FORMATION METHOD OF SMALL-SIZED FLOTATION RAFTS SECTIONS AT MINIROAD Russian patent published in 2017 - IPC B63B35/62 

FIELD: transportation.

SUBSTANCE: formation method of small-sized flotation rafts sections is that make the turn at the first beam of the edge guide by boardsill, fixed after the tightening by two arc clips, then the first turned beam is unfolded around the auxiliary beam angle and release it downstream upto the tension of the boardstill and then dip the next beam in the water, unfold it and correcting by the hook, accompany it upto the contact with the first beam. Continue the collection of the edge guide with the periodic etching of boardsill, then form the inner section guide, further one more auxiliary beam is suspended to the forming device, which is positioned at the river side from the anchor nearest to the shore. The end of the auxiliary rope after two or three turns around the anchor stack at the nearest auxiliary beam. Then, the first beam is supplied for the inner guide, two turns near the bracings are made on it by the auxilliary rope, so that the auxiliary rope is remained above, placed along the beam axis, and then etch the auxiliary rope. The newly supplied beams are fastened to the auxiliary rope by using the temporary wire clamps, similar continuing the actions upto the desired guide length collection, corresponding to the section length.

EFFECT: reduction of the labour costs and the number of required floating structures for the formation of the raft.
