Folkestone-Dover sea wall wash-out


Recommended Posts

Decided not to go to the site until midday, left at 1400 hours,  as it was a new working week also, a change of crew.

 

I will reiterate, a lunchtime post.

 

The Yellow rig is drilling a seawall pile hole for Raft 2.

 

Adjacent, they are filling a previous drilled hole.

 

Another mixer is in the vicinity, loading concrete to a pump,then transferred via  the pipeline down the seawall,

to the crew who are making the second stage of the concrete pour,on the surface,.

 

Meanwhile, a crew is setting out the first part of Raft 1. near the tunnel mouth's.

 

With the large new crane, transferring materials, across the whole of Raft 1 area.

Hopefully, on site early,with Nigel,DoverMarina.com tomorrow morning,about 0830.

Should imagine there will be a spoil train on site around 0715/30.

 

Yes Mal, beach construction work,should start, the first week of July from the 4 th.

 

It has been said before, the last item in,will be the foot bridge.

I don't know if it's the angle of view but that 'bed' of rebar looks to me to be too close to the seawall and too far from the edge of the cutting and doesn't line up with the tunnels properly.  And yet again I do hope the use of timber won't create routes for water to get in although no doubt it doesn't matter if what's underneath does get gradually washed out as the load will be taken by the piles - but rebar would be exposed once the timber has gone.

 

Seems an odd way of doing it using timber instead of those plastic spacers which are often used as they at least won't rot away.

I've been out of the loop on reinforcing steel for many a year.

The issue of steel in structural concrete being damaged by salt(s) has been so disastrously expensive to rectify over the years that one might expect a steel spec for this severely exposed rebar that attempts to meet the claimed 120 project year life.

 

There have been (expensive) corrosion resistant structural steel sections available for a generation or more that can be specified for marine locations.

Your back in the loop, dh.

How much do you want ?

In this pic - P1430353 - you can see some *very* carefully drawn out markings on the cliff side of the blinding.

 

I suspect they may have a load of "U" shaped rebar, that is turned sideways and tied in to these base lengths, that will extend the steel raft right out to that line. Same on the seaward side.

 

*edit*  Ah, you can even see one such U bar - in that same photo at the bottom left corner of the raft.

 

 

I was wondering how they planned to get all that timber out once the cage is built, and also noticed the lack of "biscuits" used to ensure the steel gets enough cover - and would guess they will build the reo cage in its entirety, then lift it up and put the biscuits underneath to get the 50-75mm cover likely spec'd.

I see over the last few days also there's three 'erberts who apparently don't need to wear hard hat's (on religious grounds?). And the big fella in the crimson headgear doesn't look too busy.  I know I shouldn't take the mickey, but sometimes you have to have some fun, being on the other side of the fence for a change...

JukeBox beat me to answer.

Loops are to be fitted, to the other edges,I also thought it maybe lifted.

If you look at the artists impression, you will see two new walls, that appear to be an integral part of the raft,

I have chosen a few photos to shew you of this morning's visit,with Nigel, DoverMarina.com

 

These are from the camera, before I do the main upload to Flickr.

 

0830-0900.today.

 

They are now setting out on the concrete pour of yesterday.

 

What was thought to be setting on wood block,is now, not so, it's metal.

 

Another early morning delivery of rebar, was on going,from a lorry.

Interesting way of laying the rebar. They didn't do that at Fan Bay when we dig out the plant room the supposed to be bomb resistant roof the rebar had sunk to the bottom when they poured the concrete.

Hope they've got a lightning conductor on that crane, David; it looks as though you're getting a bit of a storm over Dover way.

Yes,thunder rattle around the valleys for an hour or so, not long cleared, suns out again.

 

Doubt I will be visiting site Friday, as it is River Dour clean, volunteer day.
