Abstract
The invention relates to a prefabricated prestressed concrete frame inserting and connecting integrated high pile bearing platform foundation. The prefabricated prestressed concrete frame inserting and connecting integrated high pile bearing platform foundation is composed of a plurality of steel pipe piles provided with inserting and connecting grooves and studs. The river bottom or seabed mud surface and the bottom of a bearing platform are connected through a plurality of roof frame prefabricated prestressed concrete frames. The prefabricated prestressed concrete frames and the steel pipe piles are fixed between original sliding chutes through a high-strength grouting material, a curved shearing integrated space structure is formed by the independent steel pipe piles, and the upper portions of the steel pipe piles are connected into a whole through the reinforced concrete bearing platform. The prefabricated prestressed concrete frame inserting and connecting integrated high pile bearing platform foundation has the advantages that the stability is good, the overall rigidity is large, the pile body displacement and the inner force are small and the concrete frames are installed conveniently. Concrete frame cracks are small through the application of the prestress, and reinforcing steel bars in the concrete frame are good in corrosion-resisting performance.
