ALL SEASON ROAD PLOTOVOLEDYANAYA ferried increased carrying capacity

摘要

The invention relates to the field of devices of all-season road crossings over the non-navigable rivers with drifting ice on regular ice roads and permanent roads. In addition, these crossings can be arranged to bypass the fixed bridges, construction or reconstruction of which made for a few years, as well as on the roads in emergencies. The object of the utility model is to provide an all-weather road crossing plotovoledyanoy increased load capacity. The technical problem is solved by the fact that said passage consists of ice and frozen in the ice timber rafts, united in a single structure attached to the raft with two steel cables ends by split nodes are connected with four anchored tensioning winches, two on each bank is different in that the lower planes of rafts by security bars attached between inflatable vessels made of solid matter and intended to increase the load capacity crossing, in which summer can be used as convoys of rafts tape bridge. Before Spring break convoys of rafts part crossing does not understand, but in the beginning of the ice flow rotates around specific axis of the pile and placed in the prepared lane along the shore below ldootboynoy wall for a period of ice-break, after which the newly rotation is output to the crossing axis secured thereon ropes and used as convoys of rafts-ribbon bridge in the summer.
