As background technique is introduced, many deficiencies exist in the prior art, in order to solve technical problem as above, this
Application proposes a kind of intelligent box beam visual defects detection device and method greatly.
At present in box-beam structure, relatively common several box beam Appearance quality defects include comprising whiting of seeping water, seep water,
Surface weathering, the corrosion of dew muscle, the swollen, voids and pits of concrete rust, hole, crack etc..
Infiltration whiting refers to that white alkali trace occurs in box beam surface；Total alkali in producing cause raw material and mixing water
It is bigger than normal.
Surface weathering refers to some visual defects formed due to weathering.
Voids and pits refers specifically to concrete surface and lacks slurry, stone exposing depth greater than 5mm, but it is thick to be less than cover to reinforcement
Degree；Pitted skin refers to that the scarce slurry of concrete surface is coarse, and countless small concave points is presented in surface, and without dew muscle phenomenon；Generate cellular original
Because having: concrete does not feed intake (starch less, stone more) accurately by match ratio；Concrete mixing time is short, and stirring is uneven, makes when pouring
It is few at starching some position stones more；Concrete is not layered blanking and pours；The blanking drop height that freely inclines is spent greatly, and aggregate point is caused
From；After concrete enters mould, quality of vibrating is poor, causes leakage or over vibration.2. causing box beam surface the reason of pitted skin occur has: template
Rough, unclean, concrete surface is glued bad when demoulding；Casting concrete front template is wet not enough, and component surface is mixed
The moisture for coagulating soil is sucked, and keeps concrete dehydration excessive；Template gap is excessive, causes template spillage；There is pitted skin；Release agent applies
Brush it is irregular, part leakage brush or failure；Concrete surface and template bond；Concrete vibrating is not firm, and bubble is not discharged, rests on
Template surface.

Clod contains clod or sundries etc..2. concrete mixing is uneven, the slump is too small.3. reinforcing bar is intensive inside box beam, and selects
Coarse aggregate size it is bigger than normal.4. when concreting, a blanking is excessive, cannot sufficiently vibrate.
Dew muscle refers to that main reinforcement, construction muscle or the outer muscle of hoop are exposed at concrete surface.Leakage when producing cause makes framework of steel reinforcement 1.
Cushion block is shifted when putting cushion block or casting concrete, reinforcing bar is made to be close to template.2. concrete component section is small, and reinforcing bar is intensive,
Coarse aggregate size is bigger than normal, and concrete is caused to be difficult to fall.3. the concrete leakage at protective layer position or leakiness of vibrating.
Crack refers to the crackle gap that box beam concrete roof is formed because cracking separation.Mainly there are thermal cracking, drying shrinkage
Crack caused by the reasons such as crack and external force.Producing cause box beam concrete roof due to temperature, humidity change, supporting deformation,
Demoulding is too early, maintenance is bad etc. is likely to cause crack.
Concrete rust is swollen to refer to that concrete surface appears reinforcing bar trace on the outside of box beam, but is not dew muscle；1. producing cause is made
Cushion block is shifted when cushion block or casting concrete are put in leakage when making framework of steel reinforcement, reinforcing bar is made to be close to template.2. concrete component section
It is small, and reinforcing bar is intensive, coarse aggregate size is bigger than normal, and concrete is caused to be difficult to fall.3. the concrete leakage at protective layer position or vibration
Smash leakiness.
