Acoustic wave method measuring device for full-section loose circle of roadway and chamber and using method of acoustic wave method measuring device

The invention provides a roadway and chamber full-section loose zone sound wave method measuring device and a using method, and belongs to the technical field of mining industry and geotechnical engineering surrounding rock loose zone testing, and the device mainly comprises a sound wave testing host, a one-transmitting double-receiving sound wave testing probe assembly, a hollow connecting rod, a hole sealing assembly, a three-way connector assembly, a water injection assembly and an exhaust assembly. Through close cooperation of the hollow connecting rod hole sealing assembly, the three-way connector assembly, the water injection assembly and the exhaust assembly, convenient and fast injection, maintaining and sealing of a sound wave testing coupling agent-water in an inclined or vertically upward drill hole and continuous measurement of a one-transmitting-double-receiving sound wave testing probe can be effectively achieved, and therefore full-section loose circle measurement is achieved. According to the
