avoids stress concentration, improves the stability and resistance to damage of materials in complex terrain, reduces the risk of material delamination or tearing, and can detect changes in key parameters such as stress and humidity in real time, effectively preventing engineering hazards and ensuring the safe and stable operation of the project. At the same time, the drainage network and diversion holes form an effective drainage system that can remove moisture in a timely manner, reduce the internal humidity of the material, and further enhance the surface's resistance to corrosion and erosion, protecting the underlying structure from external environmental damage.

[0029] 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.
[0030] Reference Figure 1-7 A high-strength intelligent composite geotextile structure includes a surface erosion-resistant layer 1, a gradient density flexible support layer 2, and a functional composite base layer 3. The surface erosion-resistant layer 1 is positioned above the gradient density flexible support layer 2, and the gradient density flexible support layer 2 is positioned above the functional composite base layer 3. The three layers are stacked one on top of the other. The surface erosion-resistant layer 1, positioned above the gradient density flexible support layer 2, serves to resist external erosion. The gradient density flexible support layer 2, in turn, is positioned above the functional composite base layer 3, providing flexible support and buffering for the entire structure. The functional composite base layer 3 acts as the foundation, supporting the upper structure and possessing multiple functions. The three layers are tightly connected through reinforced structures, forming a stable and collaborative integrated composite geotextile structure. The functional composite base layer 3 contains a humidity sensor array 7, and the gradient density flexible support layer 2 contains a stress sensor array 8. The sensors can acquire real-time humidity and stress information within the material structure, providing data support for its intelligent applications.
[0031] The surface anti-erosion layer 1 is composed of polyester fiber woven mesh. Polyester fiber has excellent properties such as high strength, wear resistance and corrosion resistance. The structure of the woven mesh gives the layer a certain degree of flexibility and breathability, which can effectively disperse external impact force and reduce excessive local stress, thereby improving the material's erosion resistance. At the same time, the porous structure of the polyester fiber woven mesh can also allow a small amount of water to permeate, avoiding pressure concentration caused by water accumulation, and further enhancing the stability of the material.
[0032] The silane coating has good waterproof, anti-fouling and weather resistance. It can form a protective film on the surface of polyester fiber woven mesh, preventing moisture, chemicals and other substances from eroding the woven mesh and extending the service life of the surface anti-erosion layer 1. The silane coating also has a certain self-cleaning function, which can reduce the adhesion of dust, dirt and other substances on the material surface, keep the material surface clean, and ensure the long-term stability of its anti-erosion performance.
[0033] The gradient density flexible support layer 2 adopts a three-dimensional honeycomb elastomer. Multiple honeycomb holes 5 are evenly spaced on the honeycomb elastomer, with a hole diameter of 5-20mm. The stress sensor array 8 is set in the honeycomb holes 5. The design of different hole diameters forms a gradient density, which can provide corresponding support force according to different stress conditions. When subjected to small pressure, the smaller honeycomb holes can provide a certain elastic buffer; while when the pressure increases, the larger honeycomb holes can also participate in deformation and jointly bear the pressure, improving the overall load-bearing capacity of the material. In addition, the honeycomb structure also has good sound absorption and vibration reduction effects, which can effectively reduce the impact of external vibration and noise on the material structure, and is suitable for some engineering scenarios with high requirements for environmental quietness.
[0034] Stress sensors can monitor stress changes in the layer in real time and transmit the data to the monitoring system. Analysis of this stress data allows for timely understanding of the material structure's stress state and identification of potential safety hazards. Once the stress exceeds a set threshold, the system can issue an early warning signal, alerting relevant personnel to take measures to ensure the safe and stable operation of the project.
[0035] The functional composite base layer 3 is equipped with multiple drainage pipe networks 4, which are connected through flow guide holes 6. The functional composite base layer 3 is equipped with a reinforcing rib structure, which is made of glass fiber bundles woven at a 45° angle. The humidity sensor array 7 is set in the drainage pipe network 4. When encountering rainfall or groundwater seepage, water enters the functional composite base layer 3. The drainage pipe network 4 can quickly collect the water and guide and discharge it through the flow guide holes 6. This can effectively prevent water accumulation from damaging the material structure and prevent problems such as material softening and corrosion caused by excessive water. It ensures the long-term stability of the material structure. The 45° angled weaving method can provide reinforcement in multiple directions, improve the overall strength and stiffness of the functional composite base layer 3, and the reinforcing rib structure can effectively resist the deformation and cracking of the material during the stress process, ensuring the integrity of the material structure.
[0036] Humidity sensors can acquire humidity information of the layer in real time. By monitoring and analyzing the humidity data, the moisture content inside the material can be understood. When the humidity rises abnormally, it indicates that there may be poor drainage or a large amount of external water entering. At this time, measures can be taken in time to deal with the situation, such as checking whether the drainage network is blocked and strengthening waterproofing measures to ensure the safety of the material structure.
[0037] The reinforced structure includes multiple anchors 9 that are installed throughout the surface erosion-resistant layer 1, the gradient density flexible support layer 2, and the functional composite base layer 3. The anchors 9 are evenly spaced and tightly connected to form a stable and collaborative integral composite geomaterial structure.
[0038] In this invention, the surface erosion-resistant layer 1 is first laid on top of the gradient density flexible support layer 2, and then the gradient density flexible support layer 2 is placed on top of the functional composite base layer 3. Anchor bolts 9, evenly spaced and penetrating the three layers, are used to firmly connect the surface erosion-resistant layer 1, the gradient density flexible support layer 2, and the functional composite base layer 3 together, forming an integral composite geomaterial structure. A stress sensor array 8 is installed within the honeycomb holes 5 of the gradient density flexible support layer 2 to monitor the stress changes borne by the layer in real time. A humidity sensor array 7 is installed within the drainage network 4 of the functional composite base layer 3 to obtain humidity information of the layer in real time. When rainfall or groundwater seepage occurs, water enters the functional composite base layer 3, and the drainage network 4 is interconnected through guide holes 6 to guide and discharge the water, preventing water accumulation from damaging the material structure.
[0039] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
