Description

Technical Field

[0001] This utility model relates to the field of civil engineering material testing technology, and in particular to a performance testing platform for building geosynthetics. Background Technology

[0002] With the rapid development of my country's economic construction, geosynthetics such as geogrids, geotextiles, and geomembranes are increasingly widely used in engineering structures. Their application scenarios have expanded from traditional functions such as reinforcement and seepage prevention in transportation infrastructure and water conservancy projects to fields such as intelligent monitoring, ecological restoration, pollution control, and earthquake resistance and disaster reduction. Technologically, innovations are moving towards high strength and lightweight, resistance to extreme environments, self-healing, and biodegradability. This is also driving the development of multi-field coupling testing, non-contact detection, and green recycling technologies. The domestic standard system is gradually improving, and the industry's international competitiveness is increasing. In the future, it will further develop towards intelligent, low-carbon, and multi-functional integration, continuously providing support for national infrastructure and ecological strategies.

[0003] However, existing traditional testing benches can only perform single performance tests such as tensile strength on geotextiles and geomembranes under normal conditions, and cannot simulate complex engineering scenarios such as high temperature, low temperature, and high humidity. As a result, the test data cannot reflect the performance degradation law of materials in actual service environments. For example, geomembranes may experience a decrease in tensile strength due to material softening at high temperatures, or creep fracture due to long-term water and oxygen erosion in high humidity environments. However, traditional equipment cannot capture the performance changes under such environmental coupling effects, making single test data lack correlation with actual working conditions and difficult to support material selection, life prediction, and engineering optimization design. Therefore, a performance testing bench for building geosynthetics is proposed to solve the above problems. Utility Model Content

As a result, the test data cannot reflect the performance degradation law of materials in actual service environments. For example, geomembranes may experience a decrease in tensile strength due to material softening at high temperatures, or creep fracture due to long-term water and oxygen erosion in high humidity environments. However, traditional equipment cannot capture the performance changes under such environmental coupling effects, making the single test data lack correlation with actual working conditions, and making it difficult to support material selection, life prediction, and engineering optimization design.

[0005] To achieve the above objectives, this utility model proposes a test bench for the performance of building geosynthetics, which includes a test bench, a display controller on the left side of the top of the test bench, a test box welded to the top of the test bench, a transparent door rotatably connected to the front of the test box, a tensile testing assembly inside the test box, and a simulation mechanism inside the test box. The simulation mechanism includes a humidity sensor and a temperature sensor located on the left side of the test chamber, with the sensing ends of both sensors located inside the test chamber. A humidification component is located on the right side of the top of the test bench, with its left side connected to the right side of the test chamber.

[0008] Preferably, the humidification assembly includes an ultrasonic humidifier disposed on the top right side of the test bench. The ultrasonic humidifier is electrically connected to the display controller. The output end of the ultrasonic humidifier is connected to a manifold. A solenoid valve is connected to the left side of the manifold. The solenoid valve is connected to the right side of the test chamber.

[0009] Preferably, the heating assembly includes a mounting plate embedded in the rear side of the test chamber, an electric heating tube is provided on the front side of the mounting plate, a heat-conducting aluminum plate is provided on the front side of the electric heating tube, and the heat-conducting aluminum plate is located on the rear side of the test chamber.

[0022] This invention provides a performance testing platform for geosynthetics, aiming to solve the problem that existing traditional testing platforms can only perform single performance tests such as tensile strength on geotextiles and geomembranes under normal conditions, and cannot simulate complex engineering scenarios such as high temperature, low temperature, and high humidity. As a result, the test data cannot reflect the performance degradation law of materials in actual service environments. For example, geomembranes may experience a decrease in tensile strength due to material softening at high temperatures, or creep fracture due to long-term water and oxygen erosion in high humidity environments. However, traditional equipment cannot capture the performance changes under such environmental coupling effects, making single test data lack correlation with actual working conditions, and making it difficult to support material selection, life prediction, and engineering optimization design.

