Cast-in-place reinforced concrete uplift pile and construction method

The embodiment of the invention discloses a cast-in-place reinforced concrete uplift pile and a construction method. The cast-in-place reinforced concrete uplift pile comprises a reinforced concrete pile body, the stress absorbing layer is arranged at the top of the reinforced concrete pile; the stress dissipation layer is arranged on the stress absorption layer; the sleeve assembly is arranged on the outer side of part of the stress absorption layer and the stress dissipation layer in a sleeving mode. The cast-in-place reinforced concrete uplift pile provided by the embodiment of the invention comprises the reinforced concrete pile, the stress absorption layer, the stress dissipation layer and the sleeve assembly, the adverse effect of pile top pressure can be eliminated through the arrangement of the stress absorption layer and the stress dissipation layer, the uplift pile is purely pulled, the adverse effect on foundation settlement is reduced, and the service life of the uplift pile is prolonged.
