Concrete carbonization depth detection device

Abstract

The invention discloses a concrete carbonization depth detection device. The device comprises a drilling machine, a drill bit and a reading ruler; the drill bit is mounted on a rotating shaft of the drilling machine; the reading ruler is telescopically mounted on the drilling machine; the reading ruler and the drill bit are arranged in parallel; a central hole is formed in the center of the drillbit; the central hole is cylindrical; the central hole penetrates through one end, away from the drilling machine, of the drill bit; a long and narrow observation hole is further formed in the circumferential surface of the drill bit; and the observation hole is parallel to an axis of the drill bit. When the device is used for carrying out concrete carbonization depth detection, a large pit is notrequired to be chiseled, and the detection can be carried out only by drilling a small block on concrete, so that the damage to a concrete component is relatively small, and meanwhile, the measuringdepth is relatively large.

Description

technical field [0001] The invention relates to the field of measurement and detection, in particular to a concrete carbonation depth detection device. Background technique [0002] Carbonation depth is an important index to measure the strength and durability of service concrete. At present, the drilling method is generally used in engineering testing and existing specifications, that is, drilling holes on the detection object with an electric drill, and then spraying the concrete around the drilling hole with phenolphthalein to distinguish the carbonized area and the non-carbonated area of ​​the concrete, that is, to find out the carbonized area. Edge or carbonization boundary, and then measure with a ruler or a vernier caliper. The existing problems are that it is troublesome to dig a hole, the shape of the hole is not standard, and it is difficult to control the size. At the same time, the depth of its measurement is limited. When the carbonation depth is large, it is n...

Problems solved by technology

The problem is that it is troublesome to dig a hole, the shape of the hole is not standard and it is difficult to control the size, and the depth of its measurement is limited. When the carbonation depth is large, it is necessary to dig a large hole, which will cause great damage to the concrete components.
