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

Abstract

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; the product anti-cracking ability is good; noise in the pile driving process can be greatly reduced; concrete can be poured after pile driving is carried out, and the hollowportion can be reserved according to the work condition and design requirements; the pile body wall is adopted as one part of the pile, and the wall protection function of the whole pile is achieved;and multiple piles can be spliced through upper flanges and lower flanges.

Description

technical field [0001] The invention relates to a prestressed concrete composite pile, in particular to a prestressed concrete composite pile which is prestressed and stretched by a post-tensioning method. Background technique [0002] The traditional pile is generally a whole. Due to its large size and heavy weight, it brings a lot of inconvenience to transportation. Even if it is constructed on site, there will be many problems such as low standardization and poor quality of construction products. During construction, due to relying on hammering the pile body wall to squeeze the whole pile into the soil layer, it will also cause a lot of noise. Power loss affects construction efficiency. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art and provide a deconstructed finite element assembled prestressed pile with high degree of standardization and good quality of construction products suitable for sin...
