PIPELINE WEIGHTING DEVICE Russian patent published in 2004 - IPC

FIELD: building industry, particularly for pipeline ballasting. SUBSTANCE: pipeline weighting device has two balance weights connected by flexible bridges and arranged symmetrically about pipeline. Flexible bridges are applied to pipeline surface. Flat bridge walls facing pipeline contact with pipeline. Hinges are fixed to front device surfaces below center of gravity thereof. Flexible bridges are connected to open hinge parts. Balance weights have cross section with the form of obtuse-angled triangle in plane transversal to pipeline. Triangle obtuse angle is more than 100 deg, triangle side opposite to obtuse angle face trench slope. Curvilinear hinges for flexible bridges connection are arranged into slots open from pipeline sides at level not exceeding horizontal axial pipeline plane level. Slot depths are greater than open part length of each hinge. EFFECT: enhanced pipeline stability into watered trench during expulsive force appearance, extended range of technical means. 2 cl, 1 dwg _
