Trench stretch is caused by a number of factors, including:
* The weight of the soil and any structures within it
* The depth and width of the excavation
* The type of soil
* The moisture content of the soil
Trench stretch can be minimized by taking a number of precautions, such as:
* Using a trench box or shoring system to support the sides of the excavation
* Compacting the soil around the excavation
* Installing a drainage system to remove water from the excavation
* Monitoring the excavation for signs of trench stretch
Trench stretch is a serious safety hazard that can cause significant damage. By taking the proper precautions, you can minimize the risk of trench stretch and keep your workers safe.
