Composite-reinforcement partially-prestressed concrete solid square pile and production method thereof
The invention relates to a composite-reinforcement partially-prestressed concrete solid square pile comprising a concrete pile body. The concrete pile body is connected with a concrete pile tip; a reinforcement cage is arranged within the concrete pile body and comprises non-prestressed main bars, prestressed main bars and hoops; the non-prestressed main bars and the prestressed main bars are hooped with square spiral bars to form the reinforcement cage; the ends, close to the concrete pile tip, of the four non-prestressed main bars at four corners of a square are bent to the center and extended into the concrete pile tip, forming a concrete pile tip anchor bar; a concrete pile tip central reinforcing bar is arranged within the concrete pile tip; the lower end of the concrete pile tip central reinforcing bar is welded to the lower end of the concrete pile tip anchor bar. The composite-reinforcement partially-prestressed concrete solid square pile is good in corrosion resistance, good in deformability, excellent in mechanical property, good in shock resistance and high in capacity of entering rock.
