Description
Technical field
The utility model relates to a kind of friction that can either effectively expand between preformed pile and ground soil property, improve the bearing capacity of preformed pile, while can conveniently completing the pile extension of preformed pile again, realize the waste residue that between preformed pile and ground, grouting under pressure and waste residue are filled and fill the strong foundation pile of superelevation, belong to prefabricated pile foundation and manufacture field.
Background technology
CN101058979A, title " a kind of construction method of pulling-resistant and pressure-resistant slip casting preformed pile ", is characterized in that the construction method of pulling-resistant and pressure-resistant slip casting preformed pile is realized by following steps: one, hole downwards on the basal layer of building according to the design elevation of stake and aperture; Two, after pore-forming in hole under enter steel pipe with injected hole or plastic pipe, the position of steel pipe or plastic pipe is placed in the middle in hole; Three, reinforcing bar or reinforcing cage is entered under in the hole outside steel pipe or plastic pipe; Four, sand or rubble is entered under in the space between the outer wall and hole wall of steel pipe or plastic pipe; Five, the Grouting Pipe with grouting stop-valve is entered under in steel pipe or plastic pipe; Six, start grouting pump and start slip casting in stake holes; Seven, after pile, steel pipe or plastic pipe be respectively and be effectively connected between the basal layer of reinforcing bar or reinforcing cage and building and carry out envelope stake waterproofing work.This patent is actual is a kind of Grouting, its weak point: one is that construction speed is slow, and time-consuming, stake cost processed is high; Two is to pull out and concrete centrifugal forming owing to cannot realize haling of reinforcing cage between the reinforcing cage in Grouting and concrete, and the compactness of therefore shaping concrete precast pile is low, bearing capacity is well below haling preformed pile.
Utility model content
Purpose of design: avoid the weak point in background technology, design a kind of friction that can either effectively expand between preformed pile and ground soil property, improve the bearing capacity of preformed pile, while can conveniently completing the pile extension of preformed pile again, realize the waste residue that between preformed pile and ground, grouting under pressure and waste residue are filled and fill the strong foundation pile of superelevation.
Design scheme: in order to realize above-mentioned purpose of design.1, during pile foundation boring, adopting the reaming bit boring adapting to geological structure layer material according to geology techonosphere material, and expand the design of one or more annular grooves in the boring of different geological stratification reaming bits, is one of technical characteristic of the present utility model.The object done like this is: because waste residue inserts is building debris, slag waste material, slag, metal waste residue etc., when it is along precast pile pressure pile datum hole, the pressure of its press-in is more than tens tons, therefore between pile body and geological materials, surrounding forms dense packing effect layer, this packed layer not only forms hood type forced friction to pile body, and fill the annular boss that formed again geological stratification define support, particularly for sandy soils, soft mud, fill out extra large layer and form strong support, drastically increase the stability of pile foundation geology periphery.2, being longitudinally provided with the design of erectting Grouting Pipe in preformed pile, is technical characteristic two of the present utility model.The object done like this is: when the slip casting preformed pile of the application is positioned at pile foundation hole, high pressure concrete slurry is by erectting Grouting Pipe note bottom port and to inject at the bottom of pile foundation hole and upwards bursting and become muddy when a thaw sets in slip casting along prefabricated pile lining after ground compacting bottom slurry pile foundation hole, when the pressure of slip casting of bursting and become muddy when a thaw sets in reaches the pressure of high-pressure slip-casting, frost boiling slip casting is in halted state automatically, preformed pile slip casting portion of upwards bursting and become muddy when a thaw sets in forms compactness high preformed pile foundation bearing head, drastically increases the bearing capacity of preformed pile.3, in prefabricated pile of multi-segments, the below of the grout outlet of first segment preformed pile (a bottom joint preformed pile) lower surface setting Grouting Pipe is provided with the design of peviform frost boiling dish, is the utility model technical characteristic three.The object done like this is: peviform frost boiling dish is fixed on first segment preformed pile lower surface and peviform frost boiling dish rim and the lower surface of first segment preformed pile are spacing when coordinating, it both can prevent the soil in pile foundation hole or sand blocking from erectting Grouting Pipe grout outlet, can force again and erect Grouting Pipe grout outlet high pressure spray and go out slurry and rout up along peviform frost boiling dish and turn over, reach the formation that the compacting of first segment preformed pile bottom ground and high density, high strength carry pile crown.
Technical scheme: the strong foundation pile of superelevation filled by a kind of waste residue, different geological stratifications in pile foundation hole, expand and have one or more annular grooves, more piece slip casting preformed pile is positioned at pile foundation hole, waste residue packed layer is positioned at precast pile surrounding and groove, and high pressure concrete slurry exports and discharges preformed pile bottom and surrounding by erectting Grouting Pipe lower end and form expanded head pile head and bag stake pile body wall.
The utility model is compared with background technology, one is started concrete to hale preformed pile and utilize Grouting stake holes, realize concrete and hale highly reliable, the undamaged location of preformed pile, namely effectively expand the friction of haling between concrete precast pile and ground soil property, greatly improve again the single bearing capacity haling concrete precast pile; Two be can complete the pile extension of preformed pile quickly and easily while, not only makes to hale concrete precast pile periphery pile foundation soil property compactness and increase, and the concrete density that high-pressure slip-casting is formed is large, intensity is high; Three is utilize waste residue to fill, and has both improve the stability of pile foundation surrounding geology state, has reached making full use of waste residue again, reached the object of environmental protection, material-saving.
