FLUID INJECTION DEVICE OF STEEL PIPE PILE FOR ROTATION PRESS FIT AND ROTATION PRESS FIT CONSTRUCTION METHOD OF STEEL PIPE PILE
PROBLEM TO BE SOLVED: To facilitate installation and improves of a degree of freedom of a fluid supply pipe for supplying and jetting a fluid for assisting rotation press fit of a steel pipe pile, and thereby enhance efficiency of a fluid auxiliary rotation press fit construction method.SOLUTION: A fluid injection device 1 of a steel pipe pile for a rotation press fit which is mounted on a steel pipe pile 10 and supplies and jets a fluid for assisting rotation press fit of the steel pipe pile includes a plurality of fluid supply pipes (20 and 30) which are connected to a fluid supply source, form a flow passage feeding a fluid from the fluid supply source, are provided with a jet port of the fluid, and extend to a longitudinal direction of the steel pipe pile. At least two fluid supply pipes (20 and 30) are parallel pipes which are independently separated from each other and provided in parallel with each other, and are installed in the steel pipe pile so that the outer peripheral surfaces are brought into contact with an inner peripheral surface of the steel pipe pile. The parallel pipes have a depth position in a jet direction from the jet port and a longitudinal direction of the steel pipe pile of the jet port, or a degree of freedom such that the fluid supply sources to be connected are different.SELECTED DRAWING: Figure 1
【課題】鋼管杭の回転圧入を補助するための流体を供給し噴射する流体供給パイプの設置の容易化、自由度の向上を図り、もって流体補助回転圧入工法の効率化を図る。【解決手段】鋼管杭１０に装備され、当該鋼管杭の回転圧入を補助するための流体を供給し噴射する回転圧入鋼管杭の流体噴射装置１は、流体供給源に接続され、流体供給源からの流体を給送する流路を形成し、該流体の噴射口が設けられ、鋼管杭の長手方向に沿って延設される流体供給パイプ（２０，３０）を複数本備える。少なくとも２本の流体供給パイプ（２０，３０）は、互いに独立分離して並列に設けられる並列パイプであるとともに、共にその外周面が鋼管杭の内周面に接して鋼管杭内に設置されている。この並列パイプは、互いに噴射口からの噴射方向、噴射口の鋼管杭の長手方向に沿った深さ位置又は接続される流体供給源が異なるという自由度を備える。【選択図】図１
