Abstract

The invention discloses a large-diameter strong composite pile which comprises a middle pile core, wherein the periphery of the middle pile core is provided with a peripheral pile; the diameter of the middle pile core is 300-600mm, the diameter of the peripheral pile is 650-1000mm; and the peripheral pile is a cement powder spraying pile. The large-diameter strong composite pile has the advantages of being reasonable in structure, convenient in construction and good in reinforcement.

Description

Major diameter stiffness composite pile
Technical field
The present invention relates to a kind of stiffness composite pile.
Background technology
Existing composite pile, the stake core diameter is all less than 30cm, and periphery stake diameter is all less than 60cm, a little less than the reinforcement performance, needs that can not the well adapted highrise building.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, easy construction, the major diameter stiffness composite pile that reinforcement performance is good.
Technical solution of the present invention is:
A kind of major diameter stiffness composite pile is characterized in that: comprise the central pile core, peripheral stake is set in the periphery of central pile core; The diameter of said central pile core is 300 ~ 600mm, and the diameter of outer skirt piles is 650 ~ 1000mm; The Investigation of Cement Powder Spray stake of outer skirt piles position.
The central pile core is long conveyor screw stake or the stake of compacting body.
The job practices of described major diameter stiffness composite pile is characterized in that: the stake of first injection Investigation of Cement Powder Spray, the core of injection central pile then.
The job practices of described major diameter stiffness composite pile is characterized in that: first injection central pile core, the stake of injection Investigation of Cement Powder Spray then.
The present invention is rational in infrastructure, easy construction, and reinforcement performance is good.Powder spray piling is than the cement earth pile steady quality of other types; More obviously ' after the central pile core was squeezed into, its squeezed enhancement effect was remarkable, has two-way reinforcement effect for the reinforcement of soft soil effect high to water content; Bond enhancing promptly to the compacted enhancing of pile peripheral earth, and to rigid pile.The range of application of major diameter complex is big, can be widely used in pile foundation, composite foundation and the deep foundation pit support of highrise building, and supporting capacity significantly improves.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Fig. 1 is the structural representation of one embodiment of the invention.
The specific embodiment
A kind of major diameter stiffness composite pile comprises central pile core 1, and peripheral stake 2 is set in the periphery of central pile core; The diameter of said central pile core is 300 ~ 600mm, and the diameter of outer skirt piles is 650 ~ 1000mm; The Investigation of Cement Powder Spray stake of outer skirt piles position.
The central pile core is long conveyor screw stake or the stake of compacting body.
During construction, the stake of first injection Investigation of Cement Powder Spray, the core of injection central pile then.
When perhaps constructing, first injection central pile core, the stake of injection Investigation of Cement Powder Spray then.
