[0002] Structural surface investigation is very important as the basic work for rock mass engineering quality evaluation. In order to solve rock mass stability problems such as mining engineering and civil engineering, on-site field investigation is often required. Among them, the structural surface occurrence data is generally measured by compass, but in an environment with magnetic field interference (such as magnetite), the accuracy of the compass is seriously disturbed, and it is difficult to achieve a good measurement effect of the compass. Usually, technicians will use a slope gauge as a substitute, but when operating a traditional slope gauge, the measurement process is cumbersome, inefficient, and poor in accuracy due to the frequent manual movement and rotation of the slope gauge. It is generally difficult to use a compass to measure structural surfaces in an environment with magnetic field interference. The operation steps of ordinary conventional slope gauges are cumbersome, inefficient, and the accuracy is also deteriorated due to the numerous steps. Therefore, it is particularly important to study a simple slope gauge that is resistant to magnetic field interference to improve measurement efficiency and increase data accuracy.

DETAILED DESCRIPTION

[0016] Example 1

[0017] like Figures 1 to 4As shown, a slope gauge for use in a magnetic field interference environment comprises: a main structure 1, the main structure 1 is a block structure, used to carry various components; and a through hole 2, the through hole 2 is arranged on the main structure 1, and is used to install a structural surface direction value measurement mechanism; a structural surface inclination dial 3, the structural surface inclination dial 3 (0~360°) is arranged around the surface of the main structure 1 outside the through hole 2, and is used to measure the structural surface inclination when the leveler 7 is leveled; a slide groove 24 is arranged inside the through hole 2 of the main structure 1 ( Used as a track); the structural surface direction value measuring mechanism includes a level 7, which is movably arranged in the perforation 2 of the main structure 1, and a ring 21 is arranged on the periphery of the level 7. A pair of support rods 22 are symmetrically arranged on the outer side of the ring 21, and sliders 23 are respectively arranged at the ends of the support rods 22, and the sliders 23 are slidably connected with the slide groove 24; and a direction and inclination dial 5 (0~360°), the direction and inclination dial 5 is arranged around the surface of the ring 21; a pointer 6, the pointer 6 is rotatably arranged on the middle upper surface of the level 7. The main structure 1 is composed of two symmetrical pieces. A vacancy is arranged on the main structure 1, which is used as a handle 4. There is a pointer, and the level 7 is fixedly connected to the ring 21.

[0018] like Figure 6 As shown, the slider 23 is in the shape of a rectangular body with rounded corners, the slide groove 24 matches the shape of the slider 23, and the support rod 22 is rotatably connected to the ring 21.

[0019] Working process: In the specific implementation, the technician holds the handle 2, presses the long side of the slope gauge against the structural surface, and makes the slope gauge plane perpendicular to the earth (that is, the slope gauge plane is vertical to the earth), and then rotates the level 7. When the bubble is in the horizontal center position, read the degree on the structural surface inclination dial 3 pointed by the pointer 6, and record the data as the structural surface inclination. At this time, let the level 7, the pointer 6, the ring 21 and the direction and inclination dial 5 rotate around the support rod 22 (the slider 23 is in the shape of a rounded rectangle and can only rotate in the slide groove 24, but the support rod 22 is rotatably connected to the ring 21, and protrusions are provided at both ends of the support rod 22, and the corresponding ring 21 is provided with a groove. The protrusion of the support rod 22 is movably connected with the groove, and can be integrally formed through 3D printing technology; the slider 23 in the shape of a rounded rectangle is relatively stable when rotating in the ring and is not easy to change), so that the ring 21 and the direction and inclination scale The disk 5 is level with the earth (i.e. parallel to the horizontal plane), and the bubble 8 in the level 7 is kept in the center position. At this time, the degree a of the inclination dial 5 pointed by the pointer 6 is recorded (generally, the pointer 6 and the level 7 are set vertically at this time), and then the pointer 6 is rotated to make the pointer 6 parallel to the reference object (such as a tunnel with a known direction underground, the tunnel direction α is known), and the degree b of the dial 5 at this moment is recorded. The difference between b and a is the degree difference c between the direction of the structural surface and the direction of the reference object. The direction value of the structural surface can be calculated based on the direction of the reference object.

