Description
Technical field
This utility model relates generally to construction engineering technical field, the most prefabricated separate type uplift pile.
Background technology
For the area that level of ground water is higher, when dead load and upper load cannot balance the buoyancy of subsoil water,
Structure need to carry out Anti-floating design.In Anti-floating design most widely used with uplift pile, uplift pile refer to when architectural engineering underground structure such as
Fruit has when less than the part of Soil Surrounding water level, in order to offset the buoyancy that in soil, structure is produced by water and the stake beaten.Anti-
Pile pulling is broadly divided into prefabricated uplift pile and cast in situs uplift pile by construction technology.Precast construction meets the trend of architectural industrialization
And trend, have a extensive future.
The existing main withdrawal resistance of prefabricated uplift pile depends on pile side resistance, and once buoyancy is more than withdrawal resistance, i.e. shows
Uplift pile loses function, and existing prefabricated uplift pile withdrawal resistance is limited, is difficult to increase, limits the range of application of uplift pile.
Utility model content
For solving the deficiencies in the prior art, this utility model provides prefabricated separate type uplift pile.It can provide bigger
Withdrawal resistance, expand uplift pile range of application.
This utility model for achieving the above object, is achieved through the following technical solutions: prefabricated separate type uplift pile, including stake
Body, described pile body is hollow pile body, and the inside diameter of described pile body is gradually reduced in rounding mesa-shaped from top to bottom, in described pile body
Arranging linkage section, the diameter of described linkage section is gradually reduced in rounding mesa-shaped from top to bottom, the top diameter of described linkage section and
Base diameter is respectively less than the top diameter of pile body, and the top diameter of described linkage section is more than the base diameter of pile body, described connection
The base diameter of section, less than the base diameter of pile body, described linkage section arranges multiple perforation, arranges stake bottom described linkage section
Head.
Flange joint is passed through between described linkage section and pile crown.
Contrast prior art, the beneficial effects of the utility model are:
1, the soil body duct by linkage section in this utility model, forms entirety with linkage section and bottom pile crown, is equivalent to
Expanding the pile crown of bottom pile body, provide bigger withdrawal resistance for uplift pile, performance is largely increased, and expands uplift pile
Range of application.
2, this utility model middle connecting segment and pile crown Flange joint, convenient disassembly, bonding strength is high, and tightness is good, is suitable for
The application of uplift pile and the construction features of the prefabricated separation of this utility model.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation；
Accompanying drawing 2 is that this utility model uses state reference map.
Label shown in accompanying drawing: 1, pile body；2, linkage section；3, perforation；4, pile crown；5, the soil body.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be understood that these embodiments are only used for
This utility model is described rather than limits scope of the present utility model.In addition, it is to be understood that reading this utility model instruction
Content after, this utility model can be made various changes or modifications by those skilled in the art, and these equivalent form of values fall equally
In scope defined herein.
Prefabricated separate type uplift pile, including pile body 1, described pile body 1 is hollow pile body, the inside diameter of described pile body 1 from
On be down gradually reduced in rounding mesa-shaped, linkage section 2 is set in described pile body 1, the diameter of described linkage section 2 from top to bottom in fall
Round table-like being gradually reduced, the top diameter of described linkage section 2 and base diameter are respectively less than the top diameter of pile body 1, described connection
The top diameter of section 2 is more than the base diameter of pile body 1, and the base diameter of described linkage section 2 is less than the base diameter of pile body 1, institute
State and multiple perforation 3 is set on linkage section 2, bottom described linkage section 2, pile crown 4 is set.In this utility model, the soil body passes through linkage section
Duct, form entirety with linkage section and bottom pile crown, be equivalent to expand the pile crown of bottom pile body, provide more for uplift pile
Big withdrawal resistance, performance is largely increased, and expands the range of application of uplift pile.
Further, Flange joint is passed through between described linkage section 2 and pile crown 4.This utility model middle connecting segment and pile crown
Flange joint, convenient disassembly, bonding strength is high, and tightness is good, is suitable for the application of uplift pile and the prefabricated separation of this utility model
Construction features.
In use, due to the top diameter of linkage section and base diameter, to be respectively less than the top of pile body straight for this utility model
Footpath, can put into linkage section from pile body top, and the top diameter of linkage section is more than the base diameter of pile body, and the bottom of linkage section is straight
Footpath is less than the base diameter of pile body, and linkage section can pass pile body smoothly and be unlikely to depart from pile body, and linkage section passes part
With pile crown Flange joint.It should be noted that the arrangement of reinforcement of pile body and linkage section is satisfied by related request.Then pile body is squeezed into ground
Under, after pile body is driven underground, use press device, such as forcing press, downwards linear motion mechanical hand, or screw-nut to
Underdrive devices etc., press downward to suitable distance by linkage section and prefabricated pile crown, and thus pile body and pile crown separating distance become big, ground
Under the soil body under the effect of soil pressure through connect in duct, now the soil body becomes expansion pile head with prefabricated pile capitiform, thus
Improve the withdrawal resistance of stake.
Embodiment 1:
Prefabricated separate type uplift pile, including pile body 1, described pile body 1 is hollow pile body, the inside diameter of described pile body 1 from
On be down gradually reduced in rounding mesa-shaped, linkage section 2 is set in described pile body 1, the diameter of described linkage section 2 from top to bottom in fall
Round table-like being gradually reduced, the top diameter of described linkage section 2 and base diameter are respectively less than the top diameter of pile body 1, described connection
The top diameter of section 2 is more than the base diameter of pile body 1, and the base diameter of described linkage section 2 is less than the base diameter of pile body 1, institute
State and multiple perforation 3 is set on linkage section 2, bottom described linkage section 2, pile crown 4 is set.In this utility model, the soil body passes through linkage section
Duct, form entirety with linkage section and bottom pile crown, be equivalent to expand the pile crown of bottom pile body, provide more for uplift pile
Big withdrawal resistance, performance is largely increased, and expands the range of application of uplift pile.Method is passed through between described linkage section 2 and pile crown 4
Blue connection.Can use between linkage section with pile crown weld, threaded, Flange joint etc., the preferred Flange joint of the present embodiment.
First linkage section and pile crown are separately fixed on a ring flange, then plus flange gasket between two ring flanges, finally use
Two ring flange tensions are made it combine closely by bolt.Flange joint convenient disassembly, bonding strength is high, and tightness is good, suitable
Close application and the construction features of the prefabricated separation of this utility model of uplift pile.The present embodiment provides the benefit that: the present embodiment profit
With linkage section and its underpart pile crown, form expansion pile head with the soil body, thus improve the anti-pulling capacity of pile body so that uplift pile
