Issues related to the expansion of changes in storage tank foundations
Thread Content
Will expanding the already piloted tank foundation have an impact on future material loading, and will it affect the foundation itself? The original storage tank was 400 m3, and it is to be expanded to 2000 m3 on this basis. :$ The design institute is currently in the process of design, and I would like to ask the seniors from Haichuan Civil Engineering Structures.
Does the poster mean that the foundation has just had its piles driven in and the upper structure hasn’t been built yet, and now they want to expand the foundation? It should work. It’s no different from laying a new foundation.
Thank you! That’s right; the original design was based on the old tank foundation. Due to issues with material storage, it became necessary to increase the size of the storage tank, and since the foundation has already been poured, it is now necessary to modify it. The storage tank is not seated on a foundation.
Ah. The foundation has been completed but not yet used; it needs to be changed. But I don’t know what the specific situation is? What piles? What is the foundation for the upper part? If not handled properly, it won’t be a new foundation; it will become a modified foundation instead. But you can rest assured that it should have no impact on future material installation. No matter how it is modified, it will meet the load-bearing requirements for the upper equipment.
What the poster means is to add an additional ring-shaped foundation around the existing small foundation; of course, efforts will be made to integrate them together. A few more piles will be needed, and the design institute will take into account how to arrange them. I think the key issue is still foundation settlement.
There should be no problem; increasing the size of the tank inevitably requires expanding the foundation. The original foundation piles have already been installed, and by incorporating cross-shaped hidden beams within the modified foundation slab, this issue should be solvable.
The original poster’s question would be better clarified; it’s difficult to say anything in the case of a circular (spherical) liquid tank. According to pressure testing standards, the value is 2000 T, and the issue lies in the connection between the cross beam placed in the middle and the existing foundation. But with professional design institutes handling the design, there will be a way. Horizontal tanks don’t matter in that case. (For reference)
Thank you to all the professionals up there for their detailed explanations. I will bring these suggestions up when discussing them with the relevant personnel at the design institute. Many thanks to my friends from Haichuan: hug:
The foundation needs to have its load calculations done again, and the value resulting from this expansion is quite large.
