METHOD FOR PRODUCTION OF CONCRETE WEIGHT COATED PIPE WITH CABLE TRUNKING Russian patent published in 2018 - IPC F16L9/14 

FIELD: production of pipes.

SUBSTANCE: invention relates to production of pipes with concrete cover used for laying pipelines on sea shelves, river crossings, in flooded or swamplands, as well as for underground or above-ground laying of pipelines in ever-frozen, seasonally frozen and weak soils, for the purpose of ballasting and/or protection of pipelines against mechanical damage. Pipe is mounted on integration bench, reinforcing structure is placed on it, assembled structure is placed in concrete form with a projection along its entire formlining. Then concrete mixture is pumped into the space between the pipe and the concrete form. After curing the concrete pipe is removed from the concrete form.

EFFECT: technical task is to create method for production of concrete weight coated pipe with cable trunking, which is used in manufacture of sections of a new pipeline in plant conditions, has a high reliability associated with the placement of cable trunking in the thickness of concrete cover of pipeline, and also – versatility.
