Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, a rapid measuring device for slope inclination according to the present invention includes a bracket 1 installed on the ground monitoring pier 18, a support frame 2 installed on the bracket 1, and a set of In the support frame 2, an inclination angle measuring mechanism for measuring the change of slope inclination angle and an azimuth angle measuring mechanism arranged at the top of the support frame 2 for measuring the change in the azimuth angle of the slope body. The azimuth angle measuring mechanism includes an installation platform 3 and a The circular level bubble 6 and the compass 5 on the installation platform 3, a reference pointer 16 and a compass 17 are arranged in the compass 5, the installation platform 3 is fixed on the top of the support frame 2 through a plurality of adjustment bolts 4, and the inclination measuring mechanism includes a rotating platform 12 and a dial 9 vertically mounted on the rotating platform 12 with a scale, and two cylindrical levels 11 that are perpendicular to and parallel to the plane on which the dial 9 is located on the rotating platform 12, and the bottom end of the rotating platform 12 is rotated by rotating The bolt 13 is rotatably installed on the inner bottom surface of the support frame 2, the top of the dial 9 is provided with a connecting hose 7, the connecting hose 7 passes through the top plate of the support frame 2 and is connected to the bottom of the installation platform 3, and the connecting hose 7 passes through the support The extension line of the frame 2 coincides with the axial centerline of the rotating bolt 13, the dial 9 is a hollow annular structure, the inner ring of the dial 9 is provided with a rotating ring 10, the outer ring of the rotating ring 10 is provided with a rotating pointer 8, and the rotating ring 10 Two fixed plugs 15 are arranged symmetrically along the diameter direction of the inner ring of the inner ring, and a cylindrical level II 14 is installed on the two fixed plugs 15 .

In this embodiment, the bracket 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. That is, the azimuth and inclination of the slope. Preferably, the supporting frame 2 can be composed of two supporting plates 1 that are parallel up and down and a supporting plate 2 that vertically connects the two supporting plates 1. The azimuth angle measuring mechanism is arranged at The top of the support frame 2 is set on the upper support plate one of the two parallel support plates one, in order to facilitate the surveyor to directly observe whether the slope is inclined, so as to detect the landslide geological disaster and the surface subsidence geological disaster in time. Then analyze the inclination of the slope, and obtain evacuation time for the occurrence of geological disasters. The inclination measurement mechanism is arranged between two support plates, which limits the structural size of the inclination measurement mechanism. The rotating bolt 13 is rotated and installed on the support frame. The inner bottom surface of 2, that is, the lower support plate, is to provide the lower rotation point for the inclination angle measuring mechanism, and the connecting hose 7 passes through the top plate of the support frame 2, that is, passes through the upper support plate. The measuring mechanism provides an upper rotation point, and the extension line of the connecting hose 7 passing through the support frame 2 coincides with the axial centerline of the rotating bolt 13 to define the rotation axis of the inclination measuring mechanism, thereby determining the inclination measuring mechanism. installation location.

The azimuth angle measurement mechanism includes an installation platform 3, a circular level bubble 6 and a compass 5 arranged on the installation platform 3, a reference pointer 16 and a compass 17 are arranged in the compass 5, and the installation platform 3 is set to further adjust the inclination angle. The installation state of the measuring mechanism ensures the installation level of the inclination measurement mechanism, prevents the circular level bubble 6 and the compass 5 from being directly installed on the upper support plate 1 and cannot adjust the installation state of the inclination measurement mechanism independently, reduces the installation time and reduces the Therefore, the azimuth angle of the ground monitoring pier 18 is converted into the azimuth angle of the measuring compass 5. Since the compass 5 itself has an angle scale, the initial azimuth angle α of the ground monitoring pier 18 measured by the reference pointer 16 and the compass 17 can be determined. .

