[0021] The lower instrument comprises an outer tube 13, in which a heat insulator 11 and a measuring plate positioning assembly 12 are installed; an upper pulley joint 10 is installed at the upper end of the outer tube 13, and the outer tube 13 and the upper pulley joint 10 are connected by threads; an upper pulley arm 18 and an upper torsion spring 19 are installed on the upper pulley joint 10, and upper pulleys 16 are installed at both ends of the upper pulley arm 18; a quick connector 9 is installed at one end of the upper pulley joint 10 away from the outer tube 13, and a protective cap 8 is installed on the quick connector 9; an O-ring is installed between the quick connector 9 and the upper pulley joint 10; the protective cap 8 and the quick connector 9 are connected by threads; the wheel spacing (upper and lower pulleys) of the sliding inclinometer is a standard 500mm, and the high side of the pulley is the positive direction of the inclinometer during inclinometer measurement.
[0022] The lower end of the outer tube 13 is provided with a lower pulley joint 14, the outer tube 13 and the lower pulley joint 14 are threadedly connected, the lower pulley joint 14 is provided with a lower pulley arm 24 and a lower torsion spring 22, and the lower pulley 23 is provided at both ends of the lower pulley arm 24.

[0023] like Figure 2 and 5 The wheel spacing of the sliding inclinometer is standard 500mm. When measuring inclination, the high side of the pulley is the positive direction of the inclinometer. Two accelerometers are integrated inside, which can output the inclination data of the two axes A and B. The measuring axis of the A axis is consistent with the plane where the pulley is located, and the measuring axis of the B axis is perpendicular to the plane where the pulley is located. When the top of the instrument tilts in the "+" direction, the instrument displays a positive value; conversely, when the top of the instrument tilts in the "-" direction, the instrument displays a negative value.
[0024] During the inclinometer process, the probe is usually lowered to the bottom of the hole and then lifted up for measurement. The complete inclinometer process includes two rounds of forward measurement (0 direction) and reverse measurement (180 direction). The inclinometer tube has two perpendicular grooves in the A and B directions. In actual projects, the groove in the A direction of the inclinometer tube is usually aligned with the direction in which displacement may occur. Align the end of the probe marked with the "+" sign (the high side of the pulley) with the A0 direction and put it in. After the forward measurement is completed, the instrument is lifted out of the inclinometer tube. At this time, turn the instrument over and align the other end (the low side of the pulley) with A0 and put it in safely. (At this time, the "+" mark on the probe should be aligned with the A180 direction of the inclinometer tube).
