Abstract

The invention discloses a high-strength and high-durability uplift pile. The uplift pile comprises a hollow pile body, a pile tip fixedly connected to one end of the pile body, and a plurality of projections positioned on the inner wall of the pile body; and the pile tip is provided with a thread part. Compared with uplift piles in the prior art, the high-strength and high-durability uplift pile has the following advantage: the internal of the uplift pipe is provided with the projections to increase the friction force between the pile body and a coating layer, so floatation of the pile body is reduced.

Description

technical field [0001] The invention belongs to the field of pipe piles, in particular to a high-strength and high-durability uplift-resistant pile. Background technique [0002] In areas with high groundwater levels such as coastal areas or along lakes, uplift piles are required to constrain the buoyancy of groundwater to buildings. Existing uplift piles include: bored reinforced concrete pouring piles, anchor piles and bottom expansion piles. The basic principle is: through the frictional resistance generated by the relative movement between the uplift pile body and the rock-soil layer, it is transmitted to the reinforced material (steel bar or steel strand) in the pile body, and the reinforced material and the underground buildings and structures are combined. The floor is connected to counteract the buoyancy of the building from the ground. Higher pullout resistance can be obtained by using bored piles, but the construction cost, quality and construction period are lon...
