Detailed Description
The following examples are further illustrative and supplementary of the present invention and are not intended to limit the invention in any way.
The following describes a tunnel excavation lofting point determining method, a system, electronic equipment and a medium according to an embodiment of the invention with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a method for determining a lofting point of tunnel excavation, including:
s1, acquiring a first three-dimensional coordinate and a north setting direction of a measuring robot when the measuring robot is erected at a preset distance in front of a tunnel face.
The face refers to a working face excavated in the tunneling direction, namely a rock face which is right opposite to the working personnel along a line.
The north setting direction refers to the north setting direction when the measuring robot is erected at a preset distance in front of the palm face.
In the embodiment of the invention, the preset distance is 5-20 m.
The first three-dimensional coordinate and the north setting direction are determined by a rear intersection mode, wherein the rear intersection mode is that a measuring robot is erected at any position, after an instrument is leveled, the horizontal direction, the horizontal distance and the height difference of at least two known points are observed, and the three-dimensional coordinate of a station (namely the position where the measuring robot is) and the north setting direction are calculated by intersection.
S2, determining the mileage of the tunnel face through line back calculation according to the first three-dimensional coordinates and the coordinates of any point on the tunnel face measured by the measuring robot in the prism-free measurement mode.
And S3, determining a second three-dimensional coordinate of each point to be lofted on the excavation outline under the face mileage through line calculation according to the face mileage, the preset horizontal offset distance and the preset vertical offset distance.
The preset horizontal offset (predefined by software according to a design drawing) refers to the horizontal distance between the point to be lofted and the design flat curve;
the preset vertical offset (predefined by software according to the design drawing) refers to the vertical distance from the point to be lofted to the design flat curve.
S4, for each point to be lofted, determining the pointing position of the measuring robot, which points to the corresponding direction of the point to be lofted, according to the first three-dimensional coordinate, the second three-dimensional coordinate, the north setting direction, the back calculation horizontal direction value and the back calculation vertical direction value, and determining the actual three-dimensional coordinate of the pointing position.
The back calculation of the horizontal direction value refers to the direction value of a horizontal scale which should be turned to if the telescope axis of the measuring robot points to the point to be lofted under the condition of the coordinates of the current measuring robot and the coordinates of the point to be lofted; the coordinate azimuth angle of the connecting line of the point to be lofted and the measuring robot is obtained through coordinate back calculation according to the plane coordinate of the current measuring robot and the plane coordinate of the point to be lofted, and the current north direction value (if the current north direction value is a negative value, the result is 360 degrees to become a positive value) is subtracted through the coordinate azimuth angle, so that the required back calculation horizontal direction value is obtained.
The back calculation of the vertical direction value refers to the vertical scale direction value which should be turned to if the telescope axis of the measuring robot points to the point to be lofted under the condition of the coordinates of the current measuring robot and the coordinates to be lofted; according to the three-dimensional coordinate of the current measuring robot and the three-dimensional coordinate of the point to be lofted, the height difference and the horizontal distance of the current measuring robot and the point to be lofted can be calculated, then according to a trigonometric function, the vertical angle (the included angle between the target direction and the horizontal direction is called vertical angle, the vertical angle value range is-90 degrees to 90 degrees, the target direction is an elevation angle above the horizontal direction, the sign is positive, the target direction is a depression angle below the horizontal direction, the sign is negative), the zenith distance=90 degrees to vertical angle, and the zenith distance is the required back calculation vertical direction value.
And S5, for each point to be lofted, determining the super-underexcavation value according to the actual three-dimensional coordinates and the face mileage.
The overexcavation value refers to the distance between an actual measurement point and a reference line based on a designed excavation contour line, wherein the actual measurement point is located outside the reference line and is called overexcavation, and the actual measurement point is located inside the reference line and is called underexcavation.
And S6, for each point to be lofted, if the over-and-under excavation value meets the preset condition, taking the pointing position when the over-and-under excavation value meets the preset condition as a target lofting point, if the over-and-under excavation value does not meet the preset condition, updating the actual three-dimensional coordinates to obtain updated three-dimensional coordinates, performing line inversion on the updated three-dimensional coordinates to calculate the actual mileage of the point to be lofted, updating the face mileage with the actual mileage, and repeatedly executing S3-S5 until the over-and-under excavation value meets the preset condition.
The preset condition in this example is whether the super undercut value meets the limit difference (limit error).
