The present invention is described in further detail below by specific embodiment combination attached drawing.Wherein different embodiments
Middle similar component employs associated similar element numbers.In the following embodiments, many datail descriptions be in order to
The application is better understood.However, those skilled in the art can be without lifting an eyebrow recognize, which part feature
It is dispensed or can be substituted by other elements, material, method in varied situations.In some cases, this Shen
Please it is relevant some operation there is no in the description show or describe, this is the core in order to avoid the application by mistake
More descriptions are flooded, and to those skilled in the art, these relevant operations, which are described in detail, not to be necessary, they
The general technology knowledge of description and this field in specification can completely understand relevant operation.
It is herein component institute serialization number itself, such as " first ", " second " etc., is only used for distinguishing described object,

It is indirectly connected with（Connection）.
- 4 are please referred to Fig.1,
Built pile, including concrete cover 1, steel pipe 2 and armored concrete obturator 3, concrete cover 1 pour in
2 outside of steel pipe, armored concrete obturator 3 are filled in steel pipe 2；2 outside of steel pipe is equipped with ribbed stiffener 21, and 2 inside of steel pipe is equipped with
The convex block 22 of steel pipe inner surface is protruded from, ribbed stiffener 21 sets up one section for every 90 ° around pipe direction, and the spacing of vertical direction is
50cm, it is 30cm that convex block 22, which protrudes vertical direction spacing,.
Ribbed stiffener 21 and convex block 22 can effectively enhance concrete cover 1, steel pipe 2,3 three of armored concrete obturator
Between cohesion, significantly improve the ultimate bearing capacity of structure, steel pipe prevented to be detached from concrete section, and improve steel pipe
To the effect of contraction of concrete, the compression strength and tensile strength of built pile with holding structure stabilized soil pavement, can be enhanced.Its
In steel pipe 2 itself also give the constraint in concrete horizontal direction so that structure stretching resistance enhances, and bearing capacity of single pile is higher.
Armored concrete obturator 3 is formed by steel reinforcement cage 31 with concreting, and 31 main body of steel reinforcement cage is by tie hoop 310
It forms, vertical muscle 311 is welded on tie hoop.Filling is by the armored concrete that forms based on tie hoop in steel pipe, together
Sample enhances the compression strength and tensile strength of pile body, and pile body is made to have preferable bearing capacity.
In addition, the present invention because having used concrete cover, can protect nail body steel pipe not corroded, it is resistance to increase structure
Long property extends the built pile service life.
Hoop 312 of putting more energy into, the overall construction intensity of reinforcing steel bar cage 31 are welded between the tie hoop of different level.
Muscle 313 of putting more energy into together is welded every 2 meters on vertical muscle 311, muscle 313 of putting more energy into is perpendicular to 2 axis of steel pipe.
Since pile body is when receiving tensile stress, cracking part is concentrated mainly on the upper part of pile body, therefore, in spiral hoop
Weld short vertical muscle 314 in muscle upper end；Tie hoop is spiraled the structure of density using upper end density of spiraling more than lower end, is further enhanced
The structural strength of pile body upper part enhances the compression strength and tensile strength of pile body.
The section of built pile acts on the raising of frictional force in side-pile using abnormally-structured, by cross section abnormity effect, has
Effect improves combination pile vertical carrying capacity and horizontal bearing capacity.
As the preferred embodiment of the present invention, concrete cover and armored concrete obturator use strength grade
The construction refuse regenerated concreting of C30 forms, and has that environmentally protective, energy saving, light-high-strength and durability be good, cost
Advantage.
With reference to figure 3, thickness of concrete cover thinnest part d1：4-5cm, thickness d2:5-8cm, steel pipe pipe thickness 6-
14mm。
A kind of preparation method of built pile, includes the following steps.
Be prefabricated in the factory steel core：Vertical muscle is welded on tie hoop, is then lifted on tie hoop in steel pipe with one heart；To
Casting concrete in steel pipe, until steel duct treats pulp surface close to opening after filling, maintenance after maintenance completely, is removed to hardening
Mold is removed, obtains steel core.
Cast in situs：Prefabricated blind rivet is lifted to construction site, first smooth location simultaneously pacifies vibrating type machine for placing pipesor piles
Dress is in place, and immersed tube squeezed into projected depth, and nail tip immersed tube is closed during immersed tube, then lifts steel core and sinks in immersed tube and make it and heavy
The vertical concentric fixed placement of pipe.Construction refuse regenerated concrete is poured into a mould by the feed inlet on the upside of immersed tube into immersed tube cavity to fill out
Material, Vibration on Start-up tube drawing, side filler, side vibration sinking tube simultaneously slowly extract immersed tube until immersed tube extracts ground.Treat that this kind half is prefabricated
After the half cast-in-place construction refuse regenerated concrete of odd-shaped cross section-steel pipe combination forming pile 24 hours, excavate and follow closely in foundation surface
Surrounding soil, pours into a mould cushion cap 4 later.It is finally completed a kind of half prefabricated half cast-in-place construction refuse regenerated concrete-steel of odd-shaped cross section
Pipe built pile.
Built pile is prepared using the above method, due to the steel core that can be prefabricated in the factory, there is short time limit, efficient, construction
The advantages of simple and convenient.
Use above specific case is illustrated the present invention, is merely used to help understand the present invention, not limiting
The system present invention.For those skilled in the art, thought according to the present invention can also be made several simple
It deduces, deform or replaces.
