PIPE LINE WEIGHTING MATERIAL AND METHOD OF ITS MOUNTING Russian patent published in 1996 - IPC

FIELD: assembly of pipe lines. SUBSTANCE: set of longitudinal panels interacting with filling soil are arranged in pairs on sides of pipe line and are connected by load-bearing belts laid on pipe lines. Set of rigid transverse U-shaped walls rest by their lower domes on pipe line and are engageable with longitudinal panels. Weighting material is made in form of stack whose longitudinal panels and load-bearing belts are made integral from solid flexible material and are tightly connected with transverse walls which have form of trench in cross section. For mounting the weighting material on pipe line, separated panels and walls are located on pipe line. Preliminarily stacked weighting material (wall-to-wall) is mounted on pipe line by its lower dome. Panels are separated to complete straightening by shifting the walls along pipe line. Hinged sides are located on trench berms. Adjacent weighting materials mounted on pipe line are interconnected by securing the walls with the aid of clamps. EFFECT: enhanced reliability. 6 cl, 2 dwg
