METHOD FOR CLOSING CRACKS IN ICE MASSIF

摘要

FIELD: construction.SUBSTANCE: in ice massif, at certain distance L from crack edge an inclined cut is made at angle more than 45 degrees towards crack and at edges of this inclined cut vertical cuts are made perpendicular to crack propagation direction so that ice slab cut in this way slips under gravity along inclined surface and closes the crack. After crack closure depression formed at surface of ice structure is filled with snow and compacted until it acquired required strength.EFFECT: crack closure method allows reliable blocking of the crack upper part, smoothening of formed depression by snow filling and compaction and ensuring strength characteristics for damaged surface area of the ice structure.3 dwg
