Carbonation Depth Measuring Device for Safety Diagnosis of Concrete Structures

摘要

The present invention, a hopper member that is in close contact with the outer wall of the concrete structure to provide a closed space, and prevents the sample crushed and scattered from the concrete structure from scattering into the atmosphere; An awl member installed so as to be able to move forward or backward from the center of the hopper member to the outer wall of the concrete structure to collect a sample while crushing the concrete structure; A driving motor that provides power so that the awl member moves forward or backward; A storage case providing a storage space to collect samples scattered inside the hopper member, and connected to communicate with the hopper member; A vacuum providing unit for providing a vacuum pressure to a working space formed between the hopper member and the outer wall of the concrete structure to collect the sample scattered from the inside of the hopper member into the storage case; By supplying the air inside the hopper member to the tube member provided on the rim of the hopper member by the vacuum providing unit, the gap between the hopper member and the concrete structure is closed, and a sample is formed at the interval between the hopper member and the concrete structure. A sealing part that prevents the loss from being lost; And a reagent supply unit configured to determine whether carbonation has occurred while checking a color change of the sample by spraying a reagent onto the sample sucked into the storage case.
