Description

Technical Field

[0001] The utility model belongs to the field of rock water absorption tests, and particularly relates to an automatic rock water absorption test device. Background Technique

[0002] Rock water absorption is one of the physical and mechanical properties of rocks, which can reflect the ability of rocks to absorb water. Rock water absorption and saturated water absorption rate can effectively reflect the development degree of microcracks in rocks, and can be used to judge the frost resistance and weathering resistance of rocks. The number of test specimens used in the rock water absorption test should not be less than 3 pieces. The rocks are all immersed in water and freely absorb water for 48 hours. The natural water absorption rate is the ratio of the maximum weight of water absorbed by the rock specimen under the action of atmospheric pressure to the dry weight of the specimen. The water absorption rate of rocks depends on the number, size and opening degree of the pores and fissures contained in them. Therefore, the rock water absorption rate can effectively reflect the development degree of pores and fissures in rocks and become an important index for evaluating the properties of rocks. However, the existing test devices require manual operation and water addition every two hours. The original test water addition interval can last for 6 hours. Since manual water addition can only visually estimate the approximate height, the accuracy of rock water absorption is reduced.

[0003] Therefore, in view of the deficiencies of the above solutions in actual production and implementation, they are corrected and improved. At the same time, in the spirit of seeking excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created to provide an automatic rock water absorption test device to solve the problems.
