摘要： PROBLEM TO BE SOLVED: To provide pipe propulsion technique for injecting mud forming material so as to be able to economically produce mud of excellent plastic fluidity without depending on intuition and experience of an operator. SOLUTION: A succeeding pipe is connected to the rear of a guide body, and while driving it forward an excavated hole is excavated by a cutter head to bury the succeeding pipe in the ground. In this process, mud forming material is injected in excavated sediment to produce mud with plastic fluidity, and this mud is filled in an annular gap between the guide body and the excavated hole and taken in from a sediment intake of the guide body so as to be force-fed to the ground. In a pipe propulsion machine of such constitution, the guide body is provided with a front side earth pressure gauge 1 and a rear side earth pressure gauge 2 respectively measuring mud pressure on the tunnel face side and sand intake side of mud passing the annular gap. The pipe propulsion machine is provided with a controller 3 having a judging part 4 for computing the difference between both mud pressure measured by the earth pressure gauges 1, 2 and inputted and comparing the computed result value with the preset threshold value, and a command part 5 for controlling a mud forming material injection device 6 so that the former value approaches the latter value on the basis of the compared result, thus adjusting the injection quantity of the mud forming material.
