What is the correct assumption of the support/restraint acting on a pipe that penetrates through a earth dike with 90% compactness? 2 support have already been provided before & after the bund. Therefore the loads will be carried by these support and not the point where the pipe penetrates. But since the compactness is 90%, will it somehow (point where the pipe penetrates) act as a support? If it is, is it a ystop&guide with 0 mm gap? Since earth dike just containing soil, which might loosen as time goes, can it act as an anchor?

Thank you in advanced
