PURPOSE: To extract the function of a leading pipe capable of correcting the propulsive direction by rocking a head sufficiently and to conduct even prior art pipe burying at a long distance. CONSTITUTION: In a measuring device for a leading pipe with a processor (f) such as a microcomputer, in which the positional information and attitude information of a leading pipe (a) are input and which freely displays these information on monitors (e) fitted at places excepting the leading pipe (a) of a shaft (c), etc., a radio transmitter 1b is mounted in the leading pipe (a) while radio transmitter 1a are set up at places excepting the leading pipe (a) of the shaft (c), etc., and these transmitters are communicated freely. A processor (f), in which all of various positional information and attitude information detected by a detecting means separately fitted into the leading pipe (a) are input through the radio transmitters 1a, is used as the processor (f). |
