s2, drilling: the first driving motor (5) drives the driving screw (4) to rotate and drives the extension shaft (23) to fall, so that a designated area is drilled, meanwhile, the vacuum suction pump (14) operates, the drilling position of the drill bit (24) is sucked through the cooperation of the connecting pipe (13) and the extension hose (19), and the polished stone particles are sucked, so that the punching operation is completed;
s3, pouring preparation: taking down the vacuum suction pump (14), taking out the connecting pipe (13) and the extension hose (19) simultaneously, and extending to the inside of the supporting rotating shaft (22) and the connecting pipe (13) through an output pipeline of external pouring equipment;
s4, pouring: concrete is poured into the holes through external equipment, and the support sliding frame (6) is slowly lifted at the moment according to the pouring speed of the concrete and matched with the pouring height in the holes.
