Integrated Engineering Anchor Stress Gauge Measuring and Reading Device

Abstract

The invention relates to an integrated engineering bolt stress gauge measuring and reading device. It consists of anchor rod stress gauge, strain gauge manual measurement and reading box, strain gauge automatic data acquisition box and measurement and reading conversion device. The cable clamp and the installation head of the measuring and reading line are composed of the anchor rod strain gauge through the signal line respectively connected to the outgoing line signal line clamping sleeve in the measuring and reading conversion device, the manual measuring and reading box of the strain gauge or the automatic data acquisition box of the strain gauge through the signal line The wires are respectively connected to the measuring and reading line signal line card sleeves in the measuring and reading conversion device. The device supports the automatic and manual conversion of the geotechnical engineering bolt stress gauge test reading, overcomes the single defect of the previous measurement and reading method, is not limited by space, environment, and signal, has a wide range of adaptation, high efficiency, and can be widely used in various fields. In the process of measuring and reading the bolt stress gauge data of similar underground geotechnical engineering.

Description

technical field [0001] The invention relates to an integrated engineering bolt stress gauge measuring and reading device, which can be widely used in geotechnical engineering for free switching between automatic data collection and manual data collection during data reading of bolt stress gauges. Background technique [0002] The research objects of geotechnical engineering are complex geological bodies that have gone through a long geological age. These geological bodies are in a stable state under certain time and conditions. When affected by natural or human factors, the equilibrium state is destroyed, and a series of landslides will occur. , collapse, subsidence and other geological disasters. With the increase in buried depth and scale of the project, deep engineering geological disasters such as rock bursts and landslides have become more frequent, larger in scale, and more destructive, seriously threatening the construction of the project and the safety of people's li...

AI Technical Summary

Problems solved by technology

[0004] Although the methods of manual and automatic data reading are very mature, these two methods can only be used alone, and the process of switching from one method to the other is quite cumbersome. When the automatic data collection signal is interrupted, it needs to be changed to manual collection. When the junction box needs to be re-installed and the signal line connected to the junction box; in addition, due to the engineering construction environment and conditions, when the junction box cannot be installed or the transmission signal can be automatically measured, the measurement and reading of the data becomes particularly troublesome. When the number of bolt stress gauges to be monitored is large, it often requires data collection personnel to spend a lot of time on the connection of signal lines, which is inefficient and wastes manpower and material resources
