Embodiment Construction

[0030] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0031] Such as figure 1 , 2 As shown, a tailings microscopic mechanical and deformation observation test device includes a pressure chamber 2 fixed on the base 1, and a pressurizing piston 3 extending from the mouth of the pressure chamber 2 into the pressure chamber 2, and The pressurizing piston 3 is tightly matched with the pressure chamber 2, and a pressure chamber is formed in the pressure chamber 2. The key is that: the side wall of the pressure chamber 2 is provided with an observation window 2a, and the inner wall of the pressure chamber 2 is provided with a ring for installation Groove, transparent observation tube 4 is installed in this mounting groove.

[0032] Using an electron microscope, the deformation of the microstructure of the tailings in the pressure chamber under pressure can be observed through the observation window 2a.

Abstract

The invention discloses an observation test device for the mesoscopic and microscopic mechanical property and deformation of tailings, which comprises a pressure bin fixed on a base and a pressurizing piston extending into the pressure bin from a cylindrical opening of the pressure bin, wherein the pressurizing piston is matched with the pressure bin hermetically; and a pressure cavity is formed in the pressure bin. The observation test device is characterized in that: an observation window is formed on the side wall of the pressure bin; a circle of installation groove is formed on the inner wall of the pressure bin; and a transparent observation cylinder is arranged in the installation groove. The observation test device has the advantage that the deformation condition of mesoscopic and microscopic structures of the tailings in the integral compressed process can be observed.

Description

technical field [0001] The invention relates to a pressure deformation observation device, in particular to a tailings microscopic mechanics and deformation observation test device. Background technique [0002] The traditional geotechnical deformation monitoring device is to fix the pressure chamber on the base, and the pressurized piston extending from the mouth of the pressure chamber into the pressure chamber, and the pressurized piston and the pressure chamber are tightly matched, and the pressure chamber A pressure chamber is formed inside. [0003] When inspecting the deformation of the rock and soil, put the rock and soil into the pressure chamber, and then pressurize the rock and soil through the pressurized piston. After the pressurization, take out the pressurized piston to detect the change of the rock and soil in the pressure chamber. [0004] The defect of the prior art is that only the change of the rock and soil after pressurization can be observed, and the ...
