Embodiment Construction

[0011] The following describes the implementation of the present invention in detail with reference to the accompanying drawings, but they do not constitute a limitation of the present invention, and are merely examples. At the same time, the advantages of the present invention will become clearer and easier to understand.

[0012] With reference to the drawings, it can be seen that the rock soil humidification test device of the present invention includes a workbench 7, a cantilever support 1 fixed on the workbench 7, and a sample-containing grid 3 hung on the upper end of the cantilever support 1, and a sample-containing grid 3 The sample 6 is placed inside, the beaker 2 is placed on the electronic balance 4, the disintegrating liquid 5 (or deionized water) is placed in the beaker 2, and the electronic balance 4 is located on the lifting device 8 (which can be an electric lifting device or a manual lifting device ), the lifting device 8 is on the workbench 7. The diameter of the...

Abstract

A rock-soil wetting test device comprises a workbench (7), a cantilever bracket (1) fixed on the workbench (7), a sample holding grid frame (3) hanging at the upper end of the cantilever bracket (1), a test sample (6) put in the sample holding grid frame (3), a beaker (2) put on an electric scale (4), and a disintegration liquid (5) in the beaker (2), wherein the electric scale (4) is located on a hoisting device (8), and the hoisting device (8) is located on the workbench (7). The invention overcomes the extreme situation that the current research method mainly focuses on dry (baking)-wet (soaking) circulation and the defect of fewer research on intermediate state. The invention can carry out quantitative expression on the whole process of soil wetting with simple structure and convenient use.

Description

Technical field [0001] The invention relates to a humidification test device suitable for various rock and soil. Background technique [0002] Wetting of rock and soil refers to the phenomenon of its disintegration in water. In the construction and construction of water conservancy projects, the soil and rock masses used as building materials and foundations are directly in the atmosphere, and the environmental conditions are mainly affected by the action of water, causing them to be wetted, so that they are cracked, peeled or reduced in strength. If prevention or Improper handling will lead to a series of engineering problems. For example, the decompression wells and drainage holes of the dam foundation cause the sidewall rock and soil to collapse or collapse due to humidification, which reduces the benefit or completely fails. Slope instability caused by weathering and erosion of rock and soil slopes on reservoir banks is often also related to humidification. In addition, in th...
