At present, precast concrete or piling bar have good cost performance and mechanical property, but during bore forming, there is noise pollution, and owing to being soil compaction construction, extreme influence is caused to periphery building safety and resident, adopts Static pressure pile driver construction although now a large amount of, greatly reduced construction noise low, but the destruction of soil compaction effect does not but change, bury 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 pile, not only improves bearing capacity and the stability of pile body, and construction noise is little simultaneously, avoids soil compaction effect.
The utility model patent provides a kind of concrete pile, comprise a prefabricated stake center and be positioned at the layer that thes cement solidifies of described prefabricated stake center periphery, cement grout in the hole that the described layer that thes cement solidifies is got out in soil layer in advance by cast-in-site solidifies and forms, described prefabricated stake center comprises in cylindrical pile body and to be located at below described pile body and in cylindrical stake seat, the described layer that thes cement solidifies comprises in cylindrical main part and to be positioned at below described main part and in cylindrical wide diameter portion, the diameter of described stake seat cross section is less than the diameter of described main part cross section.
Preferably, the height of described wide diameter portion is greater than the height of described stake seat.
Preferably, the lateral wall of described pile body has some projecting ring sections.
Preferably, described projecting ring section is uniformly distributed at the lateral wall of described pile body.
Preferably, the external surface of layer of theing cement solidifies described in has some convex joints.
Preferably, described prefabricated stake center is made up of concrete and precast reinforced cage.
The beneficial effect that the technical scheme that the utility model provides is brought is: the utility model by placing prefabricated stake center in the hole got out in advance, then in hole, joints cement slurries form the layer that thes cement solidifies, wherein, the bottom of stake core is provided with stake seat, below the solid layer of coagulating cement, wide diameter portion is set, substantially increase the supporting capacity of pile body, breakout capacity and stability, in the process of construction, quick construction is convenient, noise pollution is little, effectively improves pile sinking efficiency, shortens construction period, 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.
