Equipment used: fixed inclinometer, vibrating wire osmometer, ABS inclinometer, 8-channel mixed acquisition instrument, wireless communication module, solar power supply system and special accessories.
Project Background
The street of Zhengzhi Town in Bazhong is built on the slope, and the risk of landslide is high. There are residential buildings on both sides, which has great potential safety hazards.
Construction
Select the area with high landslide risk as the monitoring point on site, and bury the inclinometer after drilling. One group of guide grooves of the inclinometer shall be aligned with the soil displacement direction. First, place the osmometer at the bottom of the hole. Note: the soil seepage pressure shall be monitored at the same time when monitoring the soil landslide displacement project. Because the number of inclinometers in each hole is not large, separate leads are adopted. If the number of inclinometers in the hole is large, the series connection mode must be considered, so that only one wire is drawn from the hole and the acquisition instrument only occupies one channel, which is relatively cost-saving and relatively convenient for on-site installation. The inclinometer is connected by 6mm stainless steel rod, which not only has toughness to ensure deformation with the soil in case of landslide, but also can ensure smooth lowering. After the inclinometer is installed, the lead wire is connected to the channel of the acquisition instrument. The 8-channel acquisition instrument is a built-in wireless module, and only a solar connector and a signal antenna connector need to be connected to the outside.
