The utility model relates to the technical field of floor tile hollowing detectors, and discloses a floor tile hollowing
detector for
engineering supervision, which comprises a floor tile hollowing detection device, a quick marking mechanism is arranged on the right side of the top of the floor tile hollowing detection device, and the quick marking mechanism comprises a liquid
pigment storage box. The bottom of the liquid
pigment storage box is connected with the right side of the top of the floor tile hollowing detection device, the upper end of the outer wall of the liquid
pigment storage box is in threaded connection with a pressing, extracting and spraying
assembly, and a lengthened connecting column is installed at the top of the pressing, extracting and spraying
assembly. The quick marking mechanism can extract liquid pigment in a liquid pigment storage box by pressing a pressing extracting and spraying
assembly and spray the liquid pigment to the hollow floor tile through a lengthened spraying
pipe for marking, and a
detector does not need to bend to mark the hollow floor tile, so that the floor tile hollowing detection efficiency is improved, and the labor intensity of the
detector is reduced. And the body health of a detector is also facilitated.
