Abstract
The invention discloses a kind of concrete to fill out the stake of core perforated pipe and construction method, in the perforated pipe stake static pressure pile-sinking construction time, forms concrete core to the perforated pipe pile pipe intra-bladder instillation concrete that draining finishes, technical key point is to include the following steps: to lay out pile；Positioning；Static pressure pile-sinking；Soil body discharging consolidation: in the perforated pipe stake static pressure pile-sinking construction time, the pore water being completed in the foundation soil body in pile sinking region is discharged into tubular pole lumen by pile body drainage hole, accelerates dissipation of excess pore-water pressure；Lumen draws water；Core is filled out in lumen.The solution have the advantages that: the defects of overcoming the reduction of prefabricated concrete pipe pile bearing capacity caused by pile body aperture and unbearable horizontal loading, dissipation of excess pore-water pressure can effectively be accelerated in the perforated pipe stake static pressure pile-sinking construction time, after draining substantially, concrete core is formed from the inside concrete perfusion of tubular pole mouth, it is ensured that perforated pipe stake there are enough bearing capacities in the carrying stage and can undertake part of horizontal load.
Description
Technical field
The present invention relates to technical field of building construction, specially a kind of concrete fills out the stake of core perforated pipe and construction method.
Background technique
Prefabricated concrete pipe pile is widely used in all kinds of foundation treatments at present, but effect of driving pile is always
This aspect yet unresolved issue, especially handle moisture content is high, intensity is low, poor permeability soft soil foundation when, static pressure
Excess pore water pressure caused by pile sinking easily causes a series of harm such as adjacent stake offset, broken pile.According to related engineering practice and
Theoretical data shows to design by reasonable pile body and construction technology can effectively mitigate pile sinking effect, therefore perforated pipe stake
Technology is come into being, and by reasonably opening up permeable hole in pile body, accelerates the dissipation of excess pore-water pressure of tubular pole piling construction phase,
Mitigate soil compaction during pile driving harm.
But pile body aperture certainly will will cause the reduction of bearing capacity, and in the prior art, Authorization Notice No. is
A kind of perforated pipe stake for deep soft soil treatment is disclosed in a Chinese invention patent file of CN201620410U, according to
Perforated pipe stake related research result may indicate that perforated pipe stake can effectively mitigate effect of driving pile, but pile body aperture certainly will cause
The reduction of tubular pole bearing capacity destroys the defects of pile body globality, unbearable horizontal loading and tapping stress concentration phenomenon.For
This, it is proposed that a kind of concrete fills out the stake of core perforated pipe and construction method.
Summary of the invention
The purpose of the present invention is to provide a kind of concrete to fill out the stake of core perforated pipe and construction method, it is intended to solve perforated pipe stake
Adverse effect caused by pile body aperture.
To achieve the above object, the present invention provides a kind of concrete and fills out core perforated pipe pile construction method, including the following steps:
(1) it lays out pile: laying stake position on soft foundation；
(2) it positions: perforated pipe stake is lifted into default stake position；
(3) static pressure pile-sinking: after pile press machine is in place, static pressure pile-sinking is carried out to perforated pipe stake and reaches designated depth；
(4) in the perforated pipe stake static pressure pile-sinking construction time, the hole in the foundation soil body in pile sinking region soil body discharging consolidation: is completed
Water is discharged into tubular pole lumen by pile body drainage hole, accelerates dissipation of excess pore-water pressure；
(5) lumen draws water: being completely drawn out intraluminal pore water by suction pump；
(6) core is filled out in lumen: after drawing water, filling out core to perforated pipe pile pipe intra-bladder instillation concrete, sufficiently vibrate in the process；
(7) it shifts: repeating step (1) to step (6) and carry out next perforated pipe pile driving construction.
The present invention provides a kind of concrete and fills out core perforated pipe stake, fills out core perforated pipe pile driving construction side using comprising above-mentioned concrete
Method, including the stake of precast concrete perforated pipe and concrete core, it is characterised in that: the cylindrical tubular pole of precast concrete perforated pipe stake
Several pairs of through holes are offered on wall, concrete perfusion fill out core at mixed into lumen after pile peripheral earth draining finishes substantially
Solidifying core.
Compared with prior art, the beneficial effects of the present invention are:
In original perforated pipe pile foundation, lumen and pile body hole are filled by rear concrete perfusion, both ensure that
The advantages of original acceleration foundation soil body dissipation of excess pore-water pressure of perforated pipe stake mitigates effect of driving pile, and compensate for aperture and lead
Tubular pole bearing capacity is caused to be reduced this defect, while improving the globality of tubular pole and rigidity to undertake horizontal loading, and energy
Effectively avoid the appearance of pile body tapping stress concentration phenomenon.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear-complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Fig. 2, precast concrete perforated pipe stake 4 is lifted into default stake position, piling machinery 5 at engineering construction scene
It is consistent with conventional tubular pole static pressure pile-sinking process that 4 pile sinking of precast concrete perforated pipe stake is reached into designated depth after in place, due to heavy
Stake soil compaction effect, the pore water meeting in the 4 static pressure pile-sinking construction time of precast concrete perforated pipe stake, in the foundation soil body in pile sinking region
It is discharged into 4 lumen of concrete perforated pipe stake by pile body through hole 2, accelerates 6 pressure dissipation of pore water；It will by suction pump 7
The intraluminal pore water 6 of concrete perforated pipe stake 4 is completely drawn out, and after drawing water, has hole to concrete by concrete mixer 8
Concrete perfusion 3 carries out filling out core in 4 official jargon of tubular pole, sufficiently vibrates in the process, is to fill out the concrete perforated pipe after core shown in Fig. 1
4 Structure of cross section schematic diagrames of stake, concrete are filled into concrete core 3 to lumen and 1 through hole of cylindrical tube pile lining, 2 hole,
So that cylindrical tube pile lining 1 restores completely, ensure that the acceleration foundation soil body excess pore water of precast concrete perforated pipe stake 4 again
On the basis of 6 pressure dissipations mitigate the advantages of effect of driving pile, compensating for aperture causes precast concrete perforated pipe stake 4 to carry
Power is reduced this defect, while the through hole 2 for filling up cylindrical tube pile lining 1 improves the entirety of precast concrete perforated pipe stake 4
Property with rigidity can undertake horizontal loading, and can effectively avoid stress concentration phenomenon at the through hole 2 of cylindrical tube pile lining 1
Occur, to meet different design requirements.
