Problems solved by technology

[0002] With the popularization of prefabricated pile foundations, PHC pipe piles and PRHC pipe piles are mainly used in projects at present. PHC is equipped with prestressed steel rods, and PRHC is equipped with prestressed steel rods and steel bars. Concrete above C60 is generally used. Pile breakage occurs on site during construction. Many, and because of the low torsional strength, it is impossible to cut the soil by torsion
At the same time, the cost of steel pipe piles used in engineering is high, the corrosion resistance is poor, and the waste of steel structures is serious

Embodiment

[0014] Example: such as figure 1 As shown, the main body of the corrugated thin steel plate-concrete composite hollow section pipe pile in this embodiment includes a corrugated thin steel plate 1, inner concrete 2 and outer concrete 3, and the combination of the three forms a pipe pile.

[0015] Such as figure 1 As shown, the corrugated thin steel plate 1 encloses a closed space, the inner concrete 2 is located inside the corrugated thin steel plate 1 , and the outer concrete 3 is located outside the corrugated thin steel plate 1 . A number of openings are provided on the corrugated thin steel plate 1, through which the inner concrete 2 and the outer concrete 3 are connected and the inner concrete 2 and the outer concrete 3 are integrated. At this time, the corrugated thin steel plate 1 is equivalent to being embedded in the concrete of the pipe pile; in this way, the corrugated thin steel plate 1 can increase the torsional and flexural strength of the pipe pile section, so t...

Abstract

The invention relates to the technical fields of the design and the building of engineering structures, and particularly relates to a wavy thin steel plate-concrete combined hollow-section tubular pile and a manufacturing method thereof. The wavy thin steel plate-concrete combined hollow-section tubular pile is characterized by consisting of a wavy thin steel plate and concrete, wherein the wavy thin steel plate defines a closed area; the concrete wraps the inner and outer sides of the wavy thin steel plate; further, the concrete located on the inner and outer sides runs through holes formed in the wavy thin steel plate to form a whole. The wavy thin steel plate-concrete combined hollow-section tubular pile has the advantages that, through coating the external side of the wavy thin steep plate with the concrete, the torsion strength and the bending strength of the section of the tube pile are greatly enhanced; due to the enhancement of the torsion strength, cutting a soil body by the tube pile through torsion to sink the pile becomes possible; such a rectangular hollow section still has a larger space to be popularized to the structures of a bridge pier column, industrial and civilconstruction and the like; and compared with a steel tube pile applied to a project, the wavy thin steel plate-concrete combined hollow-section tubular pile has the advantages that cost is greatly decreased, corrosion-resistant performance is obviously enhanced, and durability is improved.

Description

technical field [0001] The invention relates to the technical field of engineering structure design and construction, in particular to a corrugated thin steel plate-concrete composite hollow section pipe pile and a manufacturing method thereof. Background technique [0002] With the popularization of prefabricated pile foundations, PHC pipe piles and PRHC pipe piles are mainly used in projects at present. PHC is equipped with prestressed steel rods, and PRHC is equipped with prestressed steel rods and steel bars. Concrete above C60 is generally used. Pile breakage occurs on site during construction. There are many, and because of the low torsional strength, it is impossible to cut the soil by torsion. At the same time, the cost of steel pipe piles used in engineering is high, the corrosion resistance is poor, and the waste of steel structures is serious. Contents of the invention [0003] The object of the present invention is to provide a corrugated thin steel plate-conc...
