Description
Technical field
The present invention relates to construction engineering technical fields, it particularly relates to a kind of filling of the underwater reinforced concrete column of sleeve
Slurry compactness inspection method.
Background technique
It builds and is reinforced in industry in China, it is always a stubborn problem that submerged structure, which is reinforced, and what is used for a long time encloses
With the period, long, at high cost, place is limited the shortcomings such as big to weir method for strengthening.Due to fibrous composite have specific strength it is high,
The advantages of good corrosion resistance, rising in recent years utilize fibrous composite sleeve underwater reinforced concrete column method, however
In practical operation, not exclusively, surface damage concrete cannot remove clean and sealing part for concrete column polishing when due to starting
Stainless steel lag screws many reasons such as are not tight seal and the compactness of construction quality especially its grouting material are made to be difficult to be guaranteed.
In addition, the existing underwater reinforced concrete post detection of fibrous composite sleeve is confined to artificial random coring more,
It with certain blindness, cannot find the problem to the greatest extent, leave hidden danger to engineering structure.
Summary of the invention
For above-mentioned technical problem in the related technology, the present invention proposes a kind of grouting of underwater reinforced concrete column of sleeve
Expect compactness inspection method, the above-mentioned deficiency of the prior art can be overcome.
To realize the above-mentioned technical purpose, the technical scheme of the present invention is realized as follows:
A kind of grouting material compactness inspection method of the underwater reinforced concrete column of sleeve, comprising the following steps:
1) diver measures the size of concrete column after reinforcing under water, and carries out by origin of concrete column geometric center
Computerized three-dimensional modeling；
2) measuring point that detection is chosen on computer model is equally divided into model surface first, in accordance with pulse area equal principle
Several regions 150mm × 150mm, are numbered each region and are incorporated into Excel table, included using computer Excel
The point of program arbitrary extracting 5% (no less than 3) is as measuring point；
3) selected measuring point is detected using ultrasonic wave detector, detection method is plane to the method for survey；
4) ultrasonic test data is analyzed, the smallest 3 measuring points of velocity of wave is chosen, to the ultrasonic wave of this 3 measuring points
Location site coring where receiver and transmitter, core diameter 100mm, coring depth be grouting material thickness add 50~
100mm；
5) core sample is processed, being fabricated to side length is cube of the 70mm with grouting material surface layer, then further to band
Grouting charge level is cut, and "convex" shaped standard sample is become；
6) core sample is carried out pull-out test and recorded to destroy position, if three samples draw bad position in column original coagulation
On soil, then it represents that grouting material perfusion is closely knit；Otherwise indicate that leakiness is perfused in grouting material.
Beneficial effects of the present invention: the measuring point of ultrasound examination, which is chosen, has more randomness, and measuring point can be represented preferably
The construction quality of concrete column is horizontal after entire reinforcing；The selection purpose of live coring point is stronger, super with a batch by detecting
Quality in sound wave measuring point is most not good enough, helps to find the problem to the full extent, greatly improves the meaning of quality testing.
