In this embodiment, the upper surface of the ground monitoring pier 18 is parallel to the ground, and the plane where the rotating platform 12 is located is parallel to the plane where the upper surface of the ground monitoring pier 18 is located.

In this embodiment, the support 1 is installed on the ground monitoring pier 18 to fix the measuring device on the ground monitoring pier 18 to prevent the measuring device from moving. The upper surface of the ground monitoring pier 18 is built horizontally. That is the azimuth and inclination angle of the slope, preferably, the support frame 2 can be composed of two support plates 1 parallel up and down and a support plate 2 vertically connecting the two support plates 1, and the azimuth measuring mechanism is arranged on The top of the support frame 2 is set on the upper support plate one of the two parallel support plates one, so that the surveyor can directly observe whether the slope has tilted, so as to detect landslide geological disasters and surface subsidence geological disasters in time. Then analyze the inclination of the slope, and strive for evacuation time for the occurrence of geological disasters. The inclination measuring mechanism is arranged between two support plates, which limits the structural size of the inclination measuring mechanism. The rotating bolt 13 is rotatably installed on the supporting frame On the inner bottom surface of 2, that is, the lower support plate is to provide the lower rotation point for the inclination measuring mechanism, and the connecting hose 7 passes through the top plate of the support frame 2, which is to pass through the upper support plate.

Described azimuth measurement mechanism comprises installation platform 3 and the circular level bubble 6 that is arranged on installation platform 3 and compass 5, and reference pointer 16 and compass 17 are arranged in compass 5, and the setting of installation platform 3 is in order to further adjust described inclination angle The installation state of the measuring mechanism ensures that the installation of the inclination measuring mechanism is horizontal, prevents the circular level bubble 6 and the compass 5 from being directly installed on the upper support plate 1 and cannot separately adjust the installation state of the inclination measuring mechanism, reduces installation time and reduces Measurement error, thereby converting the azimuth angle of measuring the inclination of the ground monitoring pier 18 into measuring the azimuth angle of the compass 5, since the compass 5 itself has an angle scale, the initial azimuth α of the ground monitoring pier 18 measured by the reference pointer 16 and the compass 17 can be determined ;

The level bubble 6 quickly observes the horizontal state of the installation platform 3 .

In this embodiment, the length of the rotating pointer 8 is smaller than the ring width of the dial 9 . The rotating pointer 8 indicates data within the ring width of the dial 9, and the installation position of the rotating pointer 8 limits its length to be smaller than the ring width of the dial 9, so as to prevent the rotating pointer 8 from colliding with the dial 9 when the rotating ring 10 rotates.

In this embodiment, the straight line where the rotating pointer 8 is located is perpendicular to the straight line where the cylindrical level 2 14 is located. When the inclination measuring mechanism is leveled, the cylinder level 2 14 is adjusted to be in a horizontal state.

The use method of the present utility model is as follows: drill holes downward at the edge of the slope and pour concrete into the hole to form a ground monitoring pier 18 connected with the slope; the upper surface of the built ground monitoring pier 18 is initially horizontal, which is convenient When the body is inclined, measure the inclination of the upper surface of the ground monitoring pier 18, thereby measuring the inclination of the slope body; install the measuring device on the ground monitoring pier 18, and fix the bracket 1; adjust the cylinder level by rotating the bolt 13. Move in the direction until the bubble is centered, adjust the rotating ring 10 so that the rotating pointer 8 is at the 0 position; rotate the adjusting bolt 4 to center the circular level bubble 6; after the measuring device is leveled, record the current N direction of the compass 17 and the direction of the compass 5 Relative position, record the included angle of the counterclockwise direction of the N direction of current reference pointer 16 and compass 17 simultaneously, determine slope body initial azimuth angle α; Observe whether the bubble in the slope body initial azimuth angle α and cylindrical level two 14 shifts, When the initial azimuth α of the slope body and the air bubbles in the second 14 of the cylindrical level do not deviate, it means that the slope does not change in inclination, and continue to observe the changes of the measuring device; Time shifting indicates that the slope changes, and the relative position of the compass 17 and the compass 5 after the slope is recorded is recorded, and the angle between the reference pointer 16 and the counterclockwise direction of the compass 17 in the N direction is recorded at the same time to determine the slope. Back azimuth α', according to the formula Δα=α-α', calculate slope body azimuth variation Δα, obtain the N direction angle of slope body deviation compass 17, the N direction angle of slope body deviation compass 17 is slope body deviation Shift the azimuth angle; rotate the rotating platform 12 by rotating the bolt 13 in its plane along the level bubble in the cylinder level-11 and rotate along the descending direction, and keep the plane where the rotating platform 12 is located and the slope body inclined ground monitoring pier 18 upper surface The relative position of the plane remains unchanged until the rotation of the rotating platform 12 is stopped until the air bubbles in the two parallel cylindrical levels-11 are centered. At this time, the bubbles in the two cylindrical levels-11 are centered and the rotating pointer 8 is at 0 position. The bubble of the cylinder level 2 14 is not centered; turn the rotating ring 10 until the bubble in the cylinder level 2 14 is in the center, at this time, the rotating pointer 8 points to the scale on the dial 9 is the angle that the cylinder level 2 14 has turned, and the cylinder level 2 14 has turned the angle The angle is the inclination angle β of the slope body.

When actually measuring the inclination angle β of the slope body, as shown in Figure 4 and Figure 5, the inclination angle of the ground monitoring pier 18 is accompanied by the change of the azimuth angle of the ground monitoring pier 18 when measuring the ground monitoring pier 18, and the inclination angle of the ground monitoring pier 18 is The included angle between the plane where the surface is located and the plane where the horizontal ground is located. That is, the angle between surfaces. Since the rotating platform 12 is parallel to the upper surface of the ground monitoring pier 18 in real time, the inclination angle of the ground monitoring pier 18 can be obtained by obtaining the angle between the rotating platform 12 and the horizontal plane. Since the ground monitoring pier 18 follows the The slope body is tilted, and the air bubbles in the two cylinder level one 11 and the cylinder level two 14 on the rotating platform 12 are offset, and the rotating platform 12 is rotated in its plane by rotating the bolt 13 until it is parallel The two cylinder levels one 11 are horizontal, at this moment, one cylinder level one 11 in the two cylinder levels one 11 is positioned at a high position to maintain the level, and the other cylinder level one 11 in the two cylinder levels one 11 is positioned at a low position to maintain the level, and both The horizontal position of the cylindrical level-11 is unique. Since any straight line on the horizontal plane is in a horizontal state, the intersection line between the extension line of the rotating platform 12 and the horizontal plane must be in a horizontal state, so the cylindrical level-11 located at a low position and kept horizontal can be seen. It is the intersection line between the plane where the rotating platform 12 is located and the horizontal plane. The cylindrical level 2 14 inclined with the dial 9 is perpendicular to the cylindrical level 1 11 that is positioned at a low position and remains horizontal. At this time, turn the rotating ring 10 to make the cylindrical level 2 14 horizontal. 9. Installed vertically on the rotating platform 12, the leveled cylindrical level 2 14 can be regarded as a straight line on the horizontal plane perpendicular to the low and horizontal cylindrical level 1 11. Therefore, the angle at which the cylindrical level 2 14 turns is ground monitoring The inclination angle of the pier 18, the inclination angle of the ground monitoring pier 18 is the inclination angle β of the slope body, and the azimuth and inclination angle obtained through the measurement can reflect the inclination of the slope.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical essence of the present utility model still belong to Within the scope of protection of the technical solution of the utility model.
