Post-grouting prestressed concrete hollow pile and manufacturing method thereof
The invention relates to a post-grouting prestressed concrete hollow pile and the manufacturing method thereof. The hollow pile comprises multiple hollow pile units, a post-grouting pile tip and a pile butt grouting pipe connecting piece, wherein each hollow pile unit comprises a lower end plate, an upper end plate, a post-grouting lower connecting piece, a post-grouting upper connecting piece, a grouting pipe, a sealing washer and sealing cement. On the premise that the traditional pile foundation production and construction technology is only changed slightly, the advantages of prestressed hollow piles and the advantages of the post-grouting technology are combined effectively, original production equipment and construction equipment are fully utilized, investment is reduced, the bearing capacity of a single pile can be improved greatly, soil compaction effect is reduced, and construction efficiency is improved.
