As part of a larger housing estate development project I had to bust out a large piece of hard Granite rock to make way for underground services. This is not difficult when you can blast it but on this occasion we were working near a live fiber optic cable and probably blasting was not a really good idea... Expando chemical cracking agent to the rescue again - drill, mix, pour, break.

Telstra/NBN cable/conduit, etc. is rare to be covered or surrounded by anything, some of the stuff even runs through the tree tops, tree roots, and on top of rocky ground fully exposed. Although it's quite tough it doesn't like to be bent at sharp angles.

@demolitiondavedrillandblast Год назад

Yeah... such a high value asset often gets just buried unprotected in the ground, I have seen that as you say, crazy

@Michael-rg7mx Год назад

The cable itself isn't the great value. It is all of the user's downtime. They put a machine on each end to send signals, then plug on splices. The one we cut was up in a day. The locator didn't mark it.

@RolandElliottFirstG Год назад

Some of those locators are rookies and others are just to lazy to be careful and mark out with accuracy, over half don't even know the correct colours that should be marked to identify the assets.@@Michael-rg7mx

First of all, I just want to say that I really appreciate your channel, every one of your videos has been a pleasant, relaxing watch with an excellent sprinkle of humor and technical information which is just what my brain loves 😊 Cracking goo is fascinating to me and I'm curious how/why it expands outwards forcefully enough to crack the rock rather than just expanding upwards to ooze out of the open hole? It seems like expanding up would be the path of least resistance, so how does it exert any force at all on the sides of the hole?

@demolitiondavedrillandblast Год назад

Good question, it first hardens and then continues to expand.

Hello Dave, another masterpiece. I always like seeing another guy my age run a sinker drill well. We now have new requirements for blasting near gas lines. Any blasting within 500 feet of any gas line requires a pre, and post blast survey by the gas company, plus independent monitoring from a gas company required third party vendor. Something smells fishy. Usually takes a month to get it all together.

@demolitiondavedrillandblast Год назад

500 Feet!!!! oh... for goodness sake. Saddest part of the whole thing is that you end up forking out good money so other clowns can waste your time. Yeah... I had a bit of practice on these drills, I'm on air compressor #6 and this one has a lot of hours on it now.

9:45 Wouldn't it be more productive if you laid a mat on top of the rock, then the dirt? Wouldn't that make the rock easier to remove after the explosion, (minimal dirt mixed with rock?) And at 21:55, imagine in a few thousand years they'll be scratching their heads wondering how that was done.

@demolitiondavedrillandblast Год назад

I have a heap of light weight blast mats, but I need to bring them to the job on a truck which costs money, the soil is already there and I can do much bigger shots than I would if I only used blast mats. The soil also gives a higher level of protection and cuts the noise down drastically where the mats do little for the noise. The blast noise brings complaints and spectators that I don't need. Another bonus of using soil is that I no longer spend my weekends repairing blast mats.

@davewood406 Год назад

Unpopular opinion: having worked with fiber optics for decades, unless your shot went really wrong, it probably would have been fine. Even if it wasn't, the whole span being exposed, it would have been cheaper to fix it than the measures taken to protect it.

Hi Dave, I was wondering why you always use the dust extractor, even when there are big excavators creating even more dust than you are producing? Also wondered if a face mask with a powered filter might be more comfortable than the old gas mask?

@mozismobile Год назад

Guessing that it's because silicosis is a cumulative exposure problem. But that's a risk factor - some people are unlucky and develop problems at low exposure, others can, as with a similar issue "smoke all their lives and live to 100". Dave seemingly doesn't want to rely on getting lucky. (guessing thatt's the old bold thing... there's old explosives users, and bold explosives users, but there's no old bold explosives users)

@demolitiondavedrillandblast Год назад

That old gas mask is the finest unit on the market, It has a organic vapors canister and a P3 particle filter canister. When you see the WHO dealing with Ebola cases, this is the mask they will be using every time. This unit exceeds the P3/N99 rating. It is actually very comfortable - I recon I could sleep in it.

Which creates more force? Hydraulic or chemical?

@demolitiondavedrillandblast 6 месяцев назад

A good question to which I'm not really sure of the answer. I would think that the hydraulic splitter wins here because its force is only acting for the depth of hole that is equal to the length of the wedges (450mm) and If I were to use holes only that deep for the chemical I would not expect as much action.

What? The title is Breaking more hard Granite without explosives and explosives were used What?

@demolitiondavedrillandblast 11 месяцев назад

Only in the latter part of the job, the rock featured in the thumbnail was completely broken without explosives.

Do you have a video demonstrating how the epando works? Like pouring in a PVC tube or maybe a coffee mug or old piece of pottery?

@demolitiondavedrillandblast Год назад

No, I have Two time lapse videos of it in rock though, here is one - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-04y4k8bJMns.htmlsi=OTk9KHQo6plnTZC2

@@demolitiondavedrillandblast Thanks Dave. The ancient Egyptians could have done with some of your equipment, especially this stuff. They got by pretty well with wooden stakes but google won't tell me what type of wood they used.

There is more than a few things that we are yet to learn about their methods.

i’m impressed at how well controlled your demolitions are. it’s like you wouldn’t crack an egg on top of the demolition site during the deterioration.

Thanks Paul, you obviously have not watched this one - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Z9N-kRYlOz8.htmlsi=Gc8UX3KLjmEZiZ02

@@demolitiondavedrillandblast I would honestly counter, that while the example given would have cracked an egg...I second Paul's sentiment...it was perfectly controlled. Nobody got hurt...well OK, one Magpie got a concussion, but he was able to fly away so no harm done. Rock needed to go = Rock Gone. 🙂

@keithmoore5306 Год назад

you need a license for the goo down there Dave, up here the excavating contractors do goo jobs! i don't see how that stuff works it seems to me with nothing holding it in the hole it'd just push up out of the hole and do nothing!

@demolitiondavedrillandblast Год назад

No license required, not classified as dangerous goods. The goo first hardens and then expands.

@keithmoore5306 Год назад

@@demolitiondavedrillandblast still with no tamping you'd think it'd just boil out of the hole following the path of least resistance!

Yes, very glad about that as it was brand new.

Is the cracking agent lime based with some additive to aid carbonation like maybe soap?

@demolitiondavedrillandblast Год назад

Yes, mostly quicklime and several other minor ingredients.

Contains calcium oxide, ferric oxide, aluminum oxide.

@@demolitiondavedrillandblast that is interesting. they don't add silicone dioxide aka "sand" but instead use other type of "sandy" ceramic oxides.
