Rome - Shoring System Failure

[GeoPaveTraffic]

Shoring system failure in Rome, even though this is called a "sinkhole".

Looks like some sort of secant wall system based on the photos. Should be interesting to see how this gets worked out.

Can't really tell what is supporting the vertical cut above the secant pile wall along the side that did not collapse.

Looks like a gunite/soil-nail system in place above the wall.

That is not a "sink-hole", it's a catastrophic failure caused by lateral support loss which was clearly evident months in advance. Utter fail, heads must roll.

Thanks for sharing,

I agree Mike.

Also, reading the story sounds like the failure was ongoing for several days, maybe weeks. People reported cracks in the pavement,etc. but apparently nothing was done. Got to be more to this story.

Shoring only half of the way up that cut surprised me that this shoring system did not fail earlier. .

Appears that only half of the height of the excavation was supported. The bottom of the excavation is wet, so, perhaps they had some rainy days before the failure.