The dial 9 with scales is vertically installed on the rotating platform 12 , and the two cylindrical levels 11 , which are arranged in parallel on the rotating platform 12 , are perpendicular to the plane where the dial 9 is located. The dial 9 is set as a hollow annular structure so that the rotating ring 10 on the inner ring rotates along the radial direction of the dial 9, so as to determine the rotation track of the rotating pointer 8 on the outer ring of the rotating ring 10, and the two fixed plugs 15 rotate along the The diameter direction of the inner ring of the ring 10 is symmetrically arranged to facilitate the installation of the second cylindrical level 14. At the same time, it is determined that the second cylindrical level 14 is coplanar with the dial 9, and the two cylindrical levels one 11 are perpendicular to the plane of the dial 9 in order to be perpendicular to the dial. For any straight line on the surface of 9, the second cylindrical level 14 is located in the plane of the dial 9, thus confirming that the cylindrical level one 11 is perpendicular to the cylindrical level two 14, and the measurer adjusts the cylindrical level one 11 and the cylindrical level two 14 which are perpendicular to each other. All reaching the level is to adjust the level of the plane where the rotating platform 12 is located, so as to convert the inclination angle of the measuring ground monitoring pier 18 into the inclination angle of the measuring rotating platform 12, and then analyze the slope of the slope.

In this embodiment, the number of the adjusting bolts 4 is at least three.

Two support plates one (upper support plate one and lower support plate one) are arranged in parallel to provide the azimuth angle measuring mechanism disposed on the upper support plate one and the azimuth angle measurement mechanism disposed between the two support plates one. The inclination measuring mechanism provides an installation foundation, avoids introducing large errors into the measurement work due to different installation foundations, and reduces the time for leveling adjustment. 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 line where the rotating pointer 8 is located is perpendicular to the line where the second cylindrical level 14 is located. When the inclination measuring mechanism is leveled, the cylindrical level 2 14 is adjusted to be in a horizontal state. In actual use, since the dial 9 with a scale is vertically installed on the rotating platform 12, the scale in the dial 9 is set to be symmetrical, so the 0 position is located on the dial 9. In the upper middle position, when the rotating pointer 8 points to the 0 position, the cylindrical level II 14 is just horizontal, and the lowering rotating pointer 8 points to the 0 position is quick and simple, which is convenient to quickly adjust the cylindrical level II 14 level.

As shown in Figure 6, a method for rapid measurement of slope inclination includes the following steps:

Step 1. Building the ground monitoring pier of the slope body: Drill down holes at the edge of the slope body and pour concrete into the hole to form a ground monitoring pier 18 connected to the slope body;

It should be noted that the upper surface of the ground monitoring pier 18 is initially horizontal, which is convenient for measuring the inclination of the upper surface of the ground monitoring pier 18 when the slope is inclined, so as to measure the inclination of the slope;

Step 2. Install the leveling measuring device: first, install the measuring device on the ground monitoring pier 18, and fix the bracket 1; then, adjust the bubble in the cylindrical level-11 by rotating the bolt 13 to move in the descending direction until the bubble is centered, by adjusting The rotating ring 10 makes the rotating pointer 8 at the 0 position; finally, the circular level bubble 6 is centered by rotating the adjusting bolt 4;

Step 3. Record the initial azimuth angle α of the slope body: after the measuring device is leveled, record the relative position of the current compass 17 in the N direction and the compass 5, and record the current reference pointer 16 and the compass 17 in the counterclockwise direction of the N direction. angle, determine the initial azimuth angle α of the slope;

Step 4. Determine whether the slope has changed inclination: observe whether the initial azimuth angle α of the slope body and the air bubbles in the cylinder level 2 14 have shifted. If the slope changes, go to Step 5; when the initial azimuth angle α of the slope and the bubbles in the cylinder level 2 14 do not shift, it means that the slope has not changed, and continue to observe the changes of the measuring device;

In this embodiment, under the condition of no slope inclination, the upper surface of the ground monitoring pier 18 is kept horizontal, and the measuring device is fixedly installed on the ground monitoring pier 18. The rotating platform 12 is horizontal, so that the rotating platform 12 is parallel to the upper surface of the ground monitoring pier 18 in real time. When the slope is inclined, the ground monitoring pier 18 is inclined with the slope, and the ground monitoring pier 18 is inclined along with the ground monitoring pier 18. Both the azimuth and the inclination angle change. When measuring the azimuth angle of the ground monitoring pier 18, the reference pointer 16 is used as a reference to point to a certain scale on the compass 5. The compass 17 rotates freely and always points to the north-south direction, corresponding to a scale on the compass 5. The change of the relative position of the reference pointer 16 and the compass 17 and the change of the included angle are used to determine the change of the azimuth angle of the ground monitoring pier 18;

