Is there any remedy for broken reinforcement bars in atmospheric-pressure steel sinks?

It is indeed possible to repair broken reinforcement bars in atmospheric-pressure steel sinks; the appropriate repair method usually depends on the degree and location of the break. Here are some possible remedies: 1. Welding repair: For small areas of fracture, they can be repaired by welding. Select appropriate welding electrodes and welding methods (such as arc welding, gas shielded welding, etc.) to weld and reinforce the fractured stiffeners. After repair, heat treatment should be carried out to eliminate welding stresses, followed by non-destructive testing to verify the quality of the repair. 2. Reinforcement plate: If the fractured area is large, a reinforcement plate can be installed on the fractured stiffener. The reinforcement plate must be firmly connected to the existing structure using bolts or welding, etc., to ensure that its load-bearing capacity meets the requirements of use. 3. Replace the reinforcement bar: If the reinforcement bar is severely damaged, it may be necessary to remove the entire bar and replace it with a new one. When replacing the new reinforcement bars, it is necessary to ensure that their material, dimensions, and properties meet the design requirements, and they should be secured using appropriate connection methods. 4. Repair using adhesives: For some small cracks, suitable engineering adhesives can be used to fill and seal them, thereby restoring their load-bearing capacity. When selecting a binder, the suitability of the material must be considered (such as temperature range, chemical stability, etc.). Before carrying out any repair work, it is necessary to first assess the extent of the damage and the safety of the sink. It is important to engage qualified professionals for the assessment and repair work, to ensure that the sink can be used safely again after repairs. At the same time, relevant safety procedures and industrial standards must be followed during repair work. After the repair is completed, appropriate tests should be carried out to verify the effectiveness of the fix. .

It seems to me that those two sections of channel steel are joined together; it’s likely that after welding they were polished flat, resulting in insufficient weld strength. Given the height of your water tank, it should not exceed 3 meters, and standard national-specification channel steel should not break under such conditions. Of course, I’m not aware of the exact dimensions of your water tank or the layout of its reinforcement bars

Can’t you add another horizontal reinforcement ring below? It’s supposed to be denser at the bottom and sparser at the top; depending on the situation, vertical reinforcements can also be added

Pay attention to inspections and interlocks for this. Moreover, you didn’t perform full welding; we did full welding, it just swelled up but didn’t crack.

Drain the water completely, restore the reinforcement bars to their original position, then add shims for welding; note that the welding spacing for the reinforcement bars should be 250@50 with gaps between welds.

It appears to be a rectangular container; if its height is 2.2 meters or less, only the vertical reinforcement columns need to be recalculated, without the need to consider the horizontal reinforcement rings. The cracks are likely caused by insufficient section modulus of the vertical reinforcement columns. Use a larger section of steel; for example, with channel steel, the side with the smaller cross-section should be welded to the wall.

Use small H-shaped steel or angle steel, and weld them inside the original flange plate.