[0020] like Fig. 9 , assuming that the structural plane strike value is β;

[0021] c=ba, which is the difference between the first measured angle and the second measured angle;

[0022] At this time, according to the known lane direction α;

[0023] The structural surface strike value β = α-c or 360° + (α-c);

[0024] (1) That is, when c≤α, β=α-c; for example, α=30°, c=20°, β=α-c=10°;

[0025] (2) That is, when c>α, β=360°+(α-c); for example, α=30°, c=40°, β=360°+(α-c)=350°.

[0026] Example 2

[0027] The difference between Example 1 and Example 1 is that:

[0028] like Figure 5 The slider 23 is spherical, the slide groove 24 matches the shape of the slider 23 , and the support rod 22 is fixedly connected to the ring 21 .

[0029] Working process: In the specific implementation, the technician holds the handle 2, presses the long side of the slope gauge against the structural surface, and makes the plane of the slope gauge perpendicular to the earth (that is, the plane of the slope gauge is plumb with the earth), and then rotates the level 7. When the bubble is in the horizontal center position, read the degree on the structural surface inclination dial 3 pointed by the pointer 6, and record the data as the structural surface inclination. At this time, let the level 7, the pointer 6, the ring 21 and the direction and inclination dial 5 rotate around the slider 23 (the slider 23 is spherical, and the support rod 22 is fixedly connected to the ring 21, so that the slider 23 can rotate in the slide groove 24, and can also rotate in the slide groove 24), so that the ring 21 and the direction and inclination dial 5 are level with the earth (that is, parallel to the horizontal plane), and keep the bubble 8 in the level 7 in the center position. At this time, record the degree a of the direction and inclination dial 5 pointed by the pointer 6 (generally, the pointer 6 and the level 7 are set vertically at this time), and then rotate the pointer 6 to make the pointer 6 parallel to the reference object (such as a tunnel with a known direction underground, the tunnel direction α is known), record the degree b of the dial 5 at this moment, the difference between b and a is the degree difference c between the direction of the structural surface and the direction of the reference object, and the direction value of the structural surface can be calculated according to the direction of the reference object.

[0030] Assume that the strike value of the structural surface is β;

[0031] c=ba, which is the difference between the first measured angle and the second measured angle;

[0032] At this time, according to the known lane direction α;

[0033] The structural surface strike value β = α-c or 360° + (α-c);

[0034] (1) That is, when c≤α, β=α-c; for example, α=30°, c=20°, β=α-c=10°;

[0035] (2) That is, when c>α, β=360°+(α-c); for example, α=30°, c=40°, β=360°+(α-c)=350°.

[0036] Example 3

[0037] A slope gauge for use in a magnetic field interference environment comprises: a main structure 1, wherein the main structure 1 is a block structure for carrying various components; and

[0038] A perforation 2 is provided on the main structure 1 for installing a structural surface direction value measuring mechanism; a structural surface inclination dial 3 (0-360°), which is arranged around the surface of the main structure 1 outside the perforation 2, and is used to measure the structural surface inclination when the leveler 7 is leveled; a slide 24 is provided inside the perforation 2 of the main structure 1; the structural surface direction value measuring mechanism includes a leveler 7, which is movably arranged in the perforation 2 of the main structure 1, and a ring 21 is provided outside the leveler 7, and a pair of support rods 22 are symmetrically arranged outside the ring 21, and sliders 23 are respectively provided at the ends of the support rods 22, and the sliders 23 are slidably connected with the slide 24; and a direction and inclination dial 5 (0-360°), which is arranged around the surface of the ring 21; a pointer 6, which is rotatably arranged on the upper surface of the middle part of the leveler 7.

