Flexible permeable hose 
Flexible permeable hose is supported by anticorrosive spring rings to form an anti-high pressure structure.Besides, an additional non-woven cloth works as a filter to prevent the sand and soil from going into the pipe,thus purifying the water. Terylene threads on the outside surface enables the pipe to have a good sopping capacity and c ollect the superabundant water in the soil system. The rubber tendon enables the pipe wall to integrate well with the spring steel circle so that a omnidirectional penetrating function is realized, with the impurities like bedloads blocked out. In this way, penetration, filtering and drainage are done at the same time.
