Anchoring of pipelines
ANCHORING OF PIPELINES (EN: pipeline anchoring; DE: Ankerung von Rohrleitungen; FR: ancrage des tuyauteries; ES: anclaje de tuberias; RU: анкерное закрепление трубопроводов) is the method of the fixation of pipelines on the anchored supports; it is used for the prevention of the surfacing of pipelines, which are laid within the swamped and watered soils.
The process of conducting of the works during the anchoring of pipelines (anchoring) is performed with the help of the special machinery and equipment for the hammering, screwing, or firing of the anchors, which are the constituent elements of the anchored supports (Figure), which are plunged into the ground at the both sides of the pipeline. There embraces the anchors from the top the reinforced belt, onto which there is laid the interleaving material (brizol, wooden mats, and others), which is preventing the damage of the insulation of pipeline.
Anchored supports are constructed along the entire route of pipeline, at the equal intervals. The number of the supports and the distance between them depend on the buoyant force, which acts onto the pipeline, on the longitudinal rigidity of the pipeline, and on the carrying capacity of the supports.
