FIELD: bridge building, particularly to erect bridge piers in rivers to be covered with ice and subjected to ice drift.
SUBSTANCE: rigging comprises support system including cross-beam and leading piles to which rigid frame with guiding means for posts is connected by upper beam system. Rigid frame is made as parallelepiped with bottom having orifices for post passage with removable water-tight heat-protective side walls connected with bottom and one with another through packing means. Upper beams connected with removable water-tight heat-shielding side walls by sectional connection means are provided with rests to connect thereof with support system cross-beam. Guiding means for posts are secured in bottom from bottoms thereof.
EFFECT: reduced material consumption and labor inputs during high pile grillage constriction.
