摘要
To provide a concrete structure crack survey method capable of accurately surveying a crack state even if corner chipping occurs at a crack location as a result of drilling. A concrete structure crack survey method (SA) includes a first boring step (S1) in which a hole of a survey-subject depth is bored in a concrete structure, injection steps (S2, S3) for injecting a liquid material having a specific color upon curing into the hole bored in the first boring step, a second boring step (S4) for reboring a hole having a larger hole diameter than that of the hole into which the liquid material was injected in the injection step after the liquid material has been cured, and detection steps (S5-S7) for inserting an imaging device into the hole bored in the second boring step and detecting cracking by detecting the specific color.
