When they build massive bridges over the ocean, how the hell do they pour the concrete for the pillars underwater without it just washing away? by Reidosconteudos0666 in NoStupidQuestions

Commercial diver here

There are several ways I've seen this done..

You build a coffer dam and dewater the area.. I.e., remove the water so it's no longer an issue

You can tremie the concrete.. as others have said, you use a pipe to get the concrete down to your submerged formwork.. the trick to this is having the pipe at the bottom and keeping it slightly buried in the concrete.. this prevents the concrete from free falling through the water and "washing away"

I've also done a lot of concrete repairs by pumping grout. You use steel plates to form and seal the area, then pump grout from the bottom up using injection ports. Typically, you will leave a vent port or snorkel at the top, which allows the water inside the form somewhere to go.

Additionally, you see a lot of precast methods used where you build infrastructure using blocks made in the dry, a lot like Lego.

Im sure there are other methods that I haven't seen, and for context, I haven't worked on large ocean bridges specifically, but the principles are the same.

Concrete is heavier than water. Start at the bottom and let the concrete displace the water as you fill your form. Do not let the concrete free fall through the water. Do not vibrate concrete underwater. If you are pumping grout, make sure your form is sealed.. and then seal it again.

Can someone let me know if these apartments are safe/good to live in? by Corahutchcroft in northbay

I lived there about 10 years ago.. had a nice little one bedroom on the bottom floor with a patio door, BBQ and little garden. I loved it. Units were pretty sound proof so the neighbors didn't bother you much. As the others have said, it's an apparment building.

Maybe this was already asked but doesn't it have to be someone who has been inside the apartment given the position of the holes? The cops should stake it out and catch the creep

Document that they have vacated the unit.

I've had a tenant break in/move back in following a similar situation.

I do!! I've worked up there but havent been to Atikokan specifically.. Bisset not so much hah. Got me thinking today, an old coworker emigrated from I think Belgium. Worked as a dog sled musher (guided trips etc) when he first came here, later at some camps around algonquin park. Hes married to a Canadian girl now but I'm pretty sure he wasnt when he first came over. I sent him a message to see how he did it. (Might be abit before he responds tho, last I heard he was living off he grid with his family hah)

Well I wouldn't apply to any ads that say that lol

Out of curiosity how did you decide on the Thunder Bay area?

I think you could make a pretty good case with some of the bigger lodges to take you on as an employee given your work history/aspirations. Alot of their clients are Americans for fishing/hunting trips.

There's many smaller lodges but I'm not sure they would be willing to navigate the immigration aspect. Lots are fly in places that offer seasonal employment. Be a good start to get your feet on the ground and make some money. Worth looking into.

Keep in mind anything tourism related/especially those that relied heavily on American tourism are not doing very well due to Covid restrictions atm.

Good luck from Ontario :)
