Octagonal pile and foundation structure applying octagonal pile

Abstract

The invention discloses an octagonal pile and a foundation structure applying the octagonal pile. The octagonal pile comprises a pile body, the cross section of the pile body is in an octagonal shape, reinforcing steel bars are arranged in the pile body, the length direction of the reinforcing steel bars is consistent with the direction of the pile body, and fine stone concrete is filled among the reinforcing steel bars. When applied in a pile foundation, the octagonal pile saves more materials than the traditional square piles, tubular piles, wood piles and the like, thereby benefiting of reducing construction cost. When applied in the foundation treatment, the octagonal pile is more assuring on the piling quality than deep stirring piles, bored concrete piles and the like, is more flexible and rapid in construction and greatly shortens the construction period. The octagonal pile is simple in construction and adopts hammering type piling. Piling equipment is composed of a pile hammer, a piling frame, accessory equipment (such as a pile cap, a cushion, a pile follower and the like) and the like and has obviously lower field requirement than other piling machines.

Description

technical field [0001] The invention relates to an octagonal pile; the invention also relates to a foundation structure. Background technique [0002] Traditional building materials belong to the basic raw material industry, and some products are seriously polluted, consume high resources, waste land, threaten the ecological environment, and are difficult to meet the requirements of national economic construction and modern social development. In areas with a large number of soft soils, many equipment and maintenance structures in power engineering need to be treated as foundations, and the selection of current foundation types often cannot properly meet the design requirements. , bored cast-in-place piles, powder-sprayed cast-in-place piles, and even fences all use φ400 prestressed pipe piles, which greatly increases the construction cost; while the natural foundation pressed wood piles, although the cost is lower, but its reliability and durability Poor performance, it is...

Problems solved by technology

[0002] Traditional building materials belong to the basic raw material industry. Some products produce serious pollution, consume high resources, waste land, threaten the ecological environment, and are difficult to meet the requirements of national economic construction and modern social development.

In areas where there are many soft soils, many equipment and maintenance structures in power engineering need foundation treatment, but the current foundation type selection often cannot properly meet the design requirements, often overkill and use concrete prefabricated square piles , bored cast-in-place piles, powder-sprayed cast-in-place piles, and even enclosure walls all use φ400 prestressed pipe piles, which greatly increases the construction cost; while natural foundation pressured piles, although lower in cost, are reliable and durable Poor performance, it is difficult to meet the quality requirements of the building
