[0037] The working method of the concrete radioactive sampling auxiliary device for house safety assessment is explained below.

[0038] like Figure 1 As shown, first, a worker uses an impact drill to drill a small hole on the work surface as a hollow hole for sampling. Then, four tile-shaped expansion pieces 416 of the positioning part 4 are inserted into the hollow hole. It should be noted that the diameter of the hollow hole is slightly larger than the outer diameter of the expansion piece 416.

[0039] Next, the dovetail screw 42 is rotated to lock the positioning part 4. At this point, the worker can directly use the electric tool to perform sampling operations in the drilling barrel 51 to obtain the concrete core. It should be noted that the electric tool is a barrel drill. During the sampling process, the handheld part 3 is used for auxiliary operation to provide stability of the operation.

[0040] After the sampling is completed, the dovetail screw 42 is loosened to unlock the positioning part 4. At this time, the entire auxiliary device is rotated around the hollow hole, for example, by 90 degrees, and the dovetail screw 42 is rotated again to lock the positioning part 4. At this time, the next sampling operation can be started.

[0041] During the rotation of the auxiliary device, the first roller 32 and the second roller 53 play a stabilizing role.

[0042] This process is repeated at least four times with the hollow hole as the center, and the concrete cores obtained from the four samples are distributed in circles at equal intervals on the working surface.

[0043] Finally, the obtained concrete core is sent to the laboratory for relevant performance tests.

[0044] The locking principle of the positioning portion 4 is described below.

[0045] like Fig.11 As shown, when the dovetail screw 42 is tightened, the head of the dovetail screw 42 hits the expansion slope 4161 of the expansion piece 416, so that the expansion piece 416 expands outward and presses against the inner wall of the hollow hole, so that the positioning part 4 is locked.

[0046] like Fig.13 As shown in the second embodiment of the main support 2, a plurality of positioning holes 211 are provided on the first long rod 21. The position of the positioning part 4 can be adjusted by using the positioning holes 211.

[0047] The concrete radioactive sampling auxiliary device for house safety appraisal has a compact structure and is easy to operate. It can ensure that the sampled concrete cores are distributed in equidistant circles on the working surface without drawing lines in advance, thereby effectively improving the efficiency of concrete sampling in house safety appraisal.

[0048] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
