Put the chuck part 16 in the steel pipe piece 8 and grip the rib 11,
The penetrator 13 is hoisted, the hoisting winches 15 and 15 'are moved, and the steel pipe piece 8 hoisted together with the penetrator 13 is conveyed to the setting position and set (the connecting portion of the steel pipe piece 8 is welded), and the vibrating penetrator. This is done by repeating the process of activating 13 to carry out the set amount of penetration.

も能率的である。(Effect of the Invention) As is apparent from the above description, the method for placing a steel pipe of the present invention has ribs installed in advance on the inner rear portion of the steel pipe piece, and the chuck portion of the penetrating machine is placed inside the steel pipe piece. Put the rib in and grab the rib, and in this state, that is, with the penetrator attached in a low position upward, the steel pipe piece is transported from the temporary storage place to the setting point and set, so there is no height restriction in the construction space. Not only is it possible to add and pour relatively long steel pipe pieces at a certain location, but it is also efficient because the steel pipe pieces can be carried and set immediately for immediate penetration, and the steel pipe pieces can be placed at the placement point. Since it is temporarily placed in a recess in a nearby temporary storage place while standing in a low posture, it is possible to easily and quickly perform the work of inserting the chuck part of the penetrator into the steel pipe piece and grasping the rib without any trouble. And steel pipe It takes less time to bring the sprue to the pouring position, which is also efficient.
