Had the following advantages that compared with prior art according to a kind of inverted T-shaped prestressing force binodal support pile provided by the invention：
1st, declined to a great extent using prestress wire as cage bar, support pile steel using amount, cost reduces.
2nd, docked using reverse joint near inflection point, change single-unit stake facilitates transport, lifting into binodal stake, and can
It is greatly reduced to meet to transport, the distributing bar of lifting requirements, reverse pile extension can make the arrangement of reinforcement and moment of flexure envelope of support pile in addition
Figure matches, and pile body only needs one side arrangement of reinforcement, and with regard to that can meet bending resistance requirement, amount of reinforcement is greatly reduced.
3rd, using shaped steel built-in fitting pile extension, pile extension is convenient, and joint dimension can be made accurate, and stress performance is good.
4th, Curved steel bar is configured in pile body, the shear behavior and globality of pile body can be greatly improved.
5th, the degree of prestressing of support pile can be greatly improved using the inverted T-shaped stake with the edge of a wing, makes pile body not work with cracking, from
And the bending rigidity of stake is greatly improved, reduce deformation.
6th, soil crowning appearance is easily formed using the inverted T-shaped stake with the edge of a wing, being especially combined with mixing pile can effectively anti-leak-stopping soil
And soil pressure is transmitted, pilespacing can be expanded, the advantage for making inverted T-shaped stake bending strength big is not fully exerted, so as to effectively reduce branch
Protection structure cost.
