Abstract | FIELD: construction.SUBSTANCE: device comprises the ice crossing in which the holes are made throughout the intended route of cargo transportation on its both sides, through which the reinforced concrete units are lowered under ice by means of cables. Discs are fixed to the upper ends of cables. The length of cables is selected in such a way that the ice doesn't rise above the initial position relative to the bottom when flexural-gravity waves occur. The distance between the openings along the crossing is equal to the length of resonant flexural-gravity waves ?The discs are also installed in the middle between them at a distance from them equal to ?/2, under the ice. On either sides of the crossing all disks are rigidly connected with strong horizontal beams by means of racks.EFFECT: hardening of ice crossing.2 dwg
Изобретение может быть использовано при эксплуатации ледяного покрова в качестве ледяных переправ. Устройство для упрочнения ледяной переправы включает ледяной покров, в котором на всем протяжении намеченного пути транспортировки грузов по обеим его сторонам выполнены отверстия, через которые под лед при помощи тросов опущены железобетонные блоки. К верхним концам тросов прикреплены диски. Длина тросов выбрана с таким расчетом, чтобы при возникновении изгибно-гравитационных волн лед не приподнимался над первоначальным положением относительно дна. Расстояние между отверстиями вдоль переправы равно длине резонансных изгибно-гравитационных волн λПосередине между ними на расстоянии от них, равном λ/2, подо льдом также установлены диски. По одной и другой сторонам переправы все диски при помощи стоек жестко соединены с прочными горизонтальными балками. 2 ил. |
