The invention provides a concrete
solid pile structure and belongs to the technical field of buildings. The problem that the conventional
pile body is poor in bearing strength and low in tension stability and does not have heat insulation, sound absorption,
flame retardant property and other properties is solved. The concrete
solid pile structure comprises a steel reinforcement cage serving as a middle framework and a concrete
solid body poured onto the steel reinforcement cage, wherein the concrete
solid body comprises
cement, gravel,
slag, sand, high-
calcium fly ash and low-
calcium fly ash; a
fiber plasterboard is attached to the outer wall of the concrete
solid body; and a ratio of
waste paper fibers to
gypsum in the
fiber plasterboard is 15:85-18:82. According to the concrete solid pile structure disclosed by the invention, multiple
process control indexes can be realized in the whole foundation pile manufacturing process, and the
compressive strength and tension stability of the foundation pile are enhanced by utilizing the characteristics of the high-
calcium fly ash; the capacity of AAR is inhibited by utilizing the low-calcium fly ash, and damage of concrete, caused by an alkali-aggregate reaction, can be eliminated; and moreover, according to use of the surface
fiber plasterboard, the concrete solid pile structure has the characteristics of heat insulation, sound absorption,
flame retardant property, moth resistance,
water resistance,
moisture resistance and the like.
