Trench Shields and Steel Plate Used to Form Bore Pit Coble Trench Safety shoring specialist Brett Sondergard plays a key role in assisting contractor with shoring design. The Specifics A municipality had plans to expand its water infrastructure and was adding a new water tower, which would require water lines being ran to the tower.  The lines would have to be connected to the main lines, which would require boring beneath a highway to make the connection.  The contractor would be boring and would need the bore pit to be 12 feet deep 10 feet wide and 24 feet long.

The contractor elected to use an 8 feet tall steel trench shield with a 4 feet tall steel trench shield stacker to provide the requisite shoring for 12 feet of depth.  The steel trench shields were then capped with steel plates on both ends to provide full soil support.  After traffic had been diverted and it was time for the bore, the steel plate adjacent to the road was removed and the boring tool began the bore that would allow the new water line to be connected to the existing line. The project went very smoothly and produced no incidents with respect to the shoring system.  The contractor was very satisfied with the knowledge and attentiveness of the Coble Trench Safety staff, which allowed for a more thorough focus upon the project as opposed to worrying with the shoring system.
