Abstract
The invention discloses a pile foundation structure suitable for a soft soil layer. The pile foundation structure comprises a bearing plate, a cushion layer, an upper pile rod, a lower pile rod and a pile shoe. The upper pile rod is inserted in the soft soil layer, and the upper end of the upper pile rod goes deep into the bearing plate. The cushion layer is arranged between the bearing plate and the soft soil layer. The lower pile rod is arranged at the lower end of the upper pile rod, and the pile shoe is arranged at the bottom of the lower pile rod. The bottom of the lower pile rod goes deep into a bearing layer. The pile foundation structure suitable for the soft soil layer is simple in structure, reasonable in design and good in stability, a prefabricated pile foundation can penetrate the soft soil layer to enter the bearing layer to reduce the settling volume of a borne building, the strength and the shearing resistance force of the pile top portion can be improved, and the cost is effectively reduced.
Description
Technical field
The present invention relates to building field, specially a kind of pile foundation structure suitable for Soft Soil Layer.
Technical background
At present, developing rapidly with building trade, building field for the requirement more and more higher of pile foundation, when running into weak soil
All it is to form composite pile foundation by way of intensive piling during layer, to improve the bearing capacity of soft soil foundation, this mode is constructed slow
And some current pile foundations increase length in order to improve bearing capacity with through Soft Soil Layer, but this can make a bar upper surface slowly,
Stress increase, be unfavorable for stablizing for pile foundation.
The content of the invention
It is an object of the invention to provide a kind of pile foundation structure suitable for Soft Soil Layer, to solve above-mentioned background technology in
The problem of proposition.
For achieving the above object, the present invention provides following technical scheme：A kind of pile foundation structure suitable for Soft Soil Layer, bag
Loading plate, bed course, top stake bar, bottom stake bar and shoe are included, in the top stake bar insertion Soft Soil Layer, the upper end of top stake bar
Go deep in loading plate, bed course is provided between the loading plate and Soft Soil Layer, the bottom stake bar is located at top Zhuan Gan lower ends, bottom
Stake bar bottom is provided with shoe, and bottom Zhuan Gan bottoms are goed deep in supporting course.
Preferably, the top stake bar, bottom stake bar constitute the stake bar structure of pile foundation, and the lateral section of top stake bar is terraced in falling
Shape, the lateral section of bottom stake bar is rectangular.
Preferably, the bottom Zhuan Gan bottoms are provided with shoe, and shoe is in cone.
Preferably, the bed course inserts are stone or gangue.
Compared with prior art, the invention has the beneficial effects as follows：The pile foundation structure of Soft Soil Layer, structure letter should be applied to
Single, reasonable in design, good stability can be such that prefabricated pile foundation enters in bearing bed through Soft Soil Layer, and reduction carries the sedimentation of building
Amount, moreover it is possible to increase the intensity and shearing resistance at stake top position, significantly reduce cost.
Description of the drawings
Fig. 1 is schematic structural view of the invention；
In figure：1 loading plate, 2 bed courses, 3 top stake bars, 4 bottom stake bars, 5 Soft Soil Layers, 6 shoes, 7 supporting courses.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1 is referred to, the present invention provides a kind of technical scheme：A kind of pile foundation structure suitable for Soft Soil Layer, including holding
Support plate 1, bed course 2, top stake bar 3, bottom stake bar 4 and shoe 6, in the insertion of top stake bar 3 Soft Soil Layer 5, top stake bar 3
Upper end is goed deep in loading plate 1, and loading plate 1 is used to carry top-out, and bed course 2 is provided between the loading plate 1 and Soft Soil Layer 5,
The inserts of bed course 2 are stone or gangue, and bed course 2 plays a part of to buffer Soft Soil Layer 5 and loading plate 7, the inserts ratio of bed course 2
Relatively inexpensive, moreover it is possible to cost-effective, the bottom stake bar 4 is located at the lower end of top stake bar 3, and the bottom of bottom stake bar 3 is provided with shoe 6, under
The bottom of portion's stake bar 4 is goed deep in supporting course 7, and the bottom of bottom stake bar 3 is provided with shoe 6, and shoe 6 is in cone, and stake bar is prefabricated pile, stake
The structure of boots 6 can make a bar be easier to go deep into Soft Soil Layer 5 to supporting course 7, top stake bar 3, the stake bar of bottom stake bar 4 one-tenth pile foundations of structure
Structure, the lateral section of top stake bar 3 is in inverted trapezoidal, and the lateral section of bottom stake bar 4 is rectangular, due to the cross section of top stake bar 3
Product is larger, when the length of stake bar is increased to prevent building settlement, effectively increases the weight capacity and shearing resistance of a bar, should
Suitable for the pile foundation structure of Soft Soil Layer, simple structure is reasonable in design, good stability, and prefabricated pile foundation can be made to enter through Soft Soil Layer
Enter in bearing bed, reduction carries the settling amount of building, moreover it is possible to increases the intensity and shearing resistance at stake top position, significantly reduces
Cost.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of spirit or essential attributes without departing substantially from the present invention, the present invention can be in other specific forms realized.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as and limit involved claim.
Moreover, it will be appreciated that although this specification is been described by according to embodiment, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of description is only that for clarity those skilled in the art should
Using description as an entirety, the technical scheme in each embodiment can also Jing it is appropriately combined, form those skilled in the art
Understandable other embodiment.
