Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of construction, and relates to a foundation pile for construction, in particular to a concrete solid pile structure. Background technique

[0002] Foundation pile is a professional term in building structure, and its associated terms include pile foundation, pile group foundation and single pile foundation. Pile foundation: A foundation composed of piles and caps connected to the top of the piles. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Single pile foundation: refers to an independent foundation using a single pile (usually a large diameter pile) to bear and transmit the load of the superstructure (usually a column). Pile group foundation: refers to a pile ...

Examples

Embodiment Construction

[0018] The following are specific examples of the present invention to further describe the technical solution of the present invention, but the present invention is not limited to these examples.

[0019] The concrete solid pile structure includes a reinforcement cage as a middle skeleton and a concrete entity poured on the reinforcement cage.

[0020] The cross section of the reinforcement cage is a regular polygon, and each side of the regular polygon is an arc side. The shape of the reinforcement cage is conducive to the uniform bearing capacity of the overall foundation pile, and improves the compressive strength. It also has the characteristics of simple and easy manufacturing process and solid and stable skeleton structure.

[0021] Concrete entities include cement, gravel, slag, sand and high-calcium fly ash, in which the proportion of high-calcium fly ash is 25% to 40%, and the calcium content in high-calcium fly ash is 10% to 15%. The content of low-calcium fly ash ...
