Description
[technical field]
The utility model relates to the piling construction technical field, mainly is pipe pore-creating filling pile structure in a kind of heavy two-tube pulling out.
[background technology]
As everyone knows; When surface structures was built on the ground, sizable pressure will be born in ground, and is firm for what guarantee to build; Must guarantee that there is enough renitent intensity on ground; Therefore need reinforce or improve the mode of bearing on ground to the ground of bearing building, make most of weight of building pass to the very dark position of below ground, to improve ability to bear to building through stake so be employed in the method for driving piles on the ground.
Pore-creating filling pile method in the existing piling technology typically has two kinds, and first kind is vibrator pipe sinking cast-in-place pile, and this pile-driving method is through vibration the ground desired location to be squeezed in stake, extracts behind the concrete perfusion.But this method is for squeeze soil fully, and its long-pending serious words of native effect can make roadbuilding occur being squeezed splitting; Secondly the work of pile tube distinguishes that the stake point is closed when sinking, and makes that an end area is big, end resistance is big, the pile sinking difficulty.The stake footpath of normal conditions vibrator pipe sinking cast-in-place pile is less, and general diameter is less than 0.5m; In immersed tube, put in addition behind reinforcing cage and the placing of concrete when pulling out immersed tube in the vibration, live sometimes and distinguish that a point do not open or do not open the quality of influence stake fully.Second kind is the rig pore-forming; Rotary drilling rig piling mode is the most influential equipment in the present rig pore-creating filling pile construction; What it adopted is to revolve with bucket to take soil; But because the soil in viscosity weak soil zone is difficult to pour out from revolving in the bucket, rotary drilling rig can't be constructed, particularly in areas such as Shanghai, Wenzhou.And at some soil layer, hole or shrinkage cavity can appear collapsing behind the rotary drilling rig pore-forming, need steel casing down, this can make construction complicated, increase construction cost and efficiency of construction reduced.
[summary of the invention]
The purpose of the utility model is in order to solve deficiency of the prior art, and pipe pore-creating filling pile structure in a kind of novel structure, safe and reliable, heavy two-tube the pulling out that efficiency of construction is high is provided.
For realizing above-mentioned purpose; Pipe pore-creating filling pile structure in a kind of heavy two-tube pulling out is provided; Comprise the adjustable vibrating hammer of eccentric moment, folder post device, interior pipe, outer tube, make pylon or jack lift; Pipe is arranged in the outer tube in it is characterized in that, interior pipe is connected with folder post device with the outer tube top, and folder post device top connects adjustable vibrating hammer of eccentric moment or hoist engine.
Described inner and outer pipe gap is 5-10mm.
Pipe and outer tube bottom is openend in described.
The utility model is compared with prior art, and its advantage is:
(1) because opening immersed tube end resistance makes the stake pipe sink more easily for a short time;
(2) can become large diameter pile, also can make greater than the stake of 1m like diameter;
(3) have only the part regolith to take out, soil compaction effect is not obvious;
(4) the outer tube lower end just belonged to opening originally, and when in vibration, pulling out outer tube, the stake soil that is poured into is difficult for by modification, and pile quality is good.
(5) wide accommodation of construction soil, both having made is the viscosity weak soil, can construct as usual, and the phenomenon that the regolith does not come out can not occur;
(6) efficiency of construction is high, and ordinary circumstance is only carried interior pipe with once on, just can be with the soil completion emptying of outer tube, and rotary drilling digger need do many times could the pile hole;
(7) sink to the outer tube in the soil under, played the effect of completion retaining wall, hole or shrinkage cavity phenomenon can not occur collapsing;
(8) have part during two-tube vibration-sunk and squeeze soil, this part soil compaction effect make the stake that become to hold the power of planting bigger.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described further, the structure of this device and principle are very clearly concerning this professional people.
It is bitubular steel pipe and special-purpose pylon or the jack lift beaten of 5-10mm that there are the adjustable vibrating hammer of eccentric moment and folder post device, inner and outer pipe gap in the capital equipment system in the utility model when operation.The use step of the utility model is:
1. shown in accompanying drawing 1, interior pipe box is clamped inner and outer pipe with folder post device in outer tube;
2. vibrating hammer vibration makes regolith refinement, loose, and inner and outer pipes sinks together, has soil to get in the interior pipe, because the inner and outer pipe gap is little, soil enters in the gap few, therefore can ignore;
3. shown in accompanying drawing 3; Stop vibration after sinking to the degree of depth of requirement, change the folder piling method and makes pile chuck only clamp interior pipe, start hoist engine and make vibrating hammer under the friction state, pull out interior pipe; Up to extracting fully; Since inaccessible principle, the frictional force effect between the soil in the promptly interior pipe and the inwall of interior pipe, and the soil in making in the pipe can not be poured out when in quiet pulling out, managing;
4. move pile frame or crane slightly and make interior pipe remove the outer mouth of pipe, start the vibrating hammer vibration, the soil in the interior pipe is constantly being come out in interior pipe under the vibrational state, pour out up to whole regoliths;
5. sink to the outer tube in soil, its inside almost is not have soil fully, and reinforcing cage is put into, and concrete perfusion is up to filling;
6. shown in accompanying drawing 2, use the clamp clamps outer tube, start the vibrating hammer vibration, utilize the vibration effect that outer tube is extracted, accomplished stake simultaneously.
When using the utility model pile pulling, its concrete works step is following:
(1), interior pipe box is gone in the outer tube, clamp inner and outer pipe with folder post device, inner tube diameter is greater than old stake external diameter;
(2), vibrating hammer vibration, inner and outer pipe sinks together, in managing in native and old stake gets into together;
(3), sink to the old stake stake end after; Changing the folder piling method makes pile chuck only clamp interior pipe; Starting hoist engine makes vibration hammer under the friction state, pull out interior pipe; Up to extracting fully; Because inaccessible principle; Frictional force effect between the soil in the promptly interior pipe and the inwall of interior pipe, soil in making in the pipe and old stake can not be poured out when in quiet pulling out, managing;
(4), move pile frame or crane make in pipe remove the outer mouth of pipe, start the vibrating hammer vibration, the soil in the interior pipe and old are constantly being come out in interior pipe under the vibrational state, pour out up to whole regoliths.
