STEEL PIPE PILE, CONNECTING ROD, AND METHOD FOR PULLING OUT STEEL PIPE PILE
To provide a steel pipe pile, a connecting rod, and a method for pulling out the steel pipe pile, which can efficiently pull out the steel pipe pile buried in the ground with a relatively small force.SOLUTION: A steel pipe pile 10 includes a hollow pile main body 11 and an engaging portion 12 provided at the tip of the pile main body 11. The engaging portion 12 has an engaging space 12c communicating with the inside of the pipe of the pile main body 11, and engaging means 12a provided on the inner surface of the engaging portion 12. A connecting rod 20 includes a hollow rod main body 21 that can be inserted into the pipe from the head of the steel pipe pile 10, and a connecting end 22 attached to the tip of the rod main body 21, and has a structure capable of engaging with the engaging portion 12 by inserting the connecting end 22 into the engaging portion 12 at the tip of the steel pipe pile 10 and rotating it on the outer circumference of the connecting end 22. A method for pulling out the steel pipe pile 10 comprises an insertion step for inserting the connecting rod 20, a connecting step for connecting the connecting end 22 to the engaging portion 12, an edge cutting step for cutting the edge of the steel pipe pile 10 with the surrounding ground, and a pulling out step for pulling out the steel pipe pile 10.SELECTED DRAWING: Figure 1
【課題】地中に埋設した鋼管杭を比較的小さな力で効率的に引き抜き可能な、鋼管杭、連結ロッド、及び鋼管杭の引抜き方法を提供する。【解決手段】鋼管杭１０は、中空の杭本体１１と、杭本体１１の先端に設けた係合部１２と、を備え、係合部１２は、杭本体１１の管内と連通する係合空間１２ｃと、係合部１２の内面に設けた係合手段１２ａと、を有する。連結ロッド２０は、鋼管杭１０の頭部から管内に挿入可能な中空のロッド本体２１と、ロッド本体２１の先端に付設した連結端２２と、を備え、連結端２２の外周に、連結端２２を鋼管杭１０先端の係合部１２内に挿入して回転させることによって、係合部１２と係合可能な構造を有する。鋼管杭１０の引き抜き方法は、連結ロッド２０を挿入する挿入工程と、連結端２２を係合部１２に連結する連結工程と、鋼管杭１０を周囲の地盤との縁を切る縁切り工程と、鋼管杭１０を引き抜く引き抜き工程と、を備える。【選択図】図１
