POLYMER PANEL-TYPE ANCHORING DEVICE Russian patent published in 2005 - IPC

FIELD: construction engineering; laying pipe lines in frozen and rocky soils.

SUBSTANCE: proposed device has pair of symmetrical (relative to pipe line) reservoirs filled with ballasting soil which are connected with load-bearing band and flexible load-bearing strips secured to outer longitudinal sides of rigid rectangular frames forming the framework of reservoirs; they are engageable with pipe line below its center generatrices. Device is provided with cover plate located above load-bearing band; edges of this cover plate are laid on pipe line and are connected above upper generatrix of pipe line at overlap. Transversal sizes of reservoir exceed width of trench; reservoirs are located in pits without transfer of weight of ballast to their bottom ; reservoir are made in form of boxes. Bottoms of reservoirs and load-bearing band are made from single cloth of flexible material passed under inner longitudinal sides of flat frames and secured on their outer longitudinal sides. Cover plate, load-bearing band and flexible load-bearing strips are secured in center part; angle between planes of rigid frames of reservoirs does not exceed 180 deg.

EFFECT: enhanced reliability of securing pipe line at design marks.
