Deconstructed finite element assembled prestressed pile suitable for pile bottom hammering pile driving

The invention relates to a prestressed concrete composite pile, in particular to a prestressed concrete composite pile adopting post-tensioning method prestress tension. A deconstructed finite elementassembled prestressed pile suitable for pile bottom hammering pile driving comprises a pile body and a pile top. The pile body comprises a pile body plate I and a pile body plate II, a hollow pile body is defined by the pile body plate I and the pile body plate II, and flange structures are embedded into the top and the bottom of the pile body. The middle of the pile top is hollow consistent withthe pile body, a preformed hole allowing a longitudinal prestressed reinforcement to be inserted is formed in the pile top wall in the longitudinal direction, and transverse reinforcements are distributed in the transverse direction at certain intervals. The deconstructed finite element assembled prestressed pile has the beneficial effects that the standard degree is high, and the construction end product quality is high;
