Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
In conjunction with shown in Fig. 1 to Fig. 3, the ground settlement measuring device of the utility model is schematically showed, including swash
The bottom end of light device 1, baseline rod 2 and measurement assembly 3, baseline rod 2 is vertically inserted into earth's surface 4 and is connected to basement rock 5, and laser 1 is set
In earth's surface 4 to be measured；Baseline rod 2 be equipped with the first graduated scale 21, measurement assembly 3 by slide assemblies 22 be actively connected in
Baseline rod 2 enables measurement assembly 3 to be slided on the length direction of baseline rod 2, and measurement assembly 3 is recessed including being oppositely arranged
Mirror 31 and the second graduated scale 32, the height of concavees lens 31 in the vertical direction are 8~10mm, and settling amount, which is less than 4~5mm, then to be made
With the second graduated scale 32 read, when settling amount be more than above range, should use the first graduated scale 21 read.Laser 1 projects
Laser can be radiated at simultaneously on the first graduated scale 21 and the second graduated scale 32, wherein concavees lens 31 are located at laser 1 and
Between two graduated scales 32, the focal lengths of concavees lens 31 is 7~9mm, and the distance of the second graduated scale 32 and concavees lens 31 is concavees lens 31
0.9~1.2 times of focal length, the scattering that the laser of laser 1 occurs after the refraction of concavees lens 31 at this time are still within this reality
Apply the acceptable accuracy rating of example, the first graduated scale 21, the second graduated scale 32 each parallel to baseline rod 2 length direction cloth
It sets.Preferably, laser 1 is a wordline laser device 1, and the line width for the laser that a wordline laser device 1 projects is 0.2~0.3mm, is swashed
The line width that light is radiated at after the refraction of concavees lens 31 on second graduated scale 32 is no more than 0.9mm, and user reads laser irradiation and exists
After full-scale reading and least count on second graduated scale 32, the two average value is taken, you can reach the survey constructed in the present embodiment
Accuracy of measurement requirement；Meanwhile a wordline laser device 1 can make laser while be radiated at the first graduated scale 21 and the second graduated scale 32,
And the laser line segment that laser can also be kept to be on two graduated scales is in same level.
In conjunction with shown in Figure 4 and 5, slide assemblies 22 include sliding rail 22a and are actively connected in the sliding part of sliding rail 22a
22b, sliding part 22b are fixedly connected on measurement assembly 3, and sliding rail 22a is located at the top of the baseline rod 2, and sliding rail 22a is along benchmark

32 radius of curvature is 13~21mm, and the average value of the full-scale reading of calculated second graduated scale 32 and least count is most at this time
To approach true measurement；The laser beam and nonideal two-dimentional ray projected due to laser 1, laser beam is actually
By " light beam " formed without several two-dimentional rays, therefore the light beam necessarily has certain width, if the second graduated scale 32
For tabular, it is X that the laser beam of the top and the spacing between the lowermost laser beam are located in laser beam, is made
For comparison, the second graduated scale 32 is curved, and the laser beam of the top is located in laser beam and is located at the lowermost laser
Spacing between ray is Y, then X can be more than Y；Therefore, more accurate in order to read, the second graduated scale 32 answers shape in curved surface.
Conversely, because refraction of the laser without concavees lens 31 being radiated on the first graduated scale 21, the first graduated scale 21 is without in curved surface
Shape.

Step S2, it is vertically inserted into baseline rod 2 on the ground of the main body length direction side of Metro section, and makes base
The bottom end of quasi- bar 2 is connected on basement rock 5；
Step S3, laser 1 is set up in settling amount measuring point, by 1 alignment fiducials bar 2 of laser, and laser 1 is kept to project
Laser be parallel to horizontal plane；
Step S4, the position of sliding adjustment measurement assembly 3 makes the main shaft 31b of the laser and concavees lens 31 of the injection of laser 1
It overlaps；
Step S5, when the numerical value of settling amount is more than the radius of concavees lens 31, the reading of the first graduated scale 21 of reading；Work as sedimentation
The numerical value of amount is less than the radius of concavees lens 31, the reading of the second graduated scale 32 is read, by the reading or second of the first graduated scale 21
The reading of graduated scale 32 is denoted as settling amount reading.
Step S6, it is read to draw sedimentation change curve, sedimentation pace of change curve graph and settle according to settling amount and be changed
Acceleration plots.
In addition, step S5 further includes：
The width of the main body of Metro section is denoted as A；
With the settling amount measuring point for being more than 4A at a distance from the main body of Metro section, 2 settling amount readings are recorded weekly；
