Abstract

1. An all-weather raft-ice rafting highway of increased carrying capacity, consisting of ice cover and rafts frozen into ice, united in a single structure by two steel cables attached to rafts, the ends of which are connected through four detachable nodes to four anchored tensioning winches: two on each bank, characterized in that inflatable tanks made of durable material are attached to the lower planes of all rafts between the guard bars. 2. The crossing according to claim 1, characterized in that before the spring ice drift the raft portion of the crossing is not disassembled, and at the beginning of the ice drift it turns around a special axis-piles and is placed in a prepared lane along the coast below the ice-breaking wall for the period of ice drift, after which it is again turned onto the crossing axis is fixed on it with ropes and is used as a raft bridge-tape in the summer.

Description

The utility model relates to the field of all-season road crossings through non-navigable rivers with ice drift on regular winter winters and on permanent roads. In addition, such crossings can be arranged on bypasses of permanent bridges, the construction or reconstruction of which is carried out over several years, as well as on roads in emergency situations.

Various designs of summer and winter road crossings are known. Closest to the claimed model is the construction of the ice crossing, in which the ice cover is reinforced by the upper structure from wooden cross-beams and flooring located on the surface of the ice cover [1.2.3].

The main disadvantage of the reinforced ice crossing adopted for the prototype is the need to disassemble the upper reinforcement before the ice drift and its device again next winter after the formation of an ice cover of sufficient thickness [4].

The technical task of the utility model is the creation of an all-weather rafted cross-country road crossing of increased carrying capacity.

The technical problem is solved due to the fact that the indicated crossing consists of ice cover and wooden rafts frozen into ice, united in a single structure with two steel cables attached to rafts, the ends of which are connected to four anchored tensioning winches, two on each bank, through split units the fact that inflatable tanks made of durable material are attached to the lower planes of all rafts between the guard bars, designed to increase the carrying capacity of the crossing, which in tny period may be used as a tape-bridge. Before the spring ice drift, the raft part of the crossing is not dismantled, but at the beginning of the ice drift it turns around a special axis-piles and is placed in a prepared lane along the coast below the ice-breaking wall for the period of ice drift, after which it is again turned onto the crossing axis and fixed with ropes on it.

The construction of the ferry and its elements are shown in FIG. one.

In FIG. 1 shows: the plan of the crossing (a), the facade (b), the placement of the raft crossing along the shore (c), the cross section of the crossing (d), the view of the part of the crossing from below (e), where it is indicated: pos. 1 - raft; pos. 2 - steel cable; pos. 3 - detachable node; pos. 4 - wheel ring; pos. 5 - gauge flooring; pos. 6 - tension winch; pos. 7 - pile anchor winch; pos. 8 - guide pile; pos. 9 - a ramp; pos. 10 - shore lag; pos. 11 - access to the crossing; pos. 12 - axis-pile rotation of the raft; pos. 13 - sub-guard guard bars; pos. 14 - ice cover; pos. 15 - ice breaker wall; pos. 16 - direction of water flow; pos. 17 -inflatable tank.

The ravine-ice crossing is an extended structure consisting of an ice cover 14 and wooden rafts 1 frozen in ice, reinforced by inflatable tanks 17, and connected by two steel cables 2 into a single structure. At the top, rafts 1 are equipped with wheel breakers 4 and track floor 5. A part of the cables 2 within the rafts 1 ends with detachable nodes 3, which allow disconnecting the cables 2 from the tensioning winches 6 with anchors 7 (for example, from screw piles).

The manufacture of the raft portion of the crossing is carried out in the warm period on the water along the coast until the freezing.

The aiming of the raft part 1 "rotation" is as follows.

The lower cable 2 from the upper winch 6, located above the crossing on the left bank, is connected through the node 3 with the raft part 1. The rope is pulled by this winch 6, and the raft part 1 is turned against the current around the axis-piles 12 to the design position. After that, the top cable 2, attached to the raft part 1 through nodes 3 is connected to the coastal parts of the ropes 2 of the remaining winches 6. Winches 6 tension the ropes 2. The raft part is fixed on the crossing axis. The ramps 9 are laid from the raft on coastal beds 10.

With the onset of freezing, the raft part 1 freezes into the ice cover 14. The accumulation of ice occurring from below under the raft part increases the carrying capacity of the crossing.

Before the onset of the ice drift, the raft part 1 is not disassembled, but disconnected from the winch 6 of the left bank and, with the flow, rotates around the axis of the pile 12 and is placed along the right bank in the prepared mine below the ice break wall 15 for the period of the ice drift, after which the raft part 1 is again withdrawn by cables 2 and winches 6 on the crossing axis. The raft part 1 is used in the summer as a floating raft bridge-tape.
