Inverted T-shaped prestressed double-section support pile

Abstract

A reversed-T-shaped pre-stress double-joint supporting pile comprises an upper section pile and a lower section pile. The reversed-T-shaped pre-stress double-joint supporting pile is characterized in that a notch is formed in the lower end of the upper section pile, a notch is formed in the upper end of the lower section pile, the upper section pile and the lower section pile are of a reversed-T-shaped section, a pile body is used as a pre-stress steel strand of a main rib and is arranged on one side with a flange, and the upper section pile and the lower section pile are integrally connected in an abutting mode oppositely. The pre-stress steel strand is used as the main rib, the steel using amount of the supporting pile is greatly lowered, and manufacturing cost is lowered.

Description

technical field [0001] The invention relates to the field of building prefabricated components, in particular to a prestressed support pile. Background technique [0002] Traditional support piles include non-prestressed rectangular support piles, bored piles and steel sheet piles. Non-prestressed rectangular support piles are usually prefabricated on the construction site, which has a long manufacturing period and high cost. When the pile length is long, piling 1. It is difficult to transport the piles. In order to meet the lifting and transportation, there are many additional reinforcements, and the bending stiffness is small and the deformation is large. The symmetrical reinforcement method is adopted, which does not conform to the bending moment envelope diagram of the support piles, resulting in a huge waste of main reinforcement. In addition, the rectangular support piles are easy to leak soil between the piles, and the performance of transmitting soil arching is poor,...

AI Technical Summary

Problems solved by technology

[0002] Traditional support piles include non-prestressed rectangular support piles, bored piles and steel sheet piles. Non-prestressed rectangular support piles are usually prefabricated in layers on the construction site, which has a long manufacturing period and high cost. When the pile length is long, piling 1. Difficult to transport piles. In order to meet the requirements of hoisting and transportation, there are many additional reinforcements, and the bending stiffness is small and the deformation is large. The symmetrical reinforcement method is adopted, which does not conform to the bending moment envelope diagram of the supporting piles, resulting in a huge waste of main reinforcement.

In addition, the rectangular support piles are easy to leak soil between the piles, and the performance of transmitting soil arching is poor, so the pile distance is limited to a certain extent

An inverted T-shaped prestressed double-joint support pile with low cost and good performance in transmitting soil arch action has not been reported yet.
