Complete burial. In the figure, 4 indicates the excavator, 5 indicates the vertical shaft that is the arrival base, and 6 indicates the ground. Next, as shown in the second figure, the excavator 4 is removed and a chloride pipe, a polyethylene pipe, and a polyethylene pipe having a smaller diameter than the propulsion pipe are installed inside the buried propulsion pipe 3.
A small diameter pipe 4 such as a technical steel pipe is inserted. Although the small-diameter pipes 7 are not particularly shown in the drawings, they are sequentially sealed and added in a liquid-tight manner within the oscillation base 1. Next, as shown in the third diagram, the propulsion tube 3
A filler injection pipe 9 is inserted into the cylindrical space 8 between the small diameter pipe 7 and the small diameter pipe 7.
Uncured fillers such as foamed mortar and foamed urethane lO
inject. In this embodiment, when injecting the filler 10, water is injected into the small diameter pipe 7 to approximately half of the inside of the small diameter pipe 7.
It was used to keep the surface level. Next, as shown in the fourth figure, the propulsion tube 3 is pulled out using a jack I installed on the side of the shaft 5 which is the arrival base. Incidentally, the propulsion tube 3 may be pulled out while the filling material 10 is injected into the voids generated when the propulsion tube 3 is pulled out. Then, as shown in Figure 5, the filling material 1
Complete the construction of the small diameter pipe with the effect of 0. Note that the filler 1o may be injected into the void even after the propulsion tube 3 is pulled out, if necessary.

Therefore, small-diameter pipes with excellent liquid tightness such as PVC pipes can be used, and meandering of the propulsion tube can be corrected by inserting an inner tube, preventing water leakage at the joint due to meandering of the propulsion tube. It is possible to construct small-diameter pipes without defects that cause water leakage, and it is also possible to propel long distances and curves, and it is also possible to construct small-diameter pipes with cross-sectional valve types. The type of propulsion device can also be small in diameter according to the diameter of the propulsion pipe, and can be used for sewage, communications,
It has the advantage that multipurpose pipes such as water supply can be arranged in one propulsion pipe, and furthermore, the propulsion pipe can be reused.
