[0002] The pile foundation consists of piles and pile caps, see pile foundation. Pile construction methods are divided into two categories: precast piles and cast-in-place piles. In addition to the engineering geological conditions, the selection of the piling method must also consider the type, cross-section, length, site environment and design requirements of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. During the construction of the pile foundation, the pile body needs to be fixed to prevent the pile body from settling or tilting, which may cause problems with the construction quality.

[0003] Most pile foundation structures are cylindrical structures. The center of gravity varies with the height of the pile foundation. The existing method of fixing the pile body is to assemble the fixing structure on site according to the outer diameter of the pile body.

When burying the pile body 4, the guide assembly 1 below is used to limit and guide the pile body 4 to prevent the pile body 4 from tilting, thereby improving the burying quality of the pile body 4. The fixing assembly 2 applies a locking force to the outside of the pile body 4 to fix the pile body 4 and improve the stability of the pile body 4.

When the first driven gear 16 rotates, the guide positioning rack 17 is driven to slide along the sliding groove through the meshing between the teeth.

[0059] When the guide assembly 1 guides the pile body 4, the guide block 172 at one end of the multiple sets of guide positioning racks 17 forms a structure that adapts to the outer circle of the pile body 4. When the pile body 4 is buried, the pile body 4 is limited and guided by the multiple sets of guide blocks 172. The outside of the pile body 4 contacts with the multiple sets of balls 173, and the contact friction is reduced by the multiple sets of balls 173.
