Background technology
At present, known Crack Monitoring device is primarily aimed at concrete, tunnel-liner, engineering geologic fissure, tunnel-liner, distress in concrete are because seam is wide less, its corresponding monitoring device physical dimension and range are all less, and the ground fissure width can reach tens centimetres, so these devices can not satisfy the ground fissure deformation monitoring requirement.Existing engineering geologic fissure monitoring device be Inst of Geology and Geophysics, Chinese Academy of Sciences " instrument for measuring 3 D deformation of engineering geologic fissure " (CN101008565A) with " portable engineering geologic fissure measurement mechanism " (CN1546808A), the former feature is that measurement of bearing instrument, drift indicator and pattern displacement measuring instrument are combined, measure flaw level tension, the horizontal changing of the relative positions and vertical changing of the relative positions deformation values, but exact instrument such as grating displacement sensor are fit to the measurement in common engineering geology crack, quick, the easy field monitoring work in crack inappositely.The latter is simple in structure, is fit to long-term field monitoring, but is subjected to the drafting board length restriction, and range is less, can not satisfy the large-deformation measuring requirement.Ground fissure is one of 6 big geologic hazards, and emerging ground fissure being carried out simple and easy, fast monitored in the open air is one of emphasis means of villages and small towns hazards control.Be difficult to adapt to quick field monitoring or needs by the deficiency of special surveying instrument for solving existing engineering geologic fissure monitoring instrument, the invention provides a kind of self-advancing slide rail pendulous ground fissure deformation monitoring device.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, easy for installation, cheap, can reclaim and repeatedly recycling the self-advancing slide rail pendulous ground fissure deformation monitoring device that requires of the long-term open-air simple and easy monitoring in crack contentedly.
The self-advancing slide rail pendulous ground fissure deformation monitoring device that the present invention proposes, form by self-advancing type soil anchor 1, first support 2, second support 10, angle scale 3, lining rope 4, first pulley 5, second pulley 11, pulley fixed bar 6, slide rail type suspending hammer 7, band scale slide rail case 8 and geometrical clamp 9, wherein: self-advancing type soil anchor 1 is a fixed pedestal, advances formula soil anchor 1 in vain and screws in the stratum, ground fissure both sides; First support 2 and second support 10 are installed in respectively on the self-advancing type soil anchor 1, and first support 2 and second support 10 are all collapsible; Angle scale 3 is installed on second support, 10 tops, and first pulley 5 is installed in first support, 2 tops, and second pulley 10 is installed on first support 2 by pulley fixed bar 6; Slide rail type suspending hammer 7 is positioned in the band scale slide rail case 8, and slide rail type suspending hammer 7 upper ends connect lining rope 4, and lining rope 4 other ends are fixed on first support 10 by second pulley 11, first pulley 5 successively; Band scale slide rail case 8 usefulness geometrical clamps 9 are fixed in first support, 2 one sides; During use, when local flaw level expansion or compression, first support 2 and second support 10 produce displacement with ground fissure and arranged on left and right sides stratum, lining rope 4 stretches or shrinks, drive slide rail type suspending hammer 7 and rise or descend, can read ground fissure horizontal extension or compression displacement amount by band scale slide rail case 8; When ground fissure vertically developed, first support 2 and second support 10 produced vertically opposite displacement, and corresponding increase of lining rope 4 angles or minimizing on the angle scale 3 go out the angle changing value by index dial 3 is readable, calculate the perpendicular displacement amount.
Among the present invention, the minimum scale of described angle scale 3 is 1/60 degree.
Among the present invention, according to the difference of measured journey, lining rope 4 can be changed as required.
The invention has the beneficial effects as follows:
(1) utilize self-advancing type soil anchor to realize the quick of monitoring device from advancing to install and can reclaiming.
(2) utilize the slide rail suspending hammer to realize the tension of lining rope and reduce the influence of environment take-up device.
(3) lining rope can satisfy the needs of different ranges, and length can make things convenient for adjustment as requested.
(4) utilize lining rope-angle scale-band scale slide rail casing system to measure ground fissure level and perpendicular displacement.
(5) simple in structure, installation, convenient disassembly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Number in the figure: 1 is self-advancing type soil anchor, and 2 is first support, and 3 is angle scale, and 4 is lining rope, and 5 is first pulley, and 6 is the pulley fixed bar, and 7 is the slide rail type suspending hammer, and 8 are band scale slide rail case, and 9 is geometrical clamp, and 10 is second support, and 11 is second pulley.
Embodiment
The present invention is further described below in conjunction with drawings and Examples.
Embodiment 1: in Fig. 1, self-advancing type soil anchor 1 screws in self-advancing type soil anchor 1 in the stratum, ground fissure both sides as fixed pedestal, and angle scale 3 is installed in second support, 10 tops, and this second support 10 is installed on the self-advancing type soil anchor 1.First pulley 5 is installed in first support, 2 tops, and second pulley, 10 usefulness pulley fixed bars 6 are fixed on second support 10, and this second support 10 is fixed on the self-advancing type soil anchor 1.Slide rail type suspending hammer 7 one ends connect lining rope 4, put into band scale slide rail case 8.Band scale slide rail case 8 usefulness geometrical clamps 9 are fixed on first support 2.Lining rope 4 is fixed in second support, 9 tops by second pulley 11, first pulley 5.Index dial 3 initial angles shown in initial reading and the lining rope 4 shown in recording strip scale slide rail case 8 scales.When local flaw level tension, no vertical movement, angle scale 3 reading no changes, slide rail type suspending hammer 7 rises, and record is scale reading shown in the slide rail type suspending hammer 7 at this moment, is ground fissure tension displacement with the initial reading difference.When ground fissure has vertical displacement, angle scale 3 readings and initial reading difference are vertical move angle, measure two ground fissure width between the self-advancing type soil anchor 1 this moment, multiply by the trigonometric function tangent value of vertical move angle, be vertical displacement, calculate the poor of reading shown in the slide rail type suspending hammer 7 and initial reading, if equate with the vertical displacement value, explanatorily the crack does not have horizontal shift, if it is unequal, the difference of the two is ground fissure horizontal shift value, illustrate this moment ground fissure be level to vertical compound motion.If lining rope 4 can not satisfy the range needs, can change easily.After the monitoring task was finished, monitoring device on the detachable native anchor screwed out native anchor, reuses.
