JOINT PROTECTION STRUCTURE FOR ROTARY PILES
To improve workability and suppress friction of a joint structure by reducing the resistance arising from ground resistance during installing in a mechanical joint structure having a part protruding outward from an outer peripheral surface of a steel pipe in a rotary pile.SOLUTION: The present invention discloses a joint protection structure for rotary piles, which is a joint protection structure provided adjacent to a mechanical joint structure for rotary piles, wherein the mechanical joint structure includes a part formed at an end of the rotary pile and protruding outward from the outer peripheral surface of the rotary pile, and the joint protection structure comprises a plurality of ribs protruding outward in a radial direction of the rotary pile and arranged in a circumference direction of the rotary pile.SELECTED DRAWING: Figure 1
【課題】回転杭において鋼管の外周面よりも外側に張り出した部分を有する機械式継手構造で打設時の地盤の抵抗によって生じる抵抗を低減することによって、施工性を向上させ、かつ継手構造の摩耗を抑制する。【解決手段】回転杭の機械式継手構造に隣接して設けられる継手保護構造であって、上記機械式継手構造は、上記回転杭の端部に形成され、上記回転杭の外周面よりも外側に張り出した部分を有し、上記継手保護構造は、上記回転杭の径方向外側に突出し、上記回転杭の周方向に配列される複数のリブを備える回転杭の継手保護構造が提供される。【選択図】図１
