The duct of tensioned prestressing bar, presstressed reinforcing steel are reserved in the concrete-filled double skin steel tube tower and cushion cap
Concrete-filled double skin steel tube tower top is started from, cushion cap cavity top is terminated in, using post-tensioned construction.
Reserving hole channel at the anchorage of the presstressed reinforcing steel configures steel pipe, realizes and makees to the local restriction of concrete
With preventing the splitting of concrete.
In the annular horizontal steel plate of cushion cap cavity top the arrangement weld stud and vertical anti-shear steel plate.
The utility model has the advantages that compared with the existing technology
(1) lower part tower be concrete structure with hollow sandwich, outer and inner tube replace distributing bar act on while from
Arrive the effect of construction mould, it is easy for construction, steel pipe thickness is effectively reduced, reduces steel using amount；

The overall performance of performance, structure is good；
(3) cap design of pile uses the principle of composite structure, and annular horizontal steel plate replaces tension reinforcement to alleviate while acting on
The stress concentration phenomenon of concrete at anchorage, vertical anti-shear steel plate instead of shear reinforcement effect, the design of cushion cap so that
It is more convenient to construct.
(4) structural system all uses assembly construction method, can significantly guarantee construction quality, improve construction efficiency, drop
Low working measure expense.
