  • Trenching and Excavation Safety

    Actual slope means the slope to which an excavation face is excavated. Distress means that the soil is in a condition where a cave-in is imminent or is likely to occur. Distress is evidenced by such phenomena as the development of fissures in the face of or adjacent to an open excavation; the subsidence of the edge of an excavation; the slumping of material from the face or the bulging or heaving of material from the …

  • 9 Tips for Safer Slope Work - Construction Business Owner

    Apr 05, 2019 · And working on a slope requires more attention than working on flat ground. Excavators are capable of climbing some very steep inclines, and drivers should proceed with caution when doing so. 2. Use experienced operators. This work is not something the new guy should tackle. It takes coordination and experience to maneuver a slope.

  • What is 1:1 Slope Excavation? How does it differ from

    Answer (1 of 4): The 1:1 simply refers to the ratio of the rise and run of the slope, so 1:1 means you'll have a 45 degree slope for your excavation. Shored excavations are typically done vertically, in order to reduce the overall area of impact. In some cases sloped excavation and shoring are

    Statement (I): The excavation of side slope of a irrigation canal for claying type of soil should be made at 1 : 1 (i.e. 1 horizontal to 1 vertical) which is taken as nearly equal to the angle of internal friction of the soil. Statement (II): The angle of internal friction represents the stable slope when the excavated soil, or soil in loose conditions, assumes when dumped in situ.
