BULK EXCAVATION, FILLING, ETC. Open face excavation in earth, not exceeding 2m deep: Excavate over site to reduced level. [m3] A 100m road is to be built on hill slope by cut and fill excavation. By referring to the drawings (Fig A), takeoff the quantities for excavation and filling. Calculations: Two lane road – 3.25m x 2 = 6.5m wide.

The Excavation standards describe various methods and approaches that can be used to design protective systems. Examples of protective systems that can be used to comply with the Excavation standards include: Sloping the sides of the excavation to an angle not steeper than 1½:1 (for every foot of depth, the trench must be

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.

Jul 16, 2020 · In this example, we have a trench of unknown length with the sides of the excavation cut back at a slope of 1:1. The bottom of the trench is 5 feet wide. If we assume the depth is also 5 feet, then the top of the trench is 15 feet wide. The cross-sectional area of the trench is (5+15)/2*5, or the average trench width of 10 feet * 5 feet deep

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 …
