The utility model belongs to the technical field of material storage, and provides a large-capacity particle storage bin which comprises a bin body, a conical discharging section arranged at the lower end of the bin body, a bin cover arranged at the feeding end of the bin body, and a separation assembly arranged in the bin body and used for separating the storage space of the bin body. The separation assembly comprises two channels symmetrically formed in the two sides of the interior of the bin body. According to the utility model, the first-in and first-out of the particle materials can be ensured through the separation assembly, and the first-in and first-out of the particle materials which are easy to deteriorate, overdue or affected with damp to influence the quality can ensure that the materials which are stored firstly are preferentially used. The influence on the material quality due to overlong storage time can be effectively avoided, the stable and reliable quality of the produced product is ensured, the preferential use of the firstly stored material is ensured, and the retention time of the material in a warehouse is reduced, so that the risk of deterioration of the material is reduced, the quality and the performance of the material are ensured, and the turnover speed of the material can be accelerated.

This invention discloses a method and system for detecting and evaluating the settlement of buried pipelines based on ground-penetrating radar (GPR). The detection method acquires B-Scan mask images of shallow-buried pipelines, extracts the overall and local characteristics of target hyperbolic reflection signal feature points in the images, removes singular points, performs curve fitting on all valid target hyperbolic reflection signal feature points, and calculates and scores the depth and wave velocity values ​​corresponding to the target feature points to obtain the pipeline burial depth. The evaluation method, based on the pipeline settlement detection results, identifies the location of maximum settlement deformation by using the angle formed by the height change between two points on the pipeline, and predicts the location where the risk of fracture in the detected section may occur. The detection system implements this detection method, and the evaluation system implements this evaluation method. This application solves the problem in engineering measurements where hyperbolic reflection signals with characteristic damage caused by electromagnetic wave attenuation and coupling cannot be effectively calculated, significantly improving the data's processability and analyzability.
