Concrete carbonation depth measurement device required for safety inspection and diagnosis and carbonation depth measurement method using the same

摘要

The present invention relates to an apparatus for measuring the depth of carbonation in concrete necessary for safety inspection and diagnosis and a method for measuring the depth of carbonation using the same. It is about a new concept of technology that measures depth easily and accurately. The carbonation depth measuring device disclosed in the prior art has a large error in the measured value by measuring and confirming the discoloration of the milling powder from the outside, and the measurement module is composed of a number of components, so the structure is complicated, and the size is large. It weighs a lot and causes a problem in that the manufacturing cost increases. The present invention is a method for alleviating this problem by attaching the reference plate shaped on one side of the measuring instrument body to the tip of the perforated hole of the concrete structure, and in the process of pushing the depth bar of the vernier caliper built into the measuring instrument body into the hole. 1 After confirming that the pointer coupled to the measurer has reached the point of discoloration while visually checking the observation mirror through the reflection action leading to the 1 reflector, the second reflector and the observation mirror, accurately measure the carbonation depth displayed on the LCD screen of the vernier caliper. It is characterized by devising the technology to enable measurement.
