Abstract
A two-directional non-through perforated tubular pile for processing a deep soft foundation comprises a tubular pile wall and holes, wherein four columns of holes are uniformly arranged on the tubular pile wall, and holes of the opposite two columns are alternately distributed in the vertical direction; since the tubular pile wall is provided with the holes, the excess pore pressure is produced because of the soil squeezing effect of the tubular pile, water in the diagram enters the tubular pile through the holes, and the water accumulation effect of the cavity of the tubular pile is adequately utilized; the moisture content is reduced, the shear resistance of the soil is improved, and the carrying capacity of the foundation is improved; and meanwhile, the two-directional non-through perforated tubular pile has the advantages that the soil squeezing effect on the adjacent pile can be effectively reduced, a clean environment is realized, and energy can be saved.
Description
Technical field
The utility model relates to a kind of porose pile tube, relates in particular to a kind of two-way not through porose pile tube for deep soft soil treatment.
Background technology
The pile tube of at present site construction employing all is the atresia pile tube, but this pile tube can produce soil compaction effect and excess pore water pressure at work progress, very easily cause the differential settlement in house, the cracking of underground utilities, adjacent stake skew, even produce broken pile, for speedway, railway, the soft foundation that airport etc. are deep, controlling its distortion, particularly to control its settlement amount after construction be to have great significance; Therefore must produce as much as possible more settling amount in the construction period, want to produce as much as possible more settling amount in the construction period, the pore water in the soil is discharged as much as possible, reduce water content in the soil, so just can reduce the settling amount behind the worker, thereby reach the purpose of control sedimentation and deformation.
Summary of the invention
The purpose of this utility model has been to provide a kind of two-way not through porose pile tube for deep soft soil treatment, and it can reduce the minimizing of excess pore water pressure and its resolution time.
The utility model is achieved like this, a kind of two-way not through porose pile tube for deep soft soil treatment, it comprises pile tube wall and hole, it is characterized in that evenly being provided with on the pile tube wall four row holes, the hole in the vertical direction that wherein relatively lists is staggered.
Technique effect of the present utility model is: the utility model is because the pile tube wall is provided with the hole, because the pile tube soil compaction effect has produced excess pore water pressure, the water among the figure can enter in the pile tube by the hole, takes full advantage of the polywater effect of pile tube cavity; Native water content is reduced, improve the shear strength of soil, the supporting capacity of ground; Simultaneously it can effectively reduce the soil compaction effect to adjacent stake when construction, cleaning ambient, the advantage such as energy-conservation.
Description of drawings
Fig. 1 is the axonometric drawings such as structure of the present utility model.
Fig. 2 is the structural representation of a vertical tangent plane of the present utility model.
Fig. 3 is the structural representation of another vertical tangent plane of the present utility model.
In the drawings, 1, pile tube wall 2, hole.
The specific embodiment
As shown in Figure 1, 2, 3, the utility model is achieved like this, it comprises pile tube wall 1 and hole 2, evenly is provided with four row holes 2 on the pile tube wall 1, hole 2 in the vertical directions that wherein relatively list are staggered; In the construction period, the pile tube soil compaction effect has produced excess pore water pressure, and water in soil can enter in the tube chamber by hole 2; In the construction intermittent phase, under acting by external hydrostatic pressure, along with the dissipation of Super-void Water Pressure, Free water also can enter in the hole of post in the soil, if in construction, run into mucky soil, mud can flow into tube chamber by hole 2, if water is more in the tube chamber, can draw water to reduce water level, Free water can be infiltrated in the tube chamber again in the soil, native water content is reduced, improve the shear strength of soil, the supporting capacity of ground; Simultaneously it can effectively reduce the soil compaction effect to adjacent stake when construction, cleaning ambient, the advantage such as energy-conservation.
