Method of making ice ferry

FIELD: transport, construction.

SUBSTANCE: method of producing ice ferry consists in cleaning ice surface of snow, placing a layer of heat-isolation material through the cut, along the ice ferry routed, and pressing aforesaid layer to the ice layer lower surface. A continuous layer of ice floats is placed between the ice surface lower surface and the said heat-isolation material.

EFFECT: higher load-carrying capacity of ice ferry.

 

The scope to which the invention relates.

The invention relates to the field of latenite and can be used when creating the ice terminal for the transportation of cargo.

The level of technology

Known technical solution (1. Peschansky, I.S., Lagoudera and hladotehnika. - L.: Sea transport. 1963, - 245 C.)in which to intensify ice for ice crossing is proposed in advance to clear the ice from snow. The lack of technical solutions is insufficient bearing capacity of the ice cover that is used as a terminal, due to the low strength of the lower layers of ice due to the temperature drop across the thickness of the ice cover from 0C on the bottom edge up to the ambient temperature at the upper edge of the ice, as the temperature increases, the ice strength is reduced (2. Bogorodsky CENTURIES, Gavrilo VP Ice. The physical properties. Modern methods of glaciology. -L.: Gidrometeoizdat, 1981, - 384 S.).

The closest is a technical solution (3. EN 2149945 Cl, 27.05.2000)in which to increase the strength of the ice cover reduces the temperature of the lower part of the ice by placing a layer of insulating material under the ice and tighten it to the lower surface of the ice cover. The disadvantage of this technical solution is the low temperature reduction rate of the n is sung of the ice surface due to positive temperature insulation layer, with the temperature of the upper water layers, i.e. cooling occurs only on one side of the upper strata of the ice cover, as well as a low speed increasing the thickness of the ice cover due to natural freezing of water flowing through the permeable insulating material.

Disclosure of inventions

The task of the invention is to provide a reliable ice crossing.

Technical result achieved when the task is to increase the strength of the ice cover.

The essential features characterizing the invention.

Restrictive: ice crossing is generated by Stripping the surface of the ice snow, the premises of the insulation layer under the ice and compression to the lower surface of the ice cover.

Distinguishing between the bottom surface of the ice cover and the insulating material is placed a layer of ice.

It is known [2]that the temperature decrease of the ice cover leads to an increase in its strength characteristics and a more intensive growth of its thickness. When placed under the bottom surface of the ice cover additional layer of ice, the speed of lowering the temperature of the bottom layer of the ice cover increases, and the magnitude of the temperature drop across the thickness, which leads to accelerated is dostijeniu greater strength of the ice. Water that is trapped between the lower surface of the ice cover and the upper surface placed beneath the ice cover layer of ice that freezes much faster due to cooling with ice top and bottom, forming into a single monolith of ice and placed under a layer of ice. Thus, the bearing capacity of the ice crossing increases as due to the rapid increase of the strength properties of ice, and due to the rapid increase of the thickness of the ice cover.

The implementation of the invention

The method is as follows. The surface of the ice clear of snow. Along the ice crossing prepare pieces of ice of rectangular shape, one side of which is greater than the width of the terminal. Prepared ice through the slots near the ice crossing is slid under the ice so that the ice was located by a continuous layer under the entire crossing. Through these slits under the ice injected insulating material and press it to the ice. After the time required for the complete freezing of the water layer between the ice cover and a layer of ice, the ferry is ready for operation.

The way to create icy crossing, which consists in cleaning the surface of the ice from the snow, placing a layer of insulating material through a slot along the intended path of the ice terminal, characterized in that prepare Idina and slid through the slot under the ice with the formation of a continuous layer, then through the same slits injected insulating material and press it to the ice.
