MAINTENANCE MANAGEMENT METHOD OF CONCRETE STRUCTURE

摘要

To perform degradation diagnosis in reinforcement work of a concrete structure by effectively using concrete cores collected by drilling a hole for embedding reinforcement members.SOLUTION: Maintenance management data of a concrete structure are collected by using concrete cores collected in a drilling step. A sensor for collecting the maintenance management data of the concrete structure is embedded in a core drilled hole when performing post-installed reinforcement member construction in the core drilled hole, to collect the maintenance management data of the concrete structure using the sensor. The collected maintenance management data include data of at least compression strength, amount of chloride ions and neutralization depth. The collected maintenance management data are associated with 3D model data of the concrete structure and managed.SELECTED DRAWING: Figure 1
