step D: injecting high-pressure water into the water inlet pipe (3), wherein the high-pressure water is divided into two parts by the water delivery pipe (4);
step E: one strand of high-pressure water is injected into the closed space through an opening at one end of the water conveying pipe (4), and the other strand of high-pressure water flows to the first piston (6) through the water conveying pipe (4) and pushes the first piston (6) to move directionally;
step F: the track measuring instrument probe (7) is used for measuring the track in the closed space; and after the measurement is finished, discharging the high-pressure water in the water conveying pipe (4), and recovering the first piston (6) to the initial position.
