Abstract
The utility model relates to a conical tubular pile with starlike perforated holes. The conical tubular pile comprises a conical tubular pile body and starlike perforated holes. The conical tubular pile is characterized in that the pile wall of the conical tubular pile is provided with a plurality of starlike perforated holes from top to bottom. The conical tubular pile has the technical effects that if many water is in the starlike perforated holes, the water can be drained by using a pumping way; along with the decrease of water levels in the holes, free water in soil penetrates into the conical tubular pile, so that the water content of the soil is further decreased, the shearing strength of the soil is improved, and the bearing capacity of foundation soil is reinforced; when the conical tubular pile with the starlike perforated holes is under construction, the compacting effect of adjacent piles can be effectively reduced, the environment is clean; and the conical tubular pile with the starlike perforated holes has the advantage of energy conservation.
Description
Technical field
The utility model relates to a kind of conical pipe pile, relates in particular to a kind of starlike to the bore conical pile tube.
Background technology
When at present existing conical pipe pile was constructed, particularly the hammer piling mode produced soil compaction effect and excess pore water pressure, very easily caused adjacent stake skew, even broken pile.PTC type conical pipe pile 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 conical pipe pile 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 able to reduce, and reach the purpose of control sedimentation and deformation and settlement amount after construction.
Summary of the invention
It is a kind of starlike to the bore conical pile tube that the purpose of the utility model is to provide, and this conical pipe pile is provided with some starlikely perforation formed conical pipe pile with holes, the soil body side friction of polywater effect that makes full use of the conical pipe pile cavity and performance conical pipe pile side.
The utility model realizes like this, and it comprises conical pipe pile, starlike to perforation, and the pile lining that it is characterized in that conical pipe pile has from top to bottom that several are starlike to perforation.
The technique effect of the utility model is: in the construction period; Because conical pipe pile own characteristic; The little end of diameter helps bringing into play a side friction of the side soil body down, and the soil compaction effect of conical pipe pile also can suitably reduce simultaneously; Because pile driving process can produce the excess pore water pressure, Free water can get in the conical pipe pile in the soil on the other hand; In the construction intermittent phase, under the hydrostatic pressure effect, along with the dissipation that excess pore water is pressed, Free water also can get in the conical pipe pile hole in the soil.If run into mucky soil in the construction, mud can flow in the conical pipe pile perforation through starlike; 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 conical pipe pile 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 conical pipe pile with holes construction, cleaning ambient has starlike the bore conical pile tube also to be had energy-conservation advantage.

Fig. 3 is the sectional drawing of the utility model D-D, E-E, F-F.
The specific embodiment
Like Fig. 1, Fig. 2, shown in Figure 3, the pile lining of PTC type conical pipe pile 1 has from top to bottom that several are starlike to boring a hole 2, and is starlike between the perforation 1 meter at interval, and the diameter in hole is according to the engine request arrangement, and adopts the static pressure pile-sinking mode to construct.In the construction, Free water is through in several the starlike cavitys to perforation inflow conical pipe pile on the conical pipe pile lining in the soil, and practical then pump is extracted mud in the cavity and water out, has reduced conical pipe pile water content on every side, strengthens bearing capacity of foundation soil.
