Detachable variable parameter multifunctional testing apparatus

Abstract

The invention discloses a detachable variable parameter multifunctional testing apparatus which comprises a steel frame, a model box, an angle adjusting device, a horizontal loading device, a verticalloading device, universal wheels and a bottom plate, wherein the angle adjusting device comprises a base, a rotating shaft and an angle adjusting jack; one side of the bottom plate is hinged with oneside of the base by a group of rotating shaft, the other sides are hinged by a group of angle adjusting jack, and in test, angle adjustment is performed by using the angle adjusting jack; the steel frame is fixedly arranged outside the model box, the bottom of the model box is connected with the bottom plate by a high-strength bolt, the horizontal loading device is arranged on the side face, thevertical loading device is arranged at the top, the vertical loading device is connected with the model box by a mobile guide rail groove, and two groups of universal wheels with brake pads are symmetrically arranged on the lower bottom surface of the base, so that the loading device can be moved according to environment requirement. The detachable variable parameter multifunctional testing apparatus is simple in structure, economical and reasonable, convenient to operate, high in testing efficiency, and applicable to testing research on side slope geotechnical engineering.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a multi-angle loading device which can be used in geotechnical engineering to change the slope gradient of a test. Background technique [0002] As a common natural disaster, landslide not only restricts the economic development of our country, but also poses a serious threat to the life and property of the people. The factors causing the landslide mainly come from two aspects. The internal factor is the change of some characteristics of the soil itself, and the external factor is the impact of rainfall, earthquake, human engineering activities, etc. The root cause is the effect of load. [0003] The traditional test loading device is relatively simple, mostly a single loading method, however, slope instability mostly occurs under the action of multiple loads. Therefore, the existing slope loading device cannot reasonably explain the slope failure under the comp...

Problems solved by technology

[0003] The traditional test loading device is relatively simple, mostly a single loading method, however, slope instability mostly occurs under the action of multiple loads

Therefore, the existing slope loading device cannot reasonably explain the slope failure under the comprehensive load, and the test efficiency and practicability are low

The loading method of the existing slope loading device is relatively simple, which cannot explain the failure mechanism of the comprehensive action of the slope, and the loading device cannot be disassembled, and the operation is troublesome
