Embodiment Construction

[0011] Below, the accompanying drawing that connects to form is described further again to technical solution of the present invention:

[0012] Such as figure 1 As shown, a soil disintegration tester is composed of a scale 1, a bubble 2, a lead particle 3, a hanging frame 4, a screen 5, a graduated glass container 6 and a soil sample 7. The buoyancy device formed by connecting the scale 1, the buoy 2 and the suspension frame 4 is placed in a graduated glass container 6, the lower end of the scale 1 is connected to the upper end of the buoy 2, and the suspension frame 4 is tied at the junction of the scale 1 and the buoy 2 The buoyant bubble 2 is placed in the suspension frame 4, the buoyant bubble 2 is equipped with lead grains 3, so that the whole instrument can stand upright and float in the liquid; the bottom of the suspension frame 4 is equipped with a screen 5, and the soil sample 7 is placed on the screen 5.

[0013] Fill the graduated glass container 6 with water, put...

Abstract

The invention relates to a soil disintegration tester, comprising a scale, a blister, lead shots, a hanging frame, a screen, a glass container with a scale, and a soil sample, wherein a buoyancy device formed by connecting the scale, the blister and the scale is arranged into the glass container with the scale, the lower end of the scale is connected with the upper end of the blister, the hanging frame is tied on a connecting place between the scale and the blister, the blister is arranged into the hanging frame, the lead shots are arranged in the blister, the screen is distributed at the bottom of the hanging frame, and the soil sample is arranged on the screen. The soil disintegration tester, provided by the invention, has the advantages of simple structure, convenience for use and maintenance, and capability of accurately measuring three main disintegration indexes: a disintegration time, a disintegration characteristic and a disintegration speed. The soil disintegration tester can be widely applied to scientific studies about engineering geology and geotechnical engineering, teaching practice and production field.

Description

technical field [0001] The invention relates to an instrument for soil disintegration test. Background technique [0002] The disintegration property of soil due to immersion in water is called the disintegration property of soil. The disintegration forms of soil are various, including uniform granular, scaly, fragmented and so on. The disintegration of the soil is due to the unbalanced situation of water entering the pores or cracks after the soil is soaked in water, which causes the water film formed by the connection between the particles to thicken at different speeds, resulting in an unbalanced situation where the repulsive force between the particles exceeds the suction force, resulting in stress Concentrate, so that the soil collapses along the largest surface where the repulsive force exceeds the suction force. The three main indicators for evaluating the disintegration of cohesive soil are: disintegration time, disintegration characteristics and disintegration spe...
