Abstract

The invention relates to a high-pressure low-temperature triaxial corrosion experimental device, and aims to provide a high-pressure low-temperature triaxial corrosion experimental device which is simple in structure and convenient to operate to provide experimental basis and basic data for accurately understanding deep karst development characteristics and provide scientific basis for subsequent necessary engineering supporting measures. The device is fixed on an experiment table, and is characterized by comprising a confining pressure bin seat riveted with the experiment table, a confining pressure bin cover fixedly riveted on the top of the seat, and an axial load server arranged above the bin cover, wherein the outside of the confining pressure bin seat has a circular truncated cone shape, and a hollow cylindrical confining bin is formed in the confining pressure bin seat; the confining pressure bin cover is a flat plate and is provided with a through hole of which the diameter is matched with that of a sample; and the axial load server consists of two cylinders with different diameters, and a pressure gauge is arranged in an upper cylinder with a large diameter and is communicated with the confining pressure bin below through a pipeline. The high-pressure low-temperature triaxial corrosion experimental device is suitable for underground engineering such as hydraulic and hydro-power engineering, traffic and mines.

Description

technical field [0001] The invention relates to a high-pressure and low-temperature triaxial corrosion experimental device and an experimental method thereof. It is suitable for underground projects such as water conservancy and hydropower projects, transportation, and mines. Background technique [0002] According to the characteristics of karst development in the project area and the needs of project construction, especially underground buildings, dam foundations, traffic tunnels or other rock and soil bodies (including artificial materials, such as concrete), due to long-term exposure to high-pressure seepage, corrosion, erosion, etc. The influence of the natural and operating environment of the rock and soil mass causes the comprehensive characteristics of rock and soil mass to change in the direction of its function and safety weakening over time. The interaction between water and the rock-soil mass under high pressure exists for a long time, causing micro-cracks in th...
