Description
Technical Field
The utility model relates to a geological profile thickness measurement technical field especially relates to a geological profile thickness measurement device.
Background
Geological profile measurement is a traditional means of geological survey work and is an important way for acquiring basic information such as stratum attitude, thickness, lithology and the like. In geological works such as ground matrix layer investigation, ecological geological investigation, geodesic zone investigation, etc., soil becomes an important investigation object as bedrock and its weathered objects, and it is necessary to measure the entire thickness of soil and bedrock and the thickness of each layer inside the soil and bedrock, respectively. The relative spatial positions of the stratum, the soil layer and the profile can directly influence the thickness measurement result, the real thickness of the target layer (the stratum or the soil layer) can be directly measured only when the included angle between the stratum or the soil layer and the profile is 90 degrees, and the measured data are the exposed thickness of the target layer under other conditions. Therefore, in the middle-low scale investigation work, in order to ensure the working efficiency, the exposed thickness of the target layer is approximately equal to the real thickness. Under the condition of higher precision requirement, the real thickness of the target horizon can be calculated after the inclination angle of the target horizon is measured. At present, a geological profile measuring method generally comprises two modes of contact measurement and non-contact measurement, wherein the contact measurement mainly utilizes a tower ruler and a tape to be close to a profile for measurement, and the non-contact measurement mainly utilizes a handheld laser range finder for measurement.
The step of measuring the sliding staff is as follows: (1) removing the surface soil on the section to ensure that the fresh surface is vertical to the horizontal plane so as to accurately measure the thickness; (2) manually placing the sliding staff in front of the fresh surface in a vertical horizontal plane manner; (3) and manually referring to the scale of the tower ruler, and recording the thickness of each layer. The tape measure procedure was as follows: (1) removing the surface soil on the section to ensure that the fresh surface is vertical to the horizontal plane; (2) one person stands on the top of the section, and a tape measure is put down to the bottom of the section and is fixed; (3) the thickness of each layer was recorded according to the tape scale. If the height of the section is high and the floating soil is difficult to clean, the measurement is directly carried out. The contact measurement method has the characteristics of low tool cost and easy operation, is widely applied in practical work, but has more prominent defects. Firstly, the application scene is limited, and the measurement is difficult to be carried out under the blocking condition of rivers, highways and the like because the measurement needs to be carried out close to the section; secondly, the measuring range is limited, and the distance measurement of the tower ruler and the tape ruler is difficult to meet the requirements of section measurement with higher height; the subjective error is measured again, and large errors are generated when the placement posture of the tower ruler is vertical, the reading sight line is vertical to the ruler surface and the like; finally, the safety is relatively low, and since the measuring staff is required to reach the top of the profile or stand at the bottom of the profile during the measuring work, the risk of falling from a high place or being hit by a falling stone exists.
The handheld laser range finder measures the distance by adopting a phase method, one or more laser beams are emitted to a target object during measurement, the laser beams reflected by the target object are received by the photoelectric element, the distance from a measurer to the target object is calculated by measuring the phase difference of the reflected laser beams, the distance value is further calculated as the height of a target point by the angle sensor, and the thickness of the target layer is obtained through the height difference. The measuring steps are as follows: (1) selecting a proper position to face the geological profile by a measurer within the range of laser ranging; (2) selecting a plurality of points on the boundary of the target layer on the geological profile for measurement; (3) and calculating the mean value of the plurality of measured values to obtain the thickness of the geological section target layer. The problem that the geological profile is measured by the handheld laser range finder is not limited by the range basically, the measurement does not need to reach the position near the geological profile, the flexibility of field measurement is improved, and the danger caused by falling or smashing is avoided. However, due to the difference in the body posture or the position of the measuring person during measurement, the measurement results of different target points are difficult to be guaranteed as the same measurement reference, and thus a large human error is generated. On the other hand, when measuring a non-vertical section or a non-horizontal target layer with a large inclination angle, the handheld laser range finder cannot measure spatial characteristics of a geological section and a target layer boundary, such as the gradient and the slope direction of the section, vector information of the target layer boundary and the like.

TABLE 1
Right the utility model discloses the measurement principle introduces:
the device utilizes the main and auxiliary measuring modules to obtain distance information and attitude information, and realizes initialization and measurement of different types of geological profiles through a program algorithm.
The basic principle is as follows:
as shown in fig. 8, the directions of the three axes X, Y, Z are defined by initialization of measurement, taking the case of no reference point as an example, the point where the device is located is the origin O, the coordinates of the point a to be measured are (x, y, z),
alpha is an angle which takes X as an axis and deflects from the positive direction of the Y axis to the positive direction of the Z axis; beta is an angle which takes Y as an axis and deflects from the positive direction of the Z axis to the positive direction of the X axis; gamma is the angle of deflection from Y-axis positive direction to X-axis positive direction with Z as axis, and the values of alpha, beta and gamma are all [0, pi]Then, there are:
in the formula, alpha, beta, gamma can be measured by an inertial navigation module, and d can be measured by laserMeasured by the distance module, so that the values of x, y and z can be obtained, and the spatial position of the point A, i.e. the vector, can be determined
The device initialization principle is as follows:
based on the principle, the space vector from the main and auxiliary measuring modules to the point to be measured or the reference point can be measured, but the structural design of the device is difficult to ensure that the main and auxiliary measuring modules have the same distance measuring origin, so that the parameters of the main and auxiliary measuring modules need to be calculated through device initialization so as to improve the measuring precision of the device in use.
