Abstract
A split-type device for measuring rock mass deformation under high hydraulic pressure and a construction method and use thereof. Main components of the device include a metal measuring rod, a magnetic iron core, a shell, a waterproof coil framework, a coil, a tail accessory, a cable clamp, a cable, a signal processing bin, etc. Main electronic components are treated by adopting the all-metal shell and a vacuum particle sealing double-layer sealing process, and have hydraulic pressure resistance of 5 MPa or above. Measurement signals feature centralized processing, digitization and dual utilization of signals, i.e., after data of a plurality of sensors is processed in an electronic bin and then digitized signals are connected to an independent reader outside the bin or a centralized acquisition device for in-situ tests.
