Description
Technical field
This utility model relates to the safe field of detecting in rock stratum, particularly relates to a kind of rock stratum sedimentation protection detection device.
Background technology
In industry, above bridge, tunnel, tunnel, hoistway etc., low side employing pours arched concrete or academic title's I-steel at present
As load overcoat, any performance is not the most all had to support problem according to structure design in early stage, but, pushing away over time
Moving and crustal movement geological changes, the stress of the diverse location of arched concrete can change, and dangerous situation once occurs, it is simply that nothing
The loss that method is retrieved, the monitoring of existing rock stratum is to install survey meter in important support position, but, this monitoring mode is the most complete
Face, rock stratum landslide may be in non-supported position, and therefore, the detection in prior art settled rock stratum exists incomplete technology and asks
Topic.
Utility model content
This utility model embodiment provides a kind of rock stratum sedimentation protection detection device, solves in prior art rock stratum

Detailed description of the invention
This utility model embodiment, by providing a kind of rock stratum sedimentation protection detection device, solves in prior art rock
The detection of layer sedimentation incomplete technical problem.
In order to solve above-mentioned technical problem, below in conjunction with Figure of description and specific embodiment to above-mentioned technology
Scheme is described in detail.
A kind of rock stratum sedimentation protection detection device that this utility model provides, as it is shown in figure 1, include fibre optic interferometer, light
Feedback box 101, GPZ 102, this fibre optic interferometer include bonder 103, waveguide modulator 104, beam splitter 107, in
Sensing optical fiber that roundabout arrangement is layed in rock stratum and optical fiber end block 105, this GPZ 102 connects light feedback box
101, this light feedback box 101 connects bonder 103, and bonder 103 connects waveguide modulator 104, waveguide modulator 104 connects and divides
Bundle mirror 107, beam splitter 107 connects sensing optical fiber one end, and this optical fiber end block 105 connects the sensing optical fiber other end, this sensing
Optical fiber includes the first optical fiber 1061 and the second optical fiber 1062 be arrangeding in parallel, and this optical fiber end block 105 is for by the first optical fiber
1061 and second optical fiber 1062 concatenate so that sensing optical fiber formed loop.
Specifically, this GPZ 102 includes coherent laser.
Specifically, this sensing optical fiber is S-type roundabout arrangement in rock stratum, as shown in Figure 1.So so that sensing optical fiber energy
Enough it is distributed in rock stratum each local, it is simple to detect without dead angle.
Another way, this sensing optical fiber is roundabout arrangement in spiral shape in rock stratum, as in figure 2 it is shown, equally so that sensing
It is local that optical fiber can be distributed in rock stratum each, it is simple to detects without dead angle.
In a particular embodiment, this coherent laser launch beam of laser, feed back box 101, bonder through light
103, waveguide modulator 104, be divided into the first laser and the second laser through beam splitter 107 again, the first laser is by the first optical fiber 1061
Entering and feed back to light feedback box 101 through the second optical fiber 1062, this second laser and the first laser are in reversely, by the second optical fiber
1062 enter and also feed back to light feedback box 101 through the first optical fiber 1061, due to this sensing optical fiber in rock stratum in roundabout arrangement, energy
Enough be laid in any one position conplane, rock stratum, therefore, when there is sedimentation in any one position in this rock stratum, and should
Sensing optical fiber can detect, and feeds back to GPZ 102 through light feedback box 101, will sensing by this GPZ 102
The signal of optical fiber feedback is launched, it is achieved the comprehensive detection without dead angle.
Although having been described for preferred embodiment of the present utility model, but those skilled in the art once knowing substantially
Creative concept, then can make other change and amendment to these embodiments.So, claims are intended to be construed to bag
Include preferred embodiment and fall into all changes and the amendment of this utility model scope.
