Full step-by-step video of line-pumping a boat ramp through 500’ of hose. Hot concrete created a few tense movements come time to blowout the lines at the end of the pour.
Such a great video to watch! We have done similar jobs here in New Zealand but use cement instead of bentonite so that any slurry excess can be lost in the bottom of the job without compromising strength, it just means we don't slurry up until the concrete arrives, then it's all go! Everything else is so true when "the kids are in charge!" Cheers!
Thank you brother! And yes, for the cost, I’d venture to say bentonite is one of the most effective tools us line-pumpers could ever keep on the truck 👍🏼
Thanks brotha. This project has come a long way in the year and a bit since this very first pour. Can’t wait to do a walk around of the finished build.
It was good to come back and watch this video. I was looking forward to seeing how things worked out for you with the tide. Curious question about the Concrete Trucks you guys have there ? I think I heard 9 Cubic Yards on 1 truck 🤔 It's interesting to see how things compare in the Concrete industry from one country to another. The largest rigid Concrete Truck we have is 9 Cubic Metres with a few Semi Trailer version going up to 11.5, which is a lot of Concrete. Thanks for bringing us along for another day out on the job 👍
@@weldmachine The the common mixer trucks in our area (tandem steer/tandem drive with booster/drop-axle) can carry up to 10.5 cubic meters. They often carry less if it’s a specified plasticized/wet slump from the plant, or like in this case, they have to traverse steep grades during travel to the job site.Maximum load size for this specific site is 9 cubic meters in these trucks. It’s been very cool seeing this home transpire from the ground up. It’s now getting to the phase where things are really going to transform/take shape. Can’t wait to show the final product, she’s going to be a beauty for sure!!! Appreciate you watching and partaking in the comments. Pump on bother 👊👊👊
I also use a "Rabbit" what we call it on the west coast, when pumping down hill. Which is a empty paper cement bag or anything paper on the site that is smashed into a ball that will fit in the hose coming right off the back of the pump. Hammer that sucker in tight into the hose! Its seems like the paper might plug the hose but the pump blows it past like nothing! I've never separated doing this even pumping down a straight cliff 6 ft off the pump, cheers
So I’ve tried that serval times using a sponge and never had much success. I swear that the type of sand used in our mixes out here causes them to behave differently.
We poured dozens of those over about 5 summers at a big resort. We were pouring right under water.9sack with enough cchloride that it would set up in our chutes. Same guys did it that repaired a long stretch of interstate by us two years before. Same mix on a hot day on concrete. I felt bad for the finishers. They’d roll it with a 8 ft wide air roller,screed it if they could and brush it. They be driving on it that night.
I always get nervous when loading up a long run of line like this with a “spicey” mix. One of those situations when we make note of the fine print “sign here please” 😂
I line pump in California and I never use slicks to prime out. All I put is about 10 gallons of water for prime and I never plugged on prime, even with 300ft out. But hey, to each their own! Cool channel.
So you’ve actually inspired me to finally to a water-prime video. With our mixes out here it just hasn’t ever worked. I’m gong to post up this video in. Week or two. Hopefully you’ll have time to watch it and let me know in the comments what it is that we could possibly be doing incorrectly. I’m convinced it’s the coarseness of sand which is used in our material.
@@canadianconcretepumper1979bonjour de Belgique 👋 Je confirme que chez nous, amorcé a l'eau ne fonctionne pas car nos mélange son trop maigre en ciment 😑 Merci pour votre travail camarade opérateur 🇧🇪🇺🇲🇨🇦
On Job's like that going downhill I put a little water in the line then I use some wet Newspaper in the line not too tight and then pour my primary in and that stop's it running away. That's how I've done it for year's here in Ireland and never have any problems.
I’ve tried the sponge ahead of the prime method a couple of times and failed miserably. My thought is that the sponge was just too tight. I like your suggestion of not too tight, wet newspaper. Definitely going to give that one a try! Thank you for watching and commenting 🙏
Will definitely have more videos from this project. We have to come up with a way to pour 150 cubic meters into a raft slab which the main house structure will be built on.
I can’t imagine how many permits a job like this must take! It would be many years in Seattle / Washington. A friend took over 10 years to build his boat dock on Puget Sound.
This property is worth an astronomical dollar value because it’s actually grandfathered in as having its own private dock. Even so, I’m sure there was a crazy amount of hoops to jump through in order to get things to this stage. They did actually have an environmental liaison keeping watch as it was poured. Next impossible to obtain permitting for building similar on a property in which it wasn’t pre-existing, as you had eluded to.
Ese truck estaba un poco incómodo que bien que llegó la VS para alimentar la 60 hp muy bien en mi país Colombia trabajamos con tubería de 125 mm no con mangueras no les gusta alos operadores de botón por qué no saben más solo botones .me gustó ese vídeo Scott muy bien
I’ve been training on a boom in Southern California and even when I was line pumping I’ve never seen a pump, pump into another pump. What’s the reasoning behind that? Curious.
