downsouth 7,143 Posted September 4, 2018 Report Share Posted September 4, 2018 Been on a refresher course for my deep excavation and shuttering tickets today and we were going through battering back/angle or repose in different soil types and the weight of moving soil at different depths if a side comes in and it really got me thinking about some of the dodgy/dangerous situations ive put myself in out digging and at work over the years.Any of you lads had any near misses or know anyone whos come unstuck over the years. 2 Quote Link to post
rob284 1,682 Posted September 4, 2018 Report Share Posted September 4, 2018 Yeah was out digging with my father and got a mark at 10 ft on a place we had dug a few times. Solid clay for 4 foot the hit a large boulder, must have been 5ft in diameter. We had to start a new dig and dig beside it. Again we had about 5 ft of dry hard clay and then 5ft of the softest sand under this clay where the sett was burrowed. Once we got the right depth we tunnelled is under the rock as the rock was burried in hard clay and wasn’t budging. Near the end my father jumps in and pulls the dog out stretched under the boulder, passed me the dog and as he jumps out of the dig the boulder collapses. We were both speechless and a bit shook for a while after it, could have ended very differently. Always dug the place at 10 ft plus then someone came on without permission and had what looked like a tiny dog at no more than 4ft, Sod’s law. 1 1 Quote Link to post
Rabbit Hunter 6,613 Posted September 4, 2018 Report Share Posted September 4, 2018 The only real bad one I've had was on a Boxing Day dig to a fox a few seasons back in an empty man made lagoon. The mark was 16 ft but it was all sand so easy enough digging, half way down my mate asked if I'd be ok to carry on while he went for drinks etc and to meet another lad to bring back to help us, I said no problem, I carried on alone while they were gone, once they came back we werent far from breaking through, broke through not long after and as I got down on my knees to look up the tube I heard the lads shout and as I stood up half the dig collapsed right up above my waist and they quickly jumped in and heaved me out. From then on every time we tried to dig it kept collapsing in and in the end the farmer got the jcb and dug it, luckily we got to the dog( just starting to go into shock from the cold) and the dead fox in front of him. But as I'm getting older and think about it on the odd occasion, I shudder at the thought of being alone and it collapsing on me or not hearing the lads and being buried as it gave way, it can be a dodgy game sometimes. 6 Quote Link to post
downsouth 7,143 Posted September 4, 2018 Author Report Share Posted September 4, 2018 We were shown a chart today and at 4ft deep if you take one side of a dig back at a 45degree angle that will weigh 0.8 of a tonne.If that soil is moving/sliding that weight doubles on impact.Now if you have 400kg on your chest you are not breathing in and have a minute if your lucky before you're dead.Certainly makes you think when youre kneeling or laying down in rhe bottom of a dig.

Naughty shit..... Anything over a metre we have to use trench shoring on site these days... Ive been down 4 m laying concrete storm pipes and front came in as machine driver was inserting metal road plate at front of box.... Lucky im a skinny c**t because i dived and flew up the pipe over the laser and crawled 60 odd metres back to the manhole....... Shit my pants to be fair. As i get older im starting to think about another trade.... As for digging to a terrier.... We have all taken risks, part and parcel of what we love Quote Link to post
downsouth 7,143 Posted September 5, 2018 Author Report Share Posted September 5, 2018 Same here mate anything over a meter.Im ticketed to do timber and steele shuttering down to 5meters.I used to think they were taking the piss when they made us shutter stuff up at a meter and move all spoil right away from the hole but when you've been on the coursed and seen the videos and photos and theyve explained exactly how different grounds react it definitely makes you think about some of the sotuations youve put yourself in out with the dogs and at work in the past. 1 Quote Link to post
Rat face 1,655 Posted September 6, 2018 Report Share Posted September 6, 2018 We was on a deep one a few weeks back in very loose sand. My arse fell out I must admit. We was down at 6m and looking down at my mate in the bottom thinking if this gose. It's game over for him 1 Quote Link to post
