Reinforcement cage for long cast-in-place pile

The utility model discloses a reinforcement cage for a long cast-in-place pile, and aims to solve the technical problems that in the prior art, a reinforcement cage is difficult to insert into a cast-in-place pile where concrete is poured, the strength of the reinforcement cage is poor, and the stress capacity required by construction cannot be met. The conical part is formed by welding a plurality of conical part main reinforcements; the cylindrical cage body is welded on the conical part; the cylindrical cage body comprises a plurality of cage body main reinforcements which are correspondingly welded on the conical part main reinforcements, a plurality of annular positioning reinforcements which are welded on the inner sides of the cage body main reinforcements, and winding reinforcements which are welded on the outer sides of the cage body main reinforcements. The reinforcement cage is good in integrity and high in rigid strength, and can meet the construction strength requirements of hoisting the reinforc
