Bougainvillea speetabilis flower-shaped concrete pile

Abstract

The invention provides a bougainvillea speetabilis flower-shaped concrete pile. The bougainvillea speetabilis flower-shaped concrete pile comprises two pile caps and a pile body; the pile body or each pile cap comprises three convex wings and three concave wings; the edges of the convex wings and the concave wings are convex arcs and concave arcs correspondingly; the adjacent convex wing and concave wing are in streamline connection; the pile body comprises six main reinforcements and concrete; the six main reinforcements consist of three vertex main reinforcements and three midpoint main reinforcements; the three vertex main reinforcements are positioned on a symmetrical shaft of the three convex wings and are positioned at the three vertexes of a first regular triangle; the three midpoint main reinforcements are positioned at the midpoints of three edges of the first regular triangle; the main reinforcements are hooped by multiple bundles of reinforcements, and the main reinforcements and the multiple bundles of reinforcements form a steel reinforcement cage; the steel reinforcement cage is coated with concrete; three through reinforcements are positioned at three vertexes of a second regular triangle; the second regular triangle is positioned on the inner side of the first regular triangle; and the three through reinforcements are connected with the two pile caps. The bougainvillea speetabilis flower-shaped concrete pile has the following beneficial effects: the through reinforcements and end plates are welded, so that the integrity of the pile can be effectively improved; and a bougainvillea speetabilis flower shape with larger perimeter-to-area ratio is adopted, so that the bearing capacity of the pile body and the utilization rate of the materials can be increased.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a quincunx-shaped concrete pile. Background technique [0002] Pile foundation engineering is widely used in construction, transportation, transmission and transformation line towers, and marine foundations due to its fast construction speed, large reinforcement depth, suitable for various geological conditions, and can significantly increase the bearing capacity of the foundation and reduce deformation. . Increasing the pile diameter or pile length can improve the overall bearing capacity of the pile foundation, but blindly increasing the material to increase the bearing capacity is not economical and increases the difficulty of construction. Therefore, it is necessary to seek a high utilization rate of unit materials to achieve high bearing capacity and low cost. , and the stability of the foundation can significantly increase the new type of pile foundation, which has be...

Problems solved by technology

After investigation, the main cross-section forms of prefabricated reinforced concrete piles on the market are circular and square. The specific surface area of ​​circular piles and square piles is relatively small, the material utilization rate is relatively low, and the performance of materials is not fully utilized. Therefore, through It is important to change the cross-sectional shape of the pile to increase the bearing capacity of the pile foundation
