Discussion on storage tank design issues

How to deal with interference between the tank wall manhole reinforcement ring and the foot bolt seat? Should it be a reinforcement ring for the access hatch, or a shimming plate for the foundation bolt seat?
If the diameter difference is not significant, the diameter can be reduced by increasing the thickness of the reinforcing ring.
Agree with 2#: if the overlapping area is not large, try not to cut it at all; the reinforcement area can be increased by changing the thickness. Specific methods include: increasing the thickness of the reinforcement ring, increasing the thickness of the fitting, or replacing it with a forged part. :)
Opening reinforcement calculations are required to determine the size of the cutting reinforcement ring.
Adjust the manhole height or angle. If nothing else works, cut a reinforcement ring instead.
1. Change the height and orientation of the manhole. 2. Reduce the number of bolts and make them thicker. 3. Modify the dimensions of the reinforcement ring, but it is necessary to conduct calculations first.
Try not to use cut reinforcement rings; other methods can be employed to increase the reinforcement area.

In cases where the cleaning hole reinforcement plate overlaps with the bolt seat plate, we simply eliminate the bolt seat plate and use the cleaning hole reinforcement plate as a substitute for it. If you’re still concerned, treat your anchor bolts as those without plates. Additionally, when considering the function of a plate for the bolt seat, the required size of such a plate turns out to be quite large, which is not only unsightly but also wasteful; it’s better to simply raise the bolt seat appropriately, ignore the role of a plate in the calculations, and then use a smaller plate, which can be cut to size as needed
1. To cut the reinforcement ring, calculations must be carried out in advance to determine how much needs to be cut, as long as it does not interfere with the anchor bolt seats, and to ensure that there is sufficient reinforcement area after cutting. If possible, make a design change. 2. To reduce the outer diameter of the reinforcement ring, calculations must be carried out in advance; the area loss resulting from the reduced diameter can be compensated for by increasing the thickness of the reinforcement ring. Attention must also be paid to the calculation of fiber elongation rates ； 3. Adjust the position of the manhole; there’s not much to say about this. If all the holes have already been drilled, then only the first two options remain.
