Shearing-resistant pile sleeve assembly suitable for construction under harsh conditions

The utility model discloses an anti-shear pile sleeve assembly suitable for construction under harsh conditions, which comprises a pile sleeve main body, a convex ring seat is arranged in the middle of the pile sleeve main body, the convex ring seat extends towards the outside of the sleeve to form an annular supporting seat and extends towards the inside of the sleeve to form a semi-closed interlayer, and the semi-closed interlayer divides an inner cavity of the pile sleeve main body into an upper accommodating cavity and a lower accommodating cavity. The upper end of the sinking pile is sleeved with the lower containing cavity, and the lower end of the upper sinking pile is sleeved with the upper containing cavity. The convex ring seat is arranged at the stress concentration position in the middle of the pile sleeve main body, and the thickness of the convex ring seat is obviously larger than the wall thickness of the pile sleeve main body, so that the strength of the stress concentration position is improv
