Description
Technical field
The utility model relates to a kind of inner bearing type enlarged footing tube pile structures, belong to pile tube technical field.
Background technique
Prestressed concrete pipe pile (PHC) is the widely used pile-type in current architectural engineering, has quality
Well, the advantages that intensity is high, speed of application is fast；As other type stakes, tubular pole be also by end resistance and end resistance come
Load is undertaken, when end resistance is smaller, to reach design bearing capacity, higher stake must be just obtained by longer pile body
End resistance.Longer pile body increases cost and difficulty of construction, occupies the more underground space, and it is tired to may cause pile sinking
The problems such as difficult, quick-fried stake.Meanwhile soil compaction effect caused by piling process may cause the foundation pile previously constructed and float, and reduce foundation pile
Bearing capacity, may cause pile foundation engineering and be not available.Therefore, it by designing a kind of inner bearing type enlarged footing tube pile structure, solves
It has determined problem above.
Summary of the invention
Technical problem to be solved by the utility model is to provide a kind of inner bearing type enlarged footing tube pile structures, it is solved
Currently in order to higher end resistance is obtained, and by the way of extends tubular pole length of embedment, the thus longer stake of caused tubular pole
Body increases cost and difficulty of construction, occupies the more underground space, and the problem of may cause pile sinking difficult, quick-fried stake.
Technical problem to be solved in the utility model takes following technical scheme to realize:
A kind of inner bearing type enlarged footing tube pile structure, it includes prefabricated tubular pile, expansion tablet fixing pipe, taper pile top, expansion
Tablet, tablet fixed ring, tablet expansion pipe, the prefabricated tubular pile lower end are fixed with expansion tablet fixing pipe, and expansion tablet is fixed
Pipe lower end is fixed with taper pile top, and the expansion tablet fixing pipe surrounding offers multiple expansion slots, places in each expansion slot
One expansion tablet, crosscutting from expansion slot top, expansion tablet fixing pipe is made of upper and lower two parts, and top is upper fixing pipe,
Lower part is lower fixing pipe, and tablet fixed ring is equipped between upper fixing pipe, lower fixing pipe, and the expansion tablet top is equipped with rotation
Hole, expansion tablet in tablet fixed ring, in the tablet expansion pipe insertion prefabricated tubular pile, expand tablet top by rotation hole string
Portion is equipped with scarf, and when expansion tablet withdraws expansion slot, tablet expansion pipe lower end is pressed in just on expansion tablet scarf, drives
It is opened out of expansion slot dynamic expansion tablet lower part.
As preferred embodiment, fixed tube bottom end, lower fixing pipe top are respectively equipped with annular groove, and tablet fixed ring is solid
Determine in a ring groove.
As preferred embodiment, to cut the native edge of a knife on the outside of the expansion tablet, inside is wide face knife spine.
As preferred embodiment, the gradually smaller steel pipe of tablet expansion Guan Youyi group outer diameter is formed, maximum outside diameter it is rigid
The outer diameter that piece expands pipe is less than prefabricated tubular pile internal diameter.As expansion tablet opening angle becomes larger, replaces and smaller be adapted to therewith
Tablet expansion pipe, when expansion, can be more laborsaving.
The quantity of tablet and length can be expanded on expansion pile head can be fabricated to difference according to pile bearing capacity design value
Size reduces construction cost so as to shorten stake is long.
The beneficial effects of the utility model are: the taper pile top of prefabricated tubular pile and the expansion tablet fixing pipe insertion soil body is pre-
If depth, the rotatable expansion tablet of setting in the expansion slot of tablet fixing pipe is expanded, it is rigid to push expansion by tablet expansion pipe
The scarf of piece upper end, driving expansion tablet lower part expansion is protruded into the soil body, then to slip casting at pile crown, being formed has enlarged footing
Foundation pile system, enlarged footing improve foundation pile bearing capacity, but also foundation pile rising phenomenon effectively weakens, can obtain higher
End resistance；Significantly reduce difficulty of construction and prefabricated tubular pile cost.

In figure: prefabricated tubular pile 1 expands tablet fixing pipe 2, and taper pile top 3 expands tablet 4, tablet fixed ring 5, and tablet expands
Pipe 6, expansion slot 7, upper fixing pipe 8, lower fixing pipe 9, rotation hole 10, annular groove 11 cut the native edge of a knife 12, wide face knife spine 13.
Specific embodiment
In order to which the technical means, creative features, achievable purpose and effectiveness to the utility model are easy to understand, tie below
Conjunction is specifically illustrating, and the utility model is further described.
As Figure 1-Figure 4, a kind of inner bearing type enlarged footing tube pile structure, it includes prefabricated tubular pile 1, expansion tablet fixing pipe
2, taper pile top 3, expansion tablet 4, tablet fixed ring 5, tablet expand pipe 6, and 1 lower end of prefabricated tubular pile is fixed with expansion tablet and fixes
Pipe 2, expansion 2 lower end of tablet fixing pipe are fixed with taper pile top 3, and expansion 2 surrounding of tablet fixing pipe offers multiple expansion slots 7,
An expansion tablet 4 is placed in each expansion slot 7, it is crosscutting from 7 top of expansion slot, tablet fixing pipe 2 is expanded by upper and lower two parts
It constituting, top is upper fixing pipe 8, and lower part is lower fixing pipe 9, tablet fixed ring 5 is equipped between upper fixing pipe 8, lower fixing pipe 9,
