Problems solved by technology

[0002] Prestressed piles include hollow prestressed piles, solid prestressed piles and partially solid prestressed piles. Different prestressed piles meet the different needs of users. Partial solid prestressed piles mean half solid and half hollow. The production of solid prestressed piles is more troublesome, the overall molding takes a long time, is more complicated, and has a short service life and lower safety in use. Therefore, we propose a partial solid prestressed pile produced by centrifugal method and its production process

Embodiment 1

[0037] Embodiment 1: a kind of part solid prestressed pile and production technology of centrifugation production, comprise the steps:

[0038] a: Material selection: cement, sand, stones, water reducing agent, rust inhibitor, third-grade threaded steel bar, and release agent, of which: cement 28%, sand 25%, stone 45%, water reducing agent 3%, rust inhibitor 3%;

[0039] b: Make concrete: Put the cement, sand and stones in step a into a concrete mixer for 20-35 minutes, and add water reducing agent and rust inhibitor during mixing to obtain the concrete used;

[0040] c: Make the cage frame: first stretch the third-grade threaded steel bars, and then weld or bundle them to make the inner steel bar cage and the outer bar bar cage, so that the inner bar bar cage is placed in the outer bar bar cage and the inner bar bar Relatively fixed, the threaded steel bars of the inner reinforcement cage and the outer reinforcement cage are parallel to form a reinforcement cage frame 3;

Abstract

The invention discloses a partial solid prestressed pile produced through a centrifuge method, and a production process, and belongs to the technical field of partial solid prestressed piles. The production process comprises the following steps of a, sorting; b, manufacturing concrete; c, manufacturing a cage frame; d, assembling a mold; e, filling the mold; f, carrying out a centrifugal molding method; g, standing; and h, demolding. An outer mold and an inner mold are adopted, and an obstruction plate is arranged in the inner mold at the same time; in the concrete feeding process, the concrete is fed into one side of an inner cavity of the inner mold, so that one half of a molded prestressed pile is solid, the other half of the molded prestress pile is hollow, the working efficiency is improved, and the molding quality is ensured; and meanwhile, the centrifugal molding method is further adopted, the concrete between the outer mold and the inner mold before centrifugal molding and theconcrete filled in one side of the inner cavity of the inner mold are filled densely, and the concrete is gathered toward a pile corner part under the effect of a centrifugal force, so that the denseness is improved, the overall strength is high, the service life is long, the quickness in demoulding is realized, and the production time is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of partially solid prestressed piles, in particular to a partially solid prestressed pile produced by a centrifugal method and a production process thereof. Background technique [0002] Prestressed piles include hollow prestressed piles, solid prestressed piles and partially solid prestressed piles. Different prestressed piles meet the different needs of users. Partial solid prestressed piles mean half solid and half hollow. The production of solid prestressed piles is cumbersome, the overall molding takes a long time, is relatively complicated, and has a short service life and low safety in use. Therefore, we propose a partial solid prestressed pile produced by centrifugal method and its production process. Contents of the invention [0003] The object of the present invention is to provide a partly solid prestressed pile produced by centrifugal method and its production process, so as to solve the probl...
