Abstract
A kind of Bamboo-shaped threaded hole conical pipe pile, it includes conical pipe pile, Bamboo-shaped disk body, starlike threaded hole three parts, it is characterized in that conical pipe pile has Bamboo-shaped disk body from stake bottom end spacing certain distance, the reducing hole being spirally distributed is opened on tapered pile tube wall.The utility model has the technical effect that：（1）Bamboo-shaped conical pipe pile can increase effective contact area with soil around pile, increase its pile side friction, and that eliminates the slips suffered by a part of pile body embraces pressure, its bearing capacity is made to be significantly improved.（2）The maximum value of excess pore water pressure is reduced in pile body trepanning can reduce pile driving process, and then mitigates the harm caused by adjacent buildings.（3）Water easily enters in pile pile in foundation soil, when water is more in pile body tube chamber, water extraction way can be taken to be excluded, accelerate the effect of weak soil discharging consolidation, improve soil classifiction, enhances foundation bearing capacity, keep pile foundation stability more preferable, and reduces the final settlement of building.
Description
Technical field
The utility model is related to a kind of conical pipe pile more particularly to a kind of Bamboo-shaped threaded hole conical pipe piles.
Background technology
Pile pile pile-type type is various in building trade at present, meets different demands to classifying by single,
The mechanism of action of its pile foundation meets the load requirement of building again without variation, the bearing capacity of stake, and stake is held
Carry power is influenced by pile side friction and end resistance.In today that construction industry is increasingly flourishing, skyscraper is such as emerged rapidly in large numbersBamboo shoots after a spring rain
As rise sheer from level ground, emerge one after another.The requirement for bearing capacity for meeting bigger is needed, the diameter or length that can only increase stake hold to improve
Power is carried, it is corresponding to increase engineering cost and difficulty of construction and duration.Simultaneously because increase or pile body diameter that stake is long, in pile sinking
In the process, it will generate prodigious excess pore water pressure, the unfavorable dissipation of excess pore water pressure, it will influence the construction matter of engineering
Amount and progress.
Invention content
The purpose of this utility model is to provide a kind of tapered pile pile of Bamboo-shaped threaded hole, using Static piling or
The tapered pile pile of Bamboo-shaped threaded hole is sunk to deep soft soil foundation by " quiet brill is taken root in " method, gives full play to Bamboo-shaped threaded hole conical pipe
The advantage of pile bearing capacity, at the same during the pile driving process pile pile cavity polywater act on, accelerate effect of driving pile caused by it is unfavorable because
Element accelerates dissipation of excess pore-water pressure.Therefore it had not only made full use of the soil body side friction of conical pipe pile side, but also can increase pile foundation
Bearing capacity.
The utility model is achieved like this, a kind of Bamboo-shaped threaded hole conical pipe pile, it includes conical pipe pile, ring
Shape disk body, starlike threaded hole three parts, it is characterized in that conical pipe pile has Bamboo-shaped disk body from bottom end spacing h, in conical pipe pile side
One group of circular hole of three starlike distributions in equilateral triangle is opened at wall sustained height, and three holes opened then are rotated integrally into 60o
Open one group of aperture of three aperture increases 1/20d again along stake length direction spacing h afterwards, vertically-adjacent two
The small pitch of holes of group is equal, and the small aperture on same plane is identical, according to this trepanning mode, is boring from bottom to top
Several apertures being spirally distributed gradually increased variable diameters hole is provided on shape pile pile wall.
The utility model has the technical effect that：（1）Bamboo-shaped conical pipe pile can increase effective contact area with soil around pile,
Increase its side friction, its bearing capacity is made to be significantly improved.（2）The Bamboo-shaped disk body energy extrusion soil of one determining deviation is eliminated
Armful pressure of slips suffered by one point of pile body, improves the freezing tolerance of soil, while pile body is in tangential force and normal force
Stress, so that stake and the structural behaviour of soil is not fully exerted, and therefore pile body length made to be reduced, it is survivable
Pile body.（3）Stress increment and the radial displacement of the soil body in pile driving process can be reduced in pile body trepanning, excess pore water can also be reduced
The maximum value of pressure, and then mitigate effect of driving pile and endangered caused by adjacent buildings.（4）The excess pore water pressure of the soil body
It is gradually increased along depth direction, and pile body open pore size is bigger at same depth, dissipation of excess pore-water pressure is faster.In foundation soil
Water is easily accessible in pile pile, when water is relatively more in pile body hole, water extraction way can be taken to be excluded；As water level in borehole reduces,
Water can penetrate into pile pile again in soil, so that the water content of soil is further decreased, soil classifiction is improved, foundation bearing
Power enhances, and pile foundation stability is more preferable.The soil compaction effect of adjacent stake can be effectively reduced when the tapered tube pile construction of reducing Bamboo-shaped threaded hole,
It is energy saving.
Description of the drawings
Fig. 1 is the structural plan figure of the utility model, and Fig. 2 is the utility model tapered pile segment structure 1-1 floor map.
In Fig. 1,1, taper tube wall 2, Bamboo-shaped disk 3, stellate pore.
Specific implementation mode
As shown in Figure 1 and Figure 2, the utility model is achieved like this is provided with several stellate pores 3 along 1 pile lining of conical pipe pile
Helically rise.The tapered pile pile of Bamboo-shaped threaded hole of the utility model only need to use special pipe pile steel mold as required in factory
Production, method use Static piling pile sinking compared with Bamboo-shaped pile pile production technology, site operation, and other processes are compared with pipe
Pile constructing process.In static piling construction, in soil water by the tapered pile pile pile lining of Bamboo-shaped threaded hole several are two-way right
Perforation flow into pile pile cavity in, then by pump by cavity mud and water extract out, reduce pile pile surrounding aqueous amount, increase
Strong foundation bearing capacity.The gap between ring pile pile and stake holes is filled up during the pile driving process according to " quiet brill is taken root in " technology,
Ring pile pile is planted after the completion of stake and before cement mortar is fully cured, and launches rubble into the gap immediately, and set using vibrating
Standby formation rubble in fact of inserting repeatedly goes along with sb. to guard him layer, and going along with sb. to guard him layer by rubble constructs Soft Soil Consolidation drainage channel, and rubble goes along with sb. to guard him layer and bamboo
It saves pile pile and forms composite pile structure, be not only conducive to improve bearing capacity of pile foundation, but also drain conducive to Soft Soil Consolidation；Therefore it was both abundant
Using the soil body side friction of conical pipe pile side, and pile foundation bearing capacity can be increased.
