Abstract
The invention belongs to the field of underground engineering construction and particularly relates to an X-shaped anti-floating uplift pile, characterized by comprising a pile body; the pile body is cylindrical, the pile body extends out to form a first cone and a second cone, the cones use the pile body as a rotational axis and are bottomless, the first cone is positioned above the second cone, vertexes of the cones are connected together, and planes of the first cone and second cone along the axis of the pile body are sections that are X-shaped after being sectioned. Bearing area of the pile is enlarged and is greater than 50% as high as a traditional pile with same section, more load may be borne, and total manufacture cost is thereby reduced; anti-floating area of the pile is enlarged, and floating of the pile is inhibited effectively; bearing area is enlarged, thereby effectively reducing length and sectional area of the pile.
Description
Technical field
The invention belongs to underground engineering construction field, particularly relate to a kind of X-type uplift pile.
Background technology
In China groundwater level region, particularly construct underground engineering in the saturated soft soil layer or silt thicker soil stratum of phreatic high all must use piling way to carry out consolidation process because being difficult to large area to carry out depths reason, but all must solve pilework and float and Carrying Capacity.
Pile foundation technology is varied, use cement mixing method, sand-gravel pile, timber in early days more, it is rarely employed at present, one is that the control management specialty such as the cement mixing method ratio of mud, defeated slurry amount and stirring number of times do not perfect, equipment is outmoded, backward in technique, there is mixing uniformity difference and pile quality instability problem；Two be sand-gravel pile in order to reinforce deeper silt soft soil foundation, long in time limit owing to existing, the problems such as post-construction deformation is big, be no longer serve as the building foundation treatment that requires of deformation；Three is that civil buildings have disabled timber basis.
Silt thicker soil basement process can also use bored concrete pile, beat bored concrete pile to hard stratum, make plummer, bored concrete pile has driven cast-in-place pile and Slurry drilled pile, but two kinds of method bored concrete piles there is also some technical barriers, and one is that driven cast-in-place pile exists pile body integrity problem in Deep Thick Soft Ground；Two is that Slurry drilled pile exists mud contamination problem, pile concrete pouring quality, pile bottom sediment cleaning and supporting course judge to be difficult to the problems such as monitoring, are susceptible to bored concrete pile foundation civil buildings differential settlement, cause wall body slit event, be owing to construction existing above-mentioned technical problem and causes.
Therefore, it is necessary to develop a kind of novel pile body structure, solve the problems referred to above.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides the X-type uplift pile of the anti-lift function area of a kind of loaded area expanding stake and stake.
The technical solution adopted in the present invention is:
A kind of X-type uplift pile, it is characterized in that, including pile body, described pile body is cylindrical, described pile body extends outside pile body and is formed with pile body as rotary shaft and without the first cone of bottom surface, the second cone, described first cone is positioned at the top of the second cone and the drift angle both it connects, described first cone, the second cone along place, pile body axis plane for cut open show face after cutting open in X-shaped.
Described first cone, the second cone size are identical.
Described first cone, the second cone are positioned at the top of described pile body.
Described first cone, the second cone are positioned at the middle part of described pile body.
Described first cone, the second cone are positioned at the bottom of described pile body.
The invention have the benefit that
1, the present invention expands the loaded area of stake, compares more traditional same cross section stake, and loaded area can increase by more than 50%, can carry more heavy load, thus reduce overall cost；
2, the present invention expands the anti-lift function area of stake, the lowest floating inhibiting stake；
3, invention increases loaded area, efficiently reduce length and the sectional area of stake.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
In figure, 1-pile body, 2-the first cone, 3-the second cone, 4-cylindrical hole, 5-bellmouth, 6-bellmouth, 7-ground.
Embodiment 1
As Figure 1-3, a kind of X-type uplift pile, including pile body 1, pile body 1 is cylindrical, pile body 1 extends outside pile body 1 and is formed with pile body 1 as rotary shaft and without first cone the 2, second cone 3 of bottom surface, first cone 2 is positioned at the top of the second cone 3 and the drift angle both it connects, first cone the 2, second cone 3 along place, pile body 1 axis plane for cut open show face after cutting open in X-shaped.
First cone the 2, second cone 3 size is identical.
First cone the 2, second cone 3 is positioned at the bottom of pile body 1.
As shown in figs. 4-7, Specific construction technique is as follows: (1) sequence of construction makes cylindrical hole 4 according to rotary churning pile technique；(2) in pile foundation near bottom, rig stretches out oblique churning driven, makes bellmouth 5；(3) rig up carries certain distance, stretches out reverse churning driven arm, again carries out making bellmouth 6；(4) one bottom sectional of formation is the stake holes of " X "；(5) descending reinforcing cage casting concrete becomes pile body 1.
