Abstract
An abrasion detecting apparatus is configured to detect the abrasion of a component of a cutter head of a tunnel boring machine, which is configured to excavate ground using a cutter to bore a tunnel. The abrasion detecting apparatus includes an abrasion detection probe located rearward of a front end of the cutter by a predetermined distance and located forward or rearward of a front end of the component, whose abrasion is to be detected, of the cutter head by a predetermined distance, where the abrasion detection probe includes an abrasion detecting portion at a front end portion thereof. The abrasion detecting portion abrades away by contact with the ground to be excavated. The abrasion detecting apparatus also includes a detecting device configured to detect an abrasion of the abrasion detecting portion.
