During the renovation of the fire water pipeline, the burial depth is higher than the local permafrost layer – what are the remedial measures?

Dear HaiChuan team: Our company is carrying out renovations to the underground fire protection pipelines. In order to avoid other pipelines that are buried underground, we have raised the elevation of certain sections of these fire protection pipelines. The depth of the permafrost layer in this area is 500, and currently the top of the fire protection pipelines is at a height of 380 above the ground level. Are there any remedial measures that can be taken?
Fill it in, turning it into a depth that meets the requirements for permafrost
What’s the distance? Just increase the burial depth
