On Tuesday, following the installation of the metal grilles,
the brickwork was carefully cleaned.
Farwell is still closed from the L viaduct to Wayne. Huge holes have been dug
and covered with heavy steel panels, while other heavy metal objects
have been moved around. I'm curious to learn what the thing in the
bottom picture is for--it's an imposing looking thing!
*** UPDATE 16 May: Thanks to the commentor who explained that the object
pictured below is a trench box, a safety feature designed to keep the walls
of a deep excavation from collapsing. On the post for 6 May there is
a picture of a trench box in use.
That's a trench box. It is used in deep excavations that are also narrow to protect the excavation from caving in but also allows someone to work within that excavation safely. They are also mandated by OSHA depending on the depth of the excavation.
ReplyDeleteThanks for the info!
DeleteThe photo you posted in your May 6th post shows a trench box already in the ground.
