121 other ends are connected to first and meet native side 111, and the second Ying Keng is when 122 other ends are connected to the first Ying Keng 112.
Based on aforementioned, distribution mode of the arrangement of reinforcement 2 in pile body 1 is specially：Nonmetallic presstressed reinforcing steel meets native side along 21 first
111 and second meet native side 121 and are alternatively arranged, and reinforcing bar 22 and nonmetallic presstressed reinforcing steel 21 meet hole along the first sides Ying Keng 112 and second
Side 122 alternates arrangement, and reinforcing bar 22 is alternatively arranged along the first construction side 123.
First meet it is native when 111 and second meet native 121 on arrangement of reinforcement use nonmetallic presstressed reinforcing steel, for enhance bending resistance and
Shear behavior, simultaneously as such muscle material has the performance of anticorrosion and acid and alkali-resistance so that pile body 1 can be applicable in more soil layers
The foundation pit of environment.
Referring to Fig. 4, furtherly, stirrup 4 is additionally provided in pile body 1, stirrup 4 is arranged perpendicular to the axial direction of pile body 1, and along stake
1 length direction of body is sequentially arranged at intervals, and the interval of arrangement of reinforcement 2 is fixed in the circumferential direction of stirrup 4 and forms muscle cage, the muscle cage with stirrup 4
Stabilized structure can ensure that structural strength on the basis of being further reduced concrete amount.
The structure of stirrup 4 is specially：Including being arranged inside and outside and in the third Ying Keng of " Ω " shape when 41 and third meet native
42 end when 41 end and third meet native 42, third Ying Keng is correspondingly connected with by the second construction side 43,1 upper and lower side of pile body
End plate 5 is equipped on face, end plate 5 is equipped with the perforation adaptable with the cross section of arrangement of reinforcement 2, and wing plate 12 is symmetrically set in annular web
The connection transition face of 11 opening both sides, wing plate 12 and annular web 11 is inclined-plane or arc surface.The shape of stirrup 4 with match
Longitudinal mode of muscle 2 is corresponding so that the two can preferably connect and facilitate the pouring molding of pile body 1.
A kind of connection structure of Ω types foundation pit supporting pile is also provided referring to Fig. 5 and Fig. 6, in the present embodiment, specially：Including
At least two Ω types foundation pit supporting piles, and the inner sleeve 6 that is connected between Ω type foundation pit supporting piles, any two Ω types
Foundation pit supporting pile is vertically connected with integrally by the cooperation of arrangement of reinforcement 2 and inner sleeve 6.
Inner sleeve 6 is hollow internal thread structure, and the arrangement of reinforcement 2 in the Ω type foundation pit supporting piles being located above is from 1 lower end of pile body
It stretches out in face and is threadedly coupled with inner sleeve 6, the arrangement of reinforcement 2 in underlying Ω types foundation pit supporting pile is stretched from 1 upper surface of pile body
Go out and be threadedly coupled with inner sleeve 6, glue is filled between arrangement of reinforcement 2 and inner sleeve 6.
The junction of any two Ω type foundation pit supporting piles is also enclosed equipped with outer sleeve 7, and the height of outer sleeve 7 is more than pile body 1
Between clearance distance, the structure of outer sleeve 7 is specially：Meet a hole coaming plate and Ge Ying fortifield village plate including one, meet hole coaming plate and
The cross section for meeting fortifield village's plate is in " Ω " shape being adapted with 1 cross section of pile body, meets hole coaming plate and meets fortifield village's plate along its length two
Corresponding skirtboard is extended in side, and skirtboard is equipped with bolt hole, meets hole coaming plate by the cooperation of bolt and bolt hole and meets fortifield village
Plate is fixedly connected.
Using such structure, the mechanical property for reinforcing 1 junction of upper and lower pile body, outer sleeve 7 is assembly type, can be with
The junction of the two, easy for construction, sound construction are directly disposed around from 1 side of upper and lower pile body.
If foundation pit is deeper in support engineering, single stake position can be used more support piles invented at all and is vertically connected with,
Preformed patterns are similarly, the pile body that is vertically connected with is needed by foundation depth selection, connection structure through the invention obtains pair
The connection pile body answered.Two connecting pins of inner sleeve 6 are threadedly coupled with the arrangement of reinforcement of upper and lower pile body 1, thus by upper and lower two pile bodies 1
Link together, in addition, two arrangements of reinforcement up and down being connected in the same inner sleeve 6 can be different materials, you can with for
Nonmetallic presstressed reinforcing steel and/or reinforcing bar；Glue in this implementation is preferably epoxide resin type glue, is filled again after threaded connection
Glue so that connection is even closer.In work progress, first upper and lower arrangement of reinforcement 2 is threadedly coupled with inner sleeve 6, but do not offseted mutually, so
Encapsulating afterwards continues after encapsulating 10s to rotate inner sleeve and continues to tighten the arrangement of reinforcement of upper and lower pile body 1, until offset can not be after for upper and lower arrangement of reinforcement 2
It is continuous to be screwed into, 1.2 times higher than muscle body tensile strength itself can be reached.
In addition, can also be preferably in the present embodiment：The spacing formed after upper and lower two pile bodies 1 connection is equal to inner sleeve 6
Highly so that inner sleeve 6 can resist pile body 1 up and down.
Embodiment 2
The present embodiment difference from example 1 is that arrangement of reinforcement 2 distribution, specially：Reinforcing bar 22 and nonmetallic presstressed reinforcing steel
21 along first meet it is native 121 alternate arrangement when 111 and second meet native, reinforcing bar 22 is along the first Ying Keng in 112, the second Ying Keng
122 and first construction side 123 be alternatively arranged.The support pile of the present invention can be shortened the construction period applied in the foundation pit of 300m*300m
40 ~ 50 days, 12000 cubes of concrete amount is saved, in the case of arrangement of reinforcement dosage is identical, can be saved relative to full reinforcement constitution
About 400,000 yuan of arrangement of reinforcement expense.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, although with reference to aforementioned reality
