Description
Technical field
Utility model device be related to constructing tunnel and detection field more particularly to it is a kind of two lining cavity detection it is portable
Self- steering imaging device.
Background technology
China's rapid development of economy brings volume of traffic sharp increase, causes to build tunnel in complicated geological area as normal
State, and under the rigor condition in complicated geological area, dash forward mud, the vault of water burst that the increase of tunnel width brings bigger cave in
Risk.
Tunnel-liner at present is both designed as composite lining, and II, III grade of lining of country rock two bears 30% country rock under normal circumstances
Relaxation load, IV, V grade of country rock two, which serves as a contrast, bears the 50% of country rock relaxation load.It is by combined type when design structure analysis calculates
Lining cutting backfills closely knit, lining cutting behind country rock behind can provide the consideration of radial elastic drag.Therefore, whether after two backing of arch
Come to nothing or two backing of abutment wall after the harm come to nothing, change two lining structure stress, so that two lining local pressures is increased, cause
Security risk.It comes to nothing after two backing of arch then security risk bigger.When secondary lining vault comes to nothing, arch is sagging moment
That is arch upper limb tension, routinely arrangement of reinforcement arch upper limb be unworthy of steel bar stress, this will make arch upper limb crack in tension, cause to ooze
Leak and corrosion reinforcing bar, and then secondary village's building concrete is made to destroy.On the other hand, after secondary lining vault comes to nothing, country rock loses
Go due protection and supporting, may make country rock it is loose and deformation increase, and then lead to wall rock destabilization, fall off destruction.Therefore, two
Secondary lining cutting top lay falling-off phenomenon must be prevented and be handled.
The mass defect of two lining crown concrete cavities is usually present in tunnel double-lining work progress, defect hiding is in two linings
Inside concrete can not use naked eyes to be observed, and according to radar into Scanning Detction, not only operating performance is cumbersome, analyze data
Time is long, while at high price.Practice of construction scene is substantially rule of thumb punching and detects and estimate, and carries out at grouting
Reason holds slurry pressure with grouting quantity and grouting and determines whether cavity is full.Therefore, be badly in need of it is a kind of it is cheap, simple in structure just
The cavity situation that portable device pair two serves as a contrast concrete carries out detection of knowing the real situation.
Utility model content
Technical problem to be solved in the utility model is in tunnel double-lining work progress, and crown concrete cavity causes
Quality defect of concrete can not effectively observe, to can not effectively solve the tunnel double-lining construction quality that concrete cavity is brought
Problem.
In order to solve the above technical problems, the technical solution adopted in the utility model is：It provides a kind of two and serves as a contrast cavity detection
Portable self- steering imaging device, including infrared camera, screw shell, pipe type cable line and imaging device；The screw-casing
Tube top portion is equipped with self-contained idler wheel, and side is equipped with opening, the reflex reflector lens tilted down, the infrared camera are equipped in opening
It is wrapped in the screw shell bottom and alignment reflex reflector lens, the infrared camera is filled by pipe type cable line and the imaging
Set connection.
Particularly, the imaging device is also connect with storage facilities.
Particularly, it is additionally provided with LED light pearl around the infrared camera.
Compared with prior art, the utility model has the beneficial effects that：Apparatus structure is simple, of low cost, is not destroying
Under the premise of concrete appearance, have the function of that Visual retrieval two serves as a contrast crown cavity；And the device has the function of self- steering, it can
Various visual angles shooting cavity inside situation；Two lining cavity defects can also be directed to and carry out image data retentions, according to image data data,
Instruct rockfill grouting.
Description of the drawings
Fig. 1 is utility model device front view.
Fig. 2 is utility model device side view.
Wherein, infrared pick-up head -1；Screw shell -2；Self-contained idler wheel -3；Reflex reflector lens -4；Pipe type cable
Line -5；Imaging device -6；LED light pearl -7.
Specific implementation mode
Below in conjunction with attached drawing, the utility model is described in further detail.
There are one self-contained idler wheels 3 for the setting of utility model device camera front, convenient for infrared camera 1 in helix tube
It is steadily moved in cavity under the package of set 2 and does not damage camera.Infrared camera 1 is encased for 2 by screw shell, and in spiral shell
The lateral opening of rotation set pipe 2 carries out image reflection using the reflex reflector lens 4 of the tilted setting of casing, infrared camera is aligned
The downward reflex reflector lens 4 of the minute surface so that infrared photography, 1 can observe the cavity environment around the present apparatus, when environment not
Suitable for being observed with infrared camera 1 as ambient temperature is excessively high, when can be impacted to the observation of infrared camera 1,
Light environment can be provided by the LED light pearl 7 around camera, light reflexes to two lining cavitys by the reflex reflector lens being obliquely installed
In, to obtain the result of normal observation；After infrared camera 1 enters cavity along built-in pipe, the self-conductance at 2 top of screw shell
Camera is changed direction and imported in cavity by formula idler wheel 3, passes through the adjustable shooting of pipe type cable line 5 after twisting, rotating camera
Position and direction achieve the effect that two lining cavity of multi-faceted observation, camera are transmitted after image collection by data cable
It is stored to storage facilities to imaging device 6, and by image data, reaches visualization visual inspection two and serve as a contrast cavity and storage concealment
The effect of defect image data provides data for follow-up rockfill grouting.
Compared with prior art, utility model device can play visual under the premise of not destroying concrete appearance
Change the effect of two lining crown cavity of detection；And the device has the function of self- steering, can shoot cavity inside situation from various visual angles；It can also
Image data retention, which is carried out, for two lining cavity defects instructs rockfill grouting according to image data data.
