Problems solved by technology

Due to the characteristics of soft rock disintegrating in water, it often leads to the following problems: when the subgrade filled with soft rock encounters water, the overall stability of the subgrade will be reduced, and even the road surface will subside and collapse.
[0005] The disadvantage of the above test is that the disintegration process and the sieving process are separated, which will make the test process more complicated. In addition, it is impossible to make a timely judgment on the time when the disintegration basically stops, which will prolong the test time. The more times of sieving, the greater the mass loss of the sample, which will affect the accuracy of the test

Abstract

The invention discloses an automatic soft rock disintegration screening instrument and a testing method thereof. According to the automatic soft rock disintegration screening instrument, a transparent outer barrel (7) is arranged on a vibrating table; a water inlet pipe (10) is arranged on the high part of the transparent outer barrel (7); a water outlet pipe (8) is arranged on a low part of the transparent outer barrel (7); a plurality of transparent inner barrels (1, 2, 3, 4, 5, 6) are sequentially arranged inside the transparent outer barrel (7) from top to bottom; the bottom of each of the transparent inner barrels (1, 2, 3, 4, 5, 6) is provided with a screening hole (13); and the pore diameters of the screening holes (13) of the plurality of transparent inner barrels (1, 2, 3, 4, 5, 6) are sequentially reduced according to the standard lab screening hole sizes from top to bottom. According to the automatic soft rock disintegration screening instrument and the testing method thereof, the automatic soft rock disintegration screening instrument simultaneously performs the disintegration process and the screening process and is high in efficiency, intuitive, high in operability and low in error.

Description

technical field [0001] The invention relates to a high-efficiency automatic disintegration sieving instrument for soft rock disintegration test, in particular to a disintegration instrument used for disintegration of soft rock in the fields of roads and railways when encountering water. Especially the high-efficiency automatic sieving disintegration instrument for the soft rock disintegration test of the carbonaceous soft rock slope surface disintegrating in water and the roadbed filler in the carbonaceous soft rock area disintegrating in water under rainfall conditions, can effectively and truly reflect the The distribution of particle gradation after soft rock disintegration provides a basis for subsequent physical and mechanical experiments. The invention also relates to a test method of the automatic sieving instrument for soft rock disintegration. Background technique [0002] Soft rock disintegration refers to a phenomenon in which soft rock undergoes a series of phys...
