[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The hardened concrete thickness detection device realizes the measurement of the thickness of concrete through structures such as a cylinder and a motor. The motor drives the column head to rotate, and the cylinder moves the column head to the position of the outer ring of the motor output shaft. When the cylinder drives the column head to break through the concrete, the column head is pulled out, the tape measure is pulled out, and the position where the brush hairs on the outer ring of the column head are contaminated with concrete dust is measured. The thickness of the concrete can be specifically obtained, which has the effect of measuring the thickness of the concrete.
[0013] 2. The hardened concrete thickness detection device absorbs dust during concrete drilling by setting up a box body, a storage chamber and other structures to avoid exposure to the atmosphere. When drilling concrete, concrete debris and dust rise through the annular groove of the column head and enter the storage chamber, where they are collected centrally. When the measurement is completed, the dust and debris inside the storage chamber can be poured out to check the content and proportion inside the concrete, thereby achieving the effect of absorbing dust during drilling.

[0022] The cylinder start block 13 is pressed to move the column head 9 out of the device. The outer ring bristles of the column head 9 adhere to the concrete and soil dust and debris. By judging the color of the concrete dust, the tape measure 15 is pulled out from the pull port 16 to the lowest end of the concrete color, thereby measuring the thickness of the concrete.
