Description
Technical field
The utility model belongs to building pile foundation engineering technical field, and in particular to a kind of band edge of a wing variable cross-section prefabricated pile, should
Structure can effectively improve the resistance to compression of stake in all kinds soft soil foundation, anti-pulling capacity.
Background technology
With continuing to develop for China's infrastructure construction, increasing construction-engineering project is built, many works
Journey haves no alternative but build on the bad soft stratum of the geological conditions such as recent fill, silt soil.Weak soil class stratigraphic compression is high, aqueous
Amount is big, and foundation bearing capacity and shearing strength are all very low, carried out on this kind of ground engineering construction easily occur it is larger
Differential settlement, causes structural instability to destroy.At present, improve the strength and stability of soft soil foundation, reduce architecture basics not
Homogeneous deformation, improves the integrated carrying level of ground, is basic demand of all kinds of construction projects in Soft Ground.Due to
Traditional prefabricated pile surface based on friction pile design is smooth, therefore in soft soil foundation, pile side friction improves little, it is impossible to
Reach the requirement of basement process.Therefore, for the feature of all kinds of soft soil foundations, high new of a kind of resistance to compression, anti-pulling capacity is studied
Type stake come carry out unfavorable geology ground treatment have be of great significance.
The content of the invention
The technical problems to be solved in the utility model is：A kind of band edge of a wing variable cross-section prefabricated pile is provided, can effectively be carried
Resistance to compression, the anti-pulling capacity of stake in all kinds soft soil foundation high.
Technical solution adopted in the utility model is：A kind of band edge of a wing variable cross-section prefabricated pile, it is by top pile body, overflow slurry
Hole, the edge of a wing long, short limb edge, bottom pile body, netted fin and pile top composition, it is characterised in that described top pile body is hollow
Variable cross-section cylinder, small bore pile body is provided with multigroup extravasating hole, and heavy in section pile body side wall is provided with the edge of a wing long；Described bottom stake
Body is hollow cylinder, and pile body outer surface is provided with netted fin, and pile body side wall is provided with short limb edge；The described edge of a wing long and short limb
Edge is constituted by the rectangular pyramid of quadrangular and outer end, and 30 ° are with pile body angle.
Construction usage method of the present utility model is：A kind of band edge of a wing variable cross-section prefabricated pile, during construction, using stake machine by band
Edge of a wing variable cross-section prefabricated pile slowly squeezes into designed elevation in ground, and the perpendicularity of pile body is no more than 1.5% during controlling to squeeze into；
After edge of a wing variable cross-section prefabricated pile is squeezed into Foundation Design absolute altitude, a machine is removed, by high-pressure slip-casting equipment and the hollow bulb of stake top
Position is connected and carries out grouting operation, slurries is entered inside pile body, and slurries are all full of stake is exuded to from extravasating hole behind pile body inside
Soft soil layer, is combined as a whole after hardening with the variable cross-section pile body on top and the bottom on the edge of a wing, completes construction.
Operation principle of the present utility model is：A kind of band edge of a wing variable cross-section prefabricated pile, pile body is increased by setting the edge of a wing
With the contact area of surrounding soil, the top pile body edge of a wing is more than the bottom pile body edge of a wing, the variable cross-section of pile body is capable of achieving, so as to improve
Pile side friction；Top pile body can inject slurries for the hollow and multigroup extravasating hole of setting between stake and soil, and formation Seed harvest makes
Pile body is connected more firm with surrounding soil, so as to be reinforced to stake week ground, improves pile body bearing capacity；Bottom stake
Body is closely interlocked by netted fin with the soil body, makes pile body stress harmonious with earth stress, so as to increased stake
The firm performance on basis, compressive property and extraction-resistant behavior, so as to improve the resistance to compression of stake in soft soil foundation, resistance to plucking bearing capacity.
The beneficial effects of the utility model are：A kind of band edge of a wing variable cross-section prefabricated pile, pile body side wall is provided with the edge of a wing long and short
The edge of a wing, 30 ° are with pile body angle, relatively easily can be squeezed into ground, and the edge of a wing long and short limb edge all can and surrounding
Soil layer produces synergy, the physico-mechanical properties of pile peripheral earth can be effectively improved, so as to improve pile body bearing capacity；Top
Pile body can inject slurries for the hollow and multigroup extravasating hole of setting between stake and soil, and formation Seed harvest makes pile body and surrounding soil
Connection is more firm, so as to be reinforced to stake week ground, improves pile body bearing capacity；Extravasating hole is arranged on small bore stake
With, because heavy in section pile body has more a part, therefore extravasating hole can will not effectively prevent extravasating hole from blocking with native directly contact,
And the contact area of pile body and slurries is increased, engineering practicability is strong；Bottom pile body is closely engaged by netted fin with the soil body
Together, make pile body stress harmonious with earth stress, so as to increased firm performance, compressive property and the resistance to plucking of pile foundation
Performance, so as to improve the resistance to compression of stake in soft soil foundation, resistance to plucking bearing capacity.
