Embodiment Construction

[0014] The following are specific examples of the present invention to further describe the technical solutions of the present invention, but the present invention is not limited to these examples.

[0015] The concrete solid pile includes a reinforcement cage as a middle skeleton and a concrete entity poured on the reinforcement cage.

[0016] 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.

[0017] Concrete entities include cement, gravel, slag, sand and high-calcium fly ash, of which the proportion of high-calcium fly ash is 30% to 45%, and the calcium content in high-calcium fly ash is 10% to 15%. .

[0018] A modifier is added to the concr...

Abstract

The invention provides a concrete solid pile, belonging to the technical field of buildings. The concrete solid pile solves the problems that an existing pile body has insufficient bearing strength, poor tension stability, lack of activity and self-hardening property in raw materials, incapability of realizing multiple process regulation and control indexes in manufacturing processes and the like. The concrete solid pile comprises a steel bar cage as a middle framework and a concrete solid poured onto the steel bar cage, wherein the concrete solid comprises cement, gravel, slag, sand and high-calcium fly ash, the content by specific weight of high-calcium fly ash is 30%-45%, and the calcium content in high-calcium fly ash is 10%-15%. According to the concrete solid pile, high-calcium fly ash and a corresponding modifier are added in the traditional component formula and are subjected to specific weight adjustment again, so that multiple process regulation and control indexes can be realized in the manufacturing processes of a whole base pile, the compressive strength and tension stability of the whole base pile are effectively strengthened by utilizing the characteristics of high-calcium fly ash, and the concrete solid pile further has the characteristics of activity of volcanic ash, small fineness, small weight of screen residue 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. 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 foundation...