Keeps the pressures down, makes for easier pumping, let’s us pump a drier slump for the placing crew to work with on a slope like this, helps to keep volume up without having the line jumping around. For us it makes more sense to use the two pumps and have a quick setup and takedown versus using one pump and dealing with the time/labour required to setup larger diameter hardline. This is just one of those jobs where it really made sense for us.
16.5 hours last night in Calgary, one truck at at time 120 meters. Started the day off with a house floor in Red Deer. 7 till 11.30 one red bull lol. Sausage an eggy time and taking the nieces out on the lake😎
It’s the same out here right now with the current shortage of supply. We’ve been working all kinds of crazy hours. Nice that you got the Saturday off to enjoy with family. Enjoy the day brother!
Thank you for watching my man. Couple of years back I hit my mid-life crisis and decided that I’d become a professional bodybuilder, but that’s a whole other video on it’s own 😂😂😂.
@@canadianconcretepumper1979 Also have to comment on your tip last time around I asked about the hose cleaning. The fill and roll cleaned 'em beautifully. Now I never have to dose myself in a high pressure stream of water out the side of my boom pump 😂 Would love a video on your bodybuilding, being into fitness myself. Amazing content, never stop! Love from Norway
@@canadianconcretepumper1979 It sure dose help. I run a 50 on Vancouver Island. Just came across your channel scrolling. I know the video was old But had to mention the bags. its good trick
That’s a good suggestion which I get quite often in the comments section. We’ve tried that technique a few times, and for whatever reason (perhaps the mix designs in our area) it rarely makes it through more than about 2 lengths of hose before dry-packing. One of these days I’m going to try it in a video just to show the results and see if any of the viewers have any tips as to what we may be doing incorrectly.
@@styzr on the last one I posted we used 5 buckets. The problem seems to be once it segregated it’s game over, regardless of the amount of bentonite. Can be difficult to find that prefect balance and get the bentonite mix just right.
We’ll run either a few pipes, or wire braided hoses off of the hopper. Most of the reputable brands have pressure ratings based on a 2:1 safety factor (eg: a hose rated for 1233 psi continuous pressure will have a maximum burst pressure rating of 2466 psi). Either way, it’s not ideal living in that safety factor zone. ConForms is now producing 150 bar snap clamps for this exact reason. Many trailer pumps are now producing well over 85 bar, so the stepped things up to accommodate.
Not unless the amount of water is crazy high, like 150 gallons per 10yds, basically unless the concrete is separating out from aggregate (rock). However there are ways around that such as super plasticizer which can basically double the allowed water content
@@austinpalmlund5054 yes I think even before it starts separating from the rock the added water will start to destroy the strength based on my research. And plasticizers is the only way to arrive at that exact PSI
Is that steel reinforced line BTW? I was told by a hose seller not to kink or pinch it anywhere as it would break or deteriorate the steel mesh in the lines. I see there are also fabric lines as well.
None of the stuff in this video is wire-braid. We have a couple lengths which we’ll as as the first hoses coming off of the hopper when pumping shotcrete, but aside from that we leave it back at the yard on the rack. It’s true what they’re telling you about not kinking it. Even with storing it incorrectly (at the bottom of the hose pipe) we’ve found that it gets flattened down and never really reverts back to iota original, round state.
Why was he not listen to you and adding water into his Hoppor while blowing into it because the wetter it is in the line the SAFER it is for blowing out plus it gives you time to set up for 2nd blow out.
I was waiting for this comment! You can here him say in the video that when he turns his water in it kills the agitator (pro tip: the water valve can be partially engaged as such that the agitator still turns, albeit more slowly) bloody kids these days!!! 😂😂😂
@@canadianconcretepumper1979 yep you can add a bit and turn the agitator on and off but if the concrete goes off in the line's and he has to hand empty them he will make sure its wet every time after that.
@@johnnytyrrell7060 operator says on this newer machine you can not achieve partial water/agitator simultaneously like we can on our older machines. Our newer booms with the toggle switches for water/agitator are the same. In this case I just fill a 5 gallon bucket with water and add to the hopper while recirculating.
4” is an offensive term around here with regards to line-pumping. Perhaps if we had been pushing big volume, but with a mix designed for 2” line and what ended up being only 27 cubic meters of it to pump, this was in my opinion most labour efficient way of getting this job done.
Also, you throw 4” line on and most all residential placing crews around here would quite literally up and leave. We’ve been spoiled with our 2” line friendly residential mixes.
It 100% helps, with our material. Leaves a thin film of bentonite slime in the hoses as well as fills the voids at each clamp/connection which would otherwise eat up a small bit of primer. Likely wouldn’t work as well with grout, but would still be of some benefit, IMO.