In the event example, a measuring robot is erected at a preset distance in front of a tunnel face of a tunnel, a first three-dimensional coordinate and a north direction of a station can be obtained, then the tunnel face mileage is automatically obtained through the first three-dimensional coordinate and the coordinate of any point on the tunnel face measured by the measuring robot in a prism-free measuring mode, a second three-dimensional coordinate of each point to be lofted on an excavation outline can be obtained under the tunnel face mileage, at this time, the pointing laser of the measuring robot can be pointed to all lofting points to determine the actual three-dimensional coordinates of each pointing position and the pointing position, the super-undermining value of each point to be lofted can be obtained according to the actual three-dimensional coordinates and the tunnel face mileage, at this time, the actual three-dimensional coordinates can be iteratively updated by repeatedly judging the super-undermining value to calculate the actual mileage of the point to be lofted through updating the three-dimensional coordinates, finally, the pointing position of the super-undermining value meeting the preset condition is used as a target lofting point, the automatic point to be improved, the whole method is completed by manually, the problem of the existing manual adjustment is solved, and the problem of the existing manual adjustment is solved.
Optionally, for each point to be lofted, if the super-underexcavation value does not meet the preset condition, updating the actual three-dimensional coordinates to obtain updated three-dimensional coordinates, performing line inversion on the updated three-dimensional coordinates to calculate the actual mileage of the point to be lofted, updating the face mileage with the actual mileage, and repeating S3-S5, including: if the super-undermining value does not meet the preset condition, determining an actual mileage through line back calculation according to the actual three-dimensional coordinates, determining an updated three-dimensional coordinate of the pointing position through the actual mileage, taking the updated three-dimensional coordinate as a new second three-dimensional coordinate, taking the actual mileage as a new face mileage, and repeatedly executing S3-S5 until the super-undermining value meets the preset condition.
The target lofting point is determined according to the face mileage, but because the face is uneven, the super-undermining value does not accord with the limit difference, so that the target lofting point is inaccurate, and therefore, the actual mileage and the second three-dimensional coordinates are required to be updated continuously in an iterative updating mode, and the aiming direction of the measuring robot is adjusted, so that the super-undermining value accords with the limit difference, and the accuracy of the target lofting point is improved.
Optionally, determining the updated three-dimensional coordinates of the pointing position by the actual mileage includes: and determining the updated three-dimensional coordinates of the pointing position according to the actual mileage, the preset horizontal offset distance and the preset vertical offset distance.
And taking the preset horizontal offset and the preset vertical offset into consideration in updating the actual three-dimensional coordinates, so that the updated three-dimensional coordinates obtained by final updating are more accurate.
Optionally, for each point to be lofted, determining the super-underexcavation value according to the actual three-dimensional coordinates and the face mileage includes: determining a third three-dimensional coordinate and a normal direction of a line point corresponding to the point to be lofted through line calculation according to the tunnel face mileage and tunnel line parameters; determining a space plane equation perpendicular to a design line at a point to be lofted according to the third three-dimensional coordinate and the normal direction; according to the space plane equation, projecting the actual three-dimensional coordinates into a projection space to determine two-dimensional coordinates corresponding to the actual three-dimensional coordinates; determining a tunnel design profile corresponding to the tunnel face mileage according to the tunnel face mileage and the section distribution table; and taking the vertical distance from the two-dimensional coordinates to the tunnel design profile as the super-underexcavation value of the point to be lofted.
In this embodiment, if the overexcavation value is a negative number, the target laying-out point is located in the excavation outline, that is, underexcavation, and if the overexcavation value is a positive number, the target laying-out point is located outside the excavation outline, that is, overexcavation.
Optionally, for each point to be lofted, the method further includes: if the number of times of repeatedly executing S5 exceeds the preset number of times, determining whether the indication laser of the measuring robot is on the face, if not, judging that the determination of the target to-be-lofted point fails, and if so, determining the horizontal distance between the pointing position and the excavation design section; and taking the pointing position as a starting point, and translating the position at the horizontal distance to the excavation direction to serve as a new target to-be-lofted point.
Because the face is rugged, even if the face mileage and the actual three-dimensional coordinates are continuously updated in an iterative way, the super-undermining value still cannot be in line with the limit difference, which indicates that the indicating laser of the current measuring robot is seriously deviated from the target lofting point, and the determination of the target lofting point cannot be realized.
The following describes the scheme of the present invention in detail by using a specific example, as shown in fig. 2, the method for determining the lofting point of tunnel excavation includes the following steps:

And S10, if the over-and-under excavation value accords with the limit difference, marking an indication laser (pointing position) of the face by using paint spraying as a target lofting point.
S11, if the super-undermining value does not accord with the limit difference, judging whether the iteration update times of the super-undermining value exceeds a preset iteration value (preset times);

And S13, if the iteration update times of the super-underexcavated value exceeds a preset iteration value, judging whether the measuring robot indicates that the laser is on the face, and if so, calculating the horizontal distance H2 of the excavation design section (the horizontal distance between the pointing position and the excavation design section).
S14, taking the face indication laser as a reference (pointing position is taken as a starting point), and translating the position at the horizontal distance along the excavation direction to be used as a mark by paint, and taking the position as a new target to-be-lofted point.
And S15, if the measuring robot is judged to indicate that the laser is not on the face, judging that the determination of the target to-be-lofted point fails.
