Trenching and Excavation Safety

A trench is defined as a narrow excavation (in relation to its length) made below the surface of the ground. In general, the depth of a trench is greater than its width, but the width of a trench (measured at the bottom) is not greater than 15 feet (4.6 m). What are the dangers of trenching and excavation operations?

Excavation Shoring: Conventional soldier piles with tieback anchors/internal bracing, soil nailing, or composite soil nailing shoring systems appear feasible from a geotechnical standpoint to support excavation required to construct the below grade portions of the building.

Excavation and Trenching - Hazards and how to control them

The requirements are as follows: - For each foot of trench depth, the ratio of slope measured from the trench edge at ground height must be: Soil Type A – ¾ to 1 (53°) Soil Type B – 1 to 1 (45°) Soil Type C – 1 ½ to 1 (34°) Shoring Shoring is one of the most common used methods of worker protection.

Hydraulic shoring: This is a prefabricated strut and/or wale system manufactured of aluminum or steel. Hydraulic shoring provides a critical safety advantage over timber shoring because workers do not have to enter the trench to install or remove hydraulic shoring (see Figure 2). Hydraulic shoring should be checked at least once per shift for ...
