Integrated engineering anchor pole strain gauge measuring and reading device

Abstract

The invention relates to an integrated engineering anchor pole strain gauge measuring and reading device. The device comprises an anchor pole strain gauge, a manual strain gauge measuring and reading box, a strain gauge automatic data acquisition box and a measuring and reading conversion device, wherein the measuring and reading conversion device is composed of an outlet connection line installation head, an outlet connection line signal wire clamp sleeve, an measuring and reading signal line clamp sleeve and a measuring and reading line installation head. The anchor pole strain gauge is connected to the outlet connection line signal wire clamp sleeve of the measuring and reading conversion device through signal wires respectively. The manual strain gauge measuring and reading box or the strain gauge automatic data acquisition box is connected to the measuring and reading signal line clamp sleeve of the measuring and reading conversion device through signal wires respectively. The device supports the free conversion of geotechnical anchor strain gauge test readings from the automatic mode to the manual mode, overcoming the shortcoming of the previous method whose reading means is a single and has flaws. Free from impact of space, environment, and signal, the device of the invention can be widely applied. For its high efficiency, it can be widely used in various geotechnical anchor strain gauge test readings.

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 conversion between automatically collected data and manually collected data when measuring and reading bolt stress gauge data. Background technique [0002] The research object of geotechnical engineering is complex geological bodies that have passed 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 of the buried depth and scale of the project, the occurrence frequency of deep engineering geological disasters such as rock bursts and landslides has become higher, the scale has become larger, and the damage has become stronger, which seriously thre...

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
