Granitechops Posted June 17, 2014 Share Posted June 17, 2014 (edited) This afternoon at just before low tide ( spring) got down beyond the end of the groynes end of groyne 1, the one that collapsed most in the Feb storms end of groyne 2 ( the No. is on the end just below the basket) end of groyne 3 Further back the other way towards Redrock there has appeared a double row of stantions and a circle of stone/rock at the seaward end was there a jetty there?? Did the Norwegian barges have to tie up to something in the early 1990s? to unload their stone? or does it predate that? going back previously to the siding laid for the 1928 stone sea defences there is evidence in todays path back from Redrock that when lifting the siding, some sleepers were not lifted but were covered in Tarmac & are now rotting out, leaving a very undulating path just past the short bit of fencing and before the footbridge Edited June 17, 2014 by Granitechops 1 Link to post Share on other sites More sharing options...
Granitechops Posted June 17, 2014 Share Posted June 17, 2014 That's a "twist rail" Don. The S&C (switch & crossing) is of vertical plane, that is the rail is vertical through the point work there. To make the transition from vertical back to the 'inclined' in the plane line, we use a twist rail. This is fabricated in the factory. That twist rail and possibly together with some other metal work is being renewed. The letter "W" on the timbers mean 'weld'.The "5 mm" marking means there is 5 mm wear on the existing rail to right to which the new twist rail will be welded. Its very important obviously to ensure that the twist is the correct way around! Ive known them more than once be fitted the wrong way around as the twist is extremely difficult to see if its not marked on the new rail. When you factor in about the 15 grand it costs just to fit one rail like that one on a Saturday night, you only wana be doing it once! The wear measurement is to help the welders select the correct mould for the Thermite weld on the night. Ok. thanks, Gary, got the principle involved but how did the rusty, unpolished bit get worn down, so that the wheels are now not touching it & polishing it??

D826 Posted June 17, 2014 Share Posted June 17, 2014 (edited) Found some interesting stuff here, re geology of the area round Dawlish and the sea wall: http://www.southampton.ac.uk/~imw/jpg-Dawlish-Warren/8DLW-Granite-Larvikite.jpg Also showing that there was a siding on the path removed 1941. Confirms that the warren is formed by long shore drift, and the groynes and breakwaters stop sand from going from the bay to the warren. Certainly, when I was a lad, the beach was much higher, though it varied over time. I had a hazy recollection that the groynes between Dawlish town station and the Langstone rock,many of which were timber supported on bullhead rail uprights in the 70s, we're not replaced in the late 70s/80s owing to concern about the sand spit at the warren eroding. May be of interest? Also noticed Rivercider's avatar, (an image which makes me misty eyed with nostalgia since watching the trains there is pretty much what I did maybe 2 years later Rivercider), clearly shoes the footpath that provided a link between the sea wall siding and the footpath at the Langstone Rock when the siding was in place.

Did the Norwegian barges have to tie up to something in the early 1990s? to unload their stone? or does it predate that? 100_2775 (Medium).JPG 100_2781 (Medium).JPG just found a quote from Matt's link by Ian West, Romsey, Hampshire and Visiting Scientist at the:Faculty of Natural and Environmental Sciences,Southampton University, See http://www.southampton.ac.uk/~imw/Dawlish-Warren.htm QUOTE ""The groyne has not become much separated, as yet from the rock so erosion cannot be very fast (although there has been repair work to the landward end of this groyne). East of Red Rock Cafe brickwork has been used to try to reduce erosion. A columnar structure in the sea near the cafe is the relic of a different approach to sea defence, but this method has not been continued. The remaining circular base of the structure is referred to informally at the cafe as the "Dinosaur's Nest". "" Is that reference refering to whats in my photo? EDIT;- NOTE that the "groyne" he refers to is the stone breakwater at Redrock/Langstone rock, now storm damaged I am trying to understand what effect a single "Columnar structure" would have on preventing erosion or drift??

lightengine Posted June 18, 2014 Share Posted June 18, 2014 I am trying to understand what effect a single "Columnar structure" would have on preventing erosion or drift?? Any feature put on a beach, like a groyne, will have an effect on the movement of sand. I have a book showing the breakwater at West Bay in Dorset. It shows that the build up of sand to the eastward of the breakwater was huge and deprived the town beaches of sand on the western side. The gradual loss of those wooden groynes that you photograph are just allowing the gradual movement of marine sediment. Link to post Share on other sites More sharing options...
dcriout Posted June 18, 2014 Share Posted June 18, 2014 Noticed last night on the beach webcam about 7pm the orange army packing up for the night they dragged a machine on to the high level seawall path and left it there. It has disappeared today presumably they are working at low level today as well. Anyone know what it could be? Link to post Share on other sites More sharing options...