In actual measurement, as shown in fig. 9, the distance measurement origin of the main measurement module is O, the distance measurement origin of the sub measurement module is O', the point to be measured is a, the reference point is B,
is the vector to be measured. Due to the fact that
Knowing vectors from fundamental principles
Can be measured by the main and auxiliary measuring modules respectively if
If known, a vector can be obtained
Further, the distance between the two points, the altitude, etc. can be calculated A, B.
As can be seen from the device structure, the point O '(x', y ', z') rotates with the rotation of the secondary measurement module. Taking the posture of the device during measurement initialization as an example, the device is horizontally placed, the X, Y, Z three-axis directions are as shown in fig. 10, the main measurement module faces to the positive direction of the X axis, and the auxiliary measurement module faces to the negative direction of the Z axis; the auxiliary measuring module rotates by taking a point P (x, y, z) as a circle center, the rotating radius is r,
and the included angle between the Z-axis negative direction and the Z-axis negative direction is theta, omega is the angle of the auxiliary measuring module rotating relative to the main measuring module, and omega is 0 degree during measurement initialization. Then there are:
in the formula, omega can be calculated by the attitude information of the main and auxiliary measurement modules in the use of the device. Therefore, the temperature of the molten metal is controlled,
for a function of 5 parameters of x, y, z, r and theta, by obtaining a plurality of different sets
The value of (2) is used for establishing an equation set, namely the 5 parameters can be solved, and the initialization of the device is completed.
The principle of slope measurement is as follows:
when a compass is used for measuring the slope direction of a section, after a measurer finds the direction opposite to the section through visual judgment, the measured slope direction contains a large subjective error, and the measurer cannot reach the opposite position of the section easily in some cases. When the device measures the slope, the attitude sensor in the device can acquire the absolute azimuth of a coordinate system with east (X plus) north (Y plus) day (Z plus), a measurer adjusts the auxiliary measuring module to be horizontal and faces the section (the direction is just right as much as possible), the main measuring module is kept still, and the auxiliary measuring module can be rotated to acquire the relative position information of a plurality of points on the section, as shown in fig. 11.
The three points A, B and C on the section measured by the revolute pair measuring module are theoretically on the same horizontal line, and the device initialization principle shows that the three points A, B and C are measured by the auxiliary measuring module under different rotation angles, but the distance measurement origin points of the three points are the distance measurement origin point O of the main measuring module (the main measuring module does not move during measurement); from the basic principle, vectors
Can be obtained by measurement.
Setting point D as one point on the section, collinear with three points A, B and C, and vector
The projection direction of the linear and the slope surface normal on the horizontal plane is collinear, and the vector is
The direction of (A) is the slope direction, and the vector sum formed by any two points of the three points A, B and C is also known
Perpendicular, will vector
Calculating vectors with the points O respectively
And obtaining the slope direction by averaging the calculation results. If the vector cannot be guaranteed under the limitation of measurement conditions
Parallel to the horizontal plane, then vector
The projection direction on the horizontal plane is the slope direction.
The principle of gradient measurement is as follows:
taking the case that the laser emitted by the main measurement module in the horizontal position cannot fall on the cross section as an example, as shown in fig. 12,
the two points A and B are measured points on a section plane of the main and auxiliary measuring modules after the device rotates in the y direction, the plane OAB is vertical to the horizontal plane, and beta is1＝∠AOD，β2Becoming equal to BOD; passing through point A as
Perpendicular line ofAnd is and
the extension lines intersect at a point C, E is
At the upper point, if | BD | ═ EC |, the tangent value of ═ ABE is the gradient. Then there are:
in the formula, beta1,β2Can be measured by an inertial navigation module, and the vector can be known by the basic principle
The values of | OB |, | OA | can be obtained, so that the gradient value of the cross section can be obtained by calculating tan ^ ABE.
Target layer measurement principle:
taking the measurement of a non-horizontal target layer of an inclined geological section as an example, as shown in FIG. 13, A, A 'are two target points on the upper boundary of the target layer, B, B' are two target points on the lower boundary of the target layer, and the passing point A is taken as the passing point
Perpendicular to the line of
Cross over to point C. The measurement results include the gradient (tan lambda) and the slope direction (unit vector) of the geological section
) Angle between boundary vector of target layer and horizontal plane
The distance (| AC |) between the upper and lower boundaries of the target layer is the exposure thickness.
The principle of measuring the gradient and the slope direction is the same as the above; target layer boundary vector
Can be measured by means of devices according to the basic principle
The vertical distance is h, the included angle between the boundary vector of the target layer and the horizontal plane
According to
Perpendicular to
And the collinearity of three points B, C, B' can be obtained
And obtaining the distance | AC | of the upper and lower boundaries of the target layer.
