  • High-efficiency pre-drilling pressure meter test apparatus and method for deep rock mass
    Patent number: 10914164
    Abstract: A high-efficiency pre-drilling pressure meter test apparatus for deep rock mass includes a rigid drill pipe, a probe, a pressurizing device and a signal processing device. The rigid drill pipe, comprising a top end and a tail end opposite to the top end, receives a fluid medium. The probe is connected with the tail end of the rigid drill pipe and communicates with the rigid drill pipe. The probe includes a measuring chamber. The fluid medium flows from the rigid drill pipe to the measuring chamber. The pressurizing device is connected to the top end of the rigid drill pipe and applies pressure to the fluid medium. The signal processing device is electrically connected with the probe to detect deformation of the measuring chamber with the change of the pressure and volume of the fluid medium in the pressurizing device.
