Specific implementation mode
With reference to the accompanying drawings and examples, the specific implementation mode of the present invention is described in further detail.Implement below
Example is not limited to the scope of the present invention for illustrating the present invention.
In conjunction with shown in Fig. 1 to Fig. 3, the supporting vault sinking monitoring device of the present invention, including hanging rod are schematically showed
1, laser 2, baseline rod 3 and measurement assembly 4, laser 2 are set to the bottom end of hanging rod 1, and the side wall of baseline rod 3 is equipped with calibration and carves
Ruler 31 is spent, measurement assembly 4 is actively connected by slide assemblies 32 in baseline rod 3, enables measurement assembly 4 in baseline rod
It is slided on 3 length direction；Measurement assembly 4 includes base pointer 41 and the concavees lens 42 being oppositely arranged and sedimentation graduated scale
43, the height of concavees lens 42 in the vertical direction is 8~10mm, i.e., the settling amount measuring range of the device is 8~10mm, is met
The focal length of the measurement request constructed in the present embodiment, concavees lens is 4~6mm, and settles the distance of graduated scale 43 and concavees lens 42
It it is 0.9~1.2 times of 42 focal length of concavees lens, the scattering that the laser of laser 2 occurs after the refraction of concavees lens 42 at this time is still
So it is in the acceptable accuracy rating of the present embodiment, the movable end of base pointer 41 is against calibrated scale ruler 31；Actually make
In, first in 5 supporting vault of tunnel setting hook 51, then the top carry of hanging rod 1 erects baseline rod 3 on hook 51
It is directly set on the ground in tunnel 5, can start to measure after adjusting position of the measurement assembly 4 on baseline rod 3.Preferably, swash
Light device 2 is a wordline laser device 2, and the line width for the laser that a wordline laser device 2 projects is 0.2~0.3mm, and laser is through concavees lens 42
The line width being radiated at after refraction on sedimentation graduated scale 43 is no more than 0.8mm, and user reads laser irradiation in sedimentation graduated scale 43
On full-scale reading and least count after, both take average value, you can reach the measurement accuracy requirement constructed in the present embodiment, one
The laser that word laser 2 projects is in a line segment on sedimentation graduated scale 43, when convenient for users to reading, one section of laser after all
Than one laser point of line segment is more intuitive, second is that may determine that whether baseline rod 3 is vertically to water as requested according to laser line segment
Plane Installation avoids because of survey measurements error caused by the erection error of baseline rod 3.
In conjunction with shown in Fig. 4 and Fig. 5, slide assemblies 32 include sliding rail 32a and are actively connected in the sliding of sliding rail 32a
Part 32b, sliding part 32b are fixedly connected on measurement assembly 4, and sliding rail 32a is located on baseline rod 3, and sliding rail 32a is along baseline rod 3
Length direction is arranged；Moreover, sliding part 32b is equipped with lock-screw 32c, position of the measurement assembly 4 on baseline rod 3 is adjusted
After, lock-screw 32c is tightened to lock measurement assembly 4 and baseline rod 3.Certainly, if only with manual adjustment measurement assembly 4
Position on baseline rod 3, which is inaccurate, final survey measurements, will generate certain error, for this purpose, in sliding part 32b
The output shaft of upper setting driving device (not shown), driving device is equipped with gear, in the fixed rack in the side of sliding rail 32a, tooth
Wheel and rack are meshed, and drive measurement assembly 4 to be slided on baseline rod 3 by driving device, driving device further reduces
The left-hand seat difficulty of the device.
In the present embodiment, the minute surface of concavees lens 42 is the C-shaped groove 42a in cross section, and the length direction of groove 42a
Both ends run through the both sides of concavees lens 42 respectively, the concavees lens 42 of the structure can allow the laser line segment of a wordline laser device 2
Display is in a straight line segment on sedimentation graduated scale 43, as a comparison, if concavees lens 42 are traditional round concavees lens 42, one
For the laser line segment of word line laser device 2 through the refraction of round concavees lens 42, what laser was presented on sedimentation graduated scale 43 is not one
Straight line segment is unfavorable for user's pin-point reading.Corresponding, sedimentation graduated scale 43 is curved, and concave surface is equipped with graduation mark,
Laser reflects the concave surface for being projeced into sedimentation graduated scale 43 by concavees lens 42, and the radius of curvature of sedimentation graduated scale 43 is 7~14mm,
The closest true measurement of average value of the full-scale reading and least count of calculated sedimentation graduated scale 43 at this time；Due to swashing
The laser beam and nonideal two-dimentional ray that light device 2 projects, laser beam are actually by being formed without several two-dimentional rays
" light beam ", therefore the light beam necessarily has certain width, if sedimentation graduated scale 43 is tabular, is located in laser beam
The laser beam of the top and the spacing between the lowermost laser beam are A, and as a comparison, sedimentation graduated scale 43 is song
Planar, it is B that the laser beam of the top and spacing between the lowermost laser beam are located in laser beam, then A
B can be more than；Therefore, more accurate in order to read, sedimentation graduated scale 43 answers shape in curved surface.
In order to solve identical technical problem, the present invention also provides a kind of supporting vault sinking monitoring methods, including under
Row step：
Step S1, it by 1 carry of hanging rod on the hook 51 of 5 supporting vault of tunnel, and sets up on 5 ground of tunnel and sets vertically
The baseline rod 3 set；
Step S2, leveling is carried out to laser 2, the laser that laser 2 emits is made to be parallel to horizontal plane, and laser alignment base
Quasi- bar 3；
Step S3, slidable adjustment measurement assembly 4, the laser weight for making the main shaft 42b of concavees lens 42 and the laser 2 emit
It closes, and position of the measurement assembly 4 on baseline rod 3 at this time is denoted as benchmark position；
Step S4, suitable measurement period is chosen, step S1 and S2 are repeated, slidable adjustment measurement assembly 4 to benchmark position is read
Sedimentation graduated scale 43 and laser is taken to coincide the reading at place.
Wherein, step S4 further includes：
It reads sedimentation graduated scale 43 and laser coincides the full-scale reading and least count at place, and calculate full-scale reading and most
The average value of small reading is denoted as average reading, and discussion laser beam above is not an ideal two-dimentional ray, therefore in reality
During reading, the average value of full-scale reading and least count is taken, can obtain more accurately reading.
