Problems solved by technology

[0007] In this case, the existing foundation pile technology must adopt additional technical means to perform a technical treatment on the unfavorable geological layer under the surface to meet the requirements of becoming a bearing layer, or increase the number of foundation piles, otherwise it will not be able to meet the load bearing requirements at the same time. Design requirements for force and shear resistance

Embodiment Construction

[0026] Such as figure 1 As shown, in an embodiment of the quincunx reinforced pipe pile 1 of the present invention, the pile body 11 is included, and the pile body 11 is a quincunx-shaped prefabricated concrete part composed of six semicircular arcs 12, and a reinforcing cage (in the figure) is arranged inside not shown).

[0027] The outer surface of each side of the pile body 11 is provided with semicircular arcs 12, so six semicircular arcs 12 are arranged on the outer surface, which increases the pile side friction of the pipe pile.

[0028] The present invention also increases the bearing capacity of the pile end of the pipe pile due to the arrangement of the above-mentioned semicircular arc 12 .

[0029] Further, connector structures 13 are fixedly connected to both ends of the pile body 11 . The connector structure 13 is a steel structure, on which four steel bar installation holes 132 and four tightening screw holes 131 are opened at intervals.

Abstract

The invention discloses a quincunx-shaped reinforced pipe pile, which at least comprises a pile body and is characterized in that the cross section of the pile body is quincunx-shaped. The invention additionally discloses a fabrication method of the quincunx-shaped reinforced pipe pile. Since the design of a semicircular quincunx-shaped structure is adopted, the exterior shape of the pipe pile is improved, the friction coefficient of the exterior surface is increased and the pile side friction of the pipe pile is improved. Moreover, also since the design of the semicircular quincunx-shaped structure is adopted, the end area of the pipe pile is increased and the pile end bearing capacity of the pipe pile is improved. Therefore, the quincunx-shaped reinforced pipe pile disclosed by the invention has the advantages of a circular pipe and a square pipe, overcomes the inherent defects of the circular pipe and the square pipe at the same time, has higher anti-pressing friction, higher anti-shearing performance and a higher anti-pulling ability, and makes an obvious progress and a beneficial effect.

Description

technical field [0001] The invention relates to the technical field of foundation piles, in particular to a plum blossom reinforced pipe pile used as a building foundation. The invention also relates to a processing method of the pipe pile. Background technique [0002] For the construction of a high-rise building, its structural safety depends to a large extent on the foundation design, and the foundation design is carried out in accordance with the design specifications based on geological survey parameters. When building various buildings in areas with poor soil quality, especially high-rise buildings, heavy factory buildings and structures with special requirements, foundation pile technology has become a widely used foundation form. The foundation pile technology mainly uses mechanical equipment such as a static pile driver to drive multiple prefabricated pipe piles into the ground according to the designed layout as the foundation of the building. [0003] Wherein, t...
