Property modulus, conventional method is boring elastic modulus instrument method, and boring elastic modulus instrument is on popping one's head in thousand jin of micro hydraulic top with installing,
The stress axle two ends of jack are connected with a pair semicircle bearing plate, and install corresponding displacement meter, by the pressurization on ground
Oil pump applies one group of pressure, reads corresponding shift value simultaneously, calculates the deformation of rock mass by corresponding elastic deformation formula
Modulus and elastic modelling quantity, the shortcoming of this measuring method is：Using hydraulic jack volume big, need oil pipe and in the hole probe phase
Connect, test site equipment is many, program is numerous and diverse, because boring mostly is small-bore exploratory hole, miniature thousand jin of pressure on top surface is difficult to surpass
30Mpa is it is impossible to test hard rock.
Utility model content
This utility model aims to provide a kind of boring of ultra-magnetic telescopic and becomes mould measuring probe, with solve existing for geology brill
Hole come to test different depth rock mass deformation modulus and elastic modelling quantity when existing hydraulic jack volume is big, test site sets
Standby many, program is numerous and diverse, the problems such as cannot test hard rock.
This utility model is achieved by following technical solution：
A kind of ultra-magnetic telescopic boring becomes mould measuring probe, including shell, is provided with horizontal super mangneto and stretches in the middle part of shell
Contracting bar, ultra-magnetic telescopic bar outer wall is enclosed with excitation coil, and ultra-magnetic telescopic bar two ends are mounted on metal pedestal, and metal pedestal is close
One end of ultra-magnetic telescopic bar is mounted on travelling gear, also includes two motors, it is upper and lower that motor is separately mounted to excitation coil
Both sides, motor output end is power transmission shaft, and transmission shaft end is connected with the driving gear being meshed with described travelling gear, metal pedestal
Outer end is provided with telescopic bearing plate, and bearing plate is threaded connection with metal pedestal, and bearing plate is provided with pressure in the middle part of outer end
Sensor, inside the shell is provided with wire, and wire is connected with two motors, two pressure transducers and excitation coil successively.
