  • Publication number: 20070251877
    Abstract: A pipe element structure comprises a pipe body which comprises an exterior pipe, an intermediate filtration pipe and an interior filtration pipe. The exterior pipe has multiple openings on its surface. The intermediate and interior filtration pipes are made of porous materials. As the pipe body being buried in the ground, the exterior pipe filters out soils in bigger particle size by the openings whereas allows soil and water to sink in, and piles up effectively inside. The intermediate filtration pipe filters out the soil-water to isolate soil particles. The water is filtrated down into the interior filtration pipe free of blocking or clogging.
