The length of small strain detection pile is generally less than 1 ~ 2m.

You can be sure, either you have problems with the whole batch of construction, and the previous tests were in a muddle, or you can take one and order more goods. Don't be afraid, even if there is a problem, as long as it is not excessive, this situation will eventually be solved, because it involves the responsibilities and interests of Party A, supervision and other parties. The solution is either to find someone to talk to him, find out the details, tell him that Party A thinks there is a problem, and ask for another test to see his reaction. I believe I will compromise in the end.
