description The invention discloses an accurate control device for a high-speed railway bridge pier column steel bar protective layer. According to the accurate control device, two straight skeletons are connected with two arched skeletons to form an arc-shaped limiting skeleton, and an inner straight fixing clamping plate and an outer straight fixing clamping plate and an inner arc-shaped fixing clamping plate and an outer arc-shaped clamping plate are arranged on the straight skeletons and arc-shaped skeletons correspondingly; the middle parts of the straight skeletons bend inwards correspondingly to reserve drainage grooves, and a V-shaped or U-shaped limiting groove is formed in the inner side of the limiting skeleton, and it is ensured that after the limiting skeleton is connected as a whole, anouter bridge pier column pre-embedded steel bar is enabled to be completely clamped in the limiting groove of the limiting skeleton to achieve an self-locking effect; and the pre-embedded steel bar iscorrected vertically by a