[0023] like Figure 1-7 As shown, the present invention provides a test bench for the performance of building geosynthetics, including a test bench 1, a display controller 2 on the left side of the top of the test bench 1, a test box 3 welded to the top of the test bench 1, a transparent door 4 rotatably connected to the front of the test box 3, a tensile test assembly 5 inside the test box 3, and a simulation mechanism 6 inside the test box 3. The simulation mechanism 6 includes a humidity sensor 601 and a temperature sensor 602 located on the left side of the test chamber 3. The sensing ends of the humidity sensor 601 and the temperature sensor 602 are both located inside the test chamber 3. A humidification component 603 is located on the right side of the top of the test platform 1. The left side of the humidification component 603 is connected to the right side of the test chamber 3. A semiconductor cooler 604 is located on the right side of the test chamber 3. The semiconductor cooler 604 is electrically connected to the display controller 2. The cooling end of the semiconductor cooler 604 is located on the right side inside the test chamber 3. A heating component 605 is located at the bottom of the rear side inside the test chamber 3.

[0024] In the technical solution of this utility model, by setting up a display controller 2, a test chamber 3, a transparent door 4, a tensile testing component 5, and a simulation mechanism 6, the target temperature and humidity parameters are set through the display controller 2. The heating component 605 and the semiconductor cooler 604 respectively heat up or cool down the environment inside the test chamber 3, and the humidification component 603 releases water vapor into the chamber. The humidity sensor 601 and the temperature sensor 602 monitor the temperature and humidity inside the chamber in real time and feed back to the display controller 2, forming a closed-loop control system that accurately simulates high temperature, low temperature, and high humidity environments. At the same time, the tensile testing component 5 can clamp and position geosynthetic material samples such as geotextiles or geomembranes and apply axial tension. The display controller 2 synchronously collects temperature and humidity data and parameters such as force and displacement during the tensile process, realizing real-time monitoring of the tensile properties of materials under different environmental conditions. This allows the test data to truly reflect the performance of materials in actual complex engineering scenarios, providing a scientific basis for material performance evaluation and engineering applications.

[0025] Please refer to the following: Figure 3 The tensile testing assembly 5 includes a perforated plate 501 fixedly connected to the bottom side of the test chamber 3. A support rod 502 is welded to the top of the perforated plate 501. A hydraulic cylinder 503 is bolted to the top of the test chamber 3. The telescopic end of the hydraulic cylinder 503 passes through the top of the test chamber 3. A force sensor 504 is bolted to the telescopic end of the hydraulic cylinder 503. A connecting rod 505 is bolted to the bottom of the force sensor 504. A partition plate 506 is fixedly connected to the outside of the connecting rod 505. The partition plate 506 is slidably connected inside the test chamber 3. A clamping structure 507 is provided at the top of the support rod 502 and the bottom of the connecting rod 505. In this embodiment, by setting up a tensile testing component 5, its hydraulic cylinder 503 drives the power sensor 504 and connecting rod 505 to move vertically through the telescopic end. The clamping structure 507 of the support rod 502 and the connecting rod 505 fixes the two ends of the sample respectively. The hollow plate 501 provides stable support for the support rod 502. When the hydraulic cylinder 503 applies tension, the force sensor 504 monitors the tension value in real time and transmits it to the display controller 2. The partition plate 506 ensures that the connecting rod 505 slides vertically while separating the inside of its test box 3, thereby realizing accurate testing of the tensile strength of geosynthetic materials. With the help of the simulation mechanism 6, mechanical performance data under different environments can be acquired simultaneously.

[0026] For further information, please continue to refer to [link / reference]. Figure 4The clamping structure 507 includes a support 5071 welded to the top of the support rod 502 and the bottom of the connecting rod 505. A groove 5072 is provided on the inner side of the support 5071. A lead screw 5073 is rotatably connected inside the groove 5072. The right side of the lead screw 5073 passes through the front side of the groove 5072. A turntable 5074 is welded to the front side of the lead screw 5073. A slider 5075 is threadedly connected to the surface of the lead screw 5073. The slider 5075 is slidably connected inside the groove 5072. A clamping plate 5076 is fixedly connected to the inner side of the slider 5075. A fixing plate 5077 is fixedly connected to the front side of the inner side of the support 5071. The fixing plate 5077 is located in front of the clamping plate 5076. In this embodiment, by setting up a clamping structure 507, rotating the turntable 5074 drives the lead screw 5073 to rotate, which in turn drives the slider 5075 to move along the slide groove 5072, so that the clamping plate 5076 clamps the sample in the direction of the fixed plate 5077. Through the precision of the threaded transmission of the lead screw 5073, it can be adapted to samples of different thicknesses such as geotextiles and geomembranes, ensuring uniform force and reliable data during the tensile test.

