Abstract
The utility model discloses an elastic displacement compensator which comprises a sleeve provided with a cylindrical cavity, and the sleeve is made of elastic and soft materials. Rigidity reinforced rings or spiral rigidity reinforced ribs which are coaxial with the sleeve are arranged in the sleeve. After soil is backfilled and a pavement is smoothed, the condition of inconsistent sedimentation happens to backfill of an inspection well and the periphery of the inspection well after a heavy object passes through the top of the inspection well, namely, the size of sedimentation of the backfill and a pipeline is larger than that of the inspection well. Due to the fact that the sleeve is made of the elastic materials, the sleeve plays a good role in buffering and displacement compensation, and greatly reduces the condition of stress concentration. After the heavy object passes, the pipeline is recovered under the action of springback, so the elastic displacement compensator is prevented from being damaged when the heavy object passes.
