Fabricated pile and construction method thereof

Abstract

The invention discloses a fabricated pile which comprises a lower pipe pile. A lower pipe pile reinforcing cage is arranged in the lower pipe pile, and an upper end plate is arranged at the upper end of the lower pipe pile. A top pipe pile is arranged at the upper end of the lower pipe pile, a lower end plate which is pressed on the upper end plate is arranged at the lower end of the top pipe pile, and the lower end plate and the upper end plate are connected. A top pipe pile reinforcing cage is arranged in the top pipe pile, composite stirrups shaped like a Chinese character 'jing' are arranged on the top pipe pile reinforcing cage every other 200-400 mm, and a post-poured concrete grouting core is arranged in the top pipe pile. The invention further discloses a construction method of the fabricated pile. According to the fabricated pile and the construction method of the fabricated pile, the upper fabricated pipe pile and the lower fabricated pipe pile are assembled together, and the advantages of the pipe piles and the advantages of cast-in-situ bored piles are fused together in the mode that the post-poured concrete grouting core is poured in the top pipe pile. The fabricated pile has the advantages that pile connection is simple, convenient and fast, the construction cost is low, construction is quick, the quality can be guaranteed easily, and the bearing capacity is high.

Description

technical field [0001] The invention relates to the technical fields of building construction such as bridge engineering, industrial and civil construction, and marine port engineering, in particular to an assembled pile and a construction method thereof, which can be used for load-bearing piles and weak soil support piles of various structural engineering. Background technique [0002] Prestressed reinforced concrete pipe piles are factory-produced pipe piles with maximum material properties. Its manufacturing process is simple, its adaptability is wide, and its economic benefits are high. It is widely used in soft soil foundations. However, due to the constraints of production and construction technology, the wall thickness of the pile is limited to a certain extent, so the horizontal bearing capacity of the pipe pile is relatively low. Small, the transverse bending moment is small, and the applicability is poor in pile foundations of multi-story buildings bearing horizont...
