Poxy Weather

[TiltyShaun]

Not really the right thread but as I put the shaft sinking pic above thought I'd show progress so far stripped the soil then went about clearing out the shaft to see where the rock head was ended up 3.5m down to good ground View attachment 12224

Are these old mine shafts?

Yes was back filled long time ago but has Settled due to bad weather so needs capping

I can't believe how dry that is. I though everyone was getting wet weather at the moment.

Having built a site on a flood plain, I can tell you there are quite a few regulations to jump through and things are quite carefully considered. Or at least they were with the developer I worked for. We built 14 houses in Chertsey - the year Chertsey was underwater and the army had to be called in. I know what we did worked because we were under 2ft of water at one time! The regulations around not building up ground artificially, stopping foul pipes from backing up into the house and allowing the free flow of flood water around the houses was all thought out and a necessity of the planning. Just so happens the one in 100 year flood event happened the year we were building it. So it is thought about when planning is granted on these higher risk land parcels, it just might not be enough.

I think what we are experiencing is beyond what those in the planning department/ environment agency foresaw and lessons will be learnt from this winter. The question is, how high do we build the defences because if this constant wet weather is to become a regular occurrence, there's no point building them to this years watermark - they almost need doubling. I know the EA are investing in improving flood defence as I've been asked to tender for some of the jobs. This was before this winters rain. So it is happening, just without the fanfare the papers expect.

The pictures below show some of the details we had to incorporate into the build. The oversite had a 450mm void under the floor with "vents" to allow flood water to enter under the building and recede without causing any damage. The floors of the void were concreted and laid to falls to allow the water to flow out. Even the perimeter wall had vents in to allow water to flow through. It was all thought out.

no one in their right mind is going to buy any of those ..... WTF is going to insure them for starters ??? as said the voids are simply going to fill ..attract vermin, etc. ..... been a few round here built on raised mounds, where there's a risk, as a lot are in Europe ... any risk and they're raised maybe 10 feet .... has certainly worked fine in a lot of locations

my old w/shop site was a nightmare for perceived flood risk, even though it'd never flooded in living memory, EA dictated it was right on the edge of a 1:1000 yr event risk zone, so whole acre site was raised by two feet, despite the fact that:-

it was already 5 feet above the surrounding area (no topographic study done on the ground - all LIDAR mapping)
and
I had photographs of flooding from '78, which was the worst Aber has ever seen in living memory, 4 feet below their predicted high water map.
Plus; there had been a massive flood prevention scheme undertaken, in the late 70's, re-routing the main contributory watercourse, away from the town in a 12ft culvert, direct to the river ... they (EA) conveniently had no knowledge of it ... I knew the guy who was in charge of the project at the time for Welsh Water and went and photographed it all ... and had a lot of drawings, etc. for it, extracted from EA records

Basically the EA's .. (or whatever the tw*ts're called now) LIDAR based maps are so unrealistic they might as well burn them ... the flood risk map for Abergavenny shows most of the town under water, with the bits that aren't, at the lowest levels and the wettest bits 30-40 ft above them .... anyone with half a brain cell and some local knowledge can see how farcical they all are ...
I dare say that most other places have similar problems, that local knowledge'd recognise

Tuesday last thing looking at this job before starting Thursday was wet as hell but being not far from the coast any dryish weather plus a good onshore wind drys quick
Seams to soak the top couple inches and then run off rather than soak down into the ground old shaft fill had settled due to water in adits and stopes underground probably higher than normal
Got a little bit more to dig out Monday to finish till it's been concreted

A site in Matlock near me being cleared for houses that supposedly “only flooded twice in 75 years” at the planning meeting. This is second time in last 6 months!

Darley dale??

How much concrete will you lose in that hole

6 cube 400mm thick 2 layers of mesh

Nice interesting work, if that is clay tips in the background I have seen a couple shafts like that which have opened up in that area.

That's the sea at st Agnes

Used to go there every year caravanning with my grandparents. Used to have a great laugh at the carnival there - basically a huge waterfight.

Is there a spec to work to to do you just do it from experience?

There is different specs of slab and different specs for plug type as well

This is a concrete plug design

And this is what we are doing as each slab cap varies a bit due to size so excuse the hand draw it what mining chap gave me

There is limits to the plug one but slab ones just scale depending on the shaft size

 

[Grahams]

Always interesting to see what other people do - thanks

Beyond a joke today....Carr's went for a lean over up the lane from us...waiting for macadams, won't be cheap with water involved...then dragging BMW's out of the way...what is it with em? Seem to have a death wish round here at the moment. Must have counted 10 drowned in last 2 weeks.

That Renfault won't like being in the water like that either :O

 

[Jimbo69]

We had some of the white stuff today. Hopefully it won’t stay long.

 

[Quattromike]

The white stuff is offering to lye on the ground a bit here now. I hope it jumps 10 degrees during the night, I'm heading to Stirling in the morning and the A9 is slow as F# with a bit of white about
