#CMT# #/CMT# The mark i.e. boundary mark (8), has a block (10) including a base (13) that is traversed by a notched central hole (5) in which a metallic anchoring tube (12) is projected. A discoid or circular signing support incorporates an electronic circuit that stores and exchanges data. An annular space is arranged between the support and the tube. The support is centered on the tube. The support is arranged at a distance ranging from 30 to 40 millimeters, from the top (11) of the block. #CMT# : #/CMT# An independent claim is also included for a method for fabricating a geodesic or topographic mark. #CMT#USE : #/CMT# Geodesic or topographic mark i.e. boundary mark, for use by entitled geographic or geodestic service for officially griding an extended region, and for marking underground electricity or gas network. #CMT#ADVANTAGE : #/CMT# The annular space is arranged between the support and the tube, thus avoiding electromagnetic interference with the tube. The circular signing support guarantees better reliability of exchanging the data with wireless transmitter/receiver type transmission tools adapted to an entitled person, irrespective of position around the mark. The support is arranged at a distance ranging from 30 to 40 millimeters, from the top of the block, thus permitting the support to be perfectly accessed and detected by the transmission tools adapted to the person and to be protected against exterior aggression. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a transversal sectional view of a boundary mark. 5 : Notched central hole 8 : Boundary mark 10 : Block 11 : Top 12 : Metallic anchoring tube 13 : Base. |
