Question:- Which method of protection involves vertical sidewalls with horizontal struts?


The means of protection which mean the vertical sidewalls with horizontal struts is trench shoring. Trench shoring is a method of canceling the soil cave-in and securing the workers when working on excavation deep in the narrow trenches. The retention is done by constructing vertical shoring walls alongside the trench with horizontal hydraulic or metal struts that are securely anchored to the walls.

The formworks walls, which can be made of steel or aluminum, support the excavation while the horizontal struts keep them from moving. The struts make it possible to build a wall that encloses the trench like a box frame. And since these supports are in place overhead and at the sidewalls, the workers are able to work in a safe workspace inside the trench and to prevent any dangerous collapses. Appropriate trench shoring includes the structural stability evaluation of the soil, depth of the trench, and also forces acting on the walls. The components should have the right size and be correctly matched to the lateral forces which are calculated. Installation of trench shoring materials make it possible for trenches to be dug even in the poor soil conditions. In addition to this, the workers must be trained on the right shoring procedures as well. As long as it is installed correctly, trench shoring’s vertical walls and horizontal rails are able to prevent the catastrophic collapse.
