PILE OF LANDSLIDE-PREVENTION STRUCTURES, USED ON SOFT GROUNDS Russian patent published in 1995 - IPC

FIELD: construction. SUBSTANCE: pile of landslide-prevention structures, used on soft grounds, has: pile trunk, made as square, diamond-shaped, oval in plan, prismatic or pyramidal in height; broadening, made in the form of disks-breadths of trapezoidal variable cross-section or uniform cross-section, located in symmetry to both axes of symmetry on peaks of pile body with square and diamond-shaped trunk. Broadenings are made as sector members or as truncated polyhedral prisms or as truncated polyhedral prisms of uniform cross-section. Broadenings are made as trapezoidal prisms of variable cross-section with plane of symmetry going through middle horizontal plane. In the case of oval cross-section of trunk broadenings are made of single direction and different directions in respect to cross-section of trunk. Broadenings of pyramidal piles are made with inner dimension of variable value, increasing in direction of their length from down to top together with broadening of pile trunk. Broadenings of trunk of diamond-shaped cross-section are made in the form of truncated polyhedral prismatic disks, that are located in pairs in one plane in respect to horizontal axis of symmetry and are alternated with paired disk-broadenings by steps on opposite side of axis of symmetry. In case of broadenings, that are made separately from trunk of pile, disks are made of triangular cross-section or in the form of polyhedral prisms of reinforced concrete, plastic or metal. In case of disks, that are made separately from trunk, they are fixed to each other by inserted bolt joints or made with close conjugation with pyramidal piles and with slipping disks over piles or by making disks and prismatic piles monolithic. Lower broadenings, conjugated in upper part of nozzle, are made conical. EFFECT: pile of landslide-prevention structures, used on soft grounds, is used in construction. 2 cl, 20 dwg
