Abstract
A kind of cone-cylindricality combination pile tube, it comprises conical pipe pile cutoff and column tube pile cutoff, and it is characterized in that the top of cone-cylindricality combination pile tube is taper pile cutoff, bottom is cylindricality pile cutoff.Technique effect of the present utility model is: pile body upper taper pile cutoff has the function of the top soil body around compacting pile body, and can improve pile body integrated carrying ability and pile foundation stability, can improve the supporting capacity of friction pile especially.Meanwhile, pyramidal structure makes pile body top loaded area increase, and the laying that can be composite foundation provides larger Area of bearing, and then improves pile foundation integrated carrying ability.
Description
Technical field
The utility model relates to civil construction field, is specifically related to a kind of cone-cylindricality combination pile tube.
Background technology
Existing cylindrical pipe pile is used in deep soft soil foundation process engineering at present, it applies relative maturity, but its anti-settling ability and stability are the key factors affecting Bearing Behavior of Pile always, therefore, in order to increase the anti-settling ability of pile tube, strengthen its stability, pile body upper part is designed to pyramidal structure, and when pile body sinks to after in soil, the top soil body around pile body can extrude more closely knit by the pyramidal structure on top, reduce the probability of pile body top sidesway, make pile body more stable; Due to the structure of upper taper, pile body upper end area is greatly increased, too increases the loaded area of pile body with this, the laying of convenient composite foundation surface layer, and increase its stability, pile foundation total bearing capacity is greatly improved.
Summary of the invention
The purpose of this utility model there are provided a kind of cone-cylindricality combination pile tube, conical pipe pile pile body bottom is designed to cylindricality pile cutoff, has both made full use of the soil body side friction of conical pipe pile side, can increase pile foundation supporting capacity again.
The utility model is achieved like this, a kind of cone-cylindricality combination pile tube, comprises conical pipe pile cutoff and column tube pile cutoff, it is characterized in that: the top of cone-cylindricality combination pile tube is taper pile cutoff, and bottom is cylindricality pile cutoff.
Preferably, the inner and outer diameter of described taper pile cutoff reduces from top to bottom gradually by certain taper, and tapered pile segment length requires according to actual design and determines.
Preferably, described cylindricality pile cutoff bottom is unified inner and outer diameter cylindrical pipe pile structure.
Technique effect of the present utility model is: in the construction period, due to the own characteristic of cone-cylindricality combination pile tube, tapering point is upper, post ends under, be conducive to the side friction and the bearing capacity that play taper pile cutoff surrounding soil, pile tube upper surface area increases simultaneously, and loaded area strengthens, and supporting capacity strengthens.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the sectional drawing of the utility model A-A conical section.
Fig. 3 is the sectional drawing of the utility model B-B cylindrical portion.
In the drawings, 1, taper pile cutoff 2, cylindricality pile cutoff.
Detailed description of the invention
As shown in Figure 1, the utility model comes work and enforcement like this, a kind of cone-cylindricality combination pile tube, the inner and outer diameter of PTC type cone-cylindricality combination pile tube tapered pile section 1 reduces from top to bottom gradually by certain taper, tapered pile segment length requires according to actual design and determines, and bottom is unified inner and outer diameter cylindrical pipe pile structure 2.Static pressure pile-sinking mode is adopted to construct.
Claims (3)
