Description

Technical Field

[0001] The invention relates to the technical field of geological disaster experimental research, and in particular to a retractable rainfall simulation device and a test method. Background Art

[0002] In nature, rainfall of different intensities usually leads to various natural disasters on the slopes, such as mudslides, landslides and other geological disasters. These natural disasters not only pose a certain threat to animals and plants, but also pose a threat to people living nearby or places with intensive human activities. In order to solve the related safety hazards, the purpose of this invention is to explore the critical conditions for the generation of geological disasters under different soil qualities and rainfall intensities.

[0003] In order to obtain this critical condition, it is necessary to use relevant experimental devices for experiments. At present, there are many devices and methods on the market for simulating geological disasters caused by rainfall, but most of them have certain limitations. For example, when building an experimental device on the slope and conducting an experiment to simulate geological disasters caused by rainfall, when the critical condition is reached, along with the occurrence of destruction, the experimental device erected on the slope will be destroyed, thus causing certain damage to the device. It is also impossible to explore the impact of continued rainfall on it after the disaster occurs, which also has great disadvantages. Summary of the invention

Different from the traditional method, the device will not cause damage to the structure of the device when the geological disaster is caused by rainfall. Therefore, it is possible to further explore a series of geological disaster experiments caused by rainfall. The device is easy to disassemble and transport.
