Abstract
The present invention provides a mounting device and method of a tandem-type rock mass three-dimensional disturbance stress sensor, and the device is formed by sequentially connecting a head end unit, a plurality of repetitive units, and a tail end unit. This invention enables the accurate installation of multiple three-dimensional disturbance stress sensors within a single borehole without requiring full-hole grouting. As a result, the sensors can be mounted in a multi-point distributed arrangement within the same borehole. Adhesive fluid in a top adhesive cartridge is triggered through a head end triggering mechanism to bond a three-dimensional disturbance stress sensor in a first repetitive unit, and adhesive fluid in a corresponding first adhesive cartridge is triggered by using the first triggering mechanism to bond a three-dimensional disturbance stress sensor in a next repetitive unit, to ensure good coupling between the three-dimensional disturbance stress sensor and a rock mass.
