【発明の詳細な説明】
（発明が属する技術分野）
本発明は、例えば橋梁の下のように、上方に既設構造物
があって施工空間に高さ制限がある場所で、複数の鋼管
ピースを順次継ぎ足しながら打設する工法に関するもの
である。Detailed Description of the Invention (Technical field to which the invention pertains) The present invention is directed to the construction of a plurality of steel pipe pieces in places where there is an existing structure above and the height of the construction space is limited, such as under a bridge. This relates to a construction method in which concrete is poured in succession.

と、上方の空間が狭くなるため、貫入機（例えば振動式
貫入機）の使用が難しい。(Problems to be solved by the invention and its features) In the method of pouring a plurality of steel pipe pieces by successively joining them, it is advantageous to use long steel pipe pieces unless there is a problem in handling. When a long steel pipe piece is set in a driving position in a place where there is a height restriction, the space above becomes narrow, making it difficult to use a penetrating machine (for example, a vibrating penetrating machine).
本発明は、前述の問題点の解決を図ったものであって、

ものである。That is, the present invention lowers the posture of the penetrating machine by inserting the chuck part of the penetrating machine into the steel pipe piece and grasping the ribs installed in advance in the deep inner part of the steel pipe piece, thereby limiting the height in the construction space. This makes it possible to use a penetrating machine to perform additional installation of relatively long steel pipe pieces even in certain locations.
