Method and Device for Localizing Anomalies Located Inside a Hollow Structure Located on Bare Ground and/or Buried
First Claim
1. A method for externally localizing anomalies located in a hollow structure laid on bare ground and/or buried, which anomalies have already been detected beforehand by a device moving inside said hollow structure, and positioned by counting, from an origin, marks located at regular intervals, accessible from the inside and from the outside of said hollow structure,said method consisting of:
- a. defining by counting from the same aforesaid origin, a mark accessible from the outside of the hollow structure,b. positioning a transponder module on the aforesaid mark,c. identifying the transponder module by an identification code,d. determining the number of marks separating said anomalies and said identified transponder module.

Abstract
The invention relates to a method of externally locating anomalies inside a hollow structure which is positioned on and/or below the ground (PL), wherein said anomalies have been previously detected by a device (RTE) moving inside the hollow structure and positioned by counting a series of reference marks from an origin, said reference marks being located at regular intervals and being accessible from the inside and outside of the hollow structure (PL). The inventive method comprises the following steps consisting in: a. defining by means of courting a reference mark, starting from said origin, which is accessible from outside of the hollow structure; b. positioning a transponder module (T) on said reference mark; c. identifying the transponder module (T) by an I.D. code; and d. determining the number of reference marks separating the anomalies and the identified transponder module (T).
