Right here in Greece we shouldn’t have the tradition of undertaking upkeep – There’s no keep an eye on of tasks after their development – They’re most often left to their very own gadgets
The Professor of Dynamic Tectonics and Implemented Geology, president of OASP, Euthymios Lekkasexpressed his personal opinion at the factor of Kifissos and the doable static instability of the Nationwide Highway undertaking because of the formation of lakes within the mattress of the underground river, within the Newsroom program of ERT.
As for together with her 3rd underground lake found out in Kifissos Mr. Lekkas said, amongst different issues:
“I don’t believe so there is a matter of static adequacy in Kifissos and at the nationwide highway basically, which is above Kifissos, however in the end a test is wanted which must be finished by means of specialist civil engineers, who they are going to verify whether or not there’s harm to the partitions of its mattress, boxed mattress”.
Particularly he mentioned that “ponds are not unusual in culverts or dammed rivers because the erosive power of the flowing water first erodes the ground. After all, at the partitions of the encased river we have no idea in what situation it’s. From what it kind of feels, they do not have a large downside, this is, they do not have corrosion. There’s no corrosion within the armature. Subsequently I don’t believe there is a matter of static adequacy in Kifissos and particularly at the Nationwide Highway, which is above Kifissos, however in the end a test is wanted which must be finished by means of specialist civil engineers, who will check whether or not there’s put on at the partitions of the boxed mattress to peer imaginable interventions that are supposed to be finishedif after all there’s one of these factor”.
He added that “it’s the power of the formwork base is other and the power of the partitions is other. The partitions lift so much. The bottom isn’t load-bearing and will best be eroded by means of water. The partitions are load bearing and it looks as if we don’t have any harm there. After all this isn’t us free up from keep an eye on, which must be finished at common periods. After all, they must be pumped out (the water) in order that the corrosion is successfully restored. After all it must be finished there once more repositioning all armaments that had been destroyed but in addition concreting in order that the water flows down a lot more simply.”
Want for upkeep of all tasks
At every other level he discussed “the possibility that exists is prime, since there’s a large number of motion, it’s the central axis of the basin. Past that, then again, what you rightly identified once more, is the problem of tradition. Right here in Greece we shouldn’t have the tradition of undertaking upkeep. There’s no keep an eye on of the tasks after their development. They’re most often left to their very own gadgets. After all, there’s a very large effort by means of the Technical Chamber of Greece to sign up the bridges, to have keep an eye on and tracking techniques of the deformations and the opposite knowledge that we will have to have at a central stage for the entire nation’s bridges.
Subsequently, there’s a procedure in development so that each one technical works are monitored, particularly the bridges, which might be of explicit significance now not just for Kifissos however for all of Greece. I feel that we’re not off course, however we wish to support the extent of upkeep of all tasks all the way through Greece».
As for whether or not there’s a case if we see pictures of Valencia, Mr. Lekkas mentioned “consistent with the observations we had from the primary second of the transition to Valencia, is that we wish to revise our making plans globally, for the reason that local weather disaster is ongoing. Issues aren’t as they had been sooner than 10 or 30 and 40 and 50 years have modified. Subsequently, our making plans should trade” and he added: “However that is not all. We shouldn’t have an good enough stage of working out of herbal processes or herbal phenomena. It developed and can evolve with explicit depth and the next time period, used to be evolving hundreds of thousands of years in the past. We designed in response to the information we believed to be right kind. Sadly, the instance of Valencia is an instance that overturns our undertaking making plans philosophy, which tells us that right here we’re coping with new knowledge.”
