COUNTERLANDSLIDE STRUCTURE TO PROTECT UNDERGROUND PIPE- LINES Russian patent published in 2002 - IPC

FIELD: construction industry. SUBSTANCE: counterlandslide structure to protect underground pipe-lines located on landslide slope includes cutting member located in vertex of flow-around angle. Characteristic feature of proposed structure lies in provision of cutting member with turning mechanism manufactured in the form of rings of the type of bearings put on pipe-line and carrying metal rods on which cutting member is placed and leans-to mounted for movement of cutting member depending on direction of motion of landslide mass. EFFECT: reduced construction and operational expenses and enhanced functional reliability of structure thanks to capability of turning cutting member to counter sliding ground. 1 dwg
