Description
Technical field
The utility model is related to building construction technology fields, and in particular to a kind of load-bearing pile foundation structure.
Background technology
Currently, in Design of Architecture Pile Foundation, the stake of same length is generally used in same structure unit, including prefabricated pile,
Bored concrete pile.Under this structure, the stake end of same length is located at same supporting course.Cause cost high and long in time limit.Due to
Within the scope of pile body harder soil layer often there are two, including 30-40 meters of the powder soil horizon of buried depth shallower (15-20 meters) and buried depth
Hard stratum (silt/flour sand etc.).The bearing capacity for how giving full play to shallower hard stratum, to effectively improve pile foundation utilization ratio,
To save the duration, saving construction cost, become we must face the technical issues of.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provide a kind of bearing pile base junction
Structure, it is intended to solve generally to lead to carrying for pile foundation cost using the stake of same length in the same structure unit of current load-bearing pile foundation
High and long in time limit problem.
Technical solution is used by realize the purpose of this utility model：
A kind of load-bearing pile foundation structure, including be embedded in respectively by different predetermined depths multiple first bearing piles of underground with it is multiple
Second bearing pile；First bearing pile is alternatively arranged with the second bearing pile, and first bearing pile and the second bearing pile are equal
For with bored concrete pile, it is long stake, stake that the upper end of first bearing pile and the second bearing pile, which supports bearing plate, first bearing pile,
End is located at pan soil supporting course；Second bearing pile is stub, and stake end is located at silt supporting course；First bearing pile has stake root,
The upper end of the stake root is tapered portion, and the upper end of the tapered portion is force bearing disk, be formed on the outside of the force bearing disk it is multiple to
Under the inclination load portion that is inclined outwardly, the inclination load portion is deep into soil；On the pile of second bearing pile from upper and
Under be formed with the load portions of multiple spaced cone-shapeds.
The long stake is cylinder pile, and the cylinder pile includes steel reinforcement cage and pours integral coagulation with the steel reinforcement cage
Soil pours building body.
The stake root is round or rectangle.
The utility model efficiently utilizes the different structure of pan soil and silt, realizes profit by above technical scheme
Fill column into load-bearing pillar with long-short pile, while ensure that load bearing effect, can save the duration to a certain extent, save building
Cost, and due to the special construction of two kinds of load-bearing pillars, stability is stronger.
Description of the drawings
Fig. 1 show the structural schematic diagram of the load-bearing pile foundation structure of the utility model embodiment offer；
Fig. 2 show the schematic top plan view of the force-bearing base of the first bearing pile of the utility model embodiment offer；
Fig. 3 show the diagrammatic cross-section of the pile body of the first bearing pile of the utility model embodiment offer.
Specific implementation mode
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place
The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-3, a kind of load-bearing pile foundation structure, including respectively multiple the of underground are embedded in by different predetermined depths
One bearing pile 2 and multiple second bearing piles 3；First bearing pile is alternatively arranged with the second bearing pile, and first load-bearing
Stake is the upper end support bearing plate 4 of first bearing pile and the second bearing pile with bored concrete pile with the second bearing pile, and described the
One bearing pile is long stake, and stake end is located at pan soil supporting course；Second bearing pile is stub, and stake end is located at silt supporting course；Described
One bearing pile have stake root 25, the upper end of the stake root be under narrow wide tapered portion 22, the upper end of the tapered portion is load
The outside of disk 21, the ontology 221 of the circular discoid of the force bearing disk is formed with multiple downwardly and outwardly inclined inclination load portions
212, the inclination load portion is deep into soil；Multiple intervals are formed on the pile 31 of second bearing pile from top to bottom to set
The cone-shaped set or horn-like load portion 32.
The long stake is cylinder pile, and the main body 20 of the cylinder pile includes that steel reinforcement cage 23 and being poured with the steel reinforcement cage is built up
The concreting body 24 of one.Long stake uses bored concrete pile, stake end to be located at deeper pan soil supporting course, and general stake is 30-40 meters long.
Wherein, the stake root is round or rectangle.
Second bearing pile by being formed with multiple spaced cone-shapeds or horn-like from top to bottom on pile
Load portion increases substantially bearing capacity of single pile by adopting such structure, can enhance the bearing capacity of the second bearing pile,
And settle also very little.
First bearing pile has stake root, and the upper end of the stake root is tapered portion, and the upper end of the tapered portion is load
Disk is formed with multiple downwardly and outwardly inclined inclination load portions on the outside of the force bearing disk, and the inclination load portion is deep into soil
In, by using such bearing structure, the bottom bearing capacity of the first bearing pile can be enhanced, increase substantially single pile bearing
Power, and settle also very little.
When it is implemented, first bearing pile is embedded in underground higher depth, and using the closely knit soil layer of subsurface as
Second bearing pile is embedded in the shallower place in underground by its supporting course, and with relatively uncompacted powder soil horizon of subsurface for it
Supporting course can increase the bearing capacity of the first bearing pile since the bottom of the first bearing pile has force bearing disk and tilts load portion,
Second load-bearing pillar is identical with the first bearing pile so as to play due to there are multiple downwardly and outwardly inclined inclination load portions
Bearing capacity, but since column length shortens, saves that stake is long, thus has saved the cost of manufacture of stake, also improves apply to a certain extent
Work speed.
The utility model efficiently utilizes the different structure of pan soil and silt, realizes profit by above technical scheme
Fill column into load-bearing pillar with long-short pile, while ensure that load bearing effect, can save the duration to a certain extent, save building
Cost, and due to the special construction of two kinds of load-bearing pillars, stability is stronger.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art
For logical technical staff, without departing from the principle of this utility model, several improvements and modifications can also be made, these change
The scope of protection of the utility model is also should be regarded as into retouching.
