Description
Technical field
The utility model belongs to Bridge Crack detection technique field, more particularly, to a kind of Bridge Crack detection means.
Background technology
Nowadays, continuing to develop with bridge technology, not only bridge total kilometrage number is also increasing year by year, and bridge
Length is also lengthened therewith, and bridge is also built in the place of some bad environments.Bridge is the throat of traffic, along with existing
The volume of traffic increases rapidly, the increasing of heavy vehicle, the overweight transport of hypervelocity of vehicle, cause the bearing capacity of bridge to be difficult in adapt in friendship
Lead to increasing rapidly for load, bridge works easily in the state of excess load for a long time crack occurs；Geology residing for other bridge
The influence of various factors, will also result in Bridge Crack during condition, orographic condition, weather conditions and design, construction, operation
Produce, the generation of Bridge Crack not only reduces the bearing capacity of bridge floor, also result in moisture and harmful substance is penetrated into, trigger reinforcing bar rotten
Erosion or the natural aging for accelerating concrete, so as to damage the bearing capacity of bridge, easily trigger security incident, therefore to bridge
Crack carries out effective detection, and crack is found in time and is administered, it is ensured that bridge is in normal operating condition, making for bridge is improved
Use the life-span.
At present, the detection of Bridge Crack is mainly using tape measure, hand-held crack observer and machine vision etc., and these are detected
Device is primarily present problems with：
First, the traditional detection of Bridge Crack is mainly measured by human contact's formula, and staff is usually to use
Tape measure carries out field survey and recorded, and the Bridge Crack of straight length and bridge can only measure to(for) Irregular Bridges crack split
The estimate of slit width degree, when Bridge Crack is more, the workload manually measured is just quite big, in addition, bridge it is general away from
The height on ground is higher, and not only difficulty is big for manual measurement, and safety coefficient is not high；This method for bridge detection no matter
There is in human and material resources or on the time very big consumption, measurement process often has human error in addition.By artificial indefinite

Second, at present, Bridge Crack of the hand-held crack observer to estimating under bridge is mainly taken in Bridge Crack detection
Crack Detection is carried out, then needs staff to take traditional axle inspection driver and shakes hands and hold crack observer, and be located at staff
Bridge Crack is detected under bridge, Bridge Crack detection is finally completed.But in actual bridge detection process, due to having one
Situations such as detection environment is complicated under a little cross-line bridges and bridge, staff is located at relatively hazardous under bridge so that Crack Detection difficulty is very
Greatly, in addition, the width of Bridge Crack specific region can only be detected for the hand-held crack observer in Irregular Bridges crack, bridge is caused
Beam Crack Detection to size results there is deviation, so as to influence safe bearing capacity to judging bridge structure and assess bridge
Quantity of operation assessment result.
3rd, Bridge Crack is detected using machine vision, digital image processing techniques are based primarily upon to photographing
Crack treatment handled, so as to obtain the width in crack, length, area and girth, but at crack pattern picture
A kind of during reason is that the crack pattern picture typically used is all the crack pattern picture photographed under ideal environment, and what is photographed splits
It is the gem-pure crack of a line edge to stitch photo, almost without burr；It is another to need in hand labeled crack pattern picture
Burr, is eliminated, the need for both modes can not all meet Practical Project, and workload is big, efficiency is low, and the detection of measurement
It is inaccurate, it is impossible to provide effectively foundation for objective evaluation pavement quality, science decision maintenance management scheme.Therefore, study
A kind of Bridge Crack detection means, is realized to the automatic detection of Bridge Crack, reduce it is artificial participate in, Bridge Crack is carried out and
When, accurate detection, realize the information measurements such as the width and length of Bridge Crack, improve the operating efficiency of Bridge Crack detection work
With the reliability of measurement data.
