Ensuring the stability of used excavator walls is critical for safety and project success. Here are some strategies you might consider:
Slope the walls: This method involves cutting back the trench wall at an angle inclined away from the excavation. The slope’s angle depends on the soil type.
Shoring: This involves installing supports (usually made of wood or steel) to prevent soil movement. Hydraulic shoring is a popular choice as it’s easier and safer to install than other types.
Shielding: This involves using trench boxes or shields to prevent soil cave-ins. Always remember, workers should not be in the shield when it’s being moved.
