To explain with reference to FIG. 10, FIGS.
FIG. 10 is a schematic enlarged cross-sectional view taken along the line 10-10 of FIG. 5, showing a position correction state of the pipe P, and FIG. 10 (A) shows a state where the guide pipe G is driven into the ground without error. Indicates
For example, when the pipe P is inserted into the lower portion of the guide pipe G as shown by the chain line in the figure, four expansion parts 16 are provided on the upper, lower, left and right sides.
By expanding u, 16d, and 16l, 16r to substantially the same size, the pipe P is moved and corrected as shown by the solid line so that its center Op coincides with the center Og of the guide pipe G, and these are expanded. Four expansion parts 16u, 16d, 1
The pipe P can be fixed in the guide pipe G by 6l and 16r. Further, as shown in FIG. 10 (B), when the guide tube G is lowered from the normal position by a distance d, the lower inflating portion 16d is large, the upper inflating portion 16u is small, and the left and right inflating portions 16l are , 16r are expanded to substantially the same size, the pipe P can be moved upward and corrected to be fixed at a predetermined position in the guide pipe G.
As shown in 0 (C), when the guide tube G is lifted upward from the normal position by the distance d, the upper inflating portion 16u
Is large, the lower inflating portion 16d is small, and the left and right inflating portions 16l, 16r are inflated to substantially the same size, whereby the pipe P can be moved downward and corrected to be fixed at a predetermined position in the guide pipe G. Further, as shown in FIG. 10 (D), when the guide tube G is bent and driven to the right by the distance d, the right inflating portion 16r is enlarged and the left inflating portion 16l is enlarged.
Is small, and the vertical inflating portions 16u and 16d are inflated to substantially the same size, whereby the pipe P can be moved to the left and corrected to be fixed at a predetermined position. Further, as shown in FIG. As shown, when the guide pipe G is bent to the left by a distance d, the left inflatable portion 16l is large, the right inflatable portion 16r is small, and the vertical inflatable portion 16 is further inflated.
By expanding u and 16d to substantially the same size, the pipe P can be moved and corrected to the right and fixed at a predetermined position. As described above, the four expansion parts 16u, 16
By individually expanding and controlling d, 16l, and 16r to a predetermined size, the pipe P can be moved and corrected to a predetermined position with respect to the driving position of the guide pipe G.

As described above, when the position correction device A with an air bag is used to correct the position of the first pipe P and fix it in the guide pipe G, the propulsion device D is inserted from the rear end of the opening of the pipe P, Attach this to the rear. By operating the propulsion device D as described above, the first pipe P is connected to the air bag 12 of the position correcting device A.
Then, it is driven to a predetermined position in the ground while being guided by the guide tube G. At this time, the air bag 12 of the position correcting device A comes off from the guide pipe G and comes into contact with the earth and sand and is torn, but the pipe P itself is already in the corrected position and the position is held by the earth and sand. The correction position hardly changes due to the driving movement of the pipe P (see FIG. 6).

In this case, the separated propulsion device D may be temporarily stored in the first pipe P or may be taken out into the starting shaft 1. After that, the second pipe P on the ground is lowered into the starting pit 1 and placed on the starting table 3 to be advanced, and its front end is integrated with the rear end of the first pipe P by connecting means such as welding. When the propulsion device D is attached to the rear part of the second pipe P and the propulsion device D is actuated again, the second pipe P slides on the starting table 3 and the propulsion device A is connected. At the same time, it moves forward and is gradually driven into the ground, and at the same time, the first pipe P is further driven into the ground. When the driving amount reaches a predetermined amount, the operation of the propulsion device D is stopped (see FIG. 7).
