Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.

Fig. 1 shows a schematic distribution diagram of a plurality of detection devices in a concrete protective material spraying area, embodying the implementation state of the detection method of the present invention at the construction site.

Before the protective material spraying is carried out on a concrete protective material spraying area 1, a plurality of detection devices (with acid-base test paper) 2 are approximately uniformly stuck in the area, and the proportion of the detection devices covering the spraying area is less than 1%. Preferably, the detection means is substantially rectangular in shape and has an area of about 6cm²～18cm²The length is about 3-6cm, and the width is about 2-3 cm.

When the protective material is sprayed on the acid-base test paper and the surface of the concrete around the acid-base test paper, the unit area spraying amount of the protective material sprayed on the acid-base test paper can reflect the unit area spraying amount on the surface of the concrete around the acid-base test paper. Meanwhile, the protective material sprayed on the surface of the surrounding concrete can permeate into the concrete covered below the test paper from the edge of the acid-base test paper.

The design standard of the detection device is that the total area covered in the area range is as small as possible, the area of each detection device is also as small as possible, so that materials sprayed on the surrounding concrete surface can uniformly penetrate into the concrete area covered by the detection device to form uniform protection as possible, the area covered by the acid-base test paper is relatively small, the amount of the protective materials penetrating into the area covered by the acid-base test paper is basically the same as that of the surrounding area, and the protective effect of the protective materials on the area is not influenced. Meanwhile, the color development area of the acid-base test paper on each detection device is not too small, so that the color change is suitably observed by human visual observation.

The acid-base test paper is an important means for detecting the spraying amount of the protective material. In the embodiment of the utility model, the object of detection is the inorganic silicate capillary crystalline type water solution concrete protective material of nanometer modification, and this kind of protective material spraying is itself colorless on the concrete surface. The characteristic that the material can make the test paper develop color after contacting with the acid-base test paper is utilized, so that the spraying amount per unit area is displayed as the color change of the acid-base test paper, and the standard of the spraying amount is converted into the color standard of the color change of the acid-base test paper. In the embodiment of the utility model, when the spraying amount of the nano-modified inorganic silicate permeable crystallization type aqueous solution concrete protective material reaches the standard, the acid-base test paper becomes deep red.

Of course, the utility model discloses not being restricted to the inorganic silicate infiltration crystallization type aqueous solution concrete protective material that modifies to the nanometer, when material and the contact of acid-base test paper that other spraying operations used can produce regular colour change, all can adopt the utility model discloses a spraying volume is detected to the scheme.

The acid-base test strips are preferably evenly distributed in the spray area, although this is not strictly required to be even, but generally even, and the entire area can be detected.

And after the acid-base test paper is well adhered, spraying a concrete protective material. General construction requires that the protective material be sprayed at least twice. In order to ensure the construction quality, the quality manager will make a request for each spraying amount. Therefore, the acid-base test paper is compared with the color chart after each spraying to see whether the color standard is met, namely whether the spraying amount standard is met.

Therefore, when the detection method of the utility model is adopted, the acid-base test paper is usually removed from the spraying area after each spraying. And before the next spraying, sticking new acid-base test paper again, and removing the acid-base test paper again after the next spraying is finished. After each construction, whether the spraying quantity standard is met or not can be determined by means of the color development condition of the acid-base test paper, the spraying is supplemented under the condition that the spraying quantity standard is not met until each position in the spraying area meets the standard, and then the acid-base test paper is removed.

After the acid-base test paper is removed, the acid-base test paper can be subjected to position marking and stored for later engineering acceptance. The acid-base test paper can be removed by directly removing each detection device and directly storing, or the acid-base test paper can be separately removed from the detection device and stored. The latter can more conveniently remove the acid-base test paper from the concrete spraying area and reduce the cost of the detection device.

Fig. 2 shows a schematic structural diagram of the middle detecting device of the present invention. As shown, the detection device 2 includes a waterproof base 21, a front cover 22 and a card seat 23. In fig. 2, the waterproof base 21 is covered by the front cover 22, and the specific structure can be seen from fig. 4.

The holder 23 includes a receiving groove 231 capable of receiving the waterproof base 21 and the front cover 22. The waterproof base 21 and the front cover 22 are stacked in the width direction of the receiving groove 231, and the stacked thickness of the waterproof base and the front cover is equal to the width h of the receiving groove 231, that is, h is h1+ h 2. Therefore, the

end parts

214, 224 are reliably held in the containing groove 231, so that the two are not easy to separate from each other, and when the

end parts

214 and 224 need to be disassembled, the waterproof base 21 and the front cover 22 can be conveniently disassembled only by taking the clamping seat 23 off the

end parts

214 and 224, and the acid-base test paper in the waterproof base 21 and the front cover 22 can be taken out.
