Concrete panels as bridge?

[dgjeynes]

We’ve got to put a new bridge in over our brook. We’ve already got 4 old large rsjs. Looking to lay them across then put panels flat down on them running cross ways anybody ever done something similar?

 

[Sharpy]

No, but when I asked a local panel supplier for a solid tank cover they suggested using slats and concreteing over them.

Think @ColinV6 has done something similar

Personally would not do it. Have had 4mtr x 1 mtr concrete panel bog mats crumble and disintegrate. Went back to panel manucaturer and redesigned bog mats to also include steel mesh in addition to the tension steels. These have been excellent.

How thick are your bog mats?

 

[ColinV6]

How wide a span are we talking here?

Crocodile Dundee moment coming up



That’s not a bridge this is a bridge

 

[dgjeynes]

How wide a span are we talking here?

We’re spanning approximately 20ft

I suppose it's all about context.
How wide is the brook?
How big are the RSJs?
What do you want to run over the bridge?
How often do you use it?
How secure are the banks?
Sorry for all the questions, but the answer to your question is yes it could work if . . .

This all needs answered first before we could possibly advise
Also, whatever your budget... double it

Bog mats are 100mm thick

^^This, lots of variables that need to be answers before you can know for certain it would work for your situation. Big one that will affect the concrete panel is how wide do you want the bridge? This will determine the beam spacing and hence how far the concrete panel has to span. Defiantly possible to do, I see quite a few bridges with concrete decks with either steel or timber beams.

We did this 14 years ago. Old railway bridge. The sleepers are laid on 6 heavy duty girders and have a light covering of railway ballast.

 

[onesiedale]

Why did you put the sleepers rough side up?

You put them wrong way up. Other way up and some baler band threw them hole and tied down to girders and jobs a goodun

Did you drive tractor along girders to put the first sleepers down

 

[Highland Mule]

Why did you put the sleepers rough side up?

If I had to guess...

6 heavy duty girders

To spread the load evenly across all the girders.

 

[7610 super q]

Should imagine he just pushed them across......

 

[Bongodog]

Why did you put the sleepers rough side up?

if they were the other way up, the middle wouldn't be supported and then they would crack.

 

[robs1]

While concrete sleepers would never break as they are very strong they are also extremely heavy
