This is an extremely dangerous. Almost a suicidal method is digging a well in Pakistan.

This was a common way of sinking a shaft in the 18/19th century in industrialised nations.

Dangerous, yes, I have seen this method in some of the most modern systems. True that was with cranes, hydraulics, and automation but it was the same idea, have a ring at the bottom (steel, sharpened like a giant blade) then excavate just like these guys, and slide it down.

I’ve built modern metro stations pretty much like this. Except we use shotcrete (projected reinforcement concrete) instead of bricks. And obviosiy more safety gear. We built 60m deep and 40m wide shafts with this method

If you know anything about construction or physics, you'll know this is perfectly safe. Backbreaking, but safe

It's dangerous given that u don't know what u're doing..people dug wells that way for hundreds of years, and most of the diggers died from old age,not from accidents. Last time I saw this method used in 1999, I was a teen back then and three middle aged dudes built well in a week

Its how the supporting caissons for the brooklin bridge were built.....into the riverbed.

Given it is dangerus It seems to spark an effect of natural selection sss All the shit brick layers become mud diggers sss All the shit mud diggers become no ones next problem. Repeat jntil only the skilled remain and you got dedicated masters lf ghe craft roaming the lands making working wells ssss

I've done a couple of these, we call it a sinking Caisson. Reinforced concrete is the building material used and it's dug out by a mini excavator which loads dirt into a crane basket.

Smart technique

We had a 150-ft well dug by a local in Nicaragua, and it was like this except concrete block to about 15 ft down and beyond that just a perfectly round hole in the volcanic dirt. Also only about 4 feet wide. Pulley at the top and a guy on a horse to pull up the bucket of dirt/gravel as well as to lower and raise the guy each day.

It used to be common in America.

Yeah? But the guy that gets crushed gets double pay.

@grok looks like they know what they’re doing Probably more morbidly from texting and driving Or super processed American foods

Well at least they can do it without @MrBeast

They have a LOT of expendables.

I don’t understand nigeria people …I don’t know what kind of ideal they have come up with ….this people have been doing it for years if it’s dangerous they won’t do such which kind dodoyo be this in suit

Hey @grok what's the story here

Yes

潜函工法

It's an almost extinct technique now for water drawing from Well with the advent of new techniques using modern tools for surface boring. Earlier well was prepared, boring done at the bottom of well. There're 2 types of wells 1: brick walls 2: self sustained soil walls.

Amazing, dibs on the supervisors job managing the work from the top of the well

it is actually not dangerous nor suicidal. best wishes from a structural engineer 👋

Bottom has no solid ring still I see bricks - how come its staying together and not going down uneven?

It's mind boggling that a no mortar dry stacked bricks don't completely crumble as it goes down into the ground bit by bit. I hope the guys digging at the bottom are getting a little extra pay for the risk they're taking🙄

Чем он опасен? Всегда так делают.

So cleaver

I lowered a small shed using that method. I worked N, S, E and W and then NE, SW, SE and NW etc. Yes, it does look extremely dangerous and would rely, at least in part, on the bond (strength) between the bricks, starting at the top. The ground I worked on was (stable) mudstone.

You wouldn’t want it dropping on your foot

It's sand, and they are above the water table

Wow

This is how they dug the Channel Tunnel using the high volume of immigration in the UK
