摘要： PURPOSE: To simplify installation and removing operation to a ground by installing a guide-pipe fixing device body into a hole section for mounting formed to the propul sion object ground and setting up a mounting section, an abutting surface section and a projecting-retracting operation mechanism to the main body. CONSTITUTION: A hole section H for mounting is formed previously to a ground J. A first mounting section 18 for fitting a guide pipe G is attached to a guide-pipe fixing device body 17. A pair of abutting surface sections 19 freely pushed against the surface section 16 of the hole section H are arranged before and behind the main body 17. A projecting-retracting operation mechanism 20, by which the abutting surface sections 19 are projected and retracted freely in the direction of abutment on the surface section 16 of the hole section H, is installed among the surface sections 19 and the main body 17. A fixing device T is lowered, and a grounding section is placed on an excavating base section. The guide pipe G is arranged, and set up to the mounting section 18. A bolt for the operation mechanism 20 is screwed and forwarded, and the surface sections 19 are pushed against the surface section 16 of the hole section H while being projected in the direction of abutment respectively, and the guide pipe G is fixed. Accordingly, high propulsive reaction is ensured in the guide pipe G, and propulsive operation can be carried out by strong propulsive force.

摘要： PURPOSE: To increase the accuracy and efficiency of a thrusting work, by setting a thrust control pitch in accordance with the position of a thrusting head in the ground and the positional deviation from the planed line and controlling the operating direction and quantity of a pressure-receiving slope with a fuzzy rule. CONSTITUTION: The position of a thrusting head 4 in the ground is measured by use of a transmitting coil C1 to calculate the positional deviated distance between the position and the planed line. The thrust control pitch, or the distance to the next measuring position, is set small when the deviation is large and the thrusting body S is advanced by application of a fuzzy rule. After that, the deviation is checked at the next measuring position to get the deviated figure. The same control is performed in accordance with the figure. In this time, when the deviated figure is small, the thrust control pitch is set longer and the arrival position is estimated at every minimum thrust control pitch within the thrust control pitch and further, a fuzzy rule is applied on the basis of the thrust position to get the next minimum thrust control pitch.
