The invention discloses pressurized water experiment equipment based on
coal body or rock-body loose circle detection. The equipment comprises a
test probe, a drilling
machine, a drilling rod and a control operation bench. The
test probe comprises a connection
pipe. The connection
pipe is arranged along a
drill hole. A front portion, a middle portion and a
tail portion of the connection
pipe are provided with a front portion plugging device, a middle portion plugging device and a
tail portion plugging device. When a plugging cavity is filled with water, the front portion plugging device, the middle portion plugging device and the
tail portion plugging device separate the
drill hole so as to form a number one water injection cavity and a number two water injection cavity. The drilling
machine is connected to the
test probe through the drilling rod so as to lengthen and advance the test probe to a designated area. The control operation bench comprises a
high pressure flexible pipe. The control operation bench is connected to the drilling
machine through the
high pressure flexible pipe. In the invention, integration of plugging and testing of the test probe is realized, the number ofpipelines which work simultaneously in the
drill hole is reduced, a problem of mutual intertwining of multiple pipelines in the
drill hole during an advancement process is solved, and stability of a measurement process of a rock
mass damage range is improved.
