Method for constructing knotted cast-in-place concrete-based pile, and excavation blade-equipped steel pipe
This method for constructing a knotted cast-in-place concrete-based pile comprises: a step for preparing an excavation blade-equipped steel pipe (10) in which a leading end excavation blade (12) is detachably attached to the lower end thereof; a step for inserting the excavation blade-equipped steel pipe (10) into the ground (15) while excavating downward by the leading end excavation blade (12) and forming a spiral groove in soil around the periphery of the steel pipe (11) by pushing down the excavation blade-equipped steel pipe while rotating the excavation blade-equipped steel pipe around the center axis of a steel pipe (11) in a given direction; a step for filling mortar or ready-mixed concrete into the steel pipe (11); and a step for pulling out only the steel pipe (11) from the ground (15) and pouring the mortar or ready-mixed concrete in the steel pipe (11) into a pile hole (17) that is formed after the steel pipe (11) has been pulled out and the spiral groove (16). The leading end excavation blade (12) may be freely housed in the steel pipe (11) instead of being detachable.
