The invention provides a steel-
solid waste concrete combined bearing platform with a
composite structure and a construction method thereof. According to the steel-
solid waste concrete combined bearing platform with the
composite structure and the construction method thereof, six
steel plates are adopted to form a closed box body, so that the tensile strength and the
crack resistance of the outermost layer of the bearing platform are improved, and the
bearing capacity and the rigidity of the bearing platform are greatly improved; a shear-resistant truss is arranged between a column foot and a
pile body, and effective transmission of concentrated loads is achieved through the multiple pieces of profile steel arranged in the inclined direction; and stress coordination trusses are arranged between the adjacent concrete-filled
steel tube piles to enhance the overall coordination between the concrete-filled
steel tube piles, the shear-resistant trusses and the stress coordination trusses greatly increase the
interface bonding degree of the steel tubes and the bearing platform, reinforcing connecting plates are arranged at the joints of the steel tubes and the
steel plates to increase the connecting degree of the steel tubes and the
steel plates, and the integrity of the whole combined bearing platform is greatly improved.
Solid waste concrete with the
solid waste replacement rate lower than 30% is adopted in the bearing platform box body, the
adverse effect caused by shrinkage of
mass concrete can be relieved, and the demonstration effect on
engineering application and popularization of the solid waste concrete is achieved.