The slider 23 is spherical, the shape of the slide 24 matches that of the slider 23, and the support rod 22 is fixedly connected to the ring 21.

[0040] Working process: In the specific implementation, the technician holds the handle 2, presses the long side of the slope gauge against the structural surface, and makes the plane of the slope gauge perpendicular to the earth (that is, the plane of the slope gauge is plumb with the earth), and then rotates the level 7. When the bubble is in the horizontal center position, read the degree on the structural surface inclination dial 3 pointed by the pointer 6, and record the data as the structural surface inclination. At this time, let the level 7, the pointer 6, the ring 21 and the direction and inclination dial 5 rotate around the slider 23 (the slider 23 is spherical, and the support rod 22 is fixedly connected to the ring 21, so that the slider 23 can rotate in the slide groove 24, and can also rotate in the slide groove 24), so that the ring 21 and the direction and inclination dial 5 are level with the earth (that is, parallel to the horizontal plane), and at the same time keep the bubble 8 in the level 7 in the center position, at this time record the degree a of the direction and inclination dial 5 pointed by the pointer (two pointers overlap) (initial state, the two pointers overlap and are vertically set to the level 7), then rotate one of the pointers to make it parallel to the reference object (such as a tunnel with a known direction underground, the tunnel direction α is known), record the degree b of the dial 5 at this moment, the difference between b and a is the degree difference c between the direction of the structural surface and the direction of the reference object, and the direction value of the structural surface can be calculated according to the direction of the reference object.

[0041] like Fig. 9 , assuming that the structural plane strike value is β;

[0042] c=ba, which is the difference between the first measured angle and the second measured angle;

[0043] At this time, according to the known lane direction α;

[0044] The structural surface strike value β = α-c or 360° + (α-c);

[0045] (1) That is, when c≤α, β=α-c; for example, α=30°, c=20°, β=α-c=10°;

[0046] (2) That is, when c>α, β=360°+(α-c); for example, α=30°, c=40°, β=360°+(α-c)=350°.

[0047] Example 4

[0048] The difference between Example 3 and Example 3 is that:

[0049] The slider 23 is in the shape of a rectangular body with rounded corners. The slide groove 24 matches the shape of the slider 23 . The support rod 22 is rotatably connected to the ring 21 .

[0050] Working process: In the specific implementation, the technician holds the handle 2, presses the long side of the slope gauge against the structural surface, and makes the slope gauge plane perpendicular to the earth (that is, the slope gauge plane is vertical to the earth), and then rotates the level 7. When the bubble is in the horizontal center position, read the degree on the structural surface inclination dial 3 pointed by the pointer 6, and record the data as the structural surface inclination. At this time, let the level 7, the pointer 6, the ring 21, and the direction and inclination dial 5 rotate around the support rod 22 (the slider 23 is in the shape of a rounded rectangle and can only rotate in the slide groove 24, but the support rod 22 is rotatably connected to the ring 21, and the two ends of the support rod 22 are provided with protrusions, and the corresponding ring 21 is provided with grooves. The protrusions of the support rod 22 are movably connected with the grooves, and can be integrally formed through 3D printing technology) to make the ring 21 and the direction and inclination dial 5 level with the earth (that is, parallel to the horizontal plane), while keeping the water level 7, the pointer 6, the ring 21, and the direction and inclination dial 5 level with the earth (that is, parallel to the horizontal plane). The bubble 8 in the leveler 7 is at the center position. At this time, record the degree a of the inclination dial 5 pointed by the pointer (the two pointers overlap) (in the initial state, the two pointers overlap and are vertically set to the leveler 7). Then rotate one of the pointers to make it parallel to the reference object (such as a tunnel with a known direction underground, the tunnel direction α is known), and record the degree b of the dial 5 at this moment. The difference between b and a is the degree difference c between the direction of the structural surface and the direction of the reference object. The direction value of the structural surface can be calculated based on the direction of the reference object.
