Abstract
The invention discloses an enhanced solid preformed pile structure and a method for connecting and fixing the enhanced solid preformed pile structure and a foundation. Connecting holes are formed in the end, connected with a foundation, of a pile body, and reinforcing steel bars are pre-embedded at the peripheries of the connecting holes, so that a preformed pile can be effectively connected with the foundation on the basis that the pile is not broken. The connection strength can be controlled through regulating the pre-embedding length and number of the reinforcing steel bars, so that the construction requirement of any engineering is met. In addition, a preformed pile is of a variable-section structure, and different pile body sections are adopted, so that the friction force between the pile body and a soil body can be greatly increased, and the vertical pulling resistance of the pile body is improved.
