DIRT REMOVING DEVICE AND DIRT REMOVING METHOD FOR STEEL PIPE SHEET PILE WELL FOUNDATION
To makes it possible to easily and reliably remove dirt when constructing a steel pipe sheet pile well foundation without using a special-shaped dirt removing device.SOLUTION: A dirt removing device for a steel pipe sheet pile well foundation has a vertically penetrating pipe insertion hole 50 provided at a steel pipe sheet pile 10 side from a wale 20 of a timbering installed on the inner peripheral surface of a well (steel pipe sheet pile 10), a high pressure water injection pipe 60 that is inserted in the pipe insertion hole 50 and injects high pressure water toward the inner peripheral surface of the well (steel pipe sheet pile 10), and a high pressure water supply device 90 that supplies the high pressure water to the high pressure water injection pipe 60. The high pressure water injection pipe 60 has multiple high pressure water injection holes 70 provided at a tip thereof with equal intervals in the circumferential direction. Each of the high pressure water injection holes 70 has at least an opening 70b in the lateral direction and an opening 70c in the obliquely upward direction.SELECTED DRAWING: Figure 1
【課題】 鋼管矢板井筒基礎を構築する際に、特殊な形状の土ベラ落とし装置を用いることなく、容易かつ確実に土ベラ落としを行うことができるようにする。【解決手段】 井筒（鋼管矢板１０）の内周面に設置する支保工の腹起し２０よりも鋼管矢板１０側に設けた、上下方向に貫通するパイプ挿通孔５０と、パイプ挿通孔５０に挿通して、井筒（鋼管矢板１０）の内周面に向かって高圧水を噴射する高圧水噴射パイプ６０と、高圧水噴射パイプ６０に高圧水を供給する高圧水供給装置９０とを備える。高圧水噴射パイプ６０は、その先端部において周方向に等間隔で設けた複数の高圧水噴射口７０を有している。各高圧水噴射口７０は、少なくとも、横方向の開口７０ｂ、斜め上方向の開口７０ｃを有している。【選択図】 図１
