Abstract
The utility model provides a novel PTC type has a heliciform hole tubular pile that is used for deep soft base to handle, it includes cylindrical tubular pile wall, hole two parts, characterized by opens the three round hole that equilateral triangle distributes that is at the same height of cylindrical tubular pile wall, then locates trompil again to 10 times of apertures with the three hole integral rotary 60o back -porch stake of opening is rectangular, and it has a plurality of holes that are the heliciform distribution on the tubular pile wall to open according to this kind of trompil mode top -down. The utility model has the beneficial effects of: in the tubular pile pile sinking construction time, because pile sinking squeezing effect has produced excess pore water pressure, native mesopore water can initiatively get into porose tubular pile inner chamber through the stake hole, reduces the excess pore water pressure maximum value, alleviates the harm that the pile sinking caused to neighbour's stake, in the construction intermittent type phase, along with excess pore water pressure's dissipation, tu zhongkongxishui also can get into the tubular pile inner chamber through the stake hole to excess pore -water pressure dissipation saves the time limit for a project with higher speed.
Description
Technical field
The utility model relates to a kind of pile tube, particularly relates to the porose pile tube that a kind of hole distributes in the shape of a spiral.
Background technology
Riverine and the coastal area in China, there is deep soft soil foundation, therefore the porose pile tube of prestressing force is widely used in all kinds of construction project of China, and it has remarkable superiority in bearing capacity, bending resistance, extraction-resistant behavior etc., and it can control uneven settlement of foundation effectively.But static pressure pile-sinking process can produce obvious soil compaction effect, a series of harmful effect is caused on engineering: the impact on adjacent stake when comprising pile sinking, " floating stake " phenomenon can be produced; On the impact of around building, as caused the differential settlement of contiguous building; Produce too high excess pore water pressure during pile sinking, certain impact can be produced on the bearing capacity of ground; On the impact of pile peripheral earth shear strength during pile sinking, pile peripheral earth shear strength can be made obviously to reduce.In order to alleviate the soil compaction effect produced in pile driving process, the dissipation accelerating super interstitial hydraulic pressure, ensure pile quality, this just must take certain measure, proof and theory deduction can learn that arranging some circular holes on request at pile tube tube wall can alleviate the adverse effect of static pressure pile-sinking to surrounding enviroment by experiment, effectively can also control foundation settlement deformation, reduce maximum Super-void Water Pressure force value, thus improve bearing capacity of foundation soil.
Summary of the invention
The purpose of this utility model there are provided a kind of porose pile tube of New PTC type helical form for deep soft soil treatment, some circular holes are arranged to this pile tube, form pile tube with holes, pore water is enable to enter pile tube inner chamber by stake holes, this makes full use of the polywater effect of pile tube cavity, thus reduces excess pore water pressure maximum value.
The utility model is achieved like this, it comprises cylindrical tube pile lining, hole two parts, it is characterized in that the circular hole opening three distributions in equilateral triangle at cylindrical tube pile lining sustained height, then by opened three hole integral-rotations 60
oafterwards along the perforate again of stake length direction 10 times of apertures place, have some holes distributed in the shape of a spiral on pile tube wall from top to bottom according to this perforate mode.
Technique effect of the present utility model is: in the construction period, and because pile tube soil compaction effect creates Super-void Water Pressure, in soil, Free water can enter in pile tube; In the construction intermittent phase, under acting by external hydrostatic pressure, along with the dissipation of Super-void Water Pressure, in soil, Free water also can enter in hole of post.If run into mucky soil in construction, mud flows in pile tube by stake holes; If water is many in hole, then water extraction way can be taked to be got rid of; Along with water level in borehole reduces, in soil, Free water can be infiltrated in pile tube again, and make the water content of soil be able to further reduction, soil classifiction is improved, and bearing capacity of foundation soil strengthens; Effectively can reduce adjacent stake soil compaction effect during tube pile construction with holes, cleaning ambient, pile tube with holes also has power saving advantages.

In the drawings, 1, cylindrical tube pile lining; 2, helical form stake holes.In figure mono-, three, solid line representative in circular hole place is in cutaway section perforate herein; Represented by dotted arrows cross section is non-perforate herein, but in its lower certain distance perforate.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, PTC type cylindrical tube pile lining 1 sustained height opens three circular holes, and hole is equilateral triangle distribution, then rotates 60 by overall for opened three holes along the long certain distance of stake
oafter perforate again, so circulate, have some stake holes 2 distributed in the shape of a spiral on pile tube wall from top to bottom according to this perforate mode, between hole, the diameter in interval and hole is according to engine request arrangement, and adopts static pressure pile-sinking mode to construct.In construction, in soil, Free water flows in the cavity of circular pile tube by several holes on cylindrical tube pile lining, and then the mud in cavity and water are extracted out by practical pump, reduce excess pore water pressure maximum value, thus decrease the impact of effect of driving pile.
