RU2695578C1 - Method to increase bearing capacity of ice cover - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: invention relates to ice-breakers and can be used in making ice crossings. Method consists in the fact that the bearing capacity of the ice cover is increased by means of pipes lowered under the ice cover through the through holes made in the ice cover on both edges of the crossing along its entire length. Pipes are communicated with atmospheric air. Pipes are made corrugated from heat-conducting resilient material. Corrugating pipes are springs. Pipes connected to each other, in compressed state, are placed into a container, when it is placed under ice and its subsequent opening with compressed springs pipes are able under ice to form a grid of pipes, which are interconnected by air.

EFFECT: higher reliability of ice crossing operation is ensured by ensuring independence of its carrying capacity against water level fluctuations in water reservoir.

Description

The invention relates to the field of ice engineering and can be used to create an ice ferry for transporting goods.

A technical solution is known (RF patent No. 2135685), in which the method of creating an ice crossing consists in placing steel pipes under the ice, dropped vertically to the bottom of the pool through the through holes formed in the ice cover along both edges of the crossing along its entire length, with the bottom end of the pipes made brewed, and its upper end protrudes above the ice surface. Cold air, as heavier, enters the pipes, causing ice to freeze over their entire outer surface. After a sufficient time has elapsed for reliable freezing of the lower and upper parts of the pipes to the bottom of the pool and the ice cover, respectively, and the ice layer of the required thickness freezes on the pipe surfaces, the ice crossing is ready for operation.

The disadvantage of this method is the inability to use it at great depths of the reservoir.

The objective of the claimed invention is the creation of an ice crossing, the bearing capacity of which would not depend on the depth of the reservoir.

The technical result achieved by solving the problem is to increase the degree of reliability of the operation of the ice crossing.

The essential features characterizing the invention.

Restrictive: the load-bearing capacity of the ice sheet is increased by means of steel pipes lowered under the ice sheet through the through holes formed in the ice sheet on both edges of the crossing along its entire length, the pipes communicate with atmospheric air.

Distinctive: the pipes are corrugated from a heat-conducting easily deformable elastic material, the corrugating pipes are springs, the pipes connected to each other are placed in a compressed state in a container, which is placed under ice and open it with the formation of a lattice of pipes communicating with each other by air.

The method is as follows.

Rows of through holes are drilled in the ice sheet on both sides of the intended cargo transportation path. Through them, containers are immersed under the ice, inside of which the corrugated pipes connected to each other are laid in a compressed state. The pipes are made of a heat-conducting elastic material, for example, of a metal foil, while the corrugating elements are springs made, for example, of metal. After the containers are submerged under ice, they are opened. Compressed springs with compressed pipes straighten due to their corrugations. As a result, under the ice there will appear peculiar closed lattices of pipes, interconnected by air. Thanks to the common duct, they are also provided with communication with atmospheric air. Then, the ice crossing thus prepared is subjected to negative temperatures. Cold heavy air (t <0 ° C) entering the pipes will cause ice to freeze over their entire outer surface, i.e. the formation of peculiar pontoons under the ice cover, increasing its bearing capacity due to the buoyancy and stiffness created by them (the average thickness of the ice cover at the lattice location will increase). As a result, the claimed technical result will be achieved.

The invention is illustrated graphically, where: in FIG. 1 shows a general view of a crossing; in FIG. 2 - view of it from above; in FIG. 3 is a section BB in FIG. 2; in FIG. 4 is a section BB in FIG. 2.

In the ice sheet 1, on both sides of the intended cargo transportation path 2, rows of holes 3 are prepared through which containers 4 are immersed under the ice (Fig. 1). After their opening under the ice there will be a lattice 5 (Fig. 2) from corrugated pipes 6 (Fig. 2, 3) with common air ducts 7 (Fig. 3, 4). Cold air 8 entering the pipes 6 will cause ice 9 to freeze on them and freeze water in the holes 2 (Fig. 4).
