Description

TECHNICAL FIELD

[0001] The utility model relates to road anti-seismic technical field especially, relate to a kind of road anti-seismic test sand table of convenient reuse. BACKGROUND

[0002] Road anti-seismic test sand table is a comprehensive test platform integrated with advanced technology and practical design concept, it is designed especially for simulating and evaluating the performance of road structure under extreme conditions such as earthquake. The sand table is accurate to copy the scale size and construction details of actual road, combined with advanced anti-seismic simulation technology, provides an intuitive and efficient test environment for researchers, engineers and educators. In overall design, road anti-seismic test sand table ingeniously integrates road model, earthquake simulation device, data acquisition and analysis system and other key components. Road model is made of high-strength material that can simulate the material properties of real road according to its construction characteristics, to ensure the accuracy and reliability of test results. Earthquake simulation device can accurately simulate earthquakes of different magnitude, focal depth and seismic wave shape, providing a comprehensive anti-seismic test environment for road model. During the test, the sand table applies dynamic seismic force to the road model through the earthquake simulation device, while the integrated data acquisition and analysis system captures and records key data such as stress distribution, deformation and crack development of the road model under the action of earthquake in real time. These data not only provide valuable test basis for researchers, but also help engineers optimize road design, improve road anti-seismic performance and reduce damage to transportation infrastructure caused by earthquakes. In addition, road anti-seismic test sand table also has high customizability and scalability. Users can adjust the size, material, structure and other parameters of the road model according to specific test requirements to meet the anti-seismic test requirements in different scenarios. At the same time, the sand table can be combined with other test equipment, simulation software and other test equipment to form a more perfect anti-seismic test system, providing more comprehensive and in-depth solutions for road anti-seismic research.

[0003] The reusability of the road seismic test sand table is an important consideration in its design, which is directly related to the test cost, efficiency and environmental protection and many other aspects. Modular design: In order to facilitate reuse, the road seismic test sand table usually adopts modular design. This means that the sand table can be divided into multiple independent parts or components, each of which can be used, replaced or repaired individually. This design not only reduces maintenance costs, but also improves the flexibility and customizability of the sand table. Durable materials: The main structural components and road simulation materials of the sand table are usually made of high-strength, wear-resistant and corrosion-resistant durable materials. These materials can withstand the wear and impact of multiple tests, maintaining the stability and accuracy of the sand table. Easy to clean and maintain: In order to ensure the reusability of the sand table, its design also takes into account the ease of cleaning and maintenance. For example, the surface of the sand table may be made of easy-to-clean materials, and the structural components may be designed to be easily disassembled and assembled for regular maintenance and maintenance.
