Abstract
The utility model relates to a deformed sectional bored concrete pile which is poured to form by a steel bar cage and concrete. The utility model is characterized in that the cross section of the bored concrete pile is a deformed shape which can be a corner broken off rectangle, a long circle, an egg circle, an ellipse, a trapezoid, a T shape or an H shape. The utility model has the advantages that the rigidity of the deformed sectional bored concrete pile is increased when compared with the existing piles whose cross sections are circular, which is especially favorable to bending resistance. The cross section which is a trapezoid, a T shape or an H shape is also favorable to antiseep, suitable to be the enclosure piles of deep foundation pits. Simultaneously, the deformed sectional bored concrete pile can reduce a large amount of steel bars and save cost in construction.
Description
The utility model belongs to the cast-in-place concrete pile of the pilework in the Foundation Design, particularly section.
At present, the cast-in-place concrete pile that is adopted in the construction work foundation construction is divided into two kinds of tube-sinking cast-in-situ pile and digging hole filling piles.Tube-sinking cast-in-situ pile is that the stake pipe is squeezed in the stratum, then descending reinforcing cage, concrete perfusion tube drawing pile in pipe; Digging hole filling pile is to dig out earlier a hole in the stratum, concrete perfusion retaining wall then, descending reinforcing cage, concrete perfusion pile.It is circular that the section of these two kinds of castinplace piles mostly is.Present stage, some piles often had multi-storey basement along with the development of industry with civilian construction.Its excavation construction requires the foundation ditch periphery is gone along with sb. to guard him.The concrete stake is the most frequently used in recent years fender member.The common engineering stake is a pressurized, and simple circle or square cross-section stake can be suitable for.But fender post is bent, and in order to improve pile body rigidity and to improve stress condition, circle and square cross-section stake are just not really suitable.
The purpose of this utility model overcomes the shortcoming of circular cross section castinplace pile, and a kind of section castinplace pile is provided, to improve the single pile bending resistance.
The technical solution of the utility model is such: a kind of section castinplace pile, be shaped by reinforcing cage and concrete spouting, and the section that it is characterized in that castinplace pile is special-shaped.
The utility model has the advantages that: the castinplace pile of section and existing circular cross section stake specific stiffness mutually strengthen greatly, the single pile bending resistance is improved significantly, wherein trapezoidal, T font, H-shape cross section stake also help antiseepage, are applicable to the fender post as deep foundation ditch.Can reduce a large amount of reinforcing bars during anti-same moment of flexure, reduce cost.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is that section is the stake schematic cross-section of arrisdefect rectangle.
Fig. 2 is that section is oblong stake schematic cross-section.
Fig. 3 is that section is ovate stake schematic cross-section.
Fig. 4 is that section is oval-shaped stake schematic cross-section.
Fig. 5 is that section is trapezoidal stake schematic cross-section.
Fig. 6 is that section is the stake schematic cross-section of T font.
Fig. 7 is that section is I-shaped stake schematic cross-section.
Embodiment 1 is that the cross section of this section castinplace pile is the arrisdefect rectangle, as shown in Figure 1.
Embodiment 2 is that the cross section of this section castinplace pile is a Long Circle, as shown in Figure 2.
Embodiment 3 is that the cross section of this section castinplace pile is an oval, as shown in Figure 3.
Embodiment 4 is that the cross section of this section castinplace pile is ellipse, as shown in Figure 4.
Embodiment 5 is that the cross section of this section castinplace pile is trapezoidal, as shown in Figure 5.
Embodiment 6 is that the cross section of this section castinplace pile is the T font, as shown in Figure 6.
Embodiment 7 is that the cross section of this section castinplace pile is I-shaped, as shown in Figure 7.
This section castinplace pile generally adopts tube immersing and drilling perfusion pile.Earlier the similar shape stake pipe that two ends is not sealed with the static pressure vibrator sunk pile machine of being with vibrating hammer is squeezed in the stratum, then with artificial or mechanical method from managing interior shoveling.Minimum headroom: L in pipe during borehole
2=700mm, L
3=0～L
2, stake pipe size L
