| Zusammenfassung: | FIELD: mining and construction. SUBSTANCE: bucket has body and curved cutting edge in shape of ellipse. Large axis of ellipse is found in section of pit of ground base and directed vertically to provide for excavation of beds (pits) elliptic in shape for laying of pipes on ground natural base. EFFECT: reduced power consumption in ground cutting, higher labor productivity in pipe laying and increased quality and prolonged service life of pipelines. 2 dwgl |
