Composite foundation pile with lower portion enlarged diameter section and construction method of composite foundation pile
The invention discloses a composite foundation pile with a lower portion enlarged diameter section and a construction method of the composite foundation pile. The composite foundation pile comprises a precast concrete pile body, and a cast-in-place pile is arranged on the outer side of the lower portion of the precast concrete pile body. The construction method comprises the following steps that (1) a hole is formed by a drilling machine or manually; (2) mechanical or manual chambering is conducted on a soil layer below a soft soil layer; (3) cured materials are poured into the hole; and (4) the precast concrete pile body is implanted into the hole. Compared with a pile body of a single diameter and the same length, the bearing capacity of the composite foundation pile with the lower portion enlarged diameter section is greatly improved, the pile is shorter on the premise of meeting the requirement of designed bearing capacity, and the playing capacity of side resistance and tip resistance of a pile foundation is improved.
