Multi-condition muddy-water seepage pressure-measuring device

Abstract

The invention relates to a multi-condition muddy-water seepage pressure-measuring device, belongs to the technical field of geotechnical engineering and environment engineering and is mainly used for researching influence of a stagnation effect of suspended matters to seepage. The multi-condition muddy-water seepage pressure-measuring device is used for indoor simulation of a muddy-water seepage process, the structure is simple, and the operation is convenient. The multi-condition muddy-water seepage pressure-measuring device comprises a muddy-water stirring mechanism, muddy-water flow control and measurement mechanisms, a lifting mechanism, pressure measuring mechanisms and a sample collection mechanism, wherein the muddy-water stirring mechanism is formed by a stirrer which is fixedly arranged on a stirring tank; the muddy-water flow control and measurement mechanisms are arranged below the muddy-water stirring mechanism and consist of guide pipes and flow meters; the lifting mechanism is arranged below the muddy-water flow control and measurement mechanisms and consists of support columns, support rods, fixtures, an upper chassis and a lower chassis; the pressure measuring mechanisms are arranged between the upper chassis and the lower chassis and consist of pressure measuring housings, manometers, sand filtering screens, earth columns, upper extension guide pipes and lower extension guide pipes; and the sample collection mechanism consists of a collection disc and a chassis.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering and environmental engineering, and in particular relates to a multi-working-condition muddy water seepage pressure measuring device, which is mainly used for the research on the influence of the silting effect of suspended matter on seepage. Background technique [0002] With the rapid development of China's social economy, the demand for mineral resources is also increasing sharply, and the scale of mining development is also increasing sharply. The safety issues involved in it have gradually attracted great attention and attention from the state and society in recent years. Tailings reservoir is a major hazard source of man-made debris flow with high potential energy. Its operation status is not only related to the economic benefits of mining enterprises, but also related to the safety of people's lives and property in the downstream of the tailings reservoir area and its surroun...
