Trenching across a backyard

The sewer outlet from the new subdivision had to connect into and existing pit that just happened to be on a neighbors property. This meant digging up the yard to lay a pipe and we knew that it was very likely to be rock there and that it would have to be blasted. Fortunately the rock did not continue right up to the existing pit that was very close to the house.

That tin shed is about 5cm higher than it used to be!

Shhhh....

For once a job that sucks. Turns out to be a good thing. You always know the right way to smack rock. Merry Christmas to All.

Im a big advocate of vacuuming, ive had lots of “are you mad?””are you soft” When sucking sawdust from customer lawns/driveways/patios, or vac’ing rather than sweeping up, i like my lungs ta…. And a decent wet vac is beter than any mop. 👍🇬🇧👍

[@robertgeorgewerner]

I love my tiny shop vac for cleaning up little jobs around the house. Glad to see the big brothers are even more useful than we thought.

[@demolitiondavedrillandblast]

Oh yeah! this one has a pair of motors that you would find one of in a home ducted vac system.

[@robertgeorgewerner]

@@demolitiondavedrillandblast So much better to suck than to blow! Makes both a raunchy joke and a great safety campaign slogan.

Brilliant work as always! A little sad we didn't get foitage of the dig out, but still 2 Thumbs up for the video!!! Thanks for sharing 🇨🇦

Glad you enjoyed it, they have still not dug it out.

Love it Dave, dunno where ya find the time to do the work and upload videos, kudo to you ya hard working Aussie !!!!

[@frozenjoe6313]

Must be a pretty powerful vacuum and a great idea to suck the slop out............. Its always nice to see a perfect balance between the powder breaking rock and the shot just lifting up the cover a foot or two. Perfect.

[@demolitiondavedrillandblast]

The vac has a pair of the motors that you would find in a home ducted system Joe.

[@frozenjoe6313]

That is really impressive. I did a little looking and thinking, and research on those very strong home vacuum power units. And just 1 of the stronger home units is rated at a maximum water lift of 140 feet or so, and you have 2 hooked together.. Around here there are a few giant vacuum trucks with vacuum hoses the operators use to actually dig holes in gravel or whatever after they jackhammer through the hard road surface ... I dont know if you built it or bought it but either way thats a really nice piece of equipment you have , very useful.................... I am jealous .@@demolitiondavedrillandblast

Hey Mr. Dave I guess you know that using a vacuum cleaner sucks! Also that the life of a vacuum sucks unless you hook it up the other way then it blows. Merry Christmas and Happy New Year Sir and to all of your family and crew.

[@keithmoore5306]

pretty easy job on this one compared to some you've had this year!! planning to end the year with a good bang?

[@richwielechowski5191]

Good day Dave. As the old saying does, necessity is the mother of invention. Love the trenching shots. Thanks for sharing. Stay safe and Merry Christmas to you and your family.

Thanks for watching Rich.

[@jeffgordon9549]

It's crazy how close they are building to the 220kV transmission these days... used to require a 50-100m exclusion zone either side..

[@demolitiondavedrillandblast]

Some countries have much larger exclusion zones.

good one mate

[@cosmopezzolla996]

Brilliant innovation with the suction line! Anyone who has had to blow out wet holes was taking note of that one........aka me 😂......I haven't got the additional pre-separator yet though so i think I'm out of luck for now.... one of these days. Do you find a lot more longevity out of your filters using it Dave? They are a bit pricey.

[@demolitiondavedrillandblast]

Glad you liked it! You can make your own cyclone separator. Yes the filters in the vac rarely need any attention when I use this pre-separator, The post separator vac hose last a lot longer also before it wares out!

Always enjoy watching trenching but for sure, some nuisance problems with that - particularly when holes get wet so quick - total PITA!. Nice idea vacuuming. Holes look about 3M deep. Nice work Dave :)

[@demolitiondavedrillandblast]

Totally agree, of course there is a limit to how deep I can vac the water.

[@longlat39]

Always look forward to your blasting work Dave, but not seeing the dig out is like reading a novel that has the last chapter deleted.

