opening a water inlet, and injecting water into the water supply tank to a water level indicating plate;
starting an electric push rod to push a cutting table filled with an undisturbed core sample to a position below the water level of a large water tank, and sealing an opening of the large water tank by a first cover plate connected with the electric push rod;
starting an electric push rod, pushing a cutting motor to a water tank, enabling a double-blade at the bottom of the cutting motor to enter the large water tank from a blade hole in a first cover plate, sealing the blade hole through a protection plate connected with the cutting motor through a spring, and sealing the whole large water tank;
starting a cutting motor to cut the core sample with the standard length;
taking the core sample from the cutting table, and installing and fixing the core sample on the rotary cutting table according to the steps;
starting an electric push rod to push the rotary cutting table to the position below the water surface of the small water tank, and sealing an opening of the small water tank by a second cover plate connected with the electric push rod;
starting a descending switch of the core drill, pushing the core drill with the core bit to the small water tank, and enabling the core bit to enter the small water tank through the blade hole in the second cover plate;
starting a core drilling machine to drive a core cutter head to rotate at a high speed to cut into a core sample, and finishing sample cutting when the core cutter head enters a core groove;
and then taking off the cut core sample with standard length and diameter, and finishing the whole sample preparation work.
