a prefabricated square pile upright post is a square reinforced concrete post, and a reinforcement cage and a steel lattice post are arranged inside the prefabricated square pile upright post; the steel reinforcement cage is a square steel reinforcement cage, the steel reinforcement cage is formed by welding a plurality of longitudinal steel reinforcements through transverse steel reinforcements, and the steel lattice column is formed by welding 4 angle steels through a plurality of flat steels; the steel reinforcement cage is butted with the steel lattice column and is connected with the steel lattice column through a connecting steel bar in a welding mode, the connecting steel bar is located at the angle position of the steel reinforcement cage and the steel lattice column, the connecting steel bar, the steel reinforcement cage and most of the steel lattice column are covered by concrete, an exposed lattice column section of 200-300 mm is arranged at the upper end of the steel lattice column, and the exposed lattice column section is combined with a supporting beam into a whole when in use.
The optimization scheme is as follows: the side length of the square reinforced concrete column is 500-600 mm, and the side lengths of the reinforcement cage and the steel lattice column are 50-80 mm less than that of the square reinforced concrete column.
Further optimizing the scheme: the length of steel lattice column is greater than 2000mm, the edge width of angle steel is 120 ~ 180mm, and the width of band steel is 100 ~ 200 mm.
When the method is applied specifically, a static pressure pile machine is adopted to carry out static pressure construction on the prefabricated square pile stand column, the prefabricated square pile stand column is inserted into an underground designated position, the upper end face of the prefabricated square pile stand column is flush with the bottom face of a supporting beam to be supported, the construction process is mature and reliable, the work efficiency is high, and the method is more convenient and faster compared with a conventionally used construction process of a lattice column and a cast-in-place pile or a steel pipe concrete column.
The utility model is not only safe and reliable, but also can be prefabricated in factories, the site construction is rapid, the construction period can be greatly shortened, the project progress is accelerated, and the economic benefit is improved.