Without seeing it myself, its difficult to say. I was there today aswel!! Its probably the way in which its been ground in the past, possibly by the switch grinding team, they'll often grind back away from the switches as far as that. This can result in a differing wheel contact area to the rest of the rail. Edited June 18, 2014 by Gary H Link to post Share on other sites More sharing options...

Without having seen it, I can't really be specific, but the Sea Wall project team are now gearing up to start work on the raising of the walkway, starting in the next few weeks, so it may be connected with ground surveying/testing, perhaps? 1 Link to post Share on other sites More sharing options...
lightengine Posted June 18, 2014 Share Posted June 18, 2014 Meanwhile, over on the Teignmouth seawall, the security guy I spoke to the other day said he had lots of conflicting information as to when it would reopen to pedestrians - September, November, even next year. Not surprising really. Today from the beach I saw 1 guy actually working on the edging stone replacement on the sea wall where the railway starts at the Teignmouth end. There were a couple more guys but they looked more like a phone chatting chappy and a clipboard wielding type, obviously more supervisory than working types. At this staffing/working level, the security men sitting in the sun at the top of the sea wall steps should be very tanned and wealthy come Christmas. If only the Orange army were still around we could get the job finished in a few days rather than months. Has anyone got a conch shell available to summon the Cap'n and his army?

I suspect some of my compadres may even have indulged in the temerity to take a...gasp!.... holiday!!! The walkway from Teignmouth to Smugglers will reopen sooner than some of the more dire predictions.

lightengine Posted June 19, 2014 Share Posted June 19, 2014 No sign of any work at the Teignmouth end of Teignmouth sea wall at 4pm today. 1 security guy today for all the sea wall from thed yacht club to Sprey Point. A few weeks ago there was 1 on each set of steps to the wall. According to this guy the wall is hollow and he cant stand on it, he has to stand on the beach. Obviously the orange army guy that walked along it must either be invincible or he knows where the cavities are! Link to post Share on other sites More sharing options...
Granitechops Posted June 19, 2014 Share Posted June 19, 2014 (edited) Thursday 19th JUNE 2014 having not been in Dawlish since last Sat (14th) I was surprised by the changes First it would appear that work on the down platform offices, windows, roof, gutterring etc appears to have been completed as the safety railing that has been on the edge on the corner has been removed Personallty I am dissapointed, as that bit gets a bit congested when busy, wheelchairs, mums with buggies, people chatting in groups, people sitting on the stone benches, etc I had thought that it looked like a permanant fixture The white line shows the guide for the fixing Anchor bolt holes the railing keeping the public off the steps along from the viaduct towards the old lifeboat house, under the Station platform has been removed and the beach seems to have more sand & less shingle & taking the wheelchair along the beach today the consistancy of the sand has changed since last week felt more soft & sinky strange how such a calm sea as we seem to have had over the last week has changed the beach Edited June 19, 2014 by Granitechops Link to post Share on other sites More sharing options...
Granitechops Posted June 19, 2014 Share Posted June 19, 2014 Shotcrete opertative at work on the breakwater at Boat Cove, obviously the masony has been repaired/replaced first before the coating has been applied working in their small compound the shotcrete compound (powder) is loaded into the hopper the guy lifts the bag onto those nasty looking teeth, the weight splits the bag open, he lift the ends like a cook breaking an egg, the empty bag gets chucked straight into a dumpy bag The powder goes down one pipe water down another & the two mix in the nozzle as it is applied One local observer informed me that the gear & in particular the pallets of shotcrete arrived by barge from Teignmouth docks on a barge with a ramped loading door, being uloaded by the swing shovel felt pity for them, hard hat, face mask, overalls, sweat was running down their faces it must have been 30 degrees in Dawlish today too hot for me, I left soon after 11 am 1 Link to post Share on other sites More sharing options...
