Description
Technical field
The present invention relates to hydro-structure safety monitoring field more particularly to a kind of arched concrete dam underwater crack are automatically controlled touring
Monitoring device and its application method.
Background technique
The Crack Monitoring of arched concrete dam is the pith of dam structure safety monitoring.The deformation of concrete material vulnerable to
Temperature influences, and when the thermo parameters method of concrete structure is uneven, the state of different parts expansion or shrinkage is different, therefore
Surface of concrete structure can generate thermal cracking.The characteristics of being built in the arched concrete dam of High aititude cold district be, dam site
Region day and night temperature is big, which makes the dam surface of arched concrete dam easily generate thermal cracking.Therefore it seeks
It asks one kind specifically for extremely frigid zones arched concrete dam runtime crack on dam surface monitoring device and its application method, is hydro-structure
Safety monitoring area research personnel for Crack Monitoring direction under extreme condition research hotspot, to the peace of arched concrete dam structure
Full stable operation also plays an important role.
In general, hydro-structure Crack Monitoring project implementation is to bury crack gauge by monitoring position in certain emphasis, so
And this mode can only be monitored the cracking state at the certain positions in dam body inside, the practical function of Crack Monitoring receives limit
System, therefore how the coverage area of vee crack monitoring becomes the direction that structural safety monitoring technical staff studies.In addition, upper
In the conventional fracture monitoring mode stated, crack gauge once breaks down or damage is not easy to place under repair and replace, therefore, with
The survival rate of the growth of arched concrete dam runing time, crack gauge will be reduced constantly, and the quality of Crack Monitoring project can not obtain
To guarantee.Third, the monitoring quantity of crack gauge are crack opening degree, can not fracture number and crack specific form supervised
It surveys, reinforcement recovery foundation cannot be provided to the crack on dam surface problem of extremely frigid zones arched concrete dam runtime.
Monitoring for crack number and form, the mode of mainstream is still that diver's Portable device dives into the water to dam at present
Face carries out inspection.The identification to dam facing micro-cracks may be implemented in the mode of manual inspection, but asks there are still following
Topic: first, manual inspection is stronger for the specialty background of practical operation personnel, and the human error in practical operation and assessment is difficult to keep away
Exempt from；Second, there are certain risk for diving inspection, and especially with the construction on extra-high dam in recent years, the depth of diving is even wanted
Reach rice up to a hundred, difficulty is increasing；Third, it is difficult to the crack information for recording entire dam facing of system, and dam facing is carried out
Holistic modeling.
With the development of unmanned air vehicle technique, engineers and technicians are begun trying in such a way that underwater unmanned plane takes pictures inspection
Bridge pier crack is monitored, but due to the complexity of the environment such as underwater flow velocity, patrol unmanned machine pinpoints cruise under water
Precision is difficult to ensure always.In addition, the equipment required precision such as camera for Crack Monitoring is higher, quality usually than heavier, because
This purchases in practical projects while ensureing that the unmanned plane price of load-bearing capacity and cruising ability is prohibitively expensive.Third, underwater ring
It is easier dam facing safety problem occur when border is severe, and underwater unmanned plane is difficult to the Scene realization fixed point cruise in bad environments.
Insufficient for conventional fracture monitoring covering surface, monitoring quantity is single and manual inspection and unmanned plane monitor stability
The disadvantages of insufficient, can carry out all standing shooting to concrete dam facing using underwater high-definition camera, in conjunction with image processing techniques
Analysis is monitored to dam surface crack.

Simultaneously general work personnel check underwater photography image effect by VR equipment.
(6) by video cache, compression after shooting, while the position data of acquisition position sensor collection will shoot image
Data and position data packing are uploaded to web server and data server.
(7) monitoring management personnel download corresponding data on a web server and handle, and video format is converted to picture first
Format then carries out binary conversion treatment to picture, deletes the abnormal picture selected to derivation program after picture analyzing by program, supervises
It surveys administrative staff and artificial judgment is carried out to abnormal picture, finally store the data for analyzing result and analytic process to data service
Device.
(8) threedimensional model is established to arched concrete dam, Crack Monitoring data is imported into model database, carry out finite element structure meter
Point counting analysis.
(9) user terminal can check threedimensional model and Crack Monitoring as a result, checking model database, examine to monitoring information
Rope realizes monitoring data visualization.
