Abstract
A kind of pile pier integral structure, is provided with reinforcement cage, and the peg equipped with laterally setting on the side wall of bridge pier bottom, Bored Pile Foundation between Bored Pile Foundation and bridge pier bottom and is also equipped with prestress wire.This kind of pile pier integral structure, its structural strength is high, and shearing resistance, resistance to plucking and flexural capacity are strong, with higher structural strength and wider array of applicability, while suitable for the building of centering type stress.
Description
Technical field
The utility model is related to the integral structure of Bored Pile Foundation and bridge pier.
Background technology
The integrated structure of existing building infrastructure, its pile foundation and pier, mostly pile foundation elevates above the soil, and first pours ground end
Part, above ground portion reserved steel bar cage treats pier bottom insertion after-pouring above ground portion formation suspended deck structure.Such a pile pier structure pressure-bearing
Performance is good, the need for being well positioned to meet vertical load building, but for some buildings for needing to bear transverse load, it holds
Load performance is then poor, and resistance to plucking and flexural capacity are poor, there is potential safety hazard.
The content of the invention
The utility model aims to provide a kind of pile pier integral structure with good resistance to plucking and flexural capacity, to improve it
Structural strength and the scope of application, the need for meeting different buildings.
Pile pier integral structure described in the utility model, including Bored Pile Foundation and bridge pier, the top of Bored Pile Foundation
It is above the ground level, and a boundary line that scoops for Bored Pile Foundation is less than ground certain distance, the steel reinforcement cage of foundation pile extends to top by bottom
End；The bottom of bridge pier is embedded in Bored Pile Foundation, and is placed in and is scooped in a boundary line, and bridge pier bottom is located at the side wall of the part of subsurface
Surface spreads all over the peg crossed out, separately has reinforcement cage, reinforcement cage is arranged at outside the peg of bridge pier bottom, and reinforcement
It is above the ground level at the top of cage.
Pile pier integral structure described in the utility model, scoops a boundary line and locates below ground level, and stake top is located at ground
On, bridge pier bottom, which is stretched into below ground and is supported on, scoops a boundary line plane, and sets peg and reinforcement cage in bridge pier side wall,
After concreting, its pile foundation is combined closely by steel reinforcement cage top section, bridge pier by peg and reinforcement cage with pouring section, from
And pile foundation is formd the structure of a monoblock type with bridge pier, its intensity connected has obtained significantly being lifted, and has bridge pier
Good resistance to plucking and flexural capacity.
Described pile pier integral structure, the surrounding of the steel reinforcement cage of Bored Pile Foundation is disposed with many prestress wires,
The two ends of each prestress wire are strained and fixed at the top and bottom of steel reinforcement cage respectively.Due to arranging prestress steel on steel reinforcement cage
Twisted wire, after pile pier is poured and finished, can make it produce prestressing force, so that in bridge pier by level with stretch-draw prestressing force steel strand wires
When power produces larger moment of flexure, it can be balanced by prestressing force, so as to further improve the resistance to plucking and anti-folding of bridge pier
Ability so that the pile pier integral structure disclosure satisfy that the use requirement of centering type stress, can resist top bridge pier transmission
Moment of flexure.
Brief description of the drawings
Fig. 1 is the structural representation of pile pier integral structure.
Fig. 2 is the partial enlarged drawing of pile pier integral structure shown in Fig. 1.
Fig. 3 is the bridge pier of pile pier integral structure shown in Fig. 1 and the structural representation of peg.
Embodiment
A kind of pile pier integral structure, including Bored Pile Foundation 1 and L-shaped bridge pier 2, the top of Bored Pile Foundation is above Ground
Face, and a boundary line that scoops for Bored Pile Foundation is less than ground certain distance, the steel reinforcement cage of foundation pile extends to top by bottom；Bridge pier
Bottom be embedded in Bored Pile Foundation, and be placed in and scoop in a boundary line, bridge pier bottom is located at the sidewall surfaces time of the part of subsurface
The peg 4 that cloth is crossed out, separately there is reinforcement cage 3, and reinforcement cage is arranged at outside the peg of bridge pier bottom, and reinforcement cage
Top is above the ground level.
As shown in Figure 1, 2, horizontal line M is above-ground route in figure, horizontal line N to scoop a boundary line, reinforcement cage be arranged at this two
Between bar horizontal line, be both installed in Bored Pile Foundation, but with bridge pier bottom connection function so that the structure for improving pile pier is strong
Degree；And peg is set in bridge pier bottom, then the bonding strength between reinforcement cage on the one hand can be improved, on the other hand can also
Improve shearing resistance, resistance to plucking and the flexural capacity of bridge pier；And the structure of peg and reinforcement cage, then it can further improve its structure strong
Degree.
Described pile pier integral structure, the surrounding of the steel reinforcement cage of Bored Pile Foundation 1 is disposed with many prestress wires
5, the two ends of each prestress wire are strained and fixed at the top and bottom of steel reinforcement cage respectively.Due to arranging prestressing force on steel reinforcement cage
Steel strand wires, after pile pier is poured and finished, can make it produce prestressing force, so that in bridge pier by water with stretch-draw prestressing force steel strand wires
When flat power produces larger moment of flexure, it can be balanced by prestressing force, so as to further improve the resistance to plucking of bridge pier and resist
Folding ability so that the pile pier integral structure disclosure satisfy that the use requirement of centering type stress, can resist top bridge pier transmission
Moment of flexure.
The periphery of Bored Pile Foundation 1 is provided with steel pile casting 10, and the top protrusion of steel pile casting is above the ground level.In Bored Pile Foundation
Interior setting steel pile casting, on the one hand can provide drilled pile aperture protecting effect, on the other hand can be played again in the later stage and give underground work
Dress, ground frock, bridge pier lift the function of centre of location Points And lines.
