Abstract

A method of inspecting a reinforced concrete pipe, comprising the steps of inspecting the deteriorated state of the reinforced concrete pipe (100) from the inside thereof by using an impact elastic wave test means having a hammering mechanism (10) and a signal receiving mechanism (20) or an appearance inspection means (30) to confirm the presence or absence of the deterioration and rank the degrees of advancement of the deterioration, selecting detail-searched portions in an inspection area from the searched results, performing a structural analysis for the selected searched portions by using data on pipe thickness, reinforcement diameter, and reinforcement arrangement to calculate the pipe strength of the reinforced concrete pipe, and using the calculated results as information for evaluating the deteriorated state of the reinforced concrete pipe.
