one end of the bearing frame (1) is fixed on the pile driver base (7), the other end of the bearing frame extends to the upper portion of the base, and the first fixing seat (21) is located at one end, far away from the base, of the bearing frame (1).
7. A cement mixing pile construction method using the cement mixing pile machine according to claim 6, comprising the steps of:
leveling the foundation, and ensuring that the levelness error of the foundation is less than 2 degrees;
paying-off measurement and positioning;
entering a pile driver, correcting a drill shaft (51) of the pile driver, and enabling the perpendicularity error of the drill shaft (51) to be smaller than 1 degree;
positioning a pile driver;
stirring and sinking, lifting and spraying, stirring and sinking again, and lifting and spraying again;
and (6) testing the bearing capacity of the cement mixing pile.
8. The cement mixing pile construction method according to claim 7, wherein: when the pile machine enters the field, a bearing platform (6) is paved, and a pile machine base (7) and a drilling frame are hoisted;
when the drill frame is installed, the relative inclination between the drill shaft (51) and the bearing frame (1) is observed, so that the verticality of the bearing frame (1) is adjusted.
