Description
Technical field
The utility model relates to pile foundation construction field, is specifically related to a kind of formed compound pile of stake being connected by many coaxial lines.
Background technology
There is following feature in the pile foundation that China's the realm of building construction is used at present: vertical force, horizontal force that the top pile being connected with building in pile foundation is subject to are larger, so need the stake that rigidity is large, anti-bending strength is high to do top stake; And bottom stake due to go deep into the soil body and and the soil body between the frictional force that produces larger, relative with soil body build-in firm, the diameter of bottom stake, rigidity, bearing capacity, anti-bending strength comparable top stake are little.
But in current Design of Foundation, according to the weight of construction of structures, to calculate the bearing capacity of pile foundation, get maximum weighted parameter and come to select diameter to pile foundation, in whole pile foundation, all use the pile tube of same diameter, cause the increase of pile foundation cost and the waste of resource.If but in order to save cost, dwindled the diameter of selected pile tube, if select the pile tube that does not reach maximum weighted parameter to form pile foundation, could reduce the safety of pile foundation.
Utility model content
Technical problem to be solved in the utility model is to make up the deficiency existing in current pile foundation construction process, and a kind of compound pile is provided, and can improve safety and the bearing capacity of pile foundation, can reduce again the cost of pile foundation.
For addressing the above problem, the utility model provides a kind of compound pile, includes the stake that many upper and lower coaxial lines connect, and it is characterized in that: wherein a pile of topmost is pile tube, and a pile of foot is ring stake.Described pile tube is the Compression Members Made of Reinforced Concrete with Circular Section preformed pile of steel pipe pile or reinforced concrete pipe pile or other types, and described pile tube welds with being connected to of ring stake or flange bolt is connected.
On pile body due to the ring stake in this combining structure, there is annular projection, thereby the contact area of ring stake and the soil body produces larger frictional force with the soil body more greatly, according to the difference of the construction of structures of institute's load, the pile body diameter of selected ring stake is also different, and the pile body diameter of ring stake is not necessarily identical with the pile body diameter of pile tube.The ring stake of same pile body diameter can provide the bearing capacity larger than pile tube.Thereby and provide the pile body diameter of the ring stake of same bearing capacity littlely to save material, reduced cost than the pile body diameter of pile tube.
Preferably, in compound pile, the junction diameter of described tubular pile body and ring stake is identical, and the diameter of ring stake pile extension one end is identical with pile body diameter, and ring stake and soil body build-in are firm.The formed pile foundation of this compound pile can provide than all using the larger bearing capacity of the formed pile foundation of same diameter pile tube, thus the safety that has improved pile foundation.
Preferably the bottom of described ring stake is provided with expansion head, pile tube is connected with the top of ring stake, the junction diameter of tubular pile body and ring stake is identical, and ring stake is because so bottom expansion head can provide larger end bearing power, the formed pile foundation of this compound pile can provide than the larger bearing capacity of same diameter pile foundation in upper a kind of situation, and safety is better.
Preferably the top of described ring stake is provided with expansion head, ring stake is connected with pile tube via the expansion head at top, the junction diameter of tubular pile body and ring stake is identical, in this case, the pile body diameter of ring stake is less than the pile body diameter of connected pile tube, so the formed pile foundation of this compound pile can provide with all by the same bearing capacity of the formed pile foundation of same diameter pile tube, and saved material, reduced cost.
Preferably the two ends of described ring stake are equipped with expansion head, stake is connected pile tube with ring, the junction diameter of tubular pile body and ring stake is identical, the pile body diameter of ring stake is less than the pile body diameter of pile tube, the ring stake that this two ends are equipped with expansion head can provide than identical pile body diameter and only have top to expand the larger end bearing power of ring stake of head, and the formed pile foundation of compound pile in this case can provide the larger bearing capacity of pile foundation than the identical pile body diameter in upper a kind of situation.
Described in above situation, compound pile of the present utility model is owing to having used ring stake, when the bearing capacity that provides when ring stake is identical with pile tube, the pile body diameter of this ring stake is less than the pile body diameter of this pile tube, so can effectively save material, reduce costs.And the ring stake of identical pile body diameter is larger than the bearing capacity of pile tube, make the formed pile foundation safety of whole compound pile higher.The utility model can make up the deficiency existing in current pile foundation construction process effectively.
