Slope displacement monitoring device

Abstract

The invention relates to the field of landslide monitoring equipment, in particular to a slope displacement monitoring device. It includes: including: an inclinometer tube, a power supply, and a wireless data transmitting device; the inclinometer tube is vertically inserted into the soil layer of the slope, and extends downward until the lower end of the inclinometer tube is inserted into the bedrock layer of the slope, through The bedrock layer secures the inclinometer pipe. Through a structure, both slope water content monitoring and slope displacement monitoring can be achieved, providing more comprehensive early warning data for slope embankment stability.

Description

technical field [0001] The invention relates to the field of slope monitoring equipment, in particular to a slope displacement monitoring device. Background technique [0002] The side slope refers to the slope with a certain slope on both sides of the roadbed to ensure the stability of the roadbed. The issue of slope stability has attracted much attention. There are many factors that affect slope stability, such as: the type and nature of rock and soil that make up the slope, the geological structure of the slope, the shape of the slope and groundwater, climatic conditions, weathering However, the most common factors affecting slope stability are climatic conditions and groundwater. For example, rainwater causes shale or interlayer soil (expansive soil) to expand, slope drainage is not smooth, and rainwater scours the slope. Cause slope collapse, abundant groundwater, long-term immersion leads to collapse of slope footing. [0003] The existing slope inclinometers have hi...

The issue of slope stability has attracted much attention. There are many factors that affect slope stability, such as: the type and nature of rock and soil that make up the slope, the geological structure of the slope, the shape of the slope and groundwater, climatic conditions, weathering However, the most common factors affecting slope stability are climatic conditions and groundwater. For example, rainwater causes shale or interlayer soil (expansive soil) to expand, slope drainage is not smooth, and rainwater scours the slope. Cause slope collapse, rich groundwater, long-term immersion leads to collapse of slope footing

[0003] The existing slope inclinometers have high measurement accuracy and can also realize automatic monitoring. However, due to the limitation of the measurement principle, the measurement range of the inclinometer is limited. In the case of large displacement changes on the sliding surface of the slope, The measurement cannot be continued, the sensor of the inclinometer is arranged in the borehole for measurement, and the sensor device is connected with the data acquisition device through a data line. When the sliding surface breaks the inclinometer tube, the monitoring cannot be continued; Inclinometers can only monitor slope displacement alone, but cannot monitor slope water content or monitor both slope displacement and water content through the same structure
