Before the pile expanding equipment works, firstly installing the retaining arc plates 13 on the three fixing rods 14, and then installing the pile expanding mechanism 32 in the soil discharging through groove 28 of the cylindrical pile 5 through the matching of the supporting rod 3, the cylindrical pile 5, the second gear 18 and the inner teeth 23 in the installation groove 29; at this time, the blade 11 is moved from the inside of the cutter chamber 31 to the outside of the drill 10 by the elastic force of the spring 22; when the pile expanding equipment works, the driving motor 1 drives the first gear 17 and the third gear 20 to rotate through the rotating shaft 6, the first gear 17 drives the transmission shaft 9 to rotate around the rotating shaft 6 in a circumferential manner through the second gear 18 and the internal teeth 23 on the cylindrical pile 5, the transmission shaft 9 drives the fourth gear 21 and the drill bit 10 to rotate around the rotating shaft 6 while rotating around the rotating shaft 6, the third gear 20 drives the transmission shaft 9 to rotate through the fourth gear 21, so as to drive the drill bit 10 to rotate, the drill bit 10 drives the drill bit 10 to rotate through the drill bit bulge 12 and the blade 11 arranged at the lower end of the drill bit 10 while rotating, and simultaneously drives the drill bit 10 to rotate in a circumferential manner around the rotating shaft 6, so as to expand the pile, the soil discharged by the drill bit 10 through the rotational force by the soil discharging spiral sheet 4 while the drill bit 10 expands the stone, and the soil discharged from the circular through hole formed by the soil retaining arc, during the soil discharging process, a part of stones and soil in the soil discharging through groove 28 enter the eccentric hole 27 from the filtering hole 26, and the stones and a small part of soil can fall into the lower side of the eccentric hole 27 from the middle of the two elastic pieces 15 through the filtering of the elastic pieces 15, so that the stones and the small part of soil become a part of the pile; after the pile expansion is finished, taking the pile expansion mechanism 32 and the soil retaining arc plates 13 arranged on the three fixing rods 14 out of the soil discharging through groove 28 of the cylindrical pile 5, and then pouring cement into the soil discharging through groove 28 and the three eccentric holes 27 to form cement piles in the soil discharging through groove 28 and the three eccentric holes 27; the cement piles formed in the cylindrical piles 5 can meet the requirement of higher buildings for the stability of the foundation.
According to the invention, the pile expanding mechanism 32 can be directly arranged at the lower side of the cylindrical pile 5, the cylindrical pile 5 can be directly placed in the foundation under the action of the pile expanding mechanism 32, and the pile can be directly poured after the pile expanding mechanism 32 is taken out, so that the pile construction is completed. And the pile is put without drilling first, so that the time is saved, the efficiency is improved, and the using effect is better.
