The role of filter pipe and application areas:
In addition to entering the water, it can prevent particles of soil or rock around the well wall from flowing into the well to block the well pipe, and at the same time, it also plays the role of supporting and protecting the well wall so that the pumping hole can be used normally.  Some hard fissures, dissolved aquifers have stable wellbore walls and no loose fillers. No water filtration pipes are required for pumping. Loose pore-containing layers or fractured bedrock aquifers must be fitted with suitable water filtration pipes. . In the agricultural water supply wells, cement gravel filter pipes are also commonly used. The wells of the wells are actually used to filter water and purify water resources. At the same time, in large-scale national projects, such as the South-to-North Water Diversion Project, the Olympic Diving Site-Water Cube, and the East-West Transportation Project, high-quality water filtration pipes must be used.
