In areas with high groundwater levels, in order to ensure that groundwater does not affect the normal operation of the direct buried pipeline, the outer protective layer is made of a strong, sealed steel casing. The so-called upper hydrophobicity is to pass the condensed water in the pipeline through the hydrophobic pipe inserted into the working steel pipe, and the condensed water in the water collecting tank utilizes the back pressure in the pipeline to discharge the condensed water from the upper part of the pipeline.