[@demolitiondavedrillandblast]

Sorry, they were not in a hurry to dig it out, last I heard they have still not done it.

[@ronmccabe7164]

Wow! Are you sure you didn't punch through to the Atlantic?

[@tugboat2739]

Howdy demo Dave

[@andrewclarkehomeimprovement]

Nice one Dave, the sucky pipe is also better because if you blow water and slop out, some of it will stick to the sides of the hole or wedge up the outside of the pipe and run back in. Anyway, just want to wish you and yours a very merry Christmas and a happy New year. Looks like 2024 is going to be busy for both of us, mine perhaps a little less explosively (I hope)!

Dave says " OK 25 hole shot" . Rabbit exits to the right.

[@lukahierl9857]

Maby the rabbit exited in all directions simultaniosly.

[@johnmcclelland5265]

Dave I know nothing about this work. When you detonate I see a flash along the uncovered detonator cord. Is this just because the cord is not insulated? And if so why not? Is it just cost? Thank you for making the videos. It’s great to see work you would never get to see in normal humdrum life. Merry Christmas.

[@demolitiondavedrillandblast]

The flash that you see in inside a very thin plastic tube that is called signal tube or shock tube, this technique allows the shot to be fired with any wires electrical circuitry and eliminates all of the associated risks.

[@tiredoldmechanic1791]

Isn't there a way to use the air compressor to create a siphon to clear the holes and blow the debris out away from the holes? Maybe that's already the way your vacuum works. Happy blasting!

[@demolitiondavedrillandblast]

I have been thinking about making a venturi system for this.

[@ralphdeemie4916]

Great job as you always do! Is it getting hot down there?

I must say, I do sometimes wonder how much all that explosive must cost? Dave sure gets through a lot of it.

[@gettogo0159]

@@TrevorDennis100 In the end if the customer want the job done right, they'll be paying given it's explosives aka... government over sight if you cut corners you'll be having big issues plus the rest. Dave does it right within a safe limit. Remember AUS doesn't like people with knowledge of self defence/private owned firearms/fending off PTB's (returning the pain/favour) when the person/s used legal self defence. They near banned private firearm ownership.... yet criminals get them easy but the legal ownership have no chance!

[@rexjames0015]

Scott you mean "explosive" don't you?

[@leonardwalker8700]

Good Morning Dave, Do you still use your Kobelco Excavator Drill Rig?

[@demolitiondavedrillandblast]

Yes I do! Video of this in action is coming soon Leonard. It was parked up for a while because my old Hino tilt tray truck had a gearbox failure and I was unable to get a replacement part for it, In the end I had a part made for it but this took a little while.

[@Je.Suis.Flaneur]

I imagine that you could get a much stronger vacuum pump and put a T into the tube and use the venturi effect to suck without having that long flex hose on top and it would make the assembly less top heavy and awkward to hold. But someone smarter than me will have to calculate the vacuum and horsepower necessary to achieve the same or greater suctions. Thank you for such an interesting video, Dave.

[@demolitiondavedrillandblast]

I have been thinking about this very thing.

Yikes, living in that HT/EM field with all those pylons would put paid to any HAM radio hobbies.... & i expect the florescent tubes lighting in the garage won't even need being wired to Mains...

[@demolitiondavedrillandblast]

You got that right Pete. If I lived there I would be bundling up every ferrite rod that I could find and trying to suck some of that power out of the air. Are you a Ham? I am.

[@peteb2]

@@demolitiondavedrillandblast Not a HAM yet Dave but i really want to look into it for my retirement which is not far away. Been in electronics all my career, played around with radio stuff since a kid & have a hoard of old comms receivers to restore. Get into a bit of black powder canon as a hobby so why i like your work in your videos.There was a farmer in the South Island here in NZ who'd set his milking shed up to free power from the Nation Grid feeds strung across his land. The power authorities found out & sited excessive Power Factor losses on their feeders whenever he milked his heard twice daily & made him pay. I doubt they could not prove it with measurements on a complex 220KV bearer in the Network & just says how they think....

If you have been in electronics all your career, you should have no problems getting a license Pete.
