PLANT AND METHOD OF PIPELINE BURIAL Russian patent published in 1998 - IPC

FIELD: pipeline burial. SUBSTANCE: plant has hauling unit, system of hoist with side walls, guide projections located at some distance from one another and located in front of hoist system. At least one projection has at least one rotor system of feeder. Plant also has separator and conveyer. In realization of the claimed method of pipeline burial with pipeline lying in excavated trench, spoil is filled to trench one side and hauling unit is continuously moved along side of trench where spoil is located. Hoist position is regulated by turning. Guide projections of hoist assist in loading of hoist system. The latter is swinging and rotor feeder assists in moving of spoil to hoist. Further on, spoil is separated into fine-grained and coarse-grained materials. The latter is laid near the trench, behind the hoist, while fine-grained material is hauled to trench. EFFECT: highly efficient gathering and loading of ground for processing into burial material. 2 cl, 25 dwg