Step 5. Record the azimuth angle α' after the slope is inclined and obtain the offset azimuth of the slope: First, record the relative position of the compass 17 and the compass 5 after the slope is inclined, and simultaneously record the relative positions of the reference pointer 16 and the compass 17 after the slope is inclined. The included angle in the counterclockwise direction of the N direction determines the azimuth angle α' after the slope is inclined; then, according to the formula Δα=α-α', calculate the azimuth change Δα of the slope, and obtain the N direction angle of the slope offset compass 17 , the N direction angle of the slope body offset compass 17 is the slope body offset azimuth;

Step 6. Obtain the slope back inclination angle β: First, rotate the rotating platform 12 by rotating the bolt 13 in the plane where it is located along the level bubble in the cylindrical level-11 along the descending direction, and keep the plane where the rotating platform 12 is located and the slope body. The relative position of the plane on which the upper surface of the ground monitoring pier 18 is tilted remains unchanged until the bubbles in the two parallel cylindrical levels 11 are centered, and then the rotation of the rotating platform 12 is stopped. At this time, the bubbles in the two cylindrical levels 11 are stopped. Centered and the rotating pointer 8 is at the 0 position, the bubble of the cylinder level 2 14 is not centered; then, rotate the rotating ring 10 until the bubble in the cylinder level 2 14 is centered, and the scale on the dial 9 that the rotating pointer 8 points to is the cylinder level 2 14 turns The angle through which the second cylinder level 14 is turned is the slope back inclination angle β.

In this embodiment, the upper surface of the slope ground monitoring pier 18 constructed in step 1 is parallel to the ground; in step 6, the rotating platform 12 is rotated in the plane where the rotating platform 12 is located by rotating the bolt 13 to keep the plane where the rotating platform 12 is located and the slope. The plane on which the upper surface of the ground monitoring pier 18 after the body is inclined is always kept parallel.

When actually measuring the slope back inclination angle β, as shown in Figures 4 and 5, the change of the azimuth angle of the ground monitoring pier 18 is accompanied by the change of the inclination angle of the ground monitoring pier 18, and the inclination angle of the ground monitoring pier 18 is the upper The angle between the plane where the surface is located and the plane where the horizontal ground is located. The angle between the surface and the surface is the angle between the two lines that draw a line perpendicular to the intersection and intersect at the same point on the intersection. That is, the angle between the surface and the surface. 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. The slope is inclined, the air bubbles in the two cylindrical levels 11 on the rotating platform 12 and the air bubbles in the cylindrical level 2 14 are offset, and the rotating platform 12 is rotated by the rotating bolt 13 in the plane where it is located until it is parallel. The two cylindrical levels - 11 are level. At this time, one of the two cylindrical levels - 11 is at a high position to keep level, and the other cylindrical level - 11 of the two cylindrical levels - 11 is at a low position to keep level. The horizontal position of each cylindrical level-11 is unique. Since any straight line on the horizontal plane is in a horizontal state, the intersection line of the extension line of the rotating platform 12 and the horizontal plane is bound to be in a horizontal state. Therefore, the cylindrical level-11, which is located at a low position and remains horizontal, can be seen For the intersection line of 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 maintains the level. 9. Vertically installed on the rotating platform 12, the cylindrical level 2 14 after the level adjustment can be regarded as a straight line on the horizontal plane perpendicular to the cylindrical level 1 11 located at a low position and kept horizontal. Therefore, the angle at which the cylindrical level 2 14 is turned is ground monitoring. The inclination angle of the pier 18, the inclination angle of the ground monitoring pier 18 is the slope back inclination angle β, and the slope back azimuth angle and inclination angle obtained by the measurement can reflect the inclination of the side slope.

The above are only preferred embodiments of the present invention and do not limit the present invention. Any simple modifications, changes and equivalent structural changes made to the above embodiments according to the technical essence of the present invention still belong to the technology of the present invention. within the scope of the program.
