Concrete piles

Abstract

The present invention relates to a concrete pile, which includes: an upper part and a lower part, the diameter D of the upper part is larger than the diameter d of the lower part, wherein: the concrete pile also includes: a middle part connecting the upper part and the lower part, the middle part is the lower part, the upper part and the lower part Large inverted truncated cone, the maximum diameter of the inverted truncated cone is equal to the diameter D of the upper part, the minimum diameter of the inverted truncated cone is equal to the diameter d of the lower part, and the ratio of the diameter D of the upper part to the diameter d of the lower part is 1.2 to 8: 1. The middle part is a plurality of inverted cones arranged axially along the concrete pile, and the included angle between the extension line of the inclined surface of the middle part and the central axis of the concrete pile is 5° to 90°. The concrete pile of the present invention can ensure and improve the bearing capacity of the pile body , effectively maintain the design shape of the pile body, and can also greatly save the amount of concrete used. Under the same conditions, with the same amount of concrete materials, the bearing capacity of the pile body can be increased by more than 80%.

Description

technical field [0001] The invention relates to a concrete pile, in particular to a concrete pile with an inverted cone. Background technique [0002] With the rapid development of the construction industry, construction projects have higher and higher requirements for foundation design and construction, so concrete piles are more and more widely used in high-rise buildings, bridges, ports and offshore constructions. In order to make the pile foundation meet the requirements of anti-deformation, anti-seismic and other architectural design, methods such as lengthening the pile body and increasing the diameter of the pile body are often used to increase the bearing capacity. However, lengthening or increasing the diameter of the pile body will inevitably lead to an increase in the amount of concrete, especially when the ratio of the length to the diameter of the pile body is too large, the bearing capacity of the pile body will be significantly reduced. Therefore, by lengtheni...

However, lengthening or increasing the diameter of the pile body will inevitably lead to an increase in the amount of concrete, especially when the ratio of the length to the diameter of the pile body is too large, the bearing capacity of the pile body will be significantly reduced. Therefore, by lengthening or enlarging the pile body It is often futile to improve the bearing capacity of the pile body, and it will inevitably cause a lot of waste of concrete
