Discussion
Hi, can you please advise on when a winner will be chosen, or if one as been already.
Thank you
Thank you
Hey Mark, would you rate my design? Thanks
Hi all,
Some really excellent efforts, due to the volume of design entries, and the similarity of many, it will take me a few days to work through all of them based on the original design parameters:
- Similarity to original design brief
- Functionaility in planned environment, robustness, Simplicity of design and ease of construction
- Quality of actual design once uploaded to Solidworks.
The top 5 designers will be invited to future blind design competitions.
Regards, Mark

Can please extend some more days. As i Looked the contest today.

Hi coldmonk,
In response to your questions:
1. The device will be fitted prior to driving the pile, so it will expand with hydraulic and driving motion, to the final 45deg expansion shape.
2. It will be retrieved, so the hydraulic pistons will be used to push the pile out at end of life, for re-use. That is the plan anyway :-)
Please feel free to ask any other questions you may have.
I have started the detailed review process and am currently downloading all designs into Solidworks for analysis.
Regards,
Mark

Hey Mark, so from what I&
;ve understood this device you&;re seeking will be used with steel pipe piles, correct?
Regarding this I have two queries viz
1) will the device be installed on the pipe prior to driving the pile or after it has been driven a bit.
2) is the device meant to be used multiple times or is it sacrificial in the sense that concrete will be poured over it as well thus making it a part of the foundation permanently.
I ask these as your request is rather novel.
Thanks

Hi Guys, lots of questions I will try and clarify with answers below:
1. No existing pictures it is a new system and new use. It needs to be run with the legs collapsed against the pile / pipe body. Then while running into place in very soft formation the hydraulic rams will extend the legs out to approximately 45 deg. You have freedom to come up with different hinge and leg extension mechanism, but overall the system must be able to fold flat against body, with total OD less than 60".
2. Loadings for the pile are tricky, installation loadings will have the hydraulic ram apply up to maximum of 10Mt of force on each leg. Service loadings on the system maybe up to 150 - 200 MT Axially through the pile (most of this will be taken through the pile) and 40 - 80 Mt applied laterally to the top of the pile.
3. The legs need to be able to fully collapse for easy of transport and picking up, the total assembly OD should be less than 60".
4. The legs should be able to withstand approx 100 kN m of bending force (the detailed engineering and design of these is not part of this competition)
5. If any one is able to undetake FEA, this would be a big benefit.

Hey Mark. Do you have more photos of the actual clamps on the pipes? Or of the materials being used on an existing system you are using? Just like to get a better idea of what you currently have (if anything?). Thanks - Chris
working on it.
Hi Mark,
I have a doubt about the point E in the part 3 is it able to move up and down if not will not be like top view assemble will be like the design I have sent. please contact me to discuss more. thanks

I need to know the application of the pile, so we can make the approximation regarding the lateral forces exerted on the pile, which will be transmitted to the support structure.
upload more illustration, please. I still don&;t get the idea of what do you want to build.

What&;s the point of the leg being able to be open-close?
;s the point of the leg being able to be open-close?
I got that the L length for the curve and the H for the rest as showing in part 1 . is that right ?
Hi mark , The length (L) of the part 3 for just the curve or for all the part ?
hello, is it necessary to make leg curved as shown in aerial view. can i make it straight?
Thanks,cause it was written explosion ,not exploded.
Hi Walxo, exploded view, is a different view of the component schematic, an illustration that shows all parts "exploded" from singular item.
Hi Mark.A few questions.
What that is mean ( Explosion diagram)?Is there any potential explosion risk?Is there any ATEX classification?Is it explosion hatch or not? What is the meaning of the pipe clamp?

Hi guys, thanks for taking time to look at this.
I will pre-pay and add a 2nd prize as well.
"3 parts" was just referencing trying to reduce different parts, to try and stadardise for simplicity. If there are more parts, but the design is better / simpler then that will be a good solution too.
Mitch, in response to your questions:
- This structure is to stabilise the pile as it is taking lateral loadings in shallow and weak soil conditions.
- the pile will be installed by crane
- The pipe within this device is the structural pile, it will be jetted into place or possibly installed in a predrilled hole and cemented.
Regards, Mark
