RMweb Premium Simon Lee Posted March 30, 2016 RMweb Premium Share Posted March 30, 2016 The piles and concrete raft sort out the trackbed, is there any news on the seawall foundations which once exposed caused the original trouble.As to the timescales. I would suggest one pile per working day so that's 20 weeks plus the time to cast the raft and any crossbeams so 9 months sounds about right.Jamie Nothing on the Dover Marinas site about the seawall, though it has been mentioned on other forums regarding the changes in Longshore drift of shingle since Samphire Hoe was built. Don't know if the new construction could be left "open plan" for the sea to wash under like a viaduct / bridge and the old sea wall left as a sacrificial barrier ? 2 Link to comment Share on other sites More sharing options...
RMweb Premium Gwiwer Posted March 30, 2016 RMweb Premium Share Posted March 30, 2016 Extract, from Nigels F/B a lasting erection First piles now this!!! I do enjoy engineering jargon though. "Arisings" being the dirt brought up from the hole and "mucked away" is nothing more than the dirt being removed. As a geology graduate we encountered other such words. What many people call "lava" from a volcano is actually comprised of much more than just the lave - usually ash, steam, smoke and noxious gases - the sum total of which is called "ejectamenta" Flip to down-under mode for a moment and bear with me. My suburban rail line is having three level crossings removed currently as part of a program to eliminate fifty network-wide. Because the sites are mid-suburban locations with not one additional centimetre of footprint available the technique is to construct a wall of deep piles using exactly the method to be employed at Shakespeare Cliff. Here they are dug, filled with the cage and concrete and the next then dug quite literally touching the first to form a solid wall. Road bridge structures are also pre-installed using similar techniques and the future deck has train track temporarily laid across the top. Once this is all built the railway can then be closed and the track bed dug out (during a nine week shut-down in June and July) to the lower level with the major structures in place and only requiring finishing. There's not a lot of noise. There is low-level vibration during piling but the machines - every bit as big as those at Dover - are very quiet in operation. 2 Link to comment Share on other sites More sharing options...
jukebox Posted March 31, 2016 Share Posted March 31, 2016 "Approximately 25 cubic metres of arisings from each pile will be mucked away from site using engineering trains." I think that may explain this work: It could be a bay for site tipping trucks to haul the spoil and stockpile a train's worth, ready to be loaded out. The concrete barriers would keep the muck in one spot on site. 2 Link to comment Share on other sites More sharing options...
David Todd Posted March 31, 2016 Share Posted March 31, 2016 Timescales ? Would that be ? Round the clock working, 3x 8 hour shifts. 2 X 8 hour shifts or 1, 8 hour day shift. If,the upper part of the new footbridge is to be made of, glass reenforced plastics, it will be soon encrusted with seawater,salt deposits, And render it useless, as a photographic platform, self cleaning outer skin could be an option.

RMweb Gold The Stationmaster Posted March 31, 2016 RMweb Gold Share Posted March 31, 2016 "Approximately 25 cubic metres of arisings from each pile will be mucked away from site using engineering trains." I think that may explain this work: Sump.jpg It could be a bay for site tipping trucks to haul the spoil and stockpile a train's worth, ready to be loaded out. The concrete barriers would keep the muck in one spot on site. But not very well sited for loading a train (in fact next to useless as it would only give access to a handful of wagons). To enable a sensible loading situation - with, ideally, a couple of machines working - that area is far too short and relatively narrow and it's also lower than the surrounding ground and the railway. Best loading is from wagon rave height as the operator can not only see where he is loading into the wagon but damage to wagons is minimised simply because the operator(s) can see them. The other pertinent thing is the quantities - if each bore produces around 25 cubic metres of muck that would be what - not far off 30 tonnes so possibly no more than part of wagonload (depending on which wagons are used). It's hardly economical to run a train for a handful of wagons if there's room to stand the muck on site somewhere so we're unlikely to see a train until there's something in the region of 20 wagonloads to move out. The only reason for doing it more expensively and moving out smaller quantities is if there is nowhere to stand the stuff prior to loading. I suspect with a reasonable amount of room to dump muck near the site we are more likely to see that happen - say the previous unloading area - rather than see money thrown away on lots of small trains (which basically cost about the same to run as a much larger train). Unless of course the actual rate of extracting the muck is far quicker than has been suggested thus far in this thread which would make more frequent trains viable with decent loads. 1 Link to comment Share on other sites More sharing options...
jukebox Posted March 31, 2016 Share Posted March 31, 2016 But not very well sited for loading a train (in fact next to useless as it would only give access to a handful of wagons). *snip* Possibly, but if I were the local perway engineer, I'd be wanting to minimise the area of ballast that might be contaminated by spoil during loading - by covering the loadout zone in geotextile for a couple of wagon lengths - and draw the train through that loading point, filling one or two wagons at a go, not unlike a merry go round (as you call them there) train going under a hopper. I can't be sure from the photos, but thought the compound looked about a train length away from the end of the track - top and tail an empty train to site all the way to the buffers, draw back gradually to load, then leave site. I guess we'll see in due course! Link to comment Share on other sites More sharing options...

I am trying to respond to both of your suggestions,but unable to upload a photo from my laptop. So have to use this iPad. Look at the photos, Look at the length of the bay, Then look at the wagons, estimate how many can be brought,alongside the bay. Consider the buffer stops on the down line on the 10 chain curve. A shuttle service,could be used,from the site,into Dover Priory, utilising the scissors crossing, between passenger train movements. 2 locos, working 6 wagons each. Shunt loaded wagons into the down line siding, once fully laden, double head,the loaded wagons,away. Maybe, they have,other machines,in mind,for the working loading height difference?

But if NR/the freight operator are forced into doing something like that, or more likely just running a shorter train, they will just have to bite their lips and Nr will have to carry the extra costs. If you were going to load of a pile of muck the logical place would be to put it as near as possible to the Dover station end and load from a pile of material in order to get the height. I know what I have seen was with much higher wagons but it is worrying just how much damage can be done to wagons by bucket loading if it is rushed or not done with a clear sight down onto the wagon raves.

sfbct15 Posted March 31, 2016 Share Posted March 31, 2016 Reading on another Forum that Network Rail are considering the permanent closure of the line between Folkestone and Dover? Not entirely surprised, the cost of maintaining the line may just become too much? My sense throughout this has been that the protection of the A20 is more important than the railway and the cliff need to be stabilised to secure this route? If the A20 were to fall into the sea the Port of Dover would grind to a halt....So the current work protects the A20 but that may not mean the rail line re-opens? Is the line as vulnerable further to the west? Are journey time to Dover compatible via Canterbury/Ashford? Link to comment Share on other sites More sharing options...
runs as required Posted March 31, 2016 Share Posted March 31, 2016 You don't think the 'Beachwalk - full survey' pair could be a cunning ploy to keep you, the mystery photographer, from getting 'a tad bored'? dh 2 Link to comment Share on other sites More sharing options...
