10. The method for manufacturing a concrete square pile according to any one of claims 1 to 9, comprising the steps of:

s1: adjusting die

Adjusting the length of the mould according to the length of the manufactured concrete square pile;

s2: laying square pile framework

The deformed steel bar is used as a framework of the concrete square pile and clamped in a mould of the casting platform (1), and the deformed steel bar needs to be ensured to be positioned at the center of the concrete square pile during clamping;

s3: grouting agent

Pouring concrete slurry output by the stirrer into a mould on the pouring platform (1), and stirring the slurry in the mould in the grouting process to avoid solidification;

s4: the upper surface is smooth

After grouting is finished, repeatedly moving along the surface of the mould by using a surface leveling device (2) to level the surface of the concrete square pile;

s5: demoulding

After the concrete square pile is naturally solidified, demoulding the concrete square pile, and after demoulding, performing ash supplementing and scraping treatment on the surface of the concrete square pile;
