Abstract
The invention discloses a kind of civil engineering pile structures, including pile hole and the pile body being located in pile hole, the hole wall internal rising in the pile hole has several inclined holes extended toward direction obliquely downward, it is equipped with metal bar in the inclined hole, is cast with concrete in inclined hole, the metal bar is connect with pile body, the injection stem along its length on the pile body, the stem does not penetrate through on pile body, is equidistantly provided with steel tendon in the circumferential direction of the pile body, and the pile body is fettered.The present invention can increase the lower end effective diameter of pile, while also seldom to the increase of cost；Meanwhile steel tendon is equidistantly provided in the circumferential direction of pile body, the pile body load-carrying ability of formation is greatly improved, and has easy for construction, easy to operate, low in cost, consolidation effect is good, and durability is good, the characteristics of materials are convenient, have a wide range of application, good in economic efficiency, function admirable.
Description
Technical field
The present invention relates to technical field of civil engineering, specially a kind of civil engineering pile structure.
Background technique
Existing pile structure, when being shaken, it is easy to be uprooped.This problem in order to prevent, it is existing to set
Meter often deepens the length of embedment of pile body, or by the enlarged-diameter of pile body, but such design is often greatly
Increase cost.Also, concrete stake by cement with soil is equal proportionally mixes, then elder generation's aperture in stake is layered in stake holes and fills out
Material compacting pile.Since the pile strength of materials is not high, so its load being able to bear is limited, when the length of pile reaches certain
It when limit, is even further continued for lengthening, can not also improve load-carrying ability again.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of civil engineering pile structure
Problem.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of civil engineering pile structure, packet
The pile body for including pile hole and being located in pile hole, the hole wall internal rising in the pile hole have several toward the oblique of the extension of direction obliquely downward
Hole, the inclined hole is interior to be equipped with metal bar, is cast with concrete in inclined hole, the metal bar is connect with pile body, in the pile
Injection stem, the stem do not penetrate through on pile body along its length on body, equidistantly set in the circumferential direction of the pile body
It is equipped with steel tendon, the pile body is fettered.
Further, the metal bar is equipped at least two spaced fixed rings.
Further, the fixed ring is equipped with several through-holes.
Further, the tension stress of the steel tendon is the 30% of the ultimate tensile strength of steel wire used.
Further, the intensity of the steel tendon is 1000MPa or more, perimeter of section 10cm or more.
Compared with prior art, the beneficial effects obtained by the present invention are as follows being: hole wall internal rising of the present invention in pile hole has
Several inclined holes extended toward direction obliquely downward, inclined hole is interior to be equipped with metal bar, and concrete is cast in inclined hole, and metal bar and pile body connect
It connects, such structure can increase the lower end effective diameter of pile, while also seldom to the increase of cost；Meanwhile in pile
Steel tendon is equidistantly provided in the circumferential direction of body, the pile body load-carrying ability of formation is greatly improved, have it is easy for construction,
Easy to operate, low in cost, consolidation effect is good, and durability is good, and materials are convenient, has a wide range of application, good in economic efficiency, function admirable
The characteristics of.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is overall structure diagram of the invention；
Fig. 2 is the structural schematic diagram of pile body in the present invention.
In figure: 1, pile body, 2, inclined hole, 3, metal bar, 4, stem, 5, steel tendon, 31, fixed ring.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2:
A kind of civil engineering pile structure, including pile hole and the pile body 1 that is located in pile hole, the pile hole
Hole wall internal rising has several inclined holes 2 extended toward direction obliquely downward, and metal bar 3 is equipped in the inclined hole 2, is cast in inclined hole 2 mixed
Solidifying soil, the metal bar 3 are connect with pile body 1, and the metal bar 3 is equipped at least two spaced fixed rings 31, just
It is fixed in inclined hole 2 in by metal bar 3, the fixed ring 31 is equipped with several through-holes, convenient for concrete is poured into inclined hole 2
Space between bottom and two fixed rings 31.Such structure can increase the lower end effective diameter of pile, at the same at
This increase is also seldom.Injection stem 4, the stem 4 do not pass through on pile body 1 along its length on the pile body 1
It is logical, about it is through to 2/3 extension position of pile body 1, the circumferential upper spaced set steel tendon 5 of pile body 1, by 1 beam of pile body
It ties up, the tension stress of the steel tendon 5 is the 30% of the ultimate tensile strength of steel wire used, and the intensity of the steel tendon 5 is
The steel tendon of 20 Φ 5.0 may be selected in 1000MPa or more, perimeter of section 10cm or more.Using after this structure, since stem 4 exists
In pile body 1, along with the restraining force of steel tendon 5,40% or so, and whole device structure letter is can be improved in the bearing capacity of single pile
Single, material source is extensive, and construction and preparation are all very convenient.
Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention,
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features.
All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention
Within protection scope.
