AI Technical Summary
The existing precast piles are not stable enough, especially the cylindrical precast piles, which are not well fixed in the soil.
The design incorporates tapered precast piles with a tapered structure and friction elements, such as grooves or protrusions, on the outer wall to increase friction and contact area with the soil. The pile body and pile head are connected by connecting bars and sleeves, and resin adhesive is used to enhance the stability of the connection.
This increases the friction and contact area between the precast pile and the soil layer, thereby significantly enhancing the stability and connection strength of the precast pile.
