Utility model content
In order to solve the problem of prior art, the utility model provides a kind of pull-out resistant pile foundation structure, increases the frictional force of filling out between heart concrete and pile body on the one hand, increases the frictional force of pile body and sub-surface on the other hand.
The utility model patent provides a kind of pull-out resistant pile foundation structure, comprise pile body and pile top, described pile body has the hollow structure for filling wadding weft variation, the external surface of the below of described pile body is provided with multiple annular protruding rib, the cross-sectional diameter of described annular protruding rib is greater than the diameter of described pile body, the top of described hollow structure is truncated cone-shaped structure, is cylindrical structural below it, and the aperture of described truncated cone-shaped structure is large from little change from top to bottom.
Preferably, the diameter of described annular protruding rib is greater than the diameter 5cm ~ 20cm of described pile body.
Preferably, the equal diameters of each annular protruding rib.
Preferably, the diameter of described annular protruding rib diminishes from top to bottom gradually.
Preferably, the sidewall of described truncated cone-shaped structure has the matsurface for increasing friction force.
Preferably, the sidewall of described cylindrical structural has the matsurface of increasing friction 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: be provided with the multiple annular protruding ribs being greater than pile body diameter below pile body of the present utility model, add frictional force and the breakout capacity of pile body and sub-surface, the soil layer of annular protruding rib and surrounding produces synergy, effectively can improve the physico-mechanical properties of low soil layer, and increase substantially bearing capacity and the frictional resistance of pile body; On the other hand, the aperture of the truncated cone-shaped structure of hollow structure 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, the utility model substantially increases the anchoring property between wadding weft variation, pile body and sub-surface, structure is simple, convenient and swift, is applicable to promoting the use of.
