Multi-angle injection device for detecting strength of soft rock and soil slope and use method thereof

Abstract

The invention relates to a multi-angle injection device for detecting strength of soft rock and soil slope and a use method thereof, test objects are the soft rock and the soil slope. The multi-angle injection device comprises a mechanical structure, a penetration device, a control device and a power module, the mechanical structure is used for connecting and fixing the penetration device and the control device, and the control device controls the penetration device and collects, processes and stores detection data through a computer program. The use method thereof comprises the following steps: counterweights on two sides of the vertical support frame are hung; a power supply is connected; test parameters are set, and the initial penetration resistance and the penetration depth are zeroed; a forward button on the control panel is pressed down, the probe and the probe rod penetrate into the test slope at a constant speed, and the soil body acts on the pressure sensor during penetration; during testing, penetration resistance and penetration depth data are collected; according to an empirical formula, physical and mechanical property indexes of the soft rock and the soil slope can be calculated by utilizing test data; and multi-height, multi-depth and multi-angle penetration is realized through a height adjusting guide rail and a rotating bearing.

Description

technical field [0001] The invention belongs to the field of geotechnical engineering investigation equipment, and in particular relates to a multi-angle penetrating device for detecting the strength of soft rock and soil slopes and a use method thereof, which are suitable for on-site in-situ detection of the strength of soft rock and soil slopes. Background technique [0002] Soft rock and soil slopes are widely developed in northern my country, and geological disasters such as landslides, collapses, and dumps frequently occur in areas where soft rock and soil slopes develop. Due to the expansion of the number and scale of human activities such as railway engineering, tunnel engineering, and water conservancy projects near soft rock and soil slopes, the number and frequency of geological disasters on soft rock and soil slopes have continued to increase. The occurrence of geological hazards on soft rock and soil slopes depends on slope shape factors and inducing factors such...

AI Technical Summary

Problems solved by technology

However, judging from the disclosed technical characteristics, the device cannot adjust the penetration angle and cannot effectively capture the anisotropy of the slope soil

At the same time, the device does not propose the reaction device required for in-situ testing on site, and the existing mechanical mechanism alone cannot be used for in-situ testing of slope strength.
