Preparation method of concrete square pile mould

Abstract

The invention discloses a preparation method of a concrete square pile mould. The preparation method comprises the following steps: pre-arranging a plurality of separating rods in a steel mould, pouring molten iron into the steel mould, cooling and molding the molten iron in the steel mould to obtain a mould framework; drawing out the plurality of separating rods from the steel mould, forming a plurality of accommodating cavities for accommodating the concrete square piles in the mould framework; and opening the side mould in the steel mould, blocking each accommodating cavity, punching compressed air into the steel mould, and separating the steel mould from the mould framework to obtain the concrete square pile mould. According to the preparation method of the concrete square pile mould disclosed by the invention, the concrete square piles are produced by adopting a technical mode of prefabricating a mould, so that the concrete square piles are unified in specification, the construction cost is lowered, the condition that a filling core of reinforced concrete is pulled out is avoided, and the reliability of the concrete square piles is improved.

Description

technical field [0001] The invention relates to a preparation method of a concrete square pile mold. Background technique [0002] Concrete square piles are an important part of building foundations. They not only carry the superstructure, but also need to ensure the stability of the superstructure. In recent years, more concrete square piles have been used in various foundation projects, because concrete square piles are generally prefabricated in factories or cast on site. At present, the prefabricated concrete square piles in the factory are likely to cause the length of the single pile to be too long and the specifications are not uniform, resulting in high engineering cost and easy to pull out the reinforced concrete core, causing the concrete square pile to fall from the abutment, column, Beams are separated, which leads to engineering quality and safety accidents. [0003] Therefore, prior art awaits further improvement and development. Contents of the invention ...
