Does this kind of pump with a "grouting hole cover" need a third grouting?
Thread Content
For this kind of pump with a "grouting hole cover", the first grouting is: After the initial leveling, fill the anchor bolt holes to the foundation surface. ； The second grouting refers to: After secondary leveling and spot welding of the pad iron, pour it to the base of the pump. ； Excuse me: Is a third grouting required? For example: Is the grouting material injected from the grouting hole cover (red circle in the picture)? If necessary, what grouting material is suitable? What details should be paid attention to?
Normally, pumps with "grouting hole covers" do not require a third grouting. The second grouting is enough to ensure the stability and safety of the pump. If you are very concerned about the stability of the pump, you can put some appropriate grout in the self-grouting hole cover. Note, however, that the quality of the grout must meet specifications and should be the same as the grout used previously. Also, make sure the grout hole covers are clear of debris so the grout can be poured directly into the holes. .
If grouting is required three times, use non-shrink grouting material, C60

This should be the secondary grouting port
It is recommended to perform grouting in accordance with GB 50204. Grouting makes the site hygienic and easy to maintain.
Personally, I think grouting is required, but on site there is usually a dispute between the construction unit and the owner. Who will pay for the three groutings?
It is best to carry out grouting three times to facilitate 6S management. For three times of grouting, even if Party B is required to do the work, Party B will charge extra. The wool comes from the sheep. If the owner chooses to do the construction by himself, there is no difficulty. There are ready-made "grouting materials" on the market.
This kind of grouting hole should also need to be filled with grouting material.
It is better to smooth the grout, otherwise it will be difficult to clean up water and oil leakage later.
