Problems solved by technology
[0003] At present, the garages set up in waterfront scenic spots and leisure areas are generally underground garages. When the groundwater level is shallow, the buoyancy on the box foundation will have an adverse effect on its stability. A series of uplift piles are set at the bottom to enhance stability, and the existing piles are slightly insufficient in pullout resistance

The invention discloses a steel pipe special-shaped uplift pile. The steel pipe special-shaped uplift pile comprises a pile body, a pile cap arranged at the upper end of the pile body, a pile tip arranged at the lower end of the pile body and a spiral rib plate which is arranged on the outer circular surface of the pile body and extends to the pile tip from the pile cap, wherein the spiral rib plate is of a spiral structure, and the pile body is a circular steel pipe. The steel pipe special-shaped uplift pile is light in dead weight, and additional stress borne by soil below the bottom of thepile can be reduced, so that settlement deformation of the soil is reduced, and normal use of a building (structure) is guaranteed; and under the same condition, the pile side resistance can be increased after the spiral rib plate is arranged on the smooth pile wall, so that the bearing capacity of the pile is improved. The invention provides a construction method of the steel pipe special-shapeduplift pile.
Description
technical field [0001] The invention belongs to the technical field of building construction. Specifically, the invention relates to a steel pipe special-shaped uplift pile and a construction method thereof. Background technique [0002] At present, as a kind of deep foundation, pile foundation is widely used. Commonly used piles can be divided into reinforced concrete piles, steel pipe piles, etc. according to their materials; according to the stress state of the load, they can be divided into two categories: compression piles and uplift piles. [0003] At present, the garages set up in waterfront scenic spots and leisure areas are generally underground garages. When the groundwater level is shallow, the buoyancy on the box foundation will have an adverse effect on its stability. A series of uplift piles are set at the bottom to enhance stability, and the existing piles are slightly insufficient in uplift resistance. Contents of the invention [0004] The present invent...
