Pipeline Anchor Apparatus

摘要

A pipeline anchor apparatus is disclosed. The pipeline anchor apparatus provides left and right anchor units connected by a tie-down strap made of heavy-duty polyester or nylon webbing. The strap prevents the pipeline from floating in wet conditions. By flexibly conforming to the surface of the pipeline, the tie-down strap prevents denting of the pipeline which weakens the pipeline, contributing to pipeline bending. Each anchor unit provides an helix anchor attached to an anchor rod that is buried deep in the soil. The anchor rod is connected to an extension rod by means of a lower coupling. A tie-down bracket having a tubular body and a sleeve is carried by the extension rod. Each end of the tie-down strap is attached to the sleeve of a tie-down bracket of an anchor unit. The tie-down brackets may pivot about the extension rod to lessen stress as water forces the pipeline upwardly, against the tie-down strap. The sleeve of the tie-down bracket is radially outwardly from the axis of the tubular body. As a result, an upward force on the sleeve may force the tie-down bracket and extension rod away from the pipeline, thereby protecting the pipeline from denting and bending.
