The sealed concrete impermeability instrument is to make a judgment on the impermeability of cement injection, to detect the seepage of the outer cement surface after 24 hours of high-pressure water injection in the middle of the cement column, and to judge the qualified rate of cement. This scheme has been released before and lost due to some reasons, so it will be reissued. If there are any small partners who have seen it, then look at it again.
