WATERPROOF UPLIFT-RESISTANT PILE AND CONSTRUCTION METHOD

WIPO Patent Application WO/2024/001680

A1

Disclosed in the present invention are a waterproof uplift-resistant pile and a construction method, which pile and method relate to the technical field of pile foundation construction. The waterproof uplift-resistant pile comprises a steel bar framework, wherein the top end of the steel bar framework is provided with a plurality of bent steel bars having end portions away from an axis of the steel bar framework, the steel bar framework below the bent steel bars is sleeved with a waterproof layer, a water stopping plate sleeved on the steel bar framework is arranged between the waterproof layer and the bent steel bars, and a concave face facing the waterproof layer is arranged on the water stopping plate to guide water seepage away from the bent steel bars and the steel bar framework; and a foundation base plate which wraps the water stopping plate and the bent steel bars is arranged above the waterproof layer. Targeting the problem of it being difficult for the waterproofness and corrosion resistance of current uplift-resistant piles to satisfy requirements, the water stopping plate and the waterproof layer are arranged on the steel bar framework, and water seepage from below the waterproof layer is guided by utilizing the concave face structure of the water stopping plate, so as to prevent the water seepage from surging up to a bent steel bar position and guide the water seepage to flow to a position away from the steel bar framework, such that the water content at a contact position of the steel bar framework is reduced, and the waterproof performance is improved, thereby enhancing the corrosion resistance.
