The utility model discloses an advantage is the precast pile, and the pile body quality is guaranteed, and the construction noiselessness does not have the casting, need not the maintenance, is fit for winter, remote districts, broken ground construction on water even, it is long to increase the stake through the extension rod, has reduced the requirement to the construction headroom, especially is fit for in indoor construction.
Description
Technical field
The utility model belongs to field of civil engineering, especially belongs to the pile foundation in geotechnical engineering field.
Background technology
Pile foundation is a kind of foundation pattern that field of civil engineering is commonly used, and adopts pile foundation can bear the load of superstructure, and control settlement distortion is in allowed band.Conventional pile foundation has castinplace pile and preformed pile two class.The construction method of castinplace pile routine is first adopt large type drill pore-forming in ground, then in hole, places pre-processed reinforcing cage, then concreting maintenance pile.Filling pile construction operation is more, and speed of application is slow, and quality is wayward, and often relates to mud off and spoil disposal, is unfavorable for environmental protection.In addition because the maintenance of cast-in-place pile concrete has certain restriction to temperature, therefore often cannot construct in the winter of cold.Preformed pile is generally shaping in factory process, has concrete and steel two class from material point.The construction of preformed pile has hammering and static pressure two kinds of techniques.Adopt hammer-impact construction, can produce larger noise and vibration, affect surrounding enviroment, be generally forbidding in city.Static pressure method adopts large-scale pile press, and the large-tonnage counterweight relying on self to be equipped with provides counter-force to be pressed in soil by preformed pile.Although static pressure method can not produce noise and vibration as hammering method, but because its deadweight must be greater than the ultimate bearing capacity of oil and pile interaction generation, so pile press self is very huge, walking is heavy, only be adapted at spacious smooth field construction, and be only applicable to soft soil layer.Preformed pile belongs to Squeezing Soil Pile, because it mainly obtains bearing capacity by the friction between all external surfaces of stake and the soil body, thus stake footpath is general all larger, therefore no matter be Driven Piles or static pressed pile, its soil compaction effect clearly, all need certain convalescence after construction terminates, just can reach its design bearing capacity.
The construction of above-mentioned various pile-type has certain requirement to construction plant, all to meet the current requirement of construction equipment and the traffic requirements of construction material, therefore cannot construct at narrow and small construction space, soft soil layer is then needed to anticipate, to meet the current of construction equipment, then directly cannot construct especially in water, and need matching operation cofferdam.
Summary of the invention
The purpose of this utility model is that design a kind ofly screws the piling bar crept into, and belongs to preformed pile, comprises first guide rod and extension rod and linkage.First guide rod is welded with helical blade, and helical blade can be one or multiple tracks, and the bottom of first guide rod arranges pile top, and extension rod is connected on first guide rod upper end, is connected between itself and first guide rod or between extension rod with extension rod by linkage.One screws the piling bar crept into and can not have extension rod or have many interconnective extension rods as required.
What the utility model proposes screws the piling bar crept into, and its construction capital equipment is hydraulic power head, and hydraulic power head needs to install on board a dredger can on the equipment of output hydraulic pressure or crane is first-class.During construction, be first connected at the top of hydraulic power head with first guide rod, the moment of torsion exported by unit head drives piling bar to rotate, and piling bar relies on the snap-in force of helical blade and the soil body in the process rotated, produce descending power and pierce in soil.After guide's bar drill enters the soil body, unclamp the connection of unit head and pile body, by linkage, extension rod is connected to the top of first guide rod, the same with the method for the first guide rod of construction, then extension rod part is also pierced in soil.According to design needs, said method is adopted to connect second section extension rod again and construct, until foot is covered with in whole stake design needs.
Compared with the existing technology, the utility model has the advantage of:
(1) the utility model is preformed pile, and pile body makes in factory process, and pile quality is guaranteed, and on-site construction processes is simple, without the need to maintenance, can use, greatly can shorten the construction period after construction terminates;
(2) the vaned pitch of the utility model institute is all identical, and blade pitgh is the integral multiple of pitch, can guarantee like this to the utility model proposes to screw the piling bar crept into consistent at the advance track of drilling process Leaf, reduce blade to greatest extent to the cutting disturbance of the soil body;
(3) this is suitable for the novel mode by extension rod to increase stake long, reduces the requirement to headroom of constructing, is particluarly suitable for indoor construction;
(4) the novel problem not relating to maintenance of this construction, and creep into by certain thickness frozen soil layer by screwing, be therefore applicable to the winter construction of cold district;
(5) the utility model is screwed by hydraulic power head and creeps into, noiselessness, and friction does not relate to mud off and casting, also can accomplish minimum, environmental protection to the destruction on ground;
(6) main construction equipment of the present utility model is hydraulic power head, appearance and size is little, and (diameter is generally within 0.5m, height is within 1m), hydraulic pressure is commonly used excavator and is provided, therefore low to the requirement of construction plant and road, can boundary of works area be increased by increasing extension arm, being especially applicable to the engineering that construction plant is narrow and small and builder's road is soft, even can at subaqueous work;
(7) energy that the utility model construction consumes is only diesel oil, is therefore applicable to the remote districts not having electric power.
