Description

Technical Field

[0001] This application relates to the field of airport runway construction technology, and in particular to a self-testing device for the reaction modulus of runway foundation for airport runway construction. Background Technology

[0002] Currently, in the construction and maintenance of airport runways, the quality of the runway subgrade directly affects the overall performance and safety reliability of the runway. Among them, the subgrade response modulus is one of the key parameters for measuring the load-bearing capacity and stability of the subgrade. However, in the traditional testing process, manual sampling and testing are usually relied upon. This method is not only time-consuming and labor-intensive, but also difficult to ensure the authenticity and accuracy of the measurement results due to the randomness and limitations of sampling. In recent years, with the development of sensor technology and automated equipment, some new equipment and technical means for rapid on-site testing of subgrade characteristics have emerged. These means have improved work efficiency to a certain extent, but they also have problems such as high cost and complex operation, which limit their application scope.

[0003] Currently, there are two main approaches: one is the indirect measurement method based on laboratory conditions, which involves collecting representative samples and sending them to a professional laboratory for testing and analysis. Although this method can obtain relatively accurate data, it cannot meet the needs of rapid on-site decision-making due to its long cycle and slow feedback. The other approach is the application of some portable testing instruments that have emerged in recent years. These instruments can obtain preliminary indicators in a short time, making it easier for on-site personnel to adjust construction strategies in a timely manner. However, due to their high design complexity, they often require professional operation and have limited popularity.

[0004] First, traditional manual inspection methods are inefficient and highly susceptible to subjective factors. Second, even for some advanced automated inspection equipment, their high price is a major obstacle to widespread application. In addition, the operation process of existing equipment is relatively cumbersome and lacks sufficient convenience and ease of use, which is not conducive to large-scale promotion.

[0005] Therefore, this application proposes a self-testing device for the reaction modulus of runway foundation for airport runway construction. Utility Model Content

The entire device is constructed using a modular design, with standard plug-in interfaces connecting the various functional components, simplifying assembly and enhancing system flexibility and compatibility. To adapt to a wider range of working environments, a temperature compensation function module is added, utilizing a thermistor to monitor external temperature fluctuations in real time and correct sensor reading deviations, improving overall measurement accuracy.
