Utility model content
In order to solve the problem of prior art, the utility model provides a kind of resistance to plucking Prefabricated hollow pile, 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 resistance to plucking Prefabricated hollow pile, comprise pile body, expanding end and pile top, described expanding end is located at the below of described pile body, its diameter is greater than the diameter of described pile body, described pile body and expanding end have the hollow structure for filling wadding weft variation, the hollow structure of described pile body has the wave shape groove for increasing frictional force, and the external surface of described expanding end has spirality convex rib.
Preferably, described hollow structure is the up-small and down-big Rotary-table structure of cross section cylindrical structure unanimous between the higher and lower levels or cross section.
Preferably, described wave shape groove is distributed in the top of described pile body.
Preferably, described wave shape groove accounts for 1/2nd of described pile body.
Preferably, described wave shape groove is covered with the hollow structure of described pile body.
Preferably, described wave shape groove is arranged at the spaced surface of the hollow structure of described pile body.
Preferably, the top of described pile body is provided with end plate.
The beneficial effect that the technical scheme that the utility model provides is brought is: be provided with the expanding end and spirality convex rib that are 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 expanding end 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 hollow structure with wave shape groove considerably increases the conjugation 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, be applicable to promoting the use of.
