Description
Technical field
The utility model relates to the realm of building construction, and specifically, the utility model relates to a kind of concrete precast pile.
Background technology
Along with the fast development of Chinese national economy, deepening continuously of urbanization process, city size is increasing.Increasing of Chinese Urbanization's population, cause urban land amount increasing, urban land supply is more and more nervous, in order to save soil, raising the land utilization efficiency, urban architecture structure generally develops towards high-rise super high rise structure, and the requirement of building structure to basis is also more and more higher, require that basic material has high-bearing capacity, good mechanical property.Meanwhile, the requirement carrying out foundation construction in city is more and more higher, not only requires high cost performance requirement, and the environmental requirement of pile-formation process construction is also more and more higher.
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, has buried hidden danger to the basis of building, for the problems referred to above, those skilled in the art need badly provides a kind of new technical scheme to solve the problems referred to above.
Utility model content
In order to solve the problem of prior art, the utility model provides a kind of concrete precast pile, not only constructability, ensures stability and the fastness of pile body simultaneously.
The utility model patent provides a kind of concrete precast pile, comprise pile body, 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 pile body has multiple helical blade, described helical blade extends spirally along the length direction of described pile body, and described rod iron has multiple spiral muscle groove, the center of described rod iron is fixed with the head of warhead shape.
Preferably, described helical blade is single track helical blade.
Preferably, each helical blade is along change uniform of the length direction of pile body.
Preferably, described helical blade is located at the below of described pile body.
Preferably, described helical blade is 3.
Preferably, described rod iron surface has the frosted layer for increasing frictional force.
Preferably, the material of described pile body is corrosion resistant metal.
Preferably, the material of described pile body is nonmetals.
The beneficial effect that the technical scheme that the utility model provides is brought is: the utility model by connecting pile top and rod iron successively below pile body, on pile body, be provided with helical blade and on rod iron, be provided with muscle groove and head simultaneously, 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, shorten the construction period, avoid the destruction to job site environment, effectively improve pile sinking efficiency, and avoid soil compaction effect, make pile body firmer, the utility model effectively can increase bearing capacity and the stability of pile body, has that construction is simple, speed fast, reliable in quality, bearing capacity high.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model patent, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the concrete precast pile that the utility model provides.
[in figure Reference numeral]:
10. pile body, 20. pile tops, 30. rod irons, 40. helical blades, 50. muscle grooves, 60. heads.
Detailed description of the invention
For making content of the present utility model clearly understandable, below in conjunction with Figure of description, content of the present utility model is described further.Certain the utility model is not limited to this specific embodiment, and the general replacement known by those skilled in the art is also encompassed in protection domain of the present utility model.Secondly, the utility model detailed statement that utilized schematic diagram to carry out, when describing the utility model example in detail, for convenience of explanation, schematic diagram, should in this, as to restriction of the present utility model not according to general ratio partial enlargement.
Above-mentioned and other technical characteristic and beneficial effect, will in conjunction with the embodiments and accompanying drawing static pressure pipe pile of the present utility model is described in detail.As shown in the figure, Fig. 1 is the structural representation of the concrete precast pile that the utility model provides.
