Concrete solid pile body

Abstract

The invention provides a concrete solid pile body, belongs to the technical field of building, and solves the problems of conventional pile bodies all have insufficient bearing strength and poor tension stability, and raw materials are lack of activity and self-hardening property. The concrete solid pile body comprises a steel reinforcement cage as a central skeleton and a concrete entity poured in the steel reinforcement cage; the concrete entity comprises cement, gravels, slag, sand, high-calcium fly ash and low-calcium fly ash, the content proportion of the high-calcium fly ash is 25%-40%, the calcium content in the high-calcium fly ash is 10%-15%, the content proportion of the low-calcium fly ash is 10%-40% that of the high-calcium fly ash, and the calcium content in the low-calcium fly ash is 1%-5%. In a whole base pile manufacturing process, a number of process control indexes can be achieved, and the compressive strength and the tension stability of base piles are enhanced with utilization of characteristics of the high-calcium fly ash; and with utilization of the ability of the low-calcium fly ash to inhibit AAR, the concrete harm caused by an alkali aggregate reaction can be eliminated.

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 body. 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 found...

Problems solved by technology

However, in the prior art, the composition and combination proportion of the raw materials of the concrete in the pile body make the overall piles formed have insufficient bearing strength, poor tension stability, and the raw materials lack activity and self-hardening, and the concrete cannot be eliminated. Due to the hazards caused by the alkali-aggregate reaction, it is still impossible to realize the process control indicators of many manufacturing processes
