Problems solved by technology

The prefabricated square pile mainly has the following defects: ①Low production efficiency and long production cycle; ②The product quality is unstable, and there are many air holes in the hardened concrete structure section; ③The strength of the concrete is low, and the bearing capacity of the pile body cannot be fully utilized; ④Concrete The natural maintenance time is long, and the production area is large
Its disadvantage is that the production process is complicated, the production is time-consuming and laborious, and the production cost is relatively high.

Abstract

The invention discloses a manufacturing method for an anti-seismic and anti-cracking concrete square pile. The manufacturing method for the anti-seismic and anti-cracking concrete square pile is characterized by comprising the steps, carried out in sequence, of concrete mixing ratio designing, pouring, reinforcement inserting, tensioning, centrifugal shaping and high-pressure maintaining, the step of the tensioning uses multi-stage type gradient tensioning, and a step of natural maintaining is carried out before the step of the high-pressure maintaining. The manufacturing method for the anti-seismic and anti-cracking concrete square pile comprises the steps, carried out in sequence, of the concrete mixing ratio designing, the pouring, the reinforcement inserting, the tensioning, the centrifugal shaping and the high-pressure maintaining, the step of the tensioning uses the multi-stage type gradient tensioning, and the step of the natural maintaining is carried out before the step of the high-pressure maintaining; accordingly, the integral strength of the square pile is greatly improved, the connecting cost of pipe point components is lowered, and the penetrating power of the square pile is improved.

Description

technical field [0001] The invention relates to a method for manufacturing an anti-seismic and anti-cracking concrete square pile, which belongs to the field of building construction. Background technique [0002] Prefabricated concrete square piles are prestressed concrete hollow square piles (inner cavity mainly adopts pre-installed rubber inflatable method, with square or rectangular cross-section forms) except for prestressed concrete hollow square piles which adopt pretensioning process for the foundation of port engineering. Most of the foundation works are mainly manual work Most of the non-prestressed and vibrating forming processes in the country, the concrete adopts natural curing, and the structure is mostly a solid square cross-section. The prefabricated square pile mainly has the following defects: ①Low production efficiency and long production cycle; ②The product quality is unstable, and there are many air holes in the hardened concrete structure section; ③The ...
