Abstract

PURPOSE: To easily correct the advancing direction of a head by thrusting a crushing head provided in a new pipe into an existing pipe with an advancing means provided in the existing pipe for crushing, and pulling the head with a pulling means provided in the existing pipe. CONSTITUTION: The rear end section of a first new pipe 4 is thrust by an advancing means 7, an existing pipe 1 is crushed by a crushing head 10, and the first new pipe 4 is installed. A second new pipe 4 is connected to the rear end section of the first pipe 4 in a rear vertical shaft 5, then the new pipe 4 is likewise installed. The existing pipe 1 is likewise replaced with the new pipe 4, and a worker pulls a cord body 13 with a pulling means 8 according to the advancing speed of a head 10 and monitors the state of the head 10 sent from a monitoring means 14 with a television 16. When the head 10 tends to deviate from the prescribed course, the head 10 is pulled by the pulling means 8 via the cord body 13, and the head 10 is returned to the prescribed course while being applied with advancing force.
