Method for preparing cylindrical concrete pier column

Abstract

The invention discloses a method for making a cylindrical concrete pier column. The method includes: 1) making a cap; 2) connecting the lower end of the disassembly-free formwork with the upper end of the cap; Build pier core steel bars in the space; 4) pour concrete in the inner hole of the non-removable formwork, after the concrete solidifies, the cylindrical concrete pier column is completed, and the non-removable formwork forms the outer structure of the cylindrical concrete pier column; The beneficial technical effect is that: a method for manufacturing cylindrical concrete piers is proposed. After adopting the method, the construction period can be greatly reduced, the construction cost can be reduced, and the quality of the produced cylindrical concrete piers is better.

Description

Technical field [0001] The invention relates to a technique for manufacturing concrete piers, in particular to a method for manufacturing cylindrical concrete piers. Background technique [0002] Column-type piers are currently widely used bridge piers in highway bridges; in the prior art, when making column-type piers, generally pier body reinforcement and column templates are built on the caps. The column templates are located on the periphery of the pier body reinforcement, and finally pass through the column Concrete is poured into the formwork to form the bridge pier. After the pier is formed, the column formwork is removed; the problems are: 1) Common column formwork is generally wooden formwork or steel formwork. Wooden formwork is easily damaged during the construction process and may be damaged during the construction process. It needs to be replaced many times. The steel formwork is prone to corrosion in the underwater part, which cannot be used again, and the material ...

AI Technical Summary

Problems solved by technology

[0002] Column pier is the pier form widely used in highway bridges at present; when making column pier in the prior art, pier body reinforcement and column formwork are generally built on the cap platform, and the column formwork is located on the periphery of the pier body reinforcement, and finally passed through the column Concrete is poured into the formwork to form the bridge pier, and after the pier is formed, the column formwork is removed; the existing problems are: 1) The common column formwork is generally a wood formwork or a steel formwork, and the wood formwork is easily damaged during the construction process, and may It needs to be replaced many times, and the steel formwork is prone to corrosion in the underwater part, which cannot be used again, and the material loss is large; 2) The commonly used column formwork needs to be assembled section by section, which is prone to installation defects, causing construction joints and deformation cracks, If the joints are not strict, it is easy to cause grout leakage; 3) After the column formwork is removed, there are many joints on the surface of the pier, which affects the quality and appearance of the pier body. Therefore, after the column formwork is removed, the surface of the pier body usually needs to be modified , which is more troublesome; 4) In the column type pier project, the construction and dismantling of the column formwork are relatively cumbersome, and the amount of labor and construction period occupied are relatively large

Generally speaking, the installation and disassembly of the existing column formwork are more troublesome, the construction period is longer, and problems such as cracks on the pier body surface are prone to occur
