Corinth Canal repair work

Interesting videos of Corinth Canal repair work.

No edge protection, excavator standing on ground that was undercut, back tipping of an unprotected edge. All third world practices.

Thanks for that. It so happens that today we enquired about Sailing Holidays annual delivery flotilla that we partook of a decade ago. Then the canal was still open so we went that way. But I gather the canal is expected to be open only at high season in 2023, so no use for the delivery trips which will have to go the long way round.

Good grief! That's scary!!

Very different from the original technique involving dangling on ropes using footholds which you could still see cut into the canal walls (and I think are visible in the video!)...

Is that hard soil or soft stone?

Not familiar with the concept of boulder clay then.

Not familiar with the concept of boulder clay then.

As the exposure is clearly stratified and well ordered even in the highest levels there is no evidence for there being any boulder clay which in any case would only amount to a meter or so. Without looking up the geology it would seem to be sedimentary rock, clay and shales.

Strange way to repair a rock fall blocking the canal. Tip more stuff into it?

I couldn't figure that out either. Then go to lengths to put diggers and cranes on the spoil in the canal? Mist be cheaper to lift into a boat and ship out?

I am sure they know what they are doing

I am sure they know what they are doing

Tbh, their digger and HGV work gave me the fear, so am not completely convinced that they do know what they are doing! Easy for me to criticise...

I would guess not knowing any details of the slip and nature of the remaining wall around it they have created a working platform to pull down the slipped material once the adjacent face is stable and the slipped material has been identified it will probable be loaded onto barges and removed until only a small platform is left which will then be removed by a floating excavator again into a barge. All supposition because from what you can see and without actually being there it's impossible to devise a working scheme, it may be necessary to cut back the face to expose stable material, which ever it's a big job with some very sloppy and unsafe working practices which no doubt they will get away with until it all goes horribly wrong for someone. As a quarry manager responsible directly for 4 large working quarries and indirectly for 14 others performing geo technical appraisals and working with specialist geologists to oversee geotechnical assessments and producing working schemes for extraction and restoration what I see horrifies me and would have resulted in sanction by a HSE quarry inspector if he had seen it in the UK.

If they are going to have to cut away a lot of material to get to a stable surface, perhaps they would be better off bringing in a quarry company! ;-)

I am sure they have but then different rules and practices exist in different countries where regulation and enforcement differs.

True, but I had in mind financial benefit. As in "to the winner the spoil", or literally "better off"... (Maybe the original canal was cut as a quarrying activity?)
