[0020] Embodiment: This embodiment is a surface quality detection device for concrete pouring, which is used for deep concrete surface quality detection of cast-in-place columns. Figure 1 and Figure 2 As shown, the detection device includes an aluminum alloy frame 1 and a transparent window placed in the center of the aluminum alloy frame. The bottom of the casting template 2 of the above-mentioned cast-in-place column is designed with an opening 21, and a plurality of fixing bolts 4 perpendicular to the surface of the casting template are installed on the outer edge of the opening. A through hole 11 is designed in the center of the above-mentioned aluminum alloy frame, and slots 12 surrounding the through hole are respectively designed on both sides and the bottom edge of the through hole. Transparent resin glass 3 is inserted in the slot, and the transparent resin glass covers the through hole and forms a transparent window. The space between the transparent plate and the above-mentioned slot and the top gap are filled with waterproof sealant. The transparent window can observe the surface of the cast-in-place concrete in the casting template. The back of the aluminum alloy frame is designed to coincide with the above-mentioned opening and The vertical plate 13 encloses the opening, and the vertical plate is perpendicular to the surface of the aluminum alloy frame. The depth of the vertical plate matches the thickness of the above-mentioned casting template. The surface of the aluminum alloy frame located at the outer edge of the vertical plate is designed with a mounting hole 14 corresponding to the above-mentioned fixing bolt and can be sleeved on the fixing bolt. The back vertical plate of the aluminum alloy frame is inserted into the opening and screwed to the above-mentioned casting template through the fixing bolt. A process hole 15 is also processed on the surface of the aluminum alloy frame located at the outer edge of the vertical plate. A waterproof breathable valve 5 for exhaust and drainage is installed in the process hole. The inner surface of the aluminum alloy frame is installed with a filter cover corresponding to the inner end of the waterproof breathable valve and covering the inner end of the waterproof breathable valve. The inner surface of the aluminum alloy frame is coated with a layer of release agent.

[0021] When using, such as Figure 3 and Figure 4As shown, a hole is opened at a height of 20CM from the ground at the lower part of the casting template of the cast-in-place concrete column, and corresponding fixing bolts are embedded around the opening. Then, a waterproof breathable valve is screwed into the process hole of the aluminum alloy frame, and a filter cover is installed at its inner end. Then, the vertical plate of the aluminum alloy frame is aligned and inserted into the opening. At the same time, the mounting holes of the aluminum alloy frame are aligned and inserted onto the fixing bolts, and the nuts are screwed into the fixing bolts and tightened to ensure that the aluminum alloy frame is firmly installed on the casting template. Next, transparent resin glass is inserted into the slots on the aluminum alloy frame, and waterproof sealant is applied at the joints to complete the installation of the entire detection device. When pouring and vibrating the concrete column in the template, the inspection personnel can observe the apparent quality of the deep concrete in the template in real time through the transparent window, understand the quality of the concrete in the deep layer of the column, and subsequently observe the initial setting quality of the concrete. The water vapor in the cast-in-place concrete can be discharged from the template in time through the waterproof exhaust valve. After the template is removed, the aluminum alloy frame can be removed for the next use due to the effect of the release agent.
