Embodiment
Hereinafter in connection with accompanying drawing embodiments of the invention are elaborated.Need to prove that in the situation of not conflicting, the embodiment among the application and the feature among the embodiment be combination in any mutually.
For the slope of even sandrock, measure along the slide displacement of ramped surfaces to cause the slope angle unstability be responsive effectively, ramped surfaces measure the landslide rotation tilt then for the monitoring slope above progressively the trend of unstability be effective way.Such as retrogressive landslide, the deformation failure of toe is significantly with respect to the deformation failure of top, slope, and the mode of the deformation failure of slope trailing edge employing displacement monitoring is unconspicuous, and adopting obliquity sensor measurement top layer rotation to tilt is very effective way.The landslide in the process of carrying out not only the slope know from experience to produce slippage up and down and frustrate, the angle about also having in the horizontal direction changes (change of the glide direction that namely comes down).
As described in Figure 1, the device of the measurement of embodiment of the invention landslide surface tilt and main sliding direction of landslide comprises: obliquity sensor 1, and angular transducer 2 and adaptive workpiece, described adaptive workpiece comprises cylinder 3; Described angular transducer 2 is cylindrical, and eccentric plumbous pendulum 22 is installed on its main shaft 21, and described angular transducer 2 is installed in the top in the described cylinder, changes for the angle of measuring main sliding direction of landslide; Described obliquity sensor 1 is cylindrical, is installed in the bottom in the described cylinder, is used for measuring the angle variation of landslide surface tilt.
In addition, described adaptive workpiece also comprises taper entity steel part 4, and described taper entity steel part 4 is installed in the bottom of described cylinder 3.
Obliquity sensor 1 adopts unidirectional measurement, namely only the rotation of X-axis is tilted to measure, measurement range is-30 ° ~+30 °, service precision is per mille, obliquity sensor is made into cylindrical and at the measurement axis of right cylinder mark sensor, and because its inside is provided with eccentric plumbous pendulum 11, so the center of gravity spinfunction is arranged, namely the glide direction with tested gliding mass is consistent all the time for the vergence direction of sensor measurement.
Adaptive workpiece main body is pipe 3, cylinder comprises that top divides cylinder 31, bottom to divide cylinder 32, top and the bottom web member 33 and top cover labyrinth 34, wherein the described top of top and the bottom web member 33 connections divides cylinder 31 and bottom to divide cylinder 32, and top cover labyrinth 34 is installed in top and divides on the cylinder 31.Be provided with vertical level pearl 35 at top cover labyrinth 34, be used for checking when mounted and install whether vertically.
Columned obliquity sensor 1 is fixed on pipe 3 bottoms, after obliquity sensor 1 is fixedly finished, installs taper entity steel part 4 additional in pipe 3 bottoms.Top divides cylinder 31 to be used for setting angle sensor 2, angular transducer 2 is before installation, at angular transducer main shaft 21 plumbous pendulum 22 is installed, because angular transducer is non-contacting sensor, so the friction force that 21 rotations of sensor main shaft are subject to is almost nil, can put the very accurate glide direction of measuring of 22 action of gravitations by lead when glide direction changes.Divide cylinder 31 and bottom to divide cylinder 32 by top and the bottom web member 33 and top cover labyrinth 34 sealings on top behind the installation angular transducer 2, the data line 5 of angular transducer 2 and obliquity sensor 1 is drawn from the middle part of pipe 3 by a single data bus, after drawing data line 5 data line ports is sealed, guarantee that the encapsulation of whole measurement mechanism reaches IP68.
