China coast city, the preformed pile that the building such as construction industry factory building, civilian construction and bridge, power station, harbour, warehouse uses is in the process of press-in sub-surface, easily make pile body inclining or cause pile body to fracture, impaired, increase construction cost, the region that particularly soil property is comparatively hard, pile body press-in sub-surface is comparatively difficult, bury hidden danger to the basis of building, in addition, because Prefabricated hollow pile is made by centrifuging process, inwall smoother, the adhesion strength between wadding weft variation and hollow pile inwall is low, and wadding weft variation is easily pulled up.For the problems referred to above, those skilled in the art need badly provides a kind of screw-in prefabricated tubular pile, not only can increase the frictional force of filling out between heart concrete and pile body, is convenient to pile body press-in sub-surface simultaneously.
Utility model content
In order to solve the problem of prior art, the utility model provides a kind of screw-in prefabricated tubular pile, not only can increase the frictional force of filling out between heart concrete and pile body, is convenient to pile body press-in sub-surface simultaneously.
The utility model patent provides a kind of screw-in prefabricated tubular pile, comprise pile body, described pile body has the hollow structure for filling wadding weft variation, the top of described hollow structure is truncated cone-shaped structure, it is cylindrical structural below it, the aperture of described truncated cone-shaped structure is large from little change from top to bottom, the lower end of described pile body is connected with the pile top of taper type, the lower end of described pile top is provided with a rod iron, described rod iron have two spirality groovings, described grooving is provided with several cutting blades, and described cutting blade joins end to end stepped.
Preferably, described cutting blade and described grooving perpendicular.
Preferably, the sidewall of described truncated cone-shaped structure and/or cylindrical structural has the matsurface of increasing friction force.
Preferably, described rod iron surface has the frosted layer for increasing frictional force.
Preferably, the top of described pile body is provided with bearing plate.
Preferably, described truncated cone-shaped structure and the length of described cylindrical structural are than being 1:1.
The beneficial effect that the technical scheme that the utility model provides is brought is: the aperture of the truncated cone-shaped structure of the hollow structure of the utility model pile is large from little change from top to bottom, thus the conjugation added between wadding weft variation and pile body, improve the resistance to tension of wadding weft variation, on the other hand, pile top and rod iron is connected successively below pile body, even if in the region that soil property is comparatively hard, can pile body can be screwed in sub-surface when applying little pressure, expand the scope of application of preformed pile, simplify construction process, the utility model substantially increases the anchoring property between wadding weft variation and pile body, efficiently pile body can be pressed into sub-surface simultaneously, structure is simple, convenient and swift, be applicable to promoting the use of.