[0027] Please continue to refer to this. Figure 5 The humidification component 603 includes an ultrasonic humidifier 6031 located on the top right side of the test bench 1. The ultrasonic humidifier 6031 is electrically connected to the display controller 2. The output end of the ultrasonic humidifier 6031 is connected to a manifold 6032, and a solenoid valve 6033 is connected to the left side of the manifold 6032. The solenoid valve 6033 is connected to the right side of the test chamber 3. In this embodiment, by setting the humidification component 603, the display controller 2 controls the ultrasonic humidifier 6031 to generate water mist, which is delivered to the test chamber 3 through the manifold 6032 and the solenoid valve 6033. The solenoid valve 6033 automatically adjusts its on / off state according to the set humidity threshold, realizing accurate simulation of the 30%-90%RH humidity environment in the test chamber 3. The humidity sensor 601 provides real-time feedback data to form a closed-loop control, providing stable conditions for studying the impact of high humidity environment on material performance.

[0028] Please refer to Figure 6 The heating component 605 includes a mounting plate 6051 embedded in the rear side of the test chamber 3. An electric heating tube 6052 is disposed on the front side of the mounting plate 6051, and a heat-conducting aluminum plate 6053 is disposed on the front side of the electric heating tube 6052. The heat-conducting aluminum plate 6053 is located on the rear side of the test chamber 3. In this embodiment, by setting the heating component 605, the electric heating tube 6052 generates heat after being energized, which is evenly conducted to the internal space of the test chamber 3 through the heat-conducting aluminum plate 6053. In conjunction with the semiconductor cooler 604, a wide temperature range of -20℃ to 80℃ can be achieved. The temperature sensor 602 monitors the temperature inside the test chamber 3 in real time and feeds it back to the display controller 2 to ensure the stability of the test environment temperature, which can simulate the softening or aging characteristics of materials under high temperature conditions.

[0029] Additionally, please refer to Figure 7 A collection trough 7 is provided in the middle of the top of the test bench 1, and a water collection hopper 8 is fixedly connected to the top of the collection trough 7. The water collection hopper 8 is located at the bottom of the perforated plate 501. In this embodiment, by setting up the collection trough 7 and the water collection hopper 8, if condensation or water droplets are generated in the test chamber 3, they can fall into the water collection hopper 8 through the perforated plate 501 and be collected by the collection trough 7. This structure avoids water accumulation from affecting the operation of the equipment and ensures the dryness of the test environment and the safety of the equipment.

[0030] Additionally, please refer to Figure 7 A drain valve 9 is installed on the front side of the test bench 1, and the rear side of the drain valve 9 is connected to the collection tank 7. In this embodiment, by setting the drain valve 9, the water accumulated in the collection tank 7 can be quickly discharged through the drain valve 9, which facilitates regular cleaning and maintenance, avoids long-term retention of water leading to bacterial growth or odor, and improves the convenience and hygiene of equipment operation.

[0031] Additionally, please refer to Figure 4 A rubber pad 10 is bonded to the inner side of the clamping plate 5076 and the fixing plate 5077, and the inner side of the rubber pad 10 has anti-slip texture. In this embodiment, by setting the rubber pad 10, the rubber pad 10 on the inner side of the clamping plate 5076 and the fixing plate 5077 increases the friction with the sample through the anti-slip texture, preventing the sample from slipping or shifting during the tensile process. At the same time, the elastic buffering effect of the rubber pad 10 can avoid excessive clamping force causing local damage to the sample, ensuring that the test results truly reflect the tensile properties of the material itself.
