Description

TECHNICAL FIELD

[0001] The present application relates to the dam rolling technology field, specifically to a kind of for the rapid detection equipment of cushion material gradation in dam rolling process. BACKGROUND

[0002] Cushion material is a specific material in dam filling, and it needs to have good physical properties, such as hardness, good durability, and no clay and organic impurities. These properties are crucial to ensure the stability and durability of the cushion material, which is usually obtained by quarrying and processing, and has specific gradation and physical properties of granular material. It is mainly used near the downstream slope of the dam to prevent the loss of coarse and fine particles in the dam, and also serves to protect the dam body and provide stable support. Through reasonable gradation design, the cushion material can optimize the drainage performance of the dam, reduce water accumulation and water pressure in the dam body. During the filling process of the cushion material, strict quality control is required, such as testing the gradation, dry density and other indicators of the cushion material to ensure that it meets the design requirements.

[0003] However, in dam construction, the gradation of cushion material is crucial to the stability and durability of the dam. The traditional detection method takes a long time, and it is difficult to timely feedback the gradation of the cushion material, resulting in low construction efficiency, and it is difficult to accurately adjust the blasting parameters to meet the needs of the cushion material under different geological conditions. Therefore, it is particularly important to develop a system and method that can quickly and accurately detect the gradation of the cushion material and intelligently adjust the blasting parameters based on the test results. The stone particle size needs to be repeatedly screened by hand, and the tedious screening process requires a lot of time. Especially when dealing with a large amount of stone, low screening efficiency will directly lead to the extension of the production cycle, and more human resources need to be invested, which not only increases the labor cost, but also may further reduce the production efficiency due to insufficient manpower. In addition, ordinary manual screening of stone often leads to uneven particle size distribution, which affects subsequent processing and use effect. CONTENT OF THE UTILITY MODEL
