| titleOfInvention | Excavation blade mounting steel pipe for construction of cast-in-place concrete pile and construction method of cast-in-place concrete pile |
| abstract | [PROBLEMS] To be able to build a concrete pile for ground reinforcement with stable quality without being affected by soil conditions at the site, and to construct a concrete pile easily and reliably on site. We provide drilling blade-mounted steel pipes for building cast-in-place concrete piles. An excavating blade-attached steel pipe 1 includes a steel pipe 10 and a distal excavating blade 20 that is detachably attached to the distal end of the excavating blade and has an excavating blade body 22 on the distal end surface. The protrusion 13 is provided on the inner peripheral surface of the tip of the steel pipe 10, and the tip excavation blade 20 is brought into contact with the protrusion 13 when the steel pipe 10 rotates in a predetermined rotation direction, and the tip excavation blade 20 is rotated integrally with the steel pipe 10. A rotation receiving portion 23a is provided. The rotation receiving portion 23a is separated from the inner peripheral surface of the steel pipe 10 toward the steel pipe center side.
