friends, now it is really funny! But, as every good fun, and this is a serious core. As we read in the newspaper Saxon (24-25 10th 09, p. 18.) "Dam building in Coswig could also be done later" - but then only at night, because then full while driving. Ei! The look I want! Tear down the dam and building of the dam - and with full driving at night! Oh great!
is what we have heard it once before, back in 14 days in the stock market. And with an undertone in which resonated the thought: If it does not agree with the now, what we do, we rob you of sleep for years.
But stay friends, we are told that not upgrading the dam's possible without the complete demolition and reconstruction of the dam? Since we are in the project that we exists and has been approved before.'s all we do not, yes!
But why does the German Railway AG more? - Tear down a dam, mix the sand with cement and won again, flashing her Will test as a still unproven technology?
What is the risk the procedure, a space which shows us in the same newspaper Gunnar juice very clearly (SZ 24./25.10.09, p.10). "Concrete cancer" said the practitioner. "Alkali-silica reaction" (abbreviated AKR) says the academics. There on the highways you have to "just" replace crumbling road surfaces. What is high when the cancer that attacks in dense vehicular traffic involved dam? Without careful preliminary investigations by specialists, this "cancer risk" very large. For over 20 years, is known. For over 20 years, we know how to avoid it.
I'm all for experimentation. I am also for large scale experiments. I'm strain but not for large-scale tests, the outsiders, or even cause harm. When the web-AG wants to test this procedure, but then have to be found 750 m embankment just outside densely populated.
Alles das sei nur eine Unterstellung? Na, dann bauen Sie doch nach dem Projekt, das uns als Planfeststellungsbeschluss von 2004 vorliegt und das schon einmal genehmigt worden ist. Mehr wollen wir wirklich nicht.
