Abstract
The utility model relates to a PTC-type tubular pile with holes for deep soft foundation treatment, comprising a cylindrical tubular pile wall and perforated holes. The PTC-type tubular pile with the holes is characterized in that the cylindrical tubular pile wall is provided with a plurality of perforated holes from top to bottom and has the technical effect that in the construction period, excess-pore water pressure is generated due to the soil extruding effect of the tubular pile, and free water in the soil can enter the tubular pile holes; in the intermission of the construction, the free water in the soil also can enter the tubular pile holes with the dispersing of the excess-pore water pressure under the function of the hydrostatic pressure. If muddy soil is generated in the construction, mud can flow into the tubular pile holes through the perforated holes, and if more water is in the holes, a water pumping method can be adopted to discharge the water; along with the waterlowering in the holes, the free water in the soil can penetrate into the tubular pile again to lead the moisture content of the soil to be reduced further, the shearing strength of the soil to be improved and the bearing capacity of a foundation to be enhanced; and the tubular pile with the holes can effectively reduce the soil extruding effect of the adjacent piles, clean the environment, and also has the advantage of energy conservation.
Description
Technical field
The utility model relates to a kind of pile tube, relates in particular to a kind of PTC type pile tube with holes that deep soft foundation is handled that is used for.
Background technology
At present during the existing pipes pile driving construction, particularly the hammer piling mode produces soil compaction effect and excess pore water pressure, very easily causes adjacent stake skew, even broken pile.PTC type pile tube is used for the deep soft soil foundation treatment project, and main purpose is the distortion of control foundation settlement, improves bearing capacity of foundation soil, and pile tube self bearing capacity is not a subject matter.The main cause that the foundation settlement distortion produces is because the discharge of soil body mesopore water under the outer load effect.Concerning deep soft soil foundations such as speedway, high-speed railway, road in airport, control its foundation settlement distortion, mostly is to control its settlement amount after construction, and its settlement amount after construction is controlled in the settlement amount after construction critical field.If will produce more settling amount as far as possible in construction periods such as embankment, dykes and dams, roads, promptly produce more construction period sedimentation and deformation amount, should be with the discharge as much as possible of native mesopore water, reduce the water content of soil, then its settlement amount after construction will be reduced, and reach the purpose of control sedimentation and deformation and settlement amount after construction.
Summary of the invention
The purpose of this utility model has been to provide a kind of PTC type pile tube with holes that deep soft foundation is handled that is used for, and this pile tube is provided with some to perforation, forms pile tube with holes, makes full use of the polywater effect of pile tube cavity.
The utility model is achieved like this, it comprise the cylindrical tube pile lining, to the perforation, it is characterized in that the cylindrical tube pile lining have from top to bottom several to the perforation.
Technique effect of the present utility model is: in the construction period, because the pile tube soil compaction effect has produced the excess pore water pressure, Free water can enter in the pile tube in the soil; In the construction intermittent phase, under the hydrostatic pressure effect, along with the dissipation that excess pore water is pressed, Free water also can enter in the hole of post in the soil.If run into mucky soil in the construction, mud can be by flowing in the pile tube perforation; If water is many in the hole, then can take the mode of drawing water that it is got rid of; Along with water level in the hole reduces, Free water can be infiltrated in the pile tube again in the soil, makes the water content of soil be able to further reduction, and the shear strength of soil is improved, and bearing capacity of foundation soil strengthens; Can effectively reduce adjacent stake soil compaction effect during the ported sub pile driving construction, cleaning ambient, pile tube with holes also has energy-conservation advantage.

Fig. 3 is the horizontal cross section structural representation of the utility model.
In the drawings, 1, cylindrical tube pile lining 2, to perforation
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, PTC type cylindrical tube pile lining 1 has several from top to bottom to boring a hole 2, and to 1 meter at interval between the perforation, the diameter in hole is according to the engine request arrangement, and employing static pressure pile-sinking mode is constructed.In the construction, Free water is by in several cavitys to the circular pile tube of perforation inflow on the cylindrical tube pile lining in the soil, and practical then pump is extracted mud in the cavity and water out, has reduced cylindrical pile tube water content on every side, strengthens bearing capacity of foundation soil.
